Grade 0 Mold Growth (Report No. 2025FM00761R01D)
Vapor-phase anti-mold chips suppress spore germination. According to test report No. 2025FM00761R01D from Guangdong Provincial Microbiological Analysis and Testing Center (method DA/T 26-2000, issued 2025-02-26) — Grade 0 over 28 days (8 mold species, paper/cloth/leather). Not a desiccant substitute.
Global Brand Compliance
DMF-free (SGS report No. CANAF26001423001, not detected < 0.1 mg/kg). REACH SVHC Compliance Test (SGS report No. CANAF26001423003) — 251 SVHC substances + 4 potential SVHCs, all not detected (≤ 0.1% w/w). CLP updates and brand audit packs available on request.
Asia-Wide Humidity Detection
Complimentary on-site warehouse humidity scanning and moisture risk auditing across footwear manufacturing hubs in Asia.
Free Warehouse Disinfection
Free professional warehouse mold eradication and fumigation services for nominated long-term corporate supply chains.
A505 and C304 share the same active ingredient formulation and are covered by the same mold growth test report (No. 2025FM00761R01D).
Short answer: A505 is a vapor-phase anti mold chip for sealed shoe boxes on footwear export lines. It is not a desiccant. Place one chip per sealed box; for ocean freight, pair with container desiccant poles. Legal manufacturer: Guangzhou Thirty Anti Mold and Antibacterial Technology Co., Ltd. (brand Bester). A505 is a SKU, not the company name.
Limitations
- Grade 0 lab results apply to the tested substrates, DA/T 26-2000 method, and 28-day cycle — they do not replace factory humidity control.
- A505 suppresses spore germination; it does not remove existing mold stains.
- High material moisture, wet warehouses, or container rain can overwhelm box-level chips alone.

Frequently Asked Questions
Is Bester A505 stronger than an ordinary anti mold sticker?
Yes for sealed shoe-box export use. Ordinary anti mold stickers often rely on limited contact-area protection. A505 is a vapor-phase anti mold chip: once the box is sealed, active vapor fills the micro-environment to help suppress mold on suede and leather during storage and ocean freight. Brand programs typically also request REACH screening and DMF-free documentation.
When should I choose A505 chip vs C304 anti mold bag?
Choose A505 anti mold chip for upgraded / high-value footwear export lines. Choose C304 anti mold bag for standard high-volume packing. Both outperform basic stickers in enclosed packaging via vapor-phase action. For ocean containers, pair box-level chips or bags with Bester container desiccant poles.
What REACH documentation do brand auditors typically request for A505?
As a Nominated Supplier for global brands, Bester provides comprehensive compliance packages for third-party factories. This includes the latest SGS REACH SVHC Compliance Test — 251 SVHC substances + 4 potential SVHCs, all not detected (≤ 0.1% w/w). During factory compliance audits, auditors typically require this SGS certification alongside our product MSDS to verify chemical safety for export to Europe and the US.
How do anti mold chips compare to other forms of protection?
Read our detailed comparison: Anti Mold Chip vs Sticker vs Bag. For packing-line placement, see the How to Use Anti Mold Bags guide (chip and bag SOPs side by side).
How to use an anti mold chip?
Place one A505 chip in each sealed shoe box before packing. Keep the sachet closed — it works as a vapor-phase insert, not by wiping the shoe. Protection typically lasts up to 6 months in sealed packaging stored cool and dry.
What is a mold prevention chip?
A mold prevention chip is a small slow-release insert that emits anti-fungal vapor inside sealed packaging. It is not a desiccant. It helps suppress mold on shoes, leather and textiles during storage and shipping without coating the product.
Anti mold chip vs anti mold sticker — what is the difference?
Buyers often use chip and sticker interchangeably. Ordinary stickers mainly protect near the contact patch. A505 is a vapor-phase anti mold chip: once the box is sealed, vapor fills the micro-environment. See chip vs sticker vs bag.
Can I use an anti mold chip together with silica gel?
Yes. Silica gel or a hybrid desiccant absorbs moisture; the chip inhibits mold. For ocean freight, pair box-level A505 chips with container desiccant poles.
I already use silica gel packets. Do I still need an anti mold chip?
Yes if the complaint is mold, not only dampness. Silica gel absorbs water but does not inhibit spores. When packets saturate, mold can still appear. Read why silica gel packets fail.
Are Bester products PPWR compliant?
Yes. Anti-mold inserts are packaging components under the PPWR. Bester meets Article 5 heavy metals (sum of Pb, Cd, Hg and Cr(VI) ≤ 100 mg/kg), plus DMF and REACH SVHC. See PPWR notes and SGS report numbers.
Is placing A505 chips enough to stop export mold claims?
Not always. A505 is the last line of defense inside a sealed shoe box. High material moisture, a damp warehouse, or container rain can still overwhelm the pack. Cooperating customers can add Bester factory audit and humidity testing to manage the full export chain.
Is a chip or bag enough on its own?
A505 / C304 is the last line of defense — a wet factory or warehouse can still overwhelm the pack
Many factories treat packing as “one chip per box and done.” Mold claims usually start earlier: high material moisture, poor warehouse ventilation, or container rain. Vapor-phase chips suppress spore germination; they cannot dry out a wet line.
