Thermal foggers are Broadly used in India for pest control, disinfection, Pest control, agricultural and public health applications. Because these machines release chemical fog into the environment, the Bureau of Indian Standards has made it mandatory for certain categories of fogging Tools to comply with relevant safety and performance standards.
If you are planning to manufacture, import or sell thermal foggers in India, it is important to obtain a BIS certificate.
This blog explains the BIS requirements, applicable standards, eligibility, documentation and the entire certification process for thermal foggers.
What is a Thermal Fogger?
A thermal fogger is a machine that converts a liquid solution into fog/mist using heat. It uses either butane/propane gas, electric heating, or fuel-powered systems to generate high density fog.
Common uses include:
- mosquito control
- disinfection and sanitation
- agricultural spraying
- industrial fumigation
- odor control
Since the equipment interacts with chemicals and produces heat, BIS certification ensures safety, quality and consumer protection.
Is BIS Certification Mandatory for Thermal Foggers?
BIS certification becomes mandatory if the product falls under any BIS standard notified by the Ministry of Commerce & Industry.
Most electrical foggers/portable thermal foggers used for sanitation fall under:
Applicable Standard: IS 11311 – Portable Fogging Machines
This Indian Standard covers construction, performance, safety, and reliability requirements for fogging machines including:
- Thermal foggers
- ULV foggers
- Pulse-jet foggers
- Electric foggers
If your fogger is electric, fuel-based, or portable, it is likely to fall under IS 11311, making BIS certification essential.
Types of BIS Certification Applicable
Depending on the product and manufacturing setup, the following BIS schemes may apply:
1. ISI Mark Certification (Scheme-I – For Domestic Manufacturers)
For Indian manufacturers producing foggers locally. BIS conducts:
- Factory inspection
- Product testing
- Performance evaluation
- Quality system verification
On approval, BIS issues a License to use ISI mark on the fogger.
2. BIS FMCS (Foreign Manufacturer Certification Scheme)
For manufacturers located outside India who want to sell Fogging Machines in the Indian market.
3. CRS (Compulsory Registration Scheme)
If the fogger has significant electronic/electrical components, it may fall under CRS based on notification.
(CRS applies mostly to IT & electronics, but electronic foggers may be assessed.)

Steps to obtain BIS Certification for Thermal Fogger
The general BIS certificate for thermal fogger process involves the following steps:
1. Product Classification and Standard Identification
ELT experts first identify:
- Whether your fogger is electric or fuel based
- Motor/Coil Specifications
- Applicable IS Standards
It defines the certification path.
2. Factory Inspection (if ISI scheme applies)
A BIS auditor visits the manufacturing unit to check:
- quality control procedures
- quality of raw materials
- instrument calibration
- testing facilities
3. Sample testing in BIS-approved lab
Product samples are tested for:
- security
- electrical performance
- Durability
- Leakage and chemical compatibility
- heat protection
4. Submission of Online Application
The complete application has been uploaded on the BIS Standards Online Portal, which includes:
- factory document
- test report
- technical drawings
- process flow chart
5. Grant of BIS License
After verification and compliance, BIS issues:
- isi mark license
- Unique CM/L Number
After this the BIS ISI logo can be marked on the product.

Cost & Timeline for BIS Certification
Cost varies depending on:
- Product type (electric or fuel-based)
- Number of components to be tested
- Specific IS standard
- Lab test fees
Typical Estimate
- Timeline: 45–75 days
- Cost: ₹1.5–2.5 lakh (approx.) depending on complexity
Time Required for BIS Certification
Approximate Timeline: 30–60 Days
- Document preparation – 2–5 days
- BIS testing – 15–30 days
- BIS scrutiny & approval – 15–20 days
