Reaching the Right Person Faster
For a quotation the fastest route is WhatsApp with the part number and quantity. For technical questions about compatibility or specifications, email is better because drawings and datasheets can travel with the message.
We answer during Shenzhen business hours, 09:00 to 19:00 China Standard Time, Monday to Saturday. Messages that arrive outside those hours are answered the next working morning, except for urgent production stops, which are handled whenever the phone is picked up.
If you are unsure which product line your request belongs to, send it anyway. Routing a message internally takes minutes. Asking you to resend it to another address costs a day.

Before You Write
What information do you need for a quotation?
Part number, quantity, and target date. If the part number is uncertain, send the function and package instead and we will identify candidates.
Do you reply at weekends?
Saturday yes, Sunday only for urgent messages. Orders placed on Sunday are processed on Monday morning.
Can you send samples before I place an order?
Yes, for stocked items. Sample freight is charged at cost and credited against the first production order.
Which languages can I write in?
English, Chinese in either script, Japanese, Korean, Vietnamese, and Thai. Replies come in the language you wrote in.
Is my enquiry kept confidential?
Yes. We do not share customer BOMs, drawings, or project names with other customers, and share with suppliers only what is needed to quote.
