BIS Certification Consultancy for Wrought Aluminium Utensils | IS 1660:2024 | BIS & ISI Mark Certification

Updated on 31 October 2026 By Qualitance India Compliance Team

Introduction

Aluminium utensils are widely used in Indian households, restaurants, hotels, commercial kitchens, food-service operations and institutional facilities because aluminium is lightweight, economical and has good heat-conducting properties. Wrought aluminium cookware is commonly manufactured into products such as frying pans, sauce pans, tawas and other household cooking utensils.

In India, IS 1660:2024 – Wrought and Cast Aluminium Utensils – Specification (Second Revision) establishes requirements for commonly used wrought and cast aluminium utensils. BIS’s technical compendium states that the standard covers utensils up to 30 litres capacity and addresses material, thickness, shape, dimensions, manufacture, finish and product-performance requirements. The standard includes products such as utensils, thick-bottom utensils, compartmental trays and lunch boxes.

The current BIS Product Manual PM/IS 1660/4/October 2024 operates certification under Scheme-I of the BIS Conformity Assessment Regulations, 2018. It specifies a sample size of two utensils, detailed product grouping, applicable raw-material standards, testing equipment and a Scheme of Inspection and Testing.

IS 1660:2024 is included in the compulsory BIS framework for cookware and utensils. BIS’s current Scheme-I listing places it under Cookware, Utensils and Cans for Food and Beverages, and BIS’s October 2025 newsletter states that the Cookware, Utensils and Cans for Foods and Beverages (Quality Control) Order, 2025 came into force from 1 October 2025 and specifically includes IS 1660:2024 – Wrought and Cast Aluminium Utensils. BIS’s current compulsory-certification page also records subsequent 2026 QCO entries.

For manufacturers, BIS certification is therefore not simply a testing exercise. Product classification, manufacturing process, utensil type, coating, classification, size, induction-friendly base, raw-material conformity, factory testing arrangements and continuing quality control all need to be properly planned.

Qualitance India provides end-to-end BIS Certification Consultancy for Wrought Aluminium Utensils as per IS 1660:2024, including product applicability assessment, product grouping, raw-material review, sample preparation, laboratory testing coordination, documentation, BIS application assistance, factory inspection preparation and licence support.

IS 1660:2024 is titled:

“Wrought and Cast Aluminium Utensils – Specification (Second Revision)”

The current BIS Product Manual identifies certification under Scheme-I and is intended to guide BIS offices, existing licence holders and prospective applicants seeking certification.

The standard establishes requirements for commonly used wrought and cast aluminium utensils and covers important characteristics including:

Material
Sheet thickness
Shape
Dimensions
Classification
Fabrication
Handles
Workmanship
Finish
Plain finish
Anodic coating
Hard anodic coating
Non-stick coating

BIS’s technical compendium also identifies performance, thermal, free-fall and capacity tests among the tests specified to ensure reliable use of the utensils.

What are Wrought Aluminium Utensils?

Wrought aluminium utensils are cooking or food-use utensils manufactured from wrought aluminium or aluminium alloy products through mechanical working processes rather than casting the finished utensil body.

Depending on the product design, manufacturing may involve processes such as:

Blanking
Pressing
Deep drawing
Spinning
Forming
Trimming
Machining
Handle fixing
Surface treatment
Coating

The current Product Manual also covers cast aluminium utensils, meaning the certification framework for IS 1660:2024 is broader than wrought utensils alone.

BIS’s technical compendium states that the standard covers commonly used wrought and cast aluminium utensils up to 30 litres capacity.

The exact capacity, shape, diameter, size and thickness requirements depend on the particular utensil type and classification.

Manufacturers should therefore verify the applicable table, figure and dimensional provisions before finalising the BIS licence scope.

Material Requirements for Aluminium Utensils

Material quality is one of the most important aspects of aluminium utensil certification because the utensils are intended for food-related use.

BIS technical information states that aluminium used in utensils must have a minimum purity of 99.0 percent, with specified limits on impurities such as:

Iron
Silicon
Copper
Manganese

These controls support the required product quality and resistance characteristics.

