BIS Certification Consultancy for n-Butyl Acrylate | IS 14709:1999 | BIS & ISI Mark Certification

Introduction

n-Butyl Acrylate is an important acrylic ester used as a raw material in the manufacture of paints, coatings, adhesives, sealants, printing inks and various polymer products. Because its purity, acidity, colour, moisture and inhibitor content can directly influence downstream processing and product quality, controlling its specification is important for chemical manufacturers, importers and industrial users.

In India, IS 14709:1999 – n-Butyl Acrylate – Specification prescribed requirements for this chemical, including limits for assay, acidity, colour, water content and inhibitors, along with requirements for packing and marking. BIS's technical information identifies n-Butyl Acrylate as a clear, colourless liquid and notes that it is flammable and harmful if inhaled or in contact with skin.

However, there is an important regulatory update for businesses planning certification today: BIS revised the standard to IS 14709:2025, and its implementation circular states that IS 14709:1999 was withdrawn on 27 September 2025.

For the existing QCO framework, BIS's current Scheme-I page continues to list IS 14709:1999 and shows 2026 amendments to the n-Butyl Acrylate Quality Control Order. BIS's current "Upcoming QCOs" page also lists n-Butyl Acrylate against IS 14709:1999 with an enforcement date of 31 July 2026.

Therefore, manufacturers and importers should carefully review the latest BIS notification, applicable QCO and current standard transition requirements before applying.

Qualitance India provides BIS Certification Consultancy and regulatory support for n-Butyl Acrylate, including applicability review, standard transition assessment, documentation, testing coordination, BIS application support and compliance guidance.

What is IS 14709:1999?

IS 14709:1999 is titled:

“n-Butyl Acrylate – Specification”

The BIS Product Manual PM/14709/2 dated December 2022 was prepared for certification under Scheme-I of the BIS Conformity Assessment Regulations, 2018 and incorporated two amendments to the 1999 standard.

Under that Product Manual, the principal specification requirements included:

Assay
Acidity as acrylic acid
Colour
Water content
Inhibitor content
Packing
Marking

The 2022 amendment guidance clarified that either Annex A or Annex C could be used for inhibitor testing, with Annex A as the referee method.

Important Update: IS 14709:1999 Revised to IS 14709:2025

Manufacturers should not use the old 1999 standard without checking the current regulatory position.

BIS issued implementation guidelines in August 2025 stating that:

IS 14709:1999 was revised to IS 14709:2025
The withdrawal date of IS 14709:1999 was 27 September 2025
The revised standard is titled n-Butyl Acrylate – Specification (First Revision)

The revised standard introduced changes including:

Addition of IS 1448 (Part 182) as an alternate and referee method for water-content determination
Editorial correction of the inhibitor terminology from Butyl Etherhydroquinone to Monomethyl Ether of Hydroquinone (MEHQ)

The current BIS Product Manual for IS 14709:2025 gives a sample quantity of 1000 ml and states that there is no specific raw-material requirement and no grouping requirement.

This update is highly relevant for any business currently planning n-Butyl Acrylate BIS certification.

What is n-Butyl Acrylate?

n-Butyl Acrylate is an acrylic ester with the chemical formula:

CH₂=CHCOO(CH₂)₃CH₃

BIS's technical summary describes it as a clear, colourless liquid with a fruity, strong odour. It is an important acrylic ester monomer used in polymers and chemical formulations.

It is widely used as a chemical intermediate and monomer in industrial manufacturing.

Applications of n-Butyl Acrylate

n-Butyl Acrylate is used in the manufacture of:

Paints
Coatings
Adhesives
Sealants
Printing inks
Polymer emulsions
Thermoplastic ethylene-acrylate copolymers
Acrylic resins
Other polymer products

BIS specifically identifies paints and coatings, adhesives and sealants, printing inks and thermoplastic ethylene-acrylate copolymers among its application areas.

Why Quality Control of n-Butyl Acrylate is Important

For industrial chemical users, consistent n-Butyl Acrylate quality is important because impurities and deviations in concentration can affect polymerisation and downstream product performance.

