Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If cut/polished as semiprecious stones
Chapter exclusion sends worked precious/semiprecious stones to Chapter 71.
If sized for granular road base
Pebbles/granules for construction classified preferentially in heading 2517.
If dissolved strontium extracted
Chemical strontium compounds from processing excluded from Chapter 25 minerals.

Import Tips & Compliance
• Provide XRF analysis confirming SrSO4 composition; separate crystals from worked specimens (gem/polished); declare collector vs industrial intent accurately

Raw Celestite Ore
Natural strontium sulfate mineral ore extracted from sedimentary deposits, primarily composed of celestite (SrSO4) with minor impurities. Classified under HTS 2530.90.8010 as celestite, a mineral substance not elsewhere specified in Chapter 25. Supplied in bulk for processing into strontium compounds.
Celestite Mineral Lumps
Hand-sorted celestite lumps (5-50mm) from Mexican deposits, containing 95-98% SrSO4. Falls under HTS 2530.90.8010 as unprocessed celestite mineral for strontium extraction. Used in fireworks and glass production.
Celestite Flotation Concentrate
Wet-processed celestite concentrate from froth flotation (97% SrSO4), dried but uncalcined. Still classified as crude celestite under HTS 2530.90.8010 since beneficiation doesn't constitute chemical change. Feedstock for strontium carbonate production.
Mexican Blue Celestite Ore
Characteristic blue celestite ore from Coahuila, Mexico deposits (96% SrSO4), exported in 50kg bags. HTS 2530.90.8010 specifically identifies celestite mineral from primary global source. Supplies 70% of world strontium demand.
Strontianite-Celestite Mixed Ore
Mixed strontium minerals containing both celestite (SrSO4) and strontianite (SrCO3) from vein deposits. Principal component celestite justifies HTS 2530.90.8010 classification per essential character. Used interchangeably in strontium processing.
