'Mixed mainly' means the artificial staple fiber (e.g., viscose, modal, lyocell) is the predominant non-polyester component by weight. If cotton or wool exceeds the artificial fiber content in the blend, the yarn would shift to 550953 (cotton) or 550952 (wool/fine animal hair) respectively. Fiber analysis documentation from the mill is the standard evidence used to support the declared classification.
5509513000 covers single-strand polyester/artificial staple blended yarn, while 5509516000 covers the same fiber blend in a plied or cabled construction. The distinction matters because the two lines may carry different duty rates and are tracked separately for trade statistics. Importers should confirm the yarn's construction — single versus plied — with the manufacturer before classification.
