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.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If pebbled or crushed for ballast use
Chapter note prioritizes heading 2517 for pebbled/ crushed pebbles, gravel, etc., overriding 2530 even for celestite.
If chemically purified to >95% SrSO4
Purified strontium sulfate becomes a synthetic chemical product under Chapter 28, excluding natural mineral forms.
If Calcined or fluxed celestite loses NES mineral status under 2530.

Import Tips & Compliance
• Verify strontium sulfate content >90% via assay certificate to confirm celestite classification; obtain mining origin documentation; avoid misclassification as processed strontium chemicals in Chapter 28

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.
Natural Celestite Crystals
Transparent celestite crystal clusters from Sidoarjo, Indonesia mines, prized for strontium content and collector value. HTS 2530.90.8010 covers these unworked mineral specimens. Used in metallurgical flux and pyrotechnics.
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.
