8538.90.81.40 - Metal contacts

This HTS classification, 8538.90.81.40, specifically covers "Metal contacts" that are designed for use with electrical switchgear, switchboards, panel boards, and distribution boards classified under headings 8535, 8536, or 8537. These metal contacts are crucial components responsible for establishing or breaking electrical circuits within these larger assemblies. They are typically made from conductive materials like copper, brass, or alloys thereof, and their design is optimized for electrical conductivity, durability, and resistance to arcing.

This specific subheading distinguishes itself from sibling categories by focusing exclusively on the metal contact components themselves. While 8538.90.81.60 covers broader "other parts" of switchgear, etc., this category isolates the discrete metal contacts. Furthermore, it is differentiated from 8538.90.81.80, which serves as a residual category for any other parts not specifically enumerated. Therefore, this classification is reserved for the actual conductive elements that facilitate electrical connections within the specified electrical apparatus.

As this is a leaf node within the HTS, there are no further subcategories. Classification under 8538.90.81.40 is determined by the material composition (metal) and the intended function as a contact within switchboards, panel boards, or distribution boards, aligning with the scope of Chapter 85 and the broader category for parts and accessories of electrical apparatus.
