BIS Certification for n-Butyl Acrylate (nBA) - IS 14709:1999
Mandatory ISI Mark from 10 July 2026 - Quality Control Order by Department of Chemicals & Petrochemicals | MSME Manufacturers Get Up to 80% Off on Marking Fees
This is the final confirmed deadline after a long series of extensions since 2020. No further postponement is expected.
BIS ISI Mark Certification for n-Butyl Acrylate (nBA) is mandatory in India under the Methyl Acrylate, Ethyl Acrylate and n-Butyl Acrylate (Quality Control) Order, 2020, issued by the Department of Chemicals and Petrochemicals, Ministry of Chemicals and Fertilizers. The applicable Indian Standard is IS 14709:1999 - n-Butyl Acrylate Specification. Every manufacturer or importer of n-Butyl Acrylate supplying to the Indian market must hold a valid BIS licence (CM/L Number) before 10 July 2026. n-Butyl Acrylate is almost entirely imported into India - which means the FMCS (Foreign Manufacturers Certification Scheme) route is critical for overseas suppliers. If you have not started the BIS process yet, start immediately.
What is n-Butyl Acrylate - and Why India's Paint, Adhesive & Polymer Industries Depend on It
n-Butyl Acrylate (CAS No. 141-32-2, chemical formula C₇H₁₂O₂, molecular weight 128.17 g/mol) is a reactive acrylic ester monomer produced by the esterification of acrylic acid with n-butanol. It is a colourless, mobile liquid with a characteristic pungent ester odour, a boiling point of approximately 145–148 °C, and a flash point of around 39–40 °C. n-Butyl Acrylate is one of the most strategically important acrylic monomers used in Indian manufacturing - not as a finished product, but as a critical reactive building block in polymer and co-polymer systems that underpin several major industries.

All nBA Supply
India is a major and rapidly growing consumer of n-Butyl Acrylate, driven by expanding construction, packaging, and textile finishing industries. Because domestic production capacity is very limited, the vast majority of India's n-Butyl Acrylate requirement is met through imports - primarily from manufacturers in South Korea, Taiwan, Japan, China, and the Middle East. Key end-use applications include:
- BOPP tape adhesives and pressure-sensitive adhesives (PSA) - the single largest application. nBA-based acrylic PSAs are used in packaging tapes, medical adhesives, graphic tapes, and protective films throughout India's massive e-commerce and FMCG supply chain.
- Emulsion polymers for paints and coatings - nBA is co-polymerised with other acrylates and styrene to produce acrylic latex binders used in exterior wall paints, industrial coatings, wood primers, and floor coatings. Every major Indian paint manufacturer depends on nBA supply.
- Textile binders and auxiliaries - nBA-based emulsions are used in pigment printing, nonwoven fabric bonding, and fibre sizing. India's textile industry is one of the world's largest consumers of synthetic binders.
- Leather finishing binders - soft, flexible acrylic coatings for leather surface finishing in India's footwear and leather goods sector use nBA as a core polymer building block.
- Construction chemicals - acrylic sealants, waterproofing membranes, tile adhesives, and concrete admixtures made with nBA copolymers are in high demand as India's infrastructure sector expands.
- Paper coatings - nBA-based binders improve the surface strength, printability, and ink receptivity of paper and paperboard used in packaging and publishing.
- Acrylic rubber and elastomers - specialty nBA-based rubbers are used in automotive seals, O-rings, and industrial gaskets requiring heat and oil resistance.
Why Inhibitor Control is the Critical Safety and Quality Factor for nBA: n-Butyl Acrylate is a reactive monomer - it can undergo spontaneous exothermic polymerisation if inhibitors are depleted, leading to runaway reactions, vessel rupture, and fire. IS 14709:1999 specifies strict limits on the inhibitor level (MEHQ - Monomethyl Ether of Hydroquinone) in each shipment. Too little inhibitor risks spontaneous polymerisation in storage tanks. Too much inhibitor interferes with the downstream polymerisation process, causing product quality failures in the final adhesive or coating. BIS certification under IS 14709:1999 ensures every batch of nBA arriving in India has verified, in-specification inhibitor levels - protecting both industrial safety and product quality.
QCO Timeline - Six Years of Extensions and the Final 10 July 2026 Deadline
The n-Butyl Acrylate QCO has one of the longest extension histories of any chemical QCO in India - spanning from its original 2020 notification through multiple postponements. Understanding this timeline explains why the 10 July 2026 deadline is final and why the government and BIS will not grant another extension:
Six Years of Extensions - Why There Will Not Be a Seventh
The government has extended the n-Butyl Acrylate QCO more times than almost any other chemical QCO in India. Each extension has been driven by the genuine challenge of certifying primarily overseas manufacturers through FMCS. However, BIS is now actively processing FMCS applications for nBA, licences are being granted, and the supply chain has had six years of notice. The 10 July 2026 deadline represents the absolute end of the government's patience. Foreign manufacturers who have not yet applied should file their FMCS application immediately - the FMCS process alone takes 14–20 weeks from application to licence grant.
IS 14709:1999 - What the Standard Specifies and What the Lab Tests for Each Batch
IS 14709:1999 is the Indian Standard titled "n-Butyl Acrylate - Specification", published by the Bureau of Indian Standards under Division PCD 9 (Petroleum, Coal and Related Products - Organic Chemicals). It is the primary quality standard for n-Butyl Acrylate intended for industrial use in India, specifying the exact purity, impurity limits, inhibitor levels, and analytical test methods that every compliant batch must pass. Here is a complete reference overview:

