Import Tips

• Label with exact material compatibility (e.g

• silicon carbide resistant) and pressure ratings for customs validation

• Bundle with saw documentation to prove integral part status versus replacement wear item

• Avoid pitfall of classifying as 8202 saw parts; emphasize liquid jet projection function
