Last updated: July 2026 dataWork holders — including chucks, collets, vises, fixtures, and magnetic chucks — secure workpieces during machining and are critical determinants of part accuracy and repeatability on lathes, mills, and grinding machines. Unlike tool holders, which grip the cutting tool, work holders grip the part being machined, and the distinction matters for correct classification. Precision work-holding equipment is a high-value segment of the machine-tool accessories market, with demand driven by aerospace, medical-device, and automotive precision-machining operations.

Basic heading 73513 · $39.4M of $175.6B
Work holders (73513) grip the workpiece being machined — examples include lathe chucks, collets, vises, and magnetic chucks. Tool holders (73511) grip the cutting tool. The distinction is functional: if the item holds the part, it is a work holder; if it holds the cutter, it is a tool holder. Misclassifying between these two headings is a common error on entry documents for machine-tool accessories.
Work holders sourced from certain countries — particularly China — may be subject to Section 301 tariffs. Antidumping orders have historically covered some categories of precision chucks and vises. Importers should check current CBP and USTR guidance for the applicable HTS subheading and country of origin before finalizing sourcing decisions.
