MAF stands for Manufacturer Authorisation Form. It is a letter issued by the manufacturer of the goods being tendered, addressed to the tender inviting authority, which names one specific bidder and authorises that bidder to quote, supply and support the manufacturer’s products against that specific tender.
That is the full answer. Everything below is the detail a bidder actually needs: what buyers are checking when they ask for it, what the letter usually has to contain, how it differs from a dealer certificate or an OEM certificate, how to get one without holding up your bid, and the single mistake that gets more MAFs rejected at evaluation than any other.
Some tenders call it a Manufacturer’s Authorisation Form, some a Manufacturer Authorization Certificate, some simply an authorisation letter from the OEM. In Indian government and institutional procurement the abbreviation MAF is the one you will see most often, and it means the same thing in all of them.
Why the buyer asks for a MAF at all
I have been manufacturing and exporting laboratory, engineering and incineration equipment since 1993, and I have issued a great many of these letters. The purpose is easy to state from the buyer’s side of the table.
A tender is open. Anyone can download it and quote. Nothing in the bid form stops a trading firm with no relationship to any manufacturer from quoting a well known brand at a keen price, winning, and only then trying to find someone who will sell it to them. When that fails, the buyer has a cancelled award, a re-tender, and a lost financial year.
The MAF closes that gap. By insisting on a letter from the maker, naming this bidder and this tender, the buyer is testing four things at once:
| What the buyer is testing | What the MAF proves |
|---|---|
| Can this bidder actually get the goods | The manufacturer has confirmed in writing that it will supply this bidder for this tender |
| Are the goods genuine | Supply is routed through the maker, not through grey stock, refurbished units or lookalike equipment |
| Who stands behind the warranty | The manufacturer accepts responsibility for warranty and technical support, so the buyer is not left with a defunct trading firm as its only recourse |
| Is there an after-sales route | Spares and service are backed by the maker rather than promised by an intermediary. Our note on spare parts and after-sales support covers what a serious commitment looks like |
There is a second, quieter reason. A MAF requirement thins the bid list. Every buyer who has been burnt once writes it into the next tender. If you are on the buying side and drafting the document, our tender documents checklist for government colleges sets out where the MAF clause normally sits among the rest of the qualifying papers.
What a MAF typically contains
Read this as what is commonly asked for, not as a fixed legal format. There is no single national template. The tender document itself is the authority. If it carries an annexure with a prescribed MAF wording, use that wording, on the manufacturer’s letterhead, without editing it. Bidders lose marks for improving the buyer’s format.
| Element | Why the evaluator cares |
|---|---|
| Manufacturer’s letterhead, full address, and contact details | Establishes that the letter came from the maker and gives the buyer a way to verify it independently. Many buyers do telephone or email the manufacturer |
| Date of issue | Shows the letter was written for this tender and not lifted from an older file |
| Tender reference number, title, and the buying authority’s name | This is what makes the MAF tender-specific. A letter without the reference number is usually treated as a generic dealer letter, not a MAF |
| Bidder’s legal name and registered address | Must match the name on the bid exactly, including suffixes such as Pvt Ltd or LLP. A trading name that differs from the registered name causes queries |
| Product description and model numbers covered | The most heavily scrutinised line. See the section below on model mismatch |
| Statement of authorisation | The operative sentence: that the manufacturer authorises the named bidder to quote, supply and, where relevant, install the listed products against this tender |
| Warranty and after-sales support commitment | Confirms the maker will honour warranty terms and provide technical support and spares through the authorised bidder. The period and terms are whatever the tender and the supply contract specify |
| Validity of the authorisation | Must cover the bid submission date, and buyers increasingly want it to cover the bid validity period too |
| Name, designation, and signature of the authorised signatory, with company seal | An evaluator will ask whether the person signing can bind the manufacturer. A sales executive’s signature is sometimes challenged |
Some tenders add more: a declaration that the manufacturer has not appointed another bidder for the same tender, a statement that the manufacturer will step in and complete supply if the bidder defaults, or a requirement that the MAF be notarised or submitted on stamp paper. Read the annexure. Do not assume.
