Review the reorder point after one full selling cycle.
Verify that artwork matches the approved compliance template.
Keep certificates current and filed against the exact model name.

Log sell through by account for the first eight weeks.

Lead times are a function of component availability as much as factory capacity, so buffers should reflect both.

Volume tier	Indicative unit level	Lead time
Carton (134 units)	Tier 1	30-45 days
Pallet (1699 units)	Tier 2	21-30 days
Container (15048 units)	Tier 3	30-45 days

All figures above are indicative working ranges used for planning. Final specification and commercial terms are confirmed in writing before any deposit.
