BIS Scheme X Certification for Compressors: A Complete Guide

 

Introduction

In India, product safety and quality standards are regulated by the Bureau of Indian Standards (BIS). For manufacturers of compressors—whether used in refrigeration, air conditioning, or industrial processes—obtaining BIS Scheme X Certification is not just a regulatory requirement but also a mark of trust, quality, and safety.

This certification assures customers and stakeholders that compressors meet Indian safety standards, perform efficiently, and comply with environmental norms. In this blog, we will explain what BIS Scheme X certification is, why it is important for compressors, eligibility criteria, the application process, benefits, and compliance requirements.

What is BIS Scheme X Certification?

The Bureau of Indian Standards (BIS) operates various certification schemes under the BIS Act, 2016. One of the most relevant for industrial and electrical products is Scheme X, which covers Mandatory BIS Certification for certain imported and domestically manufactured products.

Compressors fall under the category of products that must comply with Indian Standard (IS) specifications before they can be sold in the Indian market. The certification ensures that compressors adhere to IS 5456, IS 6595, IS 13947, and other applicable standards, depending on the type and application of the compressor.

Why is BIS Scheme X Certification Important for Compressors?

Compressors are widely used in industries like HVAC, automotive, manufacturing, and refrigeration. Ensuring their safety and efficiency is crucial. Here’s why BIS certification is essential:

  • ✅ Legal Requirement – Compressors listed under compulsory BIS certification cannot be sold without approval.

  • ✅ Consumer Safety – Ensures protection from hazards like overheating, leakage, or explosion.

  • ✅ Product Reliability – Confirms performance consistency and durability.

  • ✅ Market Access – BIS-certified compressors can be freely imported, sold, and distributed in India.

  • ✅ Brand Reputation – A BIS mark enhances trust, credibility, and competitiveness.

Types of Compressors Covered Under BIS Scheme X

The following types of compressors generally fall under mandatory certification:

  1. Refrigeration Compressors – Used in refrigerators, freezers, and HVAC systems.

  2. Air Compressors – Industrial and domestic air compressors for pneumatic tools and machinery.

  3. Rotary & Reciprocating Compressors – Commonly used in industrial setups.

  4. Hermetically Sealed Compressors – Widely used in refrigeration appliances.

Each type must comply with the relevant Indian Standards (IS) before certification.

Eligibility Criteria for BIS Certification of Compressors

Any manufacturer—domestic or foreign—intending to sell compressors in India must apply for BIS certification. Key eligibility points include:

  • The product must conform to Indian Standards.

  • The manufacturer must have a testing facility (in-house or third-party lab recognized by BIS).

  • Foreign manufacturers must appoint an Authorized Indian Representative (AIR).

  • The manufacturing unit must comply with quality control and production standards set by BIS.

Step-by-Step Process of Obtaining BIS Scheme X Certification for Compressors

Here is a simplified process flow:

Step 1: Identify Applicable Indian Standards

Determine which IS standard applies to your compressor type. For example:

  • IS 5456 – Refrigeration compressors

  • IS 6595 – Reciprocating air compressors

  • IS 13947 – Safety aspects

Step 2: Application Submission

Submit the BIS application online along with required details such as:

  • Manufacturing details

  • Product specifications

  • Test reports

  • Quality documents

Step 3: Sample Testing

Compressors are tested in BIS-recognized laboratories for compliance with safety, performance, and efficiency standards.

Step 4: Factory Inspection

BIS officials may conduct a factory audit to verify production processes, quality control measures, and testing capabilities.

Step 5: Grant of License

Once testing and inspection are successful, BIS issues a license under Scheme X. The manufacturer can then affix the ISI mark on the certified compressors.

Documents Required for BIS Certification of Compressors

Some key documents include:

  • Application form with product details

  • Test reports from BIS-recognized labs

  • Factory license and manufacturing documents

  • Quality control manual

  • Flow chart of production process

  • Trademark registration (if any)

  • Authorized Indian Representative (AIR) details (for foreign manufacturers)

Timeline & Cost of BIS Certification

  • Timeline – Usually 30–90 days, depending on product testing and documentation.

  • Cost – Involves application fee, testing charges, inspection fee, and annual license fee. The exact cost varies based on the compressor type and testing requirements.

Benefits of BIS Scheme X Certification for Compressor Manufacturers

  1. Regulatory Compliance – Meet Indian government requirements.

  2. Consumer Confidence – Gain trust through safety and quality assurance.

  3. Market Growth – Access both government tenders and private sector opportunities.

  4. Global Acceptance – BIS certification improves export potential.

  5. Reduced Risks – Minimize chances of product recalls, penalties, or bans.

Consequences of Non-Compliance

Selling or importing compressors in India without BIS certification can lead to:

  • Heavy penalties and fines.

  • Product seizure by authorities.

  • Ban on manufacturing or importing non-compliant compressors.

  • Reputation damage for the brand.

How to Ensure Smooth BIS Certification?

  • Engage with a BIS consultant for hassle-free documentation and application.

  • Ensure products are pre-tested before submission.

  • Maintain a robust in-house quality control system.

  • Stay updated with BIS notifications and amendments.

Conclusion

The BIS Scheme X Certification for Compressors is more than just a legal formality—it is a gateway to trust, quality assurance, and long-term success in the Indian market. By ensuring compliance with BIS standards, manufacturers not only meet government regulations but also position themselves as reliable, customer-focused brands.

For compressor manufacturers, obtaining BIS certification is an investment in safety, credibility, and market growth. With the right guidance and preparation, the process can be completed smoothly, ensuring that your compressors reach Indian customers with the seal of quality—the ISI mark.
