Overview
- An investigative report published on Thursday said journalist-commissioned tests found formamide in multiple market diaper brands and that more than 100 infant blood or urine samples showed detections, a claim the reporter backed with raw data and experimental notes.
- Major diaper brands quickly published third-party test reports saying formamide was not detected, but consumers and critics questioned the independence and sample selection of those company-submitted tests.
- Industry groups and scientific commentators flagged missing methodological details in the original report, disputed the causal link between detected blood levels and diaper use, and pointed to inconsistencies in the published evidence.
- Local market supervision bureaus in Shanghai’s Huangpu District, Hangzhou, Huzhou, Nanjing and Tianjin have launched product抽检, supply-chain traceability and company inspections while no central, authoritative conclusion has been released.
- China’s diaper national standard GB/T 28004.1-2021 does not list formamide as a routine test item or set a limit, creating a regulatory gap that experts say makes a state-level, full-chain investigation and a standards revision the only way to produce a definitive, verifiable result and rebuild trust.
