Classification overview

Understanding HTS Chapter 50

HTS Chapter 50 covers silk. Within this area of textile fibers, fabrics, apparel and made-up articles, the product name alone is rarely enough to select a heading. The essential facts include fiber composition, yarn or fabric construction, weight, finishing, garment type, intended wearer and whether the article is knitted, woven, coated or otherwise made up. 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.

Before selecting a heading

Classification factors to review

Fiber composition

Determine the percentage by weight of each fiber and apply the textile mixture rules where required.

Construction and finishing

Yarn type, weave or knit, coating, pile, weight and other construction details can change classification.

Article type and wearer

For finished goods, identify the garment or article, intended wearer, dimensions and method of assembly.
