Acrylamide with MEHQ Inhibitor from China

Acrylamide containing 30-50 ppm 4-methoxyphenol (MEHQ) as polymerization inhibitor for extended shelf life. Remains under HTS 2924.19.11.10 per Chapter 29 note (f) as stabilizer doesn't render product specific-use beyond general chemical applications.

Import Tips

Quantify inhibitor precisely on commercial invoice (typically 20-60 ppm) to validate stabilizer exception

Confirm MEHQ addition solely prevents premature polymerization during transport per Chapter notes

Monitor total impurities; >2% may risk reclassification as technical mixtures
