HS Code 2507.00 – Kaolin and other kaolinic clays; whether or not calcined
HS code 2507.00 is the 6-digit subheading for kaolin and other kaolinic clays, whether or not calcined. It is used for kaolin clay, calcined kaolin, paper coating kaolin, ceramic grade kaolin and filler kaolin.
What HS 2507.00 covers
Kaolin, also known as china clay, and other kaolinic clays, whether or not calcined, fall under this HS code. This versatile industrial mineral is a cornerstone for numerous manufacturing sectors due to its whiteness, softness, chemical inertness, and excellent rheological properties. It is indispensable in the paper industry for coating and filling, in ceramics for porcelain and sanitaryware, and as a filler in paints, rubber, and plastics. Major importers are typically manufacturing economies like China, the USA, and Germany, which have large paper, ceramic, and chemical industries. Exporters are countries with abundant kaolin deposits and processing infrastructure, such as the USA, Brazil, and the UK. Trade involves various grades, with calcined kaolin offering enhanced brightness and opacity, commanding higher value.

How these figures are built
109 countries reported 2025 trade to UN Comtrade in HS 2022, and their own totals are used. Countries that did not report are estimated from what other countries recorded trading with them. Those estimates miss trade with other non-reporting countries, so they can be low, and a non-reporting country can rank higher than shown or be missing from the list. World totals add both and leave out trade between two non-reporting countries. Figures are in current US dollars; reported imports are mostly valued CIF and exports FOB, and exports include re-exports. The UN Comtrade links show the underlying records; they can also list a few reporters left out here (regional groups and older HS editions).
