Porcelain bushings for voltage 11 kV or above but upto 66 kV
Porcelain bushings for electrical insulation, 11 kV to 66 kV
HSN 8547 10 30 (porcelain bushings for voltage 11 kV or above but up to 66 kV) is not covered by a Bureau of Indian Standards Quality Control Order and carries no Partner Government Agency clearance requirement at the tariff-line level. Import follows the standard customs procedure: Importer-Exporter Code (IEC), bill of entry, commercial invoice, packing list. Other ceramic insulating fittings under Chapter 85, including those rated above 66 kV or classified as stand-alone insulators under heading 8546, may fall under separate compliance obligations.
The principal risk for this tariff line is misclassification: porcelain insulators of heading 8546 are a distinct product family and carry their own compliance regime, and customs re-examination that shifts a consignment from 8547 to 8546 — or to a higher-voltage bushing sub-heading — triggers retrospective compliance including detention pending the relevant certificate. Importers should confirm the voltage rating, ceramic grade, and assembly configuration in technical documentation before declaration, as minor design differences can move the product across headings.
