Electro-chemical machines
Electro-chemical machine tools for material removal
HSN 8456 90 20 (Electro-chemical machines) 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 machine-tools classified within Chapter 84 — particularly those incorporating laser, electron-beam, or electro-discharge processes — may fall under sibling tariff lines with distinct compliance obligations; precise process-type classification is the principal importer risk.
Heading 8456 covers several discrete material-removal technologies, each with its own 8-digit tariff line; electro-discharge, laser, and electron-beam machines are separately enumerated and may attract compliance under a Quality Control Order applicable to that specific process type. Customs re-classification from the electro-chemical line to a more specific process-type line triggers retrospective compliance, including potential detention pending re-assessment. Importers should verify the machine's primary material-removal process against the tariff schedule before finalising the bill of entry.
