From UPSC perspective, the following things are important :
Prelims level: G4 Flu
Mains level: Rise in zoonotic diseases and their possible causes
In new research, scientists from China – which has the largest population of pigs in the world – have identified a “recently emerged” strain of influenza virus that is infecting Chinese pigs and that has the potential of triggering a pandemic.
Practice question for mains:
Q.What are zoonotic diseases? Why China has emerged as the epicentre of global outbreaks of zoonotic disease?
G4 Flu
- Named G4, the swine flu strain has genes similar to those in the virus that caused the 2009 flu pandemic.
- The scientists identified the virus through surveillance of influenza viruses in pigs that they carried out from 2011 to 2018 in ten provinces of China.
- They also found that the G4 strain has the capability of binding to human-type receptors (like, the SARS-CoV-2 virus binds to ACE2 receptors in humans).
- The virus was able to copy itself in human airway epithelial cells, and it showed effective infectivity and aerosol transmission.
Swine industry is the new hotspot for zoonoses
- The scientists report that the new strain (G4) has descended from the H1N1 strain that was responsible for the 2009 flu pandemic.
- Pigs are intermediate hosts for the generation of pandemic influenza virus.
- Thus, systematic surveillance of influenza viruses in pigs is a key measure for pre-warning the emergence of the next pandemic influenza.
Back2Basics: 2009 swine flu pandemic
- The WHO declared the outbreak of type A H1N1 influenza virus a pandemic in 2009 when there were around 30,000 cases globally.
- It was caused by a strain of the swine flu called the H1N1 virus, which was transmitted from human to human.
- Influenza viruses that commonly circulate in swine are called “swine influenza viruses” or “swine flu viruses”.
- Like human influenza viruses, there are different subtypes and strains of swine influenza viruses. Essentially, swine flu is a virus that pigs can get infected by.
- The symptoms of swine flu include fever, cough, sore throat, body aches, headaches, chills and fatigue.

From UPSC perspective, the following things are important :
Prelims level: Gold Nanoparticles
Mains level: Applications of nanomaterials
Indian researchers have successfully synthesized gold nanoparticles (GNPs) using psychrotolerant Antarctic bacteria through a non-toxic, low-cost, and eco-friendly way.
Nanotechnology is a pathbreaking technology which can create many new materials and devices with a wide range of applications, such as in nanomedicine, nanoelectronics etc. GNPs are another distinct development.
What are Gold Nanoparticles?
- Metallic NPs have been efficiently exploited for biomedical applications and among them, GNPs are found to be effective in biomedical research.
- And NPs are those materials that are at least one dimension smaller than 100 nanometers.
- NPs have a high surface-to-volume ratio and they can provide the tremendous driving force for diffusion, especially at elevated temperatures.
- GNPs are melted at much lower temperatures (300 °C) than bulk gold (1064 °C).
- NPs have been found to impart various desirable properties to different day-to-day products.
- For example, GNPs are found to have greater solar radiation absorbing ability than the conventional bulk gold, which makes them a better candidate for use in the photovoltaic cell manufacturing industry.
Properties of GNP
1) Biomedical
- Genotoxicity describes the property of a chemical agent that is capable of damaging the genetic information of DNA and thus causing the mutation of the cell, which can lead to cancer.
- The study revealed the genotoxic effect of GNPs on a sulphate reducing bacteria (SRB).
- These GNPs can be used as composite therapeutic agent clinical trials, especially in anti-cancer, anti-viral, anti-diabetic, and cholesterol-lowering drugs.
2) Optical
- GNPs have unique optical properties too. For example, particles above 100 nm show blue or violet colour in the water, while the colour becomes wine red in 100 nm gold colloidal particles.
- They can thus be used for therapeutic imaging.
3) Electronics
- GNPs are also found to be useful in the electronics industry.
- Scientists have constructed a transistor known as NOMFET (Nanoparticles Organic Memory Field-Effect Transistor) by embedding GNPs in a porous manganese oxide.
- NOMFETs can mimic the feature of the human synapse known as plasticity or the variation of the speed and strength of the signal going from neuron to neuron.
- These novel transistors can now facilitate better recreation of certain types of human cognitive processes, such as recognition and image processing and have their application in AI.

