The committee, with the approval of the Secretary, may prescribe adequate safeguards to prevent shipments pursuant to § 946.54 from entering channels of trade and other outlets for other than the specific purposes authorized therefor, and the transportation of potatoes for grading and storing to points outside the production area.

Safeguards provided by this section may include, but shall not be limited to, requirements that handlers:

Shall obtain the inspection required by § 946.60 or pay the assessment provided by § 946.41, or both, in connection with the potato shipments effected in accordance with § 946.54, and

Shall obtain a special purpose certificate from the committee for shipments of potatoes effected or to be effected under provisions of § 946.54.

The committee, with the approval of the Secretary, shall prescribe rules governing the issuance and the contents of the special purpose certificate.

The committee may rescind, or deny to any handler the special purpose certificate if proof satisfactory to the committee is obtained that potatoes shipped by him for the purpose stated in § 946.54 were handled contrary to the provisions of this section.

The committee shall make reports to the Secretary, as requested, showing the number of applications for such certificates, the quantity of potatoes covered by such applications for such certificates, the number of such applications denied, and certificates granted, the quantity of potatoes shipped under duly issued certificates, and such other information as may be requested by the Secretary.
