Import Tips
• Include technical specs confirming mechanical needling (not thermal/chemical) and exact areal weight to prevent reclassification
• Label as 'not for apparel/textiles' to avoid scrutiny under Chapter 59 if perceived as textile substitute
• Check for any pre-annealing processes per Chapter Note (a); such glass remains unworked if before annealing
