Product testing summary
| Test | Standard / Method | Result | Report Source | Products Covered |
|---|---|---|---|---|
| Mold Growth Rating | DA/T 26-2000 (28-day test, 8 mold species) | Grade 0 — zero visible mold growth on paper / cloth / leather | Guangdong Detection Center of Microbiology — 2025FM00761R01D | A505 + C304 (same active composition) |
| REACH SVHC Screening | REACH Regulation (EC) No 1907/2006 | 251 SVHC + 4 potential SVHCs — all not detected (≤ 0.1% w/w) | SGS — CANAF26001423003 | A505, C304 |
| DMF Content | DMF (dimethyl fumarate) detection | Not detected (< 0.1 mg/kg) | SGS — CANAF26001423001 | A505, C304 |
| PPWR packaging heavy metals | (EU) 2025/40 Art. 5(4); CEN CR 13695-1:2000 | Sum of Pb+Cd+Hg+Cr(VI) ND (limit ≤ 100 mg/kg) — Pass | SGS — bag CANAF26023374803_1; desiccant CANAF26023374801_2; pole CANAF26023374805 | C304 bag (incl. chip parts), desiccant, container poles |
Note: Report 2025FM00761R01D is titled “Bester Anti-mould bag.” Because A505 chips and C304 bags use the same active composition, this Grade 0 result applies to both SKUs. Packaging variants listed on the report (3×4 CN/EN, purple, orange) are similar packaging of the same product family.

Factory Quality Control
Our mold prevention protocol covers three production stages:
| Stage | Process | Output |
|---|---|---|
| Before Production | Factory environment audit (humidity, ventilation, storage) | Mold Risk Assessment Report |
| During Production | Material moisture testing, in-line humidity checks | Production Humidity Log |
| Before Shipment | Warehouse inspection, packaging verification, container desiccant placement | Pre-Shipment Mold Risk Report |
[Factory photos to be added] — see also About Us and Case 08 audit walkthrough.

Limitations
- Lab Grade 0 applies to the tested substrates, DA/T 26-2000 method, and 28-day period — not a guarantee for every factory climate or packing error.
- Anti-mold chips/bags inhibit spore germination; they do not reverse existing mold stains.
- Report 2025FM00761R01D is issued on the anti-mould bag sample name; A505 coverage is by same active composition as stated by the manufacturer.
FAQ
Are Bester anti-mold products REACH compliant?
Yes. REACH SVHC Compliance Test — 251 SVHC substances + 4 potential SVHCs, all not detected (≤ 0.1% w/w). SGS Report No. CANAF26001423003.
Do Bester products contain DMF?
No. DMF: not detected (< 0.1 mg/kg). SGS Report No. CANAF26001423001.
What mold growth rating did A505 / C304 achieve?
Grade 0 on paper, cloth, and leather after 28 days (8 mold species). Guangdong Detection Center of Microbiology Report No. 2025FM00761R01D, method DA/T 26-2000, issued 2025-02-26. Same report covers A505 and C304 because they share the same active composition.

For factories & exporters
Home mold cleaning is not the same as export packing mold control. If you run a shoe factory or brand program, use vapor-phase anti-mold inserts (not silica gel alone) before sealing boxes.
