Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If in cosmetic formulations
Beauty preparations containing microbeads classify in Chapter 33.
If for laboratory chromatographic use
Lab apparatus parts supersede primary polymer classification.
If petroleum sulfonate coated
Surface-modified polymers may shift to polysulfone subheadings.

Import Tips & Compliance
• Particle size distribution and crosslinking density reports essential for primary form proof
• Prevent classification as cosmetic ingredient (Chapter 33) by shipping unpackaged
• Avoid retail packaging; bulk primary forms maintain Chapter 39 status
