About heading 2925

Carboxyimide-function compounds (including saccharin and its salts) and imine-function compounds

Heading 2925 covers carboxyimide-function compounds, including saccharin and its salts, and imine-function compounds. It splits first by function: imides and their derivatives in 2925.11 through 2925.19, and imines and their derivatives in 2925.21 through 2925.29. Within each group the lines move from specific named compounds to aromatic and then other residual lines, with mixed duty rates.
