(a) Definition. Products formulated to provide light lubrication and corrosion resistance in close tolerant internal and external applications including frozen nuts and bolts, power tools, gears, valves, chains, and cables.

(b) Minimum biobased content. The minimum biobased content is 68 percent and 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.

(c) Preference effective date. No later than March 16, 2007, procuring agencies, in accordance with this part, will give a procurement preference for qualifying biobased penetrating lubricants. By that date, Federal agencies that have the responsibility for drafting or reviewing specifications for items to be procured shall ensure that the relevant specifications require the use of biobased penetrating lubricants.

(d) Determining overlap with an EPA-designated recovered content product. Qualifying biobased products that fall under this item may, in some cases, overlap with the following EPA-designated recovered content product: Re-refined Lubricating Oils. USDA is requesting that manufacturers of these qualifying biobased products provide information for the BioPreferred Web site of qualifying biobased products about the intended uses of the product, information on whether or not the product contains petroleum-based ingredients, re-refined oil, and/or any other recovered material, in addition to biobased ingredients, and performance standards against which the product has been tested. This information will assist Federal agencies in determining whether or not a qualifying biobased product overlaps with EPA-designated lubricating oils containing re-refined oil and which product should be afforded the preference in purchasing.
