China’s manufacturing base is not one factory — it is a network of regional clusters, each specialised in a category. Understanding where your product actually gets made changes how you source, price, and quality-check.
Geography
The Greater Bay Area cluster
The Pearl River Delta is China’s most concentrated manufacturing region, with a distinct specialty per city. Buyers who match product to cluster save money and reduce lead times.
- Shenzhen — electronics, IoT devices, wearables, product development.
- Dongguan — hardware, plastics, electromechanical assembly, OEM at volume.
- Guangzhou — consumer products, apparel, trading and re-export.
- Foshan — furniture, home products, ceramics, building materials.
- Zhongshan — lighting, small appliances, hardware accessories.
Factory types
OEM, ODM, OBM — what you’re actually buying
01
OEM (Original Equipment Manufacturer)
Factory produces to your design and specification. You own the IP. Best for buyers with their own product engineering and brand strategy.
02
ODM (Original Design Manufacturer)
Factory has a catalogue of existing designs; you rebrand and customise. Faster to launch, lower minimums, but IP is shared with everyone else who orders the same base design.
03
OBM (Original Brand Manufacturer)
Factory sells its own branded product. Rare in a sourcing context; usually seen in components and industrial equipment.
Relationships
What makes a factory relationship work
- Consistent order volume — factories prioritise buyers who reorder, not the largest one-off PO.
- Written specifications with tolerances — reduces the ‘we thought you meant…’ failure mode.
- Payment discipline — pay on the day you promised. This buys leverage when you need a rush order.
- Presence — visit the factory, or send an agent, at least once per year. Relationships fade without face time.
- Loyalty within reason — spread orders across 2–3 approved factories, not 20. Concentration builds trust; scatter destroys it.
Questions
Common questions
Should I visit the factory in person before ordering?
For orders above $10,000 or products with any safety component, yes. For low-value trial orders, a third-party audit report and a video walkthrough of the production line are usually enough.
Can I use one factory for multiple products?
Only if the products share process. Injection-moulded parts and printed apparel come from different factories with different equipment. Trying to force one supplier to cover both usually costs more, not less.
