Circular welded carbon quality steel pipe from China may fall within two U.S. Department of Commerce orders: antidumping case A-570-910 and countervailing duty case C-570-911. Importers of this product should carefully review whether their goods may be covered, since both AD and CVD cash deposits may apply.

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 circular welded carbon quality steel pipe with an outside diameter of 0.372 inches or more but not more than 16 inches
•May include standard welded steel pipe of circular cross-section within that diameter range
•May include welded carbon quality steel tube of circular cross-section within the covered size range
•May include such pipe whether plain end, threaded, or coupled, depending on written scope
•May include pipe completed in Vietnam using China-origin hot-rolled steel per a circumvention finding
•May include galvanized or otherwise coated welded carbon quality pipe within scope parameters

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

?Pipe with an outside diameter greater than 16 inches may fall outside this order
?Pipe with an outside diameter under 0.372 inches may fall outside this order
?Stainless steel or alloy pipe not meeting the carbon quality definition may be outside scope
?Seamless (non-welded) pipe is typically a different product line and may fall outside this order
?Line pipe, oil country tubular goods, or other specialty pipe may be covered by separate orders or excluded — verify
?Non-circular cross-section pipe or tube may fall outside this order

Scope control: HTS codes serve only as screening references; Commerce's written scope language controls whether a product is covered, and parts, unfinished, or further-processed items (including pipe finished in a third country using China-origin steel) may still be covered depending on scope.

Who it affects

This typically matters for importers of welded carbon steel pipe and tube of circular cross-section in the 0.372-to-16-inch outside-diameter range sourced from China, and potentially for pipe finished in Vietnam using China-origin hot-rolled steel.

What the duty means

AD and CVD cash deposits are collected at entry and rates vary by exporter/producer and administrative review; they can be high, and because both an AD and a CVD order exist, both 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 including diameter and wall specifications
☐Collect product photos and spec/mill test sheets showing dimensions and steel type
☐Confirm material composition to verify carbon quality steel versus alloy or stainless
☐Document the intended use and product form (plain end, threaded, coated, etc.)
☐Obtain country-of-origin support, including where any China-origin steel was further processed
☐Identify the manufacturer and exporter names and confirm the exact producer/exporter combination
☐Determine the likely HTS classification for screening purposes only
☐Consult a licensed customs broker or trade counsel to confirm scope; 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 — Commerce has found pipe completed in Vietnam using China-origin hot-rolled steel may be within scope
⚠Scope inquiries that could bring borderline products within the order
⚠Using the wrong exporter/producer combination, which can result in an incorrect (often higher) deposit rate
⚠Misdeclaration or failure to declare, which can expose importers to penalties and retroactive duties

The same product may be subject to AD/CVD orders from multiple countries, so importers should independently verify the treatment of each country of origin without engaging in any evasion.

FAQ

Is there antidumping duty on circular welded carbon quality steel pipe from China?

There is an antidumping order under case A-570-910 and a countervailing duty order under case C-570-911 on this product from China; your specific goods may fall within scope, so confirm with Commerce's written scope and CBP before filing.

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 can change through administrative review or later assessment.

Are parts or unassembled circular welded steel pipe covered?

Parts, unfinished, or further-processed pipe may still be covered depending on Commerce's written scope; notably, pipe completed in Vietnam using China-origin hot-rolled steel has been found to be within scope, so verify carefully.

Possible risk

Risk signal: Higher concern if the goods are circular welded carbon quality steel pipe of China origin within the covered diameter range; separate review is needed for oversized or undersized pipe, alloy/stainless variations, parts, and third-country processing such as finishing in Vietnam with China-origin steel.

Bottom line: Circular welded carbon quality steel pipe from China may be covered by AD case A-570-910 and CVD case C-570-911; 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.