Kholongchhu Hydel Project
- The Kholongchhu project is regarded as a “milestone” in the India-Bhutan partnership, under which four hydropower projects have been built in the last 30 years totalling a capacity of 2,100 MW.
- It is one of four additional projects agreed to in 2008, as a part of India’s commitment to helping Bhutan create a total 10,000 MW of installed capacity by 2020.
- The project is located at the lower course of Kholongchhu just before its confluence with Drangmechu (Gongrichu) in Trashiyangtse District of Bhutan.
- The GoI will provide, as a grant, the equity share of the Bhutanese DGPC in the JV Company.
- Once the project is commissioned, the JV partners will run it for 30 years, called the concession period, after which the full ownership will transfer to the Bhutan government.
Whats’ so special with the project?
- It is the first hydropower joint venture project in Bhutan’s less developed eastern region of Trashiyangtse.
- It is the first time an India-Bhutan hydropower project will be constructed as a 50:50 joint venture and not as a government-to-government agreement.

(a) Bacteria (b) Protozoa (c) Moulds (d) Viruses
Gynandromorphism
- Gynandromorphs are individual animals that have both genetically male and female tissues and often have observable male and female characteristics.
- They may be bilateral, appearing to divide down the middle into male and female sides, or they may be mosaic, with patches characteristic of one sex appearing in a body part characteristic of the other sex.
- Gynandromorphs occur in insects, spiders, crustaceans, and other arthropods as well as in birds, but they are extremely rare, and discovering one in the field or in the laboratory is a major event.
- Estimating how frequently they occur is difficult because they usually go unnoticed in species where sexual dimorphism is less pronounced.
- Gynandromorphs have been reported in mosquitoes, fruit flies, and in other insects, but they are most dramatic in those butterfly species in which the male and female wing colours and patterns are dramatically different.

Try this question from CSP 2012:
Q.What is the difference between the antelopes’ Oryx and Chiru?
(a) Oryx is adapted to live in hot and arid areas like Africa and Arabia whereas Chiru is adapted to live in steppes and semi-desert areas of cold high mountains of Tibetan Plateau.
(b) Oryx is poached for its antlers whereas Chiru is poached for its musk
(c) Oryx exists in western India only whereas Chiru exists in northeast India only.
(d) None of the statements (a), (b) and (c) given above is correct.
Jungle Fowl
- The DNA sequencing of 863 genomes has shown the first domestication of chicken occurred in southwestern China, northern Thailand and Myanmar.
- The study involved sequencing of genomes from all four species of the genus Gallus, five subspecies of Red Jungle Fowl and various domestic chicken breeds collected worldwide.
- It revealed single domestication from Red Jungle Fowl sub-species Gallus spadiceous.
- The study also demonstrated that all five Red Jungle Fowl sub-species were genetically differentiated from each other approximately 50,000 years ago much earlier than domestication.
- The results contradicted the earlier claim that chickens were domesticated in northern China and the Indus Valley.
Domestication of Chicken
- The question of domestication of chickens has intrigued scientists for centuries and has been the subject of debate.
- Charles Darwin postulated that chickens were domesticated around 4,000 B.C. from a single ancestor, Red Jungle Fowl in the Indus Valley.
- An important study published earlier from Uppsala University claimed the Grey Jungle Fowl had contributed to chicken domestication.
- With this, a couple of studies from India, China and other South-Asian countries have argued the monophyletic origin of chicken.

Recently, Assam CM ordered the arrest of a political commentator who had described Chaolung Sukapha as a “Chinese invader”.
Practice question for mains:
Q. Who are the Ahoms? Describe the role of Ahom Kingdom in cultural assimilation of modern-day Assam.
Who was Chaolung Sukapha?
- Sukapha was a 13th-century ruler who founded the Ahom kingdom that ruled Assam for six centuries. Contemporary scholars trace his roots to Burma.
- He reached Brahmaputra valley in Assam from upper Burma in the 13th century with around 9,000 followers.
- Sukapha is said to have left a place called Maulung ( in Yunnan, China ) in AD 1215 with eight nobles and 9,000 men, women and children — mostly men.
- In 1235, Sukapha and his people settled in Charaideo in upper Assam after wandering about for years, defeating those who protested his advance and temporarily staying at different locations.
- It was in Charaideo (in Assam) that Sukapha established his first small principality, sowing the seeds of further expansion of the Ahom kingdom.
Who are the Ahoms today?
- The founders of the Ahom kingdom had their own language and followed their own religion.
- Over the centuries, the Ahoms accepted the Hindu religion and the Assamese language, scholars say.
- The Ahoms embraced the language, religion and rituals of the communities living here — they did not impose theirs on those living here.
- Today, the Ahom community is estimated to number between 4 million and 5 million.
Why is Sukapha important in Assamese culture?
- Sukapha’s significance — especially in today’s Assam — lies in his successful efforts towards the assimilation of different communities and tribes.
- He developed very amicable relationships with the tribal communities living here — especially the Sutias, the Morans and the Kacharis.
- Intermarriage also increased assimilation processes. He is widely referred to as the architect of “Bor Asom” or “greater Assam”.

