Import Tips

Verify exact dimensions with calipers before shipment to confirm compliance with 91cm width, 184cm length, and 8cm depth thresholds

Provide detailed coil count and steel specifications in commercial invoices to avoid reclassification as parts

Ensure no outer ticking or fabric is attached, as covered units shift to 9404.29.1000; inspect for minimal edge support only
