Import customs duties

Hi everyone

So I’m based in UK. I sourced some products from Portugal seemed like a good deal taking into account shipping cost etc, however I didn’t realise I was going to be hit with duty custom tax once arrived in the UK which cut deep into profit. How do experienced sellers who source from abroad mitigate these costs.

Apparently if we spend under £135 per order we won’t have to pay Duty custom costs but that would mean placing multiple orders.

Any tips?

Are these products manufactured outside of EU? Duty from EU only applies when manufacturing takes place outside of EU, if manufactured in EU there is no duty only import vat which is reclaimable or you can delay payment of import vat

I make multiple purchases and each purchase max 135 and never had any issues
