About chapter 25
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.

Codes and descriptions follow the WCO six-digit Harmonized System nomenclature. National tariff schedules extend these to 8–13 digits and set the actual duty rate, so confirm the full code for your destination country with your customs broker before filing. To copy a code, hover a row and use the copy button; every code has 2501-style dot notation ready for your commercial invoice.
Chapter 25 FAQ
What does HS code chapter 25 cover?
Chapter 25 of the Harmonized System covers: salt; sulphur; earths, stone; plastering materials, lime and cement. It belongs to section V (Mineral Products) and contains 29 four-digit headings, 2501–2530.
How many HS codes are in chapter 25?
Chapter 25 contains 29 four-digit headings and 67 six-digit subheadings. Countries subdivide these further (8–13 digits) in their national tariff schedules, so the full national count is larger.
Is HS code 2501 the same in every country?
Yes. The six-digit level of every code in this chapter is harmonised by the World Customs Organization and identical in all member countries. Digits beyond the sixth (for example the US 10-digit HTS or the EU 8-digit CN) are national and set the actual duty rate.
How do I choose the right code within chapter 25?
Work from the four-digit heading down: pick the heading that best matches your product, then the six-digit subheading that matches its material, form or processing. If two codes seem to fit, customs rules (the General Rules of Interpretation) decide, and when in doubt, confirm with your customs broker before filing.
