Raw furskins

1. Scope and Applicability

Covers undressed, untanned raw furskins suitable for furrier use: qualifying whole pelts and heads, tails, paws or cuttings. Declare actual species, lawful farm or wild source, fur-on configuration, whole/piece composition, grade, fresh or first-stage preserved state, net mass and handover gate. A lamb pelt belongs here only if its actual market identity is furrier-use furskin; an ordinary sheep/lamb raw hide remains outside. Exclude dressed or tanned fur, manufactured fur articles, detached hair, ordinary bovine/equine/sheep/goat raw hides and non-furrier other skins. Hair alone does not establish the category.

4. Measurement and Unit Rules

rule_id	Applies to	Required property	Required unit	Rule
m_net	each material lot	Mass	kg	Calibrated gross and tare; exclude packaging and free preservative; reconcile each actual material destination.
m_piece	piece-count markets	Mass and Number of items	kg and item	Record both mass and count on one homogeneous lot; calculate observed kg/item only for that species, grade, configuration and state.
m_state	preserved lots	Mass and moisture fraction	kg and kg/kg	Measure before/after state; do not convert fresh to preserved using a universal factor.
m_period	source and shared service	Time	reporting period	Link real cohort or capture season, service, outputs and replacement/termination to nonoverlapping periods.
inventory_reference_normalization	all inventory rows	Actual flow property	exchange unit per reference flow	The inventory and collection aggregation fields below express final amounts per declared reference flow. Keep all raw collection records, original denominator qualifiers, route/period strata, unit conversions and allocation requirements. For each flow, first obtain its attributable amount in its own numerator unit using the existing rules; then divide by the measured accepted reference-output quantity of the same scope and multiply by the declared reference quantity. Do not mix species, states, gates or incompatible routes; count transfers and shared burdens once. A missing, zero or untraceable accepted-output denominator is a blocking data-quality issue. Keep provisional QA ranges on their explicitly stated bases; they are not conversion factors or production defaults. These are final foreground-package contributions, not replacements for stage quantitative references or stage-native unit-process datasets. Retain stage records separately. Compute normalized amount = attributable raw amount * declared reference quantity / measured accepted final reference-output quantity. Apply normalization exactly once.
stage_throughput_linkage	stage records and final package contributions	Actual flow property and its stated raw basis	retain native numerator and stage denominator units	Keep the original lot, event, cohort, period and stage denominators with their units. Reconstruct the attributable numerator A with measured stage quantity Q_stage and documented attribution before final normalization. If a quoted amount a_B corresponds to an explicit stage basis B_stage (for example, 1000 kg), use A = a_B * Q_stage / B_stage. If r_stage is already an intensity in exchange-unit per stage-unit, instead use A = r_stage * Q_stage, with no second division by B_stage. A raw attributable total is used directly. Final contribution = A * declared reference quantity / measured accepted final output. Convert compatible units explicitly and apply each attribution/allocation share exactly once; never treat a quoted amount or intensity as a raw total. Link stage transfers, losses, rejects, stocks, shared services and allocation to the same actual route, period and final-output stratum. For a 1000 kg basis retain 1000 kg explicitly. Do not assume unit yield, equal fresh/dried mass, equal head mass, equal dose quality or interchangeable gates. Missing links, unsupported unit conversion, zero denominators and untraceable allocation block dataset production. Stage-native datasets retain their own stage reference; package contributions are a separate projection.

5. System Boundary

Boundary Abstraction

Field	Value
declared_starting_condition	Traceable farm cohort or lawful wild capture event with species and legal status.
starting_condition_role	Compatible upstream farm or wild-capture datasets carry actual source burdens. Foreground source event is an interface ledger when upstream already includes capture or slaughter; do not repeat exchanges. Wild route has no managed farm phase.
product_classification_scope	Raw, undressed and untanned furrier-suitable pelts and qualifying parts.
recursive_input_rule	Purchased same-category raw furskin retains supplier burden and is not newly captured here.
upstream_dataset_requirement	Source-specific farm or lawful capture inventory and actual slaughter/removal service; no automatic zero or whole-animal burden.
disclosure	Species, legality, route, actual co-products, configuration, condition, shared service, periods and gate.

