Abstract: Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, for a user interface for enforcement of shipping rules. In one aspect, a method includes accessing regulation information/data, the regulation information/data being a multi-level hierarchy of nodes arranged in a tree structure, each node specifying one or more keywords, wherein the nodes comprise one or more starting nodes having one or more child nodes and having no parent nodes, one or more intermediate nodes having at least one of a child node and a parent node, and one or more end nodes having at least one parent node and no child nodes. Determining, that a particular keyword from the received one or more keywords matches a keyword of a node in the hierarchy. Determining, a level and a type of the node in the hierarchy, wherein the type of the node specifies whether the node is one of a starting node, an intermediate node, and an end node.

Abstract: Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, for a user interface for facilitating enforcement of shipping rules. In one aspect, a method includes receiving one or more keywords via a first user interface element descriptive of a good to be shipped, determining whether at least a portion of at least one of the one or more keywords matches at least a portion of a corresponding keyword in a keyword list, responsive to determining that at least a portion of the at least one of the one or more keywords matches at least a portion of a corresponding keyword in the keyword list, identifying an action to be taken for the at least one of the one or more keywords, and providing a second user interface element within the user interface, the second user interface element being associated with the action to be taken.
