Grain Standards Improvement Act of 2000

Grain Standards Improvement Act of 2000 - Amends the United States Grain Standards Act to extend: (1) the Secretary of Agriculture's grain inspection and weighing fee authorities; (2) advisory committee authority; (3) administrative and supervisory cost limitations; and (4) authorization of appropriations. Reduces permitted administrative and supervisory costs.

Eliminates the requirement that: (1) grain export inspection and weighing samples be taken from certain physical locations (spout or final carrier); and (2) equipment be tested annually.

Authorizes the Secretary to: (1) allow official multi-site inspection and weighing services within a single geographic area (eliminates pilot program designation); and (2) prohibit the use of grain additives to disguise grain quality.
