Sourcing electronics accessories from Shenzhen and Dongguan

Where are electronics accessories made in Guangdong?

In Shenzhen and Dongguan, both on the eastern side of the Pearl River Delta. This guide covers accessories: chargers, cables, power banks, earbuds and phone cases, bought as existing designs or with light changes such as your logo, colours or packaging. Custom electronics that need firmware development, new tooling or a certification programme of their own are outside what it covers.

Shenzhen. The city's action plan for its intelligent terminal industry cluster, issued in December 2022 for 2022–2025, covers smartphones, computers, tablets, VR and AR headsets, smart wearables, smart home appliances and other connected devices. It assigns districts different roles, naming Bao'an and Longhua as zones for "smart manufacturing plus pan-terminal" products. HKTDC Research's August 2026 profile of the city describes it as an important high-tech research and manufacturing base with many electronics firms.

Dongguan. HKTDC Research's August 2026 profile lists electronic information, and electrical machinery and equipment, among the city's five leading industries. The official profile of its Songshan Lake High-tech Zone calls the zone an important domestic base for smart terminals and electronic core components. On the national list of 45 advanced manufacturing clusters issued in 2022, Dongguan appears for intelligent mobile terminals and Shenzhen for new-generation information and communications technology. Dongguan is also a furniture base, covered in sourcing furniture from Foshan and Dongguan.

For electronics outside this guide's scope, such as small home appliances, is your product made in Guangdong? shows where each category is made, in Guangdong and elsewhere in China.

Should you buy from a factory, a trading company or Huaqiangbei?

It depends on whether you want stock or your own version. Huaqiangbei is an electronics trading district in Futian, Shenzhen. Its subdistrict office describes the businesses there as almost all small and micro firms and individual traders.

OEM (original equipment manufacturing) means the factory builds your design. ODM (original design manufacturing) means the factory's own design is adapted and sold under your brand. A trading company can also combine accessories with other categories, such as bags and leather goods, though each category brings its own rules. Whichever route you take, the checks in how to check a Chinese supplier before you pay still apply.

Not sure which kind of supplier you're dealing with? Factory or trading company? covers how to tell, and when a trader is fine. Finding suppliers in China compares markets, fairs, platforms and agents.

A caution on branded goods. If you buy from a market, be wary of anything that carries another company's brand, logo or a copied design. Ask for evidence that it is licensed, don't assume stock on display is genuine, and don't brief a factory to copy a design you don't own. If you are building your own brand or design, register it before you share it: the UK Intellectual Property Office's IP in China guidance explains how trade marks, designs and patents are registered there and notes China's "first to file" principle for patents, and the European Commission's China IP SME Helpdesk offers free first-line advice to small businesses in its programme countries.

What does your brief need for an electronics accessory?

The rules for your market, written into the specification. A factory can quote an accessory from a photo, but it cannot tell you whether that version can be sold where you are. Alongside the basics in how to write a sourcing brief, state:

• Where you will sell. Every market listed changes the radio, charging, labelling and battery requirements.
• Connector and charging. The port type, the charging protocol and the rated output. For in-scope devices sold in the EU, the port is USB-C.
• Battery. Chemistry, rated capacity and the watt-hour rating printed on the battery, which transport rules use.
• Radio. Whether the product uses Bluetooth or Wi-Fi, which radio module it uses, and whether that module is already approved in your markets.
• Connected features. Any app, account or default password. The UK's product security regime requires passwords to be unique to each product or set by the user.
• Test reports. Which reports exist, to which standard, for which model number, issued by which laboratory and in whose name.
• Markings, labels and packaging. The compliance marks, importer details and languages your market requires, and whether a charger goes in the box.
• Your own design and brand. Artwork, colours and logo files, and confirmation that nothing copies another brand.

How do samples and minimum order quantities work?

A minimum order quantity (MOQ) is the smallest order a supplier will accept. For accessories it usually rises with how much you change: a stock design in a stock colour needs less commitment from the factory than a custom colour, printed packaging or a new housing that needs its own mould.

Expect two kinds of sample. A stock sample, often available from a market or a trading company, shows the product family. A sample of your version shows what will actually be produced, and once approved it becomes the reference for the order. Ask the factory to confirm in writing that production will use the same battery cells, chipset and radio module as the approved sample, because a test report describes the product that was tested.

A sample power bank is still a lithium battery shipment, and the air-transport rules for lithium batteries apply to it as they do to a full order. Ask the supplier how it will be packed, declared and sent.

An independent inspection checks production against that approved reference; see inspections explained.

Samples from China covers requesting, paying for and judging samples for any product.

What drives the quote for electronics accessories?

These factors move the price. None of them can be priced without a specific product, quantity and destination:

• Battery cells: chemistry, capacity and where the cells come from.
• Chipset and charging protocol, particularly for fast chargers and power banks.
• Radio module: whether it is already approved for your markets or needs its own testing.
• Materials and finish: housing plastic, cable jacket, connectors and coatings.
• Tooling: a new shape needs a new mould; a stock shape does not.
• Testing and certification: which reports already exist, what must be done again for your market, and who pays for it.
• Packaging and labelling for each market, including manuals in the right languages.
• Order quantity and colour split.
• Freight: lithium batteries ship as dangerous goods, which narrows the options.
• Payment terms: the deposit, when the balance falls due and how it is paid; see paying a Chinese supplier safely.
• Incoterms: the international trade terms that set where the supplier's responsibility for cost and risk ends, such as FOB (free on board) or EXW (ex works).

MOQs and what drives a quote explains how each of these moves a price. To compare suppliers on the same basis, use how to compare supplier quotes. We don't publish prices because the quote depends on the scope above. If you want it scoped for your product, send a sourcing brief. We'll tell you if Guangdong isn't the right place for it.

What rules apply in your market?

The links below are official starting points, not advice on what applies to your product. Confirm the requirements for your exact product with the regulator or a qualified adviser before you order. For customs and general product safety in each market, start with import rules by country. If you also buy mains-powered lighting, sourcing lighting from Guzhen covers that category.

Electromagnetic compatibility (EMC) means a device neither causes nor suffers from electrical interference.

Four rules deserve a note because they change the product, not only the paperwork:

• EU common charger. The Commission's page says the rules have applied to phones, tablets, headphones, earbuds, portable speakers and other listed devices since 28 December 2024, and to laptops since 28 April 2026. USB-C is the common port, and consumers must be able to buy a device without a charger.
• Device security. The UK's PSTI regime has applied since 29 April 2024 and places duties on manufacturers, importers and distributors of consumer connectable products, including on default passwords. In the EU, the Radio Equipment Directive's cybersecurity requirements applied from August 2025 and, according to the Commission's page, are repealed from 11 December 2027, when the main obligations of the Cyber Resilience Act apply.
• Radio devices in the US. The FCC's page says radio-frequency devices must be authorised before they are marketed or imported, through either certification or a supplier's declaration of conformity.
• Lithium batteries by air. Each transport page above points to the ICAO Technical Instructions for dangerous goods by air. A power bank sample is a battery shipment too.

Everywhere else: start with your country's customs authority and its product-safety and telecoms regulators, and ask the supplier which of your market's test reports it already holds.

Which trade fair covers electronics accessories, and when?

Two of the four main options are in Hong Kong, not Guangdong. The October 2026 editions close before November; each organiser publishes its next dates on its own site, and the spring 2027 dates below are the ones published when checked.

For fairs across every category, see which trade fair for which product.
