Summary
HS code 2922.21 covers amino-naphthols and other amino-phenols, other than those containing more than one kind of oxygen function, their ethers and esters; salts thereof, aminohydroxynaphthalenesulphonic acids and their salts. It sits in heading 29.22 (oxygen-function amino-compounds) in chapter 29 (organic chemicals). Other goods of heading 29.22 are classified under 2922.11 (amino-alcohols, other than those containing more than one kind of oxygen function, their ethers and esters; salts thereof, monoethanolamine and its salts), 2922.12 (amino-alcohols, other than those containing more than one kind of oxygen function, their ethers and esters; salts thereof, diethanolamine and its salts), 2922.14 (amino-alcohols, other than those containing more than one kind of oxygen function, their ethers and esters; salts thereof, dextropropoxyphene (INN) and its salts), 2922.15 (amino-alcohols, other than those containing more than one kind of oxygen function, their ethers and esters; salts thereof, triethanolamine) or 13 others. National tariff lines under 2922.21 are live on border.bot for the United States (4 lines, also used by 1 other country).
What this code covers

How it is structured
2922.21 is a six-digit subheading. Its first two digits, 29, are the chapter; the first four, 2922, are heading 29.22; the last two, 21, identify the subheading within the heading.
Countries add their own digits after these six for their national tariff lines.
