About heading 2822
Cobalt oxides and hydroxides; commercial cobalt oxides
Heading 2822 covers cobalt oxides and cobalt hydroxides, including commercial cobalt oxides sold as powders and pigments. It has two declarable lines: one for cobalt(II, III) oxide (cobalt tetroxide) and one residual line for all other cobalt oxides and hydroxides. Both lines carry the same general (MFN) rate of 0.1%.
