7409.90.50.30 - Of beryllium copper

This HTS category, 7409.90.50.30, specifically classifies copper plates, sheets, and strip that are made of beryllium copper alloys. These materials must exceed 0.15 mm in thickness, be less than 5 mm in thickness, and have a width of 500 mm or more. Beryllium copper is a specific alloy known for its unique properties, such as high strength, conductivity, and resistance to corrosion and wear, making it suitable for specialized applications.

This classification is distinguished from its sibling category, 7409.90.50.60 ("Other"), by the precise material composition. While the "Other" category would encompass copper alloys that do not fit the specific definition of beryllium copper, this subcategory is dedicated solely to products made from this particular alloy. This distinction is crucial for accurately applying customs duties and trade statistics based on the material's inherent characteristics and market value.

As this is a leaf node within the HTS, there are no further subcategories. Therefore, the focus for classification within this code is on verifying the material composition (beryllium copper), the physical dimensions (thickness exceeding 0.15 mm, less than 5 mm, and width of 500 mm or more), and ensuring the product is in the form of plates, sheets, or strip. This level of specificity ensures that only qualifying beryllium copper products are classified here, differentiating them from other copper alloys or copper products falling under different HTS codes.
