Export Success: Door Window Magnetic Sensor (WL-DS150) — S?o Paulo, Brazil

This case study documents Wanlin Fire Protection's successful export project supplying Door Window Magnetic Sensor (WL-DS150) to a leading home security installer in S?o Paulo, Brazil.

Project Overview

Client Challenge

The home security installer in S?o Paulo was looking to expand its home fire safety product range to meet growing residential market demand in Brazil. Previous suppliers had issues with:

• Inconsistent product quality between batches


• Missing CB / ETL certification documentation


• Long lead times (60+ days) causing stock-outs


• Limited APP localization — English-only interface unsuitable for Brazil consumers

Wanlin's Solution

Wanlin assigned a dedicated export account manager to the S?o Paulo client and provided:

1. Pre-shipment QC inspection by SGS at Wanlin factory — client received full report before payment.

2. Complete CB / ETL documentation package — accepted by Brazil customs on first submission.

3. Customized packaging with Brazil language instructions and local compliance marks.

4. 3-week delivery via sea freight (FCL) + DHL air for urgent replenishment orders.

5. English + local-language APP — reducing customer support burden for the S?o Paulo client.

Results After 6 Months

• Zero quality-related returns from end consumers in Brazil


• 88% repeat purchase rate among end users who registered the APP


• Client expanded from 1 SKU to 4 Wanlin product lines


• Second order placed within 3 months — quantity increased by 47%


• Achieved ISO 9001 factory audit acceptance by Brazil insurance partner

Client Testimonial

"Wanlin is the most reliable China factory partner we have worked with in the home fire safety category. Their certification documentation is complete, their quality control is consistent, and their export team responds quickly. We plan to grow our Wanlin SKUs to cover our entire fire safety product range in Brazil."
