There are strict requirements for the importation of toys.
For example, there are requirements regarding the toys’ physical, mechanical, chemical, electrical, flammable and noise level properties. In addition, there are requirements for the labelling and packaging of toys. All toys shall be CE labelled. Toys that appeal to children under the age of three, which may be dangerous to the children, shall be marked individually.
It is your obligation as the importer to ensure that the toys meet the requirements. Norwegian Customs can detain toys that are not CE labelled or otherwise violate international standards.
