The Harmonized Tariff Schedule separates primary wood-processing equipment (e.g., log debarkers, frame saws used in sawmills) from secondary woodworking machinery (e.g., planers, mortisers, tenoners used in furniture or joinery production). The distinction matters because the applicable HTS headings and duty rates can differ, and misclassification is a common audit finding for importers of multi-function wood processing lines.

Certain paper and pulp machinery components sourced from China may be subject to Section 301 tariffs depending on their specific HTS classification. Importers should review each line item individually, as a complete paper machine and its separately imported spare parts may fall under different tariff treatments.
