Cast iron soil pipe from China is covered by two U.S. Department of Commerce orders: an antidumping (AD) order, case A-570-079, and a countervailing duty (CVD) order, case C-570-080. Importers of this product should review whether their goods may fall within the scope of both orders 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)

•Hubless cast iron soil pipe (may include pipe made to CISPI 301 or ASTM A888)
•Hub and spigot cast iron soil pipe with one or more hubs
•Finished cast iron soil pipe of any diameter or length
•Unfinished cast iron soil pipe
•Cast iron soil pipe regardless of wall thickness or end finish
•Cast iron soil pipe regardless of surface finish or stenciling
•Nonmalleable cast iron soil pipe connected using cast iron soil pipe fittings

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

?Other types of nonmalleable cast iron pipe not connected like soil pipe (verify scope)
?Cast iron soil pipe fittings themselves (may be a separate matter; verify)
?Malleable iron pipe
?Steel or other non-cast-iron pipe
?Cast iron soil pipe produced in countries other than China

Scope control: The listed HTSUS subheading (7303.00.0030) is a screening reference only; Commerce's written scope language is dispositive, and unfinished cast iron soil pipe may still be covered depending on that scope.

Who it affects

This typically matters for importers, distributors, and plumbing/construction suppliers bringing cast iron soil pipe of Chinese origin into the United States, including both hubless and hub-and-spigot designs.

What the duty means

Cash deposits are collected at entry and can be significant; rates vary by exporter/producer and by administrative review. Because both an AD and a CVD order exist, both types of deposits may apply. A 0% deposit rate is NOT an exemption—the order still applies and the entry must be declared.

Importer checklist — how to assess your risk

☐Gather the commercial invoice with a precise product description of the pipe.
☐Collect product photos, spec sheets, and any CISPI 301 or ASTM A888 references.
☐Confirm the material composition is nonmalleable cast iron versus other metals.
☐Document the intended use and connection method (hubless vs. hub and spigot).
☐Obtain country-of-origin support tracing manufacture to China.
☐Identify the specific manufacturer and exporter names and their combination.
☐Verify the HTS classification with a licensed customs broker for screening.
☐Confirm scope coverage with a licensed customs broker rather than relying only on supplier statements.
☐Verify the applicable cash-deposit rate against current Commerce results and CBP AD/CVD messages before filing.

Risks to watch

⚠Circumvention or transshipment findings if goods are routed through a third country to disguise Chinese origin.
⚠Scope inquiries where Commerce determines whether a specific pipe design is covered.
⚠Using the wrong exporter/producer combination and applying an incorrect deposit rate.
⚠Misdeclaration penalties for failing to declare merchandise subject to the orders.

The same product may face trade-remedy orders from multiple origins, so importers should check the specific facts for each country of origin without engaging in evasion.

FAQ

Is there antidumping duty on cast iron soil pipe from China?

There is an antidumping duty order on cast iron soil pipe from China under case A-570-079, and a separate countervailing duty order under case C-570-080; goods may fall within their scope, 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, the entry must be declared, and rates can change after administrative review.

Are parts or unassembled cast iron soil pipe covered?

Unfinished cast iron soil pipe may still be covered depending on Commerce's written scope; importers should confirm coverage rather than assume exclusion.

Possible risk

Risk signal: Higher concern if the goods are hubless or hub-and-spigot cast iron soil pipe of Chinese origin; separate review is needed for fittings, other cast iron pipe, unfinished items, and any third-country processing.

Bottom line: Cast iron soil pipe from China may be covered by AD case A-570-079 and CVD case C-570-080; 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.
