HS 290344 Pentafluoroethane (HFC-125), 1,1,1-trifluoroethane (HFC-143a) and 1,1,2-trifluoroethane (HFC-143)

The MFN import duty rates for products classified under HS 2903.44 (Pentafluoroethane (HFC-125), 1,1,1-trifluoroethane (HFC-143a) and 1,1,2-trifluoroethane (HFC-143)) typically range. For example, the United States applies a 3.7% ad valorem duty rate under the Harmonized Tariff Schedule of the United States (HTSUS) for this subheading. The European Union's TARIC database shows a 5.5% ad valorem duty rate for these products. The UK Global Tariff also lists a 5.5% ad valorem duty. Importers should always verify the current MFN rate with the specific customs authority of the importing country, as rates can be subject to change based on national legislation or international agreements.

Yes, preferential duty rates are often available for HS 2903.44 depending on the country of origin and applicable free trade agreements (FTAs). For instance, under various US FTAs, products originating from countries such as Australia (AU), Bahrain (BH), Chile (CL), Colombia (CO), Israel (IL), Korea (KR), Panama (PA), Peru (PE), and Singapore (SG) may qualify for a 'Free' duty rate. Similarly, the EU has preferential agreements that could reduce or eliminate duties for originating goods. Importers should consult the specific trade agreement's rules of origin and provide appropriate documentation (e.g., a certificate of origin) to claim preferential treatment. Failure to meet the rules of origin will result in the application of the MFN rate.

Classification under HS 2903.44 is strictly based on the chemical identity of the product. This subheading specifically covers 'Pentafluoroethane (HFC-125)', '1,1,1-trifluoroethane (HFC-143a)', and '1,1,2-trifluoroethane (HFC-143)'. These are defined by their precise chemical structure and empirical formulas (e.g., C2HF5 for HFC-125, C2H3F3 for HFC-143a and HFC-143). Importers must ensure that the product's chemical name and CAS number (if applicable) precisely match one of these listed compounds. Mixtures containing these substances, or isomers not explicitly named, would typically be classified elsewhere, often under other subheadings within Chapter 29 or Chapter 38, depending on their composition and intended use. Accurate chemical analysis and product specifications are crucial for correct classification.

Standard import documentation for goods under HS 2903.44 includes a commercial invoice, packing list, bill of lading or air waybill, and a certificate of origin if preferential duty rates are claimed. Due to the nature of these chemicals, additional documentation may be required. This could include a Safety Data Sheet (SDS) for hazardous material handling and transportation compliance, and potentially permits or licenses from environmental agencies (e.g., EPA in the US, ECHA in the EU) if the substances are subject to regulations concerning ozone-depleting substances or fluorinated greenhouse gases, even though HFCs are not ozone-depleting, they are potent greenhouse gases. Importers should verify specific national requirements, as these can vary significantly by country.

Yes, while HFCs (including HFC-125, HFC-143a, and HFC-143) are not ozone-depleting substances and thus not controlled by the Montreal Protocol for ozone depletion, they are potent greenhouse gases. Consequently, their production, consumption, and trade are subject to controls under the Kigali Amendment to the Montreal Protocol. Many countries have implemented national regulations to phase down HFCs in line with this amendment. For example, the EU has the F-Gas Regulation (EU) No 517/2014, which imposes quotas and reporting requirements on HFC imports. The US is also implementing an HFC phasedown under the American Innovation and Manufacturing (AIM) Act. Importers must be aware of these regulations, which may include quota allocations, licensing requirements, and strict reporting obligations. Non-compliance can result in significant penalties.
