BIS Standards for Recycled Materials: What’s Notified, What’s Coming, What It Means for Buyers

Updated: September 18, 2026 · 16 min read

A Central Public Works Department tender floated in Delhi-NCR in early 2026 quietly included a clause that rattled several mid-sized construction firms: recycled aggregate supplied must conform to Bureau of Indian Standards (BIS) specification IS 383:2016, and third-party test certificates must accompany each consignment. For firms buying C&D-derived aggregates from unregistered processors at ₹18–₹22 per cubic foot, the clause created an immediate disqualification risk. This is what happens when BIS recycled materials standards move from a technical appendix into a contract clause — and it is happening faster than most procurement teams have registered.

This guide is written for procurement officers, R&D leads, civil engineers and sustainability heads who need to understand which standards are already in force, which are coming, and what the practical cost-quality calculus looks like when specifying recycled inputs in 2026.

Why BIS Recycled Materials Standards Are Now a Tender-Stage Issue

For most of the last decade, BIS recycled materials standards occupied a corner of the specification document that buyers could safely ignore. Recycled content was purchased on price; quality was managed through in-house testing at best, experience at worst. That arrangement is under pressure from two directions simultaneously.

First, the Government of India’s National Infrastructure Pipeline and PM GatiShakti programme have pushed the volume of publicly funded construction to a scale where raw material sourcing policies actually matter to aggregate supply chains. The NITI Aayog circular economy report of 2021 estimated that India generates approximately 150 million tonnes of construction and demolition waste annually, of which less than 1% is formally processed. Closing that gap requires not just processing capacity but a standards framework that gives specifiers the confidence to replace virgin aggregate.

Second, BIS itself has become more active. The Bureau has been aligning its recycled-material specifications with its Quality Control Orders regime, which means non-conforming material can, in principle, attract legal consequences under the Bureau of Indian Standards Act, 2016 — not merely a failed tender bid. Procurement leads who treat BIS conformity as optional are, in 2026, reading an outdated risk map.

Notified IS Codes: Recycled Aggregates, Secondary Steel and Recycled Plastics

Recycled Aggregate: IS 383:2016

IS 383:2016 — “Coarse and Fine Aggregate for Concrete — Specification” — is the primary IS code governing recycled aggregate for structural use. The 2016 revision, which superseded the 1970 edition, introduced a dedicated category for recycled coarse aggregate (RCA). The specification permits substitution of up to 30% RCA by weight in structural concrete (M35 grade and below), subject to the aggregate meeting limits on water absorption (maximum 6%), sulphate content and Los Angeles abrasion value. This is not a blanket permission — the clause applies where the design engineer has specifically approved the substitution, and the RCA must come from crushed concrete rubble, not mixed C&D waste streams.

The practical implication is stark: if your aggregate supplier cannot produce a test certificate against IS 383:2016, Clause 4.6 (which governs recycled aggregate sub-classification), you are not supplying a conforming material — regardless of what the material physically is. Several infrastructure contractors in Pune and Bengaluru discovered this when internal audits in FY 2025-26 flagged their aggregate sourcing as specification non-compliant.

Secondary Steel: IS 2830 and the BIS Conformity Mark

Secondary steel in India is governed primarily by IS 2830 — “Medium Tensile Steel Blooms, Slabs and Bars for Re-Rolling” — along with IS 1786:2008, which covers high-strength deformed bars (TMT bars) produced from either primary or secondary routes. The Ministry of Steel has extended the Quality Control Order (QCO) for steel bars and structural steel to cover secondary-route producers, meaning that TMT bars sold in India must carry the BIS Standard Mark irrespective of whether they are produced from iron ore or scrap. As of FY 2026-27, re-rolling mills using MS scrap — where rates ranged from ₹32 to ₹38/kg across Mumbai and Thane yards in Q1 2026 — must obtain and maintain BIS certification under IS 1786:2008 to sell legally into the construction market. Non-certified secondary steel bars cannot be lawfully supplied to any CPWD, MoRTH, or NHAI project.

