Hexamine — China — C-570-181

“Hexamine” identifies the product covered by the trade measure, while “AD/CVD” means antidumping and countervailing duties. Antidumping (AD) duties address imports sold at less than fair value; countervailing (CVD) duties address benefits that a foreign government provides to producers or exporters. These duties are separate from ordinary customs duty and may apply in addition to it.

The measure typically affects importers bringing covered hexamine from specified countries or producers, as defined in the official product scope. Coverage depends on the merchandise description and may also involve tariff classification codes, but a code alone does not decide whether goods are covered. An importer may be responsible for declaring the correct measure information, paying any applicable additional duty, and keeping records that support the entry.

The main issue is scope: similar chemicals, blends, packaging, grades, or end uses may be treated differently under the official scope language. AD/CVD liability can also depend on the exporter, producer, country of origin, and the applicable cash-deposit or assessment instructions. When the facts are uncertain, obtain a customs broker’s or trade counsel’s review rather than relying only on a product name or tariff code.

What to check

• Read the official product scope and compare its technical description, composition, form, and packaging with the product being imported.
• Confirm the country of origin, exporter, and producer; do not assume the shipping country is the country of origin.
• Check the applicable HTS classification, but use it as a screening tool rather than as the sole basis for deciding coverage.
• Ask the supplier for complete product specifications and documentation, including manufacturing and origin information, and retain those records.
• Have a customs broker or trade counsel verify any uncertain scope, cash-deposit, entry-reporting, or certification requirements before importing.
