# Other edible products of animal origin n.e.c.

## 1. Scope and Applicability

This residual method covers one concrete edible animal-origin good not classified elsewhere in CPC 3.0. Each lot requires a named product and animal source, legal provenance, human-food eligibility, sold state, classification decision and actual gate. Edible bird nests, turtle eggs, royal jelly and propolis are possible examples only after individual classification and legal review; none stands for the whole class. The method does not assert their legality in any jurisdiction. Exclude non-living edible insects (02931), natural honey, ordinary bird eggs, raw milk, meat, snails, non-food goods and differently classified finished food. A species-free average or universal yield is invalid.

A compatible source-specific upstream record carries source production and its biological phases. Foreground collection is an independent interface; first preparation and preservation are performed only when real, followed by food grading and protective handover. Purchased goods enter at their actual later node with upstream burdens; do not invent another harvest. The gate is the real production or first-collection handoff, excluding distribution, retail and further food manufacture.

## 3. Reference Flow

| Field | Value |
| --- | --- |
| What | One named, classification-confirmed residual edible animal-origin product. |
| How much | 1 kg net saleable product excluding package and separately removed inedible matter. |
| How well | Declare animal species/source, legal and food status, grade, moisture, physical state and gate. |
| How long or cycle | Link source establishment, productive/termination periods, collection and shared services to real lots once. |
| reference_flow_link | `sold` |

| Field | Value |
| --- | --- |
| Reference amount | 1 |
| Reference product flow | Source-, state- and gate-qualified other edible animal-origin good |
| Reference flow property | Mass `93a60a56-a3c8-11da-a746-0800200b9a66` |

| Reference unit | kg |
| Required qualifiers | named good; animal species/source; lawful provenance; CPC and food status; moisture; grade; sold state; net/tare; gate; period |

## 4. Measurement and Unit Rules

| rule_id | Applies to | Required property | Required unit | Rule |
| --- | --- | --- | --- | --- |
| m_net | sold lot | Mass | kg | Calibrated gross minus package tare and separately removed inedible matter; disclose retained moisture. |
| m_states | each performed node | Mass | kg | Reconcile before/after state and actual additions/removals; never apply a cross-product yield. |
| m_period | source and shared assets | Time | period | Assign source, collection, replacement and shared-service events to their actual period once. |
| `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 | A named lawful animal, colony or nest-source good at actual collection, or documented purchased material in its entering state. |
| starting_condition_role | Compatible source-specific upstream dataset carries source production, phases and actual co-products; foreground begins at independent collection or purchased handoff. |
| product_classification_scope | CPC 02939 only after checking exclusions and all more specific CPC positions for the named good. |
| recursive_input_rule | Purchased same-category goods retain upstream burden and enter their true later node, never a second fictitious collection. |
| upstream_dataset_requirement | Source/species, legal chain, source periods, real output set, incoming state and burden coverage. |
| disclosure | Named good, classification rationale, legal/food status, actual route, periods, output set, gate and unresolved identities. |

### Boundary Rules

| rule_id | Applies to | Rule | source_ids |
| --- | --- | --- | --- |
| b_identity | each lot | Require concrete good, lawful provenance, food eligibility and residual CPC classification; examples do not prove 02939. | un-cpc-3;eu-residual |
| b_collect | source collection | Distinguish actual animal, colony or nest production from independent removal, incidental losses and collected handoff; purchased goods bypass collection. | eu-residual |
| b_prepare | first preparation | Include actual first cleaning/separation, water or service inputs, collected/prepared handoff and non-food rejects; bypass when absent. | eu-residual |
| b_preserve | preservation | Identify usable before/after state, actual energy and services, residues, evaporation and rejects; bypass when absent. | eu-residual |
| b_grade | grades and gate | Enumerate accepted, separately saleable downgrade and ineligible reject with distinct destinations; protect to actual gate, excluding freight. | un-cpc-3 |

## 6. Process Inventory Structure

### Process Map

| process_id | process_name | inclusion | inclusion_condition | role | quantitative_reference |
| --- | --- | --- | --- | --- | --- |
| collect | Source-qualified collection | conditional | actual new lawful source; purchased material bypasses collection | Independent source-to-collected handoff; incidental loss separate | kg output of node |
| prepare | First hygienic preparation | conditional | actual cleaning or separation | Raw collected to prepared state; water and rejects recorded | kg output of node |
| stabilize | Optional preservation | conditional | actual permitted stabilizing intervention | Usable before/after states, energy and reject recorded | kg output of node |
| grade | Food-grade sorting | required | concrete edible lot | Accepted, saleable lower grade and ineligible reject have separate destinations | kg output of node |
| handover | Protective presentation and handover | required | saleable food-qualified lot | Actual package/reuse role, net product and source/first-collection gate | kg output of node |

One concrete source route is required. Nest, secretion and egg collection have no common biological operation or yield. Enumerate every real marketed source output at its own handoff, plus incidental residues; make a source-specific attribution decision. Each conditional node has a measured entering and leaving state and is bypassed if not performed. Shared collection, cleaning, chilling, sorting and packing assets attach to actual nodes and periods once. A downgraded grade is a second Product only when independently saleable and food-eligible; ineligible rejects are never food outputs.

