Certifications, and the one question each answers.

A honey label can carry five badges and still leave the thing you care about unverified. The trick is not collecting certifications — it is knowing which question each one actually answers, and which it cannot.

10-min read · Updated June 2026

Walk a honey aisle and you will see USDA Organic next to UMF, MGO, KFactor, and a scatter of unregulated words — Raw, Pure, Unpasteurized. They look like a single ladder from ordinary to excellent. They are not a ladder.

Each certification was built to answer a different question — Was it produced cleanly? Is it genuinely from where it claims? How much of a marker compound is in it? How little was it processed? A badge is only useful once you know which of those questions it speaks to, and which it stays silent on. Read them that way and the aisle gets simple: match the badge to the question you actually have.

The Comparison

What each certification actually verifies

Read across, not down. The columns are independent — a certification can be rigorous on origin and silent on processing, or the reverse.

No single badge answers every question. A certification can be rigorous on origin and silent on processing, or vice versa — which is why the columns matter more than the count of seals.

The five badges, one by one
The unregulated words

“Raw,” “Unpasteurized,” and “Pure” are descriptions, not certifications.

“Raw” generally means the honey was not heated above a stated threshold (often cited near 118°F, though it varies), which is meant to preserve enzymes and pollen. “Unpasteurized” means it skipped the standard high-heat step some large producers use. “Pure” implies nothing was added. All three are useful as intent — but none is independently tested or defined by a certifying body, so any of them can appear on a label without verification behind it. They are most trustworthy alongside a producer you already trust, or paired with a measured signal like KFactor that puts a number on the processing claim.

Decision aid

Which badge for which honey

Match the certification to the honey in your hand — the right seal depends on what is most likely to be misrepresented.

If
Manuka — among the most-mislabeled honeys in the world.
Then
UMF (or MGO) — essential
The authenticity question is the whole game here. Favor UMF, which pairs grading with pollen authentication; treat manuka with no explicit UMF or MGO result with skepticism. True Source adds further origin assurance.
If
Single-origin / monofloral — sold on the strength of one floral source.
Then
True Source Certified
Its pollen analysis confirms the claimed floral source — the strongest signal for this category. KFactor adds a processing read if minimal handling matters to you.
If
Raw — a processing claim with no legal definition.
Then
KFactor + True Source
KFactor gives an objective read on pollen and processing; True Source confirms authenticity. Organic is meaningful only if production practice is your priority — it says nothing about processing level.
If
Multifloral / blended — the most vulnerable category to verify.
Then
True Source Certified
Mixed pollen makes origin hard to verify. Lean hardest on True Source here, and be wary of ultra-filtered blends, where pollen removal can hide the sources.
Verification depth

How many questions are answered

Not a ladder of spend — a ladder of certainty. Each rung up adds an independent, separately-tested answer.

↑ More verified
05
Multiply verified
Authentic origin + graded marker + transparent processing, each from its own test.
04
Authenticated and graded
Origin plus a measured marker — e.g. UMF, which pairs both.
03
Origin verified
Adulteration and source confirmed — e.g. True Source.
02
Single answer
One question verified — e.g. Organic alone: inputs only.
01
Unverified
Label claims only, no independent check.

More badges help only when they answer different questions. Three certifications that all verify the same thing add less than two that cover origin and processing.

Reading the label

A real certification leaves traces you can check.

A certification number or code, the issuing organization or testing lab, and often a date — since certifications expire and renew. UMF honey should show a specific number (UMF 15+) and ideally the MGO value beside it. True Source products carry a logo and a code verifiable on the True Source registry. When a honey leans on its certification as the reason to choose it, spending thirty seconds verifying that certification on the issuer's site is the single most useful check a shopper can do.

A certified honey is a verified honey — not necessarily one you will like.
The Melvea posture

Every badge on this page answers a question about origin, authenticity, or processing. None of them answers whether the honey suits your palate. That question is the one Melvea is built to help you answer — and it is a different kind of certainty entirely.

Common questions
Is organic honey better than non-organic?+

Not necessarily — “better” depends on your question. Organic verifies how the honey was produced (no prohibited inputs), not whether it is authentic or minimally processed. For purity of source, look to True Source; for processing, KFactor.

Does a UMF number tell me how good the manuka is?+

It tells you the honey is genuinely manuka and grades its MGO level against a standard. Read it as a verified grade of a real manuka honey — not as a measure of what the honey will do for you.

What is the difference between UMF and MGO?+

MGO measures one compound directly, in milligrams per kilogram. UMF grades the same compound and pairs it with pollen analysis confirming authentic manuka — so UMF answers the authenticity question that MGO alone does not.

Is “raw” honey certified?+

No. “Raw,” “unpasteurized,” and “pure” are descriptions without an independent testing body behind them. KFactor is the closest objective stand-in for the processing claim “raw” implies.

Why would honey have its pollen removed?+

Ultra-filtration produces a clear, slow-to-crystallize product — but it also strips the pollen used to verify origin. The result can be perfectly good honey whose source can no longer be confirmed.

How do I verify a certification is real?+

Look for a code or number, the issuing body, and a date, then check it on the issuer's website — True Source and UMF both maintain registries. A printed logo alone is not proof.

If I can only look for one thing, what should it be?+

For manuka, a UMF number. For everything else, True Source Certified — it answers the origin-and-adulteration question most shoppers actually have.
