Commercial terms

Volume commitments work best when they are structured as a rolling target rather than a single fixed number.

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 (88 units)	Tier 1	7-12 days
Pallet (1999 units)	Tier 2	21-30 days
Container (8865 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.
