Leucite Ore Concentrate from Japan

Concentrated leucite (potassium aluminosilicate) ore extracted from volcanic deposits, used in specialty ceramics and as a potassium source in fertilizers. Classified under HTS 2529.30.00 as crude or beneficiated leucite, not chemically altered. Its high potash content makes it valuable for glass batch formulations.

Import Tips

Provide XRF chemical analysis confirming leucite composition (>50% KAlSi2O6) to prevent confusion with nepheline

Declare radioactivity levels if from volcanic sources; comply with USGS import guidelines for strategic minerals

Avoid packaging that suggests processing; use 'crude ore' labeling to maintain 2529 classification
