The competitive landscape of sanitary pad market is shifting. The group standard T/CIAA 008-2026 for antimicrobial sanitary pads, pantyliners, and period pants, released in August 2026, introduces for the first time the definition and performance requirements for "long-lasting antimicrobial" efficacy. This means antimicrobial protection is no longer a one-time claim but must remain effective under simulated use conditions. For buyers, this change directly raises the entry barrier.
Core Changes in the Standard
The most critical update is the expansion of scope. The original "bacteriostatic sanitary pads" has been renamed to "antimicrobial sanitary pads, pantyliners, and period pants," extending coverage to period pants. A new term "long-lasting antimicrobial" is added, requiring that the product's skin-contact layer be treated with bovine serum albumin and placed at (36±1)°C for at least 8 hours to simulate actual wearing conditions, after which the product must still exhibit antimicrobial activity. This shifts testing from simple initial antimicrobial rate to residual effectiveness after simulated use.
Compared to the 2020 version, the new standard fully aligns with GB 15979-2024 for disposable sanitary products, systematically adjusting requirements for antibacterial performance, bacteriostatic performance, stability, and toxicology. It also adds a long-lasting antimicrobial performance requirement. Test methods have been updated accordingly, including a new procedure for evaluating sustained efficacy. This is not a minor revision but a fundamental change in testing logic—from "whether it works" to "whether it keeps working."
Industry Impact: Cost and R&D Challenges
For upstream suppliers of nonwoven fabrics, absorbent cores, and antimicrobial agents, the new standard will force formulation upgrades. Traditional antimicrobial finishes may not pass the long-lasting test, necessitating the development of more durable, migration-resistant solutions. This directly impacts material selection for the topsheet and absorbent layers, with particular focus on how antimicrobial agents are fixed on the skin-contact layer.
For contract manufacturers, testing costs will inevitably rise. The long-lasting antimicrobial test requires additional equipment, reagents, and time, potentially extending the testing cycle to several days. Small and medium factories without in-house testing capabilities must rely on third-party labs, and the costs will be passed on to product pricing. This means that verification costs for antimicrobial performance will become a new variable in price negotiations.
Brands must also adjust their product registration and marketing strategies. Previously, "antibacterial" claims only required an initial antibacterial rate report; now they must include long-lasting data. This may force some products out of the market, especially in low-price segments where substandard antimicrobial products will find it harder to survive.
Practical Recommendations
For Purchasers - Require suppliers to provide test reports under the new T/CIAA 008-2026, focusing on long-lasting antimicrobial data rather than just initial rates. - For period pants, confirm that products are covered by the new definition to avoid compliance risks. - Include standard-change clauses in contracts to ensure timely notification and alternative plans if suppliers cannot meet upgraded requirements.
For Foreign Trade Companies - Assess whether target export markets recognize Chinese group standards; consider dual compliance with ISO or local standards. - Monitor import restrictions on bovine serum albumin in destination countries to avoid delays in testing. - Establish long-term partnerships with testing agencies and book long-lasting antimicrobial test slots in advance to handle peak order seasons.
The implementation of the new standard will take time, but the direction is clear: competition in antimicrobial sanitary pads will shift from concept to evidence. Whoever adapts to the logic of long-lasting efficacy first will gain an advantage in the upcoming industry reshuffle.
