The U.S. International Trade Commission instituted Investigation No. 337-TA-1491 on March 9, 2026, targeting certain vehicle parts and components that allegedly infringe 20 General Motors design patents. Trade compliance engineering teams managing automotive component imports should immediately flag related HTS classifications pending the investigation's outcome, as the complainants are seeking both general and limited exclusion orders that could halt affected goods at the border.
General Motors LLC and GM Global Technology Operations LLC, both headquartered in Detroit, Michigan, filed the underlying complaint on February 5, 2026, under Section 337 of the Tariff Act of 1930 (19 U.S.C. 1337). The complaint targets the importation, sale for importation, and post-importation sale within the United States of vehicle parts that allegedly copy GM's protected designs.
Patents at Issue
The investigation covers 20 specific U.S. Design Patents: D749,997; D792,815; D792,816; D793,301; D828,247; D828,248; D828,256; D847,703; D848,318; D856,874; D818,406; D826,114; D843,025; D883,155; D902,807; D930,533; D955,939; D859,239; D848,647; and D826,803. Each patent protects the ornamental design of specific vehicle components, likely covering aftermarket body panels, grilles, lighting assemblies, and similar replacement parts commonly imported from overseas manufacturers.
The ITC is investigating potential violations under 19 U.S.C. 1337(a)(1)(B), which prohibits unfair acts in the importation of articles that infringe valid U.S. patents. Under 19 CFR 210.10 (2025), the Commission determined sufficient grounds exist to proceed with a full investigation. GM has alleged that a domestic industry exists or is being established, satisfying the statutory requirement for Section 337 relief.
Compliance Impact
If the ITC issues a general exclusion order, U.S. Customs and Border Protection will block all articles covered by the order regardless of source or importer. A limited exclusion order would target specific respondents. Either remedy would require compliance systems to validate automotive parts shipments against the exclusion scope before clearance. Teams relying on cached HTS rate data should prepare for potential exclusion order overlays on classifications covering motor vehicle body parts (typically HTS Chapter 87 subheadings).
Section 337 investigations typically take 12 to 18 months to reach a final determination. However, preliminary relief is possible, and importers should monitor EDIS (the Commission's Electronic Document Information System at edis.usitc.gov) for procedural updates. The Office of Unfair Import Investigations contact for this matter is Pathenia M. Proctor at (202) 205-2560.
For trade compliance engineering teams, this investigation underscores the need for real-time monitoring of ITC exclusion orders alongside standard tariff rate updates. Aftermarket automotive parts represent a high-volume import category where design patent disputes increasingly drive enforcement actions. Systems that cannot cross-reference exclusion orders against HTS classifications risk clearance delays and potential penalties for importing prohibited merchandise.
