Published 2026 · VapeWholesaleHub trade desk

A disciplined sample workflow shortens the path from first interest to a Box 4 purchase order.
A range review that ignores sample order workflow will often produce a confident decision and a disappointing quarter on the Box 4.
Where two suppliers look identical on price, sample order workflow is usually the variable that separates them over a full year.
Why sample order workflow matters on the Box 4
Request samples with the final specification, not an approximation.
Keeping a short internal note on sample order workflow for each SKU pays for itself the first time a dispute arises over the Box 4.

Commercial terms
Lead times are a function of component availability as much as factory capacity, so buffers should reflect both.
Payment history is the single most reliable route to better terms, more than total annual volume.

| Pallet (1389 units) | Tier 2 | 21-30 days |
| Container (10169 units) | Tier 3 | 14-21 days |
Frequently asked questions
How many Box 4 samples should we request?
Three to five units per shortlisted configuration is enough to judge consistency.
Can packaging be adjusted for our market?

Commercial invoice, packing list and the relevant certificates are supplied; the importer's broker handles the declaration.
