THC Vape TPD red flags guide

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.

Compliance without the last-minute scramble

There is no shortage of suppliers quoting THC vape. The scarce thing is a supplier who will tell you which SKU to drop. We have been shipping THC vape products long enough to know that the honest answer is usually a shorter list, and that is the answer we give.

Age verification is not only a website problem. Retail packaging, shelf placement and staff scripting all carry compliance weight, and auditors increasingly ask for evidence of all three.

We keep batch codes traceable from carton to production date. When a market authority asks for traceability, a supplier who cannot produce it in an hour becomes a liability very quickly.

Where the margin really sits

Currency moves more than most buyers expect over a twelve month supply plan. We quote in USD and hold the price for 30 days from confirmation so your margin calculation is not guesswork.

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.

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.

The checks behind every shipment

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.

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.

  • Named account contact who has handled the product
  • Batch codes traceable from carton back to production date
  • Cartons drop-tested and pallet-counted for clean freight
  • Artwork proof plus physical dummy for custom packaging
  • Standing reorder schedule with a fixed cut-off
  • Mixed SKU cartons to spread first-order risk

Lead times, freight and landed cost

Documentation travels with the goods: commercial invoice, packing list, and the certificate set for your market. We send a scanned copy before dispatch so your broker can clear the file in advance.

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.

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

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 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.
