Depends upon the item's size, weight and type.
If the shipping cost is affordable, always opt for AliExpress Standard Shipping. It has tracking, it is reliable, and reaches here in average 15-16 days.
(aajkal to Daraz walay bhi 10 din laga rahay hain yahan).
Otherwise ordinary carriers (like Cainiao, take almost 40-60 days to deliver here, many item still don't reach to the buyer.)
