Rough Quartz Crystals
Natural quartz crystals mined from deposits, typically in irregular shapes without further processing beyond extraction. Classified under HTS 2506.10.00 as quartz other than natural sands, distinct from processed or crushed forms. Used primarily for industrial grinding into powders or as raw material for silicon production.

This product may fall under a more specific subheading:
Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If in granular or powdered form resembling natural sands
Natural sands of quartz fall under 2505, while solid quartz blocks or crystals are 2506
If roughly trimmed into pebbles or granules
Pebble and gravel classifications shift to 2517 for aggregate uses
If further processed into articles or shapes
Worked quartz articles like plates move to Chapter 68

Import Tips & Compliance
• Verify origin certificates to distinguish from natural sands under 2505; ensure no sawing or shaping exceeds 'merely cut' to avoid reclassification
• Common pitfall: mislabeling as silica sand leading to incorrect duties

Quartzite Slab Blocks
Quartzite rock roughly sawn into rectangular slabs or blocks for further processing. Falls under HTS 2506.10.00 as quartzite merely cut by sawing, not further worked into finished dimensions. Commonly used in construction for crushing into aggregate.
High-Purity Quartz Chunks
Selected quartz chunks with over 99.9% SiO2 purity, minimally processed for electronics industry feedstock. HTS 2506.10.00 covers this as unworked quartz other than sands. Essential raw material for semiconductor-grade silicon.
Sawn Quartzite Blocks
Quartzite blocks cut by sawing into rectangular shapes, suitable for monumental or architectural use. Classified in 2506.10.00 as merely cut, not further dressed or polished. Used in stone fabrication industries.
Natural Quartz Pebbles
Rounded quartz pebbles collected from riverbeds, not artificially crushed, used in decorative landscaping. HTS 2506.10.00 applies as quartz other than sands, provided not sized as gravel. Excludes processed aggregates.
Quartz Ore Lumps
Lumpy quartz ore from mining operations, containing high silica for glassmaking feedstock. Falls under 2506.10.00 as unprocessed quartz excluding sands. Primary input for float glass production.
Rectangular Quartzite Slabs
Quartzite cut into rectangular slabs by simple sawing, for subsequent crushing or slab processing. HTS 2506.10.00 specifically includes such merely cut forms. Used in countertops after further fabrication.
