Last updated: April 2026 data

Amino-resins not captured by the melamine or urea/thiourea headings — such as benzoguanamine-formaldehyde or glycoluril-based resins — are classified here as a residual NES category. These specialty resins serve niche roles in coatings crosslinkers, textile finishing agents, and paper wet-strength applications where standard MF or UF chemistry is insufficient. Because the NES designation requires affirmative exclusion from the named amino-resin types, importers should retain detailed polymer characterization data to defend classification during CBP review.

Frequently Asked Questions

What types of resins are typically classified as NES amino-resins?

Benzoguanamine-formaldehyde, acetoguanamine-formaldehyde, and glycoluril-based resins are common examples. These are used as crosslinkers in high-performance coatings and as specialty textile finishes where melamine or urea resins do not meet performance requirements.

What documentation is recommended to support an NES amino-resin classification?

A technical data sheet identifying the specific amino compound (not melamine, urea, or thiourea) and the formaldehyde condensation chemistry, along with a manufacturer's certificate of analysis, provides the clearest basis for the NES classification. Consulting a licensed customs broker is advisable given the residual nature of this category.
