How to source THC Vape sample testing protocol
This page is for vape shop owners who want a working answer on specification, price and lead time before they commit a purchase order. We have written the detail down so nobody has to sit through a sales call to extract it.

Building an assortment that actually turns
We work with vape shop owners 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.
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.
Most vape shop owners arrive with a spreadsheet and leave with too many SKUs. The fix is not a bigger catalogue, it is a narrower core. We normally propose three tiers: a volume line that carries the shelf, a step-up line that lifts basket value, and one trial SKU that tells you what to order next season.
What we test before a carton is sealed
Cosmetic grading is written down, not argued about. Minor scuffs inside the tolerance band are accepted; anything that would make a customer put the unit back on the shelf is rejected. Your staff should never have to explain a finish defect to a paying customer.
Flavour drift between batches is the quiet killer of repeat orders. We retain a sealed reference sample from every run so a complaint six weeks later can be compared against what actually left the building.
Compliance without the last-minute scramble
We keep batch codes traceable from carton to production date. When a market authority asks for traceability, a supplier who cannot produce it in an hour becomes a liability very quickly.
If you sell into a market that requires child-resistant packaging, say so at quotation stage. Retrofitting a CR closure onto a finished bottle design usually means a new mould and a four week delay.
- Consolidated or split shipping, quoted both ways
- Reference sample retained from every batch
- Private label files archived for future rebrands
- Specification locked in writing before production starts
- Batch codes traceable from carton back to production date
- Seven-day defect reporting with replace-or-credit
How orders move from factory to shelf
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 25 working days after artwork approval, plus transit. We quote both routes so you can see the trade-off instead of guessing at it.
Specification summary
| Volume | 0.5 ml |
| Hardware | Cotton core |
| Thread | 510 thread |
| Airflow | Adjustable |
| Window | Side window |
| Packaging | Child-resistant box |
| Minimum order | 200 units per SKU, mixed cartons allowed |
| Lead time | 30 working days after artwork approval |
We would rather lose an order at quotation stage than explain a mismatch after delivery, which is why the specification conversation comes before the price conversation.
Frequently asked
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.
How long does production take?
Around 25 working days after artwork approval for stock configurations, plus transit. Custom runs add roughly a week for tooling and a physical dummy. We confirm the date in writing on the order acknowledgement.
