3. Get your supplies from Chinese factories that have been checked out.
China is known as the best place in the world to make stainless steel tumblers.
Guangzhou, Zhaoqing, and Zhejiang are some of the cities that have advanced manufacturing clusters that can export a lot.
Some of the biggest manufacturers are:
Diller Bottle Factory (Guangdong) makes reusable bottles and vacuum-insulated tumblers.
Haers (Zhejiang) is a company that makes high-end thermal drinkware.
Fuguang (Anhui) is known for making a lot of things and having low prices.
Choosing a Chinese factory gives you better control over costs, shorter lead times, and full OEM flexibility.
4. Work with suppliers who only sell drinkware
In addition to regular factories, think about working with suppliers who only make drinkware and hydration products.
They usually have better designs, more advanced coating technology, and stricter quality control.
Brands of drinkware that people trust around the world:
Hydro Flask is based in the US and is known for its powder-coated tumblers.
Contigo makes travel mugs that don’t leak and smart lids.
Thermos is a well-known brand with a global supply network.
Working with specialized factories like Diller gives you the same quality benefits, but at a lower wholesale price.
5. Ask for product samples before placing big orders.
Always ask for samples to test before you agree to buy in bulk:
Quality of the material (304 or 316 stainless steel)
How well vacuum insulation works
Finishing the surface and adding color
How long will the logo engraving last?
Diller lets you see free samples and gives you pre-production samples to make sure your design meets your needs before it goes into mass production.
6. Put eco-friendly and reusable tumblers at the top of your list.
People today like stainless steel tumblers that are eco-friendly and can be used more than once instead of plastic ones that can only be used once.
When looking for wholesale tumblers, talk to your supplier about eco-friendly options like lids that don’t contain BPA, steel that can be recycled, and packaging that breaks down naturally.
Diller makes all of its tumblers out of food-safe stainless steel and coatings that are safe for the environment. These tumblers meet FDA and LFGB standards for export around the world.
