HS Code 8546.90 – Electrical insulators; other than of glass and ceramics

HS code 8546.90 is the 6-digit subheading for electrical insulators, other than of glass and ceramics. It is used for composite suspension insulators, silicone rubber insulators, polymer line post insulators, epoxy resin insulators and FRP insulators.

What HS 8546.90 covers

This residual HS code covers electrical insulators made from materials other than glass or ceramics, encompassing a growing range of advanced polymer composites and other synthetic materials. These "other" insulators are increasingly popular due to their lightweight nature, superior hydrophobicity, resistance to vandalism, and excellent performance in polluted environments, often outperforming traditional materials in specific applications. They are widely used in modern power transmission lines, railway systems, and specialized industrial electrical equipment. Importers include countries seeking to upgrade their grid infrastructure with lighter, more resilient materials, or those with specific environmental challenges, such as the USA, Canada, and parts of Europe. Exporters are typically nations with advanced chemical and materials science industries, capable of producing sophisticated polymer composites, with China, Germany, and the USA being key players. Key trade considerations include the material's UV resistance, tracking and erosion resistance, mechanical strength, and long-term reliability under various climatic conditions.

Codes often confused with 8546.90

Common mistake. This code is for insulators not made of glass (854610) or ceramics (854620); misclassification occurs if the material is not correctly identified as a polymer or composite, or if it's mistaken for an insulating fitting under 8547.

Top exporters and importers of HS code 854690, 2025

In 2025, the largest exporter of HS code 854690 in UN Comtrade data was China, with 24% of world exports; the largest importer in UN Comtrade data was the United States, with 14% of world imports. Countries that did not report 2025 data are estimated from partner records, which can understate them.

How these figures are built

109 countries reported 2025 trade to UN Comtrade in HS 2022, and their own totals are used. Countries that did not report are estimated from what other countries recorded trading with them. Those estimates miss trade with other non-reporting countries, so they can be low, and a non-reporting country can rank higher than shown or be missing from the list. World totals add both and leave out trade between two non-reporting countries. Figures are in current US dollars; reported imports are mostly valued CIF and exports FOB, and exports include re-exports. The UN Comtrade links show the underlying records; they can also list a few reporters left out here (regional groups and older HS editions).
