The U.S. Department of Commerce maintains an antidumping (AD) duty order, case number A-570-882, on Refined Brown Aluminum Oxide (also known as Refined Brown Artificial Corundum or Brown Fused Alumina) from the People's Republic of China. This is an AD-only order; no countervailing duty (CVD) case is listed here. Importers of this material should carefully review scope, origin, and exporter/producer identity before entry.

Scope — simplified screening examples, not full legal scope

The official written scope controls. The examples below are screening references only.

Products that may be covered (examples)

•Refined brown aluminum oxide grains from China
•Brown fused alumina abrasive material from China
•Refined brown artificial corundum from China
•Refined brown aluminum oxide sized/graded for abrasive applications
•Brown fused alumina used in grinding wheels or abrasive products
•Refined brown aluminum oxide used in refractory or blasting applications

Products that may require separate review or may fall outside this order

?White aluminum oxide products (may be outside this brown-specific order)
?Unrefined or crude bauxite-derived materials that do not meet the refined-brown definition
?Aluminum oxide from countries other than China (subject to separate origin analysis)
?Finished abrasive tools such as fully manufactured grinding wheels (may depend on scope)
?Other aluminum compounds not meeting the refined brown aluminum oxide description

Scope control: Any HTS codes are screening references only; Commerce's written scope language controls whether a product is covered, and unfinished, unassembled, or downstream forms may still be covered depending on the scope.

Who it affects

This typically matters for importers of abrasive-grade or refractory-grade brown fused alumina/refined brown aluminum oxide sourced from or processed in China, including distributors and manufacturers who buy this material as an input.

What the duty means

If merchandise falls within scope, a cash deposit is generally required at entry; rates vary by exporter/producer and administrative review and can be very high. A 0% cash-deposit rate is NOT an exemption — the order still applies and entries must be declared. Only an AD order is listed here, so no CVD deposit applies under these facts.

Importer checklist — how to assess your risk

☐Gather the commercial invoice description and confirm it matches the product actually shipped.
☐Collect product photos, spec sheets, and grain-size or grade documentation.
☐Document the material composition to confirm whether it is refined brown aluminum oxide/brown fused alumina.
☐Record the intended use (abrasive, refractory, blasting) as context for scope review.
☐Assemble country-of-origin support tracing where the material was produced and processed.
☐Identify the manufacturer and exporter names and confirm the exact producer/exporter combination.
☐Determine the HTS classification for screening purposes only, not as proof of scope.
☐Confirm scope questions with a licensed customs broker or qualified trade counsel; do not rely only on supplier statements.
☐Verify the applicable cash-deposit rate against current Commerce results and CBP AD/CVD messages before filing.

Risks to watch

⚠Circumvention or transshipment findings if goods are routed through third countries to disguise Chinese origin.
⚠Scope inquiries where Commerce clarifies whether a specific form or grade is covered.
⚠Using the wrong exporter/producer combination and applying an incorrect deposit rate.
⚠Misdeclaration or failure to declare, which can trigger penalties and retroactive duty liability.

The same or similar material can be subject to trade-remedy orders from more than one country, so each claimed origin should be reviewed independently and truthfully.

FAQ

Is there antidumping duty on Refined Brown Aluminum Oxide from China?

There is an antidumping duty order, case number A-570-882, on Refined Brown Aluminum Oxide from China. Whether a specific shipment falls within scope depends on Commerce's written scope language, so importers should verify before entry.

Does a 0% deposit rate mean no duty?

No. A 0% cash-deposit rate is not an exemption. The order still applies, the merchandise must be declared as subject, and rates can change through administrative review; final duties are set at liquidation.

Are parts or unassembled Refined Brown Aluminum Oxide covered?

Related or downstream forms may still be covered depending on Commerce's scope. Because this is a raw/processed abrasive material, importers should confirm the specific form and grade against the written scope with a qualified professional.

Possible risk

Risk signal: Higher concern if the goods are refined brown aluminum oxide/brown fused alumina of Chinese origin; separate review is needed for other grades, blends, downstream forms, repackaged goods, and third-country processing.

Bottom line: Refined Brown Aluminum Oxide from China may be covered by AD order A-570-882; confirm scope, origin, exporter/producer identity, and current deposit rates before entry.
