✓ Inside the checklist
→ Every new threshold by size tier — standard, oversize, and extra-large, with before/after numbers
→ Step-by-step instructions to pull your current speed metrics from Seller Central (Inventory tab and Account Health)
→ The size tier misclassification check — the compliance gap most sellers don't audit until after they lose the badge
→ The carrier and warehouse questions to ask before July 6, including the weekend shipping issue that becomes a hard enforcement problem on October 17
July 6 is gone. Sellers who miss the new thresholds lose the Prime badge and exit the Buy Box pool — without warning.
