That is 03:10 – 12:00 in Berlin and 21:10 – 06:00 the previous evening in New York, while those cities are on summer time. If you write at the end of your working day, the reply is usually waiting when you open your laptop.
English and Chinese. Write in either.
Two addresses, both real, both in Gushu, Xixiang Street, Bao'an District, Shenzhen. The office takes meetings; the factory is the one you should ask to see.

The sign in the lobby reads SUNTC. It is the same company — an older abbreviation of the same English trade name that gives us the domain sunntc.com.

The mould shop, the PCBA production workshop, the assembly line and the inspection bench. Visits take three working days' notice; a video walk-through takes one.
Five lines and you get a real quotation instead of a request for more information. This is the whole difference between a two-email exchange and a two-week one.
A model number from this catalogue, or a photograph of the shape you want. If it is already tooled, there is no tooling bill.
Price bands move with volume. A price without a quantity is a guess, and it will be the wrong one.
It decides the certification set, the packing and the freight.
Tell us the number you need to hit. We will say whether it is reachable, and which specification gets you there.
Printed logo, laser etch, or plain. And whether you need your own box.
You will get back an ex-works price, a lead time and a packing size. If we cannot do it, you will be told that instead — that answer also arrives within one working day.
T/T bank transfer and Western Union are accepted on every model in the catalogue; L/C is accepted on some orders — ask when you request the quotation. Prices are quoted ex-works Shenzhen unless you ask for another term.
The deposit split is stated on your proforma invoice, before you commit to anything.
Our bank details are never published on this website and never sent from a free email address. If you receive payment instructions that do not come from lyn@sunntc.com, telephone us on +86 755 2907 4277 before you send anything.
Supplier-impersonation fraud targets this trade specifically, and it usually arrives as a friendly email about a 'new bank account'. One phone call defeats it.
Three working days' notice and Miss Lyn will walk you through the mould rack, the PCBA production workshop, the assembly line, the inspection bench and the packing tables. Your own auditor or a third-party body — SGS, Bureau Veritas, TÜV — is welcome on the same terms. The one thing nobody is shown is another customer's tooling or artwork.
Everything marked required is something we genuinely need to price your order. Nothing here is asked for a mailing list.
