eClass

NHS eclass

NHS eclass is just the first 3 letters of NSV, there has been some divergence from NSV headings, however most categories are still the same as the original top 3 levels of NSV, and there are still around 2,500

e2class is a more flexible hierarchy than NSV, and so e2class for NHS can support the NHS eclass headings linking down through 4th and 5th level NSV heading to the underlying codes.

@UK PLC maintains a complete mapping to eclass versions 1 and 2 for both buyers and suppliers.

German eclass - ecl@ss

Is a 4 level hierarchical category level classification system.  It does not go down to individual product items and comes from a background in the German Energy industry.  It has a similar number of categories to UNSPSC at 32,832 in release 6.2.  However, it has a significant improvement over UNSPSC in that it has standard attributes for categories, and these have been created for over 50% of sub-groups.

NSV and e2class can be completely mapped to ecl@ss, since they have about 20x as much information as ecl@ss.  It is only possible to go back to NSV/e2class at heading level from ecl@ss.
