THC Vape sample testing protocol for the US market

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.

Price breaks and payment terms

THC Vape sits in a crowded price band, and the cheapest quote on the sheet is rarely the cheapest unit on your shelf. Everything below is built around reorder rate, defect rate and cash conversion rather than headline unit price.

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.

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.

Paperwork, labelling and market rules

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.

Artwork approval is a two stage process: a digital proof for text and layout, then a physical dummy for colour and finish. Skipping the dummy is the single most common cause of a reprint.

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.

Keeping the second shipment identical

The replacement policy is deliberately simple: report within seven days of delivery with photos and the batch code, and we replace or credit at the next shipment. We do not argue about a defect we can see in a photograph.

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.

  • Artwork proof plus physical dummy for custom packaging
  • Private label files archived for future rebrands
  • Cartons drop-tested and pallet-counted for clean freight
  • Specification locked in writing before production starts
  • Seven-day defect reporting with replace-or-credit
  • Reference sample retained from every batch

What a sensible opening order looks like

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.

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.

None of this is complicated. It is just written down, which is more than most buyers get before they wire a deposit.

Frequently asked

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.

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 is the minimum order for THC vape?

Standard configurations start at 300 units per SKU, with mixed SKUs allowed inside the same carton. Custom colours, custom packaging or a private label run usually start at 800 units because of setup time on the line.
