Distributor Authorization Letter
A distributor authorization letter (LOA) is a brand-signed document naming a company as an authorized distributor of its products — usually for a defined territory and term. Only the brand can issue it; you present it to regulators, marketplaces, and buyers as proof the products are brand-sanctioned.

What a distribution authorization letter is
When a brand appoints a company to distribute its products, third parties want proof. Regulators, marketplaces, tender committees, and retail chains all ask the same question: did the brand actually authorize this company? The distribution authorization letter answers it. It is a short document, signed by the brand owner or manufacturer, naming a specific company as an authorized distributor of specific products, usually in a defined territory and for a defined term.
The document travels under many names, and they all describe the same instrument: letter of authorization (LOA), distributor authorization letter, authorized distributor letter, brand authorization letter, manufacturer's authorization (the "MAF" of public tenders), and letter of appointment (the usual term in Gulf markets). In Philippine FDA filings, the related bilateral form is the Foreign Agency Agreement (FAA), filed in place of — or alongside — an LOA.
Know what it is not: a full commercial contract. The distribution agreement is the comprehensive private contract between brand and distributor — pricing, payment terms, minimum purchases, termination, dispute resolution. The letter is the short, third-party-facing attestation of that appointment, usually issued under the agreement so you never have to hand your whole contract to a regulator. Treat the letter as legal evidence of authorization rather than a substitute for the agreement, and have counsel review both before you sign.
On Grovara, the letter sits in the registration group of the export document stack — one of the papers buyers present to their import regulatory agency, alongside documents like the Certificate of Free Sale and the Certificate of Analysis.
The three situations that demand one
If you are the brand, you will be asked to issue this letter. If you are the buyer or distributor, you will be asked to present it. Three situations account for nearly all of the demand.
1. Foreign product registration — the most common trigger
Most import markets require the local registrant — the importer or distributor — to prove the foreign manufacturer authorized them before a product can be registered for sale. Mexico's COFEPRIS treats the letter as almost always mandatory, because the registration holder must be a Mexican legal entity; without a valid letter, the agency will not begin substantive review. The Philippine FDA requires a Foreign Agency Agreement or LOA from each foreign supplier. Vietnam and Indonesia require notarized, legalized letters before products can be notified or registered. Gulf regulators go further: Saudi Arabia's SFDA expects a notarized manufacturer authorization letter inside a full attestation chain, and Kuwait requires a legalized letter of appointment naming a sole or exclusive local agent.
For buyers, this letter is usually the first document your regulator asks you to obtain from the brand.
2. Marketplaces like Amazon
Amazon asks for a letter of authorization from the brand or rights owner — never from a distributor — when a seller lists a brand it does not own, when listings use the brand's intellectual property, or after an IP complaint. A missing or invalid letter can mean removed listings or a deactivated account. The letter must name the exact legal entity behind the Seller Central account, the marks, the marketplaces covered, and the term.
3. Tenders and retail onboarding
World Bank standard bidding documents and organizations such as IOM require a Manufacturer's Authorization Form: proof that the bidder may supply the manufacturer's goods and that the manufacturer extends its full warranty to goods offered under the bid. Outside formal tenders, retailers and customs authorities use brand authorization letters to screen out gray-market and counterfeit goods — portable evidence that the products in a shipment are brand-sanctioned.
What the letter must contain
Every element below exists because its absence gets letters rejected somewhere. Use this as your drafting checklist.
- Manufacturer's letterhead. Regulators, tender forms, and Amazon all expect the letter on the brand's letterhead — it visibly ties the grant to the issuer.
- Date and reference number. Tenders and registrars match the letter to a specific bid or dossier; an unreferenced letter is hard to file and easy to question.
- Both parties' full legal names and addresses, exactly as registered. Even a one-character mismatch against a business license or seller account is a top rejection reason — in Vietnam and on Amazon alike.
- The grant statement. The operative sentence — "We, [Manufacturer], hereby authorize [Distributor] to…" — is the first thing a reviewer looks for. Without it there is no authorization.
- Product scope. Name the products, SKUs, or model numbers. Vague "all products" wording triggers queries and rejections from regulators.
- Territory. State the country, region, or marketplace covered — for Amazon, the specific marketplace domains.
- Exclusivity statement. Say "exclusive" or "non-exclusive" explicitly. Kuwait requires the letter to state sole or exclusive agency, and silence invites disputes later.
