Flexible tubing made from unvulcanized natural rubber in continuous lengths, used in manufacturing processes before vulcanization. It falls under HTS 4006.90.10.00 as 'tubes' of unvulcanized natural rubber, distinct from vulcanized forms or primary shapes in earlier headings. This form allows easy shaping during final production.

Import Tips
• Verify the rubber is truly unvulcanized through lab testing, as vulcanized forms shift to heading 4008; provide certificates of analysis confirming natural rubber content without vulcanizing agents
• Ensure documentation distinguishes from latex (4001) or sheets (4006.10)
