This heading covers polystyrene and copolymers of styrene. The most important copolymers of styrene are styrene‑acrylonitrile (SAN) copolymers, acrylonitrile‑butadiene‑styrene (ABS) copolymers and styrene‑butadiene copolymers. Most of the styrene‑butadiene copolymers with substantial amounts of butadiene comply with the requirements of Note 4 to Chapter 40 and are therefore classified in Chapter 40 as synthetic rubber. For the classification of polymers (including copolymers), chemically modified polymers and polymer blends, see the General Explanatory Note to this Chapter.

Unexpanded polystyrene is a colourless, transparent, thermoplastic material which finds extensive use in the electrical and radio industries. It also has packaging applications, for example, in the packaging of foodstuffs and cosmetics. It is also used in the manufacture of toys, clock cabinets and gramophone records.

Expanded (cellular) polystyrene contains gases from the expanding process and has a low bulk‑density. It is extensively used as a thermal insulent for refrigerator doors, air‑conditioner housings, cold storage facilities, freezer display cabinets, and in the construction industry. It is also used in disposable packaging and in food serving articles.

Certain chemically modified copolymers of styrene are ion‑exchangers (heading 39.14).

Styrene‑acrylonitrile (SAN) copolymers, which have high tensile strength, good mouldability and chemical resistance, are used for making cups, tumblers, typewriter keys, refrigerator parts, oil‑filter bowls and certain kitchen equipment. Acrylonitrile‑butadiene‑styrene (ABS) copolymers, which have high shock and weather resistance, are used in the manufacture of parts and accessories of bodies for motor vehicles, of refrigerator doors, of telephones, of bottles, of shoe heels, of cases for machines, of water pipes, of building panels, of vessels, etc.

FAQs

What is HS code 3903?

HS code 3903 includes Plastics and articles thereof - Polymers of styrene, in primary forms..

How many sub-headings are there in HS code 3903?

There are 5 sub-heading(s) in HS code 3903.

What is an HS Code and Why Does it Hold For Cross-Border Trade?

HS code is a standardized six-digit numerical classification system developed by the World Customs Organization (WCO) and acts as a universal language for simplifying the process of identifying and classifying traded products. They ensure consistent customs clearance, enable accurate duty calculation, and help identify relevant trade regulations. This simplifies the process for businesses, saving time, reducing risk, and promoting informed decision-making.

What are Controls and Why should Businesses Focus on Them?

In global trade, controls refer to a set of regulations and policies implemented by governments to manage the import and export of goods and services. These controls can take various forms, including tariffs, quotas, embargoes, export controls, and licensing requirements. Companies should prioritize understanding and adhering to them for compliance, reduced risk of legal issues, mitigating reputational damage, staying competitive, and building trust with governments.

What are Tariffs in Global Trade and Why should Businesses Focus on Them?

In global trade, tariffs are a type of tax levied by a government on imported goods. They act as a financial barrier to entry, increasing the overall cost of the imported product for domestic consumers and businesses. By understanding how tariffs work and their potential impact, companies can make informed decisions about pricing, sourcing, and market expansion, ultimately ensuring their competitiveness in the global marketplace.

What are FTAs in Global Trade and Why should Businesses Focus on Them?

In global trade, Free Trade Agreements (FTAs) are legally binding agreements between two or more countries aimed at reducing or eliminating barriers to trade between them. By understanding the terms of relevant FTAs and strategically incorporating them into their business plans, companies can enjoy reduced costs, expanded market access, and a more competitive edge in international trade.
