Pickup a jar of Manuka honey and the label can feel like a lot to interpret. UMF. MGO. Certification marks. Batch numbers. Country of origin. Here’s what each element actually tells you — and what to do if something is missing.
The UMF™ mark and number
The UMF™ logo is the most important thing to look for. It stands for Unique Mānuka Factor and it’s a trademarked certification mark issued by the UMF Honey Association in New Zealand.
A jar carrying the UMF™ mark has been independently tested by an accredited laboratory. The number beside the mark — UMF 10+, UMF 15+, UMF 20+ — reflects the independently verified concentration of three specific Manuka markers: leptosperin, DHA, and MGO.
What to check: The official UMF™ logo, not just the letters. And the number alongside it. Without both, the jar has not been through full UMF™ certification.
What the number means: Higher numbers indicate higher certified concentrations of Manuka markers and a richer, more intense flavour. See our grade guide for a full breakdown.
The batch number
The batch or lot number is a traceability identifier. Every jar of UMF™-certified Manuka honey should have one.
The batch number connects that specific jar to the test results, season, and hive location it came from. At Happy Valley, every batch number traces back through our records to the specific harvest it came from.
What to check: There should be a batch or lot number somewhere on the jar — usually on the base or back label. If there isn’t one, traceability is limited.
Country of origin
Genuine Manuka honey is produced in New Zealand. The label should state “Product of New Zealand” or “Produced in New Zealand” clearly.
Vague origin claims — “New Zealand quality” or “New Zealand inspired” — are not the same as clear country-of-origin labelling. If you’re buying in the US, this is worth checking carefully.
The producer name
Who actually made this honey? Some brands are the producer — they own hives, extract honey, and sell directly. Others are sourcing brands that buy bulk honey and apply a label.
Both are legal. But understanding which type you’re buying from tells you something about traceability and accountability. A vertically integrated producer like Happy Valley can tell you exactly where the honey came from. A sourcing brand may have limited visibility into the supply chain.
What a good label looks like at a glance
UMF™ logo - Official mark, not just the letters
Grade number - Displayed clearly alongside the logo
Batch number - On the jar, usually base or back
Country of origin - “Product of New Zealand”
Net weight - Clearly stated
Producer name - Identifiable brand with traceable history
A note on label claims
Under New Zealand and Australian food standards, honey cannot carry health claims on the label. Legitimate Manuka honey labels focus on certification, origin, and grade — not on what the honey will do for you. If a label makes specific health or therapeutic claims, that’s a red flag rather than a selling point.
