Applying Section XI Note 7 Criteria to Borderline Linen Goods
Applying Section XI Note 7 requires auditing mill edge finishes, drawn threads, and cutting geometry to prevent high-duty Chapter 63 customs reclassifications.
Edge Finish Classification
Structural Standard
A categorization system defines the boundaries of edge treatment for woven materials. Industrial quality desks use edge finish classification to group fabric rolls by the integrity of their selvedges and finished borders. This method divides the goods into fringed, raw, bound, or hemmed outputs.
Inspection tables at Chinese finishing mills rely on these bins to separate high-value export lots from secondary runs.
Quality Grading
Weft yarns must lock firmly at the borders to prevent unravelling during the high-temperature finishing wash cycle. Manual audits at the physical inspection table verify that the lock stitch holds under lateral force. Technicians apply specialized hand-held mechanical tension gauges to measure the resistance of the locked fringe.
If the calculated density of these stabilizing stitches falls beneath twelve units per centimetre, the finished roll falls into a secondary quality grade. This downgrade reduces the export valuation of the shipment.
Defect Tolerance
Defects such as loose fringes, missed stitches, or excessive thickness can disrupt subsequent cutting processes. A high-density weaving line will reject any batch containing more than one raw edge defect per fifty metres of cloth. Mill buyers check these sheets before authorizing shipment.
This prevents downstream blockages at garment factories.
