Carpet backing typically uses finer, more uniform single jute yarn in the range of 6–10 lbs/spindle (approximately 200–350 meters per 100 grams), while burlap sacking uses coarser counts in the 3–6 lbs/spindle range. Although the HTS does not subdivide by count, buyers should specify count and twist direction on purchase orders and commercial invoices to ensure the correct product is shipped and to facilitate any end-use verification.

Imports of single jute yarn originating from China may be subject to Section 301 tariffs. Shipments from Bangladesh and India — the dominant suppliers — are not currently subject to Section 301 measures, though importers should confirm current USTR guidance and verify that country-of-origin markings accurately reflect where the yarn was spun, not merely transshipped.
