How to choose a reliable olive oil supplier

Q: How do you recognise a reliable olive oil supplier?

Short answer: a reliable supplier proves its identity and licence (registered company, ONH export licence in Tunisia), provides a per-lot COA from an IOC-approved laboratory, holds the certifications suited to your market and channel (organic Ecocert, IFS/BRC for large retail…), agrees to provide a reference sample and offers a clear cont

Q: How do you verify that an olive oil supplier is reliable?

Verify its identity and licence (registered company, customs code, ONH export licence), require a per-lot COA from an IOC-approved laboratory, check its certifications (organic, IFS/BRC) via their numbers, request a reference sample and a clear contract . A serious supplier provides all this without reluctance.

Q: What documents should you ask a supplier before ordering?

At a minimum: proof of export licence and customs code, lot COA (IOC-approved lab), verifiable certification numbers (organic Ecocert, IFS/BRC per channel), a sealed reference sample , and a contract specifying incoterm, port, MOQ, tolerances and payment terms.

Q: What is a COA and why require it?

The COA (certificate of analysis) certifies the oil's category (acidity, peroxide, K232/K270, sometimes polyphenols) per lot, via an IOC-approved laboratory . It is your proof that the stated extra virgin does have an acidity ≤ 0.80%. Without a COA, the category is not proven. Interpret it with the quality classifier.

Q: What are the main red flags of a supplier?

Refusal to provide a COA, a price well below the market without explanation, vague licence or identity, requirement of a 100% upfront payment to a third-party account, refusal of a sample, absence of a written contract, and unverifiable certifications. A single one of these points warrants reinforced verification.

Q: Should you request a sample before ordering?

Yes, systematically. A sealed and dated reference sample lets you validate the profile and hold a proof in the event of a dispute on arrival. A supplier who refuses the sample, or whose sample doesn't match the delivered lot, is a warning sign.

Q: Which certifications should a supplier have?

It depends on your market and channel : organic Ecocert if you claim organic, IFS/BRC for large retail and private label, HACCP/ISO 22000 per industry, FDA/FSVP for the USA. Certification follows the outlet — see certifications & quality.

Q: How do you secure payment with a new supplier?

Avoid 100% upfront to an unverified supplier. Favour a confirmed LC (documentary credit) or payment against documents , possibly a reasonable deposit + balance at shipment. A supplier who refuses any payment security should alert you.

Q: How do you verify a Tunisian exporter's licence?

Request proof of the ONH export licence and the company's customs code . An exporter can also operate under a partner's licence through a commission agreement — in that case, ask to identify the actual approved exporter. An unverifiable company is a major red flag.

You are looking for an olive oil supplier to import, bottle or launch your brand — and you want to avoid the bad lot, the ghost exporter or the dispute on arrival? This guide gives the objective selection criteria, the red flags that should make you flee, the questions to ask and a ready-to-use due diligence checklist. Detailed buyer's angle, with a "how to be that supplier" box on the seller's side. Tables, mistakes to avoid and checklist included.

How do you recognise a reliable olive oil supplier?

Short answer: a reliable supplier proves its identity and licence (registered company, ONH export licence in Tunisia), provides a per-lot COA from an IOC-approved laboratory, holds the certifications suited to your market and channel (organic Ecocert, IFS/BRC for large retail…), agrees to provide a reference sample and offers a clear contract (incoterm, tolerances, secure payment). The absence of any of these elements is a warning sign.

Choosing a supplier means arbitrating between price, quality, documentary reliability and payment security. An abnormally low price often hides a problem of category, traceability or solvency. The technical terms (COA, EUR.1, IFS/BRC, incoterm, MOQ…) are defined in the glossary.

The selection criteria for a supplier

Assess each supplier on these seven axes. A serious supplier passes every point without reluctance.

