7409.39.90.30 - Of phosphor bronze

This HTS classification, 7409.39.90.30, specifically designates copper plates, sheets, and strip made from phosphor bronze alloys. These materials are characterized by their copper-tin base, further alloyed with phosphorus, imparting enhanced properties such as high tensile strength, resilience, and corrosion resistance. The dimensions of these goods are further refined to be of a thickness exceeding 0.15 mm, a width of less than 500 mm, and a thickness of less than 5 mm, as established by the preceding hierarchical levels.

This particular subheading distinguishes itself from its sibling category, 7409.39.90.60 ("Other"), by the specific composition of the alloy. While both subheadings fall under "Other" within the broader "Of copper-tin base alloys (bronze)" classification and share the same dimensional criteria, 7409.39.90.30 is exclusively for phosphor bronze. The sibling category would encompass other types of bronze not specifically identified elsewhere within the tariff schedule that meet the specified dimensions.

As this is a leaf node in the HTS classification structure, there are no further subcategories to introduce. Therefore, classification within 7409.39.90.30 is final for qualifying phosphor bronze plates, sheets, and strip meeting all the specified physical and compositional criteria. Importers and exporters should ensure accurate documentation confirming the alloy composition as phosphor bronze to ensure correct classification and compliance.
