SCOMET Categories Explained - All 9 Categories from 0 to 8
India’s SCOMET export control list contains over 700 entries spread across 9 categories. For many exporters, simply knowing which category to look at is half the battle. This article gives you a clear, practical overview of every SCOMET category - what it covers, who controls it, and the kinds of items you will find in each.
Category 0 - Nuclear Materials, Equipment, and Technology
Licensing Authority: DAE (Department of Atomic Energy)
Category 0 covers items directly related to nuclear energy and nuclear weapons. This includes source materials like uranium and thorium, special fissile materials like plutonium, nuclear reactor components, fuel fabrication equipment, heavy water production technology, and reprocessing equipment.
Example items: Zirconium alloys with hafnium content below 2000 ppm (0A303), uranium enrichment centrifuges, nuclear-grade graphite, tritium, heavy water (deuterium oxide).
Key point: Category 0 is the only category handled entirely by DAE, not DGFT. The application process and forms are different from other categories.
Category 1 - Toxic Chemicals and Precursors
Licensing Authority: DGFT
Category 1 covers chemicals controlled under the Chemical Weapons Convention (CWC). It is divided into sub-categories aligned with CWC Schedules 1, 2, and 3, plus additional chemicals of proliferation concern. Each entry typically includes the chemical name and its CAS (Chemical Abstracts Service) number for precise identification.
Example items: Thiodiglycol (CAS 111-48-8), Phosphorus trichloride (CAS 7719-12-2), Hydrogen fluoride (CAS 7664-39-3), Dimethyl methylphosphonate (DMMP).
Key point: Chemical exporters must match both the chemical name and CAS number against the SCOMET list. Common names can be misleading - only the CAS number provides an unambiguous identification.
Category 2 - Micro-organisms, Toxins, and Related Equipment
Licensing Authority: DGFT
Category 2 covers biological agents and toxins that could be used in biological weapons, along with equipment that could be used for their production or dissemination. This category is aligned with the Biological Weapons Convention (BWC) and the Australia Group’s common control lists.
Example items: Bacillus anthracis (anthrax), Ebola virus, Botulinum toxins, Ricin, fermenters with specific capacities, aerosol inhalation chambers, genetically modified organisms containing pathogenic gene sequences (2H0019).
Key point: Even academic and research institutions sharing biological samples with foreign laboratories may trigger Category 2 controls.
Category 3 - Materials, Materials Processing Equipment, and Technology
Licensing Authority: DGFT
Category 3 covers advanced materials and their processing equipment, particularly those relevant to missile and rocket technology. This aligns with the Missile Technology Control Regime (MTCR). Items include specialised alloys, composite materials, propellants, and production equipment for these materials.
Example items: Maraging steels with specific tensile strengths (3A102), carbon fibre with specific modulus values, ammonium perchlorate rocket propellant, filament winding machines, hot isostatic presses.
Key point: Pay close attention to threshold values - many Category 3 items are controlled only when they exceed specific performance specifications (tensile strength, modulus, particle size, etc.).
Category 4 - Nuclear-Related Dual-Use Equipment and Technology
Licensing Authority: DGFT
Category 4 covers items that are not themselves nuclear materials but could be used in a nuclear programme. These are dual-use items that have legitimate civilian applications (industrial, scientific, medical) but could also contribute to nuclear weapons development. The category is aligned with the NSG Dual-Use List.
Example items: High-speed cameras above certain frame rates, flash X-ray generators, mass spectrometers, high-voltage power supplies, specialised vacuum pumps, numerical control equipment for specific tolerances.
Key point: Category 4 frequently overlaps with Category 0. The Commodity Identification Notes provide override rules - when in doubt, the nuclear-specific category (0) takes precedence.
Category 5 - Aerospace Systems and Equipment
Licensing Authority: DGFT
Category 5 covers aerospace systems, navigation equipment, avionics, and related technologies. This includes unmanned aerial vehicles (UAVs), rocket systems, guidance and control equipment, and space-launch technology. The category is aligned with both the MTCR and Wassenaar Arrangement.
Example items: Complete rocket systems with range/payload exceeding MTCR thresholds, inertial navigation systems, GPS jamming equipment, re-entry vehicle technology, thrust vector control systems.
Key point: India’s growing drone industry should pay particular attention to this category. UAVs capable of carrying specific payload weights over specified ranges may be controlled.
Category 6 - Munitions List
Licensing Authority: DDP (Department of Defence Production, Ministry of Defence)
Category 6 is India’s munitions list covering conventional arms and military equipment. Unlike other categories handled by DGFT, Category 6 falls under the Ministry of Defence. It covers firearms, ammunition, military vehicles, explosives, armoured protection, military training equipment, and military-grade imaging systems.
Example items: Automatic weapons and their components, military explosives, tanks and armoured vehicles, military aircraft and components, naval vessels designed for combat, body armour above specified protection levels.
Key point: Category 6 uses a completely different licensing process through DDP. Applications do not go through the DGFT portal. Indian defence manufacturers under Make in India must be especially vigilant about this category.
Category 7 - Electronics, Computers, and Information Security
Licensing Authority: DGFT
Category 7 covers advanced electronics, high-performance computing equipment, and information security systems including encryption technology. This category is particularly relevant for India’s IT sector, as it controls certain types of cryptographic hardware and software.
Example items: Telecommunications interception equipment, high-performance signal processing equipment, radiation-hardened electronics, information security systems employing cryptographic techniques beyond specified thresholds.
Key point: Indian software companies exporting products with encryption functionality should check Category 7 carefully. Mass-market exemptions may apply, but they have specific conditions.
Category 8 - Marine and Submarine Technologies
Licensing Authority: DGFT
Category 8 covers marine technologies, underwater systems, and naval propulsion equipment. This includes submarines and their components, underwater detection systems, diving and underwater swimming equipment beyond certain depth ratings, and marine acoustic systems.
Example items: Submarine hull sections, sonar systems, autonomous underwater vehicles (AUVs), closed-circuit diving apparatus, underwater communications equipment, naval nuclear propulsion technology.
Key point: With India’s growing shipbuilding and naval defence industry, Category 8 is becoming increasingly relevant for domestic manufacturers seeking export orders.
How to Use This Guide
Start by identifying which category your product most likely falls under based on its function and application. Then check the specific entries within that category against your item’s technical specifications. Remember that some items may appear in multiple categories - cross-category checks are essential.
