HS Code 25: Salt; sulphur; earths and stone; plastering materials, lime and cement

Q: Is HS code 25 the same in every country?

Yes — HS code 25 is part of the WCO Harmonized System and is the same in every WCO member country at the 6-digit level. Beyond 6 digits, each country extends the code under its own system (e.g. HTSUS in the US, CN/TARIC in the EU, HSK in Korea, CCCHS in China) for national tariff rates and trade statistics. To see how a specific country classifies this code, select a country.

Q: Which WCO edition does HS code 25 belong to, and has it been reclassified?

The Harmonized System is maintained by the World Customs Organization (WCO) and revised approximately every five years. The current edition is HS 2022, which replaced HS 2017 on 1 January 2022. Codes are added, merged, or split between editions to reflect new products and trade patterns, so a code valid in one edition may not exist or may mean something different in another.

Q: How do I find the correct country-specific version of HS code 25?

Beyond the international 6-digit level, each country adds its own digits — the US extends to 10 digits (HTSUS), the EU to 8 or 10 (CN/TARIC), China to 13 (CCCHS), Korea to 10 (HSK), Japan to 9, and so on. To find the full code used by a specific country, select a country in TradeInt's HS Code Tool and search for 25.

What is HS Code 25

HS Code 25 covers Salt; sulphur; earths and stone; plastering materials, lime and cement. It is one of the 96 chapters of the WCO Harmonized System, sitting in Section V (Mineral products). The two digits "25" are the chapter level — every 4-digit heading and 6-digit subheading starting with "25" belongs here.
