An Export Control Classification Number, or ECCN, is not required for HDF software, because of the nature of the software and its distribution. The HDF Group is a non-profit organization. The HDF Group’s software is free of charge and available for download without restriction, and is designed for installation by the user without further substantial support by the supplier. HDF technologies therefore have the NLR, or No License Required, designation for ECCN classification.
Referencing the Electronic Code of Federal Regulations (Title 15 Commerce and Foreign Trade, Section 734.7(b)), HDF software is available for general distribution for free and does not contain encryption. Therefore, our software is not subject to EAR and does not require an export license. For the actual regulation, see
