National Marking Practices
Colombia uses an alphanumeric system. There is no one obligatory method but the method used must ensure permancy, durability, indebility and uniformity. Each weapon must be stamped with INDUMIL-COLOMBIA followed by a number. On every piece of ammunition the sign IM corresponding to INDUMIL, the batch number, calibre and date of production is stamped on the cartridge. In addition, on the inside of the lid of the container or box is stamped the day, year and month of production, as well as the batch number. It is worth highlighting that Colombia is one of the few countries which marks ammunition and explosives by number and batch.
Marking at the time of import:
Imported weapons must be duly marked and numbered by the manufacturer. once processed through Customs, the number of each weapons is registered. The arms are then discharged and sent to the various commercial stores of the of the Military Industry of Colombia, where they are entered into a central record. Once sold, details of the transfer and licence must be submitted.
SALW are therfore marked with the name of the manfacturer, year of production, model, calibre, year of import, and number of the contract.
