HS 293211 Compounds containing an unfused furan ring (whether or not hydrogenated) in the structure
Quick Answer: HS code 2932.11 covers organic chemical compounds characterized by an unfused furan ring within their molecular structure, whether or not the ring is hydrogenated. This includes chemicals like tetrahydrofuran (THF), a common solvent, and furan itself. Importers should note the varying duty rates: the UK applies a 6.00% ad valorem duty, the EU a 6.50% ad valorem duty, and the US a 3.7% ad valorem rate under the Most Favored Nation (MFN) column. Significant trade considerations for the US include numerous preferential duty programs (e.g., A, AU, CL, KR) offering "Free" duty, and a 25% ad valorem rate for goods from non-MFN countries. Customs brokers must verify origin to leverage these preferential rates, ensuring accurate classification and compliance with WCO General Interpretive Rules.

How to Classify This HS Code?
What products does HS 293211 cover?
This subheading covers tetrahydrofuran (THF), a heterocyclic organic compound specifically characterized by a fully hydrogenated furan ring within its molecular structure. As defined by the World Customs Organization's Harmonized System Nomenclature and reflected in national tariffs like the USITC Harmonized Tariff Schedule (HTSUS) and the EU TARIC, this classification is precise. THF is a colorless, water-miscible organic liquid with a low viscosity, primarily used as a solvent in various industrial applications, including the production of polymers, particularly polytetramethylene ether glycol (PTMEG), and as a reaction solvent for Grignard reagents and other organometallic compounds. Its classification here is contingent on its specific chemical identity as tetrahydrofuran, distinct from other furan derivatives.
What falls outside HS 293211?
The following products are excluded from HS 293211: furan itself (unhydrogenated), which is classified under HS 293219 as "Other compounds containing an unfused furan ring (whether or not hydrogenated) in the structure." Additionally, derivatives of furan or tetrahydrofuran that contain other functional groups of Chapter 29, such as alcohols, ethers, or ketones, would generally be classified under more specific subheadings within Chapter 29 according to the "most specific description" principle (GRI 6, read in conjunction with GRI 3(a)). For example, 2-furaldehyde (furfural) is classified under HS 293213, and furan-2-carboxylic acid is classified under HS 293219, as they are not tetrahydrofuran.
What are common classification mistakes for HS 293211?
A common error is misclassifying other furan derivatives, particularly furan itself or its partially hydrogenated forms, into HS 293211, which is exclusively for tetrahydrofuran. Importers sometimes overlook the "tetrahydro" prefix, which denotes complete hydrogenation of the furan ring, leading to incorrect declarations. Another mistake involves classifying mixtures containing tetrahydrofuran under this subheading when the mixture's essential character is imparted by another component, or when the THF is merely a solvent for a product classified elsewhere. Such errors can result in incorrect duty assessments and potential penalties. Proper application of General Interpretative Rule (GRI) 1, which states that classification is determined according to the terms of the headings and any relative section or chapter notes, is crucial.
How should importers classify products under HS 293211?
The correct procedure for classifying products under HS 293211 requires meticulous attention to the chemical identity of the substance. Importers and customs brokers must first confirm that the product is indeed tetrahydrofuran, meaning it possesses a fully hydrogenated furan ring and no other principal functional groups that would dictate classification elsewhere in Chapter 29. This confirmation often involves reviewing the Chemical Abstracts Service (CAS) number (e.g., 109-99-9 for THF), chemical name, and structural formula. Consulting safety data sheets (SDS) and certificates of analysis (CoA) is essential for verifying the precise chemical composition and purity. If any doubt exists, seeking a binding ruling from the relevant customs authority (e.g., CBP in the US, national customs authorities in the EU) is highly recommended to ensure compliance and avoid potential classification disputes.

FAQ
What is the Most Favored Nation (MFN) import duty rate for products classified under HS 2932.11 in the United States?
For products classified under Harmonized System (HS) subheading 2932.11, which covers 'Compounds containing an unfused furan ring (whether or not hydrogenated) in the structure,' the Most Favored Nation (MFN) duty rate in the United States is 3.7% ad valorem. This rate applies to goods from countries that do not have a specific preferential trade agreement with the U.S. or are not subject to special trade programs. Importers should always verify the current rates via the United States International Trade Commission (USITC) Harmonized Tariff Schedule (HTS) for the most up-to-date information.
Are there any preferential duty rates available for HS 2932.11, and which trade agreements offer them?
Yes, preferential duty rates, including 'Free' (0% ad valorem), are available for HS 2932.11 under various U.S. free trade agreements and preference programs. For example, goods originating from countries such as Australia (AU), Bahrain (BH), Chile (CL), Colombia (CO), Israel (IL), Jordan (JO), Korea (KR), Morocco (MA), Oman (OM), Panama (PA), Peru (PE), and Singapore (SG) may be eligible for duty-free treatment upon meeting the respective rules of origin. Additionally, programs like the Generalized System of Preferences (GSP) or agreements with Canada and Mexico (USMCA) could offer preferential treatment. Importers must ensure they meet all origin requirements and provide proper documentation, such as a certificate of origin, to claim these preferential rates. Consult the specific trade agreement's text and the USITC HTS for detailed eligibility criteria.
What are the key classification criteria for determining if a chemical compound falls under HS 2932.11?
The primary classification criterion for HS 2932.11 is the presence of an 'unfused furan ring' in the chemical structure. This means the furan ring must not be fused with other ring systems (e.g., benzene, pyridine) within the same molecule. The subheading also specifies 'whether or not hydrogenated,' indicating that tetrahydrofuran derivatives, as long as the furan ring remains unfused, would also be classified here. Importers and customs brokers should meticulously review the chemical structure of the compound against the Explanatory Notes to Chapter 29 of the Harmonized System, published by the World Customs Organization (WCO), for precise guidance. Laboratory analysis or a detailed chemical abstract service (CAS) number description can aid in accurate classification.
What documentation is typically required for importing chemicals classified under HS 2932.11?
For importing chemicals under HS 2932.11, standard import documentation includes a commercial invoice, packing list, and bill of lading or air waybill. Additionally, a Safety Data Sheet (SDS) is often required by regulatory agencies (e.g., EPA in the U.S.) to ensure safe handling and provide hazard information. If claiming preferential duty rates, a valid Certificate of Origin (e.g., USMCA Certificate of Origin, Free Trade Agreement Certificate) is mandatory. Depending on the specific chemical and its end-use, other permits or declarations from agencies like the Environmental Protection Agency (EPA) or the Food and Drug Administration (FDA) might be necessary. Importers should consult with a licensed customs broker and review relevant agency regulations prior to importation.
Could different countries apply varying duty rates for HS 2932.11, and how can I verify them?
Yes, duty rates for HS 2932.11 can vary significantly between different importing countries, even for the same product. While the HS code structure is harmonized internationally at the 6-digit level, individual countries set their own national tariff rates and implement distinct trade agreements. For example, while the U.S. MFN rate is 3.7%, other countries might apply rates like 6.00%, 6.50%, or 25% for non-preferential imports. To verify the exact duty rates for a specific destination country, importers should consult that country's official customs tariff schedule. Examples include the EU TARIC database for European Union member states or the UK Trade Tariff for the United Kingdom. Always use the official government source for the most accurate and current information.
