Guangdong Tongji (广东通济司法鉴定中心) is a comprehensive judicial appraisal centre in Foshan, successor to the Foshan Medical Association’s appraisal centre, licensed by the Guangdong Department of Justice under 34440000MD8022789G and listed on the People’s Court panel of institutions courts may instruct. Its 痕迹鉴定 registration covers both 火灾痕迹鉴定 and 爆炸痕迹鉴定, and its 微量物证鉴定 registration covers 火灾微量物证鉴定, giving it the full pairing of scene trace and laboratory trace evidence. Two of its appraisers hold State Council special allowances. It is a generalist centre whose volume work is forensic medicine, so a fire instruction should be scoped to its named trace and microtrace appraisers.
