(a) Charging letters. The Director of the Office of Export Enforcement (OEE) may begin administrative enforcement proceedings under this part by issuing a charging letter. The charging letter shall constitute the formal complaint and will state that there is reason to believe that a violation of this part has occurred. It will set forth the essential facts about each alleged violation, refer to the specific regulatory or other provisions involved, and give notice of the sanctions available under the Act and this part. The charging letter will inform the respondent that failure to answer the charges as provided in § 280.207 of this part will be treated as a default under § 280.208 of this part, that the respondent is entitled to a hearing if a written demand for one is requested with the answer, and that the respondent may be represented by counsel, or by other authorized representative. A copy of the charging letter shall be filed with the administrative law judge, which filing shall toll the running of the applicable statute of limitations. Charging letters may be amended or supplemented at any time before an answer is filed, or, with permission of the administrative law judge, afterwards. The Department may unilaterally withdraw charging letters at any time, by notifying the respondent and the administrative law judge.

(b) Notice of issuance of charging letter instituting administrative enforcement proceeding. A respondent shall be notified of the issuance of a charging letter, or any amendment or supplement thereto:

(1) By mailing a copy by registered or certified mail addressed to the respondent at the respondent's last known address;

(2) By leaving a copy with the respondent or with an officer, a managing or general agent, or any other agent authorized by appointment or by law to receive service of process for the respondent; or

(3) By leaving a copy with a person of suitable age and discretion who resides at the respondent's last known dwelling.

(4) Delivery of a copy of the charging letter, if made in the manner described in paragraph (b)(2) or (3) of this section, shall be evidenced by a certificate of service signed by the person making such service, stating the method of service and the identity of the person with whom the charging letter was left. The certificate of service shall be filed with the administrative law judge.

(c) Date. The date of service of notice of the issuance of a charging letter instituting an administrative enforcement proceeding, or service of notice of the issuance of a supplement or amendment to a charging letter, is the date of its delivery, or of its attempted delivery if delivery is refused.
