I understand that by default, Zone Rates are set using Country ISO Codes.

However, for my case here, I would need to have different rates for different Zones within my country, and yet maintain another rates for shipment to other countries.

I have tried to crack my head and look through the Zen Cart Support Forum for solution in setting up the shipping zones, but yet to no avail.

My situation is as follows:
1. I want to have free shipping for Order to be delivered to the Country: Malaysia, Zone: Federal Territory KL, Zone Code: FTKL
2. Shipping to other zones within Malaysia to be varies depending on the zones, e.g Zone Code: MEL,KCH would have one shipping charges depending on weight, where as Zone Code: PEN, SBH would have another shipping charges depending on weight.
3. I also need to have another shipping rate to other countries, e.g. Country: SG & BN sharing the same weight related rate, Counter: US, CA share another weight-shipping rate.

How could I do this?

Appreciate your prompt response...

Cheers,
