Export Case Study: 1,370 pcs Door Window Magnetic Sensor (WL-DS150) Delivered to Dhaka — USD 128,000

Export Success: Door Window Magnetic Sensor (WL-DS150) — Dhaka, Bangladesh

This case study documents Wanlin Fire Protection's successful export project supplying Door Window Magnetic Sensor (WL-DS150) to a leading wholesale distributor in Dhaka, Bangladesh.

Project Overview

Client Challenge

The wholesale distributor in Dhaka was looking to expand its home fire safety product range to meet growing residential market demand in Bangladesh. Previous suppliers had issues with:

• Inconsistent product quality between batches
• Missing ISO 9001 / RoHS certification documentation
• Long lead times (60+ days) causing stock-outs
• Limited APP localization — English-only interface unsuitable for Bangladesh consumers

Wanlin's Solution

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

1. Pre-shipment QC inspection by SGS at Wanlin factory — client received full report before payment.
2. Complete ISO 9001 / RoHS documentation package — accepted by Bangladesh customs on first submission.
3. Customized packaging with Bangladesh 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 Dhaka client.

Results After 6 Months

• Zero quality-related returns from end consumers in Bangladesh
• 86% repeat purchase rate among end users who registered the APP
• Client expanded from 1 SKU to 7 Wanlin product lines
• Second order placed within 3 months — quantity increased by 72%
• Achieved ISO 9001 factory audit acceptance by Bangladesh 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 Bangladesh."
