SCOMET classification amendment tightens export controls by redefining controlled items, thresholds and cryptography rules. Amendment revises the SCOMET list by reclassifying specified radioactive and nuclear materials into Category 0, updating glossary definitions (including Cryptography and 'Contouring control'), and substituting numerous SCOMET entries and technical notes across chemical, mechanical, electronic, cryptographic, microwave, laser, navigation, inertial, underwater, unmanned and space-related categories to modify control thresholds, functional qualifiers, exclusions and procedures. The complete Appendix 3 will be published on the DGFT web-portal and the notification enters into force after a ninety-day period.
