Core-Spun Polyester-Cotton Yarn for Shirting from Japan

This is a core-spun yarn with a polyester filament core, surrounded by a sheath of 60% cotton and 30% polyester staple, used for fine shirting. It falls under tariff item 5509.92.00 because, considering the synthetic staple fibres (polyester staple) and cotton, the yarn is mixed mainly with cotton and is not put up for retail sale; the filament core does not change the classification of the staple fibre yarn.
