Chad
Practice Relating to the Prohibition of Certain Types of Landmines
Chad’s Law on Anti-Personnel Mines (2006) states:
The development, manufacture, production, acquisition, stockpiling, retention, offer, possession, import, transfer and use of anti-personnel mines are prohibited.
The same applies to the detached pieces and assembly pieces of anti-personnel mines, even if only partially manufactured, if it is clear that they may not be used for civilian purposes. 
Chad, Law on Anti-Personnel Mines, 2006, Article 3; see also Article 10.
The Law also states:
Notwithstanding the provisions of Article 3, State authorities are authorized to import and retain a limited number of anti-personnel mines for the training of techniques to detect, remove and destroy mines. The stockpile of anti-personnel mines to be retained for these purposes must not exceed the minimum necessary [for these purposes]. 
Chad, Law on Anti-Personnel Mines, 2006, Article 4.
Chad endorsed the Final Declaration of the Brussels Conference on Anti-personnel Landmines in June 1997.
