  The Trade Classifications 
   
   The key to trade is the broad array of trade classifications which distill the details of the 
  Universal World Profile into easily understood two-letter codes. Understanding the trade 
  classifications gives insight into the details of worlds. 
   
   The Trade Classifications are two-letter codes (with format: Capital-lower) which identify an important or unusual detail of the 
  world. For example, Ba is the trade classification for Barren: a world with no population. 
   
  SEVEN TYPES OF TC 
   Trade Classifications fall into seven 
  distinct categories: Planetary, 
  Population, Economic, Climate, 
  Secondary, Political, and Special. 
   
  As De He Fl Ic Oc Ga Va Wa 
   Planetary trade classifications are 
  based on the UWP elements SAH and 
  generally relate to physical aspects of 
  the world. 
   
  Di Ba Lo Ni Ph Hi 
   Population trade classifications are 
  based on the UWP Population and 
  provide an insight into the current local 
  population. 
   
  Pa Ag Na Pi In Po Pr Ri 
   Economic trade classifications are 
  based on the UWP elements AHP and 
  generally relate to economic aspects of 
  the world. 
   
  Fr Tr Tu Tz 
   Climate trade classifications are 
  based on the UWP elements SAH and 
  take into account the world’s relation to 
  the Habitable Zone of the system. 
   
  Fa Mi 
   Secondary trade classifications are 
  based on the UWP elements SAH and 
  take into account the world’s relation to 
  the Habitable Zone of the system. 
   
  Cp Cs Cx Cy Pe Re 
   Political trade classifications detail 
  aspects of interstellar government. 
   
  Fo Pz Da An Ab 
   Special trade classifications detail 
  unusual world details. 
  USING TRADE CLASSIFICATIONS 
   Trade Classifications have several 
  uses: 
   Trade. Some (but not all) Trade 
  Classifications are used to evaluate the 
  purchase cost and the selling price of 
  trade goods. 
   Homeworld and Birthworld Skills. 
  The trade classification for a world 
  determine the skills a character 
  receives during character generation 
  because of his birthworld or homeworld. 
   Land Grant Income. The trade 
  classifications for a world cumulatively 
  determine the income which a Land 
  Grant produces for its holder. 
   
  HOW MANY TCs FOR A WORLD? 
   When evaluating a world, generate 
  all possible trade classifications. 
   Planetary, Population, and 
  Economic Trade Classifications are 
  dictated by the UWP elements; there is 
  no random or discretionary choice 
  involved. 
   Climate and Secondary Trade 
  Classifications are dependent on the 
  orbit of the world. They are imposed 
  only if the entire star system is 
  generated. 
   Political and Special Trade 
  Classifications are discretionary. They 
  are imposed by the referee based on 
  his discretion or the situation. 
   
   In practice, most worlds have 
  between one and three Trade 
  Classifications. A world may have as 
  many as five or six or more TCs. It is 
  possible for a world to have no Trade 
  Classifications.

  Ab Ag An As Ba Cp Cs Cx Cy Da De Di Fa Fl Fo Fr Ga He Hi Ic In Lo 
   
  Ab Data Repository 
   The world has a centralized 
  collection point for information and 
  data. Governments, educational 
  institutions, entertainment companies, 
  corporations, and other organizations 
  for parsecs in every direction deposit 
  records of their transactions and output 
  in this collection point. 
   The TC use refers to AAB, the 
  Imperial designation for data 
  repositories. 
   
  Ag Agricultural 
   The world has the proper climate and 
  conditions which promote extensive 
  farming and ranching. It is a producer 
  of relatively inexpensive foodstuffs. It 
  also is a source of unusual, exotic, or 
  strange delicacies. 
   
  An Ancient Site 
   The world (or conceivably the star 
  system) includes one or more locations 
  identified as the ruins of the long-dead 
  race called the Ancients. Ancient Sites 
  are exploited for the Artifact remains of 
  this long dead technological civilization. 
   
