Commercial terms
Freight terms should be named explicitly, because an unclear incoterm is the fastest way to lose a relationship.
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 (104 units) | Tier 1 | 21-30 days |
| Pallet (979 units) | Tier 2 | 14-21 days |
| Container (8882 units) | Tier 3 | 21-30 days |
Frequently asked questions
How often should Diamond 4 be cleaned?
A quick contact clean every week or two, with a fuller clean monthly, suits most usage patterns.
Is documentation provided for customs?
Commercial invoice, packing list and the relevant certificates are supplied; the importer's broker handles the declaration.
Can packaging be adjusted for our market?
Artwork localisation is straightforward; structural changes need larger volumes and a longer lead time.
Do you support long term supply agreements?
Yes, rolling agreements with defined review points work better for both sides than rigid annual commitments.
Final word
A short quarterly review of these points will keep the Diamond 4 range healthy without consuming the week.
