Carbon steel butt-weld pipe fittings from China may be covered by U.S. antidumping duty order A-570-814, an AD (antidumping) order administered by the U.S. Department of Commerce. No countervailing (CVD) order is listed here for this product from China; importers should verify scope and current status against official sources.

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 carbon steel butt-weld pipe fitting elbows
•May include carbon steel butt-weld tees
•May include carbon steel butt-weld reducers
•May include carbon steel butt-weld caps and stub ends
•May include unfinished (rough) carbon steel butt-weld pipe fittings of Chinese origin
•May include fittings finished in a third country from Chinese-origin unfinished fittings (per the anti-circumvention inquiry)
•May include butt-weld fittings sold for welding onto carbon steel pipe

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

?Stainless steel or alloy pipe fittings (commonly outside a carbon steel order, subject to verification)
?Threaded or socket-weld fittings rather than butt-weld type (may be outside scope)
?Forged flanges as opposed to butt-weld fittings (typically separate scope, verify)
?Cast iron or malleable iron fittings (commonly outside a carbon steel butt-weld order)
?Fittings clearly of non-Chinese origin (may be outside this China-specific order)

Scope control: HTS codes are for screening and reference only; Commerce's written scope language controls whether a product is covered, and unfinished, unassembled, or third-country-finished fittings may still be covered depending on the scope and anti-circumvention findings.

Who it affects

This typically matters for importers of carbon steel butt-weld pipe fittings sourced from China, or fittings finished elsewhere from Chinese-origin unfinished blanks, including distributors, pipeline and industrial fabricators, and construction supply importers.

What the duty means

If covered, AD cash deposits are collected at entry; rates vary by exporter/producer and administrative review and can be substantial. A 0% cash-deposit rate is NOT an exemption—the order still applies and entries must be declared. Only an AD order is listed here, so no separate CVD deposit is indicated for this China product.

Importer checklist — how to assess your risk

☐Gather the commercial invoice with a precise product description of the fittings.
☐Collect product photos, spec sheets, and drawings showing the butt-weld type and dimensions.
☐Document the material composition (carbon steel versus stainless/alloy) with mill certificates.
☐Identify the intended use and how the fittings are joined (butt-weld vs. threaded/socket-weld).
☐Obtain country-of-origin support, including where unfinished blanks were made and where finishing occurred.
☐Record the manufacturer and exporter names and confirm the exact producer/exporter combination.
☐Confirm the HTS classification for screening, understanding it is not determinative of scope.
☐Consult a licensed customs broker or trade counsel to confirm scope—do not rely only on supplier statements.
☐Verify the applicable rate against current Commerce results and CBP AD/CVD messages before filing.

Risks to watch

⚠Circumvention or transshipment findings—fittings finished in a third country (e.g., Thailand) from Chinese blanks may be pulled into scope.
⚠Scope inquiries that reinterpret whether specific fittings are covered.
⚠Using the wrong exporter/producer combination and applying an incorrect cash-deposit rate.
⚠Misdeclaration of origin or product type leading to penalties and retroactive duties.

The same product may be subject to separate orders from other countries—a related case exists for Japan—so importers should review each country of origin independently and verify current status without engaging in any evasion.

FAQ

Is there antidumping duty on carbon steel butt-weld pipe fittings from China?

There is an antidumping duty order (A-570-814) covering certain carbon steel butt-weld pipe fittings from China; whether your specific goods fall within scope depends on Commerce's written scope language, so importers should verify before entry.

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 as subject merchandise, and rates can change through administrative reviews.

Are parts or unassembled pipe fittings covered?

Unfinished, rough, or third-country-finished fittings made from Chinese-origin blanks may still be covered depending on Commerce's scope and anti-circumvention findings; importers should verify with a licensed broker or counsel.

Possible risk

Risk signal: Higher concern if the goods are carbon steel butt-weld pipe fittings of Chinese origin, or finished in a third country from Chinese-origin blanks; separate review is needed for material composition, joining type, parts, and third-country processing. This does not state the goods are covered.

Bottom line: Carbon steel butt-weld pipe fittings from China may be covered by antidumping order A-570-814; confirm scope, origin (including any third-country finishing), 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.
