Magnetrons
Magnetrons, vacuum electron devices for microwave generation
HSN 8540 71 00 (Magnetrons) 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 thermionic and microwave tube types classified elsewhere within Chapter 85 may carry compliance obligations; classification accuracy against the precise device type is the principal importer risk.
The absence of compliance at this tariff line does not extend to downstream applications: magnetrons incorporated into microwave ovens or radar equipment may trigger product-level compliance under Quality Control Orders applicable to the finished assembly classified in a different heading. Re-classification on customs examination — for instance, where a magnetron is imported as part of a system rather than as a discrete component — triggers retrospective compliance and potential detention. Verify the import declaration accurately reflects a standalone magnetron component against the customs tariff before relying on the absence of compliance.
