- BIS on polypropylene ensures quality, safety, and consistency in Indian manufacturing.
- IS 10951:2020 governs BIS certification for polypropylene used in moulding and extrusion.
- Under QCO 2025, testing requirements and compliance processes have tightened for PP materials.
- BIS licence for polypropylene is critical for producers to maintain market credibility and legal conformity.
- Brands like Reliance, Finolex, and Supreme Industries are leading examples of BIS-certified PP adoption.
Introduction
Suresh, a manufacturer of automotive injection-moulded components from Pune, called us in a panic last month. His entire shipment of polypropylene-based plastic parts was stuck at the port because he lacked a valid BIS certificate. His customer, a large automotive OEM, refused to accept the shipment without proof of BIS compliance. The panic was real — after investing over ₹40 lakh in raw material and production, he faced the prospect of total rejection, simply because he missed the latest Quality Control Order (QCO) update.
This is not an isolated case. Across India, polypropylene processors — from pipe manufacturers in Rajkot to packaging film makers in Bhiwadi — are confronting the same wake-up call: no BIS certification means no market access. The 2025 QCO update has further raised the bar, tightening tests under IS 10951:2020. Today, if you want to trade in polypropylene (PP) for moulding and extrusion, a BIS licence is no longer a nice-to-have — it is mandatory, non-negotiable, and a serious brand differentiator.
In this comprehensive guide, let’s break down everything you need to know about BIS on polypropylene in plain business terms, with real-world brand references and a clear-eyed view of the compliance journey.
What is BIS on Polypropylene?
BIS (Bureau of Indian Standards) is the national standards body of India, responsible for setting product benchmarks. When it comes to polypropylene, BIS lays down the essential requirements under IS 10951:2020 for PP materials for moulding and extrusion.
In simple words, if you are making or selling polypropylene granules, resins, or products in India, you must prove they meet the chemical, physical, and mechanical criteria under this standard. This is enforced through a BIS licence scheme.
“BIS is not just a paperwork exercise — it’s a quality shield,” says Mr. Ravi Kulkarni, a polymer technologist from Ahmedabad. “Customers trust a BIS mark the way they trust an ISI mark on electrical wires — it means someone has checked and approved it.”
BIS Certification for Polypropylene: Why It Matters
- Market Trust: Indian brands like Finolex and Supreme openly advertise BIS-certified PP products. It signals durability and performance.
- Regulatory Compliance: Under the latest QCO 2025, selling unlicensed PP is punishable by law, including product seizure.
- Export Acceptance: Even many export clients now demand BIS marking, seeing India’s regulatory scheme as robust.
- Zero Delays: Customs and port clearances go smoothly if you have a valid BIS licence in place.
I remember a client in Vadodara, making PP granules for woven sacks, who saw a 40% boost in order volume after getting BIS approval. Customers simply trusted them more.
Standards in Play: IS 10951:2020
The heart of BIS certification for polypropylene is the Indian Standard IS 10951:2020, officially titled:
“Polypropylene Materials for Moulding and Extrusion – Specification.”
Key aspects:
Melt Flow Index range
Tensile strength minimum
Ash content
Heat deflection temperature
Environmental stress crack resistance
These are tested by a BIS-recognised laboratory. Each grade — whether homopolymer, random copolymer, or impact copolymer — must meet these strict thresholds.
“IS 10951:2020 is the single most important benchmark for BIS polypropylene certification. Miss it, and you miss the entire market.”
QCO 2025 Update: What Changed?
In 2025, the Ministry of Chemicals and Fertilizers updated the Quality Control Order for polypropylene, keeping pace with global norms.
Key highlights include:
| Aspect | Pre-2024 | QCO 2025 |
| Testing Labs | Any NABL-accredited | Only BIS-recognised labs allowed |
| Sample Frequency | Once per quarter | Once per batch |
| Audits | Spot-checks | Mandatory factory surveillance every 6 months |
| Penalties | ₹1 lakh | ₹5 lakh + product seizure |
This means you cannot depend on old stock certificates. Every batch of PP resin must now clear fresh testing under BIS recognition.
