Amazon USA marketplace – Tax question

I am a new Amazon seller.

I have worked with and developed 2 unique designs, submitted to manufacturers in China on Alibaba. I am now ready to make my first mass production purchase and ship it to Amazon warehouse USA.

My question is – on Alibaba, it adds VAT. However, I thought I didn’t have to pay resale tax?

I am a newly formed LLC Business – I thought vat does not apply. Any advice? What am I missing?
