Import Tips & Compliance
• Provide core material analysis (e.g
• polyurethane foam density) to substantiate non-metallic core claim for proper duty assessment
• Label panels clearly as 'laminated steel with non-metallic core' to prevent reclassification as Chapter 73 unfinished plates
• Watch for undervaluation pitfalls; declare full panel value including core to avoid penalties
