Understanding HTS Chapter 83
HTS Chapter 83 covers Miscellaneous articles of base metal. Within this area of base metals and articles of base metal, the product name alone is rarely enough to select a heading. Classification commonly requires alloy composition, production stage, cross-section and dimensions, coating or other working and the specific function of any fabricated article. Start with a precise commercial description and supporting technical details, then compare the heading wording and relevant section and chapter notes. Also review neighboring chapters when the product has been further processed, combined with other materials or made into a more specific finished article.
Classification factors to review
Metal and alloy composition
Use mill certificates or specifications to identify the base metal, alloying elements and relevant metallurgical thresholds.
Form and dimensions
Ingots, flat-rolled products, bars, wire, tubes, castings and finished articles follow different headings.
Working and article function
Coating, machining, assembly and a specific end function may move a product from raw metal to an article provision.
