U.S. Antidumping and Countervailing Duties on Oil Country Tubular Goods (OCTG) from China (A-570-943 / C-570-944)

This is an educational summary — NOT a scope determination or filing advice. It does not decide whether your specific goods are covered. Always verify against the latest U.S. Commerce and CBP instructions.

Oil Country Tubular Goods (OCTG) from China are subject to both a U.S. antidumping order (A-570-943) and a countervailing duty order (C-570-944).

Oil Country Tubular Goods (OCTG) from China are covered by two U.S. Department of Commerce trade-remedy orders: antidumping case A-570-943 and countervailing duty case C-570-944. This means both AD and CVD may apply to qualifying imports, and importers should carefully verify scope, origin, and current cash-deposit rates 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)

•OCTG may include seamless tubular products used in oil and gas drilling or extraction
•OCTG may include welded tubular products regardless of end finish
•May include casing and tubing whether or not conforming to API specifications
•May include products conforming to non-API specifications
•May include finished or unfinished OCTG
•May include OCTG whether or not thread protectors are attached
•May include OCTG coupling stock
•May include seamless OCTG completed in Thailand from Chinese-origin steel billets (per the affirmative circumvention determination)

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

?Line pipe used for transporting oil or gas (commonly outside OCTG orders, but verify)
?Standard pipe or structural pipe not intended for oilfield drilling/extraction use
?Mechanical or pressure tubing for non-oilfield applications
?Products made in Thailand certified as not made with Chinese-origin steel billets (subject to certification requirements)
?Finished couplings that are not coupling stock (verify against written scope)

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

Who it affects

This typically matters for importers of seamless or welded oilfield casing, tubing, drill pipe, and coupling stock of Chinese origin — and potentially seamless OCTG completed in Thailand using Chinese-origin billets, given the circumvention finding.

What the duty means

Cash deposits are collected at entry; rates vary by exporter/producer and administrative review and can be high. Because both an AD (A-570-943) and a CVD (C-570-944) order exist, both types of 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 a full product description of the tubular goods
☐Collect product photos, mill certificates, and spec sheets (API or non-API specification, seamless vs. welded)
☐Document material composition and the origin of the steel billets or input used
☐Identify the intended end use (oilfield drilling/extraction vs. other applications)
☐Assemble country-of-origin support, including production and processing records
☐Record the manufacturer and exporter names and confirm the exact producer/exporter combination
☐Confirm the HTS classification with a licensed customs broker for screening only
☐Verify current cash-deposit rates against the latest Commerce results and CBP AD/CVD messages before filing
☐Do not rely only on supplier statements; obtain and retain any required certifications, especially for Thailand-completed seamless OCTG

Risks to watch

⚠Circumvention/transshipment findings — Commerce made an affirmative country-wide determination that seamless OCTG completed in Thailand from Chinese-origin billets circumvents the orders
⚠Scope inquiries that could reclassify borderline products as covered
⚠Using the wrong exporter/producer combination, resulting in an incorrect deposit rate
⚠Misdeclaration or missing certifications leading to penalties, retroactive duties, and enforcement action

The same product may be subject to separate orders in other countries — related OCTG cases exist for Argentina, South Korea, Mexico, Russia, and Ukraine — so importers should review each country of origin independently.

FAQ

Is there antidumping duty on Oil Country Tubular Goods from China?

There is an antidumping order (A-570-943) and a separate countervailing duty order (C-570-944) on OCTG from China. Qualifying imports may be covered by both, but 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 AD and/or CVD order still applies, entries must be declared, and rates can change through administrative review and later liquidation.

Are parts or unassembled OCTG covered?

OCTG may be covered whether finished or unfinished, and coupling stock is also within scope per the order language, so such items may still be covered depending on Commerce's written scope. Verify each product before filing.

Possible risk

Risk signal: Higher concern if the goods are seamless or welded OCTG or coupling stock of Chinese origin, or seamless OCTG completed in Thailand from Chinese-origin billets; separate review is needed for products from other countries, non-oilfield tubulars, and certified non-Chinese-input goods.

Bottom line: OCTG from China may be covered by A-570-943 (AD) and C-570-944 (CVD), and Thailand-completed seamless OCTG may be affected via circumvention; confirm scope, origin, exporter/producer identity, and current deposit rates before entry.
