The U.S. Department of Commerce maintains antidumping (AD) duty order A-570-956 on seamless carbon and alloy steel standard, line, and pressure pipe from China. This is an AD order only; importers of such pipe from China should review whether their goods may fall within its scope 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 seamless carbon steel standard pipe used in general piping applications
•May include seamless line pipe for conveying gas, oil, or water
•May include seamless pressure pipe designed for high-temperature or high-pressure service
•May include seamless alloy steel pipe within the described dimensional and grade ranges
•May include seamless pipe finished or unfinished depending on scope wording
•May include seamless pipe meeting common industry specifications (e.g., ASTM/API grades referenced in scope)
•May include plain-end, beveled-end, or threaded seamless pipe of the covered types

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

?Welded (non-seamless) pipe is commonly outside this seamless-pipe order
?Seamless pipe products such as oil country tubular goods (OCTG) may fall under separate orders rather than this one
?Boiler tubing or mechanical tubing types may be treated differently depending on scope language
?Stainless steel pipe is generally outside a carbon and alloy steel order
?Pipe outside the diameter, wall-thickness, or grade parameters described in the scope may be excluded
?Cast or ductile iron pipe is typically not covered by a steel seamless-pipe order

Scope control: HTS codes are screening references only; Commerce's written scope language controls whether a product is covered, and finished, unfinished, or unassembled pipe may still fall within scope depending on that language.

Who it affects

This typically matters for importers, distributors, and end-users bringing in seamless carbon or alloy steel standard, line, or pressure pipe from China, especially those relying on Chinese mills or trading intermediaries.

What the duty means

AD duties are collected as cash deposits at entry; rates vary by exporter/producer and administrative review and can be high. A 0% cash-deposit rate is NOT an exemption — the order still applies and the entry must be declared as subject merchandise.

Importer checklist — how to assess your risk

☐Gather the commercial invoice description and confirm it matches the seamless pipe type stated on the goods
☐Collect product photos, mill test reports, and spec sheets showing grade, dimensions, and manufacturing method
☐Verify the material composition (carbon vs. alloy steel) and whether the pipe is truly seamless
☐Document the intended use (standard, line, or pressure service) to compare against scope wording
☐Assemble country-of-origin support tracing the pipe to its actual manufacturing location
☐Identify the manufacturer and exporter names and confirm the exact producer/exporter combination
☐Determine the proper HTS classification for screening, understanding it does not control scope
☐Confirm scope coverage 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 when Chinese pipe is routed through third countries
⚠Scope inquiries that may clarify borderline or unfinished pipe products
⚠Applying the wrong exporter/producer combination and thus an incorrect deposit rate
⚠Misdeclaration or non-declaration exposing the importer to penalties and retroactive duties

The same type of seamless pipe may be subject to trade-remedy orders from other countries as well, so importers should review each country of origin independently.

FAQ

Is there antidumping duty on seamless pipe from China?

Commerce maintains AD order A-570-956 on seamless carbon and alloy steel standard, line, and pressure pipe 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 AD order still applies, the merchandise must be declared as subject, and rates can change through administrative reviews.

Are parts or unassembled seamless pipe covered?

Unfinished or further-processable pipe may still be covered depending on Commerce's scope language; importers should confirm coverage with a licensed broker rather than assume exclusion.

Possible risk

Risk signal: Higher concern if the goods are seamless carbon or alloy steel standard, line, or pressure pipe of Chinese origin; a separate review is needed for welded pipe, OCTG, stainless products, unfinished pipe, and any third-country processing.

Bottom line: Seamless carbon and alloy steel standard, line, and pressure pipe from China may be covered by AD order A-570-956; 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.