  As Asteroid Belt 
   The world is an asteroid belt which is 
  the primary world or mainworld in the 
  system. It is a producer of raw 
  materials and semi-finished goods, 
  especially ores, metals, and minerals. 
   
  Ba Barren World 
   The world has no population, 
  government, or law level. It has never 
  been developed; it has no local 
  infrastructure beyond the starport (if 
  that).  
   A Barren world UWP has a zero 
  Tech Level. 
   
  Cp Subsector Capital 
   The world is the political center of a 
  group of tens or dozens of star systems 
  (typically a subsector). 
   
  Cs Sector Capital 
   The world is the political center of a 
  group of hundreds of star systems 
  (typically a sector). 
  Cx Imperial Capital  
   The world is the overall political 
  center of an interstellar government 
  controlling thousands of star systems. 
   
  Cy Colony 
   The world is a colony of another 
  world (or of an organization).  
   The inhabitants of this world are 
  called Colonists. 
   
  Da Dangerous 
   Some aspect of the world 
  (conditions, customs, laws, life forms, 
  climate, economics, or other) is not well 
  understood or easily understood by 
  typical visitors, and it presents a 
  danger. The world is an Amber Zone. 
   
  De Desert World 
   The world has no open or standing 
  water. This lack of water significantly 
  reduces the level of agricultural 
  development. 
   
  Di Die-Back 
   The world was once extensively 
  settled and developed, but at some 
  time in the last thousand years its 
  inhabiting sophonts died out leaving 
  behind the remnants of their civilization 
   A Die-Back world UWP has a non-
  zero Tech Level. 
   
  Fa Farming 
   The world has the proper climate and 
  conditions which promote extensive 
  farming and ranching. In addition, it is 
  not a Mainworld and is in the Habitable 
  Zone.  
   Farming is a rare substitute term for 
  Agricultural. 
   
  Fl Fluid Oceans 
   The world's oceans are not 
  composed of water. Non-water oceans 
  may be valuable sources of raw 
  materials for industry. 
   
  Fo Forbidden 
   Some aspect of the world 
  (conditions, customs, laws, life forms, 
  climate, economics, or other) presents 
  an active threat to the health and well-
  being of individuals. The world is a Red 
  Zone. 
  Fr Frozen 
    The world lies substantially beyond 
  the Habitable Zone of the system 
  (HZ+2 or greater) and environmental 
  temperatures are well below the 
  freezing point of many gases. 
   
  Ga Garden World 
   The world is hospitable to most 
  sophonts. Its size, atmosphere, and 
  hydrographic make it an extremely 
  attractive world. A Garden World has a 
  safe environment which does not 
  require protective equipment for 
  humans and sophonts which share the 
  human environment. 
   
  He Hellworld 
   The world is inhospitable to most 
  sophonts. Its size, atmosphere, and 
  hydrographic make it an extremely 
  unattractive world. 
   
  Hi High Population 
   The world's population is one billion 
  or more (Pop = 9 or A). High population 
  worlds, because of the economy of 
  scale for production, produce quality 
  inexpensive trade goods. 
   
  Ic Ice-Capped 
   The world’s water is locked in ice-
  caps.  
   
  In Industrial 
   The world has a strong 
  manufacturing infrastructure and is a 
  producer of many types of goods. 
   
  Lk Locked 
   The world is a satellite (in orbits Ay 
  through Em) which is locked to the 
  planet it orbits. A Locked satellite does 
  not have a Twilight Zone; its day length 
  equals the time it takes to orbit its 
  planet. 
   
  Lo Low Population 
   The world has a non-zero-population 
  less than 10,000.  Low Population 
  fluctuates wildly and may change 
  significantly on a yearly (or less) basis. 
   Locals are Transients: merchants, 
  corporate employees, military, security, 
  or research personnel.

  Mi Na Ni Oc Pa Pe Ph Pi Po Pr Pz Re Ri Tr Tu Tz Va Wa 
   
  Mi Mining 
   The world is the site of extensive 
  mining and mineral resource 
  exploitation. It is not a Mainworld and is 
  located in a star system with an 
  Industrial Mainworld. 
   