The current Product Manual identifies raw-material standards depending on the component.

For the main body, applicable references include:

IS 21
IS 737
IS 617, as applicable

For other aluminium components and parts, the Product Manual identifies:

IS 21

IS 734
IS 737

as applicable.

Is BIS Certification Mandatory for Wrought Aluminium Utensils?

Yes, the product is covered by the compulsory BIS certification framework applicable to IS 1660:2024.

BIS’s current Scheme-I page specifically lists:

IS 1660:2024 – Wrought Aluminium Utensils

under Cookware, Utensils and Cans for Food and Beverages. The same page records the applicable QCO notifications through 2026.

BIS’s October 2025 newsletter states that the Cookware, Utensils and Cans for Foods and Beverages (Quality Control) Order, 2025 came into force on 1 October 2025 and lists IS 1660:2024 – Wrought and Cast Aluminium Utensils among the covered products.

Therefore, manufacturers supplying products covered by IS 1660:2024 should obtain the applicable BIS licence before using the Standard Mark and supplying regulated products in the Indian market.

Cookware, Utensils and Cans Quality Control Order

The current BIS compulsory-certification framework groups IS 1660:2024 with other cookware, utensils and food/beverage packaging standards.

The current BIS page identifies the category as:

Cookware, Utensils and Cans for Food and Beverages

and lists, among others:

Product	Indian Standard
Stainless Steel Cookware	IS 14756:2022
Wrought Aluminium Utensils	IS 1660:2024
Stainless Steel Sinks for Domestic Purposes	IS 13983:1994
Three-piece Round Open Top Metal Cans	IS 18427:2024
Aluminium Cans for Beverages	IS 14407:2023

The BIS page records the applicable QCO notifications and amendments through 2026.

Important Regulatory Update

Manufacturers should use the current regulatory position rather than older references to aluminium-utensil requirements.

The current BIS Product Manual is specifically issued for IS 1660:2024 and dated October 2024. BIS’s October 2025 newsletter states that the Cookware, Utensils and Cans QCO came into force from 1 October 2025, and the current BIS compulsory-certification page records further notifications through 2026.

The current standard is therefore IS 1660:2024, and manufacturers should align their product specifications, laboratory testing, manufacturing controls and licence scope with this edition and the latest BIS/QCO requirements.

Utensil type
Size
Classification
Sheet thickness
Coating
Induction base
Product construction

Step 2 – Manufacturing Process Identification

The manufacturer must identify whether the products are made through:

Wrought/mechanical working

Casting

The Product Manual treats these as separate grouping parameters.

Step 3 – Product Type Finalisation

The manufacturer identifies the applicable category:

Utensil
Compartmental tray
Lunch box
Thick bottom utensil
Other qualifying wrought utensil shape/dimension

Step 4 – Classification Finalisation

The product is classified as:

Light
Medium
Heavy

Step 5 – Coating Assessment

The applicable surface condition is identified:

Plain
Anodic
Hard anodic
Non-stick
Ceramic
High-temperature liquid resistant
Powder coated

Step 6 – Induction Base Assessment

Where the cookware contains an induction-friendly base, this must be identified separately because BIS grouping requires induction-compatible cookware to be tested separately.

Step 7 – Product Grouping

The licence scope and representative samples are determined according to Annex A of the current Product Manual.

Step 8 – Documentation Preparation

Technical, factory and quality-control documents are prepared.

Step 9 – Sample Preparation

The Product Manual specifies:

Sample Size: 2 utensils.

Step 10 – Laboratory Testing

Representative samples are tested for the applicable requirements of IS 1660:2024.

Step 11 – BIS Application

The manufacturer submits the BIS application with the required documents and supporting information.

Step 12 – Factory Assessment

BIS assesses the manufacturing, testing and quality-control arrangements.

Step 13 – Observation Closure

Any observations raised during assessment are addressed with corrective actions and supporting evidence.

