Maine retailers that ship products to Canada could see a sales boost under a new North American free trade deal.
The United States-Mexico-Canada Agreement, the proposed successor to NAFTA, would allow the first $150 (Canadian) of goods bought in the U.S. and shipped to Canada to be duty-free. It also exempts the first $40 from Canadian sales tax.
The current duty-free threshold is only $20 (Canadian), or about $15 (U.S.).