The standard therefore controls parameters such as:

Assay
Acidity
Colour
Water
Inhibitor

These parameters help control purity and important chemical characteristics of the product.

Is BIS Certification Mandatory for n-Butyl Acrylate?

n-Butyl Acrylate is covered by the n-Butyl Acrylate Quality Control Order framework.

BIS's current Scheme-I listing identifies:

IS 14709:1999 – n-Butyl Acrylate

under the n-Butyl Acrylate QCO framework and also lists subsequent 2026 amendments.

The BIS "Upcoming QCOs" page currently lists:

n-Butyl Acrylate – IS 14709:1999 – Enforcement Date: 31 July 2026.

At the same time, BIS has withdrawn IS 14709:1999 and replaced it with IS 14709:2025.

Because these regulatory documents concern different stages of the standard/QCO transition, businesses should verify the latest applicable QCO notification and BIS implementation position before placing the product on the market.

n-Butyl Acrylate Quality Control Order

The n-Butyl Acrylate QCO was originally issued by the Department of Chemicals and Petrochemicals.

BIS's current Scheme-I listing records the principal n-Butyl Acrylate (Quality Control) Order, 2021 along with subsequent amendments, including:

Amendment orders in 2022
2023 amendment
S.O. 1854(E), dated 10 April 2026
S.O. 3729(E), dated 9 July 2026

The April 2026 amendment temporarily suspended conformity to the Indian Standard from 10 April 2026 to 10 July 2026 in view of supply-chain disruption.

The current regulatory framework should therefore be checked immediately before manufacturing, importing or selling the product.

BIS Certification for n-Butyl Acrylate

BIS certification for n-Butyl Acrylate is operated through the BIS product certification framework.

The 2022 Product Manual for IS 14709:1999 states that certification is operated under:

Scheme-I of the BIS Conformity Assessment Regulations, 2018.

For the revised standard, BIS has also issued a new Product Manual for IS 14709:2025 under Scheme-I.

This means manufacturers need to determine whether their certification application should be based on the current IS 14709:2025 framework rather than the withdrawn 1999 edition.

Who Needs BIS Certification for n-Butyl Acrylate?

The compliance framework is relevant to businesses such as:

n-Butyl Acrylate Manufacturers
Acrylic Monomer Manufacturers
Chemical Manufacturers
Petrochemical Manufacturers
Acrylic Resin Manufacturers
Polymer Manufacturers
Chemical Importers
Industrial Chemical Suppliers
Chemical Trading Companies
OEM and Industrial Chemical Producers

Whether a particular entity is required to hold BIS certification depends on the applicable QCO, product status and current regulatory notifications.

BIS Certification Eligibility Requirements

A manufacturer seeking certification should have suitable production and quality-control arrangements.

Depending on the manufacturing setup, these may include:

Chemical manufacturing facility
Storage tanks
Filling facility
Sampling arrangements
Laboratory
Gas chromatograph
Karl Fischer titrator
Colour testing equipment
Chemical-analysis equipment
Weighing balance
Volumetric glassware
Calibrated instruments
Qualified laboratory personnel
Quality-control procedures
Batch traceability
Packing and marking arrangements

The exact equipment should be confirmed against the current Product Manual applicable to the certification application.

BIS Certification Process for n-Butyl Acrylate

Step 1 – Regulatory Applicability Review

Before testing, determine:

Whether the product falls under the current QCO
Whether IS 14709:1999 or IS 14709:2025 applies to the transaction
Whether any exemption or temporary suspension applies
Whether the applicant requires a BIS licence

Because the standard has undergone a revision, this review is particularly important.

Step 2 – Product Specification Review

The applicable product specification is assessed, including:

Assay
Acidity
Colour
Water
Inhibitor

Step 3 – Standard Version Confirmation

The manufacturer should confirm the applicable current standard and transition requirements with BIS.

Step 4 – Documentation Preparation

Technical, factory and quality-control documents are prepared.

Step 5 – Sample Preparation

For the earlier IS 14709:1999 Product Manual, the specified sample quantity was:

1000 ml.

