THC Vape sample testing protocol 101

This page is for private label sellers 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.

After-sales, replacements and reorders

If you are comparing three quotes for THC vape, compare the paperwork first. Test reports, artwork files, batch coding and the replacement clause tell you more about a supplier than the unit price on page one.

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.

Technical questions usually arrive at the worst possible moment, which is why we answer them on WhatsApp as well as email. A photo and a two line message resolves most issues faster than a ticket.

Where defects actually come from

Every batch is pulled from running production, not from a display shelf. We check draw resistance, airflow balance, charge behaviour, leak performance after a temperature shift, finish quality and carton integrity, and we keep the pull records against the order number.

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.

For private label sellers, the practical answer is usually a shorter range: two core lines, one step-up, one trial SKU. Everything else is inventory risk wearing a nice finish.

Price breaks and payment terms

The cheapest way to lower your cost per unit is usually to remove a SKU, not to negotiate a discount. Fewer lines means larger runs, fewer changeovers and a better price at the same quality.

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.

  • Document pack prepared per destination market
  • Cartons drop-tested and pallet-counted for clean freight
  • Artwork proof plus physical dummy for custom packaging
  • Private label files archived for future rebrands
  • Standing reorder schedule with a fixed cut-off
  • Reference sample retained from every batch

Shipping without surprises

For repeat buyers we hold a shipping schedule rather than shipping on request. A fixed weekly cut-off means your reorder lands before the shelf empties instead of after.

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.

If any of this is unclear, the fastest route is a message rather than a meeting. Send the market you sell into and the price band you work in, and you will get a specific answer instead of a brochure.

Frequently asked

Can we order samples before committing?

Yes. Sample orders are shipped by air express and the cost is credited against your first production order above 240 units. We would rather you handle the sample than approve a specification from a photograph.

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.
