Our electronic ear tags are ICAR approved. This means that they satisfy international standards for electronic identification of farm animals – ISO 11784 and ISO 11785. This also means that the ear tags are compatible with electronic scales, reading equipment and other installations that comply with the standards.

Safe tagging

Combi tags are Europe’s most popular tagging system for farm animals. For livestock owners and other participants in the production chain, Combi tags are a sign of quality. They safeguard the animal’s identity from birth to slaughter enabling traceability and documentation throughout the whole value chain. CombiE tags are approved as official means of identification in many countries in several parts of the world.

Secure locking system

Combi tags have a special strong locking mechanism. The unique locking principle has been patented and re-use of the tag is impossible. The lock contains no metal parts and may be recycled. Patent no. 304771.

Optimum retention

Combi tags are made from a soft and flexible special plastic compound which can tolerate significant temperature variation, sunlight and extreme wear and tear throughout the life of the animal. The material and shape ensure a secure fit.

Laser printing

Numbers and letters are printed by laser into the plastic tag and are clear and easy to read. The print lasts for the duration of the animal’s life.

Simple, animal-friendly application

The tags are applied with Combi Junior or Combi Matic applicator. The surface of the wound heals quickly. An enclosed shaft tip prevents contagion.

Ultrasonic welding

We are the only manufacturer to use ultrasonic welding to attach readymanufactured CombiE ear tags. The method is both environmentally and user friendly, making cardboard and tape redundant. The female and male tag parts are welded together into one strip and the tags are released in one simple hand movement. Patent no. 320230.


CombiE ear tags are supplied in three different sizes and meet the requirements for the tagging of cattle, sheep, goats, pigs and deer.
