The word 'linen' is used colloquially to describe table textiles regardless of fiber content. A product marketed as 'linen' may be made from cotton, polyester, or a blend. Classification depends on which fiber predominates by weight: if cotton leads, the article belongs in 65845; if synthetic fibers lead, it may fall under a different subheading. Only articles where flax or another non-cotton, non-synthetic fiber predominates belong in 65846.

There are no mandatory federal admissibility standards specific to woven table linen beyond textile labeling requirements. However, buyers in the hospitality sector often impose private-label specifications for colorfastness, shrinkage, and tensile strength. These are contractual rather than regulatory requirements and do not affect customs clearance.
