HS code for Ceramic insulating fitting: 8547.10

Insulating fittings, of ceramics, for electrical machines, of insulating material only (except minor assembly parts), excluding those of heading no. 8546.

Classification of ceramic insulating fitting under HS 8547.10

Ceramic insulating fittings are classified under HS code 854710. This classification is governed by the rules of Chapter 85, which encompasses electrical machinery and equipment. While Chapter 69 generally covers ceramic products, the Harmonized System dictates that articles specifically designed for electrical insulation within machinery or appliances are classified under heading 8547. To qualify for 854710, the fitting must be made entirely of insulating material, such as ceramic, except for minor metal components like threaded inserts or bolts used solely for assembly. These fittings are integral components of electrical devices, providing the necessary dielectric strength to prevent short circuits and ensure user safety. The classification is based on the item's function as a component of an electrical assembly rather than its material alone. These fittings are often found in industrial ovens, heaters, and complex electrical control panels where high-temperature resistance and electrical isolation are required simultaneously. The ceramic material used is often selected for its ability to resist thermal shock and maintain its insulating properties even when exposed to extreme heat or corrosive environments.

Codes often confused with 8547.10

Common mistake. A frequent point of confusion occurs between HS code 854710 and HS code 854620. While both involve ceramic electrical insulation, 854620 is specifically for electrical insulators, which are typically standalone components used in power transmission and distribution lines, such as suspension or pin insulators. In contrast, 854710 is for insulating fittings, which are designed to be incorporated into specific machines or appliances. Another common misclassification is under 690911, which covers ceramic wares for laboratory or chemical uses. If a ceramic part is used for insulation in an electrical context, 854710 takes precedence over general ceramic headings in Chapter 69.

Top exporters and importers of HS 854710 (the code used for ceramic insulating fitting), 2025

In 2025, the largest exporter of HS 854710 (the code used for ceramic insulating fitting) in UN Comtrade data was China, with 31% of world exports; the largest importer in UN Comtrade data was China, with 15% of world imports. Countries that did not report 2025 data are estimated from partner records, which can understate them.

Figures cover everything classified under HS 854710, not only ceramic insulating fitting.

How these figures are built

109 countries reported 2025 trade to UN Comtrade in HS 2022, and their own totals are used. Countries marked * did not, so their figures add up what other countries recorded trading with them, and their exports are valued at buyers' CIF prices. 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. UN Comtrade records Taiwan as "Other Asia, not elsewhere specified". Saudi Arabia's exports under that code are left out: they are far too large to be trade with Taiwan, so mostly undisclosed partners. 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).
