Commercial terms

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

Agreeing a defect handling procedure before the first shipment removes emotion from later conversations.

Volume tier	Indicative unit level	Lead time
Carton (71 units)	Tier 1	14-21 days
Pallet (861 units)	Tier 2	30-45 days
Container (18085 units)	Tier 3	14-21 days

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