Jersey's Chamber of Commerce is warning a new waste charge could force businesses to close.
The Liquid Waste Tax, they say, would cost some companies an extra £40,000 overnight.
The Chamber call it "a very real threat" and a "grave concern".
They added it will "especially" hit the tourism and hospitality sectors and it "flies in the face of the Visit Jersey aim to attract 1 million tourists by 2030".
Currently, there is no charge for commercial waste to be disposed of but politicians voted to introduce a fee last year.
Plans are yet to be approved but the Infrastructure Minister yesterday announced he wants to charge £150 per tonne for solid material and £2.27 per cubic metres for liquid waste.
