Specialists in CCC / SRRC / Network Access License services · Bao'an, Shenzhen · Serving all of China
Founded in Shenzhen in 2016, Shenzhen CTLC Testing Technology Co., Ltd. is a technology-driven service provider built around CCC (China Compulsory Certification), SRRC radio type approval and the telecom equipment Network Access License — three mandatory certifications that form our core business.
Unlike agencies that only run paperwork, we built our own standardized lab: EMC, RF, electrical safety and communication-terminal pre-testing, hardware rectification and re-testing all happen in-house. Formal type tests and network access testing are reported by officially designated labs, with our engineers on site throughout. When a metric fails, we locate and fix it on the spot — one less rework round means a shorter timeline.
Our founding team has long served manufacturers in electronics, wireless communications and BeiDou navigation, and has seen too many companies stuck at the same point: a failed submission with no in-house team able to change the hardware — so they switch labs, resubmit samples and queue again, while prototype and tooling costs pile up and the launch window closes.
So from day one CTLC took the technical route: build the lab, keep rectification capability in-house, and run "assessment — pre-testing — rectification — re-testing — filing — factory audit — certification" as one chain instead of throwing problems back to the client. That is also why we handle only these three mandatory certifications: going deep on one thing beats doing a little of everything.
Catalog determination, unit division, designated labs and review scheduling — every certificate has its own know-how. Focusing on three mandatory certifications means more accurate assessments, more familiar processes and fewer detours.
