Scope and Applicability This PCR governs foreground data packages for synthetic staple fibres that have been carded, combed, drawn, blended, opened, or otherwise prepared for spinning while remaining unspun fibre material. It applies to disclosed synthetic polymer families such as polyester, polyamide, polyolefin, acrylic or modacrylic, and elastomeric-containing staple-fibre preparations when the output is classified within CPC 26210. Synthetic-synthetic blends may be included with their mass fractions declared. Mixed synthetic/natural or synthetic/artificial fibre preparations require an explicit classification determination and must not be assumed to belong to this PCR. The common route is dry mechanical preparation from received synthetic staple fibre through opening, feeding, blending and a declared alignment/preparation operation. Combing and drawing, wet cleaning, application of spinning lubricants or antistatic agents, thermal conditioning, and dust-abatement operations are included only when they occur at the reporting facility. Each polymer family, blend composition, virgin or recovered feedstock route, preparation technology, and optional treatment route must be modelled separately unless foreground evidence demonstrates that aggregation remains representative. Polymer synthesis, primary chemical-fibre manufacture, tow conversion to staple where it occurs before the declared input gate, yarn spinning, twisting, winding, sizing for weaving, weaving, knitting, nonwoven manufacture, dyeing, printing, coating, and textile finishing are outside this PCR. The output is fibre prepared for spinning; it is not yarn and is not woven or other fabric. ## 2.

This PCR uses the UUID only as the required Tiangong database identity. Every foreground data package must override the misleading implication through the required qualifiers and a product description that states “synthetic staple fibre processed for spinning, not woven fabric”. The flow name must never be used to include weaving or any fabric manufacture. Classification scope is supported by `un-cpc-v3-2025`; the process-state distinction is supported by `ec-jrc-txt-bref-2023` and `ifc-textile-ehs-2007`. ## 4.
