The SAFE (an acronym for “Framework of Standards to Secure and Facilitate Global Trade”) was approved by the World Customs Organization (WCO) on June 2005 to promote the development of an international standard for the security of the supply chain, offering at the same time to those operators implementing effective measures of security within their supply chains, the opportunity to benefit from a series of trade facilitations (e.g. more rapidity in the release of goods and an access to more swift customs procedures, being them reliable and potentially low-risk operators). On 2007 this document has been complemented with a new section on the AEO (Authorized Economic Operator), which furtherly detailed the conditions for the access to the program, as well as the requirements for both Customs and operators that desire to be part of it.
