1. Scope and Applicability
This PCR covers factory-gate production of clothing accessories whose essential character is supplied by leather or composition leather, including belts, bandoliers worn as clothing accessories, suspenders or braces, leather ties, wrist straps, protective clothing sleeves, and non-sports gloves, mittens, or mitts. It applies to pattern preparation, material selection, cutting or clicking, splitting or skiving, folding, sewing, hardware attachment, conditional edge coating or polishing, inspection, and sales packaging for a declared accessory specification.
Sports gloves are excluded. Leather garments, footwear, luggage, handbags, wallets, purses, general-purpose straps, saddlery, headgear, articles of furskin or artificial fur, accessories whose essential character is textile or plastic, and regulated protective equipment outside the declared clothing-accessory function are also excluded. Tanning and finishing hides into supplied finished leather, producing composition-leather sheet, textiles, polymers, metal hardware, chemicals, electricity, fuels, and packaging remain upstream unless physically performed inside the reporting facility.

boundary_losses_and_waste | manufacturing_losses | Include composition-specific cutting waste, unusable parts, hardware scrap, finishing residues, rejected products, packaging waste, and actual treatment routes in the process where they arise. | afw-pefcr-v3-1-2025 |
Allocation rules · 5
| Rule ID | Applies to | Rule | Source IDs |
|---|---|---|---|
allocation_subdivision_first | shared_foreground_processes | Use product-line or process sub-metering and subdivision before allocation whenever records distinguish the declared product. | afw-pefcr-v3-1-2025 |
allocation_comparable_units | shared_cutting_and_assembly | When subdivision is unavailable, allocate shared records by accepted units only for materially and technologically comparable accessories, then convert to the 1 kg reference flow using measured unit mass; otherwise use a documented causal driver. | afw-pefcr-v3-1-2025 |
allocation_energy_mix | multiple_sites_or_energy_sources | Build a production-weighted electricity mix from measured kWh and production mass; do not assign a preferred mix to one product without physical metering or equivalent records. | afw-pefcr-v3-1-2025 |
allocation_rework_and_waste | rework_and_rejected_product | Return successful rework to its originating process without counting another finished output; assign waste treatment to the generating process and disclose downstream recycling-credit treatment. | afw-pefcr-v3-1-2025 |
allocation_no_unrecorded_coproduct | saleable_offcuts_or_by_products | Report every saleable offcut or by-product explicitly; attempt subdivision first and obtain methodology review before applying non-physical allocation. | afw-pefcr-v3-1-2025 |
Validation rules · 10
| Rule ID | Applies to | Rule | Source IDs |
|---|---|---|---|
validate_reference_identity | reference_flow | Fail if the reference UUID, exact CPC 28242 classification, Product flow type, Mass UUID, Units of mass UUID, or kg unit differs from this PCR. | un-cpc-3-2025 |
validate_scope_exclusions | product_identity | Fail if the product is a sports glove, leather garment, footwear, bag, wallet, purse, general-purpose strap, saddlery, headgear, furskin article, or accessory whose essential character is not leather or composition leather. | un-cpc-3-2025, ec-access2markets-leather-classification |
validate_reference_amount | finished_reference_product | Require exactly 1 kg accepted net finished product; exclude packaging mass and retain packaging in separate rows when used. | afw-pefcr-v3-1-2025 |
validate_required_qualifiers | foreground_data_package | Fail completeness if an applicable required qualifier, specification revision, size, production site, period, edge-finishing route, or sports-glove exclusion is missing. | afw-pefcr-v3-1-2025 |
validate_bom_and_losses | material_mass_balance | Require at least 95% BOM coverage, all leather/composition leather/lining/reinforcement/metals, and reconciliation of returns, work in progress, cutting waste, hardware scrap, finishing residue, and rejected product. | afw-pefcr-v3-1-2025 |
validate_atomic_inventory | process_inventory | Fail if a selected flow combines multiple materials, electricity with another utility, multiple fuels, multiple refrigerants, multiple chemicals, multiple packaging materials, multiple waste identities, or multiple elementary emissions. | |
validate_conditional_routes | conditional_processes | Require route records or a documented not-applicable decision for finishing, each fuel, refrigerant, wastewater, sludge, and direct emission; do not infer their use from sector averages. | csir-clri-leather-goods-2016, afw-pefcr-v3-1-2025 |
validate_uuid_dual_check | non_reference_uuid | Fail if a non-reference UUID is populated without both a matching hybrid-search result and direct state-code-100 read for the same atomic flow. | |
validate_no_invented_quantities | foreground_amounts | Require collected foreground records or declared calculations; fail uncited defaults, reasoned estimates, AI-generated values, and unsupported ranges. | |
validate_bilingual_alignment | localized_markdown | Require identical ordered process ids, row ids, selected flows, UUIDs, controlled amount fields, rule ids, source ids, and source records in English and Chinese. |
