THC Vape defect rate for new brands guide
Buyers come to us for THC vape after a bad quarter: dead stock on one side, empty shelves on the other. The cause is usually the same, an assortment built from a catalogue instead of from sell-through data. This page explains how we rebuild that balance for first-time buyers.

Quality control, in plain terms
This page is for first-time buyers 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.
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.
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.
Sell-through notes for the shop floor
Photography matters for online listings. Shoot on a neutral background with the device at a slight angle, show the pack alongside the unit, and keep the same framing across the range so the grid reads as a family.
Shelf position decides velocity as much as price. Keep THC vape products at eye level, one facing per SKU, and rotate the trial line every quarter so the display keeps earning attention.
Reading a quotation properly
Currency moves more than most buyers expect over a twelve month supply plan. We quote in USD and hold the price for 30 days from confirmation so your margin calculation is not guesswork.
Unit price breaks usually land at 300, 800 and 1600 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.
- Specification locked in writing before production starts
- Mixed SKU cartons to spread first-order risk
- Named account contact who has handled the product
- Document pack prepared per destination market
- Private label files archived for future rebrands
- Cartons drop-tested and pallet-counted for clean freight
What a sensible opening order looks like
A practical starting order for first-time buyers is 300 units across two or three SKUs, not 300 units of one. That spreads the risk, gives your staff something to compare, and still hits the first price break.
Most first-time buyers 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.
Specification summary

| Thread | Proprietary pod |
| Airflow | Adjustable |
| Window | Full glass |
| Packaging | Tube |
| Minimum order | 50 units per SKU, mixed cartons allowed |

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 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.
What is the minimum order for THC vape?
Standard configurations start at 300 units per SKU, with mixed SKUs allowed inside the same carton. Custom colours, custom packaging or a private label run usually start at 800 units because of setup time on the line.
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.
