Natural arsenic sulphides (such as orpiment)

Natural arsenic sulphides (orpiment and related minerals)

NO PGA · STANDARD CUSTOMS PROCEDURE

HSN 2530 90 20 (Natural arsenic sulphides, such as orpiment) 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 mineral substances under Chapter 25, or arsenic compounds processed beyond their natural state and classified under Chapter 28, may carry distinct compliance obligations.

No partner government agency notification covers this tariff line.

A word of counsel

Natural arsenic sulphides occupy a narrow residual tariff line; the principal importer risk is misclassification — either upward into Chapter 28 (inorganic chemicals, including refined arsenic compounds) or sideways into other Chapter 25 mineral lines that do carry regulatory overlay. Customs re-classification on examination triggers retrospective compliance, including detention pending the relevant clearance. Confirm the product's mineralogical form, purity grade, and intended use against the customs tariff before treating the absence of compliance as settled.

Frequently asked

Does HSN 2530 90 20 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 arsenic sulphide has been processed or refined beyond its natural mineral state?

Processed or refined arsenic compounds are typically classified under Chapter 28 (inorganic chemicals), which carries its own compliance and may attract Partner Government Agency scrutiny not applicable to the natural mineral form.
