9024.90.00.40 - Of machines and appliances for testing metals 🖩

This classification, HTS Code 9024.90.00.40, specifically covers parts and accessories that are designed for use with machines and appliances intended for the testing of metals. These machines and appliances are used to determine mechanical properties such as hardness, strength, compressibility, and elasticity. Therefore, any component or accessory solely manufactured or principally used in conjunction with such metal-testing apparatus falls under this heading. Examples include specialized grips, probes, anvils, or other fixtures integral to the operation of metal testing machines.

This category is distinguished from its sibling, 9024.90.00.80 "Other," by its exclusive focus on metal-testing equipment. While both are parts and accessories for machines under HTS 9024, this specific subheading requires a direct nexus to the testing of metals. If a part or accessory is designed for a broader range of material testing, or for machines that test materials other than metals (e.g., wood, textiles, paper, plastics), it would likely be classified under the "Other" residual category. The intended application and design of the part are paramount for correct classification.

As this is a leaf node, there are no further subcategories within HTS 9024.90.00.40. Classification decisions within this specific heading will rely on the precise nature of the part or accessory and its confirmed association with metal-testing machinery. Customs officers will examine the product's specifications, design, and stated purpose to ensure it aligns with the established criteria for this classification.
