(b)Exception. If the Center director determines that an importation described in paragraph (a) of this section is part of a series of importations carried out or planned for the purpose of evading compliance with the certification requirements of § 10.584 of this subpart, the Center director will notify the importer that for that importation the importer must submit to CBP a copy of the certification. The importer must submit such a copy within 30 days from the date of the notice.
