Summary
HS code 2918.22 covers carboxylic acids with phenol function but without other oxygen function, their anhydrides, halides, peroxides, peroxyacids and their derivatives, O-Acetylsalicylic acid, its salts and esters. It sits in heading 29.18 (carboxylic acids with additional oxygen function and their anhydrides, halides, peroxides and peroxyacids; their halogenated, sulphonated, nitrated or nitrosated derivatives) in chapter 29 (organic chemicals). Other goods of heading 29.18 are classified under 2918.11 (carboxylic acids with alcohol function but without other oxygen function, their anhydrides, halides, peroxides, peroxyacids and their derivatives, lactic acid, its salts and esters), 2918.12 (carboxylic acids with alcohol function but without other oxygen function, their anhydrides, halides, peroxides, peroxyacids and their derivatives, tartaric acid), 2918.13 (carboxylic acids with alcohol function but without other oxygen function, their anhydrides, halides, peroxides, peroxyacids and their derivatives, salts and esters of tartaric acid), 2918.14 (carboxylic acids with alcohol function but without other oxygen function, their anhydrides, halides, peroxides, peroxyacids and their derivatives, citric acid) or 11 others. National tariff lines under 2918.22 are live on border.bot for the United States (2 lines, also used by 1 other country).
What this code covers
HS code 2918.22 covers carboxylic acids with phenol function but without other oxygen function, their anhydrides, halides, peroxides, peroxyacids and their derivatives, O-Acetylsalicylic acid, its salts and esters.
The legal text of the subheading is “Carboxylic acids with phenol function but without other oxygen function, their anhydrides, halides, peroxides, peroxyacids and their derivatives: O-Acetylsalicylic acid, its salts and esters”, read under “Carboxylic acids with phenol function but without other oxygen function, their anhydrides, halides, peroxides, peroxyacids and their derivatives”, in HS2022.
What it doesn’t cover
Other goods of heading 29.18 are classified under 2918.11 (carboxylic acids with alcohol function but without other oxygen function, their anhydrides, halides, peroxides, peroxyacids and their derivatives, lactic acid, its salts and esters), 2918.12 (carboxylic acids with alcohol function but without other oxygen function, their anhydrides, halides, peroxides, peroxyacids and their derivatives, tartaric acid), 2918.13 (carboxylic acids with alcohol function but without other oxygen function, their anhydrides, halides, peroxides, peroxyacids and their derivatives, salts and esters of tartaric acid), 2918.14 (carboxylic acids with alcohol function but without other oxygen function, their anhydrides, halides, peroxides, peroxyacids and their derivatives, citric acid) or 11 others.

How it is structured
2918.22 is a six-digit subheading. Its first two digits, 29, are the chapter; the first four, 2918, are heading 29.18; the last two, 22, identify the subheading within the heading.
Countries add their own digits after these six for their national tariff lines.