Prelims level: Solar Eclipse and related terms, Summer Solstice
Mains level: Not Much
A rare celestial event, an annular solar eclipse popularly called as the ‘ring of fire’ eclipse, will be visible on June 21, 2020 from some parts of Northern India. The first solar eclipse of this year takes place on the summer solstice, which is the longest day in the Northern Hemisphere.
Try this question from CSP 2019:
Q. On 21st June, the Sun
(a) Does not set below the horizon at the Arctic Circle
(b) Does not set below the horizon at Antarctic Circle
(c) Shines vertically overhead at noon on the Equator
(d) Shines vertically overhead at the Tropic of Capricorn
What is the Solar Eclipse?
- A Solar Eclipse happens when the moon while orbiting the Earth comes in between the sun and the Earth, due to which the moon blocks the sun’s light from reaching the Earth, causing an eclipse of the sun or a solar eclipse.
- According to NASA, people who are able to view the total solar eclipse are in the centre of the moon’s shadow as and when it hits the Earth.
- There are three types of eclipses: one is a total solar eclipse, which is visible only from a small area on Earth. A total solar eclipse happens when the sun, moon and Earth are in a direct line.
- The second type of a solar eclipse is a partial solar, in which the shadow of the moon appears on a small part of the sun.
Annular Solar Eclipse
- The third kind is an annular solar eclipse, which happens when the moon is farthest from the Earth, which is why it seems smaller.
- In this type of an eclipse, the moon does not block the sun completely, but looks like a “dark disk on top of a larger sun-coloured disk” forming a “ring of fire”.
- Furthermore, during a solar eclipse, the moon casts two shadows on the Earth; the first one is called the umbra, which gets smaller as it reaches the Earth.
- The second one is called the penumbra, which gets larger as it reaches the Earth.
- According to NASA, people standing in the umbra see a total eclipse and those standing in the penumbra see a partial eclipse.
Why the study of solar eclipse is crucial?
- One of the reasons that NASA studies solar eclipses is to study the top layer of the sun called the corona.
- During an annular eclipse, NASA uses ground and space instruments to view this top layer when the sun’s glare is blocked by the moon.
Back2Basics: Summer Solstice
- The summer solstice occurs when one of the Earth’s poles has its maximum tilt toward the Sun.
- It happens twice yearly, once in each hemisphere (Northern and Southern).
- For that hemisphere, the summer solstice is when the Sun reaches its highest position in the sky and is the day with the longest period of daylight.
- Within the Arctic circle (for the northern hemisphere) or Antarctic circle (for the southern hemisphere), there is continuous daylight around the summer solstice.
- On the summer solstice, Earth’s maximum axial tilt toward the Sun is 23.44°. Likewise, the Sun’s declination from the celestial equator is 23.44°.

