Export Control Classification Numbers (ECCN): 2B352
 P3 or P4 (BL3, BL4, L3, L4) containment levels are as specified in the WHO Laboratory Biosafety Manual (3rd editions, Geneva, 2004)
 Fermenters include bioreactors, chemostats, and continuous-flow systems.
 Centrifugal separators include decanters
 In this ECCN, “sterilized” denotes the elimination of all viable microbes from the equipment through the use of either physical (e.g., steam) or chemical agents. “Disinfected” denotes the destruction of potential microbial infectivity in the equipment through the use of chemical agents with a germicidal effect. “Disinfection” and “sterilization” are distinct from “sanitization”, the latter referring to cleaning procedures designed to lower the microbial content of equipment without necessarily achieving elimination of all microbial infectivity or viability
 Does not control reverse osmosis equipment, as specified by the manufacturer
 This entry does not control suits designed to be worn with self-contained breathing apparatus
 1. “Aerosol generating units” are devices specially designed or modified for fitting to aircraft and include nozzles, rotary drum atomizers and similar devices.
2. This ECCN does not control spraying or fogging systems and components, as specified in 2B352.h, that are demonstrated not to be capable of delivering biological agents in the form of infectious aerosols
3. Droplet size for spray equipment or nozzles specially designed for use on aircraft or “UAVs” should be measured using either of the following methods (pending the adoption of internationally accepted standards):
a. Doppler laser method
b. Forward laser diffraction method
