Royal Mail has three international shipping zones:
Europe, which includes Russia and Greenland;
World Zone 1, which encompasses the Americas, Asia, India, and Africa; and
World Zone 2, which is reserved for Australia, New Zealand, Singapore, and several remote islands. International
shipping costs with Royal Mail vary depending on the three types of services. One thing to keep in mind is that Royal Mail doesn't send parcels over 2 kg internationally and redirects customers to Parcelforce Worldwide for such services.
