Last updated: July 2026 dataCotton is the dominant secondary fiber in these blended yarns, where artificial staple fibers such as viscose or modal account for less than 85% by weight — a blend profile common in lightweight apparel fabrics, shirting, and casual wear where cotton's breathability is enhanced by the luster and softness of artificial fibers. India leads US supply, with Indonesia and Costa Rica also among the top sources. The 'mixed mainly with cotton' qualifier requires that cotton outweigh any other non-artificial fiber present, a threshold that must be supported by fiber analysis documentation. The single 10-digit line is 5510300000.

The 'mixed mainly with cotton' qualifier means cotton must be the predominant non-artificial fiber by weight. If the secondary fiber is wool or fine animal hair, the yarn classifies under 551020; if the secondary fiber is another synthetic or artificial fiber, it may fall under 551090. Importers should obtain a full fiber breakdown from the spinner to confirm the correct heading before filing entry.
Costa Rica has a smaller but active textile manufacturing sector with some integrated spinning capacity, and its geographic proximity to the US supports competitive logistics for bulk yarn shipments. Its appearance among top suppliers for this specific blend category likely reflects niche production relationships with US apparel manufacturers rather than broad-based commodity volume.
