Import Tips
• Test and certify breathability/permeability if for hygiene; customs may require proof impregnation isn't full plastic coating
• Avoid bulk packaging pitfalls by declaring as 'coverstock' not finished diapers to stay in 5603 vs Chapter 96
• Origin rules strict for man-made fibers; provide polymerization certificates for preferential tariffs