Recycled Plastics: IS 14534 and Evolving Standards

IS 14534:1998 — “Guidelines for Recycling of Plastics” — remains the foundational BIS document for recycled plastic material, though it is broadly acknowledged as outdated relative to current processing technology. For specific product categories, more recent standards apply: IS 16826:2018 covers specifications for recycled HDPE pipes, and IS 15778:2007 governs chlorinated PVC (CPVC) applications that may use recycled resin blends subject to property retention. The gap in the standards architecture — the absence of a raw-granule quality specification for recycled PET and HDPE — is what the 2025-26 BIS drafting exercise is designed to address (discussed in the next section).

Material Category	Relevant IS Code	Status (2026)	Key Limit / Parameter	Applicable Buyer Segment
Recycled Coarse Aggregate	IS 383:2016 (Cl. 4.6)	Notified and in force	Max 30% substitution; water absorption ≤6%	Construction, civil engineering
Secondary Steel (TMT Bars)	IS 1786:2008	QCO-mandated BIS Mark	Yield strength ≥500 MPa (Fe 500D grade)	Construction, fabrication
Recycled HDPE Pipe	IS 16826:2018	Notified; BIS Mark applicable	MRS rating; ring stiffness class	Water utilities, irrigation
Recycled Plastic (General)	IS 14534:1998	In force; revision under review	Guidelines only; no mandatory mark yet	Manufacturing, packaging R&D
Recycled PET / HDPE Granules	Draft standard (2025-26)	Draft circulated; gazette notification expected Q3 FY 2026-27	Intrinsic viscosity, MFI, contamination limits	FMCG packaging, auto components

Draft Standards in the Pipeline: What BIS Is Working On Right Now

The most consequential standards development in FY 2025-26 relates to recycled polymer granules. BIS’s Technical Committee PCD 12 (Plastics) circulated draft specifications for recycled PET (rPET) granules and recycled HDPE granules in the second half of 2025 — a move directly catalysed by the Plastic Waste Management Rules, 2016 (as amended in 2024), which tightened Extended Producer Responsibility targets and created commercial demand for certified recycled content. The draft specifications set out minimum intrinsic viscosity thresholds for rPET (≥0.72 dl/g for food-contact grade), melt flow index ranges for rHDPE, and maximum permissible contamination levels. Industry feedback, including submissions from the Plastics Export Promotion Council, pushed back on the food-contact grade viscosity floor; BIS is expected to publish a revised draft before gazette notification.

On the aggregate side, BIS Technical Committee CED 2 (Cement and Concrete) has been deliberating revision of IS 383 to expand recycled aggregate use to M40-grade concrete, with reference to research published by the National Council for Cement and Building Materials (NCCBM). No formal draft has yet been released for public comment as of September 2026, but the revision is listed in BIS’s published work programme for FY 2026-27. Civil engineers specifying high-performance concrete should track this revision closely — it could open a substantially larger procurement window for recycled aggregate in bridge and flyover construction.

There is also a pending alignment exercise for secondary aluminium alloy standards. India’s secondary aluminium industry — processing UBC and automotive scrap into alloy ingots — currently operates against IS 617:1994 (Aluminium Alloy Ingots), which predates modern scrap-based metallurgical practice. BIS PGD 28 (Light Metals) is expected to take up a revision in FY 2027-28, but procurement teams in the automotive tier-1 space should note that current practice already requires conformance certificates even under the older standard.

The Regulatory Stack: Three Rules That Make BIS Conformity Legally Consequential

BIS standards do not exist in isolation. Three pieces of subordinate legislation tie them to legal obligation in a way that transforms conformity from a quality preference into a compliance requirement.

1. The Construction and Demolition Waste Management Rules, 2016 (notified by MoEFCC under the Environment (Protection) Act, 1986) require urban local bodies (ULBs) in cities with a population exceeding one million to establish C&D waste processing facilities and to mandate the use of recycled C&D products in their own construction works. Rule 6(g) specifically requires that recycled products meet relevant IS codes — which, for aggregate, means IS 383:2016. A ULB that procures non-conforming recycled aggregate is in breach of its own rules obligations, not merely making a poor quality choice.

