TSNR L Grade Natural Rubber Sheets
Technically specified natural rubber (TSNR) L grade in sheet form, produced from coagulated latex with controlled dirt content and Mooney viscosity for industrial applications. Classified under HTS 4001.22.0050 as TSNR 'other' in primary forms like sheets, meeting chapter note definitions for natural rubber not compounded with vulcanizing agents. Essential raw material for tire manufacturing and rubber products.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If in latex form (liquid dispersion)
Latex qualifies as primary liquid form under note 3(a), distinct from coagulated sheet forms like TSNR.
If from manufacturing waste or parings
Waste, parings, or scrap from rubber processing fall under 4004 per note 6, not primary TSNR.
If synthetic rubber mixture
Mixtures with synthetic rubber lose natural rubber classification, moving to synthetic primary forms.

Import Tips & Compliance
• Verify TSNR certification and technical specs (e.g
• dirt retention <0.20%, Mooney viscosity) match HTS primary form requirements to avoid reclassification as compounded rubber
• Provide mill test certificates showing no vulcanizing agents, pigments, or extenders per chapter note 5 to confirm eligibility under 4001
