Effective/entry-specific deposit and liquidation treatment depends on Commerce and CBP instructions, not only the publication date.

The U.S. Department of Commerce maintains both an antidumping duty order (A-570-954) and a countervailing duty order (C-570-955) on certain magnesia carbon bricks from China. Importers of these refractory bricks should review whether their goods may fall within the written scope of these orders.

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)

•Chemically-bonded (resin or pitch) magnesia carbon bricks that may include an MgO component of at least 70 percent by weight
•Magnesia carbon bricks that may include carbon levels ranging from trace amounts up to about 30 percent by weight
•Bricks that may be enhanced with coating, grinding, or tar impregnation
•Bricks that may be coked or subjected to high-temperature heat treatment
•Bricks with anti-slip treatments or metal casing that may fall within scope
•Bricks containing antioxidants (metals, metal alloys, or metal carbides) that may be present in varying amounts
•Magnesia carbon bricks regardless of the raw-material source of the MgO

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

?Bricks with an MgO content below the scope threshold may be outside the order
?Bricks with carbon content above the scope range may fall outside coverage
?Non-magnesia refractory bricks (for example, purely alumina or silica bricks) are typically not this product
?Refractory castables, mortars, or monolithic (unshaped) refractory products may be outside the scope
?Magnesia bricks that are not chemically (resin/pitch) bonded may fall outside coverage

Scope control: HTS subheadings are provided only as screening references; Commerce's written scope description is dispositive as to whether a product is covered, and certain treated or enhanced bricks may still fall within scope depending on that language.

Who it affects

This typically matters for importers, distributors, and steel/foundry/refractory end users sourcing magnesia carbon refractory bricks of Chinese origin for furnace or ladle linings.

What the duty means

If covered, goods generally require AD and/or CVD cash deposits at the time of entry; rates vary by exporter/producer and administrative review and can be substantial. A 0% cash-deposit rate is NOT an exemption — the order still applies and entries must be declared. Because both AD and CVD orders exist, both types of deposits may apply.

Importer checklist — how to assess your risk

☐Gather the commercial invoice description and match it against the written scope language
☐Collect product photos, spec sheets, and technical data sheets showing MgO percentage and carbon content
☐Verify material composition, including antioxidant type and any coatings or treatments
☐Document the intended use (for example, furnace or ladle lining)
☐Confirm country-of-origin support and manufacturing location records
☐Identify the specific manufacturer and exporter names and confirm the producer/exporter combination
☐Determine the likely HTS classification for screening, understanding the written scope controls
☐Consult a licensed customs broker or trade counsel for a scope assessment; 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 when Chinese-origin bricks are routed through third countries
⚠Scope inquiries that may clarify whether enhanced or treated bricks are covered
⚠Applying the wrong exporter/producer combination, leading to an incorrect deposit rate
⚠Misdeclaration or failure to declare, which may result in penalties and retroactive duty liability

The same product may be subject to trade remedies from more than one origin — magnesia carbon bricks from Mexico were also investigated — so each country of origin should be reviewed on its own facts without any effort to evade duties.

FAQ

Is there antidumping duty on magnesia carbon bricks from China?

There is an antidumping duty order on certain magnesia carbon bricks from China under case A-570-954, and a separate countervailing duty order under C-570-955; whether your specific bricks are covered depends on Commerce's written scope.

Does a 0% deposit rate mean no duty?

No. A 0% cash-deposit rate is not an exemption. The order still applies, entries must be declared, and rates can change through administrative reviews.

Are treated or enhanced magnesia carbon bricks covered?

They may still be covered depending on Commerce's scope, which describes bricks regardless of coating, grinding, tar impregnation, coking, heat treatment, anti-slip treatment, metal casing, or antioxidant content; verify with a licensed broker.

Possible risk

Risk signal: Higher concern if the goods are chemically-bonded magnesia carbon bricks of Chinese origin meeting the scope's MgO and carbon thresholds; separate review is needed for enhanced, coated, or treated bricks, blends, parts, and third-country processing. This does not state the goods are covered.

Bottom line: Certain magnesia carbon bricks from China may be covered by AD case A-570-954 and CVD case C-570-955; confirm scope, origin, exporter/producer identity, and current deposit rates before entry.

Not a scope determination or filing advice — confirm coverage and current deposit rates with a licensed customs broker and the latest Commerce/CBP instructions before entry.
