On February 21, 2017, USDA announced in the Federal Register that the comment period for the Designation of Product Categories for Federal Procurement proposed rule had been extended.  The proposed rule aims to amend the Guidelines for Designating Biobased Products for Federal Procurement to add 12 product categories composed of intermediate ingredient and feedstock materials and to propose a minimum biobased content for each category.  In addition to the product categories and biobased content, USDA is seeking comments on appropriate performance standards for each product category, the positive environmental and human health attributes of biobased products within the proposed categories, and how small businesses may be affected by the proposed rule.  Comments are now due by April 13, 2017.
