THC Vape sample testing protocol — a checklist

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.

How the price is actually built

We work with first-time 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.

Unit price breaks usually land at 300, 800 and 1600 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.

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.

Assortment planning without the guesswork

Most first-time buyers arrive with a spreadsheet and leave with too many SKUs. The fix is not a bigger catalogue, it is a narrower core. We normally propose three tiers: a volume line that carries the shelf, a step-up line that lifts basket value, and one trial SKU that tells you what to order next season.

We keep a short list of approved configurations for THC vape products. Anything outside that list is possible, but it becomes a custom run with a custom lead time, and we quote it as such rather than pretending everything is standard.

For first-time buyers, 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.

Quality control, in plain terms

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.

We photograph the packing station during production for volume orders. It is a small thing, but it settles most arguments about what was actually in the carton before it was sealed.

  • Batch codes traceable from carton back to production date
  • Named account contact who has handled the product
  • Cartons drop-tested and pallet-counted for clean freight
  • Reference sample retained from every batch
  • Specification locked in writing before production starts
  • Private label files archived for future rebrands

Getting the documents right

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.

If you sell into a market that requires child-resistant packaging, say so at quotation stage. Retrofitting a CR closure onto a finished bottle design usually means a new mould and a four week delay.

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

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.

How long does production take?

Around 30 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.

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.
