THC Vape sample testing protocol — a checklist

Batch consistency and why it matters

If you are comparing three quotes for THC vape, compare the paperwork first. Test reports, artwork files, batch coding and the replacement clause tell you more about a supplier than the unit price on page one.

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.

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.

How we structure a first order

We source THC vape products from a small group of factories we have worked with for years. That means a specification can be held across repeat orders instead of being re-qualified from scratch every quarter. Consistency is a boring selling point and it is also the entire game.

A practical starting order for dropshippers is 240 units across two or three SKUs, not 240 units of one. That spreads the risk, gives your staff something to compare, and still hits the first price break.

Transit, consolidation and timing

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.

We ship from Shenzhen and Guangzhou: air express for samples and part loads, sea freight for volume. Typical production lead time is 18 working days after artwork approval, plus transit. We quote both routes so you can see the trade-off instead of guessing at it.

• Artwork proof plus physical dummy for custom packaging
• Document pack prepared per destination market
• Named account contact who has handled the product
• Reference sample retained from every batch
• Seven-day defect reporting with replace-or-credit
• Mixed SKU cartons to spread first-order risk

Compliance without the last-minute scramble

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.

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.

Specification summary

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.
