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 (58 units) | Tier 1 | 30-45 days |
| Pallet (1975 units) | Tier 2 | 30-45 days |
| Container (18233 units) | Tier 3 | 7-12 days |
Frequently asked questions
Can airflow be adjusted on Bold S?
Most current designs include a rotating ring or sliding switch; confirm the exact mechanism on the specification sheet.
How quickly can a repeat order be produced?
For established configurations production typically runs two to four weeks, with transit on top depending on the chosen method.
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.
