Despite newer revisions, the -13 edition is still written into RFQs, master distribution agreements, and retailer vendor manuals because it established the Distribution Cycle (DC) structure the industry standardized on. Understanding it precisely protects you from over-testing costs, failed audits, and downstream freight damage claims.
