What is the difference between the Part 1 and Part 2 Guidelines?

The NSG Part 1 Guidelines govern the export of items that are especially designed or prepared for nuclear use. These include: (i) nuclear material; (ii) nuclear reactors and equipment therefor; (iii) non-nuclear material for reactors; (iv) plants and equipment for the reprocessing, enrichment and conversion of nuclear material and for fuel fabrication and heavy water production; and (v) technology (including software) associated with each of the above items. These items are known as Trigger List Items as the transfer of an item triggers safeguards.

The NSG Part 2 Guidelines govern the export of nuclear-related dual-use items and technologies, that is, items that can make a major contribution to an unsafeguarded nuclear fuel cycle or nuclear explosive activity; but that have non-nuclear uses as well, for example in industry. These items are known as Dual-Use Items.
