7 CFR §800.163

1. (a)General. When shiplot grain is offered for inspection or Class X weighing as a single lot and is certificated as a single lot, the applicant may exchange the official certificate for two or more divided-lot certificates. This applies to original inspection, reinspection, appeal inspection, Board appeal inspection, and Class X weighing services.
2. (b)Application. Requests for divided-lot certificates shall be made (1) in writing; (2) by the applicant who filed the inital request; (3) to the office that issued the outstanding certificate; (4) within 5 business days of the outstanding certificate date; and (5) before the identity of the grain has been lost.
3. (c)Quantity restrictions. Divided-lot certificates shall not show an aggregate quantity different than the total quantity shown on the superseded certificate.
4. (d)Surrender of certificate. The certificate that will be superseded shall (1) be in the custody of the agency or the Service; (2) be marked “Void;” and (3) show the identification of the divided-lot certificates.
5. (e)Certification requirements. The same information and statements, including permissive statements, that were shown on the superseded certificate shall be shown on each divided-lot certificate. Divided-lot certificates shall show (1) a statement indicating the grain was inspected or weighed as an undivided lot; (2) the terms “Divided Lot-Original,” and the copies shall show “Divided Lot-Copies;” (3) the same serial number with numbered suffix (for example, 1764-1, 1764-2, 1764-3, and the like); and (4) the quantity specified by the request.
6. (f)Issuance and distribution. Divided-lot certificates shall be issued no later than the close of business on the next business day after the request and be distributed according to § 800.160.
7. (g)Limitations. No divided-lot certificate can be issued (1) for grain in any shipment other than shiplot grain inspected or weighed as a single lot or (2) for an export certificate which has been superseded by another export certificate. After divided-lot certificates have been issued, further dividing or combining is prohibited except with the approval of the Service.
8. (h)Use of superseded certificate prohibited. As of the date of the divided-lot certificate, the superseded certificate will be void and shall not be used or represent the grain.
