Shipping costs without logging

-- HikaShop version -- : 5.1.0
-- Joomla version -- : 5.1.3
-- PHP version -- : 8.1.29

Hi
I´m a bit confused with an issue.
When I use the shop as guest, not logged in, there are some products that when they are added to the cart have shipping costs. All the others until you log in and set a shipping address, that cost is 0 as the shop doesn´t know the destiny.

What can I look for in that specific products?. There are so many parameters and I haven´t success finding which one is the difference.
Thank you very much

Hi
It applies the first shipping method. But it only happens in some specific products. I don´t know which parameter depends on the product. The only restriction is of country.
I´m going to delete one of the wrong products and create it again. If that fix the problem it must be a product parameter.
AS I´m not sure of all the products that culd be wrong, I want to locate the reason in order to check all.
Thank you very much

OK
I think i know where it´s the problem. Fowolling your advice i have checked all the shipping zones. The best solution is to delay the shipping costs to the address selection page. I´m searching where i can set that option.

Thank you ver much for your help again.

Finally I changed level access of each shipping zone to registered and then no shipping cost appears in the cart without logging.
Now I will try to set a message "Costs will be calculated duging the checkput" for example.

Thanks again for your patience and help

Working fine.

Thank you very very much
