Crosslinked Acrylic Microbeads
Highly crosslinked polymethyl methacrylate microbeads used in cosmetics and chromatography. Despite the crosslinking, the polymer remains an acrylic polymer in primary form, and the chemical modification does not create a specific subheading. It is classified under the 'Other' tariff item as it is not specifically named elsewhere.

More Specific Codes
This product may fall under a more specific subheading:
Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If the methyl methacrylate monomer contributes 95% or more by weight and the polymer is not crosslinked
Subheading note 1(a)(1) applies to the specific PMMA subheading when the monomer threshold is met.
If the microbeads are incorporated into a finished cosmetic preparation for retail sale
Finished cosmetic products are classified in Chapter 33, not as primary polymers.
If the microbeads are presented as diagnostic or laboratory reagents on a backing
Chapter 39 note 2(k) excludes such goods, directing them to Chapter 38.

The Tariff Assistant works through the GRI rules on your specific product to reach the right tariff item — and can price the duty on it in the same conversation.
Import Tips & Compliance
• Confirm the microbeads are in primary forms (e.g
• powder) and not mixed into cosmetic preparations, which would shift classification to Chapter 33
• Have documentation on the degree of crosslinking and monomer composition to support classification
• Verify whether the microbeads meet the definition of 'plastics' under Chapter 39 note 1, as they must be capable of being formed
Related Products under Tariff item 3906.90.00
Acrylic Copolymer Beads for Coatings
Solid beads of acrylic copolymers designed for water-based paints and industrial coatings, meeting the 95% acrylic monomer threshold. They are classified under this tariff item as acrylic polymers in primary forms.
Acrylic Copolymer Beads for Paint
Solid acrylic copolymer beads used as the base resin in water-based paints and coatings, supplied in primary form. The copolymer's comonomer units contribute 95% or more by weight, qualifying it as an acrylic polymer under heading 39.06. It is not specifically named in another subheading, so it falls under the 'Other' tariff item.
Acrylic Elastomeric Polymer Resin
An acrylic elastomeric polymer resin in primary form, exhibiting rubber-like elasticity and recovery. It is classified under this tariff item as an acrylic polymer in primary forms, not elsewhere specified.
Acrylic Impact Modifier Pellets MBAM
Methyl methacrylate-butadiene-acrylate-methyl methacrylate (MBAM) copolymer pellets used to toughen PVC. The acrylic monomers (methyl methacrylate and acrylate) predominate by weight over the butadiene, so the polymer is classified as an acrylic polymer. It is not a named copolymer in subheading 3906.10, so it falls under the 'Other' tariff item.
Acrylic Pressure-Sensitive Adhesive Polymer Emulsion Solids
Dried polymer solids recovered from acrylic emulsion for pressure-sensitive adhesives, supplied as spray-dried powder, with over 95% acrylic polymer content. It falls under this tariff item as an acrylic polymer in primary forms.
Acrylonitrile Elastomeric Copolymer
An elastomeric copolymer of acrylonitrile and butyl acrylate in bale form, with 95% total acrylic content. It falls under this tariff item as an acrylic polymer in primary forms, not specifically named elsewhere.
