Carboxylic acids with additional oxygen function and their anhydrides, halides, peroxides and peroxyacids; their halogenated, sulfonated, nitrated or nitrosated derivatives
Analysis
Heading 2918 of the Harmonized Tariff Schedule covers carboxylic acids with additional oxygen function and their anhydrides, halides, peroxides and peroxyacids; their halogenated, sulfonated, nitrated or nitrosated derivatives. It divides into 16 six-digit subheadings and 56 eight-digit tariff lines, with 62 ten-digit statistical suffixes below them.
The spread of 6.5 percentage points between the cheapest and dearest lines makes misclassification expensive here. The highest rate, 6.5%, applies to 2918.15.10 (salts and esters of citric acid: sodium citrate) and 2918.18.00 (chlorobenzilate (ISO)).
11 of its 56 lines with a percentage rate are duty-free at the general rate (20%) and 45 are dutiable, from duty-free up to 6.5%. The median line pays 6%.
The largest subheadings are 2918.29 (other, 10 lines), 2918.99 (other, 10 lines), 2918.19 (other, 7 lines) and 2918.30 (carboxylic acids with aldehyde or ketone function…, 6 lines).
Its median rate of 6% sits at the 66th percentile of the headings in chapter 29.
