The United States maintains an antidumping (AD) duty order on certain activated carbon from China, identified by case number A-570-904. This is an AD order only; no separate countervailing duty case number is provided here. Importers of activated carbon of Chinese origin may want to review whether their products fall within this order's scope.

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)

•May include steam-activated carbon in powdered form
•May include steam-activated carbon in granular form
•May include steam-activated carbon in pelletized form
•May include coal-based activated carbon used for water or air purification
•May include activated carbon regardless of packaging or container size
•May include blends where activated carbon is combined with inert or other materials, depending on scope

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

?Chemically activated carbon (as opposed to steam-activated) may fall outside, depending on scope
?Certain specialty carbons produced by processes other than steam activation may be outside
?Products that are not activated carbon (e.g., raw carbon feedstock that has not been activated) may be outside
?Carbon-based products of non-Chinese origin are addressed under other or no orders
?Finished appliances or filters that merely contain activated carbon may be treated differently — verify

Scope control: Any HTS codes are screening references only; Commerce's written scope language controls whether a product is covered, and blends, unfinished, or partially processed activated carbon may still be within scope depending on the scope wording.

Who it affects

This typically matters for importers, distributors, and manufacturers sourcing powdered, granular, or pelletized steam-activated carbon from China for water treatment, air/gas purification, food and beverage processing, or industrial filtration.

What the duty means

Antidumping cash deposits are collected at entry; rates vary by exporter/producer and by administrative review and can be substantial. A 0% cash-deposit rate is NOT an exemption — the order still applies, entries must be declared, and rates can change after review.

Importer checklist — how to assess your risk

☐Gather the commercial invoice with a detailed product description of the activated carbon.
☐Collect product photos, spec sheets, and technical data showing form (powder, granular, pelletized).
☐Document the material composition and the activation method (e.g., steam-activated).
☐Record the intended use (water treatment, air purification, industrial, etc.).
☐Obtain country-of-origin support and trace the manufacturing/activation location.
☐Identify both the manufacturer and the exporter, and confirm the specific producer/exporter combination.
☐Confirm the HTS classification with a licensed customs broker for screening purposes.
☐Verify scope questions and the current cash-deposit rate against current Commerce results and CBP AD/CVD messages before filing.
☐Do not rely only on supplier statements about coverage or origin — obtain independent verification.

Risks to watch

⚠Circumvention or transshipment findings where Chinese-origin carbon is routed through third countries.
⚠Scope inquiries that may clarify whether a specific product or blend is within the order.
⚠Using the wrong exporter/producer combination, which can lead to an incorrect (often higher) deposit rate.
⚠Misdeclaration of origin, composition, or scope, which can trigger penalties and retroactive duties.

The same product may be subject to trade remedies from more than one country over time, so verify the specific origin of each shipment through legitimate documentation rather than assuming any origin avoids review.

FAQ

Is there antidumping duty on activated carbon from China?

The United States maintains an antidumping (AD) duty order on certain activated carbon from China under case number A-570-904. Whether your specific product is covered depends on Commerce's written scope, 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, entries must be declared, and the rate may change after an administrative review, potentially resulting in duties owed.

Are parts or unassembled activated carbon covered?

Activated carbon that is blended, packaged differently, or otherwise processed may still fall within scope depending on Commerce's written scope language. Importers should confirm scope with a licensed broker and Commerce results before filing.

Needs review

Risk signal: Higher concern if the goods are steam-activated carbon of Chinese origin in powdered, granular, or pelletized form; separate review needed for chemically activated carbon, blends, repackaged goods, and third-country processing.

Bottom line: Activated carbon from China may be covered by AD case A-570-904; confirm scope, origin, exporter/producer identity, and current deposit rates against Commerce and CBP guidance 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.
