§ 550.803 - Customs procedures: Merchandise specified in 550.201.

(a) With respect to merchandise specified in § 550.201, appropriate Customs officers shall not accept or allow any:

(1) Entry for consumption or warehousing (including any appraisement entry, any entry of goods imported in the mails, regardless of value, and any informal entry);

(2) Entry for immediate exportation;

(3) Entry for transportation and exportation;

(4) Entry for immediate transportation;

(5) Withdrawal from warehouse;

(6) Entry, transfer or withdrawal from a foreign trade zone; or

(7) Manipulation or manufacture in a warehouse or in a foreign trade zone, unless:

(i) The merchandise was imported prior to 12:01 a.m., Eastern Standard Time, February 1, 1986, or

(ii) A specific license pursuant to this part is presented, or

(iii) Instructions from the Office of Foreign Assets Control, authorizing the transactions are received.

(b) Whenever a specific license is presented to an appropriate Customs officer in accordance with this section, one additional legible copy of the entry, withdrawal or other appropriate document with respect to the merchandise involved shall be filed with the appropriate Customs officers at the port where the transaction is to take place. Each copy of any such entry, withdrawal or other appropriate document, including the additional copy, shall bear plainly on its face the number of the license pursuant to which it is filed. The original copy of the specific license shall be presented to the appropriate Customs officers in respect of each such transactions and shall bear a notation in ink by the licensee or person presenting the license showing the description, quantity and value of the merchandise to be entered, withdrawn or otherwise dealt with. This notation shall be so placed and so written that there will exist no possibility of confusing it with anything placed on the license at the time of its issuance. If the license in fact authorizes the entry, withdrawal or other transactions with regard to the merchandise, the appropriate Customs officer, or other authorized Customs employee, shall verify the notation by signing or initialing it after first assuring himself that it accurately describes the merchandise it purports to represent. The license shall thereafter be returned to the person presenting it and the additional copy of the entry, withdrawal or other appropriate document shall be forwarded by the appropriate Customs officer to the Office of Foreign Assets Control.

(c) If it is unclear whether an entry, withdrawal or other action affected by this section requires a specific Foreign Assets Control license, the appropriate Customs officer shall withhold action thereon and shall advise such person to communicate directly with the Office of Foreign Assets Control to request that instructions be sent to the Customs officer to authorize him to take action with regard thereto.
