THC Vape ISO factory audit for the EU market
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 adult smokers.

Where defects actually come from
This page is for adult smokers 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.
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.
Battery safety is not a marketing line. Cells are matched by capacity and internal resistance before assembly, charging boards are checked for cut-off voltage, and any unit that fails the cut-off test never reaches packing.
Turning shelf space into repeat visits
Seasonality in THC vape products is real but smaller than most buyers assume. The bigger swing comes from restocking discipline, not from calendar events.
Photography matters for online listings. Shoot on a neutral background with the device at a slight angle, show the pack alongside the unit, and keep the same framing across the range so the grid reads as a family.
How the price is actually built
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 60, 240 and 480 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.

Getting the carton there intact
Documentation travels with the goods: commercial invoice, packing list, and the certificate set for your market. We send a scanned copy before dispatch so your broker can clear the file in advance.
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.

Frequently asked
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.
What is the minimum order for THC vape?
Standard configurations start at 60 units per SKU, with mixed SKUs allowed inside the same carton. Custom colours, custom packaging or a private label run usually start at 240 units because of setup time on the line.
How long does production take?
Around 25 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.
