THC Vape quality control steps checklist

Ordering THC vape is not difficult. Ordering THC vape that sell through without a return queue behind them is the part most buyers underestimate, and it is where we spend our time. We supply dropshippers in European and North American markets with core lines that turn over predictably, and we keep the specification list short enough for your team to actually manage.

Assortment planning without the guesswork

Buyers come to us for THC vape after a bad quarter: dead stock on one side, empty shelves on the other. The cause is usually the same, an assortment built from a catalogue instead of from sell-through data. This page explains how we rebuild that balance for dropshippers.

The first question we ask is not what you want to spend. It is what your customer already buys. Answer that and the THC vape list writes itself; skip it and you end up with a pallet of stock that photographs well and sells badly.

Most dropshippers 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.

How orders move from factory to shelf

We ship from Shenzhen and Guangzhou: air express for samples and part loads, sea freight for volume. Typical production lead time is 22 working days after artwork approval, plus transit. We quote both routes so you can see the trade-off instead of guessing at it.

Freight on THC vape products is driven by volume more than weight. Cartons are designed to hit a clean pallet count, which is why a slightly denser pack can cut your landed cost by more than a discount on the unit price ever would.

For dropshippers, 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.

The reorder is the real test

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.

Returns are handled as data, not as complaints. Every reported failure is logged by mode and by batch, and the pattern is reviewed monthly with the factory.

  • Seven-day defect reporting with replace-or-credit
  • Specification locked in writing before production starts
  • Reference sample retained from every batch
  • Consolidated or split shipping, quoted both ways
  • Batch codes traceable from carton back to production date
  • Mixed SKU cartons to spread first-order risk

Where the margin really sits

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.

Unit price breaks usually land at 120, 500 and 1000 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.

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.

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.

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.
