4.14. Flows: Imports and exports
All goods and materials that are imported into and exported out of the territory. If there are any national or physical boundaries around your territory then this may be easier to obtain than e.g. a city on the mainland. Look for transport or freight statistics, and try to find what the most detailed level of available information is. You may need to consult an industry expert.
