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