Prelims level: Megaliths
Mains level: Not Much
The Kodumanal excavation in Erode Dist. of Tamil Nadu has threw light on burial rituals and the concept of afterlife in megalithic culture.
Must read:
Chapter 1 | Stone Age – Paleolithic, Mesolithic and Neolithic
About these sites
- The researchers have identified 250 cairn-circles at the village in Erode district.
- Earlier excavations revealed that the site served as a trade-cum-industrial centre from 5th century BCE to 1st century BCE.
- The rectangular chambered cists, each two metres long and six metres wide, are made of stone slabs, and the entire grave is surrounded by boulders that form a circle.
- The grave could be of a village head or the head of the community as the size of two boulders, each facing east and west, are bigger than other boulders.
- Believing that the deceased person will get a new life after death, pots and bowls filled with grains were placed outside the chambers.
What are Megaliths?
- Megaliths are the earliest surviving man-made monuments we know of—derived from the Latin mega (large) and lith (stone).
- Megaliths were constructed either as burial sites or commemorative (non-sepulchral) memorials.
- The former are sites with actual burial remains, such as dolmenoid cists (box-shaped stone burial chambers), cairn circles (stone circles with defined peripheries) and capstones (distinctive mushroom-shaped burial chambers found mainly in Kerala).
- The urn or the sarcophagus containing the mortal remains was usually made of terracotta.
- Non-sepulchral megaliths include memorial sites such as menhirs. (The line separating the two is a bit blurry, since remains have been discovered underneath otherwise non-sepulchral sites, and vice versa.)
- In India, archaeologists trace the majority of the megaliths to the Iron Age (1500 BC to 500 BC), though some sites precede the Iron Age, extending up to 2000 BC.
Megaliths in India
- Megaliths are spread across the Indian subcontinent, though the bulk of them are found in peninsular India, concentrated in the states of Maharashtra (mainly in Vidarbha), Karnataka, Tamil Nadu, Kerala, Andhra Pradesh and Telangana.
- According to archaeologists around 2,200 megalithic sites can be found in peninsular India itself, most of them unexcavated.
- Even today, a living megalithic culture endures among some tribes such as the Gonds of central India and the Khasis of Meghalaya.
Literary sources
- Megalithic culture finds several references in ancient Tamil Sangam literature. For instance, menhirs are referred to as nadukal.
- Ancient Sangam texts lay out, in detail, a step-by-step procedure for laying a memorial stone or nadukal in honour of a fallen hero.
- Manimekalai (5th century AD), the famous Sangam epic, refers to the various kinds of burials namely cremation (cuṭuvōr), post excarnation burial (iṭuvōr), burying the deceased in a pit (toṭukuḻip paṭuvōr), rock chamber or cist burial (tāḻvāyiṉ aṭaippōr), urn burial encapped with lid (tāḻiyiṟ kavippōr).
- Even in the Sangam age (when kingship and a well-ordained society had emerged) the above modes of burials survived.

Which of the statements given above is/are correct?
(a) 1, 2 and 3.
(b) 1 and 3 only
(c) 2 and 3 only

Talamaddale theatre
- Tala-Maddale is an ancient form of performance dialogue or debate performance in Southern India in the Karavali and Malnad regions of Karnataka and Kerala.
- The plot and content of the conversation is drawn from popular mythology but the performance mainly consists of an impromptu debate between characters involving sarcasm, puns, philosophy positions and humour.
- The main plot is sung from the same oral texts used for the Yakshgana form of dance- drama.
- Performers claim that this was a more intellectual rendition of the dance during the monsoon season.
How it is different from Yakshagana?
- Unlike the Yakshagana performance, in the conventional ‘talamaddale,’ the artists sit across in a place without any costumes and engage in testing their oratory skills based on the episode chosen.
- If music is common for both Yakshagana performance and ‘talamaddale’, the latter has only spoken word without any dance or costumes.
- Hence it is an art form minus dance, costumes and stage conventions.
- It has an ‘arthadhari’ who is an orator, a ‘bhagavatha’ (singer-cum-director), and a ‘maddale’ player.
Back2Basics: Yakshagana
- It is the oldest theatre form popular in Karnataka.
- It emerged in the Vijayanagara Empire and was performed by Jakkula Varu
- It is a descriptive dance drama.
- It is presented from dusk to dawn.
- The stories are drawn from Ramayana, Mahabharata and other epics from both Hindu and Jain tradition.

