Vulcanized Natural Rubber Sheet 1mm Thick
A flat, uncut rectangular sheet of noncellular vulcanized natural rubber, 1mm thick and typically 1m x 1m in size. It falls under HTS 4008.21.00.00 as it is a simple rectangular sheet of vulcanized noncellular rubber, not further cut to shape or surface-worked beyond basic processing. These sheets are used for gaskets, liners, and industrial seals.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If made of hard rubber
Hard rubber plates/sheets are classified separately in 4008.11 due to their distinct rigidity and properties.
If unvulcanized or in primary form
Unvulcanized synthetic rubber in sheets falls under Chapter 40 primary forms, excluding vulcanized products.
If cut to specific non-rectangular shapes for use as articles
Sheets further worked or cut to shape become other articles of vulcanized rubber, not simple plates/sheets.

Import Tips & Compliance
• Verify the rubber is noncellular (no foam structure) via density testing to confirm classification under 4008.21
• Provide mill test certificates showing vulcanization and composition to avoid misclassification as unvulcanized rubber (4002)
• Ensure sheets are rectangular and not custom-cut to article shapes, which would shift to heading 4016
