Cast Iron Soil Pipe Fittings — China — C-570-063

“Cast Iron Soil Pipe Fittings” refers to plumbing fittings made from cast iron and used with soil pipe systems, such as fittings that connect, redirect, or close drainage pipe. The exact products covered are defined by the measure’s official scope, which may depend on the product’s physical characteristics, composition, dimensions, and intended use—not only its marketing name or tariff classification.

AD/CVD means antidumping and countervailing duties. Antidumping (AD) duties address imports sold at less than normal value, while countervailing (CVD) duties address benefits that a foreign government provided to producers or exporters. These additional duties generally apply to covered merchandise from specified countries, and they are separate from ordinary customs duty. An importer may be responsible for identifying the measure, declaring the correct tariff classification, paying applicable duties, and maintaining records; the final scope and liability can require customs-broker or trade-lawyer review.

What to check

• Read the official scope language and compare it with the product’s material, design, dimensions, coating, and intended use.
• Confirm the correct Harmonized Tariff Schedule (HTS) classification; do not rely on the product name or a supplier’s classification alone.
• Check whether the country of origin and the actual manufacturer or exporter are covered by the measure, including any company-specific treatment.
• Determine whether the entry requires AD/CVD cash deposits, special entry information, or other procedures in addition to ordinary customs requirements.
• Keep product specifications, bills of materials, invoices, origin records, and supplier statements, and ask a customs broker or trade lawyer to review uncertain scope questions.
