An EAR99 designation is reached after an item, data, or service is not found to be export controlled under the US Munitions List (USML) or the Commerce Control List (CCL). The EAR99 classification means that the item, data, or service will not need any approvals or export under a special exemption or exception to leave the United States.
Another designation often used to accompany the EAR99 classification is "No License Required" or NLR. So, a popular designation that some use is EAR99-NLR.
Be aware that an EAR99 designation doesn't mean that something can be exported from the U.S. to anywhere in the world. The U.S. has embargoes and sanctions with various countries and those embargoes apply to EAR99 related exports. There are approvals that can be obtained to export EAR99 to embargoed nations but typically the approvals are for humanitarian reasons.
Also, and this is important, understand that exports can occur in and outside the USA and include any form of transfer. Emails, hand carry, meetings, dialogue, documents, videos, pictures, etc. is considered an export just like boxing and shipping to a foreign party.
