Enhancing Public Availability of Customs Information

general, performance is increasing in per capita income level, which would be expected. But the
difference in performance by income group is by no means constant across pillars. For instance,
the groups are bunched relatively closely together in relation to involvement of the trade
community. By contrast, there is a much larger difference between the low income group and
other groups in relation to the availability of appeal procedures. In general, however, the upper
and lower middle income groups perform relatively well relative to the high income group
across all four pillars, although all are within the best practice frontier set by Singapore. The
performance gap with respect to the low income countries stands out as being more serious.
This finding is consistent with the conclusion of Arvis et al. (2018), based on LPI data, that there
is significant evidence of convergence over time in Customs procedures around the world.

The above analysis uses countries at all income levels. To focus in on developing countries in
particular, it is useful to re-examine the same data byWorld Bank region, excluding high income
countries, so including developing countries only in the sense in which this report is using that
term. Again, Singapore is included as a best practice reference point.
Figure 3presents results. Singapore stands out as being well ahead of the developing regions in
terms of performance in relation to information availability. In the developing regions,
performance varies from pillar to pillar, but is always well inside the best practice frontier. Sub-
Saharan Africa stands out as having performance that is weaker than the other regions across
all areas, although South Asia also performs poorly in relation to advance rulings. Otherwise, the
regions perform, on average, in a relatively similar way that could be characterized as a mid-
range level of compliance with TFA requirements on public availability of information.
Compliance in Sub-Saharan Africa, and to a lesser extent in South Asia, is weaker.
