Finland -> USA, a regular postal service envelope (less than 30mm thick, 1.99kg) is 18.50 EUR (10-15 days). From Finland to USofA couriers are are starting around 25 EUR for 0.99 kg package (UPS, 6-9 days, delivery from a Finland UPS service point to recipient home). And not much more for heavier packets either.

To ship to Vietnam, choose a carrier like USPS, FedEx, or UPS for speed/convenience, or use sea/air freight for larger shipments. You'll need to correctly address the package using the new Vietnamese format (no districts), declare contents accurately on customs forms (like PS Form 2976-A for dutiable items), and be aware that the recipient may pay VAT/duties over a ~$44 value.
