HS 290374 Chlorodifluoroethanes (HCFC-142, 142b)

The MFN (Most Favored Nation) import duty rates for Chlorodifluoroethanes under HS 2903.74 can vary significantly by importing country. Common MFN rates observed globally include 4.0% ad valorem, 5.5% ad valorem, and 3.7% ad valorem. For example, the United States applies a specific MFN duty rate for this subheading, as published by the US International Trade Commission (USITC). Importers should consult the specific tariff schedule of the destination country, such as the Harmonized Tariff Schedule of the United States (HTSUS) or the EU TARIC database, for the precise and current MFN rate applicable.

Yes, preferential duty rates, including duty-free treatment, are frequently available for Chlorodifluoroethanes (HS 2903.74) under various Free Trade Agreements (FTAs) and special programs. For instance, goods originating from countries like Australia (AU), Bahrain (BH), Chile (CL), Colombia (CO), Israel (IL), Jordan (JO), Korea (KR), Morocco (MA), Oman (OM), Panama (PA), Peru (PE), Singapore (SG), and others may qualify for duty-free entry into certain markets, such as the United States, provided all rules of origin requirements are met. Importers must ensure they have the necessary documentation, such as a Certificate of Origin, to claim these preferential rates. Always verify the specific FTA and its origin criteria relevant to your trade lane.

HS 2903.74 specifically covers 'Chlorodifluoroethanes,' which includes isomers such as HCFC-142 and HCFC-142b. The primary classification criterion is the chemical composition: a saturated acyclic hydrocarbon derivative containing both chlorine and fluorine atoms, with an ethane backbone. Proper classification relies on the chemical name and structure. Importers should reference the World Customs Organization (WCO) Explanatory Notes for Chapter 29, which provide detailed guidance on the classification of organic chemicals. Laboratory analysis or a Certificate of Analysis (CoA) from the manufacturer confirming the specific chemical identity (e.g., 1,1-dichloro-1-fluoroethane or 1-chloro-1,1-difluoroethane) is often crucial for accurate classification.

Beyond standard import documentation (commercial invoice, packing list, bill of lading/air waybill), the importation of Chlorodifluoroethanes (HS 2903.74) often requires additional documentation due to their status as Hydrochlorofluorocarbons (HCFCs), which are ozone-depleting substances. Importers may need to provide permits or licenses issued by environmental protection agencies (e.g., the U.S. Environmental Protection Agency - EPA, or equivalent bodies in other countries) demonstrating compliance with international agreements like the Montreal Protocol. This can include import quotas, usage certifications, or declarations of intent for specific applications (e.g., feedstock). Customs brokers should verify national environmental regulations and permit requirements well in advance of shipment.

While not universally applied, Chlorodifluoroethanes (HS 2903.74) can, in certain circumstances and from specific countries of origin, be subject to additional duties such as anti-dumping duties (ADD) or countervailing duties (CVD). These duties are imposed to counteract unfair trade practices. Importers must regularly check the trade remedies databases of the importing country (e.g., the U.S. Department of Commerce's Enforcement and Compliance website, the EU's Anti-Dumping and Anti-Subsidy Measures database, or the UK Trade Tariff) to determine if any such measures are in effect for their specific product and country of origin. Failure to account for these can result in significant unforeseen costs and penalties.
