As of Thursday (April 15), all toys sold in Vietnam, produced locally or imported, will need to produce safety certificates mentioning their pH level and formaldehyde content.
The new rule is part of the National Technology Standards on Safety for Children's Toys issued by the Ministry of Science and Technology.
Children's toys must have pH levels between 3 and 10.
Specific caps have also been placed on the amount of different kinds of formaldehyde found in fabric and the toys' wooden parts.
Toys should not use a power source with the nominal voltage larger than 24V.
Most toys sold in Vietnam come from China with no labels stating their ingredients or substances they contain. Also, many imported toys don't carry labels in Vietnamese.
