Sourcing THC Vape: factory audit checklist overview
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 B2B buyers.

Where the margin really sits
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.
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.
Custom printing raises the unit price and lowers the marketing cost. For B2B buyers the break-even is usually reached on the second or third repeat order, not the first, so we quote both branded and neutral options.
Where defects actually come from
11 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.
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.
After-sales, replacements and reorders
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.
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.
- Batch codes traceable from carton back to production date
- Private label files archived for future rebrands
- Document pack prepared per destination market
- Specification locked in writing before production starts
- Mixed SKU cartons to spread first-order risk
- Named account contact who has handled the product
What a sensible opening order looks like
The first question we ask is not what you want to spend. It is what your customer already buys. Answer that and the THC vape list writes itself; skip it and you end up with a pallet of stock that photographs well and sells badly.
Most B2B 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.

Frequently asked
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 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.
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 300 units. We would rather you handle the sample than approve a specification from a photograph.
