THC Vape airflow tuning deep dive
A THC vape programme only works when three numbers agree: your shelf price, your reorder cycle and your defect tolerance. Change one and the plan moves. We build assortments around those three and we say so up front rather than after the invoice.

The checks behind every shipment
This page is for importers 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.
Battery safety is not a marketing line. Cells are matched by capacity and internal resistance before assembly, charging boards are checked for cut-off voltage, and any unit that fails the cut-off test never reaches packing.
We photograph the packing station during production for volume orders. It is a small thing, but it settles most arguments about what was actually in the carton before it was sealed.
Choosing the core line
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 importers 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.
Where the margin really sits
Unit price breaks usually land at 240, 600 and 1200 pieces. Between those steps the cost curve flattens, which is why pushing a 200 unit order to 500 often costs less per unit than buyers expect.
We publish a realistic band of 3.55 to 9.68 per unit for standard configurations at 240 units. Below that band you are buying a lighter specification; above it you are paying for finish, packaging or a smaller run.
- Cartons drop-tested and pallet-counted for clean freight
- Reference sample retained from every batch
- Named account contact who has handled the product
- Batch codes traceable from carton back to production date
- Consolidated or split shipping, quoted both ways
- Specification locked in writing before production starts
What happens when something goes wrong
Every account gets a named contact who has actually seen the product. Being passed between three people to answer one question about a coil resistance is the fastest way to lose a buyer, so we do not organise support that way.
Returns are handled as data, not as complaints. Every reported failure is logged by mode and by batch, and the pattern is reviewed monthly with the factory.
Specification summary
| Volume | 0.5 ml |
| Hardware | Cotton core |
| Thread | 510 thread |
| Airflow | Adjustable |
| Window | Side window |
| Packaging | Child-resistant box |
| Minimum order | 300 units per SKU, mixed cartons allowed |
| Lead time | 18 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
Can you ship to multiple locations?
Yes. Split shipments are quoted separately because consolidation and splitting price differently. Tell us the destination list at quotation stage and we will show both options.
Do you support private label?
We do. Send your artwork or your brand direction and we will return a digital proof, then a physical dummy for colour approval. Packaging files stay on record so a rebrand later is a file update rather than a redesign.
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.
