On July 17, 2026, Bharatiya Reserve Bank Note Mudran Private Limited or BRBNMPL, invited global companies to express interest in supplying specialised polymer sheets for Indian banknotes. BRBNMPL operates as a wholly owned subsidiary of the Reserve Bank of India and prints a large share of India’s currency.
The development shows that India has moved beyond a general discussion and has started identifying suitable materials and suppliers. It still does not confirm when polymer notes will enter circulation, which denominations India will select or whether the RBI will approve a nationwide rollout. Has BRBNMPL Announced?
BRBNMPL issued a Global Expression of Interest for companies capable of manufacturing and supplying opacified polymer substrate sheets with security features suitable for Indian banknotes.
A polymer substrate acts as the base material on which a currency-printing press prints a banknote. Ordinary Indian notes currently use a specialised cotton-based material rather than conventional wood-pulp paper.
The new tender seeks polymer material based on BOPP, or biaxially oriented polypropylene. Manufacturers widely use this strong and flexible form of plastic for applications that require durability and resistance to moisture.
According to details reported from the tender, BRBNMPL has indicated a requirement of 68,000 reams of polymer substrate. It has divided this quantity equally between two denominations, with 34,000 reams for each denomination. Each ream would contain 500 sheets.
The official tender opened on July 17, 2026, and BRBNMPL has set August 18, 2026, as the closing date. This Mean Plastic Notes Are Coming Soon?
The tender makes polymer notes more likely than before, but it does not confirm an immediate public launch.
An Expression of Interest usually helps an organisation identify capable suppliers, study available technologies and assess whether manufacturers can meet technical and security requirements. It comes before a final commercial order in many procurement processes.
BRBNMPL has not announced a circulation date. The RBI has not released a new polymer banknote design, and the government has not notified any change to the legal status of existing currency notes.
India is exploring new technology across several sectors, from polymer banknotes to understanding how India’s first hydrogen train works without diesel.
The process could still involve several stages:
- BRBNMPL evaluates potential suppliers.
- Selected companies provide samples for testing.
- Currency printers examine the material’s strength, print quality and security.
- Authorities conduct controlled field trials.
- The RBI and central government review the results.
- Officials decide whether to approve limited or wider circulation.
Some stages may take considerable time. Testing must show that the notes work reliably in India’s climate, banks, cash-counting machines, ATMs, retail systems and daily cash transactions.
Therefore, people should treat the tender as a preparatory step, not as an announcement that plastic currency will enter their wallets immediately. xisting Indian Currency Notes Still Valid?
Yes. Existing Indian banknotes remain valid unless the RBI or the Government of India issues a clear official notification stating otherwise.
A viral claim circulated in June 2026 saying that the RBI would withdraw paper notes and replace them with plastic currency from June 30. The government’s PIB Fact Check unit rejected that claim. The clarification said the RBI had announced no such withdrawal or replacement deadline.
The July tender does not automatically change the validity of any banknote. A procurement notice for testing or sourcing new material cannot demonetise currency already in circulation.
Even if India eventually introduces polymer notes, authorities could allow polymer and cotton-based notes to circulate together. Countries commonly introduce redesigned notes gradually while removing older notes only when they become damaged or unsuitable for circulation.
People should not rush to banks, refuse current notes or pay anyone to exchange their currency. Only official RBI notices can confirm a change in the status of Indian money. Exactly Is a Polymer Banknote?
A polymer banknote uses a thin plastic film as its main base instead of cotton-based currency paper.
Manufacturers normally apply opaque coatings to most of the transparent plastic film. These coatings create a printable surface while allowing selected areas to remain clear. This process explains the term “opacified polymer substrate.”
The result can look and feel different from a traditional Indian banknote. A polymer note may feel smoother, resist water more effectively and include transparent sections that form part of its security design.
Countries including Australia, Canada, the United Kingdom and New Zealand already use polymer banknotes in some or all denominations.
Polymer currency does not mean a simple sheet of household plastic. Currency suppliers manufacture it under highly controlled conditions and integrate specialised layers, inks and security elements that ordinary printing equipment cannot reproduce easily.
What Security Features Could India’s Polymer Notes Carry?
The tender seeks material that can support several visible and machine-readable security features.
Reported requirements include:
- A clear window containing a portrait
- A metallic denomination numeral
- A magnetic pseudo-security thread
- A shadow image
- An iridescent pattern that changes appearance under light
A transparent window represents one of the most recognisable features of polymer money. Manufacturers create it as part of the note’s base rather than printing it as an ordinary image. Counterfeiters therefore face greater difficulty reproducing the window’s material, design and additional elements accurately.
The RBI could also combine polymer features with microtext, colour-changing effects, raised printing, machine-readable markers and other protections. However, authorities have not revealed a final Indian polymer-note design.
India must keep many specifications confidential because public disclosure could weaken currency security. s India Considering Polymer Currency?
Polymer notes could solve several practical problems connected with the heavy use of cash.
