HS 290341 Saturated fluorinated derivatives of acyclic hydrocarbons
Quick Answer: HS code 2903.41 covers saturated fluorinated derivatives of acyclic hydrocarbons, primarily encompassing compounds like 1,1,1,2-tetrafluoroethane (HFC-134a), a widely used refrigerant. These are organic chemicals where hydrogen atoms in an acyclic hydrocarbon chain have been replaced by fluorine atoms, and all carbon-carbon bonds are single bonds. For importers and exporters, understanding the varying duty rates is crucial. The UK applies a 4.00% ad valorem duty. The EU imposes a 5.50% ad valorem duty. In the US, the general duty rate is 3.7% ad valorem, but significant preferential rates, including "Free," apply under various trade agreements (e.g., with Australia, Chile, Korea, Singapore). A 25% duty rate may apply under specific trade measures. Importers should verify eligibility for preferential tariffs to optimize costs.

How to Classify This HS Code?
What products does HS 290341 cover?
This subheading covers saturated fluorinated derivatives of acyclic hydrocarbons, which are organic chemical compounds where all carbon-carbon bonds are single bonds and hydrogen atoms have been replaced, in whole or in part, by fluorine atoms. These compounds are typically characterized by their high stability and unique physical properties, making them valuable in various industrial applications. Examples include perfluorocarbons (PFCs) like perfluoromethane (CF4) and perfluoroethane (C2F6), provided they are saturated. The scope is defined by the World Customs Organization's Harmonized System Nomenclature and further elaborated in national tariffs such as the USITC Harmonized Tariff Schedule of the United States (HTSUS) and the EU TARIC system, ensuring consistent global application for these specific chemical structures.
What falls outside HS 290341?
The following products are excluded from HS 290341: unsaturated fluorinated derivatives, such as those containing double or triple carbon-carbon bonds, which would fall under other subheadings within Heading 2903 (e.g., 2903.42 for unsaturated fluorinated derivatives). Additionally, cyclic fluorinated hydrocarbons are excluded, as this subheading specifically targets acyclic compounds. Halogenated derivatives containing halogens other than fluorine (e.g., chlorine, bromine, iodine) are also excluded unless fluorine is the predominant halogen and the compound is saturated and acyclic. Mixtures of these compounds, if they do not predominantly consist of saturated fluorinated acyclic hydrocarbons, may also be classified elsewhere, potentially under mixtures of chemicals or specific functionalized derivatives.
What are common classification mistakes for HS 290341?
A common error is misclassifying unsaturated fluorinated derivatives, such as hexafluoropropene, into HS 290341, despite the clear "saturated" descriptor in the subheading text. Importers sometimes overlook the distinction between saturated and unsaturated compounds, leading to incorrect classification. Another frequent mistake involves compounds that contain other halogens in addition to fluorine; if the compound is not exclusively fluorinated or predominantly fluorinated with fluorine being the primary halogen, it may belong elsewhere within Heading 2903 or even Chapter 29. Failure to apply General Interpretative Rule (GRI) 1, which dictates classification according to the terms of the headings and any relative section or chapter notes, often contributes to these errors, particularly regarding the "saturated" and "acyclic" criteria.
How should importers classify products under HS 290341?
The correct procedure for classifying products under HS 290341 involves a meticulous review of the chemical structure to confirm it is an acyclic hydrocarbon and that all carbon-carbon bonds are single bonds (saturated). Importers and customs brokers must verify that fluorine is the sole or predominant halogen substituent. It is crucial to consult the WCO Explanatory Notes for Heading 2903 and any specific rulings from national customs authorities like the US Customs and Border Protection (CBP) or EU member states. Obtaining a Certificate of Analysis or a detailed chemical specification sheet from the manufacturer is highly recommended to confirm the saturation and acyclic nature of the compound, ensuring compliance with GRI 1 and accurate duty assessment.

FAQ
What are the typical Most Favored Nation (MFN) import duty rates for products classified under HS 2903.41, 'Saturated fluorinated derivatives of acyclic hydrocarbons'?
The MFN (Most Favored Nation) import duty rates for HS 2903.41 generally range. For example, the United States imposes an MFN duty rate of 4.0% ad valorem. The European Union's TARIC database indicates an MFN duty rate of 5.5% ad valorem for this heading. Importers should always consult the specific tariff schedule of the importing country (e.g., USITC Harmonized Tariff Schedule, EU TARIC) for the most current and accurate MFN rates, as these can be subject to change.
Are there any preferential duty rates available for HS 2903.41 under common Free Trade Agreements (FTAs) or special programs?
Yes, preferential duty rates, including 'Free' (0% ad valorem), are frequently available for HS 2903.41 under various Free Trade Agreements (FTAs) and special trade programs, provided the goods meet the respective Rules of Origin. For instance, the United States offers duty-free treatment for eligible goods 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) under their respective FTAs. Similarly, within the European Union, goods originating from countries with preferential agreements (e.g., under GSP or specific FTAs) may also qualify for reduced or zero duties. Importers must ensure they have the necessary documentation, such as a Certificate of Origin, to claim these preferential rates.
What are the key classification criteria for 'Saturated fluorinated derivatives of acyclic hydrocarbons' under HS 2903.41?
HS 2903.41 specifically covers 'Saturated fluorinated derivatives of acyclic hydrocarbons'. The primary classification criteria are: 1. Saturation: The hydrocarbon chain must be saturated (i.e., contain only single carbon-carbon bonds). 2. Fluorination: The derivative must contain fluorine atoms. 3. Acyclic: The hydrocarbon structure must be open-chain, not cyclic. This heading typically includes compounds like perfluorocarbons (PFCs) that are fully fluorinated and saturated acyclic hydrocarbons. It's crucial to distinguish these from unsaturated fluorinated derivatives (e.g., HS 2903.42) or cyclic fluorinated derivatives (e.g., HS 2903.99). The chemical structure and functional groups are paramount for accurate classification, referencing the Explanatory Notes to the Harmonized System for detailed guidance.
What specific documentation is typically required by customs authorities when importing goods classified under HS 2903.41?
When importing goods under HS 2903.41, standard customs documentation includes a commercial invoice, packing list, and bill of lading or air waybill. To claim preferential duty rates (e.g., 'Free' under an FTA), a valid Certificate of Origin (e.g., Form A, FTA-specific certificate) is mandatory, demonstrating that the goods meet the origin requirements of the respective agreement. Additionally, depending on the specific chemical and its end-use, importers may need to provide safety data sheets (SDS) and comply with chemical control regulations (e.g., TSCA in the US, REACH in the EU), which might require specific declarations or permits from environmental or chemical regulatory agencies. Customs brokers should verify any additional country-specific import licensing or registration requirements.
Are there any specific trade restrictions or regulatory considerations for 'Saturated fluorinated derivatives of acyclic hydrocarbons' under HS 2903.41?
Yes, certain saturated fluorinated derivatives of acyclic hydrocarbons, particularly perfluorocarbons (PFCs), are recognized as potent greenhouse gases. Consequently, their production, use, and trade may be subject to international environmental agreements like the Kyoto Protocol and domestic regulations aimed at controlling emissions. While HS 2903.41 itself is a classification code, the specific chemical compounds within this heading might fall under national environmental protection agency (EPA) regulations, requiring reporting or restrictions on their release. Importers should verify if the specific chemical substance is listed under any controlled substances acts or environmental regulations in the importing country, which could impact import eligibility, require specific permits, or necessitate additional reporting post-importation.
