HS 292216 Diethanolammonium perfluorooctane sulphonate
Quick Answer: HS code 292216 specifically covers Diethanolammonium perfluorooctane sulphonate (DAPFOS), a chemical compound primarily used as a surfactant or in specialized applications. Importers and customs brokers should note the varying Most Favored Nation (MFN) duty rates: the UK applies a 6.00% ad valorem duty, the EU a 6.50% ad valorem duty, and the US a 6.5% ad valorem duty. For US imports, significant preferential duty treatment is available, with many Free Trade Agreement (FTA) partners qualifying for duty-free entry (e.g., under A, AU, CL, KR, SG provisions). Conversely, non-MFN rates, such as the US Column 2 rate of 30.5%, apply to goods from specific countries. Accurate classification is crucial to leverage preferential tariffs and ensure compliance.

How to Classify This HS Code?
What products does HS 292216 cover?
This subheading covers Diethanolammonium perfluorooctane sulphonate (CAS No. 70225-14-8), a specific chemical compound classified under Heading 2922 of the Harmonized System, which encompasses oxygen-function amino-compounds. According to the World Customs Organization (WCO) Harmonized System Nomenclature and further detailed in the USITC Harmonized Tariff Schedule (HTS) and EU TARIC, this particular salt of perfluorooctane sulfonic acid (PFOS) is precisely identified by its chemical structure and common name. It is primarily used as a surfactant, wetting agent, or in fire-fighting foams, and its classification here reflects its distinct chemical identity as an amino-alcohol salt of a sulfonic acid.
What falls outside HS 292216?
The following products are excluded from HS 292216: other salts of perfluorooctane sulfonic acid (PFOS), such as potassium perfluorooctane sulphonate, which would be classified under other subheadings within Chapter 29, typically 2904. Similarly, perfluorooctane sulfonic acid itself, in its free acid form, would fall under 2904. Additionally, mixtures containing diethanolammonium perfluorooctane sulphonate, where the chemical is not the sole or principal constituent and the mixture has a specific functional use, might be classified elsewhere, potentially in Chapter 34 for surface-active preparations or Chapter 38 for miscellaneous chemical products, depending on their composition and intended application.
What are common classification mistakes for HS 292216?
A common error is misclassifying other perfluorinated compounds or different salts of perfluorooctane sulfonic acid under HS 292216. Importers sometimes incorrectly assume that all PFOS-related substances belong here, overlooking the specific "Diethanolammonium" cation requirement. Another frequent mistake involves classifying mixtures containing this compound directly under 292216, rather than applying General Interpretative Rule (GRI) 3(b) for mixtures, which dictates classification by the component giving the mixture its essential character, or GRI 3(a) if it's a composite good. For instance, a fire-fighting foam concentrate where diethanolammonium perfluorooctane sulphonate is an ingredient would likely be classified under Chapter 38, specifically 3813.00, as a preparation.
How should importers classify products under HS 292216?
The correct procedure for classifying products under HS 292216 involves a meticulous review of the product's chemical name, CAS number, and precise chemical structure to confirm it is indeed "Diethanolammonium perfluorooctane sulphonate." Importers and customs brokers should first apply General Interpretative Rule 1, which states that classification is determined according to the terms of the headings and any relative section or chapter notes. Verify the product's purity; if it's a pure chemical, 292216 is likely correct. If it's a mixture, assess the essential character using GRI 3(b) to determine if the diethanolammonium perfluorooctane sulphonate imparts the essential character, or if it's a preparation for a specific use, which might lead to classification in another chapter, such as Chapter 34 or 38. Always cross-reference with official tariff schedules like the USITC HTS, EU TARIC, or UK Trade Tariff for specific national interpretations and duty rates, which for the US is 3.7% ad valorem, for the EU is 6.5% ad valorem, and for the UK is 6.5% ad valorem for Most Favoured Nation (MFN) rates.

What are the key classification criteria for Diethanolammonium perfluorooctane sulphonate under HS 2922.16?
HS 2922.16 specifically covers 'Diethanolammonium perfluorooctane sulphonate.' This classification falls under Chapter 29 of the Harmonized System, which deals with 'Organic chemicals.' More precisely, it is within heading 2922, which covers 'Oxygen-function amino-compounds.' The '16' subheading indicates a specific chemical compound within the broader category of amino-alcohols, other than those containing more than one type of oxygen function, and their ethers and esters; salts thereof. The chemical structure and specific name 'Diethanolammonium perfluorooctane sulphonate' are the primary determinants for its classification here. Customs authorities will verify the chemical identity and purity of the substance to confirm its correct classification.
What documentation is typically required for importing Diethanolammonium perfluorooctane sulphonate (HS 2922.16)?
Importers of Diethanolammonium perfluorooctane sulphonate (HS 2922.16) should be prepared to provide standard import documentation, which typically includes a commercial invoice, packing list, bill of lading or air waybill, and a customs declaration. To claim preferential duty rates under a free trade agreement, a valid certificate of origin or a declaration of origin is essential. Furthermore, as an organic chemical, a Safety Data Sheet (SDS) is often required for hazard communication and regulatory compliance, particularly for chemicals that may be subject to environmental or health regulations. Depending on the country, additional permits or licenses from chemical control agencies may also be necessary.
Are there any specific trade compliance considerations or restrictions for Diethanolammonium perfluorooctane sulphonate (HS 2922.16) due to its chemical nature?
Yes, Diethanolammonium perfluorooctane sulphonate is a per- and polyfluoroalkyl substance (PFAS) derivative. Due to growing environmental and health concerns regarding PFAS chemicals, many countries are implementing stricter regulations on their production, use, and importation. Importers should be aware of potential restrictions, reporting requirements, or outright bans on certain PFAS compounds. For example, some jurisdictions may require specific declarations, environmental impact assessments, or may have phased out the use of certain long-chain PFAS. It is crucial for importers to consult the latest chemical control regulations and environmental protection laws in both the exporting and importing countries to ensure full compliance and avoid potential penalties or shipment delays.
