HS 293530 N-Ethyl-N-(2-hydroxyethyl) perfluorooctane sulphonamide
Quick Answer: HS code 293530 covers N-Ethyl-N-(2-hydroxyethyl) perfluorooctane sulphonamide, a specific per- and polyfluoroalkyl substance (PFAS) derivative. This synthetic organic compound is primarily used as an intermediate in the production of various fluorochemicals, including surfactants, water and oil repellents, and fire-fighting foams. Importers and exporters should be aware of the varying duty rates: the UK applies a 6.00% ad valorem rate, while the EU's TARIC system shows 6.50%. In the US, the general rate is 6.5%, but many preferential trade agreements (e.g., A+, AU, CL, KR, SG) offer duty-free entry. Notably, due to its PFAS classification, this product may be subject to evolving environmental regulations and restrictions globally, impacting trade compliance and market access.

How to Classify This HS Code?
What products does HS 293530 cover?
This subheading covers N-Ethyl-N-(2-hydroxyethyl) perfluorooctane sulphonamide, a specific chemical compound defined by its precise chemical structure. As per the Harmonized System Nomenclature, specifically Chapter 29, which covers organic chemicals, and Heading 2935, which encompasses sulfonamides, this particular compound is uniquely identified. The USITC Harmonized Tariff Schedule (HTS) and the EU TARIC system both align with this WCO definition, ensuring consistent global classification for this distinct perfluorinated sulfonamide derivative, primarily used as an intermediate in the production of various fluorochemicals and surfactants.
What falls outside HS 293530?
The following products are excluded from HS 293530: other sulfonamides not possessing the exact N-Ethyl-N-(2-hydroxyethyl) perfluorooctane sulphonamide structure. For instance, perfluorooctane sulfonic acid (PFOS) itself, or its salts and derivatives that do not match the specific chemical formula of the subheading, would be classified elsewhere, often under other subheadings within 2935 or even different headings depending on their precise chemical nature. Similarly, mixtures containing this compound, where it is not the sole or principal constituent, might fall under different headings, such as Chapter 38 for miscellaneous chemical products, if they constitute prepared mixtures.
What are common classification mistakes for HS 293530?
A common error is misclassifying similar perfluorinated compounds or other sulfonamides under HS 293530 without verifying the exact chemical structure. Importers sometimes incorrectly assume that any perfluorooctane sulfonamide derivative belongs here, neglecting the specific N-Ethyl-N-(2-hydroxyethyl) substitution required. This often violates General Interpretative Rule (GRI) 1, which mandates classification according to the terms of the headings and any relative section or chapter notes. Another mistake involves classifying mixtures where N-Ethyl-N-(2-hydroxyethyl) perfluorooctane sulphonamide is present but not the predominant component, potentially leading to incorrect classification under Heading 2935 instead of a more appropriate heading for mixtures.
How should importers classify products under HS 293530?
The correct procedure for classifying products under HS 293530 involves a meticulous review of the chemical's Certificate of Analysis (CoA) or Material Safety Data Sheet (MSDS) to confirm its precise chemical name and structure, specifically N-Ethyl-N-(2-hydroxyethyl) perfluorooctane sulphonamide. Importers and customs brokers should cross-reference this information with the WCO Harmonized System Explanatory Notes for Chapter 29 and Heading 2935, alongside the specific national tariff schedules like the USITC HTS or EU TARIC. If there is any doubt regarding the exact chemical identity, obtaining a binding ruling from the relevant customs authority (e.g., CBP in the US) is highly recommended to ensure compliance and avoid potential penalties for misclassification.

FAQ
What is the Most Favored Nation (MFN) import duty rate for HS code 293530, 'N-Ethyl-N-(2-hydroxyethyl) perfluorooctane sulphonamide', in key markets?
