Through close co-operation with Customs authorities in the US and various European countries, BIMCO has secured the support of its owner-members in combating illegal drug trafficking on merchant ships. Members are invited to sign voluntary agreements with the Customs authorities to implement strict security measures aimed at reducing opportunities for drug smuggling. In return, those participating in these programmes receive fair and correct treatment should drugs be discovered in the cargo despite agreed security measures. This may allow the ship to sail from port without, or with a minimum of delay, avoiding detention or arrest and exposure to heavy penalties.
