Melamine In Crystal Form — Japan — A-588-056

“Melamine in crystal form” refers to a chemical product identified by its physical form and product characteristics. An AD/CVD measure means antidumping and countervailing duties may apply: antidumping (AD) addresses sales from a foreign country at less than fair value, while countervailing duties (CVD) address certain foreign government subsidies. These are trade-remedy duties, separate from ordinary customs duty.

The measure typically affects importers bringing the covered melamine product into the United States from the countries and producers or exporters identified in the official measure. The key issue is the legal product scope—not just the product name or tariff classification. An importer may be responsible for additional duties, entry documentation, and later duty adjustments, so a customs broker or trade counsel may be needed when scope is unclear.

What to check

• Read the official scope language and compare the product’s chemical composition, physical form, grade, and intended use; do not rely on the product name alone.
• Confirm the country of origin, manufacturer, exporter, and any applicable exclusions or scope rulings before importing.
• Use the listed HTSUS classification as a screening tool, but remember that classification alone does not determine whether the product is covered.
• Ask your customs broker to verify the required AD/CVD entry information, cash-deposit treatment, and importer obligations for the shipment.
• Keep product specifications, invoices, origin records, and supplier information, and seek a formal scope or professional customs determination if the product is borderline.
