Why cosmetics MRP is different
Generic MRP nets demand against a bill of materials and stock. In cosmetics, the bill of materials is a formula that changes with approved substitutions, raw materials expire, and quarantined lots look like available stock until someone checks. Contract manufacturers add customer-specific specifications and packaging on top.
The question to ask any vendor is simple: when a formula, lot status or order changes, does the plan update on its own, or does a planner rebuild it?
