Melamine has been subject to antidumping duty proceedings targeting specific country origins. Importers should check the current scope of any active antidumping orders with CBP or the International Trade Administration before importing, as additional duties and bonding requirements may apply.
Industrial-grade melamine is typically traded at 99.8% minimum purity. Moisture content, ash content, and particle size affect downstream resin performance. Buyers should specify these parameters in purchase contracts and request certificates of analysis, as off-spec material can cause processing problems in laminate and adhesive manufacturing.
