Not every Manuka honey product uses a UMF rating — and that’s completely normal.
If you’ve been browsing Manuka honey online or on Amazon, you’ve probably seen jars labelled UMF 10+, UMF 15+, or just MGO 250+, MGO 400+, or higher. It can feel confusing at first, especially when you’re trying to choose the best option for your needs.
Here’s the key takeaway:
A jar without UMF is not automatically lower quality — many excellent Manuka honey products use MGO or other systems instead.
In fact, some of the most popular and best-selling Manuka honey products today use MGO ratings only, making them easier to compare and often more accessible in price.
The smart approach is not to avoid non-UMF products — it’s to understand what they offer so you can confidently choose the right one.
Seeing Manuka honey with no UMF rating? 🔎
UMF stands for Unique Mānuka Factor, a certification system developed in New Zealand.
According to the UMF Honey Association, UMF verifies authenticity, potency, purity, and freshness. That makes it a trusted system — especially for buyers who want a structured and certified label.
But here’s where many buyers get stuck:
UMF is just one system — not the only way to measure quality.
Many high-quality Manuka honey products use:
- MGO (methylglyoxal) as a clear strength indicator
- Australian authenticity systems
- Brand-specific grading systems like MGS or KFactor
- Or are sold in formats like lozenges, gummies, or skincare
Because of this, you’ll often find excellent products that don’t carry UMF — especially on major marketplaces.
Instead of skipping them, ask:
What does this product use instead of UMF — and does it clearly show quality?
Why a product may use MGO instead of UMF 🔢
One of the most common reasons a Manuka honey product does not show UMF is simple:
It uses MGO instead — and that’s often easier for buyers.
MGO (methylglyoxal) is the compound responsible for Manuka honey’s unique properties. You’ll typically see it labelled like:
- MGO 100+
- MGO 250+
- MGO 400+
- MGO 800+
The higher the number, the stronger the concentration.
While UMF includes multiple factors (like leptosperin, DHA, and HMF), many brands choose MGO because:
- It’s easy to understand at a glance
- It’s widely used across both New Zealand and Australian products
- It allows quick comparison between jars when shopping online
For many buyers, especially beginners, MGO-labelled honey is actually simpler and more practical to choose from.
That said, it’s still important to check a few key details before buying.
If a jar does not show UMF, look for:
- A clear MGO number
- Evidence of lab testing
- Country of origin
- Whether it’s monofloral or multifloral
- Batch numbers or traceability
- Brand transparency and reputation
When these are present, MGO-only products can be an excellent choice — and often better value.
Manuka honey products without UMF compared 📊
| Label situation | Why UMF may not appear | What buyers should check | What not to assume |
|---|---|---|---|
| MGO-only Manuka honey | Brand uses methylglyoxal as the main strength label | MGO number, testing, origin, batch details | No UMF does not mean low quality |
| Australian Manuka honey | Uses Australian authenticity systems | Country, MGO, DHA, AMHA details | Not inferior to NZ honey |
| MGS-rated Manuka honey | Brand uses another grading system | Explanation of MGS and testing | Not directly comparable to UMF |
| KFactor Manuka honey | Brand uses a different label system | What KFactor measures, MGO presence | Not a strength rating like UMF |
| Lozenges, drops or gummies | Contains Manuka honey as an ingredient | Ingredient list, honey content | Not equal to pure honey jars |
| Skincare product | Cosmetic use of Manuka honey | Ingredients and intended use | Not edible honey |
| Vague “active” label | No clear recognised system | Look for MGO or testing proof | “Active” alone is not enough |

What to check if there is no UMF rating ✅
When buying Manuka honey without UMF, think of it as a quick checklist rather than a warning sign.
Start with the basics:
- Does it clearly show an MGO rating?
- Is the country of origin listed?
- Does it mention lab testing or batch numbers?
- Is it labelled monofloral or multifloral?
If it’s Australian Manuka honey, check whether it refers to authenticity standards. The Australian Manuka Honey Association explains its testing criteria — you can read more here.
If it’s New Zealand honey, remember that exported mānuka honey must meet strict scientific definitions set by the Ministry for Primary Industries — you can read more here.
These systems help ensure authenticity even when UMF is not used.
From a buyer’s perspective, this means:
You can confidently choose non-UMF Manuka honey — as long as the label is clear and transparent.
Five reasons a Manuka honey product may not show UMF 📌
The brand uses MGO as its main rating 🔢
Many top-selling Manuka honey products use MGO because it’s simple and effective.
If you’re comparing jars online, seeing MGO 250+ vs MGO 400+ is often easier than interpreting multiple grading systems.
For most buyers, this makes MGO-labelled honey a practical and reliable choice.
The product is Australian Manuka honey 🇦🇺
Australian Manuka honey is widely available and often competitively priced.
It typically uses MGO-based labelling and Australian authenticity standards rather than UMF.
This gives buyers more options — especially when looking for value without sacrificing quality.
The brand uses another system such as MGS or KFactor 🏷️
Some brands use their own grading systems.
These can still represent quality, but it’s best when they also include MGO numbers or testing details so you can compare easily.
The product is not a pure jar of Manuka honey 🍬
Products like lozenges, gummies, and skincare often contain Manuka honey but are not pure honey.
These can still be useful depending on your needs, but they should not be compared directly with jar honey.
The brand is not licensed to use the UMF mark 🧾
UMF certification requires licensing.
Some brands choose not to participate — not necessarily because of quality, but due to cost or branding decisions.
That’s why many reputable products rely on MGO instead.
FAQs about Manuka honey with no UMF rating ❓
Does no UMF rating mean Manuka honey is fake?
No. Many genuine and high-quality products use MGO or other systems instead. Just make sure the label clearly shows testing and origin.
Is MGO-only Manuka honey still useful to compare?
Yes — and often easier. MGO gives a clear strength number, making it simple to compare products quickly when shopping.
Why do Australian Manuka honey products often not use UMF?
Because UMF is a New Zealand certification system. Australian products use their own authenticity standards and MGO labelling.
Should I avoid Manuka honey with no UMF rating?
No. Many excellent products don’t use UMF. Focus on clear labelling, MGO levels, and trusted brands instead.
Is non-UMF Manuka honey medical-grade?
No. Food-grade honey is not the same as medical-grade honey. Always use products as intended.
Final thoughts: no UMF means more choice — not less ✅
UMF is a trusted system, but it’s not the only way to find high-quality Manuka honey.
In fact, many of the most popular and best-value options today use MGO ratings instead, giving you:
- Easier comparisons
- More price flexibility
- A wider range of products to choose from
The key is simple:
Look for clear labelling, strong MGO levels, and transparent brands — and you’ll be in a great position to choose a product worth buying.
