Import Tips
• Label products clearly as 'glaziers' putty' to distinguish from general caulks during customs review
• Provide manufacturer specs confirming rubber base to avoid reclassification to bituminous mastics (excluded by Chapter notes)
• Check state regulations for VOC limits; non-compliant imports may face detention
