Iran presented its proposal in mid-September after an interim ceasefire collapsed.
Tehran later acknowledged receiving a US response but Iran's security chief said last week negotiations had stalled because Washington failed to address all seven conditions for reopening the strait.
"Our situation is clear and based on the seven-days proposal presented to the US," Araqchi told state media on Sunday.
"They shared comments which we are reviewing, but our proposal is still on the table and if there is any honesty on the US part, which there isn't, the way to reopening the Strait of Hormuz is obvious."
Iran's conditions include, among other demands, the lifting of the US blockade on its ports, the lifting of US sanctions on its oil exports as well as ending hostilities on all regional fronts.
If Washington accepts Tehran's conditions, the strait could reopen within six days, with talks resuming the following day, Araqchi said.
A central point of disagreement has been Washington's insistence on addressing Iran's nuclear program from the outset.
US Vice President JD Vance said earlier this month that Iran must make a "meaningful" reduction in its uranium enrichment capacity to satisfy US demands and end the eight-month war.
Meanwhile, Iran's Revolutionary Guards navy says two oil tankers have caught fire after hitting naval mines while crossing the Strait of Hormuz.
The Iranian news agency IRNA reported the claims but there has been no independent confirmation.
IRNA reported that the vessels had switched off their positioning and radar systems and attempted to use an unauthorised route through the strategic waterway.
The Strait of Hormuz, which is only 35 to 40km wide at its narrowest point, has become the central point of conflict between Iran and the US.
Disruptions to shipping in the waterway due to the war have boosted global energy prices and inflation.
Maritime officials said on Wednesday that a container ship and a dry bulk carrier sank near the strait after being hit by projectiles in separate incidents.
Attacks around the waterway have surged over the past two weeks, with Iran saying it is stepping up strikes in response to the US blockade of its ports and tougher sanctions imposed last month.
