Construction method is a primary classification criterion: woven manmade-fiber floor coverings — where the pile or face yarn is interlaced with warp and weft on a loom — classify under this heading, while tufted versions of the same fiber classify under the tufted manmade-fiber heading. Importers should obtain manufacturer production documentation confirming the construction technique, as the two methods can carry different duty rates.

Section 301 tariffs apply to a range of textile floor coverings originating in China, making origin diversification to countries such as India, Turkey, or Vietnam a common strategy. However, importers must verify that goods produced in alternative countries genuinely originate there — substantial transformation rules apply — and should conduct a country-of-origin analysis before shifting sourcing, as transshipment through a third country does not change origin for duty purposes.
