Sourcing THC Vape: third-party testing brief
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 retail buyers.

Unit price versus landed cost
A THC vape programme only works when three numbers agree: your shelf price, your reorder cycle and your defect tolerance. Change one and the plan moves. We build assortments around those three and we say so up front rather than after the invoice.
Freight is quoted separately and honestly. Bundling it into the unit price looks tidy and hides the one line that changes most often between shipments.
Unit price breaks usually land at 500, 1000 and 2000 pieces. Between those steps the cost curve flattens, which is why pushing a 200 unit order to 500 often costs less per unit than buyers expect.
The checks behind every shipment
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.
Flavour drift between batches is the quiet killer of repeat orders. We retain a sealed reference sample from every run so a complaint six weeks later can be compared against what actually left the building.
After-sales, replacements and reorders
We keep the specification sheet for every order on file. Two years later, when a customer asks whether a pod is compatible, the answer is a lookup rather than a guess.
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.
- Private label files archived for future rebrands
- Mixed SKU cartons to spread first-order risk
- Batch codes traceable from carton back to production date
- Standing reorder schedule with a fixed cut-off
- Seven-day defect reporting with replace-or-credit
- Consolidated or split shipping, quoted both ways
Labels, closures and traceability
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.
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.

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 we order samples before committing?
Yes. Sample orders are shipped by air express and the cost is credited against your first production order above 500 units. We would rather you handle the sample than approve a specification from a photograph.
How long does production take?
Around 30 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.
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.
