U.S. exports of machines & appliances for testing hardness, strength, compressibility & other material properties (nesoi) (HS 902480) totaled $28.7M in July 2026.
Importers of Machines & Appliances for Testing Hardness, Strength, Compressibility & Other Material Properties (NESOI) paid $1.0M in duties in July 2026 — an effective duty rate of 12% on $8.7M in dutiable value, based on actual customs collections rather than the published tariff schedule. Machines & Appliances for Testing Hardness, Strength, Compressibility & Other Material Properties (NESOI) imports of $10.0M in July 2026 ran 19% above the year-to-date monthly average of $8.5M.
Last updated: July 2026 dataCovering material testing equipment not dedicated to metals — including hardness testers for plastics, rubber, composites, and ceramics, as well as compression and elasticity testing rigs — this heading (9024800000) serves quality-control labs across the polymer, construction, and electronics industries. Germany and the United Kingdom are the top suppliers, reflecting the concentration of precision metrology manufacturing in those markets, with Italy and Canada also notable sources. Importers should distinguish carefully between this heading and 9024.10 (metals-specific testers), as the classification affects duty treatment and any applicable trade-remedy exposure.

351 shipments/mo
Rockwell testers designed and marketed specifically for metals — the most common configuration — fall under 9024.10. A Rockwell-type instrument adapted for plastics or rubber (using different indenters and load scales per ASTM D785, for example) would fall under 9024.80 as a non-metals hardness tester. The manufacturer's specifications and the applicable test standards cited in product documentation are the primary classification evidence.
Goods of Canadian or Mexican origin that meet USMCA rules of origin may qualify for preferential duty treatment under that agreement. For equipment sourced from Germany, Italy, or the United Kingdom, no comparable US free-trade-agreement preference is currently available, so the general MFN rate applies.