- Term and validity. Give a start and end date, or "until revoked" with revocation mechanics. The filing date must fall inside the validity window.
- Authorized activities. List what the distributor may actually do: import, apply for and hold product registrations, respond to authority queries, sell and distribute, use the trademarks for those purposes, and provide after-sales support. Registrars check that the activity they are approving appears on the list.
- Warranty extension (tender variant). World Bank and IOM bidding forms require the manufacturer to extend its full guarantee and warranty for goods offered under the bid.
- Limitations. State that the distributor is an independent company, not an agent, and cannot bind the manufacturer — the standard line that keeps an authorization from being read as an agency.
- An authorized signature block. Name, title, and signature of someone with authority to bind the company — a director, officer, or holder of a power of attorney — plus the company seal where customary. A wrong signatory sinks the whole filing; Amazon also accepts a corporate-domain email or digital signature.
- Notarization and apostille or legalization, where required. Most foreign product registrations want the original letter notarized and then authenticated — the decision rule is two sections down.
- Certified translation, where required. Saudi Arabia's SFDA expects a certified Arabic translation; Vietnam requires a certified Vietnamese translation after legalization. Use a certified translator, not an in-house one.
Country requirements at a glance
Verified requirements by market. Rules change and vary by product category — confirm current practice with the authority or local counsel before you file.
| Market | What's required | Authentication level |
|---|---|---|
| Mexico — COFEPRIS | Letter of authorization to the Mexican registration holder, naming the products covered | Notarization + apostille; a missing or deficient letter halts review before it starts |
| Saudi Arabia — SFDA | Notarized manufacturer authorization letter in the registration dossier | Certified Arabic translation plus the full attestation chain (home chamber of commerce → home foreign ministry → Saudi embassy → Saudi foreign ministry); confirm current practice on apostille acceptance |
| UAE — municipal product registration | A UAE-licensed local agent or distributor registers the products | Attestation/legalization expected; confirm current practice with the emirate |
| Kuwait — Ministry of Health | Legalized original letter of appointment naming a sole or exclusive local agent | Consular legalization |
| Philippines — FDA | Foreign Agency Agreement (FAA) or LOA from each foreign supplier; add a supply or tripartite agreement if the supplier is not the manufacturer | Traditionally consularized; confirm current apostille practice |
| Vietnam — cosmetic notification | LOA stating scope, products, and validity; in Vietnamese or English | Notarization → consular legalization → certified Vietnamese translation |
| Indonesia — BPOM | LOA or agency appointment letter naming the importer/distributor (often expected to be exclusive) | Notarized, then apostilled or embassy-legalized |
| Public tenders (World Bank, IOM) | Manufacturer's Authorization Form on letterhead, signed under power of attorney, referencing the bid and extending the warranty | Proof of signature authority; notarization per tender rules |
| Amazon | LOA from the brand owner naming the exact Seller Central entity, the marks, the marketplaces, and the term | Brand letterhead plus an authorized signatory, corporate-domain email, or digital signature |
Notarization, apostille, or consular legalization?
The decision rule takes two sentences. If both the brand's country and the destination country belong to the Hague Apostille Convention, notarize the letter and obtain a single apostille certificate — that is the entire chain. If either country is not a member, you need consular legalization instead: notarization, then authentication by the origin country's foreign ministry, then legalization by the destination country's embassy.
Check current membership on the HCCH Apostille Convention page. Two follow-on rules: file originals, not copies — most registrars reject photocopied or scanned authentication — and where a certified translation is required (Arabic for Saudi Arabia, Vietnamese for Vietnam), it comes after the authentication step, from a certified translator.
Exclusive vs. non-exclusive: read before you sign
An exclusive authorization bars the brand itself and every other distributor from the covered territory or segment. A non-exclusive authorization leaves the brand free to appoint other distributors or sell direct. "Authorized" does not mean "exclusive" — the letter grants only what it says.
Here is the trap. Some registrars expect, or require, sole or exclusive agency language: Kuwait's letter of appointment must name a sole or exclusive local agent, and Indonesian registration guides often describe the appointment as exclusive. Brands eager to unblock a registration sign whatever is put in front of them — and sleepwalk into exclusivity. A poorly scoped exclusive grant can lock you out of a territory for the entire term, even if the distributor never sells a unit.
