Case pack
Case pack is the number of eaches (selling units) inside one master carton. Retail replenishment, FBA box contents and WMS TI-HI all assume that number is stable. Change case pack without changing the carton and the pallet calculator still sees the same L×W×H — but the ASN and label are wrong.
Example: case pack 6, TI 16, HI 5 → 480 eaches per pallet. Changing case pack to 8 without a new carton does not change TI-HI, only the each count.