  Na Non-Agricultural 
   The world is unable to produce 
  enough food agriculturally to feed its 
  population; synthetic food production 
  generally provides basic food needs. 
   
  Ni Non-Industrial 
   The world has a non-zero population, 
  but it is in the relatively low range of 
  more than 10,000 and less than one 
  million.  
   Non-Industrial population can 
  fluctuate, although not as wildly as on 
  Low Population worlds. Generally the 
  Non-Industrial trade classification 
  remains constant and reflects the 
  expected level of population. 
   The inhabitants of a Non-Industrial 
  world are Settlers: individuals who 
  maintain a permanent settlement which 
  does not yet meet the criteria of 
  Colony. 
   
  Oc Ocean World 
   The world surface is covered with 
  very deep seas. There is no (= less 
  than 1%) land above the ocean 
  surface. 
   
  Pa Pre-Agricultural 
   The world is a candidate for the 
  Agricultural trade classification; its 
  population is just outside the 
  requirement for Agricultural. 
  Pe Penal Colony 
   The world is a dumping ground for 
  individuals who do not (cannot / will not) 
  conform to acceptable standards of 
  behavior. 
   
  Ph Pre-High 
   The world is a candidate for elevation 
  to the High Population trade 
  classification; its population level is just 
  below the requirements for High. 
   
  Pi Pre-Industrial 
   The world is a candidate for the 
  Industrial trade classification; its 
  population is just below the 
  requirements for Industrial. 
   
  Po Poor 
   The world has poor grade living 
  conditions: a scarcity of water and a 
  relatively sparse atmosphere. 
   
  Pr Pre-Rich 
   The world is a candidate for the Rich 
  trade classification; its population is just 
  outside the requirements for Rich. 
   
  Pu Puzzle 
   Some aspect of the world 
  (conditions, customs, laws, life forms, 
  climate, economics, or other) is not well 
  understood or easily understood by 
  typical visitors. The world is an Amber 
  Zone. 
   
  Re Reserve 
   The world has been set aside by the 
  highest levels of government to 
  preserve some aspect of its indigenous 
  life forms, to delay development of its 
  resources, to frustrate investigation of 
  some aspect of the world, or to prevent 
  exploitation of the world by outside 
  organizations. 
  Ri Rich 
   The world has an untainted 
  atmosphere which is comfortable and 
  attractive for most sophonts, and has a 
  population suitable as a workforce.  
   
  Sa Satellite 
   The world is the satellite of a planet 
  (or gas giant) in the system. 
   
  Tr Tropic 
   The world is relatively warmer than 
  normal (although it is considered 
  habitable). Its orbit is at the inner 
  (warmer) edge of the Habitable Zone. 
  The world has a Hot climate (at the 
  upper limits of human temperature 
  endurance). 
   
  Tu Tundra 
   The world is relatively colder than 
  normal (although it is considered 
  habitable). Its orbit is at the outer 
  (colder) edge of the Habitable Zone. 
  The world has a Cold climate (at the 
  lower limits of human temperature 
  endurance). 
   
  Tw Twilight Zone 
   The world is tidally locked with a 
  Temperate band at the Twilight Zone, 
  plus a Hot region (hemisphere) facing 
  the Primary and a Cold region 
  (hemisphere) away from the Primary. 
   
  Va Vacuum World 
   The world has no atmosphere. 
   
  Wa Water World 
   The world surface is covered with 
  water; there is very little land ( = less 
  than 10%) above the water surface. 
   
  Terminology 
   Asteroid Belt. A series of small fragments orbiting a star and which is considered a mainworld. 
   Belt. An asteroid belt.or a planetoid belt.  
   Habitable Zone. The orbit (or orbits) around a star which allow produce local world temperatures and conditions conducive 
  to human (or similar sophont) habitation. 
   Mainworld. The principal or primary or most important world in a star system. The Mainworld may be a planet or a satellite 
  or an asteroid belt.
