Sol Gel Alumina-Based Ceramic Abrasive Grains — China — C-570-191

This is an antidumping and countervailing duty (AD/CVD) trade measure concerning certain sol-gel alumina-based ceramic abrasive grains. These are engineered abrasive materials made with an alumina ceramic process and used in products such as abrasive wheels, belts, discs, or other grinding and finishing tools. The measure may apply based on the product’s physical characteristics and manufacturing process, not simply on its brand name or intended use.

Antidumping duties address imports sold at less than fair value, while countervailing duties address benefits provided by a foreign government that support exported goods. An importer may be responsible for declaring the correct tariff classification, reporting the relevant country of origin, and paying any applicable AD/CVD deposits or duties. Coverage is determined by the measure’s scope and official product descriptions; a customs broker or trade specialist may be needed for close classification or scope questions.

What to check

• Compare the product’s composition, grain form, manufacturing process, and specifications with the official scope language—not just the commercial product name.
• Confirm the HTSUS classification, country of origin, and manufacturer or exporter details before entry; do not assume the tariff code alone determines coverage.
• Check official AD/CVD instructions for the applicable case, including deposit requirements, certification or reporting rules, and how scope questions must be submitted.
• Ask the supplier for technical data, production records, and origin documentation that can support a scope and classification review.
• Obtain customs-broker or trade-counsel advice when the product is blended, further processed, imported through another country, or only arguably within the scope.
