7409.39 - Other:

This category, HTS 7409.39, encompasses copper-tin base alloy (bronze) plates, sheets, and strip that exceed 0.15 mm in thickness and are not presented in coils. These items are distinct from their sibling category, HTS 7409.31, which specifically covers bronze plates, sheets, and strip in coiled form. The crucial differentiating factor is the presentation of the material; goods classified here are typically flat, continuous pieces that are cut to specific lengths rather than being wound onto a core.

Within this broad classification, further distinctions are made based on the thickness of the bronze material. The subcategories provided allow for a more precise classification by dividing the remaining material into those with a thickness of 5 mm or more and those with a thickness of less than 5 mm. This granular approach to thickness is vital for customs purposes, often reflecting variations in manufacturing processes, intended end-uses, and potentially different tariff rates or regulatory requirements associated with these physical properties.
