Chapter 84 HS codes for machinery, computers and printers
Browse 2026 Chapter 84 headings for machinery, computers, printers and related parts. The machine’s principal function, configuration, and whether it is complete or a part can determine the final U.S. HTS line.
Separate machines from parts
A component is not automatically classified with the finished machine. Review the section notes, dedicated parts provisions, and whether the item is itself a complete article described elsewhere.
