The antimicrobial sanitary product segment has reached a critical technical turning point. In August 2026, the revised group standard T/CIAA 008—2026 for antimicrobial sanitary pads, pantyliners and period pants was officially released, replacing the six-year-old 2020 version. This is not a simple textual patch but a full alignment of product definitions, performance requirements, and test methods with the latest mandatory national standard GB 15979-2024. For the first time, it introduces the concept of "long-lasting antimicrobial efficacy," simulating real-use conditions and directly raising the technical bar for the industry.
Three Core Changes in the Revised Standard
The most notable change is the expansion of the product definition. The original "bacteriostatic sanitary pads" has been redefined as "antimicrobial (bacteriostatic) sanitary pads, pantyliners and period pants," explicitly covering the rapidly growing period pants category. The product scope now includes outer cover materials, top sheets, absorbent cores, and leak-proof back films. This eliminates the gray area for products that previously claimed only "bacteriostatic" effects without covering period pants.
More critically, a new definition of "long-lasting antimicrobial (bacteriostatic)" has been added. The standard requires that the skin-contact layer be treated with bovine serum albumin and placed at (36±1)°C for at least 8 hours, simulating actual use, after which the product must still exhibit antimicrobial activity. This directly addresses the industry-wide pain point of "effective in the lab but ineffective in real use," imposing substantive requirements on formulation stability and controlled-release technology.
In terms of requirements and test methods, the new standard fully aligns with GB 15979-2024, updating antimicrobial performance, bacteriostatic performance, stability, and toxicology tests, while adding corresponding long-lasting efficacy test methods. This means companies must not only update internal quality control processes but also may need to conduct full-type inspections again.
Industry Transmission: From Testing Bodies to Upstream Material Suppliers
The revision is not an isolated event; it will trigger chain reactions across the supply chain. First, testing and certification bodies will see a surge in business—SGS (Shanghai) and the Institute of Microbiology of Guangdong Academy of Sciences, among the drafting units, are themselves authoritative testing institutions. After the new methods land, the frequency and scope of testing are expected to increase, raising testing costs.
For upstream material suppliers, the introduction of the bovine serum albumin simulation test means that antimicrobial finishes and functional masterbatches must exhibit greater resistance to sweat, humidity, and temperature. Suppliers that previously provided only basic antimicrobial rate data may be forced to upgrade to providing "post-use antimicrobial rate" data, or risk losing access to mainstream supply chains.
For industrial clusters in Henan, Fujian, and Guangdong, this standard will accelerate the survival of the fittest. Leading companies such as Henan Shulei and Jinda Nano Technology, which directly participated in drafting, have already completed technical preparation. However, many small and medium-sized OEMs that fail to update formulations and testing capabilities will be at a disadvantage in brand customers' supplier audits.
Practical Recommendations
For Buyers - Re-verify third-party test reports for existing and in-development products to confirm they include the "long-lasting antimicrobial" item and are based on T/CIAA 008—2026. - Require suppliers to provide specific parameters of the bovine serum albumin simulation test (temperature, duration, bacterial strains), and retain samples for spot checks. - Monitor the transition period of GB 15979-2024 to avoid purchasing products still produced under the old standard.
For Factories - Immediately review existing product lines against the new standard, prioritizing compliance assessment for period pants. - Re-sign technical agreements with antimicrobial raw material suppliers, clearly requiring post-use antimicrobial performance data. - Arrange internal validation of the long-lasting antimicrobial test method, either in-house or via third parties, to accumulate data in advance.
The implementation of the new standard essentially transforms "antimicrobial" from a marketing concept into a verifiable technical indicator. For buyers, this is an excellent opportunity to screen suppliers; for factories, it is a watershed for technological upgrading. Companies that adapt to the new standard first will gain a competitive edge in the next market cycle.
