Production of R12 or CFC-12 was halted by the clean air act on January 1, 1996. Today the remaining supplies are product which has been recovered and reclaimed back to a chemically pure state in accordance with ARI-700 standards. The ARI-700 standard is basically a virgin specification. The supply of virgin product is limited as most of the virgin was depleted in the first and second years after production ceased. PRODUCTION CEASED IN 1995
