In lumps
Quartz in lumps (natural, unfused)
HSN 2506 10 10 (Quartz in lumps) is governed by the Directorate General of Foreign Trade (DGFT) under the ITC (HS) import policy for Chapter 25 mineral imports, with no sector-specific Partner Government Agency licensing requirement at the bill-of-entry stage. Correct classification is the operative customs obligation: CBIC Circular 03/2012-Cus dated 01-02-2012 confirms that synthetically produced fused silica is excluded from sub-heading 2506 and must be declared under an alternative heading.
- Country of origin certificate from exporter
- Commercial invoice from supplier
- 1Verify that the quartz being imported is naturally occurring and not synthetically produced fused silica before declaring sub-heading 2506 10 10. Synthetically produced fused silica is ineligible for classification under sub-heading 2506 and will be reclassified by the proper officer, attracting differential duty recovery and potential mis-declaration proceedings.CBIC Circular 03/2012-Cus dated 01-02-2012, Para 4.1
- 2File the bill of entry under the free-import regime applicable to natural quartz in lumps. Retain mineralogical or laboratory test documentation from the exporter confirming natural origin to support classification at examination; customs officers referencing Circular 03/2012-Cus will query the origin-type of any quartz-family import.CBIC Circular 03/2012-Cus dated 01-02-2012, Para 4.1
The single most consequential error on this tariff line is presenting synthetically produced fused silica under HSN 2506 10 10 — whether by misunderstanding the product or by supplier misdescription. CBIC Circular 03/2012-Cus is explicit that fused silica produced by synthesis falls outside sub-heading 2506 entirely; reclassification at the port triggers retroactive duty demand, interest, and potential mis-declaration penalty, none of which are curable by post-clearance amendment once the goods are out-of-charge.
