Sourcing THC Vape: factory audit checklist guide
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.

Choosing the core line
This page is for wholesale 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.
Sourcing trips still matter for volume buyers. Seeing the line, the ageing room and the packing station tells you in an hour what six emails cannot. We host visits by appointment and we do not stage them.
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.
Getting the documents right
Labels are where good orders go wrong. Nicotine warnings, child-resistant closures, batch coding and market-specific text all have to be correct before the pallet leaves. We prepare test reports, declaration of conformity and safety data sheets for each shipment and we ask for your destination list early so artwork matches the market.
Artwork approval is a two stage process: a digital proof for text and layout, then a physical dummy for colour and finish. Skipping the dummy is the single most common cause of a reprint.
Presentation that earns the step-up
Counter space is finite. Three well-chosen SKUs outsell nine crowded ones, and the empty space signals a curated range rather than a clearance table.
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.
- Document pack prepared per destination market
- Batch codes traceable from carton back to production date
- Specification locked in writing before production starts
- Mixed SKU cartons to spread first-order risk
- Seven-day defect reporting with replace-or-credit
- Cartons drop-tested and pallet-counted for clean freight
Support that answers the question
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.

Frequently asked
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.
How long does production take?
Around 20 working days after artwork approval for stock configurations, plus transit. Custom runs add roughly a week for tooling and a physical dummy. We confirm the date in writing on the order acknowledgement.
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.