Boundary Rules

rule_id	Applies to	Rule	source_ids
b_source	source	Separate farm from lawful wild capture. Include actual co-products only when independently marketed; do not repeat upstream animal or capture operations.	un-cpc-3-notes
b_remove	skin removal	Distinct capture/source and removal events; identify raw fur-on output, incidental tissue and losses, and handoff before first cleaning.	fao-hides-skins
b_condition	first preparation	Include only actual fleshing, cleaning and trimming; exclude dressing, tanning and manufacturing.	fao-hides-skins;eu-raw-furskin-heading
b_grade	grading	Separate accepted whole/pieces, saleable downgrade and waste, each with its own destination. Ordinary sheep hide cannot become furskin by hair alone.	un-cpc-3-notes;eu-raw-furskin-heading
b_preserve	treated lots	Fresh lots bypass; actual cold, drying or salt stabilization records before/after state, inputs and rejected material.	fao-hides-skins
b_gate	handover	Include protective presentation up to actual collection/curing gate; exclude distribution and downstream fur dressing.	un-cpc-3-notes

6. Process Inventory Structure

Process Map

process_id	process_name	inclusion	inclusion_condition	role	quantitative_reference
source	Farm or lawful wild source	required	every lot	Trace actual source events and co-products; no fictional husbandry for wild capture.	per kg node output
remove	Independent skin removal	required	every lot	Remove fur-on skin independently of source event and first preparation.	per kg node output
condition	First raw preparation	required	actual first preparation; ledger if none	First cleaning/fleshing/trimming without dressing or tanning.	per kg node output
grade	Furrier-use grading	required	every lot	Separate whole/piece accepted grades, downgraded sale and rejected waste.	per kg node output
preserve	Optional raw preservation	conditional	preserved lots only	Stabilize a usable raw state without dressing/tanning; fresh lots bypass.	per kg node output
handover	Protective handover	required	every accepted lot	Present fresh or preserved accepted raw skin at actual gate, excluding distribution.	per kg node output

Farm periods or wild-capture seasons, removal, cleaning and preservation can span periods. Attribute actual events and shared traps, tools or cold rooms to consuming nodes only once. These six nodes are responsibilities, not invented site activities.

7. Allocation and Co-product Handling

rule_id	Applies to	Rule	source_ids
a_source	source and remove	Enumerate earlier farm products at source, then skin and actual saleable terminal products at removal; each has a distinct handover and is counted once. Subdivide independently measured services; for inseparable source burdens use documented physical causality where defensible, otherwise contemporaneous net economic values of actual products with price sensitivity. Neither zero nor whole-animal burden is automatic.	fao-hides-skins
a_period	farm or wild route	Link breeding/growth, capture/slaughter, removal, replacement and termination to actual periods. Wild capture has no invented managed husbandry. Each input and output is attributed once.	un-cpc-3-notes
a_shared	shared traps, removal tools, cleaning and cold/drying rooms	Identify all consuming nodes and service periods. Prefer measured use; otherwise documented service hours or throughput, assigned once without upstream/foreground duplication.	fao-hides-skins
a_state	fresh/preserved; whole/piece	One lot has one marketed state and configuration at its gate. Do not count a pelt and its cuttings twice; allocate treatment only to treated lots.	eu-raw-furskin-heading

8. Foreground Data Collection, Calculation, and Quality Rules

Specific input identification before dataset completion

Identify the actual input for this operation from supplier specifications, equipment and primary records. This is a mandatory collection requirement, not an exchange. Before dataset completeness, represent each used material, formulated product, carrier or independently purchased service by one physically specific card with its native quantity/property; confirm a compatible UUID, or retain an explicit unresolved identity and do not claim a fully linked dataset. Do not substitute a conditional example for an unknown actual input, invent a recipe, omit required use or infer zero from missing records. Attribute shared use, reusable assets and inclusive services once; preserve the original stage/period and measured throughput link to final reference output. The former aggregate range is not a component limit or consumption default.

