Editing Trade classification

[[File: Wiki Navy.png|right]]
The [[Trade Classification]]s or TC's of a [[world]] are a rough socio-economic approximation of a world's sociographic interest to an interstellar [[Traveller Gene|Traveller]].  
* Within each [[UWP]] is a remarks section, used to record various information that might be of interest. Its main use, however, is to record [[Trade classification]] codes for the use of merchants and other traders. 
* Not all world descriptions have trade classifications and/or remarks, some have many of each. 
* The trade classification data is only as good as the source. Prospective merchants should be aware that trade classification data may change or be incorrect.

== Description ([[Specifications]]) ==
[[Trade Classification]]s are used in determining the purchase/sale price of goods. 
* The area in the [[UWP]] for the trade classifications (which are usually abbreviated to two letters) is also used for additional remarks. 
 
=== Sample Trade Code (TC) Sequence/s ===
TC Sequences are a newer astrographic convention and have not been fully regularized by the [[IISS]] yet.

| A [[mainworld]] may have all or none of the sequences.
* None is represented by a dash "-".

| Agricultural, nonindustrial [[garden world]].
* Seq-1 represents primary or common trade codes: economic, planetary, population, etc.
| A temperate [[climate]] world with an [[ancients]] site.
* Seq-2 represents uncommon tags like climate, zones, politics, or other special features.
| 30% [[human]] & 70% [[vargr]] population.
* Seq-3 represents sophont demographics. The default is HumaW or 100% human.
* Insignificant percentages of other [[sophont]]s.
* Should equal 100%.
| This world is occupied from world 8511 within the same [[sector]].
* Seq-4 represents political relationships, usually of subjugation.
* Every "C" has one or more "O" counterparts.
* A world with coordinates of 8511 is ''impossible.'' It's just an example.
| This example does not come from any actual world within [[Charted Space]].
* It is possible for a world to have many colonies.
|-
|}
* "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.

=== Trade Classification Codes ===
Trade classifications are divided into seven categories:
# Economic (primary code)
# Planetary (primary code)
# Population (primary code)
# Climate (secondary code)
# Political (secondary code) 
# Secondary (secondary code) 
# Special (secondary code)

== History & Background ([[Dossier]]) ==
The [[Office of the Emperor]], the [[Imperial Bureaucracy]], the [[Imperial Interstellar Scout Service]], the [[Travellers' Aid Society]], the [[Merchant Service]], the [[Educational Institute]]s, and many other interstellar [[organization]]s use this data for [[governance]], [[interstellar economy]], world surveys, and other necessary tasks.

Such data drives [[Charted Space]]. The TC System is a time-honored practice of the [[IISS]].
