SCOMET Category 2 - Biological Agents, Toxins, and Biosecurity Export Controls

Published: April 01, 2026 | By: TariffWolf Team

SCOMET Category 2 controls the export of micro-organisms, toxins, plant pathogens, and genetically modified organisms (GMOs) that pose potential biosecurity risks. These biological agents have legitimate uses in medicine, agriculture, and research — but they can also be misused as biological weapons. India’s controls under Category 2 are aligned with the Australia Group common control lists, reflecting the country’s commitment to preventing biological weapons proliferation.

What Does Category 2 Cover?

Category 2 is divided into eight sub-categories, each targeting a specific class of biological material. The overarching principle is that an agent or pathogen is covered under Category 2 except when it is in the form of a vaccine. This vaccine exemption is one of the most important — and most commonly misunderstood — provisions in the entire SCOMET system.

Sub-category 2A: Bacteria

Sub-category 2A lists controlled bacteria (including Rickettsials), whether natural, enhanced, or modified, in the form of isolated live cultures or as material deliberately inoculated with such cultures. The list includes 39 entries covering some of the most dangerous bacterial pathogens known. Key entries include 2A001 (Bacillus anthracis — the causative agent of anthrax), 2A010 (Francisella tularensis — causing tularemia), 2A028 (Yersinia pestis — causing plague), and 2A027 (Vibrio cholerae).

Several Clostridium species are controlled, including 2A007 (Clostridium botulinum) and 2A008 (Clostridium perfringens, epsilon toxin producing types). Notably, the control on Clostridium perfringens is limited to epsilon toxin-producing strains, thereby exempting other strains used as positive control cultures for food testing and quality control.

Sub-category 2B: Fungi

Nine fungal species are controlled under 2B, including 2B001 (Blastomyces dermatitidis), 2B002 (Coccidioides immitis), and 2B003 (Histoplasma capsulatum). These are systemic fungal pathogens capable of causing severe disease in humans. The sub-category also includes agricultural pathogens like 2B008 (Bipolaris oryzae), which causes brown spot disease in rice.

Sub-category 2C: Parasites

Sixteen parasitic species are listed under 2C, including 2C009 (Plasmodium falciparum — the deadliest malaria parasite), 2C001 (Entamoeba histolytica), and several Schistosoma species. These organisms are controlled because of their potential to be weaponised as incapacitating agents.

Sub-category 2D: Viruses

Sub-category 2D contains the largest number of entries within Category 2, covering more than 50 controlled viruses. These include some of the most dangerous pathogens in the world: 2D010 (Ebolavirus — all members of the genus), 2D003 (Avian influenza virus of high pathogenicity), and Marburg virus. The list also includes regionally significant viruses such as 2D025 (Kyasanur Forest Disease virus), which is endemic to parts of India.

One important note: the Avian influenza control applies only to highly pathogenic strains as defined by the World Organisation for Animal Health (OIE), the European Union, or competent national regulatory bodies. Standard low-pathogenicity avian influenza strains are not controlled.

Sub-category 2F: Toxins

Category 2F controls 31 toxins, including 2F001 (Abrin), 2F002 (Botulinum toxins), 2F004 (Ricin), and 2F005 (Saxitoxin). These are among the most potent biological poisons known. An important exemption exists for conotoxins (2F019): pharmaceutical formulations designed for human administration in the treatment of medical conditions, pre-packaged for clinical distribution, and authorised by a state authority are excluded from control.

Sub-category 2G: Plant Pathogens

Over 30 plant pathogens are listed under 2G, reflecting the dual-use risk that agricultural bioweapons pose to food security. Entries include 2G001 (Bemisia tabaci — the whitefly vector), 2G009 (Phytophthora infestans — the potato late blight pathogen that caused the Irish Famine), and 2G013 (Magnaporthe oryzae — rice blast fungus). India-relevant pathogens such as 2G019 (Tilletia indica — Karnal bunt of wheat) are also controlled.

Sub-category 2H: Genetic Elements and GMOs

Sub-category 2H controls genetically modified organisms that contain or express genetic elements coding for pathogenicity factors of any listed agent. This is a forward-looking provision that addresses advances in synthetic biology and genetic engineering. If a GMO contains genetic material coding for virulence factors, toxin production, or immune evasion capabilities of a listed pathogen, it falls under SCOMET control — regardless of whether the host organism itself is pathogenic.

The Vaccine Exemption — Getting It Right

The vaccine exemption is the single most important qualification in Category 2: an agent or pathogen is controlled except when it is in the form of a vaccine. However, this exemption is narrower than many exporters assume. It applies only to finished, formulated, approved vaccine products — not to seed stocks, master cell banks, bulk biological substances, or reference strains. A live culture of Bacillus anthracis remains controlled under 2A001 even though anthrax vaccines exist, because the culture is not itself a vaccine.

Similarly, purified toxins such as Botulinum toxin remain controlled under 2F even though toxoid vaccines derived from them exist. The vaccine exemption addresses the product form, not the biological relationship between an agent and a vaccine made from it.

Australia Group Alignment

India became a member of the Australia Group (AG) in 2018. The AG is a multilateral export control regime focused on preventing the spread of materials, equipment, and technologies that could contribute to chemical and biological weapons programmes. Category 2 of the SCOMET list is harmonised with the AG’s common control lists for biological agents. This alignment means that Indian exporters of biological materials face similar regulatory requirements as their counterparts in other AG member states.

Equipment Controls in Category 3D

While the biological agents themselves are listed in Category 2, the equipment used to handle, process, and weaponise these agents is controlled under Category 3D. This includes cross-flow filtration equipment (3D008) capable of separating micro-organisms and toxins, spray drying equipment (3D010) capable of drying pathogens, freeze-drying equipment (3D009), and biocontainment chambers and biological safety cabinets (3D011). Exporters of laboratory and bioprocessing equipment must check Category 3D thresholds in addition to the agent-specific controls in Category 2.

What Is NOT Controlled Under Category 2?

Not every biological material requires a SCOMET licence. The following categories of items typically fall outside Category 2 controls: standard probiotics and food-grade cultures, non-pathogenic commercial strains used for industrial fermentation, standard commercial diagnostic kits using inactivated or non-viable agents, commonly available biocontrol agents used in agriculture, and approved commercial vaccines. The key test is whether the specific organism is a listed species in sub-categories 2A through 2H and whether it exists in a form (live culture, enhanced strain) that triggers control.

Practical Compliance Considerations

Exporters in the pharmaceutical, biotechnology, agricultural, and research sectors should screen all outbound shipments of biological materials against Category 2. Even academic and research institutions are subject to these controls when transferring listed agents internationally. The licensing authority for Category 2 is the DGFT, and applications are filed through the DGFT’s online Export Management System under the SCOMET scheme.

Given the sensitivity of biological agents, exporters should also be aware of the WMD Act 2005 catch-all provisions. Even if a biological material is not listed in Category 2, if the exporter has knowledge or reason to believe it will be used in connection with biological weapons, export controls are triggered under the catch-all clause.

Conclusion

SCOMET Category 2 represents India’s commitment to biosecurity and the prevention of biological weapons proliferation. The category covers a comprehensive range of pathogens, toxins, plant diseases, and genetically modified organisms — with carefully defined exemptions for vaccines and non-pathogenic commercial products. Exporters dealing with biological materials should classify their products carefully, paying particular attention to the vaccine exemption boundaries and the related equipment controls in Category 3D.
