China — AI-generated content labelling rules in force (GB 45438-2025)
China (CAC, MIIT, MPS, NRTA) · China
What changes
The Measures for Labeling AI-Generated Synthetic Content and mandatory standard GB 45438-2025 apply. Every provider of generation and synthesis services in mainland China must add an implicit label in file metadata (an "AIGC" field) (Measures Art. 5). Where the generated content may cause public confusion or misidentification (Deep Synthesis Provisions Art. 17(1), applied by Measures Art. 4), providers must also add a label people can see or hear on generated text, images, audio, video and virtual scenes, and keep it in files users download or export. Distribution platforms must read that metadata and flag AI content, app stores must check labelling, and labels may not be removed or forged. Watermarks are encouraged, not required.
What to do
Add an AIGC metadata field to every generated file. Where your outputs may cause public confusion or misidentification (Deep Synthesis Provisions Art. 17(1)), also add a visible or audible label for each output type. Describe your labels in the user agreement, and keep logs of any output given without the visible label at a user's request for at least 6 months.
