Before you message us
Replies within one business day with a consultation or supplier verification plan. Fee detail is on the commission page; the process behind the quote is on how it works.
How fast will you reply?
Within one business day — usually within 12 hours on working days (Mon–Fri 9AM–6PM, Sat 9AM–4PM China time). WhatsApp at +86 186 0300 7346 is fastest; email is info@yinhansourcing.com.
What should I include in my message?
A product link, photo or drawings, target quantity and your deadline. That is enough for a consultation and itemized factory shortlist; packaging, compliance and shipping details can follow on the call.
Will you share my product idea?
Never with third parties. Supplier RFQs describe specs without exposing your brand, sales channels or pricing, and NDAs are available on request before you share drawings.
Can we talk before committing to anything?
Yes — the first consultation is free with no obligation, by video call, WhatsApp or email. You get a verification plan or itemized quote to judge before any fee is agreed.
