español al inglés Jurídico/Patentes Derecho: patentes, marcas registradas, derechos de autor Pharmaceutical Products

This phrase comes up in a letter from the Mexican "Comisión Federal para la Protección contra Riesgos Sanitarios". The agency is telling a pharmaceutical company which documents it needs to submit in order to receive approval to distribute its drug.

It says "...los requisitos documentales ... asi como los formatos ... son los siguientes:

Licencia Sanitaria
Aviso de Responsable Sanitario
Copia de registro sanitario

.... several other documents ...

Permiso de importación ... and last:
*Guía terrestre, marítima, área* [this should be 'aérea', I think]

I could translate this as "Land, sea and air guide" but I have no idea what this item means, so I don't know if I would be saying it right.

What type of 'guía' is this, and what is the correct English for this?

Thanks for your help.
