The Finnish national LVI-numbers are unique 7-digit identification numbers for the HVAC-products sold on the Finnish market. With these LVI-numbers the HVAC-products are identified in the whole supply chain. Therefore, when product features or usage changes significantly, a new LVI-number is needed.
Features resulting to a LVI-number change are typically modifications in power, measures, colour, design or a material of a certain product.
For instance, when the colour of a washing basin is modified from white to black, while the measures stay the same, a new LVI number is required.
A change in a product code means usually that a new LVI-number is required.
Note that changes in GTIN13 –code, customs code, CE marking, country of origin or package information, do not require changing of LVI-number.
