Standard delivery generally occurs within 5 to 7 business days after the shipping date. However, the delivery may take about 7 to 10 business days, depending on the shipping destination, logistics, weather conditions, product weight, size, or shipping company distribution structures.

SHIPPING COSTS: For some industrial products, e.g., heavy wheels, CNC machines, etc., the shipping cost is calculated based on the product weight, not quantity.

CUSTOMS and TARIFFS: While not all products require a tariff, some products may require a minimal tariff if applicable in your country. The total amount for your order does not include a customs fee/tariff. A tariff belongs to the buyer when applicable. 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. However, we do not do that because each country charges a different amount, while some do not even charge. Therefore, we can't add any tariff to the product's retail pricing. 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. If you choose not to pay the tariff and parcel returns, there will not be any refund. Please click here to see more on Tariffs.
