Basic heading 87453 · $16.8M of $44.8B
Universal testing machines, hardness testers, tensile-strength rigs, and elasticity-measurement equipment used across metals, wood, textiles, and paper industries fall within this heading, reflecting their role as essential quality-assurance tools in manufacturing and materials research. The breadth of covered materials — from Rockwell and Brinell hardness testers for metals to tensile frames used in textile mills — means that the specific test method and material type are important factors when distinguishing this heading from other measuring or inspection equipment. Many of these machines are subject to Section 301 tariff considerations depending on country of origin, making origin documentation a routine compliance concern.

Hardness testers (Rockwell, Brinell, Vickers, Shore, etc.) are classified here because they measure a mechanical property of a material by applying a controlled force or indentation. Instruments that measure dimensional characteristics, surface finish, or optical properties are classified under different headings, so the physical principle of measurement is the key distinguishing factor.
Machines under this heading imported from origins subject to Section 301 tariffs may carry additional duties on top of the normal column 1 rate. Importers should verify the current Section 301 list status for the specific country of origin and HTS subheading before entry, as coverage and rates have been subject to ongoing review and modification.
