Check the tax-free information for customs clearance/general customs clearance.
There is no weight limit, but if the cargo value exceeds$200.00, taxes will be incurred during customs clearance.
For general customs clearance, the government sets a fixed freight rate based on weight. When clearing customs, the freight rate determined by weight is added to the declared cargo value. If the sum exceeds $150, taxes will be incurred.
(In other words, please allow for a generous margin, as there may be slight discrepancies depending on the exchange rate on that day.)
