8544.42.20.00 - Of a kind used for telecommunications

This HTS classification, 8544.42.20.00, specifically covers insulated electric conductors, such as wires and cables, designed for use in telecommunications systems and rated for a voltage not exceeding 1,000 volts. The key distinguishing feature of this category is that the conductors are *fitted with connectors*. This implies that the wires or cables have been pre-assembled with plugs, sockets, terminals, or other connecting devices, making them ready for direct integration into telecommunications equipment without requiring further connection work at the point of use.

This category is distinct from its sibling, 8544.42.90, which covers other electric conductors for telecommunications that are *not* fitted with connectors. The presence or absence of attached connectors is the primary determinant for distinguishing between these two subheadings. Therefore, if an insulated conductor intended for telecommunications has permanently affixed connectors, it falls under 8544.42.20.00. If it does not have such connectors, even if designed for the same purpose, it would be classified under 8544.42.90.

As this is a leaf node within the HTS structure, there are no further subcategories to introduce. The classification is complete at this level, based on the criteria of being an insulated electric conductor, intended for telecommunications, operating at a voltage not exceeding 1,000 V, and importantly, being fitted with connectors. Examples within this classification would include pre-made patch cords for network infrastructure, telephone cords with attached modular plugs, or specialized cables for connecting telecommunications equipment that come with integrated end fittings.
