The usage of the coats of arms is regulated by Swedish Law, Act 1970:498 which states (in unofficial translation) that "in commercial activities, the coats of arms, the flag or other official insignia of Sweden may not be used in a trademark or other insignias for products or services without proper authorisation.

Any representation consisting of three crowns ordered two above one are considered to be the lesser coat of arms, and its usage is therefore restricted by law 1970:498.

The inescutcheon is party per pale the arms for the House of Vasa (Bendwise azure, argent and gules, a vasa Or); and the House of Bernadotte (Azure, issuant from a wavy base a bridge with three arches and two towers embattled argent, in honor point an eagle regardant with wings inverted resting on thunderbolts Or, and in chief the Big Dipper constellation of the same).

The stars were introduced as an element in the royal coat of arms in the 19th century,[5] chosen as a symbol of Sweden's eternal existence, as in the poem by Esaias Tegnér: As long as Charles's Wain still turns, Its golden wheels around the Northern zone, As long as the land still produces iron and heroes, Intact shall stand the ancient Swedish throne.

Supported by two lions regardant or crowned, with parted tails and armaments gules, standing on a postament.

The lesser coat of arms is mainly used by the Government of Sweden and subordinate State authorities.

As such it may be joined by insignias symbolising the activity of individual government agencies, following approval by the State Board of Heraldry.
