Linen Non Preferential Origin Rules under Harmonized System Tariff Shift
Linen non preferential origin follows exact HS tariff shifts where spinning yarn confers 5306 origin and weaving cloth confers 5309 origin under customs law.
Greige Cloth
Unfinished Textile
Woven fabric directly removed from the loom prior to any wet processing, bleaching or dyeing represents the baseline raw production output. Loom-state greige cloth contains natural bast pectins, residual sizing agents, natural plant waxes and mechanical loom oils that must be removed during subsequent finishing stages. Standard commercial piece goods exhibit higher structural stiffness, darker coloration and elevated dimension instability relative to finished fabric specifications.
Export transactions frequently trade unfinished material on the basis of pick density, yarn count verification and structural flaw point counts recorded immediately after off-loom inspection.
Off-Loom Inspection
Physical grading takes place on automated inspection tables equipped with top and bottom illumination sources. Quality examiners record warp breaks, filling knots, reed marks and oil stains across every piece of greige cloth to compute overall quality point values. Off-loom dimensions vary from nominal finished specifications because yarn crimp and internal tension remain unset by thermal or aqueous treatments.
Sizing starch applied during warp preparation increases fabric stiffness and protects brittle bast filaments from mechanical chafing during weaving. Mill testing laboratories pull strip samples from roll ends to verify warp and weft yarn counts, fabric weight per square meter and moisture content under standardized atmospheric conditions.
Export Logistics
International commercial contracts specify strict dimensional tolerances, minimum tensile strength limits and maximum allowable point counts for unprocessed fabric rolls. Shipping documents categorize greige cloth under specific customs commodity codes that distinguish raw unbleached weaves from bleached or dyed piece goods. Packing lists record net weight, gross weight, roll width and verified piece lengths alongside laboratory test summaries.
Storage environments must maintain controlled humidity levels to prevent fungal growth on natural starches and bast pectins present in the unfinished yarns. Converting facilities rely on detailed greige inspection reports to calibrate subsequent desizing, scouring, bleaching and tentering operations. Compliance with technical acceptance criteria determines whether unfinished linen lots advance directly to export shipment or undergo corrective re-inspection.
Scope Certificates against Transaction Certificates in a Linen Order
Scope certificates approve mill processing capability while transaction certificates validate specific physical shipment mass; buyers must hold final payment until verified transaction paperwork arrives.
