Import Tips & Compliance
• Verify that the glass sheets are rectangular and not cut to shape, as cutting to shape may still be acceptable per chapter note 2(b)
• Declare the exact area and thickness to confirm classification
• Check if the glass is considered 'worked' due to any annealing or surface treatment
