APPENDIX I
MC IV “Wide dispersive use”
The term wide dispersive use should be used for a wide range of activities particularly when end
users come into contact with the products. This means a large number of small point sources like
households or line sources like traffic.
Although the HEDSET allows for one entry of the MC only for all stages of the life-cycle, the
approach of MCs is used in EUSES in many cases for several stages of the life-cycle. As can be
seen from Table 1 interpretation is often different.

208
MC Life-cycle stage Interpretation
Ia Production Non-isolated intermediates (Industrial category 3 or 9 & Use category 33)
Ib Production Isolated intermediates stored on-site, or substances other than intermediates
produced in a continuous production process
Ib Formulation Dedicated equipment and (very) little cleaning operations
Ic Production Isolated intermediates stored off-site, or substances other than intermediates
produced in dedicated equipment
Ic Formulation Dedicated equipment and frequent cleaning operations
II Formulation Inclusion into or onto a matrix
II Processing 1) Non-dispersive use (industrial point sources), or processing of intermediates
in multi-purpose equipment
III Production Multi-purpose equipment
III Formulation Multi-purpose equipment
III Processing 1) Non-dispersive use (industrial point sources), or processing of intermediates
in multi-purpose equipment
IV Processing 1) Wide dispersive use (many small point sources or diffuse releases; normally
no emission reduction measures)
1) Processing refers to industrial / professional use
10. Remarks on the industrial categories
This paragraph defines the scope of the Industry Categories (ICs) and presents some short
remarks on the ICs in relation to the A- and B-tables. The definition is based on the examples
specified in the HEDSET for substances classified in the appropriate ICs.
One of the main problems using the A- and B-tables is the fact that it is often difficult to
determine the correct tables to be used, i.e. to determine the correct IC-UC combination
(industrial category-use category). The cause can be divided in two:
1. Correct categorisation is impossible because no suitable use category can be determined on
account of the notification. Furthermore, problems may arise when the application of a
substance takes place in a process that occurs in more than one industrial category.
2. The specification of the industrial category and/or use category by the notifier is wrong, and
determination of the proper combination fails due to the fact that the detailed information of
the notification may be cryptic.
