A system for harmonized commodity description and coding system (HS) code recommendation includes an ontology editor for creating an HS code ontology based on HS codes of export and import items, and a feature vector processor for extracting feature vectors of a product of a company requesting for an HS code of the product by with reference to the description of the product in response to the request. An HS code recommendation unit extracts one or more HS codes appropriate for the product by comparing the extracted feature vectors with feature vectors of the product searched from a feature vector database. The extracted HS codes are provided to the company requesting for an HS code of the product.
