§ 231.7 Forwarding.

(a) International. Parcels addressed to other countries will generally be forwarded to a new address of the addressee in the country of destination, subject to collection of redirection charges prescribed by the internal regulations of the country. A parcel may be forwarded to a third country provided it complies with the conditions required for its further conveyance, and provided, as a rule, that the extra postage is paid at the time of redirection or the country concerned is satisfied that it will be able to recover the redirection charges. The sender may forbid forwarding by a notation on the wrapper in a language understood in the country to which the parcel is addressed.

(b) Domestic. If the addressee of a domestic parcel has moved to another country do not forward the parcel. Treat it as undeliverable. If the sender of an undeliverable domestic parcel has moved to another country, or if the parcel bears a return address in another country, hold the parcel and request instructions from the International Service Division, Bureau of Transportation and International Services, Post Office Department, Washington, D.C. 20260, indicating the sender's new address, the weight of the parcel, whether ordinary or insured, and, if known, the nature of the contents.

which importers pay the customs charges directly to the Customs Service. The fee is retained by the Postal Service, and is accounted for by affixing postage-due stamps to the parcel or to a postage-due bill and canceling. The fee is authorized by international parcel post agreements as reimbursement to the Postal Service for the work it performs in clearing parcels through customs and for delivery to the addressee. The provisions of § 224.1(a)(3) through (5) of this chapter also apply. See § 261.5 (e) of this chapter concerning recording and reporting duty collections.

(b) On returned parcels. Collect the charges referred to in § 232.5(a).

(c) Storage (1) When to charge. Storage charges begin on the sixth working day after first delivery attempt has been made or first notice of available delivery has been issued to the addressee. The days on which the office is closed for business are not counted in determining the 5-day free storage period. However, after expiration of the free storage period, charges will be collected for each day thereafter that a package is on hand. This includes Saturdays, Sundays, national holidays, and the day on which delivery is effected. Storage charges are applied on packages requiring formal customs entry that are held in post office custody or on post office premises awaiting customs clearance. For formal entry packages, the charges being on the sixth working day after the date on which notice to file formal entry is mailed to the consignee (addressee), or on the sixth working day after receipt of the parcel at the office where it is to receive formal customs treatment if the customs notice has been issued at another customs port. Cooperation of customs officers should be solicited to enable post offices to collect any storage charges that may accrue on formal entry packages.

(2) Marking packages. When a package is returned to the post office after the first delivery attempt, or when a notice that the package is available for delivery is sent to the addressee, mark on the wrapper "Storage charges begin❞— and insert the date when the charges will begin to accrue. Rubber stamp item R1300-296 is available for this purpose to post offices of the first and second classes. See § 232.5(b) (4) regarding marking of undeliverable parcels on which storage charges are due.

(3) Daily charges. After expiration of the 5-day free storage period prescribed

The

(4) Accounting for charges. charges are accounted for by affixing postage-due stamps to the parcel or to a postage-due bill and canceling. If there are several parcels for one addressee the charges are applied separately on each parcel.

(5) Charges waived. When an addressee protests the rate or amount of duty assessed (see § 261.5(d) (6) of this chapter), the time required for the addressee to submit his written objection is counted, but the time required for the Customs Service to come to a decision in the matter is not counted.

(6) Parcels held beyond usual retention period. See § 232.5(b) (1) concerning

collection of storage charges on parcels held beyond the usual retention period. (d) Parcels containing letters. When

a parcel from another country is found to contain a personal communication, the office where it is discovered shall mark the wrapper "Letter enclosedCollect cents" and send the parcel forward to destination. The amount to

(a) Parcels addressed through bank or other organization. If a parcel is addressed to a bank or other organization for delivery to a second addressee, the post office will notify both addressees of the arrival of the parcel and will then deliver it to the first addressee, or hold it if the first addressee so desires. If the parcel is held, the post office will deliver it to the second addressee only with written permission from the first addressee, unless the sender has arranged for change of address as provided in § 247.6 (b) of this chapter. After delivery, the post office will keep the written authorization 1 year, for reference in case of inquiry. File the authorizations for insured and registered parcels with the addressees' receipts, and for ordinary (uninsured and unregistered) parcels in any appropriate place. If delivery to the second addressee involves forwarding the parcel to another post office, the parcel will be subject to forwarding postage as provided in § 232.4(a).

(b) Foreign dispatch notes. If parcels are received at delivery offices with dispatch notes "bulletin d'expédition" attached, they are delivered with the parcels. These forms have a space provided for the addressee's acknowledgment of receipt, but do not require signature. They must not be confused with foreign return receipts which are designated "Avis de réception" and are completed as prescribed in § 242.5(e) (1) of this chapter. If a parcel is returned as undeliverable, the post office will mark the dispatch note as well as the wrapper to show the reason for nondelivery and leave the dispatch note attached to the parcel. Dispatch notes that can not be associated with the relative parcels may be disposed of as waste after 60 days.