2. The Plastic Waste Management Rules, 2016 (as amended in 2024) impose EPR obligations on producers, importers and brand owners, requiring them to use recycled plastic content in their packaging at rising percentages — reaching 60% recycled content in rigid plastic packaging by FY 2026-27 for large producers. As BIS granule standards are notified, they will almost certainly be referenced in EPR compliance documentation, making certified recycled polymer a procurement prerequisite rather than a CSR gesture.

3. The Bureau of Indian Standards Act, 2016 gives BIS the authority to issue Quality Control Orders (QCOs) in coordination with sectoral ministries. Once a QCO is issued for a material category, selling non-conforming material becomes a criminal offence under Section 29 of the Act — with penalties up to ₹2 lakh for a first offence and up to ₹5 lakh for repeat violations, alongside potential product seizure. The Ministry of Steel has already used QCOs extensively for primary and secondary steel. The question procurement teams should be asking is: which other recycled material categories will be covered next?

For those managing construction and demolition waste streams, the intersection of these three frameworks means that what was previously a disposal problem now has a procurement dimension — and one that is increasingly regulated on both ends of the supply chain.

BIS Conformity vs. Cost: The Trade-Off Procurement Teams Are Getting Wrong

The standard objection to BIS-conformant recycled inputs is price. A verified, IS 383:2016-compliant recycled aggregate — one that comes with a third-party test certificate from a NABL-accredited laboratory — typically costs 8–14% more per tonne than uncertified C&D-derived aggregate sourced from informal processors. For a large civil project consuming 50,000 tonnes of aggregate, that differential can reach ₹40–₹70 lakh over the project life. Procurement managers under budget pressure find this uncomfortable.

The error in that calculation is that it ignores the liability leg. A project that uses non-conforming aggregate and subsequently fails a quality audit — or worse, faces a structural defect claim — faces costs of a different order. CPWD’s own quality audit regime has been tightened in FY 2025-26, with third-party technical auditors empowered to flag specification deviations directly to the Chief Vigilance Officer. Contractors found using non-conforming materials risk being placed on debarment lists, which in the government contracting market is a commercial death sentence.

The secondary steel picture is cleaner. MS scrap-based TMT bars from BIS-certified re-rolling mills are no longer significantly more expensive than uncertified material — because the QCO has effectively eliminated the uncertified segment from the formal market. What remains is a quality differentiation question within the certified segment: Fe 500D versus Fe 500, or tested heat versus untested heat. For structural applications in seismic zones (which covers large swaths of Maharashtra, Gujarat and Uttarakhand), specifying Fe 500D under IS 1786:2008 is both a code requirement and an insurance underwriting consideration.

For recycled plastics, the cost-quality trade-off is most acute. rPET granules meeting food-contact grade specifications command a 20–35% premium over general-purpose rPET. But with FMCG majors under BRSR Core reporting obligations (under SEBI‘s circular dated 12 July 2023) now required to disclose recycled content percentages, the procurement function is acquiring a disclosure accountability it did not previously carry.

The 7-Point Procurement Checklist for BIS-Compliant Recycled Inputs

If your organisation is buying or specifying recycled aggregates, secondary steel, or recycled plastics for the first time under BIS frameworks, the following actions should be completed this quarter:

