Melamine-Formaldehyde Resin
Melamine-formaldehyde resin is a thermosetting amino-resin produced by the reaction of melamine with formaldehyde, containing over 95% by weight of these monomer units. It is supplied in primary form as granules or powder for molding into tableware and laminates. Classified under HTS 3909.39.00.00 as 'Other' amino-resins not specifically named elsewhere in the series.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If primarily urea-formaldehyde composition
Urea-formaldehyde polymers with predominant urea monomer units fall under the specific subheading 3909.10 for other urea-formaldehyde resins.
If chemically modified or blended below 95% purity
Per subheading notes, polymers not meeting 95% monomer threshold or chemically modified are classified under 'Other' polyurethane or polyamide subheadings if predominant monomer shifts.
If imported as prepared binder or mix with additives
If supplied as a formulated adhesive or binder exceeding simple primary form, it shifts to Chapter 38 for prepared chemical products.

Import Tips & Compliance
• Verify monomer content exceeds 95% melamine/formaldehyde units via lab testing to confirm classification; provide technical data sheets on production process; watch for misclassification as urea-formaldehyde under 3909.10
