While the GTRIC does not give a direct measure of the overall magnitude of counterfeiting and piracy in world trade, it establishes relationships that can be useful. Specifically, the GTRIC matrix can be used to approximate international trade in counterfeit and pirated goods.
For each good coming from a given provenance economy, GTRIC assigns a probability of it being counterfeit, relative to the most intensive combination of product and provenance economy. In theory, the absolute number of counterfeit trades for one provenance economy-product can be integrated into the corresponding cell of the GTRIC matrix to yield the total value of world trade in counterfeit and pirated products (see Annex B for more details).
However, determining this total value is currently impossible for two main reasons: first, the clandestine and dynamically changing nature of counterfeit trade makes any measurement exercise extremely difficult and highly imprecise; and second, operational data from customs offices are in most cases strictly confidential.
Nevertheless, the GTRIC matrix can be employed to gauge the “ceiling” value for international trade in counterfeit and pirated goods. As in the OECD/EUIPO (2016) report, this approach is taken by establishing an upper limit of counterfeit trade (in percentages) from the key provenance economies in product categories that are most vulnerable to counterfeiting. These values are called “fixed points”.
The last step in the analysis is to depart from relative intensities of counterfeiting to gauging of absolute values of counterfeit and pirated products in international trade. To do this, at least one probability of containing counterfeit and pirated products in a given product category from at least one provenance economy must be identified. Importantly, this identification must be based on information other than customs seizure data, given the several methodological biases that these data suffer from.
In the 2008 study, this fixed point was determined based on ex ante assumptions that were debated with industry and enforcement representatives. At the time, this was the best possible methodological approach given the poor data quality.
For the analysis presented in the OECD-EUIPO (2016) study, a set of confidential and structured interviews with customs officials were carried out. These interviews resulted in a large number of detailed quantitative and qualitative sets of information on customs operations that in turn allowed this report to determine the upper limit of the absolute number of imported counterfeit and pirated goods. Eventually, the fixed point was set at 27% for HS64 (footwear) from China.
For the present study, the fixed point used in the OECD-EUIPO (2016) study was re‑examined based on a focus group meeting and on interviews with customs officials from several EU member countries. These interviews confirmed that the fixed point picked for the analysis presented in the OECD-EUIPO (2016) study still holds. Consequently, this fixed point was also used in the present analysis.
Of course, such a fixed point does not imply that, on average, 27% of footwear exported from China is counterfeit: it represents the upper level of a potential trade in counterfeits, meaning that within the HS64 category imported from China by some EU members, the share of counterfeits was reaching 27% in some years. This result could then be extrapolated onto the yearly trade flows, which would give a basis to be applied to GTRIC. Consequently, the results presented in this study refer to the upper possible limit of trade in counterfeit and pirated goods.
