(v) Eggs destined for delivery in Canada may be packed either in the manner prescribed in d or in wooden, papiermache, or other box of a rigid material with a well-fitting tightly adjusted lid. Each egg must be wrapped in newspaper or other protecting material and placed on end, the vacant space in the box to be filled with newspaper or other packing material so as to prevent the eggs from striking together or against the sides, top, or bottom of the box.

(c) Sealing. Sealing is compulsory for all insured or registered parcel post, and for ordinary (uninsured and unregistered) parcel post for certain countries. (See individual country items in the appendix of this Subchapter C.) Patrons must seal their own parcels, using wax, gummed paper tape, nails, screws, sewing, wire or metal bands, or other adequate means which will permit detection of any attempted depredation.

(d) Enclosure or attachment of communication. (1) Prohibited. Except as provided in subparagraph (2) of this paragraph, a communication of personal nature must not be written on, attached to, or enclosed in a parcel. If such a communication is found it will be placed in the mail if separable; if inseparable the entire parcel must be rejected.

(2) Exceptions. The following exceptions apply:

(i) In the case of a parcel for Canada, a letter, and for Switzerland, a letter or card, fully prepaid and bearing the same address as that of the parcel, may be tied or otherwise securely attached to the outside of the parcel in a manner that will prevent its becoming separated or interfering with the address of the parcel. Stamps to cover postage on the parcel must be placed on the wrapper. Stamps to pay postage on the letter or card must be placed on the envelope or the card. Parcels with such attachments are treated as parcel post.

(ii) A parcel may contain an open invoice confined to the particulars which constitute an invoice.

(iii) A file or collection of out-of-date correspondence, which has served its original purpose, is acceptable as parcel post.

(e) Addressing and mailing—(1) Addressing. The name and address of the sender and of the addressee must be legibly and correctly written in every case when possible on the parcel itself or on a label gummed thereto, and must also be written on a separate slip enclosed in the parcel. Parcels will not be accepted when addressed to a "care" in one country and the addressee (or person for whom intended) in another country or when addressed to or sent by initials, unless the initials are the adopted trade name of the senders or addressees. Addresses in ordinary pencil are not allowed, but copying ink or indelible pencil on a surface previously dampened may be used. Sufficient space must be left for the addition of necessary service notations and for stamps or labels.

(2) Mailing. Parcels may not be mailed in letterboxes. Patrons must present them at parcel post windows of post offices, where the necessary postal forms (see § 231.4) will be furnished without charge.

(f) Rates, computation and postage payment (1) Surface parcels. Surface parcel post rates are based on an initial weight unit of 2 pounds and succeeding units of 1 pound. The rates to Canada, Mexico, Central America, Caribbean islands, Bahamas, Bermuda, and St. Pierre and Miquelon are 80 cents for the first 2 pounds and 30 cents for each additional pound or fraction. To all other countries the rates are 90 cents for the first 2 pounds and 35 cents for each additional pound or fraction. In computing the postage, a fraction of a pound is charged as a full pound. Applicable rates are shown under the Parcel Post headings of the various country items in the appendix of this Subchapter C. For convenience in computing postage, ready-reference rate tables are printed in the front of the appendix of this Subchapter C as Chart 4.

(NOTE: To Canada packages are required to weigh over 8 ounces in order to be mailable as parcel post. See "Canada" country item in the appendix of this Subchapter C.)

(2) Air parcels. Air parcel post rates are based on weight units of 4 ounces, a

fraction of 4 ounces being charged as a full 4 ounces. The rates vary according to the country of address, and are shown in the appendix of this Subchapter C under the "Parcel Post" heading of each country to which the service is available.

(3) Postage not charged on postal forms. The weight of the customs declaration and other postal forms will not be included with that of the parcel in computing the amount of surface or air postage required.

(4) Placement of stamps. Place stamps in payment of postage and fees in the upper right corner of the address side of the parcel. If the wrapping is of cloth or other material to which stamps will not adhere, place them on the customs declaration tag in the space below the name and address of the addressee. § 231.4

Documentation.

