U.S. imports of textile finishing, coating, and impregnating machinery (HS 845180) totaled $4.9M in August 2026, imported from 27 countries.
Importers of Textile Finishing, Coating, and Impregnating Machinery paid $557K in duties in August 2026, an effective tariff rate of 11.30% of the $4.9M imported — duty actually collected as a share of that value, not the published tariff schedule. Textile Finishing, Coating, and Impregnating Machinery imports of $4.9M in August 2026 ran 25% above the year-to-date monthly average of $4.0M.
Last updated: August 2026 dataCoating lines, impregnation ranges, and finishing frames used to apply functional treatments — waterproofing, flame retardancy, or lamination — to yarns, fabrics, and made-up articles classify under 8451800000 as the residual machinery line within heading 8451. Mexico and South Korea are the leading US import sources for this equipment, with Germany supplying high-specification coating lines for technical textile applications. Importers of Chinese-origin machinery in this category should assess Section 301 exposure, as coating and finishing equipment has been included in successive Section 301 lists.

The key distinction is the intended substrate: 845180 covers machines specifically designed to finish, coat, or impregnate textile yarns, fabrics, or made-up articles. Coating machines designed for paper, plastics, or other non-textile substrates would classify under different headings in Chapter 84. When a machine is marketed as multi-substrate capable, the principal use or design intent typically governs classification.
Beyond standard CBP entry documents, a solvent-based impregnation machine may require EPA review if it incorporates components that handle ozone-depleting substances or regulated solvents. Importers should also confirm whether the machine's electrical specifications require UL or equivalent certification for installation in US facilities. A licensed customs broker and the equipment manufacturer's compliance team can help identify applicable requirements.
