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.
