Commercial terms
Agreeing a defect handling procedure before the first shipment removes emotion from later conversations.
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 (70 units) | Tier 1 | 21-30 days |
| Pallet (780 units) | Tier 2 | 7-12 days |
| Container (9715 units) | Tier 3 | 14-21 days |
Frequently asked questions
Why does batch traceability matter for Meta 4?
It limits the scope of any future quality action to the affected batch instead of the whole range.
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.
Can several models be mixed in one shipment?
Yes, mixing models and flavours within a carton or pallet is common and usually helps first time buyers test demand.
Can packaging be adjusted for our market?
Artwork localisation is straightforward; structural changes need larger volumes and a longer lead time.
Final word
A short quarterly review of these points will keep the Meta 4 range healthy without consuming the week.
