This would 100% depend on the country you live in, as each one has different - often wildly so - trade laws.
Although I'm almost certain the answer is "no" for most regions, but it does depend on whether you bought the item or not.
If you bought it, you have to pay import fees unless the item is exempt from them - the fact that you're buying the item for review doesn't really matter.
Just resell the item locally after if you don't need it anymore. If you have to pay import duty on the item when buying it, that'll mean the market value will already have the import duty built in, so feel free to try and recoup some of that fee when you sell it.
If the item is being provided for you by the company, you should try and simply get them to pay the duty fees for you. If not? Cost of doing business, you're already getting a free item.
