Commercial terms

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

Freight terms should be named explicitly, because an unclear incoterm is the fastest way to lose a relationship.

Volume tier	Indicative unit level	Lead time
Carton (50 units)	Tier 1	21-30 days
Pallet (1548 units)	Tier 2	14-21 days
Container (13999 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.
