BIS Certification for DC Supplied / Battery-Operated Foot Warmers and Heating Mats in India products are subject to mandatory BIS Compulsory Registration Scheme (CRS) requirements in India. Manufacturers and importers must obtain valid BIS CRS registration for each model before the product can be manufactured, imported, or sold in the Indian market. Non-compliance carries penalties including product seizure and prosecution under the BIS Act 2016.
This guide covers the applicable Indian Standards, mandatory safety testing, the step-by-step CRS registration process, document requirements, and the most critical compliance pitfalls for this product category in 2026.
📜 Applicable Indian Standards
The following Indian Standards apply to this product category under the BIS CRS framework:
- IS/IEC 60335-2-17 — Particular requirements for blankets, pads, sleeping bags, and similar flexible heating appliances
- IS/IEC 60335-1 — General requirements for safety of household and similar electrical appliances
- IS 13252 (Part 1) — Indian adaptation of IEC 60335-1
- IS 16046 / IEC 62133 — Safety requirements for lithium-ion battery packs (for battery-operated models)
📌 Heating appliances used in direct contact with the body — such as foot warmers and heated mats — are subject to strict surface temperature limits under IS/IEC 60335-2-17. Skin-contact temperature and thermal cut-out performance are the most scrutinised test parameters in this category.
🔬 Mandatory Safety Tests
BIS-approved laboratories evaluate the following key areas during safety testing:
Electrical Safety
Insulation resistance, dielectric strength, leakage current, earth continuity, and DC power supply safety.
Heating Element
Surface temperature limits in normal and fault conditions, thermal cut-out calibration and actuation, and element continuity.
Battery Safety
Overcharge, over-discharge, short circuit, and thermal protection for lithium-ion battery packs.
Fault Condition
Single-fault temperature rise, element short-circuit behaviour, and thermal fuse actuation verification.
📋 Step-by-Step BIS CRS Registration Process
- Standard IdentificationConfirm the product maps to IS/IEC 60335-2-17. Foot warmers with vibration or massage functionality may require concurrent multi-part standard testing.
- Appoint AIRForeign manufacturers must appoint an AIR in India to file the BIS application and hold compliance liability.
- Sample TestingSubmit production samples to a BIS-approved lab. Thermal testing for heating products typically takes 5–7 weeks due to endurance heating cycles.
- Online ApplicationSubmit Form VI, test reports, factory documents, photographs, trademark certificate, and AIR letter on BIS Manak Online portal.
- Query ResolutionCommon BIS queries involve thermal cut-out actuation data, skin-contact temperature evidence, and battery pack certification records.
- R-Number GrantBIS issues the R-number upon approval. Mark on the product, power supply, packaging, and user manual.
- RenewalValid for 2 years. Changes to heating element, thermal cut-out, or battery require re-testing.
📄 Documents Required
- Completed BIS Form VI and declaration of conformity
- Test report as per IS/IEC 60335-2-17 from BIS-approved laboratory
- Battery pack test report as per IS 16046 / IEC 62133 (for battery-operated models)
- Factory registration and address proof
- Trademark registration certificate
- AIR appointment letter (for foreign manufacturers)
- Product photographs with compliance label placement
- Technical specification sheet (rated voltage, wattage, temperature setting range)
- User manual in English and/or Hindi
☠️ Common Rejection Reasons
Common rejection causes include skin-contact surface temperatures exceeding permissible limits at higher heat settings, thermal cut-out actuation occurring outside the required temperature range, missing battery safety test documentation, and incomplete endurance cycle test data for the heating element.
🏭 Special Considerations for Importers
Foot warmers and electric heating mats imported for the Indian winter market are subject to BIS market surveillance, particularly in northern India where seasonal demand peaks. Importers must plan BIS CRS registration well ahead of the selling season, as testing timelines of 5–7 weeks mean certification cannot be rushed.
