Vape Coil commercial invoice FAQ

If you are comparing three quotes for vape coil, 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.

After-sales, replacements and reorders

This page is for online vape stores 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.

Reorders are the real test of a supplier. If the second shipment does not match the first, the relationship is over regardless of price, so we treat the reorder as the actual deliverable.

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.

Reading a quotation properly

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.

We publish a realistic band of 0.58 to 2.41 per unit for standard configurations at 240 units. Below that band you are buying a lighter specification; above it you are paying for finish, packaging or a smaller run.

For online vape stores, 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.

Where defects actually come from

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.

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.

  • Specification locked in writing before production starts
  • Named account contact who has handled the product
  • Batch codes traceable from carton back to production date
  • Artwork proof plus physical dummy for custom packaging
  • Private label files archived for future rebrands
  • Consolidated or split shipping, quoted both ways

Lead times, freight and landed cost

If you dropship, we can label cartons to your format and omit our documentation from the outer box. It is a small operational detail that decides whether your customer sees a supplier or a partner.

We ship from Shenzhen and Guangzhou: air express for samples and part loads, sea freight for volume. Typical production lead time is 15 working days after artwork approval, plus transit. We quote both routes so you can see the trade-off instead of guessing at it.

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 is the minimum order for vape coil?

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.

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 240 units. We would rather you handle the sample than approve a specification from a photograph.
