China , October 23, 2025 — China’s National Medical Products Administration (NMPA) has officially released 38 new and revised YY/YY-T industry standards for medical devices and in vitro diagnostics (IVDs). These standards establish the baseline for type testing and dossier preparation in device registrations. Most will take effect on July 1, 2026, with a few scheduled for 2027 and 2028.
NMPA Medical Device Standards: GB vs. YY – The Foundation of China’s Standards System
China’s regulatory system distinguishes between GB (national) and YY (medical device) standards:
- GB / GB-T: National standards; GB indicates mandatory requirements, while GB-T is recommended.
- YY / YY-T: Industry-specific medical device standards; YY is mandatory, YY-T is recommended but often expected in practice.
Even though YY-T standards are technically voluntary, reviewers at CMDE routinely use them as benchmarks during type testing and technical reviews. Compliance with applicable GB and YY standards determines your product’s testing, labeling, and performance claim requirements in China.
China Regulatory Updates: Key Themes Across the 38 Standards
The newly published standards span multiple device categories — from dentistry and implants to IVDs, imaging, software, sterilization, and robotics. Highlights include:
- Labeling and IFU: YY/T 1960—2025 establishes requirements for information supplied by the manufacturer, covering labels, packaging, and accompanying documentation.
- Imaging and Radiology: YY/T 0310—2025 for CT scanners and YY/T 1959—2025 for intraoral digital X-ray imaging systems.
- IVDs: New analyte-specific standards such as YY/T 1958—2025 (17-OHP immunoassay) and YY/T 1963—2025 (CRC gene methylation PCR).
- Implants: YY/T 1982—2025 defines porous structure morphology testing for surgical implants.
- AIMDs: YY 0989.6—2025 updates requirements for implantable cardioverter-defibrillators (ICDs).
- Software & Radiotherapy: YY/T 1968—2025 (PGT-A software) and YY/T 1981—2025 (RT planning software).
- Rehabilitation & Robotics: YY/T 1973—2025 sets performance and testing criteria for lower-limb exoskeleton robots.
The NMPA continues to expand these categories each year, transforming prior guidance into formalized, enforceable technical baselines.
Impact on CE-Marked and FDA-Cleared Manufacturers
A common misconception is that IEC, ISO, or FDA/MDR compliance automatically satisfies China’s requirements. In reality, NMPA mandates testing and conformity to GB/YY standards, even when international evidence exists. Local type testing, Chinese-language labeling, and specific performance criteria must be met before registration approval.
Differences to anticipate:
- Documentation must follow Chinese formats, including Product Technical Requirements (PTR) and IFUs in Chinese.
- Type testing is executed at CN-accredited laboratories using GB/YY methodologies.
- Product-specific YY standards override international norms when both apply.
- Transition to the new editions will begin on their respective effective dates, so submission timing is critical.
Segment-Wise Impact Overview
In Vitro Diagnostics (IVDs)
Multiple new YY-T standards define assay-specific requirements — performance, stability, labeling, and storage conditions. Manufacturers should map their existing verification data against these standards and plan bridging studies where methodologies differ from CLSI or IVDR norms.
Implants and Orthopedics
The porous structure morphology standard introduces detailed test methods for porosity, connectivity, and pore size. Firms using ASTM or ISO AM data will need to re-analyze morphology according to the Chinese clauses.
Active Implantable Devices and Cardiology
Updated ICD standards redefine functional safety, electromagnetic compatibility, and device longevity parameters. Manufacturers must align their technical documentation with the new functional limits and classification boundaries.
Imaging Equipment
Revised CT and intraoral X-ray standards impose device-specific test setups and performance tolerances. Existing IEC data may assist but cannot substitute for China-based validation.
Software and Radiotherapy
New SaMD standards for PGT-A and RT planning software outline dataset validation, accuracy thresholds, and reporting rules. Global evidence must be cross-referenced with the YY/T requirements.
Dialysis and Extracorporeal Systems
The peritoneal dialysis equipment standard clarifies inclusions and exclusions, requiring updated type-testing matrices by 2027.
Labeling and IFU
The new YY/T 1960—2025 standard serves as the core labeling framework. It influences every device class and will require revisions to IFUs, packaging, and warnings.
Implementation Timeline
- Effective July 1, 2026: Majority of the new YY/YY-T standards
- Effective January 1, 2027 / July 1, 2027 / July 1, 2028: Select equipment and implant standards
Manufacturers should plan type testing and submissions accordingly, as Chinese labs and reviewers immediately transition to the latest editions upon their effective dates.
Preparing for Compliance: A 10-Step Strategy
- Map applicable standards across GB/GB-T/YY/YY-T for each SKU.
- Conduct a gap analysis against your IEC/ISO/ASTM/CLSI data.
- Engage CN-accredited labs early for testing reservations.
- Update labeling and IFUs per YY/T 1960—2025.
- Revise the PTR to reflect China-specific performance claims.
- Adapt software validation documentation to new SaMD standards.
- Re-analyze implant morphology following YY/T 1982—2025.
- Review clinical evaluation narratives to align with new test endpoints.
- Update QMS and SOPs referencing the revised standards.
- Coordinate with importers/distributors to manage transition stock and labeling.
Common Compliance Pitfalls
- Relying solely on ISO/IEC data without GB/YY cross-references.
- Ignoring “recommended” YY-T standards, which reviewers still expect.
- Delaying labeling updates, especially those tied to YY/T 1960—2025.
- Underestimating lab scheduling constraints post-implementation.
- Submitting unaligned performance claims that conflict with standard-defined test limits.
FAQ
- Are all 38 standards mandatory?
Only those prefixed with “YY” are mandatory; “YY-T” standards are recommended but routinely applied in reviews. - Will existing CE or FDA test data acceptability?
Partially. They can supplement but not replace local type testing under GB/YY methods. - Where to access the official framework?
