Magnesia Carbon Bricks — China — C-570-955

A measure titled “Magnesia Carbon Bricks” concerns certain refractory bricks made with magnesia and carbon. These products are used to line high-temperature industrial equipment, such as furnaces. The exact products covered are defined by the measure’s written scope, including technical descriptions and possible exclusions—not by the title alone.

“AD/CVD” means antidumping and countervailing duties. Antidumping duties (AD) may apply when merchandise is sold in the United States at less than normal value. Countervailing duties (CVD) may apply when foreign-government subsidies benefit the merchandise. These measures typically affect importers, foreign producers or exporters, and U.S. purchasers bringing covered merchandise into the United States. An importer may need to provide accurate entry information, pay required cash deposits, and later face a duty assessment if the final liability differs.

Classification under the Harmonized Tariff Schedule (HTS) helps identify potentially relevant merchandise, but an HTS number alone does not decide whether the product is covered. Importers should compare the product’s composition, physical characteristics, dimensions, use, and manufacturing details with the official scope. When the match is uncertain, a customs broker or trade-counsel review—and, where appropriate, a formal scope inquiry—may be necessary.

What to check

• Read the official measure’s scope and exclusions; do not rely only on the product title or HTS number.
• Confirm the brick’s composition, grade, dimensions, shape, intended use, and manufacturing process against the scope description.
• Identify the country of origin, producer, and exporter, because AD/CVD treatment can depend on these facts and on applicable company-specific information.
• Ask your customs broker to verify the correct HTS classification, entry requirements, and any applicable cash-deposit instructions before importation.
• Keep product specifications, supplier declarations, invoices, origin records, and prior scope analyses so you can support the entry and respond to questions.
