U.S. Antidumping and Countervailing Duties on Cast Iron Soil Pipe Fittings from China (A-570-062, C-570-063)

Cast iron soil pipe fittings from China may fall within two U.S. Department of Commerce orders: an antidumping (AD) order under case A-570-062 and a countervailing duty (CVD) order under case C-570-063. Because both an AD and a CVD order exist, both types of cash deposits may apply to covered entries.
Scope — simplified screening examples, not full legal scope
The official written scope controls. The examples below are screening references only.
- •Nonmalleable cast iron soil pipe fittings, finished or unfinished, of any size
- •Hubless (no-hub) fittings, often made to CISPI 301 or ASTM A888 specifications
- •Hub and spigot fittings that connect to cast iron soil pipe
- •Bends and elbows used in soil pipe drainage systems
- •Tees and wyes for cast iron soil pipe assemblies
- •Traps used with cast iron soil pipe
- •Drains (other than drain bodies) and other common or special fittings
- •Fittings with or without side inlets
- ?Drain bodies, which Commerce/ITC treated as a separate product and excluded from these orders
- ?Malleable cast iron fittings (the scope covers nonmalleable castings)
- ?Fittings that connect to pipe by a different method than cast iron soil pipe
- ?Cast iron fittings intended for uses other than soil pipe drainage systems
- ?Finished drain fixtures assembled from drain bodies with strainers, grates, or bolts
Who it affects
This typically matters for importers, distributors, and plumbing/construction suppliers bringing in cast iron soil pipe fittings of Chinese origin, including hubless and hub-and-spigot fittings such as bends, tees, wyes, and traps.
What the duty means
Covered goods generally require cash deposits at entry. Because both an AD order (A-570-062) and a CVD order (C-570-063) exist, both AD and CVD deposits may apply. Rates vary by exporter/producer and administrative review and can be high; importantly, a 0% deposit rate is NOT an exemption—the order still applies and entries must still be declared.
Importer checklist — how to assess your risk
- ☐Gather the commercial invoice description and confirm it matches the actual fitting type.
- ☐Collect product photos and spec sheets, noting whether fittings are hubless or hub-and-spigot.
- ☐Verify material composition to confirm nonmalleable cast iron.
- ☐Document the intended use to distinguish fittings from excluded drain bodies.
- ☐Obtain country-of-origin support and manufacturing records for the goods.
- ☐Identify the specific manufacturer and exporter names, and confirm the exact producer/exporter combination.
- ☐Determine the correct HTS classification for screening purposes.
- ☐Confirm scope questions with a licensed customs broker or trade counsel, and do not rely 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 third countries to disguise Chinese origin.
- ⚠Scope inquiries where a product's coverage under A-570-062 or C-570-063 is uncertain.
- ⚠Using the wrong exporter/producer combination and applying an incorrect deposit rate.
- ⚠Misdeclaration penalties, retroactive duties, and interest for failing to declare covered merchandise.
