U.S. exports of Insulated Coaxial Cable & Coaxial Electrical Conductors (HS 854420) totaled $67.5M in August 2026.
Importers of Insulated Coaxial Cable & Coaxial Electrical Conductors paid $8.0M in duties in August 2026, an average duty rate of 15.26% — duty actually collected as a share of the imports that cleared customs, not the published tariff schedule. Insulated Coaxial Cable & Coaxial Electrical Conductors imports of $54.5M in August 2026 ran 11% above the year-to-date monthly average of $49.0M.
Last updated: August 2026 dataCoaxial cable's concentric conductor geometry — a central conductor, dielectric insulator, outer shield, and jacket — defines its classification here and distinguishes it from other insulated conductors in heading 8544. The heading covers the full range of coaxial products used in RF signal transmission, broadband infrastructure, and defense electronics, all consolidated under a single 10-digit line (8544200000). Mexico is the dominant US import source, with China and Vietnam also supplying significant volumes. Coaxial cable sourced from China is subject to Section 301 tariffs, a cost factor that has contributed to supply-chain diversification toward Mexico and Vietnam.

Classification as coaxial cable requires the concentric construction: a central conductor surrounded by a dielectric, then a conductive shield (braid, foil, or combination), and an outer jacket. Cables lacking this coaxial geometry — even if used for signal transmission — are classified under other 8544 subheadings based on voltage rating and connector configuration.
No. The US schedule consolidates all insulated coaxial cable and coaxial electrical conductors into a single 10-digit line (8544200000), regardless of impedance, frequency rating, or application. Classification disputes in this heading typically center on whether the product meets the coaxial construction definition rather than on which sub-line applies.
