What to include in an inquiry
Include the product family, model where relevant, quantity, target market and required documents in the inquiry. For products with no specification page on this site, which is every product except HB-101 and URA-102, the inquiry should ask for the specification to be confirmed in writing. For COVID and other infectious disease products, the inquiry should also ask for availability and documentation for the destination market to be confirmed in writing.
Before payment, confirm availability, pricing, lead time, packing and documentation in writing. The company FAQ states that prices vary with supply and market factors, that international orders are subject to an ongoing minimum order requirement with no fixed figure published, that samples take about 7 days, and that mass production takes 20–30 days after deposit. Certificates are available upon request.
Before payment, confirm availability, pricing, lead time and documentation in writing. International orders are subject to an ongoing minimum order requirement (no fixed figure is published on this site); samples take about 7 days and mass production takes 20–30 days after deposit, as listed in the company FAQ.
What happens after an inquiry is sent
Send the inquiry to the published email address and request written confirmation of availability, pricing, lead time, packing and documentation for the named product. The response time and the form of the response depend on the inquiry, and this site does not promise a response time, because none is published in the company's own material.
That completeness matters most for products with no specification page on this site, where the written reply is the specification.
A note on the contact channels listed here
The contact channels listed on this page are the company's published public channels: the email address [email protected], the telephone number +86 571-81957782, the mobile number +86 18868123757, and the Yuhang address. No named individual contact is published here, because the company's own website does not publish a named contact person on its public pages. Inquiries go to the company's public inquiry channels, not to an individual.
Response expectations
This site does not promise a response time for inquiries, because none is published in the company's own material. If the inquiry is time-sensitive, state the deadline and ask whether a reply can be provided in time.
What a first inquiry usually names
A first inquiry to a diagnostic supplier usually names the product family and, where relevant, the model; the quantity or order type; the target market; and the documents needed for that market. Naming those four things in the first message gives the reader everything needed to route the inquiry to the right product information, rather than spending a first reply asking for the basics. That routing benefit is a matter of how inquiries are read, not a promise about any reply.
Market documents deserve a separate line in a first inquiry, because documentation varies by destination market and by product. An inquiry that lists the documents needed for its market, rather than asking generally about documentation, lets the reader check the specific documents against the specific product. The same applies to packing: an inquiry that states the packing or configuration it needs avoids a round of clarification about which configuration the inquiry refers to.