requirement_id	collection_protocol_id	Preserved collection scope
handover_packaging_specific_input	cp_handover	Operation handover: Identify single-use consumption or reusable turns; no packaging if absent. Denominator and scope requirements：per kg Protective handover output Raw quantity and calculation requirements: Identify single-use consumption or reusable turns; no packaging if absent. Original collection denominator kind: process_output. Original quantity method: Calculate the attributable final-package exchange under inventory_reference_normalization and stage_throughput_linkage using the matched raw records.

Route-specific energy identification requirements

Select energy exchanges from the actual product state, operation, equipment and supply records. The conditional cards below are not a mandatory or exhaustive fuel list. For each requirement, document applicability and the used carrier, supplier, service period, native quantity and allocation; add a separate physically specific card and verify its UUID for any actual input not yet represented. An unidentified input remains an explicit completeness gap, never a zero or a generic energy exchange. Evidence of manual work, ambient drying or a bypass can justify non-use only for the affected operation. Preserve every required operation even when no example card is supplied.

Separate purchased supply from on-site conversion. Link self-generated electricity internally to the foreground generator and count its actual fuel and emissions there once; do not also charge a purchased-electricity supply for the same internal transfer. Likewise do not count supplier-side fuel again with purchased heat. Reconcile shared meters and contractor-included energy against existing cards, with one physical quantity assigned once. Retain source quantities, output throughput, shared-service allocation and excluded post-gate activities. For each carrier, apply period/output attribution once and scale to the declared reference quantity using matched accepted final output in the same product unit; do not normalize an already normalized amount again. Process-native intensities require a measured throughput link to that final output. These requirements do not set a consumption default or certify dataset completeness.

requirement_id	collection_protocol_id	Required operation and evidence
preserve_energy_identification	cp_preserve	Actual raw-furskin preservation and holding: identify cold storage, drying or unpowered preservation from lot records, retaining shared-room attribution. No preservation route is mandatory. Denominator and scope requirements：per kg Optional raw preservation output Raw quantity and calculation requirements: Meter actual carrier and period; prevent shared-room double counting. Original collection denominator kind: process_output. (route-energy-fao)

