NHM codes without a valid HS equivalent to be discontinued from May 2027

NHM codes are used to classify goods transported in international rail freight in a standardised way. The abbreviation stands for ‘Nomenclature Harmonisée des Marchandises’, the harmonised goods nomenclature. The change is due to the alignment of the NHM nomenclature with the HS/CN structure (Harmonised System of customs tariff classification). As a result, certain NHM codes will no longer be valid. From the deadline in May 2027, these codes can no longer be used: RCG systems will no longer offer or accept them when transport orders are entered. 

Which codes will be discontinued? 

The decisive factor is whether an NHM code corresponds to a valid HS classification. If there is no such equivalent, the code can no longer be used from the deadline. The change mainly affects six-digit NHM codes ending in ‘00’. However, the ending alone does not indicate whether a code will become invalid. The only determining factor is whether a valid NHM/HS code exists. 

An NHM code ending in ‘00’ will remain valid if it corresponds to a valid HS classification and no further subdivision exists. The required code depends on the goods actually being transported and their technical goods description. 

Changes to systems and master data 

For customers using affected NHM codes, the change requires adjustments to templates, interfaces and master data. These include, for example, templates in MIKE Ordering Transport Order, interfaces and customers’ own systems. 

RCG recommends checking the NHM codes currently in use at an early stage and making any necessary adjustments in good time. This will help to avoid data entry errors and delays when entering transport orders from May 2027.
