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 order (A-570-038) and a countervailing duty order (C-570-039) on amorphous silica fabric from China. Importers of high-silica woven fabric or related textile products may need to review whether their goods fall within the scope of these two orders 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)

•May include woven fabric made from high-purity amorphous silica yarn
•May include heat-treated or leached silica fabrics with high silica content
•May include silica cloth used for thermal insulation or welding protection
•May include silica fabric in rolls or cut-to-size pieces regardless of width
•May include silica fabric that is coated, treated, or finished if the base fabric meets the scope
•May include silica fabric imported for high-temperature or fire-protection applications

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

?Fiberglass fabrics with lower silica content may fall outside the scope (verify)
?Ceramic fiber or mineral-wool based fabrics may be outside the scope
?Non-woven silica products or loose silica fiber may be outside the described fabric scope
?Fabrics not meeting the specified amorphous silica content threshold may be excluded
?Finished articles that are not the fabric itself may require separate scope review

Scope control: HTS codes are screening references only; Commerce's written scope language controls whether a product is covered, and coated, treated, or further-processed fabric may still be within scope depending on the exact wording.

Who it affects

This typically matters for importers of woven high-silica or amorphous silica fabrics from China used in thermal insulation, welding blankets, fire protection, or high-temperature industrial applications.

What the duty means

Cash deposits are collected at entry for both the AD and CVD orders; rates vary by exporter/producer and administrative review and can be substantial. Because both orders exist, both AD and CVD deposits may apply. A 0% cash-deposit rate is NOT an exemption — the order still applies and entries must be declared.

Importer checklist — how to assess your risk

☐Gather the commercial invoice with the full product description and specifications
☐Collect product photos and spec sheets showing weave, weight, and construction
☐Document the material composition, especially the amorphous silica content percentage
☐Describe the intended end use, such as thermal insulation or welding protection
☐Obtain country-of-origin support tracing the fabric back to its manufacturer
☐Identify the manufacturer and exporter names and the specific producer/exporter combination
☐Determine the likely HTS classification for screening purposes only
☐Confirm scope questions with a licensed customs broker or trade counsel rather than relying 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 that may reveal a product falls within the written scope despite initial assumptions
⚠Using the wrong exporter/producer combination and applying an incorrect deposit rate
⚠Misdeclaration or misclassification exposing the importer to penalties and retroactive duties

The same or similar product may be subject to trade remedy orders in other countries, so importers should review each country of origin independently rather than assume any single source is unaffected.

FAQ

Is there antidumping duty on amorphous silica fabric from China?

There is an antidumping duty order (A-570-038) and also a countervailing duty order (C-570-039) covering amorphous silica fabric from China; whether your specific goods are covered depends on Commerce's written scope, which importers should verify.

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 review, so importers should confirm current results before filing.

Are parts or unassembled amorphous silica fabric covered?

Fabric that is coated, treated, cut-to-size, or otherwise further processed may still fall within scope depending on Commerce's written scope language; importers should verify rather than assume any form is excluded.

Possible risk

Risk signal: Higher concern if the goods are woven high-silica or amorphous silica fabric of Chinese origin; a separate review is needed for lower-silica fiberglass, coated or finished variants, non-woven forms, parts, and any third-country processing.

Bottom line: Amorphous silica fabric from China may be covered by A-570-038 (AD) and C-570-039 (CVD); 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.
