130 Mailability
131.1 Domestic Limits
All articles that are nonmailable in domestic mail are nonmailable in
international mail. See DMM 601 and Publication 52, Hazardous, Restricted,
and Perishable Mail.
131.2 International Limits
Many articles that are mailable in domestic mail are nonmailable in
international mail. See section 630 of Publication 52 and "Prohibitions and
Restrictions" in the Individual Country Listings.
131.31 Information Available
Information on articles that are prohibited or restricted to individual countries
appears under "Prohibitions and Restrictions" in the Individual Country
Listings. These prohibitions and restrictions are based on information
furnished by the countries concerned. Customers should inquire at the Post
Office facility about specific prohibitions or restrictions.
131.32 Prohibited and Restricted Articles
Articles that are prohibited by the destination country are nonmailable. For
mail known to contain articles restricted by the destination country, the sender
must be informed of the restrictions and advised that the articles are subject
to the import requirements of that country.
131.33 Return or Seizure of Mail
A country may return or seize mail containing articles prohibited or restricted
within that country, whether or not notice of such prohibition or restriction has
been provided to or published by the Postal Service.
131.34 Foreign Customs Information
The Postal Service does not maintain or provide information concerning the
assessment of customs duty in other countries. Postal Service employees
must not attempt to inform customers whether articles (gifts or commercial
shipments) will be subject to customs duty. Postal Service employees may
suggest to customers, however, that they inform the addressees in advance
of the articles they intend to mail. Addressees can then obtain information
from their local customs authorities. No provision is made for prepayment of
customs duty on mail addressed for delivery in foreign countries.
If duties or taxes are assessed, most countries will collect from the recipient a
customs clearance and delivery fee, in addition to the duties and taxes. This
fee is authorized by international postal agreements to reimburse the delivery
service for the costs it incurs in clearing the items through customs and
collecting duties at the time of delivery. The duties, taxes, and fee, if
applicable, are not included in the postage paid by the mailer.
131.4 Mailer Responsibility
Regardless of any statement in this manual or the statement of any employee
of the United States Postal Service, the burden rests with the mailer to
ensure compliance with domestic, international, and individual country rules
and regulations for mailability.
131.5 Preparation for Mailing
131.51 General Packaging Requirements
Parcels of articles or goods must meet the requirements of DMM 601. The
size and weight limits for each of several grades of fiberboard boxes are as
specified for difficult loads in DMM 601. Reinforce boxes in each of two
directions around the package.
131.52 Special Packaging Requirements
Each mailer must meet the following special packaging requirements when
mailing any of the following articles (see DMM 601):
a. Fragile articles, such as glass, must be cushioned as required to
dissipate shock and pressure forces over as much of the surface of the
item as possible.
b. Liquids must be packaged as required.
c. Package fatty substances that do not easily liquefy, such as ointments,
soft soap, resins, etc., as well as silkworm eggs, in an interior container
(box, cloth, or plastic bag) and place them in an outer shipping
container of minimum 275-grade test strength.
d. Enclose dry, powdered dyes, such as aniline, in sift-proof, sturdy tin or
plastic boxes in an outer sift-proof shipping container. This container
must have a minimum 275-grade test strength fiberboard or equivalent.
132 Written, Printed, and Graphic Matter
132.1 Domestic Limits
All written, printed, and graphic matter that is described as nonmailable in
DMM 601 is nonmailable internationally. This matter includes but is not
limited to:
a. Advertisements for abortion.
b. Advertisements for motor vehicle master keys.
c. Copyright violations.
d. Fictitious matter.
e. Lottery matter.
f. Matter inciting violence.
g. Solicitations in the guise of bills or statements of account.
h. Solicitations or inducements for mailing harmful matter, radioactive
materials, controlled substances, or intoxicating liquors.
Note: Immoral or obscene articles and advertisements for them are
nonmailable.
132.2 Reply Cards and Envelopes
Mailpieces that are sent to foreign addressees may not contain prepaid reply
cards or envelopes that bear a U.S. postage stamp, meter stamp, meter
impression, or a domestic business reply indicia. See 373 for
regulations governing mailer use of International Business Reply Service
(IBRS).
Exception: The prohibition against enclosing U.S. domestic business
reply cards or envelopes does not apply when they are bound into, are
stapled to, or form an integral part of the printed page of mailpieces that
are paid for at publishers' periodical rates. Such enclosures may be
admitted so long as they are not used as response vehicles by foreign
recipients and the postal administrations of the destination countries do
not object to their presence in U.S. origin publications.
133 Improperly Addressed Mail
The following items are nonmailable in international mail:
a. Unaddressed items.
b. Items whose ultimate destination cannot be determined due to
insufficient, illegible, or incorrect addressing.
c. Items bearing multiple addresses to the same or different countries.
134 Valuable Articles
134.1 List of Articles
The following valuable articles may be sent only in registered letter-post
mailpieces or by insured parcel post and are not mailable in Global Express
Mail (EMS) or ordinary parcel post shipments (see 221.2 and 281.2):
a. Coins, banknotes, and currency notes (paper money).
b. Instruments payable to bearer. (The term "instruments payable to
bearer" includes checks, drafts, or securities that can be legally cashed
or easily negotiated by anyone who may come into possession of them.
A check or draft payable to a specific payee is not regarded as payable
to bearer unless the payee has endorsed it. If not endorsed, or if
endorsed in favor of another specific payee, it is not regarded as
payable to bearer.)
c. Traveler's checks.
d. Manufactured and unmanufactured platinum, gold, and silver.
e. Precious stones, jewels, jewelry, watches, and other valuable articles.
Note: The term "jewelry" is generally understood to denote articles
of more than nominal value. Inexpensive jewelry, watches, such as
tie clasps and costume jewelry, containing little or no precious
metal, is not considered to be jewelry within the meaning of this
section and is accepted under the same conditions as other
mailable merchandise to any country. Inexpensive jewelry is
accepted to countries that prohibit jewelry, but only at the sender's
risk.
Individual countries prohibit or restrict some or all of the valuable items listed
above. See the "Prohibitions and Restrictions" section in the Individual
Country Listings.
