Has anyone bought tractor parts, say from the UK into the US and if so did you have to pay any import tax? The US gov has a duty/tariff handbook online for reference, called HTS guide or something like that. It appears engine/tractor parts for internal piston combustion engines are duty free...according to what I can understand, but the company I'm buying from cannot tell me what import taxes I would pay. They basically said once the parts hit the US, customs would contact me for the taxes then. I'm afraid I cannot enter into a purchase without knowing what it will cost me. I thought I'd see if anyone has gone through this.
