Classification Visualization
UNSD-WTO visualization tool for W/120 to CPC (prototype)
Last updated on 2 December 2022
The UNSD-WTO visualization tool for W/120 to CPC is intended to help negotiators navigate between the WTO Services Sectoral Classification List (MTN.GNS/W/120) and the various versions of the Central Product Classification. This visualization shows the interlinkage of codes of W/120 and CPC in consecutive versions: W/120 – CPC Provisional – CPC Ver. 1.0 – CPC Ver. 1.1 – CPC Ver. 2.0 – CPC Ver. 2.1, in a chronological order (forward direction) or in a reversed order (backward direction). This prototype was jointly developed by UNSD and WTO.
For the correct interpretation of the visualization, please note the following:
- The chart should always be read from left to right, starting from the initial code on the left and then progressively moving to the right.
- In the chart, lines across two adjacent classifications represent correspondences (although possibly partial), whereas lines going across non-adjacent classifications (e.g. from CPC Ver. 1.0 to CPC Ver. 2) represent possible links between the codes, and they should not all be interpreted as actual correspondences. This means for example, that the lines between W/120 and CPC Provisional represents a correspondence. Lines between W/120 and later CPC versions (e.g. from W/120 to CPC Ver. 2.1) represent possible links between the codes, and they should not all be interpreted as actual correspondences. Users are strongly encouraged to check the description of the specific codes.
- Information of the partial correspondences is not displayed in the visualization.
Please select the classification "Version", then select a specific "Code", and select the "Direction"
(forward means to display links from a classification to later versions of CPC, backward means to display links from a classification to previous versions of CPC and to W/120).
Click “Visualize” to show the chart.
In the chart, the columns represent different classifications in sequential order, lines across contiguous versions of the classifications represent correspondences.
Each CPC code has a hyperlink to the detailed description of the code (in a new window). For the W/120 codes, please see MTN.GNS/W/120.
