Importers of Narrow Fabrics of Warp Without Weft Assembled by Adhesive (Bolducs) paid $31K in duties in April 2026 — an effective duty rate of 14% on $216K in dutiable value, based on actual customs collections rather than the published tariff schedule. Narrow Fabrics of Warp Without Weft Assembled by Adhesive (Bolducs) imports of $239K in April 2026 ran 43% above the year-to-date monthly average of $167K.
Last updated: April 2026 dataBolducs are a structurally unique narrow fabric: parallel warp yarns held together by an adhesive rather than interlaced with a weft, producing a flat, ribbon-like strip used primarily in packaging, gift wrapping, and floral decoration. The adhesive-assembly method — not weaving, knitting, or braiding — is the defining production characteristic that places bolducs in their own classification. Importers should be prepared to provide technical documentation confirming the absence of weft yarns and the adhesive bonding method, as CBP may otherwise classify the product as a woven or nonwoven fabric. These goods are typically low-bulk, high-volume items sourced from Asian manufacturing centers.
AI-written summary of the official U.S. Census Bureau trade figures on this page — verify before relying on it.
A mill certificate or technical data sheet explicitly stating that the product consists of warp yarns only, assembled by adhesive without any weft insertion, is the most effective supporting document. Cross-sectional photographs or microscopy images showing the absence of weft yarns can further substantiate the classification if CBP issues a query.
No — bolducs are distinguished from nonwovens by the presence of discrete, parallel warp yarns as the structural element. Nonwovens are formed from fibers bonded without a yarn structure. Even if the adhesive is prominent, the yarn-based construction keeps bolducs in the narrow-fabric classification rather than the nonwoven heading.
