Potassium Phosphate Salts — China — C-570-963

“Potassium Phosphate Salts” describes a product category involving phosphate compounds containing potassium. An AD/CVD measure combines two trade-remedy programs: antidumping (AD), which addresses imports sold at less than normal value, and countervailing duties (CVD), which address benefits from government subsidies. The exact products covered are defined by the measure’s written scope, not just by the product name.

These measures typically affect US importers, foreign producers and exporters, and sometimes related parties involved in the supply chain. An importer may need to pay additional duties, provide accurate entry information, and comply with special certification or reporting requirements. The tariff classification, country of origin, producer or exporter identity, product specifications, and scope language should all be reviewed; an HTS classification can help identify a possible measure but does not by itself decide whether the product is covered. When the scope is unclear, seek guidance from a customs broker or trade-remedy professional and consider whether an official scope inquiry is appropriate.

What to check

• Read the measure’s full scope and exclusions, and compare them with the product’s chemical composition, physical form, purity, packaging, and intended use.
• Confirm the product’s HTS classification, country of origin, manufacturer, producer, and exporter; do not rely on the tariff number alone.
• Ask your supplier for complete production and shipping information, including whether the goods were made by one company and exported by another.
• Check the applicable AD/CVD instructions for entry documentation, cash-deposit treatment, importer certifications, and later duty assessment.
• Keep technical specifications, purchase records, origin documents, and communications supporting your coverage analysis, and obtain broker or counsel advice if the scope is ambiguous.
