Import Tips
• Label with exact mineral composition (e.g
• % rock wool) and temperature rating for accurate HTS verification
• Check for country-of-origin marking; common issue with blended fibers from multiple sources
• Bundle with foil facing? Enter facing separately if it's a distinct plastic/metal layer under other chapters