Practice question for mains:
Q. What are Zoonotic Diseases? Discuss the hazards of importing zoonotic diseases through wildlife trade.
About Pangolin
IUCN status: Endangered
- India is home to two species of pangolin.
- While the Chinese Pangolin (Manis pentadactyla) is found in northeastern India, the Indian Pangolin is distributed in other parts of the country as well as Sri Lanka, Bangladesh and Pakistan.
- Both these species are protected and are listed under the Schedule I Part I of the Wild Life (Protection) Act, 1972 and under Appendix I of the Convention on International Trade in Endangered Species (CITES).
- Commonly known as ‘scaly anteaters’, the toothless animals are unique, a result of millions of years of evolution.
- Pangolins evolved scales as a means of protection. When threatened by big carnivores like lions or tigers they usually curl into a ball.
- The scales defend them against dental attacks from the predators.
Pangolin in China
- Pangolin meat is considered a delicacy in China and Vietnam.
- Their scales which are made of keratin, the same protein present in human nails — are believed to improve lactation, promote blood circulation, and remove blood stasis.
- These so-called health benefits are so far unproven.
What makes pangolins the most trafficked animals in the world?
- Their alleged health benefits in traditional Chinese medicines prompted a booming illicit export of scales from Africa over the past decade.
- Officials quote trafficking price of Pangolin and its scale anywhere between Rs 30,000 and Rs 1 crore for a single animal.
- Conservation of pangolins received its first shot in the arm when the 2017 Convention on International Trade in Endangered Species (CITES) enforced an international trade ban.
How will China’s decision impact pangolin trafficking?
- The immediate impact would be pangolin scales losing their legitimacy in traditional Chinese medicines. However, the history of the ban on wildlife trade in China is not encouraging.
- The continued availability of tiger bone wine — believed to cure a host of conditions ranging from dysentery to rheumatism — despite its ban on tiger products in 1993. The price of elephant ivory plummeted by two-thirds after China banned it.
- India, where the trade largely remains local, has been registering a decline from before China’s ban.
- The trade-in pangolin scales are already showing a decreasing trend in India and the only trade is the trade-in live animals by unorganised traders, who ask for a few crores for each live animal.

From UPSC perspective, the following things are important :
Prelims level: BECs
Mains level: Various properties of BECs
Scientists have observed the fifth state of matter in space for the first time, offering unprecedented insight that could help solve some of the quantum universe’s most intractable conundrums.
Try this question from CSP 2018
Q. Consider the following phenomena:
- Light is affected by gravity.
- The Universe is constantly expanding.
- Matter warps its surrounding space-time.
Which of the above is/are the prediction/predictions of Albert Einstein’s General Theory of Relativity, often discussed in media?
(a) 1 and 2 only
(b) 3 only
(c) 1 and 3 only
(d) 1, 2 and 3
Bose-Einstein condensates (BECs)
- Bose-Einstein condensates (BECs) — the existence of which was predicted by Albert Einstein and Indian mathematician Satyendra Nath Bose almost a century ago — are formed when atoms of certain elements are cooled to near absolute zero (0 Kelvin, minus 273.15 Celsius).
- At this point, the atoms become a single entity with quantum properties, wherein each particle also functions as a wave of matter.
- BECs straddle the line between the macroscopic world governed by forces such as gravity and the microscopic plane, ruled by quantum mechanics.
Why are BECs important?
- Scientists believe BECs contain vital clues to mysterious phenomena such as dark energy — the unknown energy thought to be behind the Universe’s accelerating expansion.
- But BECs are extremely fragile. The slightest interaction with the external world is enough to warm them past their condensation threshold.
- This makes them nearly impossible for scientists to study on Earth, where gravity interferes with the magnetic fields required to hold them in place for observation.
Studying BECs
- NASA scientists unveiled the first results from BEC experiments aboard the International Space Station (ISS), where particles can be manipulated free from Earthly constraints.
- The microgravity onboard the ISS allowed them to create BECs from rubidium — a soft metal similar to potassium — on a far shallower trap than on Earth.
- Microgravity at ISS allows confining atoms with much weaker forces. Microgravity also allowed the atoms to be manipulated by weaker magnetic fields, speeding their cooling and allowing clearer imaging.
- Creating the fifth state of matter, especially within the physical confines of a space station, is no mean feat for NASA.

