With 40% of online consumers admitting they would share a photo of a unique package on social media, your shipping box has become your most powerful free marketing tool. For e-commerce businesses, the mailer box is no longer just a vessel for transport; it is a “mobile billboard” that builds trust and excitement before the product is even seen.
To streamline your sourcing, we compiled the Top 10 Mailer Box Manufacturers and Suppliers in China for 2026. These factories were chosen for their durable materials, eco-friendly options, and flexible low MOQs for growing brands.
Benefits of Importing Mailer Boxes from China
If you’re in the industry for custom mailer box orders, you might be wondering where to order. Should you get a local model or import one from China? Here are 4 benefits of importing mailer boxes from China:
Authentic Products
The first benefit is that counterfeits are much less common in China. When you buy a custom box from a local supplier, there’s always the risk that it’s fake. But sourcing directly means you always get verified, genuine products, protecting your business from unwanted drama and delays.
Save Money
You’ll save money. Custom mailer boxes from China are typically much cheaper than those from your local hardware factories.
Wider Selection to Choose
You’ll have a wider selection to choose from. Chinese mailer box manufacturers offer a wide variety of mailer box designs and materials, so you’re sure to find something that suits your taste.
Faster Production Turnaround
While shipping takes time, the manufacturing speed in China is often superior. Factories operate at a scale that allows for rapid production turnaround, meaning your custom order is ready to ship much faster than with many local manufacturers.

How to Choose the Right Mailer Box Manufacturer for Your Needs?
There are multiple things to consider when choosing a mailer box manufacturer. Do you want a metal mailer box or a plastic one? Do you want a traditional mailer box or something more modern? With hundreds of choices available, it can be challenging to know which is perfect. The most important thing is to figure out what your needs are.
Size and Type
First, consider the size and type of mailer box you need. Are you looking for a small locking mailer box for your condo or a large-capacity mailer box for your business? Once you’ve determined your needs, you can start narrowing down your choices.
Quality
Second, look at the quality of the mailer boxes on offer. Pay attention to the materials used and the craftsmanship involved. A well-made custom box should last for years with proper care, so it’s worth investing in quality.
Production Speed
In e-commerce, running out of packaging means stopping sales. Confirm their typical turnaround time for production and delivery to ensure they can restock you quickly before your inventory runs dry.
Material Strength
Your box needs to protect your product during a rough shipping journey. Ask about their corrugated cardboard grades (like E-flute or B-flute) to ensure they can provide a sturdy solution that prevents damage in transit.
