We usually ship within two to three business days after the full payment. Standard delivery generally occurs within 5 to 7 business days after the shipping date. However, sometimes delivery may take about 7 to 10 business days, depending on the shipping destination, logistics mode, weather conditions, product weight, size, or shipping company distribution structures based on re-planning, such as staff shortages caused by COVID.

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. To benefit from lower shipping costs for orders with multiple items, don't hesitate to contact us at sales@ozrobotics.com. Our shipping rates are listed very clearly on each product page under the SHIPPING tab. Additionally, to see the shipping cost for your country, add the item to the Shopping Cart; you will see the shipping cost based on your Country and Location.

CUSTOMS and TARIFFS: While not all products require a tariff, some products may require a minimal tariff if applicable in your country for orders of $800.00 and above. 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 Partner, or Supplier are not responsible for tariffs. Please check the "Made In" and "Made By" 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. Please click here to see more on Tariffs.
