There may be a variety of reasons why Shiprocket may not allow you to ship more than 30 kilograms internationally. Some possible reasons could include:


Shipping restrictions: Different countries have different restrictions on what can be shipped into the country. Some items may be prohibited or restricted, and certain weight limits may be imposed.


Carrier limitations: Different carriers have different weight limits for the packages they can transport. If the package exceeds the weight limit for the chosen carrier, it may not be accepted for shipping.


Cost: Shipping larger packages can be more expensive due to the increased weight and size. Shiprocket may have a weight limit in place to keep costs reasonable for both the seller and the customer.


It is always best to check with Shiprocket or the chosen carrier for specific weight limits and shipping restrictions before attempting to ship a package internationally.
