THC Vape factory audit checklist for the US market
If you are comparing three quotes for THC vape, compare the paperwork first. Test reports, artwork files, batch coding and the replacement clause tell you more about a supplier than the unit price on page one.

Assortment planning without the guesswork
We work with importers who order between a few hundred and a few thousand units at a time, and we treat both ends the same way: a written specification, a sample you approve, and a production run that matches the sample.
When you compare suppliers for THC vape, ask for the last three production dates on the same SKU. If the answers are vague, the specification is not being held and the next batch will not match the sample you approved.
Factory capacity matters more than factory size. A line that can hold a tolerance across 5,000 units is worth more than a showroom that can produce 50,000 on paper. We qualify capacity by running a repeat order and measuring the drift.
Transit, consolidation and timing
Freight on THC vape products is driven by volume more than weight. Cartons are designed to hit a clean pallet count, which is why a slightly denser pack can cut your landed cost by more than a discount on the unit price ever would.
We ship from Shenzhen and Guangzhou: air express for samples and part loads, sea freight for volume. Typical production lead time is 18 working days after artwork approval, plus transit. We quote both routes so you can see the trade-off instead of guessing at it.
Labels, closures and traceability
Artwork approval is a two stage process: a digital proof for text and layout, then a physical dummy for colour and finish. Skipping the dummy is the single most common cause of a reprint.
Age verification is not only a website problem. Retail packaging, shelf placement and staff scripting all carry compliance weight, and auditors increasingly ask for evidence of all three.
- Batch codes traceable from carton back to production date
- Specification locked in writing before production starts
- Artwork proof plus physical dummy for custom packaging
- Reference sample retained from every batch
- Seven-day defect reporting with replace-or-credit
- Cartons drop-tested and pallet-counted for clean freight
Where the margin really sits
We publish a realistic band of 3.51 to 9.58 per unit for standard configurations at 100 units. Below that band you are buying a lighter specification; above it you are paying for finish, packaging or a smaller run.
Custom printing raises the unit price and lowers the marketing cost. For importers the break-even is usually reached on the second or third repeat order, not the first, so we quote both branded and neutral options.

None of this is complicated. It is just written down, which is more than most buyers get before they wire a deposit.
Frequently asked
Can we order samples before committing?
Yes. Sample orders are shipped by air express and the cost is credited against your first production order above 100 units. We would rather you handle the sample than approve a specification from a photograph.
What documents come with a shipment?
Commercial invoice, packing list, and the certificate pack for your market: test reports, declaration of conformity and safety data sheets. We send scans before dispatch so your broker can pre-clear the file.
What happens if part of the order is defective?
Report within seven days with photos and the batch code. Confirmed defects are replaced or credited on the next shipment. The failure is logged by mode and batch, and reviewed monthly with the factory.
