Pentafluoroethane (R-125) — China — C-570-138

An AD/CVD measure concerns trade-remedy duties. “AD” means antidumping: the government may impose an additional duty when imported merchandise is sold in the United States at less than normal value and causes, or threatens, injury to a domestic industry. “CVD” means countervailing duty: an additional duty may apply when imported merchandise benefits from certain government subsidies and harms a domestic industry. These duties are separate from ordinary customs duty and may apply even when the regular tariff rate is low or zero.

A measure titled or based on “Pentafluoroethane (R-125)” generally requires checking whether the imported product falls within the legal product scope, rather than relying only on its commercial name or tariff classification. It can typically affect manufacturers, exporters, importers, distributors, and downstream businesses bringing the covered chemical into the United States. The applicable treatment may depend on the product’s physical characteristics, country of origin, manufacturer or exporter, entry date, and the specific AD/CVD instructions in force. Importers should confirm the scope and current entry requirements with official government sources or a qualified customs broker or trade-remedy specialist.

What to check

• Read the official scope language and compare the product’s composition, purity, packaging, and intended use; do not rely on the product name alone.
• Confirm the product’s tariff classification, country of origin, manufacturer, and exporter. An HTSUS number helps identify merchandise but does not by itself decide AD/CVD coverage.
• Check current Customs and Border Protection instructions for the required cash deposit, entry documentation, and any special reporting or certification requirements; do not assume the ordinary duty rate is the only amount due.
• Ask the supplier for consistent records identifying the manufacturer, exporter, composition, and origin, and reconcile those details with commercial invoices, packing lists, and entry data.
• Have a customs broker or trade-remedy professional review uncertain scope questions before importation, because scope interpretation and company-specific treatment can require specialized judgment.
