Electronic Components (ICs, PCBs and more)
Need a special chip or a custom circuit board? Shenzhen’s factories can make it happen faster than you’d believe.
For tiny parts like IC chips, resistors, capacitors, and printed circuit boards (PCBs), Shenzhen is the world’s go-to spot. You can find almost anything you need for a prototype, but you have to be careful about fakes.
When you source here, you’re plugging into the world’s electronics factory. This place makes over 90% of the world’s electronics, and the industry’s value grew by 11.8% in 2024. The global demand for semiconductors is huge—a $655.9 billion market in 2024—and Shenzhen is where you get direct access. We’ve seen factories turn around custom PCBs in just 24-48 hours. It’s perfect for testing new ideas. But there are traps. A common one is a supplier using a cheaper board material (low TG value), which means it can’t handle heat well and might fail. This is a classic risk in China electronics sourcing.
Why Shenzhen is Great for Components
- Everything is Close By: Factories are located near their suppliers, so there are no long waits for materials. The famous SEG Electronics Market is just the tip of the iceberg.
- Quick Prototypes: You can build and test a new product idea in days, not months. This is a huge win for small businesses.
- Good Prices: Lots of competition means you can find great prices on common parts like connectors, passive components, and standard chips.
What to Watch Out For
- Risk: Fake or used IC chips sold as brand new. It is necessary to find a reliable supplier.
- Our Tip: Always demand parts with codes you can trace and can even get them X-rayed to check. We know the trusted Shenzhen suppliers.
- Risk: Getting a batch of PCBs where the quality is all over the place.
- Our Tip: Do spot checks at the factory, comparing the boards to your design files to ensure everything is perfect.
Smartphone, Tablet, E-book Reader & Accessories
Want to launch your own brand of phones or tablets? Shenzhen’s factories have ready-made designs you can use right away.
Shenzhen is full of factories that can quickly make phones, tablets, and e-readers, and accessories for your brand. The advantage is speed, but you have to be careful about quality and make sure the devices will actually work for your customers.
There’s no doubt Shenzhen is the phone & accessories capital of the world. The secret here is something called gongban1, or "public models." These are the ones that are already designed and ready to go. Factories let you put your own logo on them (this is called OEM) and sell them as your own. It’s a super fast way to start. But be careful. We’ve seen clients get phones with bad IMEI numbers, which means they can get blocked by carriers or seized by customs. Also, to offer a cheap price, some factories cut corners on things you can’t see, like using a smaller battery or a slower processor.
Why Shenzhen is Great for Phones & Phones Accessories
- Launch Quickly: Use a gongban design to get your own branded phone to market in just a few weeks.
- All Parts Available: Everything from the screen and camera to the battery is made and sourced right here.
- Low Costs: Fierce competition keeps prices low for electronics wholesale China2.

- Risk: The phone looks like a famous brand, which could get you into legal trouble.
- Our Tip: Find good designers and can even help you register your own design in China to protect you.
PC Hardware & Gaming Gear & Peripherals
Building PCs or selling gaming accessories? Shenzhen is where you’ll find the best parts, deals, and custom options.
Shenzhen is packed with factories making keyboards, mice, webcams, motherboards, and more. The big win is getting awesome parts for cheap, but you need to check the quality carefully.
For anyone building computers or selling gaming gear, Shenzhen is the place to be. You can find factories for everything: mechanical keyboards4, RGB gaming mice, headsets, docking stations, and even PC cases. Because so many parts are made here, you can often find great deals on things like graphics cards (GPUs)5 and monitors when there’s an oversupply. Many suppliers will even let you test the parts before you buy a big batch. The best part is the customization. You can choose the exact switches for a keyboard or the ports for a docking station. But, the biggest risk is getting mixed quality. A supplier might send you a box of monitors with perfect A-grade screens mixed with flawed B-grade or C-grade screens. Another problem is when a product doesn’t work as advertised, like a USB-C hub6 that doesn’t support fast charging.
Why Shenzhen is Great for PC Gear
- Tons of Options: You’ll find a huge number of innovative factories for things like keyboards, mice, and other peripherals.
- Easy to Customize: You can work with a factory to design a product exactly how you want it.
