Which statement is true about the pre-shipment review?

The statement that product is considered "produced and shipped" once the pre-shipment review is signed highlights the significance of this review in the overall process of product compliance and safety verification. A pre-shipment review serves as a critical checkpoint that ensures all necessary standards and regulations have been met prior to the product leaving the facility. Upon signing the review, it indicates that all conditions for safe shipment have been satisfied, ultimately confirming that the product is ready for distribution.

This aspect underscores the importance of the pre-shipment review in the context of ensuring that products are compliant with USDA regulations before they are sent to market. Hence, once the review is approved, it essentially authorizes the shipment, marking a definitive point in the product's compliance journey from production to market.

The other statements pertain to nuances of the review process itself, such as its variability in execution, timing with respect to the product's entry into commerce, and its mandatory nature versus being merely suggestive, but they do not hold the same definitive impact regarding the immediate classification of the product's shipping status upon completion of the review.
