Import Tips

Request silica content certification (min 60% for glass wool note applicability, though woven is filament-based)

Avoid common error of declaring as 'mat' which falls under 7019.90.5030; specify plain weave

Use HTS lookup tools for origin-specific duties, especially from Asia-Pacific producers
