(a) Return information. Within 30 calendar days after actual receipt of a listed chemical at the importer's registered location or place of business if not required to be registered, the importer must file a report with the Administration through the DEA Diversion Control Division secure network application specifying the particulars of the transaction. This report must include the following information: The date on which the listed chemical was released by a customs officer at the port of entry; the date on which the listed chemical arrived at the importer's registered location or place of business; the actual quantity of the listed chemical released; the actual quantity of the listed chemical that arrived at the importer's location; the date of any subsequent transfer; a description of the subsequent transfer, including the actual quantity transferred, chemical, container, and name of transferees; the actual port of entry; and any other information as the Administration may specify. A single report may include the particulars of both the importation and distribution. If the importer has not distributed all chemicals imported by the end of the initial 30 calendar day period, the importer must file supplemental reports not later than 30 calendar days from the date of any further distribution, until the distribution or other disposition of all chemicals imported under the import declaration or any amendment or other update is accounted for. Upon receipt and review, the Administration will assign each completed report a transaction identification number. In determining whether the importer has complied with the requirement to file within 30 calendar days, the report shall be deemed filed on the first date on which a complete report is filed.

(b) If an importation for which a DEA Form 486/486A has been filed fails to take place, the importer must report to the Administration that the importation did not occur through the DEA Diversion Control Division secure network application.

(c) Denied release at the port of entry. In the event that a shipment of listed chemicals has been denied release by a customs officer at the port of entry for any reason, the importer who attempted to have the shipment released, within 5 business days of the denial, report to the Administration that the shipment was denied release and the reason for denial. Such report must be transmitted to the Administration through the DEA Diversion Control Division secure network application. This report must include the following information: The quantity of the listed chemical denied release; the date on which release was denied; and the basis for the denied release. Upon the importer's report of a denied release, the DEA will assign the report a transaction identification number and the import declaration will be void and of no effect. No shipment of listed chemicals denied release for any reason will be allowed entry into the United States without a subsequent refiling of an import declaration. Following such refiling the importer may request release of the listed chemicals immediately after receipt of a transaction identification number without regard to the 15 day advance filing requirement in § 1313.12(b).
