Non-Refillable Steel Cylinders — China — C-570-127

An AD/CVD measure is a trade remedy covering possible unfair pricing or government assistance. “AD” means antidumping: foreign merchandise is allegedly sold in the United States at less than fair value. “CVD” means countervailing duty: imported merchandise allegedly benefits from subsidies provided by a foreign government. A measure titled “Non-Refillable Steel Cylinders” generally concerns certain single-use steel cylinders, but the legal scope—not the title alone—determines which products are covered.

It typically affects foreign producers and exporters, U.S. importers, and sometimes related parties involved in the sale or entry. An importer may need to provide accurate product, producer, exporter, origin, and entry information and may be responsible for additional duties if the merchandise is within scope. These duties are separate from ordinary customs duty and may be collected through cash-deposit requirements and later assessment, so an importer should verify the measure with official sources or a qualified customs broker before entry.

What to check

• Read the official scope language and compare the cylinder’s materials, design, capacity, refillability, fittings, and intended use; do not rely on the product title alone.
• Confirm the tariff classification (HTSUS subheading), country of origin, manufacturer, exporter, and supplier against the measure’s coverage; classification by itself does not decide scope.
• Check whether the specific producer or exporter has its own applicable instructions, cash-deposit requirement, or exclusion, and verify the current instructions with CBP and Commerce sources.
• Ask a customs broker or trade-remedy specialist to review ambiguous products and, when appropriate, seek a formal scope ruling from the relevant authority.
• Keep purchase orders, specifications, invoices, origin records, and communications showing how you determined whether the merchandise was covered.
