How to source THC Vape leak test for AU
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.

Quality control, in plain terms
This page is for former smokers who want a working answer on specification, price and lead time before they commit a purchase order. We have written the detail down so nobody has to sit through a sales call to extract it.
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.
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.
Where the margin really sits
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.
Unit price breaks usually land at 240, 600 and 1200 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.
Choosing the core line
Factory capacity matters more than factory size. A line that can hold a tolerance across 5,000 units is worth more than a showroom that can produce 50,000 on paper. We qualify capacity by running a repeat order and measuring the drift.
When you compare suppliers for THC vape, ask for the last three production dates on the same SKU. If the answers are vague, the specification is not being held and the next batch will not match the sample you approved.
- Cartons drop-tested and pallet-counted for clean freight
- Consolidated or split shipping, quoted both ways
- Named account contact who has handled the product
- Document pack prepared per destination market
- Artwork proof plus physical dummy for custom packaging
- Reference sample retained from every batch
How orders move from factory to shelf
For repeat buyers we hold a shipping schedule rather than shipping on request. A fixed weekly cut-off means your reorder lands before the shelf empties instead of after.
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
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.
How long does production take?
Around 28 working days after artwork approval for stock configurations, plus transit. Custom runs add roughly a week for tooling and a physical dummy. We confirm the date in writing on the order acknowledgement.
What is the minimum order for THC vape?
Standard configurations start at 240 units per SKU, with mixed SKUs allowed inside the same carton. Custom colours, custom packaging or a private label run usually start at 600 units because of setup time on the line.
