On 01/23/2026, Commerce published in the Federal Register its antidumping duty order on overhead door counterbalance torsion springs from the People's Republic of China (91 FR 2911).

Plain-English explanation

CSMS 6029402 is a U.S. Customs and Border Protection (CBP) Cargo Systems Messaging Service bulletin (trade policy), published on January 29, 2026. It carries the official CBP guidance brokers and importers must follow for the topic — "On 01/23/2026, Commerce published in the Federal Register its antidumping duty order on overhead door counterbalance torsion springs from the People's Republic of China (91 FR 2911).". It links to 1 AD/CVD case in Tandom's catalog. CSMS messages are the operational layer between Commerce determinations and at-the-border collections: when Commerce publishes a new rate, scope ruling, or instruction, CBP turns it into a CSMS that ACE/ACS systems and brokers act on.

1. On 01/23/2026, Commerce published in the Federal Register its antidumping duty order on overhead door counterbalance torsion springs from the People's Republic of China (91 FR 2911). 2. The merchandise covered by this investigation is helically-wound, overhead door counterbalance torsion steel springs (overhead door counterbalance torsion springs) and any cones, plugs or other similar fittings for mounting and creating torque in the spring (herein collectively referred to as cones) attached to or entered with and invoiced with the subject overhead door counterbalance torsion springs. Overhead door counterbalance torsion springs are helical steel springs with tightly wound coils that store and release mechanical energy by winding and unwinding along the spring's axis by an angle, using torque to create a lifting force in the counterbalance assembly typically used to raise and lower overhead doors, including garage doors, industrial rolling doors, warehouse doors, trailer doors, and other overhead doors, gates, grates, or similar devices. The merchandise covered by this investigation covers all overhead door counterbalance torsion springs with a coil inside diameter of 15.8 millimeters (mm) or more but not exceeding 304.8 mm (measured across the diameter from inner edge to inner edge); a wire diameter of 2.5 mm to 20.4 mm; a length of 127 mm or more; and regardless of the following characteristics: wire type (including, but not limited to, oil-tempered wire, hard-drawn wire, music wire, galvanized or other coated wire); wire cross-sectional shape (e.g., round, square, or other shapes); coating (e.g., uncoated, oil- or water-based coatings, lubricant coatings, zinc, aluminum, zinc-aluminum, paint or plastic coating, etc.); winding orientation (left-hand or right-hand wind direction); end type (including, but not limited to, looped, double looped, clipped, long length, mini warehouse, Barcol, Crawford, Kinnear, Wagner, rolling steel or barrel ends); and whether the overhead door counterbalance torsion springs are fitted with hardware, including but not limited to fasteners, clips, and cones (winding or stationary cones). For purposes of the diameters referenced above, where the nominal and actual measurements vary, a product is within the scope if application of either the nominal or actual measurement would place it within the scope based on the definitions set forth above. The steel torsion springs included in the scope of this investigation are produced from steel in which: (1) iron predominates, by weight, over each of the other contained elements; and (2) the carbon content is 2 percent or less, by weight. Subject merchandise includes cones attached to or entered with and invoiced with the subject overhead door counterbalance torsion springs. Such cones, which are typically cast aluminum, aluminum alloy or steel (but may be made from other materials) are made to mount the subject springs to the overhead door counterbalance system and create and maintain torque in the spring. Cones or other similar fittings that are not attached to the subject springs or are not entered with and invoiced with the subject springs are not included within the scope unless entered as parts of kits as described below. Subject merchandise also includes all subject overhead door counterbalance torsion springs and cones or other similar fittings for mounting and tensioning the spring entered as a part of overhead door kits, overhead door mounting or assembly kits, or as a part of a spring-operated motor assembly or as a part of a spring winder assembly kit for torsion springs. When counterbalance torsion springs and cones or other similar fittings for attaching and tensioning the torsion spring are entered as a part of such kits, only the counterbalance spring and cones or other similar fittings in the kit are within scope. Subject merchandise also includes overhead door counterbalance torsion springs that have been further processed in a third country, including but not limited to cutting to length, attachment of hardware, cones or end-fittings, inclusion in garage door kits or garage door mounting or assembly kits, or any other processing that would not remove the merchandise from the scope of this investigation if performed in the country of manufacture of the in-scope overhead door counterbalance torsion springs. All products that meet the written physical description are within the scope of this investigation unless specifically excluded. The following products are specifically excluded from the scope of this investigation: leaf springs (slender arc-shaped length of spring steel of a rectangular cross-section); disc springs (conical springs consisting of a convex disc with the outer edge working against the center of the disc); extension springs (close-wound round helical wire springs that store and release energy by resisting the external pulling forces applied to the spring's ends in the direction of its length); compression springs (helical coiled springs with open wound active coils (such open winding is also known as pitch) that are designed to compress under load or force); and spiral springs (torsion springs wound as concentric spirals such as a clock spring or mainspring). The products subject to this investigation are currently classified under Harmonized Tariff Schedule of the United States (HTSUS) subheadings 7320.20.5020, 7320.20.5045, and 7320.20.5060. They may also be classified under HTSUS subheading 8412.90.9085 if entered as parts of spring-operated motors. They may also be classified in HTSUS subheading 8412.80.1000 (spring-operated motors) if entered as part of a spring counterweight assembly for an overhead door. They may also be classified in HTSUS subheading 7308.90.9590, a basket category that includes metal garage doors entered with mounting accessories or assemblies. Although the HTSUS subheadings are provided for convenience and customs purposes, the written description of the scope of this investigation is dispositive. 3. For imports of overhead door springs from the People's Republic of China, CBP shall suspend liquidation of entries of subject merchandise entered, or withdrawn from warehouse, for consumption on or after 10/02/2025 (the date on which the International Trade Commission published its final determination in the Federal Register). Effective 10/02/2025, CBP shall require a cash deposit equal to the percentages for the exporter/producer combinations identified below. These cash deposit rates have been adjusted to reflect the appropriate subsidy offsets determined in the companion countervailing duty proceeding.
