While the seal, which used in legal transactions, is defined in details in the same Article, the other symbols are adopted by the Assembly. The HGZD symbols were made after the establishemt of the Association in 2006 and they were first presented to the international professional public at the 22nd International Congress of Vexillology in Berlin, 6 through 10 August 2007, and they were confirmed by the HGZD Assembly of 2 October 2007.

The shield is encircled with a ribbon forming rotated square with rounded vertexes azure bordered or forming four vexillological knots and inscribed within it above HGZD and below 2006. To the dexter passing through the ribbon a staff or and on it attached a swallow-tailed flag trierced gules-argent-azure with a square rotated patch argent overall containing the same escutcheon and the ribbon.

- the vexillological knots are international symbols of vexillological studies, and
- the flag in the shield is a symbol of flag purport.
The colours, patterns and shapes link the symbols with the Croatian herladic and vexillological heritage:
- The choice of basic colours of the coat of arms and the flag, red/gules, silver/argent i blue/azure, links them with the Croatian national colours,
- the herald’s baton is chequred red-silver/gules-argent symbolizing the Croatian heraldic heritage, while
- the swallow-tailed flag is shaped like the first Croatian tricolour, used by Ban Jelačić in 1848, which was also with a split fly.
