Procedure for supplementary declarations
If you have previously submitted a simplified declaration or entry in the declarants´s records, it should be followed by a supplementary declaration.
If a simplified declaration has been submitted to Swedish Customs or if a customs declaration has been lodged via entry in the declarant's records, a supplementary declaration must be submitted within 10 days of release. This is the process for lodging a supplementary declaration under the new import procedure.
