Whole-pelt natural fur coat manufacturing

1. Scope and Applicability

This method covers new whole-pelt natural fur coats made from purchased dry dressed hair-on skins by matching, skin-side cutting, sewing and lining assembly, with water-only blocking when used. The specified route has a finished 100% cotton lining, polyester sewing thread and steel hook-and-eye closures. It excludes headgear, accessories, blankets, artificial fur, hair-off leather, raw-skin dressing, remanufacture, knitted fur strips, letting-out, shearing, chemical garment cleaning, steam glazing and on-site dyeing. Such steps require an expanded process-specific inventory before this method is used. CPC is broader than this selected route. No default recipe, energy use, yield, warmth rating or lifetime is established. [Sources: cpc30-notes; usu-fur-2025; fic-coat].

4. Measurement and Unit Rules

rule_id	Applies to	Required property	Required unit	Rule
reference_mass	reference product	Mass 93a60a56-a3c8-11da-a746-0800200b9a66	kg	Use calibrated net batch weighing of accepted conditioned coats, excluding packaging. Do not convert pelt count or garment count to mass without actual same-batch weighing.
energy_identity	sewing_electricity	Net calorific value 93a60a56-a3c8-11da-a746-0800200c9a66	MJ	Retain the public electricity reference property and energy unit; meter kWh and convert with exactly 3.6 MJ/kWh. Never rewrite the property as Mass.
water_mass	blocking_water	Mass	kg	Weigh water directly; volume readings require measured density at the recorded temperature, not an assumed density. Do not confuse product water, resource withdrawal, effluent and air vapour.
vapour_mass	blocking_vapour	Mass	kg	Calculate actual air-vapour mass from the independently measured liquid/moisture records in cp_water and water_balance; direct weighing of vapour is not required. Retain uncertainty, receiving air medium and investigation of negative/unexplained residuals; do not equate all supplied water with evaporation.

5. System Boundary

Boundary Abstraction

Field	Value
declared_starting_condition	Dry dressed hair-on skins and finished lining/components received at garment factory. All tanning, dyeing and supplier finishing already completed.
starting_condition_role	manufacturing_input
product_classification_scope	Narrower whole-pelt lined-coat route within CPC 3.0 28320; no accepted classification edge implied.
recursive_input_rule	Purchased same-category coat or preassembled shell must be separately declared as an intermediate with its upstream burden; do not recursively apply virgin-pelt input quantities or count that shell twice. Used coats are excluded.
upstream_dataset_requirement	If extending beyond this gate-to-gate boundary, link state/species/origin-compatible dressed-pelt, finished-fabric, component, electricity and water supply datasets, and actual transport. Farming/trapping, skin dressing and cotton/fibre production are upstream, not zero burden.
disclosure	Declare operations, incoming processing state, supplier boundaries, exclusions, outsourced sewing and wastewater handling. Do not label the foreground inventory complete cradle-to-gate.

rule_id	Applies to	Rule	source_ids
boundary_route	all processes	Include matching, cutting, actual rework, seam sewing, lining/closure assembly and acceptance/packing. Blocking is conditional; drying here is passive. Other chemicals, active dryers or steam operations require added explicit process and atomic exchanges before use.	usu-fur-2025; fic-coat
boundary_releases	site releases	Purchased water is a technosphere input. No washing bath or routine process effluent is assumed in this route. If blocking runoff is discharged, identify its actual receiving treatment, amount and chemistry separately; wastewater treatment is not direct freshwater emission. Meter site cleaning separately and disclose its boundary.
boundary_end	factory gate	Retail delivery, wearing, cleaning, cold storage by consumers and end-of-life are excluded; no longevity or avoided-product credit is claimed. Manufacturing transport and supplier modules must be disclosed if appended.

6. Process Inventory Structure

Process Map

process_id	process_name	inclusion	inclusion_condition	role	quantitative_reference
cut	Receipt, matching and manual cutting	required	Declared new-coat route.	foreground_production	per 1 kg reference flow
block	Water-only blocking and passive drying	conditional	Actual water-only blocking is performed.	foreground_production	per 1 kg reference flow
sew	Fur-seam sewing and lining/closure assembly	required	Declared new-coat route.	foreground_production	per 1 kg reference flow
pack	Inspection, rework accounting and packing	required	Declared new-coat route.	foreground_production	per 1 kg reference flow

All stage exchanges are normalized to the same accepted finished-coat net mass. Internal matched pelts, blocked panels and sewn shells are linked by batch travellers, not counted as extra external products. Quantities have no default values. Other actual exchanges must be individually added; absence needs records, not assumed zero.

