Porcelain bushings for voltage 6.6 kV or above but below 11 kV
Porcelain bushings, ceramic insulating fittings, 6.6 kV to below 11 kV
HSN 8547 10 20 (porcelain bushings for voltage 6.6 kV or above but below 11 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 within Chapter 85 — particularly those classified as insulators under heading 8546 — may carry distinct compliance obligations depending on voltage rating and intended application.
The boundary between insulating fittings (heading 8547) and insulators (heading 8546) is a recurring reclassification risk: customs officers examining the goods may re-characterise a porcelain bushing as a high-voltage insulator, triggering retrospective compliance applicable to that heading. Voltage rating, dimensional specification, and end-use documentation should be retained to defend classification at the 8547 line. Detention pending reclassification and retrospective duty recovery are the principal exposure where classification is disputed.