(a) Customs declaration, Form 2966(1) Preparation by accepting clerk. The accepting clerk will give the sender the number of forms required for the country concerned, and will see that he fills them out in accordance with subparagraph (2) of this paragraph and any special instructions under the country item in the Directory of International Mail. Request senders to fill out declarations in ink or by typewriter. If packages are presented with declarations completed in ordinary pencil do not reject them for that reason. Enter weight of the parcel and insurance number if insured. Postmark form in the space provided and return it to the sender to be attached to the parcel as described in subparagraph (3) of this paragraph.

(2) Preparation by sender. Complete declarations in ink or by typewriter. The Postal Service assumes no responsibility for accuracy of the indications shown by the sender. Show on each declaration the following:

(i) Name and address of sender and addressee.

(ii) Disposal to be made of parcel if it proves to be undeliverable as addressed. If an alternate addressee is given, it is recommended that the sender also indi

cate whether he wishes to have the parcel returned or treated as abandoned if it proves to be undeliverable to both the original and alternate addressees. This is done by checking the ultimate disposal in addition to the one showing the alternate addressee. (See illustration in paragraph (c) (4) of this section.) Senders should give instructions for abandonment of any parcels on which they are not willing to pay the return charges mentioned in § 232.5(a) of this chapter.

(iii) A complete and accurate description of the contents in the English language. An interlineation in another language is permitted, and in some cases is required (see the appendix of this Subchapter C). For parcels containing more than one article, or articles of different kinds, state the exact quantity and value of each kind or article. A sender is permitted to declare that the contents of a parcel have no value. Also, it is not sufficient to use simply such words as "coat," or "stockings," instead the materials of which the articles are composed must be shown, as "fur coat," "silk stockings." General terms such as "worn clothing," "groceries," "presents," "merchandise," "samples," and the like, will not suffice, although in the case of quantity shipments of items such as mechanical or electrical parts, and the like, general descriptions will be accepted. If the customs declaration does not furnish enough space on which to give a complete list of the contents, an additional declaration form may be used, or the list may be placed on the wrapper, making reference to the fact on the declaration itself.

(iv) If the parcel is to be insured, show in the space provided the amount for which it is insured. (See §§ 243.4 and 243.5 (a) (2) of this section.)

(3) Affixing by sender. In addition to being tied by means of a strong cord passed through the eyelets, the tag must be bound to the parcel so that it lies flat and cannot be used as a handle to lift the parcel.

it out in accordance with § 231.6(c) (2). Enter in the spaces provided the weight of the parcel and the postage paid (not including insurance or other fees), and initial the form. For parcels mailed by Government agencies pursuant to § 221.2 (d) (2) (i) of this chapter, enter the words "Official Paid" or the abbreviation "Off. Pd." in lieu of the amount of postage. See that the form is securely attached. (See subparagraph (3) of this paragraph.)

(2) Preparation by sender.

Prepare

a parcel post sticker for each parcel. Indicate alternative disposition and place

name at bottom of the form. Do not use Form 2922 on parcels for U.S. possessions.

(3) Manner of affixing. Form 2922 should be pasted to the wrapper of the parcel, preferably on the address side, but if the shape or size of the parcel makes this impracticable, the sticker may be affixed to a tag which shall in turn be securely attached to the parcel. (4) Facsimile. The following facsimile illustrates the information which the sender and the accepting clerk will add to complete the form:

(d) Furnishing to public. Patrons requesting them may be furnished a reasonable supply of Forms 2922, 2966, and 2972 for preparation at their homes or business establishments.

(e) Airmail Label 19. See § 241.4(b) of this chapter.

(f) Forms found loose in the mail. Customs declarations and dispatch notes found loose in the mail and apparently lost from parcels in transit must be sent by airmail to the appropriate exchange office to be again attached if possible to the parcels before dispatch.

(g) Nonpostal documentation. Parcel post packages may require one or more of the forms described in Part 251 of this chapter.

66-086-67- -18

(a) At mailing office. Outgoing parcels shall be checked carefully for postage payment before they are dispatched. Shortpaid parcels which bear a return address at the office of mailing shall be either returned to the sender for the deficient postage or held and the sender requested to supply the missing postage. The original postage is still valid when the parcel is remailed. If the return address is not at the mailing office the parcel shall be dispatched to the exchange office, unless the parcel is totally unpaid.
