Scope text

Legally operative description of covered merchandise from the Federal Register

The scope of this order covers certain freight railcar couplers (also known as "fits" or "assemblies") and parts thereof. Freight railcar couplers are composed of two main parts, namely knuckles and coupler bodies but may also include other items (e.g., coupler locks, lock lift assemblies, knuckle pins, knuckle throwers, and rotors). The parts of couplers that are covered by the order include: (1) E coupler bodies, (2) E/F coupler bodies, (3) F coupler bodies, (4) E knuckles, and (5) F knuckles, as set forth by the Association of American Railroads (AAR). The freight rail coupler parts (i.e., knuckles and coupler bodies) are included within the scope of the order when imported separately. Coupler locks, lock lift assemblies, knuckle pins, knuckle throwers, and rotors are covered merchandise when imported in an assembly but are not covered by the scope when imported separately. Subject freight railcar couplers and parts are included within the scope whether finished or unfinished, whether imported individually or with other subject or nonsubject parts, whether assembled or unassembled, whether mounted or unmounted, or if joined with nonsubject merchandise, such as other nonsubject parts or a completed railcar. Finishing includes, but is not limited to, arc washing, welding, grinding, shot blasting, heat treatment, machining, and assembly of various parts. When a subject coupler or subject parts are mounted on or to other nonsubject merchandise, such as a railcar, only the coupler or subject parts are covered by the scope. The finished products covered by the scope of this order meet or exceed the AAR specifications of M-211, "Foundry and Product Approval Requirements for the Manufacture of Couplers, Coupler Yokes, Knuckles, Follower Blocks, and Coupler Parts" and/or AAR M-215 "Coupling Systems," or other equivalent domestic or international standards (including any revisions to the standard(s)). The country of origin for subject couplers and parts thereof, whether fully assembled, unfinished or finished, or attached to a railcar, is the country where the subject coupler parts were cast or forged. Subject merchandise includes coupler parts as defined above that have been further processed or further assembled, including those coupler parts attached to a railcar in third countries. Further processing includes, but is not limited to, arc washing, welding, grinding, shot blasting, heat treatment, painting, coating, priming, machining, and assembly of various parts. The inclusion, attachment, joining, or assembly of nonsubject parts with subject parts or couplers either in the country of manufacture of the in-scope product or in a third country does not remove the subject parts or couplers from the scope.

Frequently asked questions

What is AD/CVD case A-570-145?

A-570-145 is a U.S. antidumping duty (AD) order on certain freight rail couplers and parts from china from China, 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-570-145?

The country-wide cash deposit rate for A-570-145 is 139.49%. This rate applies to importers of non-listed manufacturers/exporters from China.

When did A-570-145 take effect, and is it still active?

A-570-145 took effect on November 27, 2023 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-570-145?

Two factors determine scope: (1) the product's HTS code(s) and physical characteristics — covered codes are listed on this page (9 flagged); and (2) the product's country of origin — this order applies to imports from China. 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-570-145?

A-570-145 flags 9 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-570-145?

The official Federal Register citation for A-570-145 is 2023-14892. 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.

What is the companion case for A-570-145?
