The Hainan Provincial Market Regulatory Authority has announced the findings from its fourth-quarter 2025 supervision and sampling inspection of water-soluble fertilizers containing major nutrients within the province's distribution channels. A total of 19 product batches were tested, with 4 batches found to be non-compliant, resulting in a non-compliance rate of 21.05%.
The inspection was conducted according to the requirements of standards including NY/T1107-2020, NY1110-2010, GB 38400-2019, and GB 18382-2021. The tested parameters included: content of major elements, total nitrogen, phosphorus, potassium, biuret, water-insoluble substances, chloride ions, calcium, magnesium, secondary elements, boron, molybdenum, iron, copper, zinc, manganese, trace elements, mercury, arsenic, cadmium, lead, chromium, total thallium, and packaging labeling (including fertilizer name, nutrient content, and execution standards).
No failures were detected in safety-related indicators. The four non-compliant batches failed to meet usability requirements, with the non-conforming item identified as packaging labeling. Incomplete or non-standard information on product packaging can impact consumers' ability to correctly select and use the products. The non-compliant products identified in the inspection will be handed over to the local market regulatory authorities of the inspected entities and the claimed manufacturers for processing according to the law.