1. Map your recycled input categories to their IS codes. Confirm whether each material you buy — aggregate, steel bar, plastic granule, aluminium ingot — has a notified IS code and whether that code is referenced in your tender or purchase order specifications.
2. Audit your current supplier’s certification status. Ask for their BIS licence number (for Standard Mark holders) or their NABL-accredited lab test report against the relevant IS code clause. A certificate from a non-NABL lab is insufficient for CPWD and MoRTH tenders.
3. Insert BIS conformity clauses into your standard purchase orders. Your legal or contracts team should draft a clause requiring the supplier to warrant conformity with the relevant IS code and to indemnify you against claims arising from non-conformance. This is contract hygiene, not overkill.
4. Check whether a Quality Control Order (QCO) exists for your material category. If it does, purchasing non-BIS-marked material from any supplier — Indian or imported — is a criminal offence under the BIS Act, 2016. Do not wait for enforcement to discover this.
5. Track BIS’s work programme for draft standards relevant to your inputs. BIS publishes its technical committee work programmes. If you consume recycled PET or HDPE granules, the pending standard should already be on your regulatory watch list.
6. Align recycled input documentation with your BRSR or ESG reporting cycle. SEBI’s BRSR Core framework requires large listed companies to disclose the percentage of recycled inputs used in production. Your procurement records need to be documentary-grade, not anecdotal.
7. Engage your waste dealer or recycling partner on documentation requirements upfront. A recycler who cannot produce a chain-of-custody record and a test certificate against the applicable IS code is not a viable supplier for regulated procurement channels. Qualify suppliers before awarding contracts, not after.

Frequently Asked Questions

Is IS 383:2016 mandatory for all construction projects using recycled aggregate?

IS 383:2016 is a voluntary standard unless it is invoked by a specific contract, specification, or statute. However, the Construction and Demolition Waste Management Rules, 2016 (Rule 6) require urban local bodies to mandate IS-code-conformant recycled products in their own projects. All CPWD and MoRTH contracts referencing the Ministry’s standard specifications incorporate IS 383:2016 by reference — making it effectively mandatory for government-funded construction. Private developers operating under RERA-registered projects are not yet uniformly required to use IS-conformant recycled aggregate, but this is an evolving position.

What penalty does a re-rolling mill face for selling non-BIS-marked TMT bars?

Under the Bureau of Indian Standards Act, 2016, selling goods covered by a Quality Control Order without the Standard Mark is a cognisable offence. Section 29 of the Act provides for imprisonment of up to two years and/or a fine of up to ₹2 lakh for a first offence, rising to ₹5 lakh for subsequent violations. Consignments may also be seized. The Ministry of Steel’s QCO for steel bars has been in force since 2018, and enforcement has tightened perceptibly since FY 2024-25, with BIS field offices conducting surprise inspections at re-rolling mills in Mandi Gobindgarh, Raipur and Thane clusters.

When is BIS expected to finalise the recycled PET and HDPE granule standard?

BIS Technical Committee PCD 12 circulated the draft specifications for recycled PET and HDPE granules for public comment in late 2025. Based on the typical BIS drafting timeline — two comment rounds and a finalization meeting — gazette notification is expected in Q3 FY 2026-27, i.e., between October and December 2026. Buyers who process or trade recycled polymer granules should register as stakeholders on the BIS portal to receive draft amendments directly and to participate in comment rounds that could affect the final specification limits.

Does recycled content sourced from informal processors qualify under BIS standards?

No. BIS conformity requires material to meet the physicochemical and mechanical parameters specified in the relevant IS code, verified by testing at a NABL-accredited laboratory. Material sourced from informal processors — who typically lack quality management systems and NABL testing access — cannot produce the required conformity certificate. Beyond quality, there is a GST compliance dimension: informal processors often cannot supply GST-compliant invoices with the correct HSN code for recycled materials, creating an input tax credit risk for buyers. Formal, registered recyclers are the only viable source for regulated procurement channels.

How does BIS recycled material conformity interact with BRSR Core reporting?

SEBI’s BRSR Core framework (introduced under SEBI’s circular dated 12 July 2023) requires the top 150 listed entities by market capitalisation to disclose, with reasonable assurance, the percentage of recycled inputs used in their operations. BIS-conformant recycled inputs — backed by test certificates and chain-of-custody documentation — provide the documentary foundation for these disclosures. Undocumented recycled inputs, even if physically genuine, cannot be reported with assurance. As BRSR Core disclosure requirements extend progressively to the top 250, then top 500 listed entities in subsequent financial years, the documentation discipline required of procurement teams will only increase.
