Sourcing THC Vape: sample testing protocol walkthrough
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.

Shipping without surprises
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.
If you dropship, we can label cartons to your format and omit our documentation from the outer box. It is a small operational detail that decides whether your customer sees a supplier or a partner.
For repeat buyers we hold a shipping schedule rather than shipping on request. A fixed weekly cut-off means your reorder lands before the shelf empties instead of after.
Presentation that earns the step-up
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.
Shelf position decides velocity as much as price. Keep THC vape products at eye level, one facing per SKU, and rotate the trial line every quarter so the display keeps earning attention.
Quality control, in plain terms
Leak complaints almost always trace back to one of three things: an over-torqued centre post, a seal that sat in a hot container, or a fill volume pushed past the design limit. We cap fill volume slightly below maximum for exactly that reason.
9 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.
- Reference sample retained from every batch
- Standing reorder schedule with a fixed cut-off
- Cartons drop-tested and pallet-counted for clean freight
- Batch codes traceable from carton back to production date
- Consolidated or split shipping, quoted both ways
- Document pack prepared per destination market
Building an assortment that actually turns
A practical starting order for private label sellers is 200 units across two or three SKUs, not 200 units of one. That spreads the risk, gives your staff something to compare, and still hits the first price break.
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.

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
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.
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.
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.
