There's been a long-standing exemption for items brought back on a trip - $800 limit, with specific separate limits for, e.g., alcohol.

Before the recent tariffs even if you were modestly over the limit CBP rarely sought to collect tariffs on the amount over the exemption (I personally have been allowed to bring ~$2500 of goods, with my spouse, over the $1600 joint limit). In part that's because tariffs were generally so low that it wasn't worth their time - my example would have been about $25 in tariff)

Has anyone's experience been different recently now that tariffs have been increased for a number of goods? In particular I'm wondering about (European) wine, but any experiences welcome.
