Duties on Alcohol and personal goods brought into USA from abroad

Given the current worldwide tariff environment, I am wondering if anyone has personal experience with bringing goods into the USA for personal use.

My understanding is that alcohol, for example, is limited to 1 liter per person. You can bring additional alcohol subject to a flat duty plus any Internal Revenue Tax (IRT) that is due. As an example, if you have 5 liters of alcohol, the first one is duty free. The remaining 4 are subject to 3% flat duty plus approx 0.3% IRT. At least that is how I understand it.

I don’t know about other items such as handbags, if they would follow the same rules up to a $4,000 limit?

Up to last week you could walk in with a case of wine for personal use , declare it and they would wave you through since the tax was barely worth collecting. (Done it- can’t walk in with too much because then it’s commercial and needs all sort of rules , but a case is easily looked at as personal ).

As of today ?! No idea , could be looking at a country of origin tax which would be substantial

Ok, I thought items walked in for personal use were not subject to tariff. Is that not correct?

¯_(ツ)_/¯ - who knows how the rule is written and what will be enforced. Or how it will change.
