When product verification comes up, two different questions are often mistaken for one. The first is "Is this product really ours?", the second "Is this the product we declared?". Marking answers the first; analysis answers the second.
Marking: a signature is added to the product
In marking, a signature that can be read later is applied to the product or its surface. It can be luminescence-based and appear under the right light; DNA-based and seek an exact match in the lab; or magnetic and be read without contact through closed packaging.
The strength of marking is that it proves the product's source. A product inside copied packaging does not carry the signature and fails verification. But marking says nothing about the product's content: if a different oil has been filled into your own bottle, the bottle is still your bottle.
Analysis: the product itself is measured
In analysis, nothing is added to the product. A product accepted as genuine is measured once and kept as the reference; every later batch is measured the same way and compared with it.
This method is the only meaningful answer to problems such as dilution, adulteration and content that does not match the label. Olive oil blended with other oils, syrup added to honey or missing active ingredients in cosmetics cannot be spotted by looking at the packaging; you have to look at the product itself.
Which one, and when
What decides the choice is where the problem starts:
- If counterfeits enter the channel from outside, marking comes first. The product's source is verified on the spot at goods-in, in field audits or when reviewing returns.
- If the problem is inside the product, analysis is needed. Content is backed by measurement at raw material intake, at batch release or in the export file.
- If both appear together, the methods are layered: daily checks use a fast mark, and analysis comes in when there is a dispute or suspicion.
What information the decision needs
Choosing the right method means looking together at the product group, the production and filling flow, the points where verification will take place and who needs to hold the result. In most projects the first step is a feasibility study on a single product or batch.
