Mutual Recognition Arrangements (MRA)

Mutual Recognition Arrangements (MRAs) for telecommunications conformity assessment reduces technical barriers to trade in telecommunications equipment by allowing such equipment to be tested in the exporting country and assured acceptance in the importing country with minimal further regulatory action.

There are two phases in the MRA:

  • Phase I: Mutual acceptance of test reports, e.g. equipment tested and approved by overseas MRA partners will not require re-testing in Singapore and vice versa.
  • Phase II: Mutual acceptance of equipment certificates, e.g. equipment certified by overseas MRA partners can enter directly into Singapore market without requiring re-certification and vice versa.

Currently, the telecommunications equipment scope may include network terminal attachment and other equipment subject to telecommunications regulations, including wired and wireless equipment and terrestrial and satellite equipment, which may or may not be connected to a Public Telecommunications Network. For such equipment, the MRA covers electromagnetic compatibility ("EMC"), electrical safety as well as purely telecommunications aspects of the conformity assessment requirements.

The following is a list of IMDA’s existing MRA partners.

Phase II

Please refer to the Singapore Customs website for information on import, export and transhipment procedures.
