8544.20.00.00 - Coaxial cable and other coaxial electric conductors

HTS Code 8544.20.00.00 specifically classifies coaxial cables and other coaxial electric conductors. Coaxial cable is characterized by its inner conductor, surrounded by an insulating layer, then by a braided metal shield, and finally by an outer insulating jacket. This construction allows for efficient transmission of high-frequency electrical signals with minimal loss and interference, making it ideal for applications such as telecommunications, television signal distribution, and data networking.

This classification is distinct from its sibling categories. For instance, it is differentiated from "winding wire" which is designed for use in coils and transformers. It also differs from "ignition wiring sets and other wiring sets of a kind used in vehicles, aircraft or ships" (8544.30.00.00) by not being a pre-assembled set for specific automotive or marine applications. Furthermore, it is separate from other insulated electric conductors for voltages not exceeding 1,000 V and those exceeding 1,000 V (8544.60), as it specifically addresses the unique construction and signal transmission properties of coaxial configurations. Finally, it is distinguished from "optical fiber cables" (8544.70.00.00), which transmit data using light signals rather than electrical signals.

As a leaf node, HTS 8544.20.00.00 does not have further subcategories. Therefore, classification within this code relies on identifying articles that meet the definition of coaxial cable or other coaxial electric conductors, typically based on their distinctive layered structure designed for high-frequency signal transmission and their use in related technological fields. Examples include RG-6, RG-59, and LMR series cables used for antenna connections and broadband internet.
