Sourcing THC Vape: commercial invoice workbook
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.

Where defects actually come from
This page is for adult smokers 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.
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.
Labels, closures and traceability
Advertising rules are stricter than product rules in most markets. Claims about cessation, health or comparative performance should stay off packaging and off your product pages unless your legal team has signed them off.
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.
What happens when something goes wrong
Reorders are the real test of a supplier. If the second shipment does not match the first, the relationship is over regardless of price, so we treat the reorder as the actual deliverable.
Technical questions usually arrive at the worst possible moment, which is why we answer them on WhatsApp as well as email. A photo and a two line message resolves most issues faster than a ticket.
- Batch codes traceable from carton back to production date
- Mixed SKU cartons to spread first-order risk
- Seven-day defect reporting with replace-or-credit
- Document pack prepared per destination market
- Specification locked in writing before production starts
- Private label files archived for future rebrands
Merchandising a small range well
Seasonality in THC vape products is real but smaller than most buyers assume. The bigger swing comes from restocking discipline, not from calendar events.
Bundle a device with a consumable and the reorder rhythm changes from occasional to weekly. That single merchandising decision often does more for monthly revenue than a price promotion.

If any of this is unclear, the fastest route is a message rather than a meeting. Send the market you sell into and the price band you work in, and you will get a specific answer instead of a brochure.
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.
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.
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 60 units. We would rather you handle the sample than approve a specification from a photograph.
