Acrylamide with MEHQ Inhibitor
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.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If inhibitor levels suggest primary phenol-function product
High phenol content would classify under oxygen-function amines/phenols (2914) later in order.
If when marketed specifically as flotation reagent with surfactants
Specific end-use chemical preparations take precedence over base compound classification.

Import Tips & Compliance
• 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
