Client Challenge
The wholesale distributor in Johannesburg was looking to expand its home fire safety product range to meet growing residential market demand in South Africa. Previous suppliers had issues with:
- Inconsistent product quality between batches
- Missing EN14604 / ISO 9001 certification documentation
- Long lead times (60+ days) causing stock-outs
- Limited APP localization — English-only interface unsuitable for South Africa consumers
Wanlin's Solution
Wanlin assigned a dedicated export account manager to the Johannesburg client and provided:
1. Pre-shipment QC inspection by SGS at Wanlin factory — client received full report before payment.
2. Complete EN14604 / ISO 9001 documentation package — accepted by South Africa customs on first submission.
3. Customized packaging with South Africa language instructions and local compliance marks.
4. 4-week delivery via sea freight (FCL) + DHL air for urgent replenishment orders.
5. English + local-language APP — reducing customer support burden for the Johannesburg client.
Results After 6 Months
- Zero quality-related returns from end consumers in South Africa
- 93% repeat purchase rate among end users who registered the APP
- Client expanded from 1 SKU to 6 Wanlin product lines
- Second order placed within 3 months — quantity increased by 44%
- Achieved ISO 9001 factory audit acceptance by South Africa insurance partner
