Import Tips

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
