Why don't we add tariffs to the product's retail price? - If all countries deducted the same tariff amount, we would have added the tariff amount to the product price.

Oz Robotics, manufacturing partners, or Suppliers are not responsible for tariffs. Please check the "Made In:" and "Brand:" labels on the product page to see the product's origin. The total amount for your order does not include any duties, import taxes, customs fees, and GST/VAT. The buyer must pay all import duties.
