11. 关于为识别和跟踪目的对爆炸物作标识或标签，专家组注意到，虽然有着某些相似之处，但爆炸物不是枪支，而且对标签的需要所提出的问题也不同于枪支、机动车辆和其他此类器械上使用的序号或其他独特的标识的问题。用于在爆炸之前识别和跟踪目的的标识一般是在爆炸物的包装上刻印、雕印或压印出有关信息，因为许多爆炸物是软的、半固体或甚至是液体材料，不能使用永久性标识。即使使用了这类标识，在许多情况下，爆炸物也能够轻易地被那些想隐瞒其特性或来源的人加以重新包装或组成。用于爆炸后识别目的的标识提出了更大的技术挑战。由于爆炸后爆炸物及其包装被完全毁坏，在标识方面的努力集中于添加在爆炸后可留下不同的微粒或残余物的物理或化学物质上。由于变化的数目比起诸如序号等物理标识要少得多，能够附上的信息量很有限。多数情况下，目前的爆炸物标签只能识别制造公司或产地以及大概的制造日期或生产批号或批次。
11. Regarding the marking of explosives for the purpose of identification and tracing, or tagging, the Group noted that, while there were some similarities, explosives were not firearms, and the issues raised by the need for tagging were different from those involved with attaching and using serial numbers or other unique markings used on firearms, motor vehicles and other such items. Marking for the purpose of identification and tracing prior to detonation generally involved information stamped, embossed or stencilled onto the casings into which the explosive is packed, since many explosives were soft, semi-solid or even liquid materials that would not accept permanent markings. Even when such markings were applied, in many cases the explosives could be easily repacked or reconstituted by those wishing to conceal identity or origin. Marking for the purpose of post-detonation identification represented even greater technical challenges. Since the explosive and its casing were completely destroyed, efforts to mark had focused on the addition of physical or chemical substances that would leave distinctive particles or residues after detonation. Since the number of variations was much more limited than with physical markings such as serial numbers, there was a limit to the amount of information that could be attached. In most cases, explosive tagging would currently identify only the company or place of manufacture and possibly the approximate date or production lot or batch of its manufacture.