“Under QCO 2025, compliance is no longer a tick-mark. It’s an ongoing habit,” as a Delhi-based auditor told me.

Step by step Process of BIS Licence for Polypropylene
Here is a practical step-by-step breakdown:
- Identify your PP grade: Homopolymer, impact copolymer, or random copolymer.
- Apply via BIS portal: Online application under product certification scheme.
- Submit samples: To a BIS-approved lab.
- Factory inspection: BIS officers verify your process, quality controls, and lab equipment.
- Grant of licence: Once tests and inspections clear, you receive the BIS licence.
Typical timeline: 60–90 days if paperwork is in order. But if documentation or testing fails, delays are inevitable.
How Top Indian Brands Leverage BIS Certification to Build Market Trust
Reliance Industries offers grades with BIS-backed certification, especially for injection-moulded automotive parts.
Finolex Industries uses certified PP to produce fittings and piping.
Supreme Industries promotes its BIS-certified packaging solutions in PP.
Haldia Petrochemicals markets PP homopolymer and copolymer with BIS-compliant MFI and stress-crack resistance.
This is not just about a stamp — these brands have used the BIS mark to capture market trust.
Common Mistakes in BIS Polypropylene Certification
In my consulting practice, I have seen these blunders too many times:
- Ignoring pre-shipment testing (biggest delay trigger)
- Failing to update lab accreditations per QCO 2025
- Skipping proper sample retention for repeat verification
- Assuming BIS approval is lifetime (it needs periodic renewal)
- Hiring brokers without checking their BIS experience
Tests for BIS on Polypropylene (Post-QCO 2025)
The updated QCO 2025 now demands:
- Melt flow rate consistency check
- Ash content below 0.3%
- Stress-crack resistance after 1000 hours
- Density uniformity
- Colour dispersion
- Odour evaluation (important for food-grade PP)
These tests are quite strict — so be ready with a reliable lab partner
Cost Involved in BIS on Polypropylene
- Includes government application processing charges
- Involves third-party laboratory testing costs for samples
- Covers factory audit expenses, including auditor travel and stay
- Requires periodic renewals, generally every two years
- Final cost varies by PP grade, unit size, and number of product variants

BIS Certification Under IS 10951:2020 Helped This Supplier Win Back European Clients
A South Indian automotive plastics supplier had chronic rejections from their European customers due to non-standard PP grades. We helped them secure a BIS licence for polypropylene under IS 10951:2020, with strict melt flow index validation. Within six months, their customer acceptance rate jumped to 98%. In fact, the European buyer specifically cited BIS as a mark of consistent quality
Conclusion
In today’s competitive plastics market, securing your BIS on polypropylene licence is not just about following the rules — it is about protecting your market share, your brand name, and your reputation for quality. As seen with the QCO 2025 update, authorities are tightening controls to filter out substandard PP, while customers increasingly refuse products without a BIS stamp.
I have seen manufacturers lose crores in potential orders simply because they delayed BIS compliance, assuming it was an optional mark. That is a dangerous mindset. BIS certification under IS 10951:2020 has effectively become the industry passport to trade. Think of it like a visa: without it, you cannot travel in the marketplace.
Furthermore, with the new BIS lab test mandates and biannual audits, even your suppliers must be chosen carefully to avoid future non-compliance. Big brands like Supreme and Reliance have shown that getting BIS-certified can boost trust, drive new B2B partnerships, and cut down port clearances. For your brand, following their lead is an investment — not a burden.
If you are still on the fence, I would strongly urge you to start the BIS application as soon as possible, rather than waiting for the next enforcement wave. In my professional opinion, polypropylene manufacturers who proactively adapt to the BIS requirements will stand out in 2025 and beyond.
Whether you are in woven-sack resin, automotive parts, or packaging films, do not leave compliance to chance. Take expert advice, get your BIS testing lined up, and secure that licence for uninterrupted business growth.