The MFN (Most Favored Nation) import duty rates for HS code 293530 vary by importing country. For example, the United States generally applies a duty rate of 6.5% ad valorem. The European Union's TARIC database indicates a common customs tariff duty rate of 6.5% ad valorem. The UK Global Tariff also lists a 6.5% ad valorem rate. Importers should always consult the specific tariff schedule of the destination country for the most current and accurate MFN rate, as these are subject to change based on national legislation and WCO recommendations.
Are there any preferential duty programs or free trade agreements that offer reduced or zero duties for 'N-Ethyl-N-(2-hydroxyethyl) perfluorooctane sulphonamide' under HS 293530?
Yes, many countries offer preferential duty treatment for HS 293530 under various free trade agreements (FTAs) or special programs. For instance, the United States grants duty-free access (0% ad valorem) for imports from countries eligible under programs such as A+ (Generalized System of Preferences for Least Developed Beneficiary Developing Countries), AU (Australia FTA), BH (Bahrain FTA), CL (Chile FTA), CO (Colombia TPA), D (Dominican Republic-Central America-United States Free Trade Agreement - CAFTA-DR), E (Andean Trade Preference Act), IL (Israel FTA), JO (Jordan FTA), KR (Korea FTA), MA (Morocco FTA), OM (Oman FTA), P (Panama TPA), PA (Panama TPA), PE (Peru TPA), S (Singapore FTA), and SG (Singapore FTA). Importers must ensure they meet the specific Rules of Origin criteria for the respective agreement and provide proper documentation (e.g., a certificate of origin) to claim preferential rates.
What are the key classification criteria for 'N-Ethyl-N-(2-hydroxyethyl) perfluorooctane sulphonamide' under HS 293530, and what are common classification pitfalls?
HS 293530 specifically covers 'N-Ethyl-N-(2-hydroxyethyl) perfluorooctane sulphonamide'. The primary classification criterion is the precise chemical structure and identity of the compound. Chapter 29 of the Harmonized System covers 'Organic chemicals', and heading 2935 specifically includes 'Sulphonamides'. The subheadings further delineate based on specific chemical names or groups. Common classification pitfalls include misidentifying the exact chemical name, confusing it with other perfluorinated compounds or sulphonamides, or failing to accurately represent the purity or isomeric form if relevant. Importers should have a detailed chemical analysis or certificate of analysis (CoA) available to substantiate the classification, aligning with the WCO Explanatory Notes for Chapter 29.
What documentation is typically required by customs authorities for the import of 'N-Ethyl-N-(2-hydroxyethyl) perfluorooctane sulphonamide' under HS 293530?
Standard import documentation for HS 293530 includes a commercial invoice, packing list, bill of lading or air waybill, and a customs declaration form. Additionally, due to the nature of organic chemicals, customs authorities may require a Certificate of Analysis (CoA) or Material Safety Data Sheet (MSDS) to verify the chemical identity, purity, and safety information. If claiming preferential duty rates under a free trade agreement, a valid Certificate of Origin (e.g., NAFTA Certificate of Origin, EUR.1 movement certificate) is mandatory. Importers should also be aware of any specific national chemical control regulations or import licensing requirements that may apply to perfluorinated compounds in the destination country.
Are there any specific trade restrictions or regulatory considerations for 'N-Ethyl-N-(2-hydroxyethyl) perfluorooctane sulphonamide' (HS 293530) due to its perfluorinated nature?
Yes, 'N-Ethyl-N-(2-hydroxyethyl) perfluorooctane sulphonamide' is a perfluorooctane sulphonamide (PFOS-related substance). PFOS and its derivatives are recognized as persistent organic pollutants (POPs) and are subject to international control under the Stockholm Convention on Persistent Organic Pollutants. Many countries have implemented national regulations to restrict or ban the production, use, import, and export of PFOS and PFOS-related substances. Importers must verify the specific regulations in both the exporting and importing countries, as these can include outright bans, strict quantity limits, or requirements for specific permits or exemptions. Failure to comply can result in severe penalties, including seizure of goods and fines. Consultation with a customs broker specializing in chemical imports is highly recommended.
