How to source THC Vape defects in bulk
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 brand owners.

Where defects actually come from
We work with brand owners 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.
We photograph the packing station during production for volume orders. It is a small thing, but it settles most arguments about what was actually in the carton before it was sealed.
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.
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.
How we structure a first order
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.
Colour range is where assortments quietly die. Six finishes look impressive in a brochure and disastrous on a shelf with 40 cm of space. We recommend two finishes per core SKU and let the trial line carry the novelty.
- Document pack prepared per destination market
- Cartons drop-tested and pallet-counted for clean freight
- Consolidated or split shipping, quoted both ways
- Artwork proof plus physical dummy for custom packaging
- Reference sample retained from every batch
- Named account contact who has handled the product
Price breaks and payment terms
We publish a realistic band of 3.32 to 9.33 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.
Unit price breaks usually land at 300, 800 and 1600 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.

We would rather lose an order at quotation stage than explain a mismatch after delivery, which is why the specification conversation comes before the price conversation.
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 is the minimum order for THC vape?
Standard configurations start at 300 units per SKU, with mixed SKUs allowed inside the same carton. Custom colours, custom packaging or a private label run usually start at 800 units because of setup time on the line.
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.