Criterion	What to verify	Why it's decisive
Identity & legality	Registered company, customs code, ONH export licence	An unlicensed exporter cannot ship legally
Quality & traceability	Per-lot COA (IOC-approved lab), lot no., real category	Guarantees the stated category (extra virgin = acidity ≤ 0.80%)
Certifications	Organic (Ecocert), IFS/BRC, HACCP/ISO per channel	Large retail requires IFS/BRC; organic requires Ecocert
Capacity & regularity	Available volume, campaign, milling capacity	A supplier out of stock won't meet its deadlines
Documentary	Command of EUR.1/CO, packing list, consistent B/L	An inconsistent file blocks the container at port
Commercial	Clear incoterm, MOQ, tolerances, responsiveness	A vague or implicit incoterm = margin dispute
Financial	Reasonable payment terms, open to the LC	Refusing any payment security is a red flag

Verify the stated category yourself from a COA with the quality classifier, and the completeness of the file with the documentary checklist.

Key point: never judge a supplier on price alone. The winning trio is reliable COA + suitable certifications + secure payment. What's missing from the file is what will cost you on arrival.

Box: buyer's side / seller's side

The same subject reads both ways — knowing how to choose, or knowing how to be the right supplier.

Angle	What "choosing a supplier" changes for you	Reflex
Buyer (importer)	You must filter suppliers and secure your order	Require per-lot COA, certifications, sample and payment against documents/LC
Seller (selling exporter)	You must reassure the buyer and shorten their decision cycle	Present upfront the licence, COA, certifications and references
Exporter (Tunisia operations)	Your credibility rests on an impeccable file	Anticipate EUR.1, organic certification and documentary consistency

How to be that supplier (seller/exporter side)

Want to be chosen? Reverse the buyer's checklist and get ahead of their questions:

Present without being asked: ONH export licence, registration, recent COA from an IOC-approved lab, certifications (organic Ecocert, IFS/BRC per target channel).
Offer a sealed and dated reference sample — that is the gesture that installs trust.
Quote with a precise incoterm and port ("FOB Radès"), an MOQ and written tolerances.
Accept a confirmed LC or payment against documents: refusing any security scares off the serious buyer.
Document your regularity (campaigns, capacity) rather than promising the impossible.

Learning to structure this offer (file, quotation, contract) is part of the export training and the private label support.

Red flags: warning signs not to ignore

Direct answer: flee a supplier who refuses to provide a per-lot COA, shows a price well below the market without explanation, stays vague about its licence or identity, requires a 100% upfront payment to a third-party account, or wants no sample and no written contract. Each of these points, alone, warrants reinforced verification; combined, they signal a scam or a dispute.

No COA or a COA without an identified / IOC-approved laboratory.
Abnormally low price vs the market benchmark: often a lower category (virgin/lampante sold as extra virgin).
Vague licence/identity: no verifiable company, no customs code, evasive address.
100% upfront payment required, to a personal account or in a country unrelated to the exporter.
Refusal of a sample or a sample that doesn't match the delivered lot.
Absent or vague contract: implicit incoterm, no tolerances, no quality recourse.
Closing pressure ("last container available") without verifiable justification.
Unverifiable certifications: logos displayed but no certificate number checkable with the body.

A real urgency (end of campaign, EU quota nearly exhausted) is a verifiable fact. A manufactured pressure without proof is a warning sign, not an argument.

The questions to ask before ordering

Ask these questions from the first contact. The answers (and the way they are given) sort suppliers.

Are you licensed to export (ONH licence)? Can you provide your customs code?
Can I receive a lot COA issued by an IOC-approved laboratory?
What is the exact category (extra virgin, virgin…) and the measured acidity of the lot?
Which certifications do you hold (organic Ecocert, IFS/BRC, HACCP) and what verifiable numbers?
Can you send a sealed and dated reference sample?
Which incoterm do you offer, and from which port (Radès, Sfax)?
Which packaging (flexitank, IBC, drum) and what MOQ?
What payment terms? Do you accept a confirmed LC / payment against documents?
What contractual tolerances (acidity, weight, deadline) and what recourse in case of a discrepancy?
What is your capacity and regularity for the current campaign?

Interpret the COA answer (acidity, peroxide, K232/K270, polyphenols) with the quality classifier.

