At the 6-digit and 10-digit level, heading 8714.20 / 8714200000 covers parts for both manual and powered invalid carriages without distinction. However, the commercial invoice should clearly describe the intended parent article, as CBP may use that information to assess whether the part is correctly classified here versus under a more specific heading for motorized vehicle parts.

For Mexican-origin parts, a USMCA certification of origin from the producer or exporter is the primary document needed to claim preferential treatment. Supporting records should include a detailed parts description, the HTS number, and evidence of origin such as bills of materials or production records. Mexico is a leading supplier under this heading, so USMCA qualification is a routine cost-saving opportunity worth verifying.
