(a) Applicants may use USDA-approved technologies to augment the official USDA grading process for approved species presented for official grading. This voluntary program may be utilized by a plant at its discretion but must comply with QAD procedures to be recognized and relied upon by the official grader in conducting official duties.

(b) Applicants have the option to augment quality and yield grading services through the use of vision-based instrument technology. Instrument grading may be used as an option for determining degrees of marbling and yield factors for meat carcasses. AMS approves the grading instrument itself and its use within individual applicant facilities. Applicants may contact grading supervision to initiate the process for in-plant approval. The process for instrument grading approval at an applicant's facility is dictated through internal procedures. Final determination of quality and yield grades is made by the official grader.
