Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If leucite content dominates over 50%
Predominantly leucite ore shifts to specific 2528.10 classification.
If unexpanded vermiculite impurities
Vermiculite-contaminated feldspar may classify under 2530 per chapter note.

Import Tips & Compliance
• Conduct XRF analysis to quantify K-feldspar vs leucite ratios for accurate heading declaration
• Declare volcanic ash content if present, as it may trigger agricultural quarantine inspections
• Use magnetic separation certificates to confirm low iron for premium ceramic applications

Potassium Feldspar Powder
Potassium feldspar, also known as orthoclase, is a common rock-forming mineral mined and ground into powder for use as a flux in ceramic glazes and porcelain production. This product falls under HTS 2529.10.00.00 as it is natural feldspar that has been crushed and milled but remains chemically unchanged, classified specifically as feldspar in Chapter 25.
Sodium Feldspar Lumps
Sodium feldspar (albite) in lump form is extracted from pegmatite deposits and used primarily in glass manufacturing as a source of alumina and silica. Classified under HTS 2529.10.00.00 as raw feldspar, it has undergone minimal processing like crushing to lump size without chemical alteration.
Ceramic Grade Feldspar
High-quality feldspar graded for ceramics, with low iron content to prevent discoloration in tiles and sanitaryware. It is natural feldspar plug for sanitaryware glazes under HTS 2529.10.00.00, as it remains an unprocessed aluminosilicate mineral.
Glass Grade Feldspar Powder
Feldspar finely milled to uniform particle size for soda-lime glass production, providing network formers without further refinement. Falls under HTS 2529.10.00.00 as it's crude feldspar, not chemically synthesized.
Nepheline Syenite Feldspar Blend
Blended feldspar from nepheline syenite deposits, offering low iron and high alkali for paint extenders and ceramics. HTS 2529.10.00.00 applies to the dominant feldspar component in this natural mineral product.
