Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If for non-silica high-temp glass fabrics
Other colored roving fabrics without >93% silica spec fall into adjacent 'other' categories.
If slag wool or rock wool composition
Slag or rock-based mineral wools don't qualify as fused silica products.
If in sheet/carpet form for other uses
Glass fiber sheets and profiles shift to 7010 if not qualifying as woven fabrics.

Import Tips & Compliance
• Provide thermal performance data (e.g
• continuous use temp >1000°C) supporting silica purity claims
• Separate from ceramic fiber products to avoid overlap with 6806 classifications
• Check for REACH compliance if destined for EU re-export, given high-silica composition