Step 14 – BIS Licence Grant

After successful conformity assessment, BIS grants the licence for the approved scope.

Step 15 – ISI Marking

The manufacturer can apply the BIS Standard Mark to products covered by the approved licence and meeting all applicable requirements.

BIS Sample Size for Aluminium Utensils

The current BIS Product Manual specifies:

Two Utensils

as the sample size.

However, product grouping determines which sample configurations need to be tested.

For example, wrought and cast utensils are tested separately. For Groups I to III, one sample from each applicable group, coating type and classification is tested to cover the relevant size range. Group IV and Group V have their own grouping provisions.

This means manufacturers should finalise their desired product scope before sending samples to a laboratory.

Product Grouping under IS 1660:2024

Product grouping is one of the most important parts of BIS certification for aluminium utensils.

The current Product Manual identifies grouping according to:

Manufacturing Process

Wrought
Cast

Type of Utensil

Group I – Utensils

Group II – Compartmental Trays

Group III – Lunch Boxes

Group IV – Thick Bottom Utensils

Group V – Wrought Aluminium Utensils with shapes and dimensions not covered under the specified provisions.

Coating

Plain
Hard anodic
Anodic
Non-stick
Ceramic
High-temperature liquid resistant
Powder coated

Classification

Light
Medium
Heavy

Induction-Friendly Base

All of these parameters can influence the required representative samples and licence scope.

Detailed Grouping Provisions

For Groups I to III, the Product Manual provides for one sample from each applicable group, coating type and classification to cover the relevant nominal diameter/size range for that tested configuration.

For Group IV – Thick Bottom Utensils, one sample from an applicable nominal diameter/size and each coating type can cover the relevant range subject to the Product Manual provisions.

For Group V, one sample from an applicable inner diameter and coating type can cover the applicable inner-diameter range, while the shape and dimensions of each such utensil are to be declared to BIS for records.

An important provision is that where coated utensils are tested—such as hard anodic, anodic, non-stick, ceramic, high-temperature liquid-resistant or powder-coated utensils—the corresponding plain utensils of that group can also be covered, subject to the stated grouping provisions.

Cookware having an induction-friendly base must be tested separately.

Manufacturers are expected to implement a Quality Assurance Plan consisting of regular testing and in-process controls designed to ensure that products bearing the Standard Mark conform to all requirements of IS 1660:2024.

The manufacturer is expected to define:

Control unit
Testing frequency
Number of samples
In-process checks
Final tests
Recordkeeping system

The Quality Assurance Plan is submitted to the BIS Branch Office for information, and the manufacturer is expected to maintain the corresponding test records.

Control Unit for Aluminium Utensils

For guidance, the Product Manual defines the control unit as:

The quantity of utensils made by the same manufacturing process, of the same type, coating and classification, manufactured from the same sheet thickness in a day.

This means a factory producing:

The same process
Same utensil type
Same coating
Same Light/Medium/Heavy classification
Same sheet thickness

can establish its daily production as the control unit for quality monitoring.

Routine Testing Requirements

The recommended inspection framework includes controls such as:

Requirement	Recommended Control
Sheet thickness	Random check, each consignment
Material	One sample, each consignment
Fabrication	Adequate control over whole production
Shape and dimensions	One sample, each control unit
Handles	One sample, each control unit
Workmanship and finish	Adequate control over whole production
Anodic coating thickness	5% of total or minimum 5 pieces, weekly
Anodic sealing quality	2 pieces, weekly

Hard anodic abrasion resistance	One, every day
Non-stick coating thickness	5% of total or minimum 5 pieces, weekly
Non-stick corrosion resistance	2 pieces, weekly
Non-stick adhesion	One, every day
Toxic-metal limits for specified coatings	One, monthly for each coating type
Induction-compatible base	One, monthly
Nominal capacity	One, each control unit

These are the recommended levels of control provided in the current Product Manual; manufacturers must implement their submitted Quality Assurance Plan and meet all requirements of the Indian Standard.

In-House Laboratory Requirements

The Product Manual distinguishes between tests requiring in-house capability and tests that may be subcontracted.

