Pentafluoroethane (R-125) — China — A-570-137

This is an antidumping and countervailing duty (AD/CVD) trade measure concerning pentafluoroethane, commonly known as R-125, a refrigerant or refrigerant component. Antidumping (AD) duties address imports that are sold in the United States at less than fair value; countervailing (CVD) duties address benefits that a foreign government provides to producers or exporters. These are separate from ordinary customs duty and may apply in addition to it.

The measure typically affects importers bringing covered R-125 into the United States, as well as foreign producers, exporters, and sometimes related products or mixtures depending on the legal product description. The key issue is scope: a product’s name, chemical composition, form, packaging, origin, producer, and tariff classification may all matter. An importer may need to pay cash deposits at entry and later face a final duty assessment, so classification and scope should be verified with official sources or a customs professional.

What to check

• Read the measure’s scope description, including chemical composition, mixtures, exclusions, and product forms; do not rely only on the product name.
• Confirm the product’s HTS classification, country of origin, manufacturer, and exporter, and understand that an HTS number alone may not decide scope.
• Check whether the entry requires AD/CVD cash deposits in addition to ordinary customs duties, and identify which agency instructions govern entry reporting.
• Keep contracts, invoices, technical data sheets, certificates of analysis, and origin records that support the product description and supply chain.
• Ask a customs broker or trade counsel to review borderline products, scope questions, and any potential importer-specific requirements.
