Import Tips
• Verify stainless steel grade (e.g
• 304 or 316) meets ASTM standards for corrosion resistance in structural applications
• Include mill test certificates (MTC) to confirm material composition and avoid reclassification as non-structural parts
• Ensure frames are not pre-glazed or assembled with glass to prevent misclassification under Chapter 76 or 94