MAF, dealer certificate, distributor certificate, OEM certificate
These four appear in the same tender documents and are constantly confused, including by people writing the tenders. The distinction is worth getting right because submitting the wrong one is a common cause of technical rejection.
| Document | What it says | Tender-specific | Typical use |
|---|---|---|---|
| Manufacturer Authorisation Form (MAF) | This manufacturer authorises this named bidder to quote and supply these products for this named tender | Yes. Issued fresh for each tender and normally not reusable | Submitted with the technical bid as a qualifying document |
| Authorised dealer certificate | This firm is an appointed dealer of the manufacturer, usually for a territory and a period | No. It is a standing relationship document with its own validity period | Proves an ongoing channel relationship. Accepted in place of a MAF only where the tender explicitly says so |
| Sole distributor certificate | This firm is the only appointed distributor for a defined territory or product line | No | Common in import supply, and often used to justify a single-source or proprietary purchase. It says exclusivity, which a MAF does not |
| OEM certificate | A broad term. Usually a self-declaration by the manufacturer confirming it actually manufactures the goods, sometimes with works address, registration and quality certification details | Varies | Used where the buyer wants to confirm the quoted party is the maker rather than a rebadger. Sometimes asked of the manufacturer behind a bidder |
The practical rule: a dealer or distributor certificate describes a relationship, a MAF grants permission for a transaction. A buyer who has asked for a MAF and receives a dealer certificate has been handed a different document that answers a different question, and a strict evaluation committee will mark the bid non-responsive.
If you hold a dealership and are unsure which of your papers a given tender wants, ask the buyer during the pre-bid clarification window. That window exists precisely for this. Firms considering taking on a line for the first time will find our page on the distributor and dealership route useful for what a manufacturer expects in return.
How to obtain a MAF without holding up your bid
Approach the manufacturer as soon as you decide to bid, not the evening before submission. A MAF is tender-specific, so there is no stock copy waiting in a drawer. Someone has to draft it, check it, and get it signed by a person with authority to sign.
Send the manufacturer everything needed in one message:
| What to send | Why it saves a round trip |
|---|---|
| The exact tender reference number, title, and issuing authority | These go into the letter verbatim. An abbreviation or a portal ID instead of the reference number causes a re-issue |
| The tender’s prescribed MAF annexure, if there is one | Lets the manufacturer use the buyer’s own wording instead of its house format |
| The exact item list you intend to quote, with the tender’s item numbers | The MAF must cover what you quote. Nothing more, nothing less |
| Your registered legal name and address as it appears in the bid | Name mismatches between the MAF and the bid form are queried at evaluation |
| The bid submission deadline and the bid validity period | So the validity of the authorisation is set to cover both |
| Whether notarisation, a seal, or a digital signature is required | Physical formalities take days that you may not have |
Then check three things before you upload it. First, that the validity date on the letter is beyond the bid deadline, and preferably beyond the bid validity period. Second, that the signatory’s designation is stated and is senior enough to bind the manufacturer. Third, that the tender reference on the letter matches the tender reference on your bid character for character.
The model mismatch that kills most MAFs
In my experience the single most common reason a MAF is rejected at technical evaluation is not a missing seal or a late signature. It is that the models listed on the MAF do not match the models quoted in the bid.
It happens in a predictable way. The bidder asks for a MAF early, gets it, then changes the offer. A model is substituted after a pre-bid clarification. An item is added because the buyer amended the schedule. The price bid is built from a newer configuration. Nobody goes back and refreshes the MAF, and the evaluator, comparing two lists side by side, finds an item quoted that the manufacturer never authorised.
The fix is procedural, not clever. Freeze your item list, then request the MAF against that frozen list. If anything in the offer changes afterwards, including after a corrigendum, request a revised MAF. Manufacturers reissue these routinely and it costs nothing but a day.
The same discipline applies to the specification itself. Where the quoted model does not literally meet a written specification line, no authorisation letter will rescue the bid. Buyers writing those lines will get more comparable bids by following our guide to writing lab equipment specifications, and bidders should read the specification against the datasheet before requesting anything.
Why a manufacturer might decline, and what to do about it
A refusal is rarely personal. The usual reasons:
| Reason | What a bidder can do |
|---|---|
| The manufacturer has already authorised another bidder for the same tender, and the tender permits only one | Ask early. Authorisation for a given tender is often first come. If you are second, consider a different make for that item |
| The manufacturer has an exclusive channel partner for that territory | Route the enquiry through that partner rather than around it. Trying to bypass the channel usually ends the conversation |
| The quoted price undercuts what the manufacturer can supply at | Confirm your landed cost with the manufacturer before you finalise the price bid, not after |
| The manufacturer does not make some of the listed items | Split the MAF request by make. A multi-item tender frequently needs several authorisation letters, one per manufacturer |
| No commercial history and no credit comfort with your firm | Offer advance payment or a letter of credit for the first order, and expect due diligence to run both ways. Our note on evaluating a manufacturer works equally well read in reverse |
| The tender is written around a competitor’s proprietary feature | Raise it in the pre-bid meeting. If the specification cannot be met, walk away rather than quote a non-compliant model behind a MAF |
One more situation catches distributors out. Some tenders demand that the MAF be supported by documents the manufacturer may not hold. Accreditation-linked purchases are the usual source of this, and the requirements differ between NBA, NAAC and AICTE driven procurement. Check what supporting papers the buyer expects alongside the MAF, because asking for all of them in one go is far faster than three sequential requests.
