Before you write
Three things people ask first.
Every inquiry is read by an engineer, not a ticket queue. Within 48 hours on working days you get a substantive reply — sizing recommendation, compliance scope and a sample plan. If your line-down situation is urgent, say so in the first sentence.
Yes. Engineering samples build in 2–4 weeks and ship with a full test report; sample quantities start from 2 units. Production MOQ is typically 10–50 units depending on model, so validation always comes before volume.
Yes. Your architecture, volumes and drawings are used only to quote and support your program — never shared, never published. An NDA is available on request, before you send anything sensitive.
Direct line
Skip the form. Email an engineer.
sales@ems-bbu.com reaches the same people who quote your project — answering from our Shenzhen operations with numbers and lead times, not brochures.