7. Allocation and Co-product Handling

rule_id	Applies to	Rule	source_ids
allocation_subdivide	shared equipment	Use batch submetering and separately weighed issues first. For unavoidable shared electricity, collect workstation operating and idle times and measured loads to justify attribution; record total and assigned quantities and residual.	ghg-product-2011
allocation_offcuts	saleable offcuts	Distinguish retained internal offcuts, externally saleable co-products and discarded waste. Internal reuse is an internal transfer. Avoid co-product allocation through subdivision; otherwise justify a physical relationship, or documented economic allocation when no physical basis is defensible. Disclose prices/period, masses, fractions and sensitivity; no automatic avoided-product credit.	ghg-product-2011
allocation_upstream	dressed pelts	Retain the upstream dataset allocation for animal production and dressing, documenting its scope and origin. Garment assembly does not establish agricultural co-product allocation by coat mass.

Calculation Rules

rule_id	Applies to	Formula or rule	Inputs	Output	source_ids
normalize_batch	all inventory rows	q_ref = Q_pool / M_accepted. Define one homogeneous reporting pool by site, period, species, supplied state and declared coat configuration/size mix. Q_pool sums each row’s attributable measured or calculated quantities in its native unit across every included batch, including wholly rejected batches, rework and attributable maintenance; exclude duplicate internal transfers. M_accepted is the sum of accepted net finished-coat kg from cp_output for the same pool, counting finally accepted reworked output once. Never divide a zero-output batch separately or omit its burdens. M_accepted must be positive; if the whole pool has no accepted output, retain absolute quantities, report normalization unavailable and require review, not zero or a fabricated denominator.	Q_pool; M_accepted; cp_output; batch and reporting-pool ledger	exchange per 1 kg reference flow
electricity_conversion	sewing_electricity	MJ = kWh × 3.6; use attributable measured electricity, retaining its public Net calorific value reference property.	kWh; cp_electricity	MJ
water_balance	blocking_vapour	Evaporated water = applied water minus retained moisture increase, recovered water and independently measured runoff; a negative residual or unexplained imbalance requires investigation, not zero clipping.	cp_water	batch air water-vapour mass before normalize_batch

Data Quality Requirements

requirement_id	Applies to	Requirement	Evidence
dq_configuration	all batches	Keep species, incoming processing state, whole-pelt technique and complete bill of materials consistent; do not mix cotton and silk-lined configurations without separate records.	supplier declarations and batch travellers
dq_balance	all processes	Reconcile material issues, internal reuse, inventory change, accepted mass, rejects, separate wastes and water evaporation; identify losses, moisture effects and uncertainty without inventing emission factors.	weighing and utility reconciliation
dq_coverage	reporting period	Disclose site, actual dates, batch/size coverage, contractors, meter completeness, exclusions, allocation, identity gaps and data age. Do not replace missing records with zero.	production register and quality file

9. Validation Rules

rule_id	Applies to	Rule	source_ids
validate_reference	finished_coat	Verify 1 kg complete accepted conditioned coat net output with all qualifiers and cp_output; dressed pelt, artificial fur and headgear cannot substitute for the coat.	cpc30-notes
validate_rows	all inventory rows	Require atomic identity, same accepted-output denominator, compatible public reference property/unit and attributable collection records. Every active exchange needs an amount; unresolved UUIDs are declared identity gaps, not automatic proxies. Verify pool membership and inclusion of wholly rejected batches; require positive M_accepted before producing any normalized result, and retain absolute inventories when no accepted output exists.
validate_route	block; sew	Check conditional blocking, oil and waste applicability against actual records; verify immediate air-vapour medium and CN <1 kV electricity. Any added chemical or effluent route needs explicit exchanges and treatment boundary before dataset acceptance.
validate_balance	batch records	Investigate mass/water residuals, output acceptance and rework; retain calibration and uncertainty. Factory quality acceptance does not establish health, legal or methodological approval.
