Sourcing THC Vape: ISO factory audit tips
THC Vape is a specification decision before it is a price decision. Get the resistance, the capacity and the packaging right and the price conversation becomes short. Get them wrong and no discount will rescue the order.

Getting the carton there intact
This page is for smoke shop owners 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.
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.
We can consolidate mixed orders of THC vape products into one shipment. Consolidation saves freight but adds handling days, so we quote both a consolidated and a split option and let you choose.
Presentation that earns the step-up
Seasonality in THC vape products is real but smaller than most buyers assume. The bigger swing comes from restocking discipline, not from calendar events.
Counter space is finite. Three well-chosen SKUs outsell nine crowded ones, and the empty space signals a curated range rather than a clearance table.
Where defects actually come from
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.
Cosmetic grading is written down, not argued about. Minor scuffs inside the tolerance band are accepted; anything that would make a customer put the unit back on the shelf is rejected. Your staff should never have to explain a finish defect to a paying customer.
- Artwork proof plus physical dummy for custom packaging
- Consolidated or split shipping, quoted both ways
- Reference sample retained from every batch
- Named account contact who has handled the product
- Cartons drop-tested and pallet-counted for clean freight
- Batch codes traceable from carton back to production date
Price breaks and payment terms
Custom printing raises the unit price and lowers the marketing cost. For smoke shop owners the break-even is usually reached on the second or third repeat order, not the first, so we quote both branded and neutral options.
Payment terms for new accounts are normally a deposit with the balance against the bill of lading. Established buyers on a repeat schedule can move to terms after three clean shipments.

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
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.