Routine tests designated R require the relevant testing arrangement, while S identifies tests for which subcontracting is permitted. Subcontracting may be to a BIS-recognized/empanelled laboratory or another laboratory with valid NABL accreditation as per IS/ISO/IEC 17025.

For MSME manufacturers, maintaining an in-house laboratory for routine tests marked “R” is optional. MSMEs may use:

Common cluster-based facilities
Shared testing facilities
BIS-recognized/empanelled laboratories
NABL-accredited laboratories meeting the applicable requirements

For large-scale manufacturers, the Product Manual expects an in-house laboratory equipped at least for the routine tests marked “R”, along with a calibration plan. It also permits the use of shared testing facilities under the applicable BIS guidelines.

This provision can be particularly useful for smaller aluminium cookware manufacturers that do not maintain a complete testing laboratory.

Raw Material Inspection and Traceability

A manufacturer should establish a systematic incoming-material inspection system.

Important records include:

Aluminium material specification
Grade
Sheet thickness
Supplier name
Purchase documents
Material test certificate
Incoming inspection
Batch/lot number
Material traceability
Approval status

The Product Manual also provides specific raw-material references for aluminium bodies, lids, clips, wires, rivets and flame guards.

Conclusion

IS 1660:2024 – Wrought and Cast Aluminium Utensils – Specification (Second Revision) is the current Indian Standard for the covered aluminium utensil category. The standard addresses important requirements relating to material, thickness, manufacturing, dimensions, classification, handles, workmanship, finish, coatings, capacity and applicable performance characteristics.

The current BIS Product Manual PM/IS 1660/4/October 2024 operates certification under Scheme-I and specifies a sample size of two utensils. It also establishes detailed grouping based on manufacturing process, utensil type, coating, classification and induction-friendly base.

A major feature of the current framework is the wide range of product configurations that can be covered, including utensils, compartmental trays, lunch boxes, thick-bottom utensils and certain wrought utensils with other shapes and dimensions. The scope further distinguishes Light, Medium and Heavy classifications and a wide range of coatings such as plain, anodic, hard anodic, non-stick, ceramic, powder and high-temperature liquid-resistant coatings.

Raw-material conformity is also important. The Product Manual identifies applicable standards for aluminium bodies, lids, clips, rivets and other components, while BIS technical information states that aluminium used in the utensils must have a minimum purity of 99.0% with controlled impurity levels.

Testing can include sheet thickness, material, fabrication, shape and dimensions, handles, workmanship and finish, coating thickness, abrasion resistance, hardness, non-stick performance, salt-water corrosion, adhesion, toxic-metal limits, induction compatibility and nominal capacity, along with other applicable performance and thermal requirements.

The Product Manual also provides important provisions for manufacturer testing facilities. MSME manufacturers can use common cluster or shared facilities and recognized/NABL-accredited laboratories for applicable routine testing arrangements, while large manufacturers are expected to maintain suitable in-house routine-testing capability or use permitted shared facilities.

For continuing production control, the recommended control unit is based on utensils produced using the same manufacturing process, utensil type, coating, classification and sheet thickness during a day. The manufacturer must implement a Quality Assurance Plan and maintain test records.

BIS’s current compulsory-certification page lists IS 1660:2024 under the Cookware, Utensils and Cans category, while BIS’s October 2025 newsletter confirms that the relevant Cookware, Utensils and Cans for Foods and Beverages (Quality Control) Order, 2025 came into force on 1 October 2025. The current BIS page also records subsequent 2026 notifications.

Current BIS LIMS records show laboratory-specific testing charges such as ₹25,000, ₹31,000 and ₹35,000 for different listed IS 1660:2024 scopes. These are testing charges only and do not represent the complete BIS certification cost.

For manufacturers, successful BIS certification depends on correctly planning the wrought or cast process, utensil category, classification, dimensions, thickness, coating, induction base, raw materials, testing facilities, Quality Assurance Plan, documentation and licence scope before the application is submitted.
