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 checks behind every shipment
We ship THC vape products to distributors, chain buyers and independent shops. What follows is the material we normally cover in a first conversation: what we hold in stock, how we test it, how it ships, and what happens when a carton arrives damaged.
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.
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.
The reorder is the real test
We keep the specification sheet for every order on file. Two years later, when a customer asks whether a pod is compatible, the answer is a lookup rather than a guess.
Every account gets a named contact who has actually seen the product. Being passed between three people to answer one question about a coil resistance is the fastest way to lose a buyer, so we do not organise support that way.
Unit price versus landed cost
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.
Custom printing raises the unit price and lowers the marketing cost. For B2B buyers the break-even is usually reached on the second or third repeat order, not the first, so we quote both branded and neutral options.
- Reference sample retained from every batch
- Named account contact who has handled the product
- Cartons drop-tested and pallet-counted for clean freight
- Mixed SKU cartons to spread first-order risk
- Document pack prepared per destination market
- Standing reorder schedule with a fixed cut-off
What a sensible opening order looks like
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.
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.

Frequently asked
How long does production take?
Around 28 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.
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.
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.
