n-Butyl Acrylate BIS QCO Suspension Extended Till 31 July 2026: What Manufacturers and Importers Must Know

• Suspension of the n-Butyl Acrylate QCO, 2021 extended from 10th July 2026 to 31st July 2026 via S.O. 3729(E).
• BIS (ISI mark) certification under IS 14709:1999 is not mandatorily enforceable for n-Butyl Acrylate BIS Certification during the suspension period.
• Change made under Section 16 read with Section 25(3) of the BIS Act, 2016, after consultation with the Bureau of Indian Standards.
• This is the latest in a series of extensions; the order was previously amended on 10th April 2026, and businesses should watch for further updates before 31st July 2026.

Introduction

The Central Government has extended the suspension of the n-Butyl Acrylate (Quality Control) Order, 2021 from 10th July 2026 to 31st July 2026, via notification S.O. 3729(E) dated 9th July 2026. This means mandatory BIS (ISI mark) certification under IS 14709:1999 remains temporarily on hold, and manufacturers, importers, and traders can continue to deal in n-Butyl Acrylate without a BIS license during this window.

The relief was granted by the Ministry of Chemicals and Fertilizers to ease global supply chain disruption. Businesses should still track the next notification closely, since the suspension could end, extend further, or be made permanent.

What Has Changed: The 9th July 2026 Notification Explained

On 9th July 2026, the Ministry of Chemicals and Fertilizers (Department of Chemicals and Petrochemicals) issued notification S.O. 3729(E), published in the Gazette of India, Part II, Section 3, Sub-section (ii). The notification amends the n-Butyl Acrylate (Quality Control) Order, 2021, which was originally notified vide S.O. 5438(E) dated 24th December 2021.

The amendment is narrow but important for compliance teams: in paragraph 2 of the 2021 Order, the proviso date ‘10th July, 2026’ has been substituted with ‘31st July, 2026’. In effect, the temporary suspension of the Order — and with it, the mandatory BIS certification requirement for n-Butyl Acrylate — now runs three additional weeks.

The notification was signed by Dr. G. Venkatesh, Joint Secretary, under file number PC-II 46016/6/2020-Tech.CPC (Part 2).

Timeline of the n-Butyl Acrylate BIS Certification QCO and Its Suspension

Note: This table reflects only the dates and notifications referenced in the official Gazette notification and its accompanying note. Businesses should verify the current status directly on the Gazette of India portal (egazette.gov.in) or the BIS website (bis.gov.in) before making compliance decisions, since further amendments may follow.

Why Was the n-Butyl Acrylate BIS Certification QCO Suspended?

According to the notification, the Central Government took cognizance of supply chain disruption prevailing at the global level. To ensure continued availability of n-Butyl Acrylate — a key raw material for adhesives, paints, textile binders, and construction chemicals — the government, after consulting the Bureau of Indian Standards, decided it was necessary and expedient to keep the Order's operation temporarily suspended rather than let it lapse or force enforcement mid-disruption.

This approach is consistent with how BIS Quality Control Orders for other petrochemical raw materials (such as ethylene glycol, toluene, and phthalic anhydride) have also seen periodic suspensions or extensions in recent years, when domestic industry has flagged availability concerns.

What This Means for Manufacturers, Importers, and Traders

During the suspension window (up to 31 July 2026)

• Manufacturers of n-Butyl Acrylate are not required to hold a valid BIS license to sell in the domestic market.
• Importers can bring in n-Butyl Acrylate consignments without a mandatory BIS Foreign Manufacturer Certification Scheme (FMCS) license being enforced at customs for this specific product.
• Downstream users — adhesive, paint, and textile-binder manufacturers — can continue sourcing n-Butyl Acrylate without supply interruption linked to BIS compliance.
• Enforcement action for want of the ISI mark on n-Butyl Acrylate is paused for the duration of the suspension.

After 31 July 2026

The suspension is explicitly time-bound. Once the 31st July 2026 deadline is reached, one of the following is likely: the government issues a fresh notification extending the suspension again (as has happened at least once already, on 10th April 2026); the suspension lapses and mandatory BIS certification resumes; or the underlying Order itself is reviewed. Businesses that deal in n-Butyl Acrylate should not treat this suspension as permanent and should keep a compliance calendar tracking the Gazette of India for further notifications.

BIS Certification for n-Butyl Acrylate BIS Certification: How It Works When the QCO Is in Force

When the n-Butyl Acrylate (Quality Control) Order is actively enforced (that is, outside a suspension window), n-Butyl Acrylate must conform to Indian Standard IS 14709:1999 and carry the BIS Standard Mark (ISI Mark) under a licence granted by the Bureau of Indian Standards. This falls under Scheme-I of Schedule-II of the BIS (Conformity Assessment) Regulations, 2018, the same licensing scheme used for other mandatory ISI-marked products. The general process, applicable once the Order is enforceable, typically follows these broad steps:

Indicative only: Exact documentation, fee structure, and timelines vary by BIS branch office and case specifics, and are subject to change by BIS from time to time. Applicants should always verify current requirements, fees, and forms on the official BIS website (bis.gov.in) or the BIS CARE / Manak Online portal before applying.

Typical documents kept ready for a Scheme-I (ISI Mark) application

• Factory registration / incorporation documents and manufacturing license, where applicable.
• Product test reports as per IS 14709:1999 from an accredited or in-house laboratory.
• Details of manufacturing process flow and in-house quality control set-up.
• List of plant, machinery, and testing equipment installed at the unit.
• Authorized signatory and applicant identity/address proof.
• Application fee payment proof, as prescribed by BIS at the time of filing.

Validity and renewal

BIS Scheme-I product licenses are typically granted for a defined validity period and renewed on application before expiry, subject to continued surveillance compliance. Since the n-Butyl Acrylate QCO is currently under suspension, new license issuance and renewal timelines for this specific product should be confirmed directly with BIS once enforcement resumes, as procedures and validity periods are periodically revised through amendments to the BIS Conformity Assessment Regulations.

Compliance Checklist for Businesses Dealing in n-Butyl Acrylate

• Track the Gazette of India (egazette.gov.in) for any further amendment before 31st July 2026.
• Keep IS 14709:1999 test documentation ready in advance, even during the suspension, to avoid a last-minute rush if enforcement resumes.
• Confirm current import requirements with customs/CHA before shipment, since suspension status can change the compliance position quickly.
• Maintain internal records of the applicable S.O. notification number and dates for audit and due-diligence purposes.
• Consult a BIS registration specialist to prepare a Scheme-I application in advance if the QCO is expected to resume.

Conclusion

The extension of the n-Butyl Acrylate QCO suspension to 31st July 2026 gives manufacturers, importers, and downstream industries a short additional compliance window, but it is not a withdrawal of the underlying Quality Control Order. Businesses dealing in n-Butyl Acrylate should treat this as a moving deadline, keep IS 14709:1999-linked documentation ready, and track official Gazette notifications closely so they are not caught off guard if mandatory BIS certification resumes after 31st July 2026 or if the suspension is extended again.
