Continuous automatic centrifuges
Continuous automatic centrifuges for industrial separation
HSN 8421 19 30 (Continuous automatic centrifuges) 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, bill of entry, commercial invoice, packing list. Other centrifuge and filtration equipment within Chapter 84 — particularly units intended for specific end-uses such as dairy processing, pharmaceutical manufacture, or hazardous-fluid handling — may fall under sibling tariff lines or sector-specific compliance regimes.
The absence of compliance at this tariff line does not extend to all centrifuge classifications: units classified under different subheadings within heading 8421 — such as centrifugal dryers or gas-filtration apparatus — may attract distinct requirements depending on end-use and sector. Re-classification on customs examination triggers retrospective compliance, including detention pending the relevant determination. Verify the precise product specification — continuous versus batch operation, intended process fluid, and output capacity — against the customs tariff before relying on the absence of compliance.
