Import Tips & Compliance
• Test at multiple points for uniform 185 gsm; exceeding triggers 7019.66.50 reclassification and higher scrutiny
• Provide electrical properties data for end-use validation in electronics applications
• Declare as 'mechanically bonded' specifically; vague descriptions cause processing delays
