Circular welded carbon quality steel line pipe imported from China may fall within the scope of two U.S. Department of Commerce trade-remedy orders: antidumping case A-570-935 and countervailing duty case C-570-936. Because both an AD and a CVD order may apply, importers should carefully review product scope, origin, and their exporter/producer combination 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)

•Circular welded carbon quality steel line pipe used to transport oil, gas, or other fluids may be covered
•Welded line pipe produced to API or comparable industry specifications may be covered
•Line pipe in a range of nominal diameters that meets carbon quality steel definitions may be covered
•Line pipe supplied plain-end, beveled, or threaded may be covered depending on scope
•Coated or uncoated welded carbon quality line pipe may be covered
•Line pipe imported cut to length or in standard lengths may be covered

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

?Seamless (non-welded) steel pipe is commonly addressed under different products or orders
?Standard pipe and structural pipe not meeting the line pipe definition may be outside this order
?Stainless steel or high-alloy pipe generally falls outside a carbon quality steel order
?Oil country tubular goods (OCTG) such as casing and tubing are typically covered by separate orders
?Pressure pipe or mechanical tubing not meeting the line pipe scope may be outside this order

Scope control: HTS codes are screening references only; Commerce's written scope language ultimately controls whether a product is covered, and unfinished, unassembled, or further-processed items may still fall within scope.

Who it affects

This typically matters for importers, distributors, and pipeline or construction buyers sourcing welded carbon quality steel line pipe of Chinese origin, or products that may have been produced or finished in China.

What the duty means

If goods fall within scope, cash deposits are collected at entry; rates vary by exporter/producer and administrative review and can be substantial. Because both AD (A-570-935) and CVD (C-570-936) orders may apply, deposits under both could be owed. A 0% 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 a detailed product description including pipe type and specification
☐Collect product photos, mill test reports, and spec sheets showing dimensions and standards
☐Confirm the material composition to determine whether it is carbon quality steel
☐Document the intended use (line pipe versus standard, structural, or OCTG use)
☐Obtain country-of-origin support tracing where the pipe was manufactured and finished
☐Identify the specific manufacturer and exporter names and the exact producer/exporter combination
☐Determine the correct HTS classification for screening purposes only
☐Confirm potential scope coverage with a licensed customs broker or trade attorney, and do not rely only on supplier statements
☐Verify the current cash-deposit rate against the latest Commerce results and CBP AD/CVD messages before filing

Risks to watch

⚠Circumvention or transshipment findings when Chinese-origin pipe is routed through third countries
⚠Scope inquiries where a product's coverage is uncertain and requires a Commerce ruling
⚠Applying the wrong exporter/producer combination, which can change the applicable deposit rate
⚠Misdeclaration of origin, scope, or value, which can trigger penalties and retroactive duty liability

The same or similar line pipe products may be subject to separate orders from other countries, so each country of origin should be reviewed on its own facts rather than assumed to be equivalent.

FAQ

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

There is a U.S. antidumping order under case A-570-935 and a countervailing duty order under case C-570-936 covering this product from China; whether your specific goods fall within scope depends on Commerce's written scope language and should be verified.

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, potentially affecting final liability.

Are parts or unassembled line pipe covered?

Unfinished, further-processed, or partially completed line pipe may still be covered depending on Commerce's scope language; importers should verify rather than assume such items are outside the order.

Possible risk

Risk signal: Higher concern if the goods are welded carbon quality steel line pipe of Chinese origin; separate review is needed for coatings, further processing, parts, unfinished forms, and any third-country processing.

Bottom line: Circular welded carbon quality steel line pipe from China may be covered by A-570-935 (AD) and C-570-936 (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.
