The export of products from a jurisdiction is enabled by choosing export codes from a model. The electronic model comprises a branched tree defining a configuration of the export codes and selection criteria for the codes. The branched tree includes a plurality of branches and leaves. Each of the leaves includes an export code for a product, a probability that the export code for the product is accurate, and a description of the product. The tree is traversed to obtain the codes. The tree is trained to improve the quality of the selection process.
