The Army's Directorate for Inspection of Controlled Goods exercises controls (register, licensing, inspection, military customs) to prevent the manufacture, stockpiling, transfer and possession of any unmarked or inadequately marked small arms and light weapons.
Erasing or altering markings of small arms and light weapons or ammunition is a crime, subject to the penalty of 3-6 years imprisonment and fines.
