HS Code 9024.90 – Machines and appliances; parts and accessories for those testing hardness, strength, compressibility, elasticity or other mechanical properties of materials (e.g. metal, wood, textiles, paper, plastics)
HS code 9024.90 is the 6-digit subheading for machines and appliances, parts and accessories for those testing hardness, strength, compressibility, elasticity or other mechanical properties of materials (e.g. metal, wood, textiles, paper, plastics). It is used for load cells, extensometers, grips and fixtures, hardness indenters and testing machine software.
What HS 9024.90 covers
This HS code covers the essential parts and accessories that enable the functionality, maintenance, and versatility of mechanical testing machines classified under 9024. These components are critical for ensuring the continuous operation, accuracy, and adaptability of equipment used to test metals, plastics, textiles, and other materials. Importers are typically service providers, testing laboratories, and manufacturers who perform in-house quality control, needing to repair, upgrade, or calibrate their existing machinery. Exporters are often the original equipment manufacturers (OEMs) or specialized component suppliers. The trade in these parts is vital for supporting global R&D efforts and quality assurance programs, ensuring the longevity and reliability of sophisticated material testing infrastructure.

How these figures are built
109 countries reported 2025 trade to UN Comtrade in HS 2022, and their own totals are used. Countries that did not report are estimated from what other countries recorded trading with them. Those estimates miss trade with other non-reporting countries, so they can be low, and a non-reporting country can rank higher than shown or be missing from the list. World totals add both and leave out trade between two non-reporting countries. Figures are in current US dollars; reported imports are mostly valued CIF and exports FOB, and exports include re-exports. The UN Comtrade links show the underlying records; they can also list a few reporters left out here (regional groups and older HS editions).
