THC Vape spare kit: with COA
We work with dropshippers 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.

Where defects actually come from
Buyers come to us for THC vape after a bad quarter: dead stock on one side, empty shelves on the other. The cause is usually the same, an assortment built from a catalogue instead of from sell-through data. This page explains how we rebuild that balance for dropshippers.
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.
12 separate checks run before a carton is sealed: electrical, mechanical, leak, finish and packaging. Anything outside tolerance is quarantined the same day and reported to you, rather than shipped with a hope and a discount.
Building an assortment that actually turns
A practical starting order for dropshippers is 200 units across two or three SKUs, not 200 units of one. That spreads the risk, gives your staff something to compare, and still hits the first price break.
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.
After-sales, replacements and reorders
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.
Technical questions usually arrive at the worst possible moment, which is why we answer them on WhatsApp as well as email. A photo and a two line message resolves most issues faster than a ticket.
- Named account contact who has handled the product
- Seven-day defect reporting with replace-or-credit
- Batch codes traceable from carton back to production date
- Reference sample retained from every batch
- Specification locked in writing before production starts
- Mixed SKU cartons to spread first-order risk
Unit price versus landed cost
Custom printing raises the unit price and lowers the marketing cost. For dropshippers the break-even is usually reached on the second or third repeat order, not the first, so we quote both branded and neutral options.
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.

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.
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.
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 200 units. We would rather you handle the sample than approve a specification from a photograph.
What is the minimum order for THC vape?
Standard configurations start at 200 units per SKU, with mixed SKUs allowed inside the same carton. Custom colours, custom packaging or a private label run usually start at 500 units because of setup time on the line.
