We will try our best to help clients avoid extra tax, and only 0.1% of the delivered parcels have ever been taxed, your parcels are almost always guaranteed to pass through Customs with no problems. However, on the off chance that your shipment is withheld by Customs, It's always buyer's responsibilities to clear customs and pay the relevant custom duties.

Advice:
(a). Having more than 5 of the same items in one purchase will also draw the Customs' attention. If necessary, try separating the items into different parcels.
(b). In some countries, parcels that weigh over 10KG will be considered commercial; Customs will block these parcels and ask you to pay duties. Divide package into several small packages and restrict single package weight.
