No Values for Some Countries International USPS Shipping charges

Hi,

We are having a couple issues with International shipping charges. I never noticed this until I found out that Guam didn't return a charge.

1. US Territories are treated as their own countries on the checkout page and don't return a shipping charge from USPS. Does USPS treat these as states rather than countries?

2. These are a list of countries not returning a shipping charge. Is this a result of USPS vs ISO country codes? How do I fix this?

Guam
Antigua
Bonaire
Cen African Republic
Congo
Curaco
Ivory Coast
Marshall Islands
Mauritius
Micronesa
Palau
Ireland
Reunion Islands
Russia
Saba
Saipan
Somalia
South Korea
St Croix
St. Eustatius
St. John
St. Kits & Nevis
St Maarten
St. Thomas
St. Vincent
Syria
Trinadad & Tobago
Turks & Caicos Island
Vatican City
Wallis and Fortuna
Yemen
Zaire



3. What is the best way to set up flat rate shipping based on price and country? If this is accomplished using a shipping rule, would that mean having a shipping rules for US, Canada and every individual US Protectorate?

United States
$0 - $4.99 = $2.42
$5.00 - $9.98 = $3.99
$9.99 - $19.96 = $6.25
$19.97 - $29.94 = $6.25
$29.95 and up = $12.95

US Protectorates - Guam, American Samoa, Marshall Islands, etc
$0 - $4.99 = $2.42
$5.00 - $9.98 = $3.99
$9.99 - $19.96 = $6.25
$19.97 - $29.94 = $6.25
$29.95 and up = $12.95

Canada
$0 - $4.99 = $3.75
$5.00 - $9.98 = $5.83
$9.99 - $19.96 = $6.83
$19.97 - $29.94 = $8.95
$29.95 and up = $10.95

Other Countries
$0 - $4.99 = $8.85
$5.00 - $9.98 = $13.65
$9.99 - $19.96 = $15.65
$19.97 - $29.94 = $17.65
$29.95 and up = $22.95

Appreciate any help to make this easier...

Thanks,

Jack