- Everything is Made Nearby: The factories that make the plastic shells and do the assembly are all close, which makes things faster.
What to Watch Out For
- Risk: Getting a mix of good and bad quality parts in the same order.
- Our Tip: Push for strict batch testing and can check serial numbers to make sure you’re getting what you paid for. This is key for China electronics quality control.
- Risk: The software or drivers for the product are buggy and unreliable.
- Our Tip: Make sure the supplier agrees to provide software updates and support after you’ve bought the product.
Smart Home & Wearable Tech & AI toy
Want to sell the latest smart gadgets? Shenzhen’s factories are already making them, giving you a head start on the competition.
Shenzhen is the best place to source smart gadgets like fitness trackers, smartwatches, AI toys and smart plugs. You can get new tech fast, but you must check that the products are safe and the software works well.
If you want to see the future of tech, just walk around Shenzhen. The product cycle is so fast that new features, like noise-canceling for wireless earbuds, show up here just weeks after they’re announced. With the rapid development of AI technology, the application of AI in these electronic manufacturing fields is getting deeper and deeper.AI earphones like Doubao and AI educational toys that perfectly combine software and hardware are mainly manufactured in Shenzhen.The market for these gadgets is huge, with China’s consumer electronics expected to reach $347.7 billion by 2030. Thanks to platforms like Tuya, any factory can easily make a "smart" version of their product. This means there are tons of new things to sell, from smart curtains to smart coffee makers to AI smart glasses, watches. But this speed has a dark side. For example, you should be very careful about battery safety, cutting corners on materials. Another big risk is fake safety certificates. A supplier might say their product is CE or FCC certified, but the papers are often fake.
Why Shenzhen is Great for Smart Gadgets
- Be First to Market: Get your hands on new gadgets months before they are available anywhere else.
- Works with Everything: Most products are designed to easily connect with Amazon Alexa or Google Assistant.
- Endless New Products: Almost every household item has a "smart" version here, giving you tons of new things to sell.
What to Watch Out For

- Risk: The company stops updating the app, making your smart device dumb.
- Our Tip: Check out the supplier’s software team to make sure they’ll be around to support the product long-term.
Shenzhen’s Car & EV Electronics & Spare Parts
Sourcing electronics for cars, like dashcams or EV chargers? Shenzhen’s factories are becoming experts in this area.
Shenzhen is a great place to source automotive accessories. The factories here can make them quickly, but you need to ensure they are truly "car-grade" and not just consumer electronics in a different box.
Home to electric car giants like BYD, Shenzhen has a very strong supply chain for car electronics. This means new tech, like better sensors for dashcams or faster EV charging, gets turned into products very quickly. Many factories here know how to meet car-specific quality standards like AEC-Q and E-mark. We’ve ever helped clients source everything from battery management systems (BMS) for electric bikes to full-blown EV charging stations. A big problem, though, is that many products are sold as "automotive-grade" when they’re not. They are just regular electronics that haven’t been tested to withstand the heat and vibrations of being in a car. They will fail sooner. Also, for anything high-voltage like an EV charger, you absolutely need a real safety certificate from a body like TÜV or UL.
Why Shenzhen is Great for Car Electronics
- Built on a Strong Foundation: The supply chain is strong thanks to the big EV companies based here.
- Uses the Latest Tech: New sensors and charging tech are put into products almost immediately.
- Experience with Standards: Many factories know how to make products that meet tough automotive rules.
What to Watch Out For
- Risk: Getting a "car" product that’s really just a fragile consumer gadget.
- Our Tip: Check the list of internal parts to make sure they are real automotive-grade components and verify all safety claims.
- Risk: The product’s software doesn’t work with the car’s computer system.
- Our Tip: Test for this and make sure the supplier has a plan for software updates.
Connectors, Cables & Mechanical Parts
Every electronic product needs wires, plugs, and a case. Shenzhen’s technology research and development and precision are very high.
For things like USB cables, internal wires, and plastic or metal shells, Shenzhen’s factories offer amazing speed and prices. Just be sure to check that they don’t use cheap materials.
