– Using these unitary weights makes it possible to obtain a minimum estimation of the units
managed. This is because in practice it would be expected that equipment unitary weights
of 2020 models would be lower than those of older WEEE technologies.
– Weights reported by the General Directorate of Customs include the main equipment
(EEE) and its electronic accessories. For example, the cell phone and its headphones and
charger. This should be considered to interpret the results for devices that normally have
accessories such as laptops and cell phones. UNU use weights of EEE alone (not including
accessories such as chargers, headphones and the like) and result from field studies in the
region, samplings, reviews of scientific journal articles, experiments and so on.
– It is important to underline that the average unit weights of imports vary by import group
as shown in Figure 36.