If a regulator requires exclusivity wording, scope it tightly: name the exact products and channel, keep the term short, and tie renewal to performance in the underlying distribution agreement. Have counsel review any exclusive grant before you sign it.
Common mistakes that get letters rejected
These are drawn from real rejection reasons reported by regulators, registration consultants, and marketplace reviewers.
- Entity-name mismatch. Even a one-character difference between the letter and the business license, seller account, or dossier gets the filing rejected.
- A vague grant. "All products," with no SKUs, lines, or marks named, triggers queries and rejections in Mexico, Vietnam, and Indonesia.
- No term or territory. An open-ended letter gives the reviewer nothing to verify — and gives you no way to contain the grant.
- Accidental exclusivity. Signing "sole and exclusive" language just to satisfy a registrar can block the market for the whole term.
- The wrong signatory. If the person signing lacks authority to bind the manufacturer, the letter fails no matter how well it is drafted.
- A broken authentication chain. Skipping or mis-sequencing notarization and legalization, filing copies instead of originals, or filing with expired stamps.
- Stale letters. Filing outside the letter's validity window — and undated letters may only be accepted briefly, if at all.
- The distributor writing its own letter. Only the brand owner can grant authorization; a self-issued letter is a top marketplace rejection reason.
- Uncertified or mismatched translations. A translation that is uncertified, or that does not match the authenticated original, fails the dossier.
- Treating the letter as the whole deal. The letter proves the appointment; the distribution agreement governs it. Without the agreement, you have no pricing, termination, or dispute terms to fall back on.
Related documents
The authorization letter rarely travels alone. Here is how it differs from the documents most often filed beside it.
- Distribution agreement — the full bilateral contract covering pricing, payment, IP license, minimum purchases, and termination; the letter is the short attestation issued under it for third parties.
- Certificate of Free Sale — certifies the product is legally sold in its home market. It speaks to the product's status, not the distributor's rights, and is often filed alongside the letter.
- Power of attorney — grants authority to perform legal acts on the issuer's behalf; some regulators require both a POA and an authorization letter in the same dossier.
- Foreign Agency Agreement (FAA) — the Philippine FDA's bilateral-contract counterpart to the LOA.
- Manufacturer's Authorization Form (MAF) — the tender variant, tied to a specific bid and extending the manufacturer's warranty.

Frequently asked questions
Who issues a distributor authorization letter?
The brand owner or manufacturer issues it — never the distributor itself. A letter a distributor writes on its own behalf is a top reason marketplaces and regulators reject applications.
Is a distributor authorization letter legally binding?
It is legal evidence of authorization, and its enforceability depends on how it is drafted — it does not replace a distribution agreement. Have counsel review any letter before you sign or file it.
Does an authorization letter need to be notarized?
Not for ordinary business use or Amazon, but most foreign product registrations require the letter to be notarized and then apostilled or consular-legalized.
What is the difference between an authorization letter and a distribution agreement?
The distribution agreement is the full private contract between brand and distributor; the letter is the short proof of appointment you show third parties. The letter is usually issued under the agreement, not instead of it.
How long is a distributor authorization letter valid?
Exactly as long as it says — a stated date range, or until revoked in writing. Your filing date must fall inside the validity window, and some authorities reject undated letters outright or accept them only for a short window.
Can a distributor authorization letter be revoked?
Yes — generally by written notice to the distributor and to any organization relying on the letter, subject to the terms of the underlying agreement. Ask counsel before revoking, because the distribution agreement may survive the letter.
Do I need a letter of authorization to sell on Amazon?
You need one when you sell a brand you do not own, when your listings use the brand’s intellectual property, or after an IP complaint. It must come from the brand owner and name the exact legal entity behind your Seller Central account.
Does an authorization letter make me the exclusive distributor?
Only if it explicitly says "exclusive" — "authorized" does not mean "exclusive." If the letter is silent, assume the brand can appoint other distributors or sell direct.
What is the difference between an apostille and consular legalization?
An apostille is a single certificate that authenticates the notarized letter between Hague Convention member countries; consular legalization is the multi-step embassy chain used when either country is not a member.
Can I appoint sub-distributors with an authorization letter?
Only if the letter expressly grants that right — assume you cannot unless it says so. Confirm with the brand and with counsel before extending the chain.
