Fused magnesia (natural)

Fused magnesia of natural origin

NO PGA · STANDARD CUSTOMS PROCEDURE

HSN 2519 90 10 (fused magnesia, natural) 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. Sibling tariff lines within Chapter 25 — covering dead-burned (sintered) magnesia and other magnesium oxide — may attract distinct classification treatment, and the intended use of the material can affect how customs assesses the correct line.

No partner government agency notification covers this tariff line.

A word of counsel

Fused magnesia of synthetic or non-natural origin, dead-burned (sintered) magnesia, and chemically pure magnesium oxide are each classified under separate tariff lines within Chapter 25; the natural-origin qualifier at this line is a classification load-bearing detail. A customs examination that re-characterises the grade or origin of the material can trigger re-classification, with retrospective duty recovery and detention pending resolution. Importers should retain technical datasheets, production certificates, and supplier declarations that confirm natural origin and the fusion process.

Frequently asked

Does HSN 2519 90 10 require any pre-import registration?

A valid Importer-Exporter Code is required for any commercial import; no product-specific registration applies to this tariff line.

What changes if the magnesia is dead-burned or sintered rather than fused?

Dead-burned (sintered) magnesia is classified under a separate tariff line within Chapter 25 and may carry different duty rates and compliance considerations, making the process distinction — fusion versus sintering — a material classification variable.