5 Key Quality Parameters Tested Under IS 14709:1999
The laboratory testing under IS 14709:1999 is precision analytical chemistry performed at a BIS-recognized NABL-accredited laboratory. Five mandatory parameters must be tested per the standard, and each has direct relevance to safety in storage and performance in downstream polymer applications:
Assay (Purity)
Primary purity test - measures the actual n-Butyl Acrylate content of the sample by gas chromatography (GC). High assay ensures consistent polymer molecular weight, glass transition temperature, and performance in adhesive, paint, and textile applications. Low assay indicates off-spec product with excess by-products, affecting downstream yields.
Minimum 99.0% (typical commercial: 99.5%+)Acidity (as Acrylic Acid)
Measures residual acrylic acid and other acidic impurities in nBA. Excess acidity causes corrosion of storage and transport equipment (tanks, valves, pumps), accelerated inhibitor depletion, and uncontrolled polymerisation side reactions. Critical for safe storage and for achieving correct polymer performance.
Maximum 0.01% w/w (as acrylic acid)Colour (Pt-Co Scale)
Visual quality indicator measured on the Platinum-Cobalt (APHA) colour scale per IS 8768. n-Butyl Acrylate should be water-white to very pale. Elevated colour (above 10 APHA) indicates degradation, contamination, or improper inhibitor management, which leads to colour problems in the finished polymer product.
Maximum 10 APHA (Pt-Co scale)Water Content (% by Mass)
Water in nBA is measured by Karl Fischer titration (IS 2362 / IS 1448 Part 182). Moisture causes hydrolysis of the ester bond, generating acrylic acid and n-butanol - directly degrading product quality, increasing acidity, and reducing shelf life. Water also inhibits emulsion polymerisation processes in downstream manufacturing.
Maximum 0.05% w/w (Karl Fischer)Inhibitors (as MEHQ)
The most safety-critical parameter. MEHQ (Monomethyl Ether of Hydroquinone) is the stabiliser added to prevent spontaneous polymerisation during storage and transport. The IS 14709:1999 standard specifies an acceptable MEHQ range - too low risks runaway polymerisation; too high impairs downstream polymer initiation efficiency and product properties.
Specified MEHQ range per IS 14709 AnnexWhy Inhibitor (MEHQ) Testing Is the Most Critical Parameter Under IS 14709:1999: n-Butyl Acrylate undergoes spontaneous, highly exothermic polymerisation if heated or if inhibitor levels drop below specification - even in ordinary storage conditions. Multiple industrial incidents worldwide have involved nBA tanks rupturing due to runaway polymerisation caused by sub-specification inhibitor levels in received product. BIS certification under IS 14709:1999 enforces verified inhibitor levels per batch - making the ISI Mark a genuine safety assurance mechanism, not merely a quality label. Indian downstream users - adhesive manufacturers, paint producers, and textile chemical plants - are legally and operationally protected when they source BIS-certified nBA.
MSME Discount on BIS Marking Fees - Up to 80% Off for Eligible Manufacturers
If your n-Butyl Acrylate manufacturing unit is registered as a Micro, Small, or Medium Enterprise under Udyam Registration, you are eligible for substantial concessions on BIS ISI Mark marking fees - the per-unit fee paid to BIS based on your annual production or sales volume.

4 Rules Every n-Butyl Acrylate Manufacturer & Importer Must Know
Manufacturer Only - Not Traders
BIS grants the ISI Mark licence only to the actual nBA producer. Indian importers, distributors, and traders cannot apply - the overseas manufacturer must apply via FMCS.
FMCS Is the Primary Route
Since India imports most of its nBA, the Foreign Manufacturers Certification Scheme applies. Overseas manufacturers need an Authorized Indian Representative (AIR) to apply.
Factory Inspection Is Mandatory
A BIS officer visits the production plant - domestically or internationally - to verify production systems, QC lab, inhibitor handling, and safety records before granting the licence.
Annual Renewal Required
ISI Mark licence for nBA is valid for 1 year. Renewal must be filed before expiry. Selling nBA under an expired BIS licence is a BIS Act violation with penalties and potential seizure.
BIS ISI Mark Certification Process for n-Butyl Acrylate - Step by Step
| Step | What Happens |
|---|---|
| STEP 1 | Appoint Authorized Indian Representative - AIR (foreign manufacturers only) - The AIR manages all BIS communication, document submission, fee payments, and factory inspection coordination on behalf of the overseas nBA manufacturer. The AIR must be an Indian-registered company. Standphill India provides this service. |
