Import Tips & Compliance
• Specify panel dimensions and locking mechanism in commercial invoice to distinguish from welded grating
• Include load class certification (e.g
• AS1657) for structural compliance verification
• Avoid common pitfall of declaring as 'mesh' which could shift to Chapter 73 wire products
