Last updated: April 2026 dataBulk carded wool yarn with a wool content of 85% or more by weight — the workhorse input for woolen-system fabrics and blankets — is subdivided in the US schedule by fiber diameter: line 5106100010 captures yarn with fiber diameter greater than 34.40 microns, while 5106100090 covers all other qualifying yarn. Portugal and the United Kingdom lead US supply under this heading, reflecting their long-established woolen spinning industries. The micron threshold is a hard classification boundary, so importers should obtain fiber-diameter test reports from the foreign mill to ensure the correct 10-digit line is declared.
AI-written summary of the official U.S. Census Bureau trade figures on this page — verify before relying on it.
The US schedule splits heading 510610 at 34.40 microns: yarn with fiber diameter above that threshold falls under 5106100010, while finer or unspecified qualifying yarn falls under 5106100090. The distinction can affect duty rates, so importers should request a fiber-diameter certificate from the spinner before filing entry.
Yarn in industrial cone, cheese, or hank form intended for further manufacturing — rather than packaged in small quantities with consumer labeling — generally satisfies the 'not for retail sale' condition. Commercial invoices, packing lists, and mill certificates describing the industrial packaging format are the standard supporting documents.
