As a former LSP (Logistics Service Provider) account ececutive, and currently as a Licensed Customs Broker and consultant, I have had many clients assure me that their commodities fall under EAR99 and NLR.
EAR99 means that an item is subject to Export Administration Regulations but is not listed with a specific ECCN (Export Control Classification Number). NLR is the abbreviation for No License Required. The first step in the license/NLR decision is to determine ECCN or EAR99.
The CCL (Commerce Control List) is an index listing commodities and product groups. It is a good starting place for researching ECCNs. Here is the link for your reference:
