Bamboo fabric is almost always produced through a chemical process that converts bamboo cellulose into viscose (rayon) fiber. CBP and the FTC treat such fabric as a manmade (regenerated cellulose) fiber, not a natural vegetable fiber — meaning it would fall under a manmade-fiber terry heading rather than this one. Importers should verify the production process and fiber designation with the mill before classification.

Textile products sold at retail in the US must comply with the Textile Fiber Products Identification Act, which requires accurate fiber content labeling by generic name and percentage. For non-cotton terry, the label must correctly identify the actual fiber (e.g., 'linen' or 'viscose from bamboo') — mislabeling can trigger FTC enforcement action independent of any customs classification issue.
