HS Code for Quartz

Quartz is one of the most abundant minerals in the Earth's continental crust and is classified under Chapter 25 of the Harmonized System, which covers salt, sulfur, earths and stone, plastering materials, lime, and cement. Heading 2506 is designated for quartz (other than natural sands) and quartzite, whether or not roughly trimmed or merely cut, by sawing or otherwise, into blocks or slabs of a rectangular shape. Subheading 2506.10 specifically addresses quartz in its various natural forms, excluding those that have been processed into precious stones or industrial sands. The classification depends on the physical state of the mineral and the level of processing it has undergone. Natural quartz classified here is typically in the form of crude stones, fragments, or crystals that have not been worked for jewelry or specific industrial applications like glassmaking sands. The distinction between quartz and quartzite is also vital, as quartzite is classified under 2506.20. For the purposes of 2506.10, the material must be primarily composed of silicon dioxide in its crystalline form and must not have been subjected to any process beyond simple cleaning, crushing, or rough shaping.

Products Included

• Natural quartz crystals
• Crushed quartz for industrial use
• Raw rock crystal
• Smoky quartz in crude form
• Rose quartz (non-gemstone quality)
• Quartz fragments and spalls

Common Misclassification

The most common misclassification occurs with natural sands, which are classified under HS code 2505.10 (silica sands and quartz sands). If the quartz has been naturally or mechanically reduced to a grain size consistent with sand, it must be moved to Chapter 2505. Furthermore, high-quality quartz crystals intended for use as gemstones (like amethyst or citrine) are classified under HS code 7103.10 as semi-precious stones. Finally, synthetic quartz is classified under HS code 7104.10.

FAQ

What is the HS code for Quartz?

The HS code for natural quartz, other than natural sands, is 2506.10.

Does this code include quartz used for kitchen countertops?

No, engineered quartz surfaces or slabs used for countertops are typically classified under HS code 6810.99 as articles of artificial stone, as they contain resin binders.
