Footwear with uppers of textile materials, other than sports footwear

1. Scope and Applicability

This PCR governs foreground manufacturing data packages for finished footwear whose upper is made of textile material and that is not sports footwear. It covers open- or closed-toed non-sports footwear when the finished product is classified in CPC 3.0 subclass 29340. It applies to a declared product style, size basis, bill of materials (BOM), manufacturing route, site, and reporting period.

The default foreground boundary starts with purchased finished materials and components received at the footwear manufacturing site and ends with conforming finished footwear and its sales packaging ready for dispatch at the plant gate. On-site component production is included when performed by the reporting facility. Upstream production of purchased textile, polymer, rubber, adhesive, packaging, and other inputs is represented by linked upstream datasets rather than being silently absorbed into the foreground process.

Sports footwear in CPC group 294, footwear with uppers of leather, footwear with both outer soles and uppers of rubber or plastics, protective-metal-toe footwear classified outside CPC 29340, orthopaedic footwear, skating boots, footwear parts sold separately, retail, use, repair, and end-of-life are excluded from the default foreground boundary. A study may model those downstream stages separately, but it must not present the extended system as this gate-to-gate foreground data package.

The process inventory below describes a representative cemented casual shoe with a woven polyester upper, polyester lining, rubber outsole, EVA foam bottom components, and polyurethane adhesive. A conforming data package must replace or supplement representative BOM rows with one atomic flow card for each actual material and component; it must not substitute a plural material family or a route selector for a real exchange.

7. Allocation and Co-product Handling

rule_id	Applies to	Rule	source_ids
allocation_subdivide_first	multi-product or shared foreground operations	Subdivide by process line, product order, style, and reporting period whenever separate measurements exist before applying allocation.	iso-14044-2006; afw-pefcr-v3-1-2025
allocation_process_driver	shared component and manufacturing processes	Apply the PEFCR process driver when subdivision is not possible: unit allocation for sewing and final assembly, and mass allocation for die-cutting, compound forming, insole production, stockfitting, and finishing; document the denominator and all co-produced output.	afw-pefcr-v3-1-2025
allocation_energy	shared site electricity and fuel	Prefer product- or line-specific metering. Otherwise allocate measured energy by a documented causal driver such as machine operating time multiplied by measured or rated load; if only multi-site electricity data exist, use a production-mass-weighted mix and disclose the limitation.	afw-pefcr-v3-1-2025
allocation_recycling_no_credit	manufacturing scrap sent to recovery	Report the scrap mass and treatment route without assigning an avoided-burden credit inside this foreground package; any circular-footprint or substitution treatment belongs to the downstream life-cycle model and must be declared separately.	afw-pefcr-v3-1-2025

9. Validation Rules

rule_id	Applies to	Rule	source_ids
validate_category	reference product identity	Confirm the output has textile-material uppers, is not sports footwear, and is classified in CPC 3.0 subclass 29340; reject a package that relies only on a generic shoe label.	un-cpc-3-0-2025
validate_reference_flow	functional unit and reference flow	Confirm one conforming pair, its reference size, pair count, measured m_pair, Mass UUID, Units of mass UUID, kg reference unit, and the exact Tiangong product-flow UUID are present and mutually consistent.	afw-pefcr-v3-1-2025
validate_atomic_inventory	process inventory	Confirm every selected flow is one material, component, energy carrier, waste, or elementary emission; reject plural collections, combined utilities, route selectors, and an other exchange.	iso-14044-2006
validate_process_coverage	foreground boundary	Confirm upper cutting/preparation/sewing and final lasting/sole attachment/finishing/inspection/packing are represented; confirm bottom-component manufacture is either included or represented by explicit purchased-component inputs.	afw-pefcr-v3-1-2025; oliver-footwear-manufacturing-2021; unido-ilo-footwear-1982
validate_mass_balance	every material-bearing process	Reconcile atomic material inputs with conforming outputs, recoverable transfers, stock change, offcuts, rejects, and other losses; investigate rather than force-close unexplained imbalance.	afw-pefcr-v3-1-2025; iso-14044-2006

validate_no_unsupported_range	inventory amount metadata	Confirm no single case value, repeated lower/upper value, abstract-only value, or unverified estimate is represented as an empirical range; absence of sufficient compatible evidence remains a disclosed range gap.	iso-14044-2006
validate_bilingual_identity	Chinese rendering	Confirm every UUID, process id, row id, controlled token, source id, and normative rule id matches the English source, and the reference flow uses the exact Tiangong Chinese baseName.
