Neoprene Foam Sheet from China
A flexible sheet made from cellular vulcanized neoprene rubber, used for gaskets, seals, and insulation in industrial applications. It falls under HTS 4008.19.80.00 as it is a plate/sheet of cellular rubber, other than hard rubber, not specifically provided for elsewhere. The cellular structure provides compressibility and buoyancy.

Import Tips
• Verify cellular structure via density testing (<0.92 g/cm³ typical for foam) to confirm classification under cellular rubber subheading
• Provide manufacturer specs confirming vulcanized cellular rubber composition, excluding hard rubber (durometer >95 Shore A)
• Avoid misclassification as non-cellular by ensuring documentation shows foam/sponge structure, not solid rubber sheets