Calculation Rules

rule_id	Applies to	Formula or rule	Inputs	Output	source_ids
c_ref	reference	Net sold mass = measured gross less package and separable free preservative; item count is not mass.	gross; tare; free preservative	kg as sold	fao-hides-skins
c_piece	counted items	Observed lot kg/item = measured homogeneous lot net mass / counted items; never reuse across species, grade, state or configuration.	mass; count; qualifiers	observed kg/item	eu-raw-furskin-heading
c_balance	each lot	Reconcile material output, residues and moisture/state differences with measured input; investigate gaps, not default yields.	input; output; state	kg ledger	fao-hides-skins
c_shared	shared service	Assign metered use or documented service-hour/throughput share once for each actual consumer and period.	burden; use; period	allocated burden	fao-hides-skins
handover_reject_specific_exchanges	handover	Enumerate rejected raw furskins and each actual packaging-waste material as separate actual streams. Measure each physical stream with its own composition, state, native unit, lot/period and destination; instantiate one atomic card per specific stream and boundary role. Distinguish waste transfer, purchased treatment and substance-specific discharge; do not treat a disposal service as the wastewater itself or duplicate treatment burdens. Keep stock, rework, marketed downgrade and discarded waste separate, and count physical mixtures once without also counting their components as additional exits. Retain the linked protocol and actual process attribution. Reconstruct each attributable raw numerator on its recorded stage basis, then normalize once to the matched accepted reference output. Missing identity, quantity, unit or destination blocks dataset completeness; absence requires evidence, not an assumed zero.	cp_handover	Separate atomic exchanges; completeness required
preserve_residue_identity_and_fate	preserve	Identify each actually separate material stream, composition, state and recipient. Keep spent preservation agents, brine, animal/plant material, packaging, drainage and intended co-products separate when separately handled; instantiate only streams actually evidenced at this operation. A physically mixed stream may have one composition-defined identity only with compatible treatment evidence, without also counting its components as additional exports. Distinguish marketed outputs, internal rework, waste transfer, purchased treatment and elementary discharge; do not duplicate treatment burdens. This replaces an ambiguous aggregate exchange, not the collection obligation. Before dataset completeness, create one concrete card per actual exchange, verify a compatible UUID or retain an explicit unresolved identity, and record quantity, unit, stage/period, destination and evidence. Reconstruct the raw attributable numerator from the linked protocol and normalize once to the matched accepted reference output. Missing data is not zero; no range of the former aggregate is an individual-stream default.	cp_preserve	Identity-specific exchanges and reconciled activity records
preserve_agent_identity_and_fate	preserve	For the original preserve_agent collection role at this operation, identify the actual physical form, species/material, composition, state and supply/treatment boundary before creating exchanges. Each seed lot, transplant, crown, cutting, larval stage, formulation, coating, preservative or separated residue actually used/generated requires its own concrete card where relevant to this role; these examples are alternatives, not a required recipe. Retain existing collection records and route-specific source evidence. Count-based planting records require measured or supplier-supported mass-per-unit when matched to a mass-based provider; retain count and mass as linked attributes rather than two purchases. Do not merge separate husk/shell or separate agents. A real mixed stream requires composition and recipient evidence and is counted once. Before completeness, record every applicable amount and native unit, link a compatible verified UUID or explicitly unresolved identity, preserve stock/return attribution, and normalize the attributable raw quantity once to the accepted reference output. Missing records are not zero; aggregate ranges are not individual-input defaults.	cp_preserve	Identity-specific exchanges and reconciled activity records

Data Quality Requirements

requirement_id	Applies to	Requirement	Evidence
dq_identity	every lot	Verify species, legality, furrier-use quality, whole/piece composition and undressed state; sheep hide is not inferred to be furskin.	authority and grade/sale record
dq_mass	all material	Calibrated mass and destination; no parent pelt and cutting double count.	scale and balance
dq_period	source and shared assets	Actual cohort/season, period and consuming node, including replacement or termination.	event and asset ledgers
dq_state	preservation	Actual before/after state; no universal fresh-to-preserved conversion.	treatment and mass records
dq_uuid	exchange generation	Resolve a concrete compatible platform identity; blank candidate identity is not final exchange permission.	detail and support-row evidence

9. Validation Rules

rule_id	Applies to	Rule	source_ids
v_scope	sold lot	Reject tanned, dressed, manufactured or hair-bearing non-furrier goods; verify lawful source and actual furrier-use whole/piece identity.	un-cpc-3-notes;eu-raw-furskin-heading
v_balance	each lot	Reconcile source, removed, prepared, accepted, downgrade, waste, treated and sold mass at their measured states.	fao-hides-skins
v_route	farm/wild	No farm animal input on wild route; actual co-products and source burden once; no upstream capture/slaughter duplication.	un-cpc-3-notes
v_period	shared service	Source event and each shared trap, removal, cleaning or cold/dry service have one period and one attributed consumer share.	fao-hides-skins
v_binding	all cards	conditional product inputs require actual concrete selection; uncovered UUIDs need detail confirmation. Mixed raw/dressed count-based candidates cannot bind a raw Mass reference.
v_foreground_emission_responsibility	Actual operated nodes and linked services	Record responsibility for on-site fuel combustion and refrigerant leakage when applicable: either quantified foreground emissions or a named linked process explicitly covering them, never merely a fuel-supply or electricity-production input. Assess special-taxon biological and residue emissions using species/route evidence, without a generic livestock factor. Identify any unresolved pathway and withhold a completeness claim; document supported absence and prevent duplicate upstream/downstream accounting.
