How to source THC Vape defect rate 2027
There is no shortage of suppliers quoting THC vape. The scarce thing is a supplier who will tell you which SKU to drop. We have been shipping THC vape products long enough to know that the honest answer is usually a shorter list, and that is the answer we give.

Turning shelf space into repeat visits
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.
Seasonality in THC vape products is real but smaller than most buyers assume. The bigger swing comes from restocking discipline, not from calendar events.
Staff knowledge converts better than any poster. If your team can explain the difference between two coils in one sentence, the step-up SKU sells itself.
Where defects actually come from
10 separate checks run before a carton is sealed: electrical, mechanical, leak, finish and packaging. Anything outside tolerance is quarantined the same day and reported to you, rather than shipped with a hope and a discount.
A 0.5 percent defect rate sounds excellent until it lands on a 600 unit order and you are handling three returns in a week. We quote realistic rates per category and we credit in advance for the known failure modes.
Price breaks and payment terms
A landed cost sheet for THC vape has five lines: unit price, packaging, freight, duty and the cost of defects. Quoting only the first line is how buyers end up surprised at the fourth.
Payment terms for new accounts are normally a deposit with the balance against the bill of lading. Established buyers on a repeat schedule can move to terms after three clean shipments.
- Mixed SKU cartons to spread first-order risk
- Cartons drop-tested and pallet-counted for clean freight
- Consolidated or split shipping, quoted both ways
- Named account contact who has handled the product
- Seven-day defect reporting with replace-or-credit
- Document pack prepared per destination market
How orders move from factory to shelf
We ship from Shenzhen and Guangzhou: air express for samples and part loads, sea freight for volume. Typical production lead time is 12 working days after artwork approval, plus transit. We quote both routes so you can see the trade-off instead of guessing at it.
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.

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 240 units. We would rather you handle the sample than approve a specification from a photograph.
How do you handle repeat orders?
The specification is held on file against your account, so a reorder is a reference rather than a new brief. We recommend a standing schedule with a fixed weekly cut-off so stock lands before the shelf empties.
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.
