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
