HS 290250 Styrene

Quick Answer: HS code 290250 specifically covers Styrene, a fundamental organic chemical compound (vinylbenzene) primarily used in the production of polymers like polystyrene, ABS, and SBR rubber. Importers and exporters should note that this commodity generally faces a 0.00% ad valorem duty rate in both the UK (per the UK Trade Tariff) and the EU (per TARIC). However, imports into the United States (per the USITC Harmonized Tariff Schedule) can be subject to a more complex duty structure, potentially including a Free rate, or a compound rate of 15.4¢/kg + 45% ad valorem, depending on specific trade agreements or country of origin. Due to its widespread industrial use, accurate classification is crucial for compliance and duty optimization.

How to Classify This HS Code?

What products does HS 290250 cover?

This subheading covers styrene, a colorless, oily liquid organic chemical compound with the chemical formula C8H8. It is an aromatic hydrocarbon characterized by a vinyl group attached to a benzene ring. As defined by the World Customs Organization (WCO) Harmonized System Explanatory Notes for Heading 2902, this specific subheading is reserved solely for styrene in its chemically defined pure form. Both the USITC Harmonized Tariff Schedule (HTSUS) and the EU TARIC system align with this definition, classifying only the isolated chemical compound styrene under this code, typically used as a monomer in the production of polystyrene and other polymers.

What falls outside HS 290250?

The following products are excluded from HS 290250: mixtures containing styrene with other substances, even if styrene is the predominant component, which would generally be classified under Heading 3824 if they are not elsewhere specified or included. Furthermore, polymers of styrene, such as polystyrene in primary forms (e.g., granules, powders), are specifically excluded and classified under Chapter 39, typically Heading 3903. For instance, styrene-butadiene rubber (SBR) is classified under Chapter 40, specifically Heading 4002, as a synthetic rubber, not as a pure chemical compound.

What are common classification mistakes for HS 290250?

A common error is misclassifying mixtures containing styrene under HS 290250. General Interpretative Rule (GRI) 1 dictates that classification is determined according to the terms of the headings and any relative section or chapter notes. GRI 3(b) would apply to mixtures, often leading to classification based on the component that gives the mixture its essential character, or under the heading for goods consisting of the greatest weight or volume. For example, a solution of styrene in a solvent, even if primarily styrene, is not "chemically defined pure" styrene and would likely fall under a different heading, such as 3824, depending on its composition and use.

How should importers classify products under HS 290250?

The correct procedure for classifying products under HS 290250 requires strict adherence to the "chemically defined pure" criterion. Importers and customs brokers must obtain and review the Certificate of Analysis (CoA) or Safety Data Sheet (SDS) for the product to confirm its chemical purity and ensure it consists solely of styrene (C8H8) without significant impurities or other added substances. If the product is a mixture or a polymer, it must be classified elsewhere, typically in Chapter 38 or 39, respectively. Consulting the WCO Explanatory Notes for Chapter 29 and Heading 2902 is crucial to confirm that the product meets the stringent definition of a pure organic chemical compound.

FAQ

What are the typical Most Favored Nation (MFN) import duty rates for Styrene (HS 2902.50) in major markets?

The MFN duty rates for Styrene (HS 2902.50) can vary significantly by importing country. For instance, under the Harmonized Tariff Schedule of the United States (HTSUS), the general MFN duty rate for 2902.50.00.00 is 'Free' (0.00% ad valorem). In contrast, some developing economies or specific trade blocs might apply duties. Importers should consult the specific country's tariff schedule, such as the USITC HTSUS, EU TARIC, or the UK Trade Tariff, for the precise and current MFN rate applicable to their destination market.

Are there any preferential duty rates available for Styrene under common Free Trade Agreements (FTAs) or Generalized System of Preferences (GSP) programs?

Yes, preferential duty rates, often 'Free' (0.00% ad valorem), are frequently available for Styrene (HS 2902.50) under various Free Trade Agreements (FTAs) and Generalized System of Preferences (GSP) programs. For example, imports into the United States from FTA partner countries (e.g., USMCA, CAFTA-DR, KORUS) or eligible GSP beneficiary countries may qualify for duty-free treatment, provided all rules of origin requirements are met. Importers must ensure they have the correct certificates of origin (e.g., NAFTA/USMCA Certificate of Origin, GSP Form A) to claim these preferential rates. Always verify the specific agreement's rules of origin for HS 2902.50.

What are the key classification criteria for ensuring Styrene is correctly classified under HS 2902.50?

The classification of Styrene under HS 2902.50 is generally straightforward as it is a pure chemical compound. The primary criterion is its chemical identity as 'Styrene' (vinylbenzene, phenylethylene), an aromatic hydrocarbon with the chemical formula C8H8. It falls under Chapter 29, which covers 'Organic chemicals,' and specifically within subheading 2902 for 'Cyclic hydrocarbons.' Subheading 2902.50 is explicitly designated for 'Styrene.' Importers should ensure that the product being imported is indeed pure styrene and not a mixture, derivative, or polymer, which would fall under different HS codes (e.g., polymers of styrene are in Chapter 39). Purity specifications on the Certificate of Analysis (CoA) are crucial for confirming classification.

What specific documentation is typically required by customs authorities for the import of Styrene (HS 2902.50)?

For the import of Styrene (HS 2902.50), standard customs documentation includes a Commercial Invoice, Packing List, Bill of Lading or Air Waybill, and a Certificate of Origin. Additionally, due to its chemical nature, a Material Safety Data Sheet (MSDS) or Safety Data Sheet (SDS) is often required by regulatory bodies (e.g., EPA in the US, ECHA in the EU) for hazard communication and chemical inventory purposes. A Certificate of Analysis (CoA) confirming the purity and specifications of the styrene is also highly recommended and often requested by customs or consignees to validate the product's identity and quality. For preferential duty claims, a valid Certificate of Origin specific to the trade agreement is mandatory.