This is one of the best-kept secrets of electronics manufacturing China7. If your product needs a custom cable or a plastic case, you can get it made here faster and cheaper than anywhere else. We’re talking 30-50% cheaper than in Europe or America. You can get a prototype of a custom USB-C cable8 the same day you order it. Need a mold for a new plastic part? It can be ready in weeks. The factories that make the connectors, the wires, and the plastic shells are all in the same area, so they work together seamlessly. But you have to watch the details. A common trick is using less gold on the connector pins, which makes them fail over time. Another is using cheap aluminum wire covered in copper instead of pure copper, which is bad for charging and data speed. Fake UL safety marks are also a huge problem.
Why Shenzhen is Great for These Parts
- Get Anything Custom-Made: No matter what kind of weird cable or case you need, a factory here can make it for you.
- Huge Selection: You can find every type of connector imaginable, from simple ones to high-speed industrial ones.
- Everything Works Together: The mold makers, plastic injection factories9, and assembly workshops are all neighbors, which speeds things up.
What to Watch Out For
- Risk: Flimsy connectors because the gold plating is too thin.
- Our Tip: Arrange for tests to check the plating thickness and make sure the materials are what they’re supposed to be.
- Risk: Fake safety certificates that could get you in trouble.
- Our Tip: Check every certificate with the organization that issued it, so you know it’s real.
Industrial & IoT Modules
Building a smart device? Shenzhen is where you’ll find the electronic "brains" and "senses" to make it work.
Shenzhen is the best place to source the core components for IoT devices, like wireless modules and sensors. The flexibility is great, but you need to be very careful about software security.
For anyone making smart gadgets for homes, farms, or factories, the factories in Shenzhen are a goldmine. This is where you find the building blocks of the "Internet of Things" (IoT): microcontrollers (MCUs), sensors, and wireless modules for WiFi, Bluetooth, LoRa, and 5G. The best part is that many of these factories will write custom software (firmware) for your specific product, even if you only order a small number. This is amazing for startups. As China’s high-tech exports grow, which hit $825.2 billion in 2024, these little modules are getting more and more powerful. But the risks are technical. We always warn about "backdoors" in the software that could let hackers in. Also, getting the radio approved for sale in other countries (like getting FCC approval for the US) is tricky. A failed test can stop your launch cold.
Why Shenzhen is Great for IoT Modules
- Custom Software: Get custom firmware for your product without having to order thousands of units.
- Expert Factories: Lots of factories here are experts in IoT and know exactly what they’re doing.
- All-in-One Sourcing: You can easily find all the different sensors and modules you need for your device in one place.
What to Watch Out For
- Risk: Security holes in the software that could let hackers take control of your device.
- Our Tip: Set up contracts that require secure coding and can connect you with experts to check the code for you.
- Risk: The wireless radio fails safety or compliance tests in your country.
- Our Tip: Get all the test reports from the factory and recommend doing a pre-test at an independent lab before you order a big batch.
Customized Security Cameras & Systems
Need security cameras or access control systems? Shenzhen’s factories can make exactly what you need at a great price.
Shenzhen is a world leader in making security gear. You can get custom designs made quickly, but you must be sure the products are secure and don’t have any hidden privacy issues.
For anyone installing security systems, Shenzhen offers a huge advantage. You can find great deals on complete systems, including CCTV cameras and access control panels, that all work together easily. The best part is how fast you can get custom designs. If you need a camera with a special case to match a building’s design, a factory can make it for you in a few weeks. This is perfect for big projects. To avoid the risk is to need a safe server.
Why Shenzhen is Great for Security Gear
- Great Value: Get complete, high-quality security systems for a very competitive price.
- Fast Customization: Quickly get custom-designed housings or features for your projects.
- Mature Tech: The technology for cameras and sensors is very advanced and reliable.
What to Watch Out For
- Risk: Hidden software that spies on you or sends your data to unknown places.
- Our Tip: Buy from factories that use trusted, "white-listed" computer chips and are transparent about their software.
- Risk: Accidentally buying a product with parts that are banned in your country (like under NDAA in the US).
- Our Tip: Demand and check statements from the factory to prove their products are compliant and safe for your market.
LEDs & Optics
Working on a lighting project? Shenzhen’s factories offer the best prices on LEDs and lenses, but you need to test their claims.
For any product that involves light, like lamps, displays, or signs, Shenzhen is the place to source. The prices are low, but you have to verify that the quality and brightness are as good as the supplier claims.
