Evidence-backed sourcing regions
Each location below is classified by the role supported by the cited evidence. The classification does not verify an individual supplier.
Guangdong, China
Longhua District / wider Shenzhen supply chain, Shenzhen
Sourcing notes
Use Shenzhen as a product-development lead, then inspect where molding, coating, magnet assembly, printing and packing occur.
Why this location is included
A current official case provides category-specific evidence, but independent region-wide cluster evidence remains incomplete. [1]
What buyers should verify
- Molding and finishing addresses
- Model fit and CAD control
- Material and magnet tests
- Mold and design ownership
Buyer risks
- One official case does not prove a citywide cluster
- Design office and molding factory may be different companies
Hunan, China
Xidu High-tech Zone, Hengyang County, Hengyang
Sourcing notes
The evidence covers an operating production site, not a broad TPU or silicone case ecosystem.
Why this location is included
A 2024 municipal source documents operating tempered-glass protector production at the precise site, but cluster-scale evidence is limited. [2]
What buyers should verify
- Glass source and thickness
- Edge finishing and coating
- Optical and fit tests
- Scratch, impact and packaging tests
Buyer risks
- Single-site evidence
- Promotional scale claims are not independently verified
Why this region matters
A current Shenzhen government case documents phone-case design and production tied to the city's consumer-electronics supply chain, but it is one case rather than cluster-wide proof. [1]
Hengyang government records an operating tempered-glass phone-protector production site in Xidu High-tech Zone, but does not prove a broad case-manufacturing cluster. [2]
What buyers can source here
- TPU, PC, silicone, leather and hybrid phone cases
- Screen and lens protectors
- Passive phone stands and holders
- Decorative passive phone accessories
- Custom molds, printing and packaging after factory verification
Manufacturing cluster vs wholesale market
Manufacturing cluster
Shenzhen is a design/supply-chain lead; Xidu is a documented screen-protector production site. Both remain Partially Verified.
Wholesale or trading market
Huaqiangbei and Guangzhou markets were removed because market activity is not proof of case manufacturing.
Regional sourcing model
Passive protective and mechanical products only; powered accessories use Mobile Accessories.
Best for / less suitable for
Best for
- Phone-case private-label projects
- Screen and lens protector buyers
- Buyers able to conduct model-by-model fit tests
- Programs with controlled artwork and mold ownership
Less suitable for
- Chargers, cables or power banks
- Wireless chargers and active mounts
- Buyers without exact device models
- Official-certification claims without issuer evidence
How to verify that a supplier is connected to this cluster
- Provide exact device model, CAD or approved dimensions and test camera, port and button alignment on real devices.
- Confirm TPU, PC, silicone or leather composition, hardness, odor, restricted substances and yellowing resistance.
- Define drop-test method, sample size and acceptance criteria instead of accepting a generic drop-proof claim.
- For magnetic cases, measure magnet strength and alignment; 'MagSafe compatible' does not mean officially certified.
- Confirm mold ownership, coating, print durability, packaging and intellectual-property clearance before mass production.
Buyer risks and caveats
- Fast device-model changes can create fit and inventory risk.
- Material, magnet and drop-protection claims can be vague or untested.
- Artwork, brand and industrial-design rights may be infringed.
- A market seller or design brand may outsource all molding and printing.

Longhua, Shenzhen
A Shenzhen government case documented phone-case design and production using the local electronics supply chain. It supports a sourcing lead, not a citywide cluster claim. [1]
Xidu High-tech Zone, Hengyang County
A tempered-glass protector facility was reported in operation after new production lines were installed. Buyers should verify current capacity and the exact production entity. [2]