Mistakes to avoid when choosing a supplier

Choosing on price alone: a low price often hides a lower category or a solvency risk.
Skipping the COA: without a per-lot certificate of analysis, the stated category is not proven.
Ignoring the channel's certifications: ordering without IFS/BRC when large retail requires it = a product unsellable on the shelf.
Paying 100% upfront to an unverified supplier: the most common scam risk.
Not requesting a sample: the reference sample is your proof in the event of a dispute.
Accepting a vague incoterm: "FOB" without a port, no tolerances = a programmed margin dispute.
Confusing real urgency and pressure: verify any scarcity argument.
Neglecting documentary origin: a supplier who doesn't master the EUR.1 makes you lose the EU customs advantage.

Golden rules

Per-lot COA, always — from an IOC-approved laboratory.
Certifications aligned with your market and channel (organic, IFS/BRC…).
Reference sample sealed and dated before a firm order.
Written contract: incoterm + port, MOQ, tolerances, quality recourse.
Secure payment: never 100% upfront to a stranger; favour the confirmed LC or payment against documents.
Verify, don't take it on trust: identity, licence, certificate numbers.

FAQ — Choosing an olive oil supplier

How do you verify that an olive oil supplier is reliable?

Verify its identity and licence (registered company, customs code, ONH export licence), require a per-lot COA from an IOC-approved laboratory, check its certifications (organic, IFS/BRC) via their numbers, request a reference sample and a clear contract. A serious supplier provides all this without reluctance.

What documents should you ask a supplier before ordering?

At a minimum: proof of export licence and customs code, lot COA (IOC-approved lab), verifiable certification numbers (organic Ecocert, IFS/BRC per channel), a sealed reference sample, and a contract specifying incoterm, port, MOQ, tolerances and payment terms.

What is a COA and why require it?

The COA (certificate of analysis) certifies the oil's category (acidity, peroxide, K232/K270, sometimes polyphenols) per lot, via an IOC-approved laboratory. It is your proof that the stated extra virgin does have an acidity ≤ 0.80%. Without a COA, the category is not proven. Interpret it with the quality classifier.

What are the main red flags of a supplier?

Refusal to provide a COA, a price well below the market without explanation, vague licence or identity, requirement of a 100% upfront payment to a third-party account, refusal of a sample, absence of a written contract, and unverifiable certifications. A single one of these points warrants reinforced verification.

Is a very low price a good sign?

Rarely. A price clearly below the market benchmark often hides a lower category (virgin or lampante sold as extra virgin), a traceability flaw, or a solvency risk. Price should be read together with the COA and the certifications.

Should you request a sample before ordering?

Yes, systematically. A sealed and dated reference sample lets you validate the profile and hold a proof in the event of a dispute on arrival. A supplier who refuses the sample, or whose sample doesn't match the delivered lot, is a warning sign.

Which certifications should a supplier have?

It depends on your market and channel: organic Ecocert if you claim organic, IFS/BRC for large retail and private label, HACCP/ISO 22000 per industry, FDA/FSVP for the USA. Certification follows the outlet — see certifications & quality.

How do you secure payment with a new supplier?

Avoid 100% upfront to an unverified supplier. Favour a confirmed LC (documentary credit) or payment against documents, possibly a reasonable deposit + balance at shipment. A supplier who refuses any payment security should alert you.

Request proof of the ONH export licence and the company's customs code. An exporter can also operate under a partner's licence through a commission agreement — in that case, ask to identify the actual approved exporter. An unverifiable company is a major red flag.

Which questions should you ask a supplier as a priority?

Licence and customs code? Lot COA from an IOC-approved lab? Exact category and acidity? Verifiable certifications? Reference sample available? Incoterm and port? Payment terms and openness to an LC? Tolerances and quality recourse? These answers quickly sort out the serious suppliers.

How can an exporter become a chosen supplier?

By getting ahead of the buyer's questions: presenting upfront the licence, a recent COA, certifications suited to the channel, offering a reference sample, quoting with a precise incoterm and port, and accepting a confirmed LC. Documentary transparency shortens the sales cycle. See the "how to be that supplier" box above.

How do you tell a fake urgency from a supplier?

A real urgency rests on a verifiable fact (end of campaign, EU quota nearly exhausted, limited shipping line). A manufactured urgency ("last container", "price valid today only") without proof is a pressure technique: request the justification, and be wary if it doesn't come.
