What you need to know to export Chapter 25
Chapter 25 covers 31 headings grouped into three types: raw minerals (salt, sulphur, earths, stone), processed construction materials (cement, lime, gypsum) and specialty products (asbestos, mica, feldspar). Each heading has its own tariff and import rules in destination markets.
Questions about exporting Chapter 25
What is the difference between Chapter 25 and Chapter 26 minerals?
Chapter 25 covers non-metal minerals used in construction and industry (salt, stone, cement, lime). Chapter 26 covers metal-bearing minerals and ores (iron, copper, zinc). The two chapters have different tariffs and export rules. Confirm the correct classification with the buyer before trading.
