(b) Minimum biobased content. The preferred procurement product must have a biobased content of at least 49 percent, which shall be based on the amount of qualifying biobased carbon in the product as a percent of the weight (mass) of the total organic carbon in the finished product. If the finished product is to be diluted before use, the biobased content of the cleaner must be determined before dilution.

(c) Preference compliance date. No later than May 14, 2009, procuring agencies, in accordance with this part, will give a procurement preference for qualifying biobased glass cleaners.
