8544.49.30 - Of copper

This HTS classification, 8544.49.30, specifically covers insulated electric conductors made of copper, intended for use with a voltage not exceeding 1,000 V. These are the "other" conductors within the broader category of insulated wire and cable for voltages up to 1,000 V, excluding those specifically identified by other subheadings. The defining characteristic is their copper composition and their application for lower voltage electrical current transmission.

This category is distinguished from its sibling, 8544.49.90.00, by the material composition. While this subheading is reserved for copper conductors, the sibling subheading encompasses insulated electric conductors made from other materials. Therefore, the presence of copper as the primary conductor material is the key differentiating factor.

The subcategories within 8544.49.30 further refine the classification based on the specific voltage rating they are designed for. 8544.49.30.40 applies to those copper conductors rated for voltages exceeding 600 V (but still within the overall 1,000 V limit), while 8544.49.30.80 captures the remaining copper conductors operating at voltages up to and including 600 V. This distinction is crucial for accurately classifying based on electrical performance parameters.
