(february 23, 2024) since february 24, 2022, the department of commerce’s bureau of industry and security (bis) has implemented a series of  stringent export controls that restrict russia’s access to the technologies and other items that it needs to sustain its brutal attack on ukraine. these restrictions also apply to belarus in response to its substantial enabling of russia’s destabilizing conduct. while bis’s controls cover a vast array of items necessary to fuel russia’s war machine, certain items are more significant to russian weaponry than others. working with the  european union , japan, and the  united kingdom , bis has developed the common high priority list (chpl), which includes 50 items identified by six-digit  harmonized system (hs) codes that russia seeks to procure for its weapons programs.  in this notice, bis is publicizing these 50 common high-priority items to highlight for industry that these items pose a heightened risk of being diverted illegally to russia because of their importance to russia’s war efforts. the list may be updated periodically as new information becomes available. overview the common high priority items list (chpl) is divided into four tiers. tier 1 items of the highest concern due to their critical role in the production of advanced russian precision-guided weapons systems, russia’s lack of domestic production, and limited global manufacturers. tier 2 additional electronics items for which russia may have some domestic production capability but a preference to source from the united states and its partners and allies. tier 3.a further electronic components used in russian weapons systems, with a broader range of suppliers. tier 3.b mechanical and other components utilized in russian weapons systems. tier 4.a manufacturing, production and quality testing equipment for electric components, circuit boards and modules. tier 4.b computer numerically controlled (cnc) machine tools and components. within the chpl, bis has prioritized the nine hs codes in tier 1 and tier 2—covering items such as integrated circuits and radio frequency (rf) transceiver modules—that have extensive commercial applications but have also been found in russian missiles and drones on the battlefield in ukraine. taken together, items in tiers 1 and 2 are subject to the most comprehensive controls under the export administration regulations (15 cfr parts 730 – 774) (ear) ( see, e.g. , the controls on foreign produced items described in  part 734.9 of the ear ). items in tiers 1 and 2 have been described in previous notices issued by the u.s. government (see below). the items in these 50 hs codes include both lower technology items designated ear99, as well as more sensitive items on the commerce control list ( supplement no. 1 to part 774 of the ear ) (ccl), including items designated under export control classification numbers (eccns), 2a001, 2a101, 2a991, 2b001, 2b002, 2b003, 2b201, 2b991, 2b992, 2b993, 2b998, 3a001, 3a002, 3a090, 3a991, 3a992, 3b001, 3b991, 3b992, 5a001, 5a991, 6a002, 6a003, 6a993, 7a003, 7a994, and 9a991.   tier 1 hs code hs description and representative part 8542.31 electronic integrated circuits: processors and controllers, whether or not combined with memories, convertors, logic circuits, amplifiers, clock and timing circuits, or other circuits 8542.32 electronic integrated circuits: memories 8542.33 electronic integrated circuits: amplifiers 8542.39 electronic integrated circuits   tier 2 hs code hs description and representative part 8517.62 machines for the reception, conversion and transmission or regeneration of voice, images, or other data, including switching and routing apparatus 8526.91 radar apparatus, radio navigational aid apparatus and radio remote control apparatus: radio navigational aid apparatus 8532.21 other fixed capacitors: tantalum capacitors 8532.24 other fixed capacitors: ceramic dielectric, multilayer 8548.00 electrical parts of machinery or apparatus, not specified or included elsewhere in chapter 85   tier 3.a hs code hs description and representative part 8471.50 processing units other than those of subheading 8471.41 or 8471.49, whether or not containing in the same housing one or two of the following types of unit: storage units, input units, output units 8504.40 electrical transformers, static convertors (for example, rectifiers) and inductors;
