If you’re in the vape industry—whether running a startup brand, scaling a distribution network, or managing a dispensary—the decision to buy empty carts in bulk from China is probably on your radar. It’s cost-effective, scalable, and frankly, almost an industry standard. But while it can open the door to serious profits, it can also bring headaches if you don’t know what to look out for.
At Cannvapes.com, we’ve been in this game for a while, and we’ve seen both sides of it. From buyers who end up with faulty, leaking carts by chasing the cheapest supplier, to those who elevate their business with sleek, branded cartridges that fly off the shelves—it’s all in the details.
So, before you hit that “Order Now” button on a 10,000-piece shipment, let’s walk through what really matters when you’re sourcing empty vape carts from China.
-
Material Quality: Don’t Compromise Here
The material your cart is made from will define your product’s feel, flavor, and safety. Here’s the deal:
- Glass or polycarbonate? Glass feels premium and doesn’t affect taste. Polycarbonate is cheaper but can leach flavors and degrade with certain oils.
- Ceramic or cotton wicks? Ceramic is the gold standard. It gives consistent heating and preserves the natural taste of your oil. Cotton burns too easily, especially with thicker extracts.
- Heavy metal safety? Huge one. In regulated markets, you’re required to sell carts that pass heavy metal testing. You don’t want to find out your carts fail after the shipment lands.
We always tell our partners: make material quality your first checkbox. It protects your brand and ensures every customer gets a great hit.
-
Coil Tech Makes or Breaks the Vape Experience
You could have the best oil in town, but if the coil inside your cart is trash, the user experience will be too.
Ask your supplier these:
- What type of coil do they use?
- What’s the resistance (typically 1.2–1.4 ohms is ideal)?
- Is the coil suitable for thick cannabis oils?
For extract-based brands, ceramic coils are the way to go. They heat evenly, don’t burn oil, and provide smoother draws. This is something we prioritize at Cannvapes.com because we know you can’t afford customer returns when you’re pushing product at scale.
-
Compatibility: It Has to Fit the Battery
Most vape batteries follow the 510 thread standard, but “standard” doesn’t always mean “compatible.” Especially with cheaper suppliers, slight differences in threading or contact pins can cause misfires or poor connections.
Double-check that your empty carts are:
- Fully 510-thread compatible
- Tested on multiple battery models
- Made with solid connection pins that won’t bend or break
At Cannvapes.com, all our carts go through compatibility testing before they ship. No surprises when they arrive—just plug, fill, and go.
-
Always Sample Before You Buy Bulk
This one’s non-negotiable. Never commit to a bulk order before testing the actual product.
Request samples of the carts you’re considering. Fill them with your own oil. Test how they hit. See if there’s leaking, clogging, weird taste, or breakage. It’s better to spend a few dollars on samples than thousands on a bad batch.
And when you sample from us? We can custom brand those samples for free. You’ll get a taste of both the hardware and your future product’s look.
-
Custom Branding: Your Cart, Your Identity
Here’s where smart vape businesses get ahead.
When you bulk order carts from China, don’t settle for generic, blank cartridges. Use the opportunity to make your brand stand out. Whether it’s your logo on the mouthpiece, engraved metal, or full custom packaging, branding sells.
At Cannvapes.com, we offer free custom branding on all bulk orders. No extra fees. No hidden costs. Just straight-up support to make your carts uniquely yours.
Want glossy black mouthpieces with gold logo printing? Done.
Need branded boxes with QR codes? We’ve got you.
Looking for tamper-proof packaging or child-resistant features? We’ll sort it out.
-
Filling Process: Make Sure It’s Smooth
Especially when you’re working with extract oils, the ease of filling your carts matters.
Ask about:
- Top-fill vs. bottom-fill: Top-fill is quicker and cleaner.
- Press-fit vs. screw-on mouthpieces: Press-fit can save you time during assembly.
- Filling capacity: Standard is 0.5ml and 1ml, but some custom sizes exist.
If you’re using a filling machine, you’ll want carts that don’t create air pockets or spill. The last thing you want is a messy fill line or inconsistent dosing.
-
Bulk Pricing vs. Bulk Quality: Find the Balance
We get it—when buying bulk, pricing matters. But don’t let low prices blind you. Super cheap usually means corners were cut somewhere, whether it’s:
- Cheaper metals that leach into oil
- Poor sealing that causes leaks
- Batch inconsistencies
When you’re building a brand, a few cents saved per cart isn’t worth damaging your reputation. Instead, go for a supplier like Cannvapes.com that balances competitive bulk pricing with top-tier quality control.
-
Understand MOQs, Lead Times, and Logistics
Chinese suppliers often have Minimum Order Quantities (MOQs). That’s fine—just make sure you:
- Know what the MOQ is (usually 1,000 pcs or more)
- Understand lead times (production + shipping)
- Ask about repeat order availability
You don’t want to run out of inventory mid-launch or wait six weeks for a reorder.
At Cannvapes.com, we offer fast fulfillment and transparent timelines. We’ll even give you updates during production, so you always know where things stand.
-
Don’t Overlook Custom Packaging
Branding doesn’t stop at the cart. The packaging matters just as much.
Here are a few things to consider:
- Custom printed boxes with your logo and strain info
- Tamper-evident seals for consumer trust
- Child-resistant options to meet regulations
- Eco-friendly materials for a greener image
Want to go retail-ready from day one? We can bundle custom carts + packaging into a full product line, all made to match your brand.
-

- Communicates clearly
