Last updated: April 2026 dataGear drives, ball screws, gear boxes, and torque converters are foundational motion-control components in machine tools, robotics, wind turbines, and automotive drivetrains, making this one of the more widely traded mechanical-components headings. Ball screws in particular are precision-ground articles whose accuracy grade (C3 through C10) directly affects classification and pricing negotiations with suppliers. Section 301 tariffs apply to imports from certain origins, so supply-chain teams routinely evaluate alternative sourcing to manage landed cost.

While SITC 74840 does not subdivide by grade, the corresponding HTS subheadings may distinguish precision ball screws from standard ones. Accuracy grade (per ISO or JIS standards) also affects customs valuation because higher-grade screws command significantly different transaction values — importers should ensure invoices reflect the correct grade specification.
Imports from certain countries are subject to Section 301 tariffs at the HTS subheading level. The applicability depends on the specific 10-digit HTS code and the country of origin; importers should consult the USTR's Section 301 product lists and a licensed customs broker to confirm current exposure.
