The current laws on fireworks in Northern Ireland have led to a rise in illegal sales, the Northern Ireland Firework Association has said.
The organisation which represents companies involved in the legitimate sale of fireworks wants the legislation brought in in 2002 to be changed.
It says the public are put off spending £30 to buy a licence to use fireworks.
Chairman Paul Kelly says bringing the laws into line with the rest of the UK would help curb the illegal trade.
"What we have argued for is a window of opportunity for legal outlets to sell fireworks," Mr Kelly said. "Where you have a two-week selling period where a licence is not required."
"That would help take away the illegal industry," he said.
"Instead the fireworks are being sold out of houses, out of cars, car boot sales and markets."
A ban on fireworks in Northern Ireland was lifted in 1996 following the paramilitary ceasefires.
However, new restrictions on the use of garden fireworks were brought in May 2002.
