No special regulations apply to the exterior marking of containers for shipments to Morocco.  However, an indication on outer containers of the net weight in kilograms, together with other identification markings, will assist in locating goods on arrival and speed their clearance through customs. Duties and taxes are assessed on the value indicated on the commercial invoice

Metric measurement is mandatory.  Morocco uses the same numerals (0123456789) as those used in the United States.  The date format should be (dd/mm/yyyy).  Food labels can be in French or Arabic and must show country of origin.  Both local and imported canned foods and beverages must have the dates of production and expiration printed on them using the format above.  The Foreign Agriculture Service has prepared a Food and Agricultural Import Regulations and Standards (FAIRS) report for U.S. exporters detailing agricultural labeling requirements that can be found at: 

USDA Foreign Agricultural Service. The NM 09.000 is the standard required labeling on textile products.
