The Trade classifications serve as a rough guide to the astographic, economic, and social conditions of the system. Generated and updated by the Imperial Interstellar Scout Service, the classifications are used widely by merchants to classify the types and availability of markets.
The term Trade classification is frequently abbreviated as "TC". This in turn is expanded back to Trade code, which is an equally valid term of use. Combined with the Sophont Codes, these form the remarks section of the Sector File Format.
In the published data the trade classification codes and the sophont codes are sorted together in alphabetical order. In some processing systems the codes are divided into the categories for analysis.
Each trade classification has a two letter abbreviation, an identifying name, and a specific description of parts of the system it is classifying. The complete list of valid trade classification combinations.
Trade classifications are divided into eight categories:
- Describes the Planetary Size, Atmosphere, and Hydrographics of the world.
- Classifies the population of the world
- Describes the economics of the world through a combination of planetary environment and population
- Describes the broad climate of the world compared to the Standard environment.
- Additional classification for worlds.
- Adds remarks about the political state of this world
- Additional classification that warrant special attention.
- Sophont codes
- A listing different kinds of populations living in the system. A note of native populations

Sample trade classification sequence
|UWP Typical TC Format Key|
|[Ag Ni Ga / An Tp / Huma3 Varg7 / O:8511]|
|Ag Ga Ni||An Tp||Huma3 Varg7||O:8511||A mainworld may have all or none of the sequences.
|Agricultural, nonindustrial garden world.
||A temperate climate world with an Ancients site.
||30% human & 70% vargr population.
||This world is occupied from world 8511 within the same sector.
||This example does not come from any actual world within Charted Space.
- "O" worlds are worlds that are occupied from a mother world. It is only possible to be occupied by one world at a time under normal conditions.
- "C" worlds have colonies on other worlds. Worlds that start colonies may have any number of colonies. In fact, some high population worlds within Charted Space have five, six, or more colonies.
The Office of the Emperor, the Imperial Bureaucracy, the Imperial Interstellar Scout Service, the Travellers' Aid Society, the Merchant Service, the Educational Institutes, and many other interstellar organizations use this data for governance, interstellar economy, world surveys, and other necessary tasks.
