What is the Difference Between a BIS Standard and a QCO?

What is a BIS standard?

An Indian Standard (IS Code) is a technical document formulated by the BIS. It specifies what a product must be, its composition, dimensions, performance thresholds under test conditions and the methods by which compliance is assessed. Each IS code, for example, IS 302 for household electrical appliances, IS 694 for PVC insulated cables or IS 9873 for toy safety is the definitive technical rulebook for that product category.

BIS has formulated approximately 23,000 Indian Standards across fourteen sectors including chemicals, electronics, construction, food, textiles and automotive. Many are aligned with ISO (International Organization for Standardization) and IEC (International Electrotechnical Commission) benchmarks, meaning that conformance to an Indian Standard demonstrates compliance with an internationally recognised quality level.

By default, Indian Standards are voluntary. A manufacturer may choose to seek BIS certification against the applicable IS code and earn the ISI mark as a market signal. The decision carries no legal consequence in either direction unless a Quality Control Order has been issued for that product category.

What is a quality control order?

A Quality Control Order is issued by a Ministry of the Central Government under Section 16 of the BIS Act, 2016. A Quality Control Order (QCO) identifies specific categories of products and links them to their relevant IS codes. It designates an authorized certification body, such as the BIS, and establishes a definitive date for enforcement. From that date, no unit of the product may be manufactured, imported, sold or stored in India without a valid BIS license regardless of whether the product is made domestically or imported, and regardless of market tier or volume.

Multiple ministries issue QCOs within their respective domains. The Ministry of Heavy Industries covers machinery and electrical equipment, the Ministry of Steel covers steel products, The Ministry of Electronics and Information Technology covers electronics and IT products. DPIIT under the Ministry of Commerce covers a broad range of consumer and industrial goods. BIS administers certification across all of them under a unified scheme framework.

A product may fall under multiple IS codes depending on its specification or intended use. Where a QCO is issued for such a product, it specifies which standards apply and conformance must be demonstrated against each. This is particularly relevant in steel and chemical products, where multiple grades carry distinct IS numbers.

Note: The relevant question for any manufacturer, importer, or trader is not whether an IS code exists for the product (one almost certainly does) but whether a QCO has been notified against it or not. If a QCO is in force, certification is a legal condition of market access and customs enforcement is active without which the certification is voluntary.

Implications for businesses

For businesses whose products are not currently subject to a QCO, voluntary certification against the applicable IS code is a commercially rational preparation. If a QCO is subsequently notified for that category, a certified manufacturer would face no disruption at the enforcement date whereas the uncertified competitors must obtain certification before they can continue to supply the market. The certification process takes time and initiating it proactively preserves continuity that reactive compliance cannot.

For businesses operating on the assumption that no QCO applies to their product, that assumption requires active verification and a mere inference from prior experience would not do. QCOs are notified through the Gazette of India and such notifications do not always receive broad commercial attention. A product category that carried no mandatory requirement at the time of a previous review may have been brought within mandatory scope since. A shipment ordered before a QCO enforcement date and arriving after it is non-compliant.

Legality and risks

The list of QCO notified products is updated continuously. A compliance review based on a summary or a third-party list from several months prior instead of the current Gazette notification may not reflect the current regulatory position.

The second risk is an IS version mismatch. BIS revises Indian Standards periodically. When a standard is revised, the IS number remains the same but the version changes and the BIS licence issued against an earlier version must be formally amended to reflect the current version. A product that passes the licence number check at customs may fail a BIS market surveillance test because BIS tests it against the current version of the standard and not the version in force at the time the licence was issued causing a latent non-compliance risk.
