Circular welded austenitic stainless pressure pipe from China may fall within two U.S. Department of Commerce orders: an antidumping order (A-570-930) and a countervailing duty order (C-570-931). Because both an AD and a CVD order exist, importers of this pipe from China should carefully review scope, origin, and current cash-deposit requirements 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 austenitic stainless pressure pipe 14 inches or less in outside diameter
•Pipe produced to ASTM A-312 specifications (or comparable domestic/foreign specifications)
•Pipe produced to ASTM A-778 specifications (or comparable domestic/foreign specifications)
•ASTM A-358 products, but only when made to meet ASTM A-312 or A-778 (or comparable) specifications
•Stainless pressure pipe of Chinese origin entering under the referenced HTSUS 7306.40 subheadings
•Comparable circular welded austenitic stainless pressure pipe under foreign specifications equivalent to A-312 or A-778

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

?Welded stainless mechanical tubing meeting ASTM A-554 (or comparable specifications)
?Boiler, heat exchanger, superheater, refining furnace, feedwater heater, and condenser tubing meeting ASTM A-249 or A-688 (or comparable)
?Specialized tubing meeting ASTM A-269 or A-270 (or comparable specifications)
?Pipe greater than 14 inches in outside diameter
?ASTM A-358 products not produced to meet A-312 or A-778 specifications

Scope control: The listed HTSUS 7306.40 subheadings are provided for screening and customs convenience only; Commerce's written scope language is dispositive as to whether a product is covered, and related or unfinished forms may still fall within scope depending on that language.

Who it affects

This typically matters for importers, distributors, and fabricators sourcing small-diameter welded stainless pressure pipe (14 inches or less in outside diameter) of Chinese origin, particularly product produced to ASTM A-312 or A-778 or comparable specifications.

What the duty means

Covered goods generally require AD and/or CVD cash deposits at the time of entry; rates vary by exporter/producer and by administrative review and can be significant. Because both an AD (A-570-930) and a CVD (C-570-931) 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 product description and match it against Commerce's written scope language.
☐Collect product photos, spec sheets, and mill certificates showing the applicable ASTM (or comparable) specification.
☐Confirm the outside diameter to determine whether it exceeds the 14-inch threshold.
☐Verify the material composition to confirm austenitic stainless steel content.
☐Document the intended use and any specification the pipe was manufactured to meet.
☐Assemble country-of-origin support, including manufacturing and processing records.
☐Identify the exact manufacturer, producer, and exporter names and confirm the specific producer/exporter combination.
☐Review the HTSUS classification against the referenced 7306.40 subheadings as a screening step only.
☐Confirm scope with a licensed customs broker or trade counsel, and verify current rates against the latest Commerce results and CBP AD/CVD messages before filing — do not rely only on supplier statements.

Risks to watch

⚠Third-country transshipment or minor processing may trigger circumvention or evasion findings.
⚠Products near scope boundaries (specification, diameter) may prompt a Commerce scope inquiry.
⚠Declaring the wrong exporter/producer combination can result in an incorrect cash-deposit rate.
⚠Misdeclaration of origin, scope, or classification can lead to penalties and retroactive duty liability.

The same product may be subject to trade-remedy orders in more than one country, so importers should independently review the scope and duty status for each country of origin they source from.

FAQ

Is there antidumping duty on circular welded austenitic stainless pressure pipe from China?

There is an antidumping order (A-570-930) and a separate countervailing duty order (C-570-931) on this product from China. Whether your specific goods are covered depends on Commerce's written scope; importers should verify 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 rates can change through administrative reviews, so verify current results before entry.

Are parts or unassembled pipe covered?

Related, unfinished, or component forms may still fall within scope depending on Commerce's written scope language; importers should confirm with a licensed broker or trade counsel rather than assuming exclusion.

Possible risk

Risk signal: Higher concern if the goods are small-diameter (14 inches or less) circular welded austenitic stainless pressure pipe of Chinese origin made to ASTM A-312 or A-778 or comparable specifications; separate review is needed for other tubing types, larger diameters, third-country processing, and unfinished forms. This does not state that your goods are covered.

Bottom line: Circular welded austenitic stainless pressure pipe from China may be covered by A-570-930 (AD) and C-570-931 (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.
