Large Diameter Welded Carbon and Alloy Steel Line and Structural Pipe — Canada — A-122-863

This is an antidumping and countervailing duty (AD/CVD) trade measure covering certain large-diameter welded carbon and alloy steel line pipe and structural pipe. “Antidumping” addresses imports sold at less than normal value, while “countervailing” addresses benefits that a foreign government provides to producers or exporters. These measures are separate from ordinary customs duty and may apply in addition to it.

The measure typically affects importers, foreign producers, exporters, and sometimes specific countries or companies, depending on the scope of the order. Coverage is determined by the product’s physical characteristics and intended use—not just its invoice description or tariff classification. An importer should compare the merchandise carefully with the official scope, identify the applicable HTSUS classification, and confirm whether special company- or country-specific rules apply. AD/CVD liability can involve cash deposits, entry reporting, and later administrative review, so a customs broker or trade specialist may be needed.

What to check

• Read the official scope language and compare the pipe’s dimensions, steel composition, welding method, shape, and intended use—not only its product name.
• Confirm the correct HTSUS classification, but do not treat the tariff number as the sole test of coverage; scope language controls.
• Identify the actual foreign producer and exporter, and check whether the measure distinguishes among countries, companies, or suppliers.
• Ask your customs broker to verify the required AD/CVD entry information, cash-deposit treatment, and any certification or reporting requirements.
• Keep technical specifications, mill certificates, commercial invoices, and origin records that support your coverage and classification analysis.
