1. Scope and Applicability
This PCR governs foreground manufacturing data packages for finished footwear whose outer sole and upper are both made of rubber or plastics and that is neither waterproof footwear nor sports footwear. It covers open- or closed-toed non-sports footwear within CPC 3.0 subclass 29320, including separately formed synthetic uppers with moulded or cemented soles and one-piece injection-moulded casual footwear. Each data package shall declare the product style, reference size, bill of materials (BOM), material formulation, manufacturing route, site, geography, and reporting period.
The default foreground boundary begins with purchased polymer or rubber compounds, sheets, finished components, chemicals, energy, water, and packaging received at the manufacturing site. It includes every on-site component-forming step, upper cutting or welding, sole or complete-footwear moulding, curing where used, assembly, finishing, inspection, scrap handling, and sales packaging, and ends with conforming finished footwear ready for dispatch at the factory gate. Upstream production of purchased inputs and off-site waste treatment are represented by linked datasets.
Waterproof footwear, sports footwear, footwear with leather or textile uppers, protective-metal-toe footwear classified elsewhere, orthopaedic footwear, skating boots, and separately sold footwear parts are excluded. Distribution, retail, use, repair, and end-of-life are outside the default foreground boundary. Waterproof performance is not inferred from rubber or plastic construction; any product marketed or tested as waterproof belongs outside this PCR.
The representative route is a closed-toed casual shoe with a PVC-coated, textile-backed plastic upper, an EVA midsole, and a moulded synthetic-rubber outer sole assembled with polyurethane adhesive. The process inventory also includes a conditional one-piece PVC injection-moulding route. A conforming data package shall replace non-applicable representative cards with not_applicable and shall add a separate atomic card for every actual material, chemical, utility, waste, and elementary emission.

| How much | One pair of footwear defined by the product BOM and declared reference size |
| How well | Conforming and in good condition for the declared casual, town, school, infant, indoor, or equivalent non-sports use, with declared construction and quality test results |

|---|---|
| Reference amount | 1 Item(s), representing one conforming matched pair |
| Reference product flow | Footwear with outer soles and uppers of rubber or plastics, excluding waterproof and sports footwear |

When constructing a foreground data package, the items listed in Required qualifiers must be declared in dataset metadata, process notes, reference flow comment, product description, or an equivalent data package field. Missing required qualifiers make the reference flow definition incomplete for that data package.
4. Measurement and Unit Rules
| rule_id | Applies to | Required property | Required unit | Rule |
|---|---|---|---|---|
reference_pair_count | conforming finished footwear | Number of items 01846770-4cfe-4a25-8ad9-919d8d378345 | Item(s) | Count one matched left-and-right pair as one item after final inspection; record single shoes only after matching the left and right shoes into a pair. |
reference_pair_mass | conforming finished pair | Mass | kg | Weigh the complete pair after conditioning, exclude detachable sales packaging, and retain reference size, sample count, arithmetic mean, and scale resolution as m_pair. |
pair_mass_conversion | pair-to-mass reporting | Mass | kg/pair | Divide each per-pair exchange by m_pair for per-kg reporting; preserve the original pair inventory and m_pair so conversion is reversible. |
component_mass_basis | compounds, sheets, components, product, and solid waste | Mass | kg | Record gross input, conforming incorporated mass, recoverable regrind or offcut, reject, and disposed mass by specific material and fate; do not hide losses inside product net mass. |
energy_unit_preservation | electricity and fuel inputs | Energy or net calorific value | kWh for electricity; MJ for fuel | Preserve metered units and conversion factors. Electricity, purchased heat, steam, and each fuel are separate exchanges. |
water_unit_preservation | process and cooling water | Volume | m3 | Record supplied water and discharged water separately by source and treatment route; document any recirculated volume without counting it again as a boundary input. |
5. System Boundary

| product_classification_scope | CPC 3.0 subclass 29320 only |
| recursive_input_rule | If partially finished or finished CPC 29320 footwear enters the system, record it as one explicit product input with a linked upstream dataset; do not recreate the same category recursively inside this foreground boundary. |
| upstream_dataset_requirement | Each purchased material, component, chemical, utility, packaging item, and off-site waste-treatment service requires a geographically and technologically representative upstream dataset or a disclosed data gap. |
| disclosure | Declare on-site and purchased component steps, contract manufacturing, BOM and reference size, rubber and plastic formulations, recycled-content and regrind handling, process and assembly losses, energy and water allocation, VOC and particulate controls, reject fate, packaging inclusion, and every excluded process. |
