Import Tips
• Specify strip dimensions in invoices; overly narrow strips might be viewed as profiles under different subheadings
• Include origin certificates for cork sourcing, as EU regulations may apply to agglomerated cork products
• Test for density compliance; insufficient compression could reclassify as loose fill under other codes
