Strange SKU number - can you help?

[red mag]

Hi,
I recently got a stretch with HAP40/SUS410 blade.
On the box it reads: "01SP901" and in a little distance "EU".

From what I found on the net it should red something like: "SP90FPBORE".

Do you know the reason for this different kind of labeling?

Thanks in advance

The EU is the date it was made: May 2017. I do not know about the other code.

Got it. On the other side of the box is the correct code. Thank You.
