THC Vape CE and RoHS evidence 101

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 private label sellers.

Turning shelf space into repeat visits

We work with private label sellers 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.

Seasonality in THC vape products is real but smaller than most buyers assume. The bigger swing comes from restocking discipline, not from calendar events.

Staff knowledge converts better than any poster. If your team can explain the difference between two coils in one sentence, the step-up SKU sells itself.

Shipping without surprises

Transit times move with the season. Book space early for Q4 and around Chinese New Year, when factory output pauses for two to three weeks and freight rates tighten at the same time.

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 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.

Unit price versus landed cost

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.

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.

  • Artwork proof plus physical dummy for custom packaging
  • Document pack prepared per destination market
  • Mixed SKU cartons to spread first-order risk
  • Reference sample retained from every batch
  • Seven-day defect reporting with replace-or-credit
  • Batch codes traceable from carton back to production date

Quality control, in plain terms

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.

A 0.5 percent defect rate sounds excellent until it lands on a 600 unit order and you are handling three returns in a week. We quote realistic rates per category and we credit in advance for the known failure modes.

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.

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.

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 50 units. We would rather you handle the sample than approve a specification from a photograph.