When it comes to LEDs, Shenzhen is a world leader in price. You can often get LEDs that are 30-50% cheaper here than in other parts of China. Many of the better suppliers have special equipment (called an integrating sphere) that lets you test the brightness and color of the LEDs right there in the factory. This is a great way to check quality on the spot. You can find everything here, from the tiny LED chips themselves to the custom plastic lenses you need to direct the light. The biggest risk is that suppliers will exaggerate how good their LEDs are. They might claim a super high brightness that the LED can only maintain for a few minutes before it gets too hot and starts to fade. Another problem is bad "binning," which is when the LEDs in your order all have slightly different shades of white, making your final product look cheap and inconsistent.
Why Shenzhen is Great for LEDs
- Amazing Prices: Get more brightness for your buck, with prices 30-50% lower than elsewhere.
- Test Before You Buy: Good suppliers will have equipment that lets you test the lights right away.
- Complete Packages: You can source the LED, the lens, and the power supply all from the same area.
What to Watch Out For
- Risk: The LEDs are not as bright as promised or they dim very quickly.
- Our Tip: Demand to see the official LM-80 test report, which proves how long the LED will stay bright.
- Risk: The color of the light is inconsistent across your order.
- Our Tip: Specify the exact color you want in the contract and do spot checks to make sure they all match.
Drones & Imaging Tech
Sourcing drones or high-tech cameras? Shenzhen is home to the world’s top experts and suppliers.
As the home of DJI, Shenzhen is the best place in the world to develop a drone or camera product. The speed is incredible, but you have to navigate complex export rules.
Shenzhen is the center of the drone universe, period. Being here means you’re right next to the world’s best engineers and suppliers for drones, gimbals, and high-tech cameras. This can cut the time it takes to develop a new prototype down to just a couple of weeks. It’s a huge advantage for anyone in filmmaking, agriculture, or inspection services. With China’s total foreign trade hitting a record 43.85 trillion yuan in 2024, exporting high-tech products like drones is a big deal. But this is also where the biggest risk lies. Advanced drones and thermal cameras are often considered "dual-use" items (meaning they could have military applications) and have very strict export rules. Another trap is "locked" firmware. A supplier might prevent you from writing your own software for the drone unless you specifically negotiate for an unlocked version.
Why Shenzhen is Great for Drones
- Access to the Best: You’re right next to the talent and suppliers that support the world’s biggest drone company.
- Incredibly Fast Prototyping: Go from an idea to a flying prototype in as little as two weeks.
- Expert Optical Suppliers: Find experts to make custom lenses, sensors, and stabilizers for your camera.
What to Watch Out For
- Risk: Your product gets stuck in customs because of export control laws.
- Our Tip: Check the product’s classification number (ECCN) to make sure it can be legally exported.
- Risk: The drone’s software is locked, so you can’t customize it.
- Our Tip: Negotiate a contract that gives you an unlocked version with the tools you need to write your own code.
Electronic Repair Part or Tool
Running a repair shop or refurbishing electronics? Shenzhen is your ultimate treasure chest for parts and tools.
Shenzhen is a one-stop-shop for the global electronics repair industry. You can find anything, but you have to be vigilant about the quality and grade of the parts you buy.
For any business that repairs electronics, Shenzhen is paradise. The Huaqiangbei electronics markets and the warehouses around them are filled with every part you can imagine, from a specific tiny screw for a laptop to a professional hot-air station for fixing circuit boards. You can find replacement screens, batteries, charging ports, and flex cables for almost any phone or tablet ever made. The logistics are super fast, with trucks running to Hong Kong every hour, so you can get parts to your repair centers around the world quickly. The business here is huge, with the Huaqiangbei area alone doing over 200 billion yuan ($27.78 billion) in sales a year. The biggest risk is getting mixed-quality parts. For example, a supplier might sell you a batch of batteries that includes both good Grade-A cells and cheap, low-capacity Grade-B cells all mixed together.
Why Shenzhen is Great for Repair Parts
- Find Anything and Everything: It’s a true one-stop-shop for repair parts and tools.
- Super Fast Shipping: Get parts out of China and on their way to you very quickly.
