8544.42.10.00 - Fitted with modular telephone connectors

This HTS subheading covers insulated electrical conductors, specifically wires and cables, designed for voltages not exceeding 1,000 volts. The key defining characteristic for classification under 8544.42 is that these conductors are **fitted with modular telephone connectors**. This includes a wide array of cables and wires that have been pre-terminated with standard telephone plugs, facilitating their direct connection to telecommunication devices or networks.

This category is distinguished from its sibling, 8544.42.90 (Other), by the specific type of connector attached. While 8544.42.90 would encompass insulated conductors fitted with various other types of connectors (e.g., power plugs, audio jacks, specialized data connectors), 8544.42.10 is exclusively for those equipped with connectors designed for modular telephone interfaces. The presence and type of these modular telephone connectors are the primary classification criteria at this level.

As a leaf node, this subheading does not contain further subdivisions. Therefore, classification into this category relies solely on meeting the criteria of being an insulated electrical conductor for a voltage not exceeding 1,000 volts and being fitted with modular telephone connectors. Examples include patch cords for telephone systems, extension cords with telephone plugs, and pre-wired assemblies for telecommunication equipment where modular telephone connectors are integrated.
