Rule 9. A shipper, owner, or seller of an officially certified lot of beans is entitled to reinspection at the point of origin if he or she has sufficient grounds to differ with the grading of the lot by the inspector making the original point of origin inspection. The request for a reinspection shall be filed with the chief inspector. The chief inspector shall supervise or direct the resampling or he or she may use the inspector's sample for analysis. If the chief inspector's grading differs from the original inspector's grading, then all copies of the certificate covering the first inspection shall be surrendered and a new certificate shall be issued by the chief inspector. If the grading of the first inspector is confirmed, then the applicant for a reinspection shall bear all additional costs incurred in connection with the reinspection.
