Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If blended with other monomers as a polymerizable mixture
Prepared chemical mixtures for specific polymerization processes fall under 3824, not individual pure esters.
If supplied as low-molecular weight acrylic copolymer solution
Unsaturated acrylic polymers, even at oligomer stage, classify in Chapter 39 polymers.
If containing additional saturated acid functions
Saturated acyclic monocarboxylic acid esters go to 2915; unsaturated acrylic function prevails here per Chapter notes.

Import Tips & Compliance
• Declare exact isomer (n-butyl vs iso-butyl) with GC-MS analysis to prevent reclassification disputes
• Include hydroquinone stabilizer concentration; levels affect stability and may require special handling declarations
• Ensure DOT/UN shipping papers specify PG II flammable liquid classification
