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 (107 units)	Tier 1	30-45 days
Pallet (860 units)	Tier 2	7-12 days
Container (14191 units)	Tier 3	7-12 days

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