Classification follows the fiber that predominates by weight. If silk exceeds all other fibers by weight, the article falls under 621410 (silk or silk waste); if wool or fine animal hair predominates, it falls under 621420. When no single fiber predominates, the General Rules of Interpretation and the relevant chapter notes guide the determination, and a binding ruling from CBP is the safest path for blended articles.

No. Heading 6214 is explicitly limited to articles that are not knitted or crocheted. Knitted scarves, mufflers, and similar articles are classified in a different heading within Chapter 61 or 62 depending on construction, so confirming the fabric-making process is the essential first step before applying this heading.
