The defendant, Suikei Mayang, was released as the prosecution did not oppose his application for bail.
He was ordered to surrender his travel documents and to sign in twice a week at police headquarters in Apia.
The court heard the defendant was only charged with bribery as a result of the police investigation but a Customs inquiry was still underway.
He was reported to have offered a senior customs official a bribe worth around $US1800.
Mr Mayang will appear again in court on 11 June.
