Export Case Study: 2,153 pcs Door Window Magnetic Sensor (WL-DS150) Delivered to Berlin — USD 127,00

Export Success: Door Window Magnetic Sensor (WL-DS150) — Berlin, Germany

This case study documents Wanlin Fire Protection's successful export project supplying Door Window Magnetic Sensor (WL-DS150) to a leading online retail platform in Berlin, Germany.

Project Overview

Client Challenge

The online retail platform in Berlin was looking to expand its home fire safety product range to meet growing residential market demand in Germany. Previous suppliers had issues with:

• Inconsistent product quality between batches


• Missing CB / VdS certification documentation


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


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

Wanlin's Solution

Wanlin assigned a dedicated export account manager to the Berlin client and provided:

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

2. Complete CB / VdS documentation package — accepted by Germany customs on first submission.

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

4. 5-week delivery via sea freight (FCL) + DHL air for urgent replenishment orders.

5. English + local-language APP — reducing customer support burden for the Berlin client.

Results After 6 Months

• Zero quality-related returns from end consumers in Germany


• 86% repeat purchase rate among end users who registered the APP


• Client expanded from 1 SKU to 5 Wanlin product lines


• Second order placed within 3 months — quantity increased by 57%


• Achieved ISO 9001 factory audit acceptance by Germany 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 Germany."
