This module provides a hands-on case study on how to perform unit value checks for imported live ducks, geese, turkeys, and guinea fowls weighing more than 185g. The module covers the calculation of value/mass, value/quantity, and mass/quantity ratios, outlier detection, correction of mass and quantity, and manual control for certain criteria.

Module : Unit Value Check Example : Importation HS 010599 : Live ducks, geese, turkeys and guinea fowls weighting >185g 3 sets of Indicators : Value (in €) Mass (Net Mass) Quantity (Supplementary Unit) 3 ratios to test : Value/Mass : Unit Value to be tested Value/Quantity : Other Unit value Calculation Mass/Quantity : Unit Mass test (in this case > 0.185 kg) Outlier Detection : Definition of the range for these 3 Ratios and correction of Mass (with manual post-verification) and Quantity ex : CorrectedQuantity = Value / Ratio(Value/Quantity)
Closeness : (Means-StDev)/Means*100 +/-30% of Min Max Means 10% of value Excluded Product Flow MinUV1 MaxUV1 010599 Import 0.651 2.585 Product Flow MinUV1 AvgUV1 MaxUV1 010599 Import 0.651 1.542 2.585 Product Flow MinUV1 AvgUV1 MaxUV1 Closeness NbItem NbSel 010599 Import 0.651 1.542 2.585 0.65 47 41 Range : Range Calculation Sample 24 Month V a l u e Mass Product Flow 010599 Import

Range : Unit Value Check Automatic Algorithm : 1. Test on Value/Mass Ratio UV Outlier Net Mass Correction 2. Test on Value/Quantity Ratio UV Outlier Quantity Correction 3. Test on Mass/Quantity Ratio Unit Mass Outlier Quantity Correction
Range : Unit Value Check But : Manual Control for Value greater than 500.000 € OR Mass greater than 100.000 Kilo OR Specific list of Product OR Specific list of Trader OR Range with Closeness less than 40% OR Range with Number of Items less than 24 (Less than 1 transaction per month) OR … etc Transaction to be controlled are flagged by program. Another flag have to be checked manually to validate the correction (and/or manual changement of value, mass, quantity)
Range : Technical Considerations 1 . UV Range (Value/Mass) table could be complete by Price Survey (for Raw Material, Farming, …) 2 . UM : Unit Mass must be conform to Product definition (Live ducks, geese … weighting >185g) 3 . A Control Table generated automatically by Eurotrace have to be consulted: - This table contains the number and the percentage of replaced Mass/Value on each Product/Flow within the current processed month. - If for some product, there is too many correction (i.e. more than 80% with more than 5 Values), the current range and the related value have to be controlled, and, if necessary modified
