Where Shenzhen sits in electronics

Shenzhen is a secondary cluster rather than the biggest one. It holds 13% of the electronics suppliers in our directory, so buyers normally price this city against two or three larger clusters before committing — the quotes are often keener for that reason.

City	Factories	Share of industry
Shenzhen	40	13%
Wenzhou	25	8%
Dongguan	16	5%
Guangzhou	15	5%
Shanghai	14	5%
Ningbo	12	4%
Suzhou	9	3%
Yueqing	9	3%

Before you request a quote

Electronics suppliers in Shenzhen and Dongguan cover everything from PCB assembly to finished consumer devices. ISO 9001 is table stakes; ask separately about IPC-A-610 class and component sourcing policy.

What to put in the RFQ

Most price gaps between Shenzhen suppliers come from the brief, not from the factory. Include these and the comparison gets honest:

• Drawing or spec sheet, with tolerances and the critical dimensions marked.
• Material grade and any substitution you would accept.
• Surface finish, colour reference and packaging method.
• Sample quantity, trial order quantity and expected annual volume.
• Certification the product must carry, and who pays for the testing.
• Trade term and destination port, so freight is priced the same way.
• Required delivery date, plus how much slip you can absorb.
• Inspection method: who inspects, at what stage, and against which standard.

How to check a supplier before you pay a deposit

Company names in a directory tell you who exists; they do not tell you who can actually run your order. In Shenzhen the checks that catch most problems are the boring ones: the business licence name matches the factory address on the contract, a live video walk-through shows the machines the process needs rather than a showroom, and the test report is issued for the material you specified rather than a generic certificate. Put the inspection stage, the acceptance standard and the payment split into the contract — a 30/70 split against a pre-shipment inspection is normal, full payment up front is not.
