Client Challenge
The building materials supplier in Krakow was looking to expand its home fire safety product range to meet growing residential market demand in Poland. Previous suppliers had issues with:
- Inconsistent product quality between batches
- Missing AS 3786 / CB certification documentation
- Long lead times (60+ days) causing stock-outs
- Limited APP localization — English-only interface unsuitable for Poland consumers
Wanlin's Solution
Wanlin assigned a dedicated export account manager to the Krakow client and provided:
1. Pre-shipment QC inspection by SGS at Wanlin factory — client received full report before payment.
2. Complete AS 3786 / CB documentation package — accepted by Poland customs on first submission.
3. Customized packaging with Poland language instructions and local compliance marks.
4. 8-week delivery via sea freight (FCL) + DHL air for urgent replenishment orders.
5. English + local-language APP — reducing customer support burden for the Krakow client.

- Zero quality-related returns from end consumers in Poland
- 87% repeat purchase rate among end users who registered the APP
- Client expanded from 1 SKU to 4 Wanlin product lines
- Second order placed within 5 months — quantity increased by 67%
