This explainer covers the U.S. antidumping (AD) duty order on certain polyester staple fiber (PSF) from China under case number A-570-905. It is an AD order only (no CVD order from China is listed here). Importers of PSF of Chinese origin should review whether their goods may fall within the written 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)

•PSF that may be used as stuffing in sleeping bags, mattresses, and comforters
•PSF that may be used as filling in cushions, pillows, and furniture
•PSF that may be used in ski jackets and similar insulated products
•Coated PSF (for example, with a silicone or other finish)
•Uncoated PSF within the covered decitex/denier ranges
•PSF classifiable for reference under HTSUS 5503.20.0045 and 5503.20.0065

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

?PSF of less than 3.3 decitex (less than 3 denier) known as PSF for spinning, generally used in woven and knit textile/apparel applications
?PSF of 10 to 18 denier cut to lengths of 6 to 8 inches generally used to manufacture carpeting
?Low-melt PSF (bi-component fiber with a non-polyester outer sheath melting at a lower temperature than its polyester core)
?Finished textile or apparel products made from fiber rather than the fiber itself

Scope control: HTSUS subheadings such as 5503.20.0045 and 5503.20.0065 are provided for convenience and customs screening only; Commerce's written scope language is dispositive, and coated or uncoated PSF may still be covered depending on that scope.

Who it affects

This typically matters for importers, distributors, and manufacturers bringing in polyester staple fiber of Chinese origin used as stuffing or filling in bedding, cushions, pillows, comforters, sleeping bags, jackets, and furniture.

What the duty means

AD duties are collected as a cash deposit at the time of entry; rates vary by exporter/producer and administrative review and can be high, and a non-listed exporter may fall under the PRC-wide rate. A 0% cash-deposit rate is NOT an exemption — the order still applies and entries must be declared. Only the AD order is listed here, so no separate CVD deposit is indicated for China.

Importer checklist — how to assess your risk

☐Gather the commercial invoice description and confirm it matches the product's technical identity
☐Collect product photos and spec sheets showing decitex/denier, cut length, and coating
☐Verify material composition (polyester content, any bi-component sheath) to compare against excluded categories
☐Document the intended use (stuffing/filling versus spinning or carpeting applications)
☐Obtain country-of-origin support to confirm whether the goods are of Chinese origin
☐Record the manufacturer and exporter names and confirm the specific producer/exporter combination
☐Determine the HTSUS classification for screening, remembering the written scope controls
☐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

⚠Possible circumvention or transshipment findings if PSF is routed or lightly processed through third countries
⚠Scope inquiries where the covered/excluded status of a specific fiber is unclear
⚠Applying the wrong exporter/producer combination and therefore the wrong deposit rate
⚠Misdeclaration exposure, including penalties, if subject goods are entered without proper AD declaration

The same product may be subject to separate proceedings from other origins — related orders on PSF may involve South Korea and Taiwan — so each country of origin should be checked on its own facts.

FAQ

Is there antidumping duty on Polyester Staple Fiber from China?

There is a U.S. antidumping (AD) duty order on certain polyester staple fiber from China under case number A-570-905; whether your specific goods fall within its written scope should be verified with a licensed broker and current Commerce/CBP records.

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 parts or unassembled Polyester Staple Fiber covered?

Fiber-related items may still be covered depending on Commerce's written scope; some fine-denier spinning fiber, carpeting-length fiber, and low-melt bi-component fiber are described as excluded, so verify against the scope language.

Needs review

Risk signal: Higher concern if the goods are polyester staple fiber of Chinese origin used as stuffing or filling; a separate review is needed for spinning-grade fine denier, carpeting-length fiber, low-melt bi-component fiber, coatings, parts, and third-country processing.

Bottom line: Certain polyester staple fiber from China may be covered by AD order A-570-905; confirm scope, origin, exporter/producer identity, and current cash-deposit rates with a licensed broker before entry.
