BNNT SP10-R Refined Puffball

Please see fulfillment notice prior to ordering

BNNT SP10 "R" designation indicates "refined." These boron nitride nanotube puffballs have had nearly all of the elemental boron removed, leaving a product that is greater than 99% hBN. The hBN is in the form of boron nitride nanotubes and other nanoparticles of hBN including BNNS-like sheets, hollow hBN cages, and other nanoparticles of hBN. BNNT SP10-R is also available in three isotope compositions. If your application requires materials free of elemental boron, SP10-R is the recommended BNNT form factor.

Export Control: BNNT has been classified by the U.S. Department of Commerce Bureau of Industry and Security (BIS) under Export Administration Regulations (EAR) as a category EAR99 item. Consequently, BNNT can be released/sold in the United States without additional authorization to foreign nationals from most but not all countries. The material can be exported to most countries as “No License Required (NLR)” item unless the Recipient or End User is restricted for EAR99 items. See lists under Export Control Restrictions and Lists.

Export Control Restrictions & Lists

For deemed export restrictions for shipments of BNNT within the U.S. see: Controlled “use” technology Question (4): Is there a deemed export license requirement for EAR99 technology? and Fundamental Research Question (1).

For export outside of the U.S. if the Recipient or End User is on the following list, an export license is required and BNNT, LLC will send a form for additional required information to complete the export control license application:

BNNT (Boron Nitride Nanotubes) are nanomaterials. All handling, processing, shipping, receiving and transportation of the material must meet all U.S. Department of Transportation and U.S. Environmental Protection Agency (EPA) regulations as well as end user country requirements as applicable.

From discussions with the U.S. EPA, BNNT should be treated as nanomaterials in an R&D phase, i.e. no special approvals are required. Customers should employ safety processes appropriate for born nitride and similar to what would be used for carbon nanotubes.

A BNNT Material Safety Data Sheet will be provided with all orders. Customers outside of the U.S. should check with their country specific safety and environmental requirements for working with novel nanomaterials.
