2506.20 Quartzite; whether or not roughly trimmed or merely cut, by sawing or otherwise, into blocks or slabs of a rectangular (including square) shape
A full HS code. These six digits are what goes on a customs declaration, and they mean the same thing in every country that uses the Harmonized System.
Section V, Mineral Products — salt, sulphur, earths, stone, ores, mineral fuels and mineral oils.
- 25 Chapter Salt; sulphur; earths, stone; plastering materials, lime and cement
- 06 Heading Quartz; (other than natural sands), quartzite, whether or not roughly trimmed or merely cut, by sawing or otherwise, into blocks or slabs of a rectangular (including square) shape
- 20 Subheading Quartzite; whether or not roughly trimmed or merely cut, by sawing or otherwise, into blocks or slabs of a rectangular (including square) shape
Chapter 25 covers salt, sulphur, earths and stone, plastering materials, lime and cement: bulk mineral commodities in their natural or minimally processed state, used mostly as construction and industrial inputs. Classification tip: These are typically high-volume, low-value-per-tonne bulk commodities, so freight cost (not duty) usually dominates the landed-cost calculation: confirm the shipping mode and Incoterm before quoting a price.

The wording above is the Harmonized System nomenclature as published by the World Customs Organization, HS 2022 edition. It is a classification reference, not a tariff: it carries no duty rates, and it stops at six digits — the importing country adds its own beyond that.
Classification is decided by the General Rules of Interpretation and the section and chapter notes, and it is the importing country’s customs authority that makes it binding.

2506.20 covers quartzite; whether or not roughly trimmed or merely cut, by sawing or otherwise, into blocks or slabs of a rectangular (including square) shape. It sits under heading 25.06 (quartz; (other than natural sands), quartzite, whether or not roughly trimmed or merely cut, by sawing or otherwise, into blocks or slabs of a rectangular (including square) shape) in chapter 25, Section V of the Harmonized System.
It is the international part of it. Six digits are the same in every country that applies the Harmonized System; the importing country then extends them to eight or ten for its own tariff and statistics. Declare 2506.20 plus whatever national digits the destination’s tariff schedule adds to it.
The General Rules of Interpretation, read together with the notes to Section V and to chapter 25. A description that reads right is not enough on its own — the notes routinely pull goods out of the chapter they obviously belong to and put them somewhere else. Where duty or licensing turns on the answer, ask the importing country’s customs authority for a binding ruling.
A wrong or missing code is one of the common reasons customs holds a container, and a hold shows up as a milestone that stops moving. Watch for it in the container tracking app, on the air waybill in the air cargo tracker, or through the tracking API.
