40.03 ‑ Reclaimed rubber in primary forms or in plates, sheets or strip.
Reclaimed rubber is obtained from used rubber articles, especially tyres, or from waste or scrap, of vulcanised rubber, by softening ("devulcanising") the rubber and removing some of the unwanted matter by various chemical or mechanical means. The product contains residues of sulphur or other vulcanising agents in combination and is inferior to virgin rubber, being more plastic and more tacky than virgin rubber. It may be put up in sheets dusted with talc or separated by polyethylene film. This heading covers reclaimed rubber in primary forms or in plates, sheets or strip, whether or not mixed with virgin rubber or other added substances, provided that the product has the essential character of reclaimed rubber.
