Sourcing Starter Vape Kit: commercial invoice playbook

Where defects actually come from

We work with B2B 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.

Leak complaints almost always trace back to one of three things: an over-torqued centre post, a seal that sat in a hot container, or a fill volume pushed past the design limit. We cap fill volume slightly below maximum for exactly that reason.

Cosmetic grading is written down, not argued about. Minor scuffs inside the tolerance band are accepted; anything that would make a customer put the unit back on the shelf is rejected. Your staff should never have to explain a finish defect to a paying customer.

Paperwork, labelling and market rules

Advertising rules are stricter than product rules in most markets. Claims about cessation, health or comparative performance should stay off packaging and off your product pages unless your legal team has signed them off.

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.

Support that answers the question

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.

We keep the specification sheet for every order on file. Two years later, when a customer asks whether a pod is compatible, the answer is a lookup rather than a guess.

• Document pack prepared per destination market
• Mixed SKU cartons to spread first-order risk
• Seven-day defect reporting with replace-or-credit
• Reference sample retained from every batch
• Batch codes traceable from carton back to production date
• Private label files archived for future rebrands

Unit price versus landed cost

Unit price breaks usually land at 60, 240 and 480 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.

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.

Specification summary

The detail above is what we hold ourselves to on every shipment, including the small ones. It is also the list we will walk through with you before the first order.