###### Electricity at the equipment supply point (`energy_electricity`)

**Collection scope and applicability for energy.** The following concrete identities have separate cards and apply only when use or generation is evidenced inside the original process scope. They are not mandatory inputs or a default recipe. Document non-use; missing records are not zero. Add a separate concrete card for any other actual material instead of substituting one of these names or UUIDs. Preserve attribution and boundaries and avoid double counting components included in outsourced services.

## 7. Allocation and Co-product Handling

| rule_id | Applies to | Rule | source_ids |
| --- | --- | --- | --- |
| a_source | actual source output set | Enumerate each intended product, amount and gate. Use measured causal attribution when supported; otherwise document period-specific economic allocation with sensitivity. Do not assign automatic zero or entire source burden to 02939. | eu-residual |
| a_grade | grades and residue | Accepted and separately saleable downgraded goods have disjoint masses/destinations; non-food rejects and incidental residue are not extra edible products. | un-cpc-3 |
| a_period | phases and shared service | Index source establishment/productive/replacement/termination periods; assign observed shared-service time or throughput to consuming nodes/lots once with evidence. |  |

Concrete cards do not inherit numerical ranges from the former aggregate card. Determine quantities from original records, stock/meter reconciliation and the declared reference flow; no default quantity or numeric screen is supplied without evidence matching the identity, unit, period and boundary. Missing range evidence is a quality disclosure, not zero use or proof of completeness.

## 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 |
| --- | --- | --- |
| `package_specific_input` | `cp_handover` | Operation handover: Record package material, tare and reuse or single-use service. Denominator and scope requirements：per kg output of the corresponding process Raw quantity and calculation requirements: Measure the actual flow by source, lot and period; bypassed conditional nodes are not modelled. 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. |

### Calculation Rules

| rule_id | Applies to | Formula or rule | Inputs | Output | source_ids |
| --- | --- | --- | --- | --- | --- |
| c_net | sale lot | Net qualified good = gross - package tare - separately removed inedible matter; use actual moisture, not a universal dry conversion. | cp_handover | kg net good |  |
| c_balance | performed nodes | Reconcile material input and additions with food outputs, rejects, measured water loss and stock change; investigate residual. | cp_collect;cp_prepare;cp_stabilize;cp_grade;cp_reject | kg balance residual |  |
| c_period | source and shared assets | Link each source phase and shared service to real lots and periods, allocating once by observed use. | cp_collect;cp_prepare;cp_stabilize;cp_handover | burden/kg |  |
| c_norm | concrete exchange | Divide attributable exchange by positive net mass of the same named good/source/state/gate lot. | cp_handover | unit/kg good |  |

### Data Quality Requirements

| requirement_id | Applies to | Requirement | Evidence |
| --- | --- | --- | --- |
| q_identity | each lot | Verify residual CPC classification, named good/species, legal chain, food eligibility, sold state and gate. | source, legal, food and dispatch records |
| q_mass | each lot | Calibrate gross/tare and before/after mass; assay relevant moisture/contamination. | scale, assay and balance |
| q_allocation | source and shared assets | Complete real output set, phases, attribution driver and nonduplicated asset burden. | output, service and period ledgers |
| q_uuid | each concrete exchange | Confirm flow type, role, source, state, gate, property and unit support before fixed UUID. | detail verification evidence |

## 9. Validation Rules

| rule_id | Applies to | Rule | source_ids |
| --- | --- | --- | --- |
| v_scope | reference lot | Reject generic other-animal averages, insects, honey, ordinary eggs, raw milk, meat, snails, non-food goods and elsewhere-classified food; require legal and food evidence. | un-cpc-3;eu-residual |
| v_route | source | Require real source or documented purchased input; reject fictitious common biology, duplicate collection and unperformed treatment. | eu-residual |
| v_balance | each lot | Reconcile performed states, additions/removals, grade/reject destinations and net dispatch. |  |
| v_allocation | periods/outputs | Reject omitted real co-products, duplicate grades, zero/full automatic burden and duplicate shared service. |  |
| v_identity | final exchange | Verify named good, source, state, gate, direction/type and property/unit support. |  |
| `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. | |
