Gimped yarn and strip; chenille yarn; loop wale-yarn

1. Scope and Applicability

This PCR applies to factory-gate production of the specialty textile yarn products classified in CPC 3.0 code 27995: gimped yarn and strip, chenille yarn, and loop wale-yarn. It covers products formed by controlled feeding, wrapping, looping, cutting where applicable, twisting or binding, winding, inspection, and factory packaging of declared yarn or strip components. Natural, regenerated-cellulosic, synthetic, mineral, metallic, and blended component routes are eligible when their exact composition and construction are declared.

The PCR excludes ordinary single, folded, cabled, textured, sewing, tyre-cord, and retail yarns whose classification belongs elsewhere; woven, knitted, tufted, or braided fabrics and articles made from the specialty yarn; fibre and polymer production; use; and end-of-life. Fibre preparation, conventional spinning of input yarns, and dyeing or wet finishing are upstream unless operated at the reporting site and explicitly added as separate processes with complete atomic inventories.

rule_id	Applies to	Rule	source_ids
allocation_avoid	Shared formation, winding, inspection, and packaging operations	First subdivide meters, production orders, machine time, material issues, and waste records so each product construction carries its directly measured burden.	ec-pef-2021
allocation_physical	Residual shared inputs and outputs	When subdivision cannot eliminate a shared flow, use the physical driver that causes it: metered machine energy, machine-hours at documented operating state, processed mass, or package count and mass. Record the driver and all product totals.	ec-pef-2021
allocation_economic_last_resort	Multi-output operation lacking a defensible physical relation	Economic allocation is permitted only when no causal physical relation can be demonstrated; use contemporaneous factory-gate values, disclose the method, and test sensitivity.	ec-pef-2021
