Appeal service is a redetermination of the class, grade, other quality, or compliance of product when the applicant for the appeal service formally challenges the correctness of the original determination. Only a person who has title to, or is a party to a contract for the sale of, a product may request appeal service with respect to such product and if the original determination of class, grade, other quality or compliance is found on appeal to have been in error all incorrect marks of class, grade, other quality and compliance will be removed from the product, and if the person having title to the product so requests, correct marks as determined on the appeal will be applied to the product. Examination requested to determine the class, grade, other quality, or compliance of a product which has been altered or has undergone a material change since the original service, or examination of product requested for the purpose of obtaining an up-to-date certificate and not involving any question as to the correctness of the original service for the product involved shall be considered equivalent to original service and not appeal service.
Grade determinations cannot be appealed for any lot or product consisting of less than 10 similar units. Moreover, appeal service will not be furnished with respect to product that has been altered or has undergone any material change since the original service.
