- `destination` (string, required): Destination country ISO2: US, GB, DE, FR, JP, KR, CN, AU, CA, SG, any EU member

- `fxRate` (number): Units of destination currency per 1 unit of currency (skip live FX)
- `goodsValue` (number, required): Price of the goods
- `insurance` (number)

- `vatRate` (number): Override VAT/GST rate (e.g. Canadian HST 0.13)
