Scope text

Legally operative description of covered merchandise from the Federal Register

The products covered by this order are circular welded non-alloy steel pipes and tubes, of circular cross-section, not more than 406.4 millimeters (16 inches) in outside diameter, regardless of wall thickness, surface finish (black, galvanized, or painted), or end finish (plain end, beveled end, threaded, or threaded and coupled). These pipes and tubes are generally known as standard pipes and tubes and are intended for the low pressure conveyance of water, steam, natural gas, and other liquids and gases in plumbing and heating systems, air conditioning units, automatic sprinkler systems, and other related uses, and generally meet ASTM A-53 specifications. Standard pipe may also be used for light load-bearing applications, such as for fence tubing, and as structural pipe tubing used for framing and support members for reconstruction or load-bearing purposes in the construction, shipbuilding, trucking, farm equipment, and related industries. Unfinished conduit pipe is also included in these orders. All carbon steel pipes and tubes within the physical description outlined above are included within the scope of this order, except line pipe, oil country tubular goods, boiler tubing, mechanical tubing, pipe and tube hollows for redraws, finished scaffolding, and finished conduit. Standard pipe that is dual or triple certified/stenciled that enters the U.S. as line pipe of a kind used for oil or gas pipelines is also not included in this order.

Frequently asked questions

What is AD/CVD case A-351-809?

A-351-809 is a U.S. antidumping duty (AD) order on circular welded pipe and tube from Brazil, issued by the U.S. Department of Commerce. It is part of the trade-remedy regime that levies cash deposits at entry on imports found to be sold below fair value (AD) or to benefit from foreign government subsidies (CVD).

What is the deposit rate for A-351-809?

A-351-809 has no published country-wide rate in Tandom's catalog at this time. Cash deposits are still owed at entry — the applicable rate depends on the specific manufacturer/exporter and the most recent administrative review. Check the linked Federal Register notice and the manufacturer rates for this case for the operative number.

Is AD/CVD case A-351-809 still active?

A-351-809 is on the U.S. AD/CVD register and is currently in active status — cash deposits apply at entry on every shipment in scope.

How do I check if my shipment falls within the scope of A-351-809?

Two factors determine scope: (1) the product's HTS code(s) and physical characteristics — covered codes are listed on this page (2 flagged); and (2) the product's country of origin — this order applies to imports from Brazil. The order's scope text — also on this page — is the legally binding description. When borderline cases arise, importers can request a formal scope ruling from Commerce. Tandom's lookup tool matches your HTS + origin against every active order in seconds.

What HTS codes are covered by A-351-809?

A-351-809 flags 2 HTS codes in Tandom's catalog. The full list is shown on this page. HTS coverage alone does not guarantee scope — physical-characteristic exclusions in the scope text may carve out specific products.

Where is the official Federal Register notice for A-351-809?

The official Federal Register citation for A-351-809 is 05-22241. The link is on this page; clicking it opens the canonical FR document on federalregister.gov, which carries the legally operative text — scope, rates, exclusions, and effective dates.
