For Amazon PL sellers — restock limits, ACOS vs TACOS, ungating documents, and the supply chain behind your BSR.
Ungating is not a product-quality review. It is a liability question, and it is answered with factory-level certificates and batch-level records — which is exactly what a trading company cannot supply.
ACOS measures one campaign. TACOS measures the business. Confusing them leads sellers to optimise the number that is easiest to see rather than the one that decides whether the product is viable.
Sellers treat restock limits as a platform policy to be worked around. The binding constraint is the eight to twelve weeks between placing an order and having sellable inventory.