On e-procurement portals the mechanics change but the substance does not. The MAF is uploaded as a scanned document against the technical bid, and the same checks on reference number, model list and validity apply. Our GeM procurement guide covers how authorisation and OEM documentation are handled there. For export orders, the authorisation letter usually travels alongside a separate set of shipping papers, which we cover in the export documentation guide.
A note on incinerator tenders specifically
Incinerator tenders carry an extra layer that catches bidders who treat them like ordinary equipment supply. Installation and operation of incineration plant in India is a regulated activity. Consent to establish and consent to operate are obtained from the State Pollution Control Board, the Central Pollution Control Board issues guidelines, and biomedical waste handling is governed by the Bio-Medical Waste Management Rules.
What that means for a MAF is simple. The authorisation letter proves you may supply the machine. It does not, and cannot, prove that the installation will be permitted. Emission parameters, stack requirements, siting conditions and operating conditions are as specified by the applicable rules and by your State Pollution Control Board, and you must confirm them for the specific site and waste stream before you commit to a configuration. For export destinations, confirm the environmental requirements of the destination country.
We build to suit the parameters specified by the buyer and the consenting authority. We do not certify a machine as compliant with an environmental regulation, because compliance is determined for an installation and a permit, not for a catalogue entry. Our incinerator manufacturing page sets out the range and the questions worth settling before a specification is frozen.
Requesting a MAF from Scientico
We issue Manufacturer Authorisation Forms to bidders quoting our products in a tender. We have manufactured and exported laboratory and engineering teaching equipment and incinerators from our own works in Ambala, Haryana since 1993, and supply to more than sixty countries. We are ISO 9001:2015 certified, and CE conformity documentation is available on applicable models, which you can see on our quality certifications page.
Two points of honesty, because both come up in tender annexures. We are not ISO/IEC 17025 or NABL accredited, and the calibration certificates we supply are factory calibration certificates. If a tender demands NABL traceable calibration, that has to be arranged separately through an accredited laboratory, and it is better to know that at bid stage than at inspection. Our calibration and maintenance guide explains how buyers usually structure this, and where a tender references test standards our note on IS and ASTM standards in testing may help you read the specification.
Catalogues and datasheets to build an item list from are on our downloads page, and the dedicated MAF request page for lab equipment tenders takes the same details through a short form.
To request an authorisation letter, send us the tender reference number and issuing authority, the tender’s own MAF annexure if it prescribes one, the exact item list with the tender’s item numbers, your registered legal name and address as they appear on the bid, and the submission deadline together with the bid validity period. Tell us at the same time whether the buyer wants the letter notarised, sealed, or digitally signed, because that changes how long it takes to put in your hands.
We are quote based and publish no prices, so ask for the commercial offer in the same message. You will then have the authorisation and the costing together, which is the only way to be sure the models named in the letter are the models you are pricing.
If the offer changes after we issue the letter, whether because of a corrigendum, a pre-bid clarification, or your own substitution, tell us and we will reissue it against the revised list. That reissue is routine and it is a great deal cheaper than a technical rejection.
A last word for bidders. The MAF is a small document that decides whether the rest of your bid gets read. Ask for it early, keep the item list frozen, check the validity date against the deadline, and refresh it the moment your offer changes. Bids are lost on this paperwork far more often than they are lost on price.
If you are preparing a bid that includes our equipment and need an authorisation letter, or you want the specification checked against what we can actually supply before you commit to it, get in touch with our tender desk with the reference number and the item list.
One honest ask
We don't gate anything on this site. You just read the whole thing free. If it was useful, leave your email and two things happen: we send you this page as a plain-text block you can paste into a tender file or an internal email, and we notify you the next time we publish a buyer tool like this one. Nothing else. No drip sequence, no sales calls booked without asking.