Longer life in circulation
People frequently fold, crumple and handle low-denomination notes. Shopkeepers, street vendors, buses, markets and small businesses may pass the same note between many people in a single day.
Moisture, sweat, dirt and repeated folding gradually damage cotton-based currency. Polymer handles several of these conditions more effectively and can remain usable longer.
A longer lifespan could reduce how often currency printers need to replace damaged notes. Although polymer material may cost more initially, a longer circulation life could reduce long-term replacement expenses.
Better resistance to water and dirt
Indian currency regularly faces humid weather, monsoon rain and rough handling. Polymer does not absorb water as quickly as a cotton-based note.
Its relatively non-porous surface can also prevent some dirt and moisture from entering the material. People may find it easier to wipe a polymer note without immediately damaging it.
However, polymer notes can still suffer scratches, creases, heat damage or cuts. They do not last forever.
More complex anti-counterfeit features
Polymer gives currency designers additional ways to build security into the note’s physical structure. Transparent windows, metallic elements and layered optical effects create obstacles for counterfeiters.
No banknote can remain completely immune to forgery. Authorities must continue updating designs and detection systems as counterfeiters learn new techniques.
Which Indian Denominations Could Become Polymer Notes?
The procurement details refer to two denominations but do not officially identify them in the public tender notice.
Some reports citing people familiar with the process have suggested that India may initially consider ₹10 and ₹20 notes. Lower denominations would provide a practical testing ground because they change hands frequently and experience heavy wear.
However, people should not treat ₹10 and ₹20 as confirmed choices until BRBNMPL, the RBI or the government names the denominations officially.
Authorities may use the initial procurement for tests rather than public circulation. They could also change the chosen denominations after examining cost, printing performance and field-trial results.
The tender does not announce a new ₹500 note, and it does not say that India will immediately convert every denomination into polymer.
Will Polymer Notes Cause Another Demonetisation?
The tender provides no evidence of another demonetisation.
Demonetisation removes the legal-tender status of specific currency notes through an official government decision. Purchasing polymer sheets or testing new banknote materials does not produce that legal effect.
India could introduce polymer notes without suddenly invalidating existing notes. The RBI could issue new notes gradually while banks remove old, damaged notes through the normal currency-management process.
People should remain cautious about social media posts that attach urgent exchange dates to the polymer-note discussion. Rumours often use words such as “RBI order,” “last date” or “mandatory exchange” without linking to a genuine RBI notification.
A real currency change would appear through official RBI and government communication, followed by detailed instructions for banks and the public.
What Challenges Must India Solve Before a Rollout?
Polymer currency also creates practical and financial challenges.
Currency printers may need new settings, inks or equipment to handle the material. Banks and cash-processing companies may need to recalibrate counting, sorting and authentication machines.
ATMs and cash-recycling machines must recognise the dimensions, texture and security markers of every new note. Retailers, transport operators and other cash-heavy businesses must also learn how to identify genuine notes.
India would need a secure supply of specialised polymer material. Authorities must assess supplier reliability, production capacity, national-security risks and dependence on foreign technology.
Officials would also need systems for collecting, destroying or recycling damaged polymer notes. Cotton-based notes and plastic-based notes require different end-of-life processes.
These challenges help explain why the RBI has continued examining the advantages and disadvantages instead of announcing an immediate transition.
What Happens Next?
Interested suppliers can submit responses to BRBNMPL before the August 18 deadline. The currency printer can then evaluate their experience, technology, manufacturing capacity, financial strength and ability to comply with India’s security conditions.
Reports indicate that applicants must provide sample sheets for laboratory examination. Authorities can test those samples for print quality, durability, machine readability and compatibility with currency-printing presses.
A successful evaluation could lead to a more specific procurement tender, pilot printing or controlled field trials. A wider launch would require further approval and public communication.
Until those steps occur, India’s polymer currency project remains under evaluation.
What Indian Currency Users Should Remember
BRBNMPL’s global tender marks genuine progress towards testing polymer banknotes in India. It shows that the country has started exploring suppliers and technical materials in a structured way.
However, the tender does not confirm a launch date, a final design or the immediate replacement of paper notes. Existing Indian currency remains valid, and people do not need to exchange their cash because of this announcement.
India may eventually introduce durable polymer notes with transparent windows and advanced security features. The next important signals will come from supplier selection, material testing, pilot announcements and an official RBI decision—not from viral messages on social media.
Frequently Asked Questions
Are existing Indian banknotes still valid?
Yes. Existing banknotes remain valid unless the RBI or the Government of India issues an official notification changing their legal status.
Do people need to exchange their paper notes for plastic notes?
No. There is no official exchange requirement. People should ignore messages claiming that paper notes must be deposited or exchanged by an unverified deadline.
What is a polymer banknote?
A polymer banknote uses a thin and durable plastic-based material instead of the cotton substrate commonly used for Indian currency. It can include transparent windows and advanced security features.
Are polymer notes completely waterproof?
Polymer notes resist water better than cotton-based currency, but they are not indestructible. Heat, deep cuts, heavy creasing and prolonged damage can still make them unusable.
