THC Vape QC steps — 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 B2B buyers.

What happens when something goes wrong
This page is for B2B 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.
The replacement policy is deliberately simple: report within seven days of delivery with photos and the batch code, and we replace or credit at the next shipment. We do not argue about a defect we can see in a photograph.
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.
Batch consistency and why it matters
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.
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.
What a sensible opening order looks like
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.
We source THC vape products from a small group of factories we have worked with for years. That means a specification can be held across repeat orders instead of being re-qualified from scratch every quarter. Consistency is a boring selling point and it is also the entire game.
- 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
- Reference sample retained from every batch
- Standing reorder schedule with a fixed cut-off
Reading a quotation properly
We publish a realistic band of 3.24 to 10.25 per unit for standard configurations at 300 units. Below that band you are buying a lighter specification; above it you are paying for finish, packaging or a smaller run.
A landed cost sheet for THC vape has five lines: unit price, packaging, freight, duty and the cost of defects. Quoting only the first line is how buyers end up surprised at the fourth.

None of this is complicated. It is just written down, which is more than most buyers get before they wire a deposit.
Frequently asked
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.
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.
