n-Butyl Acrylate is subject to mandatory BIS ISI certification under the Quality Control Order notified by the Government of India. From 10 July 2026, no n-Butyl Acrylate may be manufactured for sale, imported, or distributed in India without a valid BIS ISI licence under IS 14709:1999. Non-compliance attracts penalties including product seizure, market withdrawal, and prosecution under the BIS Act 2016.
This guide covers the applicable Indian Standard, key quality parameters, the certification process, documentary requirements, and critical compliance considerations for n-Butyl Acrylate manufacturers and importers.
📜 Applicable Indian Standard
- IS 14709:1999 — n-Butyl Acrylate — Specification (primary standard)
- Aligned with international acrylic monomer trade specifications (ICCA and regional industry standards)
📌 n-Butyl acrylate (butyl 2-propenoate) is a reactive acrylic monomer — a critical raw material for emulsion polymers used in paints, coatings, pressure-sensitive adhesives, sealants, and textile finishes. Its reactive nature (polymerisation hazard) makes inhibitor content and purity especially important parameters under IS 14709:1999.
🔬 Key Quality Requirements Under IS 14709:1999
Physical Properties
Appearance (colourless, clear liquid), relative density at 20°C, boiling point range, and refractive index at 20°C confirming identity and purity.
Purity & Acidity
n-Butyl acrylate assay (minimum %) and acidity as acrylic acid (maximum) — excess acidity causes reactor fouling and product quality issues in downstream polymerisation.
Inhibitor (MEHQ) Content
Monomethyl ether hydroquinone (MEHQ) content — defined minimum and maximum range. Too little causes premature polymerisation; too much affects downstream catalyst systems.
Water & Colour
Maximum water content and maximum APHA colour — indicators of storage quality and potential hydrolysis. Residue on evaporation confirms absence of non-volatile contaminants.
📋 Step-by-Step BIS ISI Certification Process
- Scope ConfirmationConfirm the n-Butyl Acrylate grade (inhibited, technical) falls within IS 14709:1999 scope. Both inhibited and uninhibited grades must meet purity parameters.
- Application FilingSubmit online on manak.bis.gov.in. Indian manufacturers use Product Certification Scheme; foreign manufacturers apply via FMCS with an appointed AIR.
- Sample TestingSubmit representative samples (with MEHQ inhibitor at specified level) to a BIS-recognised laboratory. Testing timeline: 3–5 weeks.
- Factory InspectionBIS inspects the facility for process safety controls, inhibitor dosing systems, storage conditions, and batch traceability.
- Licence GrantBIS issues the ISI Mark licence upon satisfactory test results and inspection.
- Surveillance & RenewalOngoing market surveillance; each batch must be accompanied by a CoA referencing IS 14709:1999 and the BIS licence number.
