Commercial terms

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

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

Volume tier	Indicative unit level	Lead time
Carton (138 units)	Tier 1	30-45 days
Pallet (610 units)	Tier 2	30-45 days
Container (13382 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.

What happens if a batch fails inspection?

The agreed procedure normally covers replacement of affected units or credit against the next order, documented before shipment.

A short quarterly review of these points will keep the Nex 4 range healthy without consuming the week.
