IS 302 Part 1 Certification Timeline: From Application to ISI Mark

Manufacturers and importers asking "how long does IS 302 Part 1 BIS certification take?" need a realistic answer to plan their QCO 2026 compliance. This guide breaks down the complete timeline from decision to first certified products.

Overview: 14-22 Weeks for a Straightforward Product

The complete certification journey from decision to first ISI-marked product typically takes 14-22 weeks for a household appliance. Complex products or products with deficiencies can take longer.

Phase 1: Lab Selection and Sample Preparation (1-2 weeks)

• Select a BIS-recognized lab for IS 302 Part 1/Part 2 testing (HOT is recognized)
• Submit pre-testing documentation for lab review: product description, circuit diagram, component list, User Manual
• Prepare test samples — typically 2-3 units required
• Ship samples to the lab

Phase 2: Laboratory Testing (6-10 weeks)

IS 302 Part 1 testing is comprehensive and cannot be rushed. The test sequence follows a specific order prescribed by the standard — some tests (like aging and endurance tests) have fixed durations that cannot be compressed. Typical test duration:

• Simple products (irons, kettles): 6-8 weeks
• Moderate complexity (food processors, fans): 8-10 weeks
• Complex products (washing machines, dishwashers): 10-14 weeks

If failures occur during testing, design changes are needed and retesting adds 4-6 weeks.

Phase 3: BIS Application Preparation (1-2 weeks)

• Compile test report from the lab
• Prepare BIS application: company documents, factory details, product details, test report
• Submit application on BIS portal with application fee

Phase 4: BIS Scrutiny and Factory Inspection (4-8 weeks)

• BIS officer scrutinizes the application — may raise deficiency queries (adds 2-4 weeks each query)
• BIS grants Grant of Licence (GOL) — subject to factory inspection
• BIS factory inspector visits the manufacturing facility
• If factory inspection passes: licence granted

QCO 2026 Deadline Math

Large enterprises must be certified by 1 October 2026. Working backwards from October 2026 with a 22-week worst-case timeline means starting the process no later than April-May 2026. This is NOW. Labs will fill up before the deadline — do not wait.