The revised IS 14709:2025 Product Manual also specifies:

1000 ml.

Step 6 – Laboratory Testing

Samples are tested for the applicable requirements.

Step 7 – BIS Application

The manufacturer submits the application and required documents according to the applicable BIS framework.

Step 8 – Factory Assessment

BIS assesses the manufacturing, laboratory and quality-control arrangements where applicable.

Step 9 – Observation Closure

Any observations raised during the certification process are addressed.

Step 10 – BIS Licence Grant

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

Step 11 – Packing and Marking

The manufacturer follows the applicable BIS marking and packing requirements.

Testing Requirements for n-Butyl Acrylate

The standard controls key chemical characteristics.

For the 1999 edition, BIS's technical summary identifies:

Minimum assay
Maximum acidity
Maximum colour
Maximum water
Maximum inhibitor content

The 2022 Product Manual identifies the same principal test categories.

Assay

Assay determines the concentration or purity of n-Butyl Acrylate.

The earlier Product Manual specifies a suitable gas-liquid chromatograph with flame ionization detector (FID) for assay determination.

Accurate assay testing is important because significant variation in purity can affect downstream polymerisation and formulation.

Acidity

Acidity is controlled to limit the presence of acidic impurities such as acrylic acid.

The 2022 Product Manual identifies equipment including:

Weighing balance
Measuring cylinder
Erlenmeyer flask
Burette
Pipettes
Phenolphthalein indicator
Sodium hydroxide

for acidity determination.

Colour

Colour is an important product-quality parameter for n-Butyl Acrylate.

The Product Manual identifies colour comparison equipment and a spectrophotometer for determining colour on the Pt-Co scale.

A consistent colour specification is useful for chemical-product quality control.

Water Content

Water content must be controlled because moisture can influence downstream chemical processing.

Under the 1999 framework, the Product Manual refers to IS 2362 and identifies a Karl Fischer titrator.

For the revised IS 14709:2025, BIS added IS 1448 (Part 182) as an alternate method and specified it as the referee method.

Inhibitor Content

Inhibitor content is important for controlling unwanted polymerisation during storage and handling.

Under the 1999 standard, the inhibitor requirement was tested through either:

Annex A – Gas chromatography with FID
Annex C – Spectrophotometric method

The 2022 amendment clarified that Annex A is the referee method.

The revised standard also updated the terminology of the inhibitor to Monomethyl Ether of Hydroquinone (MEHQ).

Important Safety Characteristics

n-Butyl Acrylate requires careful handling because BIS's technical summary identifies it as:

Flammable
Irritating to eyes
Irritating to skin
Harmful if inhaled
Harmful through skin contact

Manufacturers and handlers should therefore maintain appropriate chemical-safety, storage and handling procedures in addition to BIS product conformity.

Raw Material Requirements

The IS 14709:1999 Product Manual states:

Raw material: No specific requirement.

The revised IS 14709:2025 Product Manual also states:

No specific requirement for raw material.

Even so, manufacturers should maintain adequate control over:

Feedstock specifications
Supplier records
Batch identification
Production records
Chemical analysis
Traceability

Product Grouping

The 1999 Product Manual states:

Grouping guidelines: NA.

The 2025 Product Manual likewise identifies:

Grouping guidelines: NA.

Therefore, manufacturers should focus on the actual product specification, testing and approved licence scope rather than assuming that multiple variants can be automatically grouped.

Testing Equipment for IS 14709

The 1999 Product Manual identifies major equipment including:

Assay

Gas-liquid chromatograph
Flame ionization detector
Calibration standards

Acidity

Weighing balance
Measuring cylinder
Erlenmeyer flask
Burette
Pipettes
Chemical reagents

Colour

Colour comparison tubes
Colour comparator
Spectrophotometer
Pt-Co reference solutions

Water

Karl Fischer titrator
Required reagents and solvents

Inhibitor

Gas chromatograph with FID or
Spectrophotometer
Precision balance
Volumetric flasks
Pipettes
Required reagents

BIS notes that this equipment list is indicative and not exhaustive.

For bulk transportation through tank cars, tank trucks or container ships, the Standard Mark and licence number were to be incorporated on the accompanying test certificate.

