Authenticity is the defining quality question in the international honey trade. Buyers increasingly expect suppliers to address adulteration risk head-on, with structured screening rather than assurances. This primer summarises the landscape without the laboratory jargon.
What C4 screening addresses
Classical isotope-ratio methods screen for the addition of C4-plant sugars such as cane or corn syrup. They are a long-established baseline in honey trade and remain a standard element of many purchase specifications.
Where advanced methods fit
Because some adulterants are not visible to C4 methods alone, buyers in certain markets additionally request advanced analyses, including high-resolution mass spectrometry based approaches, through specialised laboratories. Which methods apply — and at whose cost — is a commercial point that belongs in the contract.
The supplier's role
A credible supplier controls authenticity risk at sourcing: knowing the beekeeping regions, evaluating incoming lots, and maintaining traceability from procurement to dispatch. Laboratory screening then verifies what disciplined sourcing has already protected.
Practical advice: define the authenticity testing scope in the specification, name the reference laboratories both parties accept, and agree how results are reported. Clear rules before shipment prevent disputes after arrival.
