Each handler shall promptly submit, or cause to be submitted, to the committee a copy of each certificate of inspection issued to him covering varieties so handled.

(b) With respect to any variety regulated pursuant to § 905.52(a)(4), the committee may prescribe, with the approval of the Secretary, such requirements with respect to time of inspection as it may deem necessary to insure satisfactory condition of the fruit at time of export.
