1,1,1,2-Tetrafluoroethane (R-134a) — China — A-570-044

This is an antidumping and countervailing duty (AD/CVD) trade measure concerning 1,1,1,2-Tetrafluoroethane, commonly called R-134a, a refrigerant. Antidumping duties address imports that an investigating authority determines are sold at less than fair value. Countervailing duties address benefits, or subsidies, provided by a foreign government to producers or exporters. An AD/CVD measure may include one or both types of duties, depending on the official order and findings.

The measure typically affects importers, manufacturers, distributors, and other parties bringing covered R-134a into the United States from specified countries or sources. It matters because AD/CVD obligations are generally separate from ordinary customs duty and may require additional cash deposits, documentation, and reporting. Coverage depends on the legal product description, country of origin, and other scope details—not merely the product name or tariff classification. Importers should have a customs broker or trade attorney review uncertain cases.

What to check

• Read the official scope language and compare it with the product’s chemical identity, purity, packaging, and intended use; do not rely on the product name alone.
• Confirm the country of origin and the identity of the manufacturer and exporter, because AD/CVD treatment can vary by country and company.
• Check the applicable HTS classification, while understanding that an HTS number is generally an entry aid and does not by itself determine whether the product is covered.
• Ask your customs broker how to report the entry and whether additional AD/CVD cash-deposit, bond, or certification requirements apply.
• Keep purchase records, technical specifications, origin documents, and supplier statements, and obtain professional advice if the product may fall near the scope boundaries.
