Ramie is explicitly excluded from the jute heading (5310) and classifies under heading 5311 as a vegetable textile fiber not elsewhere specified. Woven ramie fabric, whether plain or blended with other non-excluded fibers, falls under subheading 531100.

The key test is construction: a woven paper yarn fabric has interlaced warp and weft strands of twisted paper strip, giving it a textile-like structure that classifies under 5311. A nonwoven paper sheet or mat formed by bonding or felting paper fibers would fall outside Chapter 53 entirely, typically in the paper and paperboard chapters. Weave structure documentation from the manufacturer is the most reliable evidence.
