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.
- •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
- ?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
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
