TSNR Grade 5 Ribbed Smoke Sheet
Technically Specified Natural Rubber (TSNR) Grade 5 is a lightly smoked sheet made from coagulated natural latex, processed to meet specific technical standards for quality and consistency. It falls under HTS 4001.22.00.05 as it is TSNR in primary sheet form, with moderate dirt content and ash levels suitable for mid-range industrial applications. This form retains the essential character of raw natural rubber without prohibited compounding.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If in smoked sheets but meets Grade 10 specs
Higher quality smoked sheets (lower impurities) classify under TSNR other grades like Grade 10 in 4001.21.
If compounded with vulcanizing agents or fillers
Chapter note 5(a) excludes rubber mixed with vulcanizing agents from headings 4001-4003, moving to waste or compounded forms.
If in latex form rather than sheets
Latex is a primary liquid form under 4001.11, while sheets are 'other forms' in 4001.22 for TSNR.

Import Tips & Compliance
• Verify supplier certification confirming TSNR Grade 5 specs (e.g
• DIRTMAT ≤0.20%, nitrogen ≤0.60%) to avoid reclassification as lower grades
• Include lab test reports for ash, dirt, and plasticity retention index (PRI) in documentation for CBP examination
• Ensure no vulcanizing agents or fillers added, as this would shift to heading 4004 or exclude from primary forms
