Recipients in Ukraine will have to pay value added tax on parcels from abroad if the total value of the goods in the parcel exceeds 100 euros. If this limit is exceeded, a payment will be charged: 20% VAT and 10% duty. For example, you received a parcel worth 140 euros from abroad. In this case, the customs duty in the amount of (140-100) * 0.1 = 4 euros will be charged. Additionally, VAT will be calculated in the amount of (140-100) * 0.2 = 8 euros.
In Georgia, a limit on free import of parcels is fixed at 300 lari (around 180 USD) per package from one sender. Packages with declared value over this limit are charged 18% VAT for the excessive value.
So, if you have received a package from eBay worth $1,500, and a package worth $150 from Amazon the same day, you will have to pay (1500-180) * 0.18 = 238 USD customs duties. You will not have to pay taxes for the package from Amazon in this case.
