How to source THC Vape spare parts with COA
We work with B2B buyers 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.

What your market will ask for
THC Vape sits in a crowded price band, and the cheapest quote on the sheet is rarely the cheapest unit on your shelf. Everything below is built around reorder rate, defect rate and cash conversion rather than headline unit price.
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.
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.
How we structure a first order
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.
Price breaks and payment terms
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.
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.
- Batch codes traceable from carton back to production date
- Specification locked in writing before production starts
- Reference sample retained from every batch
- Mixed SKU cartons to spread first-order risk
- Named account contact who has handled the product
- Document pack prepared per destination market
The reorder is the real test
For private label accounts we hold the artwork files and the approval record. Rebranding a line eighteen months later is then a file update instead of a redesign.
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.
Specification summary
| Volume | 1.0 ml |
| Hardware | Cotton core |
| Thread | Proprietary pod |
| Airflow | Adjustable |
| Window | Full glass |
| Packaging | Child-resistant box |
| Minimum order | 200 units per SKU, mixed cartons allowed |
| Lead time | 22 working days after artwork approval |
None of this is complicated. It is just written down, which is more than most buyers get before they wire a deposit.
Frequently asked
How long does production take?
Around 18 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.
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.
