Iran has rejected suggestions implying they are willing to discuss their missile programme with the United States.
A spokesperson for Iran's UN Mission said the weapons are non-negotiable.
The statement comes amid Foreign Minister Mohammad Javad Zarif's suggestion that there could be a discussion about the missiles in case sanctions against the country are lifted.
In the interview with NBC News, Mr Zarif had said there was "room for negotiation" once the US removed sanctions.
Alireza Miryousef, the spokesperson for Iran's UN mission, said the country "categorically rejects" the "characterization" of their foreign minister's interview.
The Joint Comprehensive Plan of Action is commonly known as the Iran nuclear deal. It was created and adopted in 2015, with its full implementation in January 2016.
On 8 May 2018, the United States unilaterally withdrew from the nuclear deal.
It is believed that Iran's announcement that the country had surpassed its limits on enriched uranium imposed in the agreement could be a response to Donald Trump's move.