Packing and Marking Requirements

Packing and marking are particularly important for bulk chemicals.

Under the 1999 Product Manual, containers were required to carry:

BIS Standard Mark
BIS Licence Number
BIS website details

The Product Manual also specified the use of an accompanying test certificate for bulk transportation modes such as tank cars, tank trucks and container ships.

The exact marking requirements for current certification should be confirmed against IS 14709:2025, its current Product Manual and the applicable BIS licence schedule.

Test Certificate

A test certificate is important for demonstrating product conformity.

For bulk supplies, the earlier Product Manual required the certificate to accompany the transport container and include the applicable Standard Mark and BIS licence information.

Manufacturers should maintain complete records linking:

Batch number
Production date
Test results
Quantity
Packing details
Customer/consignment details

Documents Required for BIS Certification

Typical documents may include:

Company registration documents
Factory address proof

Failure to review the transition from IS 14709:1999 to IS 14709:2025
Incorrect product specification
Inadequate laboratory facilities
Assay failure
Acidity failure
Colour failure
Water-content failure
Inhibitor-content failure
Incorrect test method
Missing calibration records
Incomplete batch traceability
Improper packing
Incorrect marking
Incomplete documentation
Factory not ready for assessment
Regulatory/QCO applicability confusion

The standard transition is especially important because BIS formally withdrew IS 14709:1999 on 27 September 2025.

BIS Certification Cost for n-Butyl Acrylate

There is no single fixed BIS certification cost applicable to every applicant.

The overall cost can depend on:

BIS application fees
Laboratory testing
Product testing scope
Factory assessment
Laboratory equipment
Calibration
Documentation
Retesting
Regulatory consultancy
Other compliance expenses

Current BIS LIMS information shows a listed testing charge of ₹10,500 for IS 14709:1999 at one laboratory entry.

Current BIS LIMS also lists IS 14709:2025 with a testing charge of ₹10,000 at another laboratory entry.

These are laboratory-specific charges and not the complete BIS certification cost.

Because the applicable standard has changed, applicants should confirm the current laboratory quotation for the standard and testing scope that applies to their certification.

BIS Certification Timeline

The certification timeline depends on:

Regulatory applicability
Current standard version
Documentation readiness
Sample availability
Laboratory testing
Test results
BIS application scrutiny
Factory readiness

Conclusion

n-Butyl Acrylate is an important industrial chemical used in paints, coatings, adhesives, sealants, printing inks and acrylic polymer applications. Under the earlier framework, IS 14709:1999 – n-Butyl Acrylate – Specification specified requirements for assay, acidity, colour, water content and inhibitors, together with packing and marking requirements.

For businesses dealing with this product today, the most important point is the transition in the Indian Standard. BIS revised IS 14709:1999 to IS 14709:2025 and officially stated that the 1999 edition was withdrawn on 27 September 2025.

The revised BIS Product Manual for IS 14709:2025 is also operated under Scheme-I, specifies a 1000 ml sample quantity, and states that there is no specific raw-material or product-grouping requirement.

The revised standard introduced important technical changes, including the addition of IS 1448 (Part 182) as an alternate and referee method for water-content determination and updated terminology for the inhibitor to Monomethyl Ether of Hydroquinone (MEHQ).

At the regulatory level, BIS's current Scheme-I page records amendments to the n-Butyl Acrylate QCO through 2026, while its current Upcoming QCO page lists 31 July 2026 as an enforcement date against IS 14709:1999. Because the standard and QCO transition documents overlap, manufacturers and importers should verify the latest applicable notification before relying on any particular version for current transactions.

Current BIS LIMS data shows laboratory-specific testing charges of ₹10,500 for an IS 14709:1999 entry and ₹10,000 for an IS 14709:2025 entry at the referenced laboratories. These figures are laboratory testing charges only and should not be considered the complete BIS certification cost.

For a manufacturer, successful compliance depends on correctly identifying the current applicable standard, QCO status, product specification, testing method, laboratory capability, documentation, batch traceability, packing and marking requirements.
