U.S. imports of Electrical Insulators of Ceramics (HS 854620) totaled $19.9M in August 2026, imported from 36 countries.
Importers of Electrical Insulators of Ceramics paid $5.5M in duties in August 2026, an average duty rate of 27.86% — duty actually collected as a share of the imports that cleared customs, not the published tariff schedule. Electrical Insulators of Ceramics imports of $19.9M in August 2026 ran 22% above the year-to-date monthly average of $16.3M.
Last updated: August 2026 dataCeramic electrical insulators — encompassing porcelain pin-type, line-post, and high-voltage suspension types — are foundational components of transmission and distribution infrastructure worldwide. The US tariff schedule subdivides this heading by application: suspension/pin-type or line-post insulators (8546200030), high-voltage low-frequency ceramic insulators not elsewhere specified (8546200060), and all other ceramic insulators (8546200090). China and India are the dominant import sources, together accounting for the bulk of US supply; Brazil and Slovakia round out the supplier base. Section 301 tariffs apply to Chinese-origin ceramic insulators, a factor that has accelerated utility procurement diversification toward India and other suppliers.

Subheading 8546200030 covers suspension, pin-type, and line-post insulators — the most common distribution and transmission line types. Subheading 8546200060 captures high-voltage, low-frequency ceramic insulators that do not fit the pin/line-post description, such as certain station post or apparatus insulators. The NESOI line (8546200090) covers remaining ceramic insulators not meeting either prior description. Correct classification requires matching the insulator's design and voltage rating to the subheading definitions.
Because Chinese-origin ceramic insulators are subject to Section 301 tariffs, many US utilities and electrical contractors have shifted procurement toward India, which has expanded its ceramic insulator manufacturing capacity significantly. Importers should evaluate total landed cost — including Section 301 exposure — when comparing Chinese and Indian suppliers, and should verify origin documentation carefully given the complexity of ceramic component supply chains.
