The plans resolve a concussion lawsuit filed against the federation by parents but US Soccer said it had planned to introduce a new safety campaign.
They also intend to limit the amount of heading in practice for children between the ages of 11 and 13.
"Although these are recommendations, they are based on the advice of the US Soccer medical committee," it said.
"Therefore US Soccer strongly urges that they be followed."
The lawsuit filed by young players and their parents in August 2014 accused governing bodies, including Fifa and the California Youth Soccer Association, of acting "carelessly and negligently" and failing to protect young players.
US Soccer said the reforms would also include "modifications to substitution rules in relation to concussions" and would be "requirements for players that are part of US Soccer's youth national teams and the development academy."
It added: "Protecting the health and safety of athletes and preventing injuries is critically important to US Soccer."
There has been previous criticism of football's attitude towards concussions but new rules have been brought in for Premier League matches after Tottenham goalkeeper Hugo Lloris continued playing after he lost consciousness.
Following those measures Dr Michael Grey, a leading neuroscientist from the University of Birmingham, said it was dangerous for children to head a football.
The Football Association offer no specific guidance for children heading footballs in England but said it had "noted the new rule changes outlined by US Soccer and will closely monitor any available new research in this area".
The FA also said it would shortly announce new guidelines formed by an independent expert panel "which look at how to identify, manage and treat suspected head injuries and to manage a player's safe return to play at all levels of football".
It added: "However, they do not relate to how football should be played - something which is governed by the laws of the game set out by Fifa as the world's governing body.
"In addition to this new guidance, the panel has been tasked to identify key research questions into the long-term effects of head injury or repeated concussion episodes on the brain. The FA will take these research questions to Fifa in due course."

Two special concerts at the Royal Albert Hall will see pupils perform their own response to 10 pieces of classic music.
The Ten Pieces project was announced last year as part of an initiative to inspire primary school children to learn more about classical music.
Each Prom will feature pupils playing music, as well as dance, film and animation.
The schoolchildren's work will run alongside the BBC National Orchestra of Wales, which will play the original 10 pieces of music, which include Mozart, Handel and Holst.
Blue Peter's Barney Harwood and children's TV presenters Dick and Dom will host the concerts on 18 and 19 July, the opening weekend of this year's Proms.
The Saturday concert will be broadcast live on BBC Radio 3, while the Sunday concert will be recorded for future broadcast on BBC Radio 2.
Last June, the BBC announced ten pieces of classical music aimed at inspiring schoolchildren to create their own works.
Since October 2014, some 8,500 primary school pupils have signed up to take part in the scheme, which offers musical workshops from local arts organisations as well as an online film about classical music, which has been seen by more than 120,000 children so far.
The schoolchildren are being invited to submit their "creative responses" to the music to the Ten Pieces website, as either films, audio recordings or images, by the end of March.
The full 2015 BBC Proms season will be announced in April.
