For wreaths the grading code S74 (Material diameter) will become mandatory from 1 November 2016. This has been a recommended code for several years.
The grading codes for wreaths are as follows from 1 November 2016:
Grading code S74 is being made mandatory partly in response to requests from buyers.
To measure the material diameter, the following rules apply:

- Diameters of decorated wreaths (with foliage, etc.) are taken as the bare diameter plus 5 cm.
