Checklist for wholesale Vape Juice from Shenzhen

Customs, duty and the documents that move the carton

Age-verification and advertising rules follow the product into how you present it. Many markets treat claims about vape juice more strictly than the hardware itself, and auditors ask for evidence of compliant packaging and messaging. Keep health and comparative claims off the product page unless your legal side has signed them off. A buyers who stays conservative here avoids the expensive kind of attention.

If you sell into a market that requires specific certification, say so at quotation stage. A vape juice configuration that cannot legally enter the market you named should be flagged by the supplier before production, not by customs after shipping. A buyers who states the destination up front turns a potential seizure into a simple specification note.

Packaging that passes the market and the journey

Child-resistant closures are a specification, not an afterthought. Retrofitting one onto a finished vape juice design usually means a new mould and a delay. State the requirement at quotation so the run is built around it. A buyers who specifies early ships on time; one who adds late redesigns.

Protect the unit inside the carton as seriously as the carton itself. Internal dividers and correct fill volume prevent the transit leaks that generate returns. A buyers who specs the inner protection buys fewer complaints than one who trusts the outer box alone.

The quality checks that protect the order

Cosmetic grading should be written, not argued. Define what is acceptable and what is rejected before production, then apply it. A vape juice unit with a finish scuff inside tolerance is acceptable; one that makes a customer put it back is not. A your market buyer who gets this in the spec spares their staff the awkward conversation at the counter.

Battery safety is not a marketing sentence on vape juice; it is a test. Cells should be matched by capacity and internal resistance before assembly, and charging boards checked for cut-off voltage. Any unit that fails the cut-off should never reach packing. A your market buyer who requests the test record is buying safety, not a slogan.

Reading a vape juice quotation like a buyer

Read the lead-time line as a promise with a date, not a number. A vape juice quotation that says 'about three weeks' is not a quotation; it is a hope. Insist on a working-day figure from artwork approval, in writing, because that is the date your shelf depends on. A buyers who pins this down avoids the single most common cause of stockouts.

A vape juice quotation is only as good as the lines it does not show. The unit price is the bait; the landed cost is the meal. A proper quote lists unit price, packaging, freight, duty and an allowance for defects. When a your market buyer compares two suppliers, compare the five-line total, not the headline. The cheaper first line frequently becomes the dearer last one.

Red flags a first-time buyer should see early

The earliest red flag in vape juice sourcing is a supplier who cannot name a market they have shipped to. Genuine exporters name destinations because documents require it; a vague answer is a signal worth heeding. A your market buyer who notices this saves the deposit.

A third flag is a quotation that hides its lines. If a vape juice supplier bundles everything into one number and resists itemising by SKU, they are hiding which line carries the margin. A your market buyer who demands the breakdown exposes the gap before paying.

The compliance documents you cannot skip

Language on packaging is a frequent, avoidable failure. A vape juice label printed in the wrong language for your market is a non-compliant carton, full stop. Confirm the required languages at artwork proof and again at the dummy. A buyers who double-checks this small line avoids a large, late, expensive correction.

Advertising claims ride along with the product into how you present it, and most markets police them harder than the hardware. Keep cessation, health, and comparative claims off the vape juice page unless signed off legally. A your market buyer who stays conservative here avoids the costly kind of attention that no discount offsets.

Avoiding counterfeit in a bulk order

Counterfeit and grey vape juice enter bulk orders through the supply chain, not through the front door. The defence is verification at every step: a real factory, a held specification, and a sample compared to the production unit. A your market buyer who checks the chain sees the fake; one who trusts the photo meets it at the counter.

Price that is far below the market is rarely a bargain on vape juice; it is usually a signal. Genuine units have a floor set by cells, closure, and testing. A quote that breaks that floor deserves a harder look at what was removed to get there. A buyers who questions the impossible price avoids the impossible product.

The pitfalls worth avoiding, in one place

The cheapest protection on vape juice is a short checklist you actually run every order: verify the supplier, approve a sample, read the full quotation, confirm the documents, pin the lead date, and hold the specification for reorder. A your market buyer who does these six things sleeps through the quarter most others spend firefighting.

Most vape juice losses are not product failures; they are process failures — paying before verifying, approving without a sample, shipping without the documents. The product is usually fine; the discipline is what is missing. A buyers who builds the routine once stops paying for the same lesson repeatedly.

The checklist to run on every order

Pin the production and arrival dates in working days from artwork approval
Verify the supplier: licence, address, and a recent shipment reference in your region
Read the full quotation across all five cost lines, not just the unit price
Keep payment structured as deposit on spec, balance on shipment reference
Run the same checks on the second and third batches as on the first
Hold the approved specification on file for an identical reorder

Frequently asked

What should a vape juice quotation include?

Five lines: unit price, packaging, freight, duty, and an allowance for defects, plus the Incoterm, a price-validity window, the lead time in working days, and the defect remedy. Comparing only the unit price hides the real landed cost, and that is where most your market buyers lose margin.

How do I avoid counterfeit vape juice in a bulk order?

Verify the chain at every step: a real factory, a held specification, and a sample compared to the production unit. Check serial and batch codes against the shipping documents, and question any price that breaks the genuine market floor. Consistency across batches is the practical counterfeit test a your market buyer can run.

How long does vape juice production take?

About 25 working days after artwork approval for standard configurations, plus transit; custom runs add roughly a week for tooling and a physical dummy. Insist on the date in writing, because that is the date your shelf depends on, not a hopeful estimate from the supplier.

If you take one thing from this guide, take the reorder. The first shipment proves the sample; the second and third prove the supplier. Hold the specification, compare every repeat to the reference, and reward consistency with continuity. Do that on vape juice and the rest of the trade gets quietly easier, season after season, for a buyers who treats supply as a system.
