8544.42 - Fitted with connectors:

This HTS category, 8544.42, specifically encompasses insulated electrical conductors that are designed for voltages not exceeding 1,000 volts and are fitted with connectors. This includes a wide array of cables and wires where electrical continuity is established through pre-attached connectors, facilitating easy and reliable connections in various electrical systems. The presence of these connectors is the defining characteristic for classification under this heading.

In contrast to its sibling category, 8544.49 (Other), which covers insulated conductors not fitted with connectors, this heading requires the explicit presence of terminating connectors. While both fall under the broader scope of insulated electric conductors for a voltage not exceeding 1,000 V, the key differentiator lies in the assembly and preparedness for direct interconnection that the fitted connectors provide.

The subcategories within 8544.42 further refine the classification based on the type of connector. For instance, 8544.42.10.00 specifically addresses items fitted with modular telephone connectors, highlighting a particular application. The broader "Other" subcategory is reserved for insulated conductors with connectors that do not fall into more specific connector types, ensuring comprehensive coverage within this group.
