About heading 2530

Mineral substances not elsewhere specified or included

Heading 2530 covers mineral substances that are not specified or included in any other heading, so it works as a residual heading for non-metallic minerals. It is split into three groups: vermiculite, perlite and chlorites (unexpanded); natural magnesium sulfates, meaning kieserite and epsom salts; and a residual other group for cryolite, chiolite, micaceous iron oxides, celestite and earth colors. Most lines in the heading carry a free general (MFN) rate, with natural micaceous iron oxides as the exception.