(a) Within United States. A parcel may be forwarded to the original addressee or to an alternate addressee at another post office in the United States by surface transportation, subject to collection on delivery of postage at the U.S. domestic zone rate. Forwarding by air must be prepaid. The post office forwarding an unprepaid parcel by surface in the United States will mark the wrapper "postage due" giving the amount of domestic postage along with storage charges if any. When delivering an unprepaid forwarded parcel, the post office will collect the necessary amount for domestic transmission in postage-due stamps even if the "postage-due" marking is omitted. The fee prescribed in § 232.1(a) is also collectible on any forwarded dutiable parcel.

(b) To country of origin. If the addressee has moved to the country of parcel's origin and no instructions are given to deliver to a second addressee in the United States, the post office will mark it "Moved," show the forwarding address of the addressee, and send by surface means (including parcels received by air) to the appropriate exchange office for return to the country of origin.

(c) To third country. If the addressee has moved to another country (other than the country of parcel's origin), or if the parcel bears instructions to deliver it to an alternate addressee in a third country, the post office will hold the parcel and request instructions from the International Service Division, Bureau of Transportation and International Services, Post Office Department, Washington, D.C. 20260. The request should inIclude the names and addresses of the sender and the addressee, or the alternate addressee, the weight of the parcel, whether ordinary, registered, or insured, and nature and value of the contents as shown on the customs declaration, so that the International Service Division may communicate with the foreign postal administration to secure forwarding postage. If the sender has indicated that the parcel is to be treated as abandoned if undeliverable as addressed, dispose of it as prescribed in § 232.5 (b) (3). See § 231.7(b) of this chapter concerning domestic third- and fourth-class parcels addressed to persons who have moved to another country.

(d) Dutiable parcels. Dispose of customs entry forms accompanying dutiable

parcels as prescribed in § 261.5 (i) of this chapter.

§ 232.5 Undeliverable.

(a) U.S. origin. Returned parcels are subject on delivery to the sender to collection of return postage and any other charges assessed by the foreign postal authorities. The amount of such charges will be indicated by the exchange office. If the sender refuses the parcel, it shall be disposed of as dead parcel post. If the sender has moved to another address in the United States the parcel may be redirected, subject to forwarding postage at the U.S. domestic zone rate. If the sender has moved to another country, the post office will hold the parcel and request instructions from the International Service Division, Bureau of Transportation and International Services, Post Office Department, Washington, D.C. 20260, indicating the new address of the sender, the amount of return charges due on the parcel, weight, whether ordinary, registered, or insured, and the nature of the contents as shown on the customs declaration tag.

(b) Foreign origin (1) Retention period. Parcels will be held at the disposal of the addressee for 30 days, except as follows:

(i) A parcel refused or known to be neither deliverable nor forwardable shall be treated as undeliverable at once.

(ii) A parcel bearing the sender's request for delivery to an alternate addressee shall be held 15 days at the disposal of the first addressee and 15 days at the disposal of the second. If the alternate addressee is at another post office, the parcel is forwarded subject to § 232.4(a), and the 15-day period begins from the date of receipt at the second office of address. Under the circumstances given in subdivision (v) of this subparagraph the parcel may be held for 30 days at the disposal of each addressee.

(iii) A parcel returned from customs custody with advice that the addressee has not complied with required customs entry procedures shall be treated as undeliverable at once.

(iv) A parcel held pursuant to § 261.5 (d) (5) shall continue to be held until the customs officer has rendered a decision on the addressee's objection concerning the rate or amount of duty assessed. If no decision is received within 30 days, the customs officer shall be requested to expedite the decision.

(v) On written request of the addressee or other person acting for the addressee, a parcel which remains undelivered may be held up to 60 days on condition that the storage charges due at the end of the first 30-day retention period are paid at the time of the request and that the storage charges which accumulate thereafter are paid every 10 days.

(vi) A parcel from Great Britain which bears request to "return forthwith to sender at sender's expense" shall be returned within 10 days, or immediately if definitely known to be undeliverable.

(2) Directory service. See 158.6 of this chapter concerning directory service to be accorded parcels of foreign origin.

(3) Marking and disposal. At the end of the retention period prescribed in subparagraph (1) of this paragraph, mark parcel and the accompanying dispatch note, if any, to show reason for nondelivery, and cross out address of the addressee but do not obliterate it entirely. Unless sender has given instructions on the wrapper or dispatch note for abandonment, return the parcel to the sender. Parcels to be returned to senders are dispatched to the appropriate exchange office by surface means, including those originally received by air. The post office of address will cross out the Par Avion label or other airmail marking. A parcel bearing the sender's instruction to abandon shall be marked "Abandoned" and sent to the appropriate dead parcel post branch for disposal, unless it has been assessed with customs duty. In the latter case, the parcel shall be sent to the collector of customs at the nearest customs port (see § 261.3 (e) of this chapter); the customs entry forms shall be returned to the collector who issued them, in the manner prescribed in § 261.5(f) (1) of this chapter.

(4) Storage charges. If a parcel to be returned to origin or forwarded to another country has storage charges due, the wrapper shall be marked with the amount so that appropriate action may be taken at the exchange office.
