Digital Television Receivers for Satellite Broadcast Transmission — including DTH set-top boxes, integrated satellite receivers, and hybrid OTT-satellite units — are subject to mandatory BIS ISI certification under IS 18112:2022. From 26 July 2026, no such product may be imported or sold in India without a valid BIS licence. Non-compliance attracts penalties under the BIS Act 2016.
This guide covers the applicable standard, safety and performance requirements, the certification process, and key compliance considerations for manufacturers and importers.
📜 Applicable Indian Standards
- IS 18112:2022 — Digital Television Receiver for Satellite Broadcast Transmission — Specification
- IS 13252 (Part 1) — Safety of household and similar electronic apparatus (general requirements)
- Aligned with DVB-S / DVB-S2 demodulation standards and IEC 60065 safety requirements
📌 India has over 70 million DTH subscribers. IS 18112:2022 covers both electrical safety (power supply, leakage current, insulation) and performance (signal sensitivity, demodulation, HDMI output quality) — ensuring products reliably and safely serve India's broadcast environment.
🔬 Mandatory Requirements Under IS 18112:2022
Electrical Safety
SMPS insulation resistance, dielectric strength, leakage current limits, earth continuity (Class I units), and protection against overloading and short-circuit.
RF Performance
Satellite signal reception sensitivity (C-band and Ku-band), demodulation of DVB-S and DVB-S2 streams, channel switching time, and EPG functionality.
EMC Requirements
Conducted and radiated emission limits, ESD immunity, electrical fast transient (EFT/Burst) immunity per applicable IS/CISPR limits.
AV Output Quality
HDMI output signal integrity, composite AV output levels, and audio output conformance for both SD and HD content.
📋 Step-by-Step BIS ISI Certification Process
- Model ClassificationConfirm whether the receiver is a standard STB, integrated TV-tuner, or hybrid OTT-satellite unit, as each may have distinct scope treatment under IS 18112:2022.
- Appoint AIR (for foreign manufacturers)Foreign manufacturers must appoint an Authorised Indian Representative before filing the BIS application.
- Sample TestingSubmit representative units to a BIS-recognised laboratory for safety and performance testing. Typical testing time: 5–7 weeks.
- Online ApplicationSubmit application, test report, factory documents, trademark certificate, and AIR letter on BIS Manak Online portal (manak.bis.gov.in).
- Factory InspectionBIS officers inspect the manufacturing facility for quality systems, production process, and in-house testing capability.
- Licence Grant & MarkingBIS issues the ISI Mark licence. Apply the ISI Mark to the product body, packaging, and user manual.
📄 Documents Required
- Company incorporation / registration certificate
- Product technical specification sheet (model, voltage, power, tuner frequency range)
- Circuit diagrams and block diagram of SMPS and tuner circuits
- Bill of Materials (BOM) for key components
- Trademark registration certificate
- AIR appointment letter (for foreign manufacturers)
- Product photographs showing label placement
- User manual in English and/or Hindi
⚠ Common Rejection Reasons
Common rejection causes include SMPS insulation or leakage current failures due to low-cost power supply designs, DVB-S2 sensitivity below the IS 18112:2022 minimum threshold at marginal signal levels, HDMI output signal levels outside permitted range, and EMC emission failures from inadequate PCB shielding on the LNB power supply circuit.
🏭 Special Considerations for Importers
Satellite receivers are imported in large volumes for India's DTH operators, FTTH service providers, and open-market retail. Each model variant (SD, HD, 4K) requires individual BIS ISI certification. Importers must hold valid BIS documentation for each model SKU before customs clearance.
