Human review
Compliance notes
DMDM Hydantoin is a formaldehyde-releasing cosmetic preservative and requires careful review against destination-market cosmetic regulations and buyer formulation limits

Confirm whether the product is classified as dangerous goods for the proposed concentration and packing under the selected transport mode; request supplier DG/non-DG statement only as supporting documentation, not as a regulatory guarantee
Check whether export documentation can match buyer-required product name, CAS No., batch number, net weight, and HS code
Supplier page references certifications such as ISO9001, ISO22716, GMPC, and BSCI; buyers should request valid certificates and confirm scope covers the relevant manufacturing or trading entity