From UPSC perspective, the following things are important :
Prelims level: GST slabs on food items
Mains level: Not Much
A recent GST ruling sparked off the debate with the Authority for Advance Rulings (AAR, Karnataka Bench) suggesting parottas would be subject to a higher GST rate of 18 per cent as compared to roti.
Try this question from CSP 2018:
Q. Consider the following items:
- Cereal grains hulled
- Chicken eggs cooked
- Fish processed and canned
- Newspapers containing advertising material
Which of the above items is/are exempt under GST (Goods and Services Tax)?
(a) 1 only
(b) 2 and 3 only
(c) 1, 2 and 4 only
(d) 1, 2, 3 and 4
What is the Case?
- Bengaluru-based food products company involved in preparation and supply of ready-to-cook items had approached the AAR regarding whether preparation of whole wheat parotta and Malabar parotta attracting 5 per cent GST.
- The products khakhra, plain chapatti and roti are completely cooked preparations, do not require any processing for human consumption and hence are ready to eat food preparations.
- The impugned product (whole wheat Parottas and Malabar Parottas) are not only different from the said khakhras, plain chapatti or roti but also are not like products in common parlance as well as in the respect of essential nature of the product.
Classification of food items for GST
- Most food items, especially those of essential and unprocessed nature, are charged nil GST.
- But processed foods attract higher rates of 5%, 12%, or 18% depending on the food product.
- For instance, pappad, Bread (branded or otherwise), are charged zero GST, but pizza bread is charged 5% GST.
- Heading 1905 under the Harmonised Commodity Description and Coding System classifies pizza bread, khakhra, plain chapati or roti, rusks, toasted bread in one category, for which a 5% GST rate is levied.
- Similarly, in the ready for consumption category, unbranded namkeens, bhujia, mixture and similar edible preparation attract 5% GST, while such branded namkeen, bhujia, mixture attract 12% GST.

Prelims level: Raja Parba
Mains level: NA
The Prime Minister has extended his greetings to the people of Odisha for the unique Raja Parba festival.
Match the pair based question can be asked from festivals as such with pairs of name and celebrating state. Recently, the following festivals were also in the news: Ambubachi Mela, Thrisoor Puram, Meru Jatara, Nagoba Jatara etc.
Also, note the similarities between the Raja Parba and Ambubachi Mela …
About Raja Parba Festival
- Raja Parba is Odisha’s three-day unique festival celebrating the onset of monsoon and the earth’s womanhood.
- As a mark of respect towards the earth during her menstruation days, all agricultural works, like ploughing, sowing is suspended for the three days.
- Raja Sankranti is the first day of the Ashara month.
- It is celebrated on the day prior to the Sankranti, (Pahili Raja), the day of Sankranti, and the day after, known as Bhu Daha or ‘Basi Raja.
- The festival is essentially the celebration of the earth’s womanhood.
- It is believed that during this time the Mother Earth or Bhudevi undergoes menstruation.
- The fourth day is the day of the ‘purification bath’.

From UPSC perspective, the following things are important :
Prelims level: BAT, Customs Duty
Mains level: Not Much
A notable NITI Aayog member has favoured imposing a Border Adjustment Tax (BAT) on imports to provide a level-playing field to domestic industries.
Note how BAT is different from the Custom Duties on imports. Refer to our B2B section.
What is the proposed Border Adjustment Tax?
- BAT is a duty that is proposed to be imposed on imported goods in addition to the customs levy that gets charged at the port of entry.
- It is proposed to be a non-creditable levy on imported goods. The idea is to bring similar goods in the imported and domestic baskets at par.
Why need BAT?
- Generally, BAT seeks to promote “equal conditions of the competition” for foreign and domestic companies supplying products or services within a taxing jurisdiction.
- The Indian industry has been complaining to the government about domestic taxes like electricity duty, duties on fuel, clean energy cess, mandi tax, royalties, biodiversity fees that get charged on domestically produced goods as these duties get embedded into the product.
- But many imported goods do not get loaded with such levies in their respective country of origin and this gives such products price advantage in the Indian market.
Will it be WTO compatible?
- Countries that are members of Geneva-based global watchdog WTO have locked the upper limits of customs levies for product lines that they trade-in.
- Any additional duty that gets imposed by WTO members are scoffed upon and in many instances, extra customs duties led to countries being dragged to international arbitration under WTO.
- Commerce Ministry believes that the proposed extra customs duty through the Border Adjustment Tax is compatible with global trade norms.
- Officials maintain that Article II: 2(a) of GATT allows for import charge that is equal to the internal tax of the country with respect to a “Like Product” or an item from which the imported product is made. Legal opinion on the proposed levy has also been taken.
Back2Basics: Customs Duty
- It refers to the tax imposed on the goods when they are transported across international borders.
- The objective behind levying customs duty is to safeguard each nation’s economy, jobs, environment, residents, etc., by regulating the movement of goods, especially prohibited and restrictive goods, in and out of any country.
Customs duties are charged almost universally on every good which are imported into a country. Some of these are:
- Basic Customs Duty (BCD)
- Countervailing Duty (CVD)
- Protective Duty
- Anti-dumping Duty etc.
