Here are some old, basic, informmation on packages to any county from the U.S. Old in that I use to mail packages mostly into Europe and a few other countries.
Postage, alone, derpends upon weight plus how fast you want it delivered. Express mail, airmail, prior mail, parcel post, surface, etc. Depending upon your choice it can range from about 5 days to over 30 days, or more.
Your tax charge is set by YOUR government and varies depending upon the item you are receiving. I am using these examples as examples only and are NOT correct. Disney pins, 60%, clothing 40%, wood items 30%, etc. etc.
To get the correct percentage of tax charges I would suggest that you write to your tax office and ask them the percentage. To save you some time you might ask them to quote a couple of items you might order in the future for reference purposes. You might ask if they have a printed list.
Check with who is mailing your package and they will give you the total cost of mailing the package the way and time you wish it sent. Remember that you will have to pay the tax when you receive it and it is not included in the postage costs.
These taxes can, or will vary from country to country.
You can now decide if you want to pay the total cost to have you items sent to you, or not,
