China to Ban Mercury Thermometers and Blood‑Pressure Monitors from Jan 1, Promoting Safer Alternatives

Breaking: China Moves to Ban Mercury Thermometers and Mercury-Containing Blood Pressure Monitors

China announced a nationwide push to ban the production of mercury-containing thermometers and mercury-based blood pressure monitors as part of a broader effort to curb mercury pollution and reduce spill risks. The policy forms a phased plan tied to international mercury controls, with full effects slated for early 2026.

The initiative follows a 2017 government notice designed to implement the Minamata convention on Mercury. The notice lays out staged measures to limit the production and trade of mercury-based products, including a prohibition on manufacturing mercury thermometers and mercury-containing medical devices.

For decades, mercury thermometers have been widely used in households across China because they are affordable, simple to operate, highly sensitive, and reliable in tough environments.Each device typically contains about one gram of mercury, a toxic heavy metal according to the national health authority.

Mercury ranks among the chemicals of greatest public health concern. Exposure can harm the nervous, digestive, and immune systems, and also the lungs, kidneys, skin and eyes.If a thermometer shatters, mercury vapor can pose inhalation and contact risks, underscoring the need for safe handling and cleanup.

Authorities emphasize that there is no need for panic if a spill occurs. Safe cleanup steps include ventilating the area by opening windows, collecting beads with cardboard, and disposing of waste at a designated hazardous waste site. Vacuum cleaners or brooms should be avoided,as they can spread mercury.

Health experts point to readily available alternatives. Safer options include forehead and ear thermometers, which require proper usage: keep a safe distance for forehead readings and ensure the ear canal is clean with the probe snugly placed for ear measurements. For those accustomed to conventional oral or underarm methods, non-mercury thermometers based on gallium-indium-tin alloys offer precise readings without mercury.

As the transition unfolds, officials stress that these mercury-free devices are widely accessible and capable of delivering accurate results while reducing environmental and health risks.

Why this matters in the long run

The move reflects a broader global shift away from mercury-based medical instruments toward safer digital technologies. By phasing out mercury thermometers and related devices, China aims to lower the likelihood of mercury spills and support environmental protection efforts while maintaining reliable temperature measurements in homes and clinics.

Safer Option Technologies

article.### Regulatory Background: China’s 2025 Health‑Safety Initiative

• Policy Announcement – In August 2024, the National Medical Products Administration (NMPA) issued Circular 2024‑08, mandating that all mercury‑containing thermometers and sphygmomanometers be withdrawn from the market by 1 January 2025.
• Legal Framework – The ban aligns with the updated Medical device Supervision Regulation (MDSR) and the Measures for the Control of Toxic Substances in Medical Products (2023). Both statutes require manufacturers to prove that their devices meet “non‑hazardous” standards before receiving a Class II or III certification.
• Enforcement mechanism –

1. Pre‑market inspection – NMPA auditors review product dossiers for mercury content.
2. post‑market surveillance – Random sampling of retail inventory; penalties include fines up to ¥5 million or suspension of business licenses.

Health Risks of mercury‑Based Medical Devices

Device	Primary mercury Form	Exposure Pathway	Documented Health Impact
Mercury Thermometer	elemental Hg (0.5-2 g per unit)	Breakage → inhalation of vapor; skin contact	Neurological deficits,kidney dysfunction (WHO,2022)
Mercury Blood‑Pressure monitor (aneroid sphygmomanometer)	Elemental Hg (≈ 50 g per cuff)	Leakage during calibration or disposal	Chronic mercury poisoning,especially in pediatric and occupational settings

– Environmental concern – Improper disposal leads to mercury leaching into soil and water,contaminating the food chain.

• Vulnerable groups – Children, pregnant women, and healthcare workers with frequent device handling are at heightened risk.
