THC Vape sample testing protocol with full documents
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 private label sellers.

Labels, closures and traceability
We work with private label sellers who order between a few hundred and a few thousand units at a time, and we treat both ends the same way: a written specification, a sample you approve, and a production run that matches the sample.
Regulation for THC vape products differs by country and sometimes by state. We do not pretend to be your lawyer, but we do keep the document pack current and we will tell you when a configuration cannot legally enter a market you have named.
If you sell into a market that requires child-resistant packaging, say so at quotation stage. Retrofitting a CR closure onto a finished bottle design usually means a new mould and a four week delay.
Where the margin really sits
Custom printing raises the unit price and lowers the marketing cost. For private label sellers the break-even is usually reached on the second or third repeat order, not the first, so we quote both branded and neutral options.
We publish a realistic band of 3.40 to 9.86 per unit for standard configurations at 500 units. Below that band you are buying a lighter specification; above it you are paying for finish, packaging or a smaller run.
Building an assortment that actually turns
When you compare suppliers for THC vape, ask for the last three production dates on the same SKU. If the answers are vague, the specification is not being held and the next batch will not match the sample you approved.
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.
- Batch codes traceable from carton back to production date
- Seven-day defect reporting with replace-or-credit
- Document pack prepared per destination market
- Mixed SKU cartons to spread first-order risk
- Artwork proof plus physical dummy for custom packaging
- Specification locked in writing before production starts
After-sales, replacements and reorders
For private label accounts we hold the artwork files and the approval record. Rebranding a line eighteen months later is then a file update instead of a redesign.
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 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 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.
Do you support private label?
We do. Send your artwork or your brand direction and we will return a digital proof, then a physical dummy for colour approval. Packaging files stay on record so a rebrand later is a file update rather than a redesign.
