Large diameter welded structural pipe from China may be covered by U.S. countervailing duty order C-570-078, a CVD order administered by the U.S. Department of Commerce. This is a CVD (subsidy-offsetting) order; no antidumping (AD) case is listed here for this product from China. Importers should verify whether their specific goods fall within the written scope 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)
  • May include welded carbon or alloy steel structural pipe more than 406.4 mm (16 inches) in nominal outside diameter
  • May include structural pipe used for piling and other structural purposes
  • May include pipe produced to ASTM A500, A252, or A53 or comparable foreign/proprietary specifications
  • May include non-graded structural pipe meeting the physical description
  • May include dual- or multiple-certified/stenciled pipe carrying an ASTM (or comparable) welded structural pipe certification
  • May include in-scope pipe further processed in a third country (e.g., coating, painting, notching, beveling, cutting) that would not otherwise remove it from scope
Products that may require separate review or may fall outside this order
  • ?May exclude stainless steel pipe
  • ?May exclude pipe 406.4 mm (16 inches) or less in nominal outside diameter
  • ?May exclude large diameter welded pipe produced only to AWWA specifications for water and sewage pipe
  • ?May exclude line pipe suitable for transporting oil, gas, slurry, steam, or other fluids and normally produced to API specification 5L or equivalent
Scope control: The listed HTSUS subheadings are provided for convenience and screening only; Commerce's written scope language is dispositive, and pipe further processed in a third country may still be covered depending on scope.

Who it affects

This typically matters for importers of Chinese-origin welded steel structural pipe over 16 inches in diameter, including product intended for piling or other structural applications, and for those importing such pipe that has undergone third-country finishing.

What the duty means

CVD cash deposits are collected at entry to offset alleged subsidies; rates vary by exporter/producer and administrative review and can be high. A 0% cash-deposit rate is NOT an exemption — the order still applies and entries must be declared. Only a CVD order (C-570-078) is listed here for this product from China.

Importer checklist — how to assess your risk

  • Gather the commercial invoice description and confirm the nominal outside diameter against the 16-inch (406.4 mm) threshold
  • Collect product photos, spec sheets, and mill test certificates showing grade, stencil, and standards
  • Document the material composition (carbon, alloy, or stainless steel)
  • Identify the intended use (structural/piling vs. line pipe vs. water/sewage)
  • Assemble country-of-origin support, including records of any third-country processing
  • Record the manufacturer and exporter names and confirm the exact producer/exporter combination
  • Determine the HTSUS classification for screening purposes only
  • Confirm scope applicability with a licensed customs broker or trade counsel
  • 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 for pipe routed or processed through third countries
  • Scope inquiries where product characteristics (diameter, grade, specification) are borderline
  • Applying the wrong exporter/producer combination and thus an incorrect cash-deposit rate
  • Misdeclaration penalties and retroactive duties for goods entered without proper AD/CVD declaration
The same product is subject to separate U.S. proceedings involving Canada, Greece, India, South Korea, and Turkey (verify each real case), so importers should review every country of origin independently rather than assume any single sourcing solution.

FAQ

Is there antidumping duty on Large Diameter Welded Pipe from China?
The case listed here for this product from China is a countervailing duty (CVD) order, C-570-078. Only that CVD case is provided; importers should verify with Commerce whether any separate antidumping order also applies before assuming coverage.
Does a 0% deposit rate mean no duty?
No. A 0% cash-deposit rate is not an exemption. The order under C-570-078 still applies, entries must be declared, and rates can change through administrative reviews.
Are parts or unassembled Large Diameter Welded Pipe covered?
Coverage depends on Commerce's written scope. The scope notably includes in-scope pipe further processed in a third country (e.g., coating, cutting, beveling); importers should confirm specific situations with a licensed broker or counsel.
Needs review
Risk signal: Higher concern if the goods are welded structural steel pipe over 16 inches in diameter of Chinese origin; a separate review is needed for line pipe, water/sewage (AWWA) pipe, stainless pipe, smaller diameters, and third-country processing.
Bottom line: Large diameter welded pipe from China may be covered by CVD order C-570-078; 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.
