Natural magnesium carbonate (magnesite)
Natural magnesium carbonate (magnesite), crude or unprocessed
HSN 2519 10 00 (Natural magnesium carbonate — magnesite) 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 magnesium compounds within Chapter 25 — including fused magnesia and dead-burned (sintered) magnesia — are classified under sibling tariff lines that may carry distinct compliance.
The absence of compliance at this tariff line applies specifically to natural, unprocessed magnesite; further-processed forms such as fused magnesia, dead-burned magnesia, and pure magnesium oxide are separately classified within Chapter 25 and may attract their own obligations. Re-classification by customs on examination — for instance, where the product has been calcined or beneficiated — triggers retrospective compliance and potential detention. Verify the processing state and chemical specification of the imported material against the customs tariff before relying on the absence of compliance at this line.
