# Products n.e.c. of fish, crustaceans, molluscs or other aquatic invertebrates; dead fish, crustaceans, molluscs or other aquatic invertebrates unfit for human consumption

## 1. Scope and Applicability

This PCR covers the exact generic scope of CPC 3.0 subclass 21299. It applies to otherwise unclassified products of fish, crustaceans, molluscs or other aquatic invertebrates and to dead aquatic animals explicitly unfit for human consumption when they leave the foreground site as a non-food product. The product identity, legal status, reason for non-food disposition, intended non-food use, physical state and route shall remain explicit. The reference flow shall never be described, validated or modelled as food.

Edible fishery products, live aquatic animals, inedible flours, meals and pellets classified in CPC 21291, and outputs that have legal waste status at the reference point are excluded. Upstream capture, landing, aquaculture and supplier processing are represented by linked upstream datasets when applicable, not recreated inside this foreground boundary. This candidate supports direct dispatch and one declared conditioning route; route inventories shall not be combined as if simultaneous.

## 2. Product Category Identity

| covered_products | Otherwise unclassified non-food products of fish, crustaceans, molluscs or other aquatic invertebrates; dead aquatic animals unfit for human consumption and supplied as products for a declared non-food use |
| excluded_products | Products intended or represented as food; live aquatic animals; CPC 21291 inedible flours, meals and pellets; packaging; free liquid or removable ice reported separately; outputs having legal waste status at the reference point |
| representative_product | A lot of dead or derived aquatic material, explicitly classified as non-food, dispatched in bulk or packaged form for a declared non-food use |
| production_route | Exactly one route code per dataset: `direct_dispatch`, `chilled_or_iced`, `frozen_or_glazed`, `salted_or_brined`, or `dried_or_other_stabilized` |
| market_state | Non-food product at the foreground site gate; whole, pieces, mixed aquatic material or another declared form, with preservation state and destination declared |

## 3. Reference Flow

| Field | Value |
| --- | --- |
| What | Provision of a qualified CPC 21299 aquatic product explicitly intended for non-food use |
| How much | 1 kg net product mass at the foreground site gate |
| How well | Product identity, non-food status and reason, intended use, route, form, condition and applicable mass qualifiers are declared and traceable to the lot |
| How long or cycle | One production lot at final mass determination and dispatch; no service duration is implied |
| reference_flow_link | The functional unit is realized by the single Tiangong reference product flow below |

| Field | Value |
| --- | --- |
| Reference amount | 1 kg qualified product net mass |
| Reference product flow | Products n.e.c. of fish, crustaceans, molluscs or other aquatic invertebrates; dead fish, crustaceans, molluscs or other aquatic invertebrates unfit for human consumption `96594bec-f1eb-4559-b4b2-2be03ec8f1cf` |
| Reference flow property | Mass `93a60a56-a3c8-11da-a746-0800200b9a66` |
| Reference unit group | Units of mass `93a60a57-a4c8-11da-a746-0800200c9a66` |
| Reference unit | kg |
| Required qualifiers | non-food status and reason for unfitness or non-food disposition; intended non-food use and destination; aquatic taxon or declared mixed-material composition; whole, pieces or other physical form; route code; preservation and temperature state; source legal status as product or waste; net product mass and weighing basis; moisture content or declared wet/dry basis when material; salt content or brine salinity for `salted_or_brined`; gross and deglazed net mass plus deglazing method for `frozen_or_glazed`; drained mass, gross mass and draining method for product packed in liquid; packaging state; site, geography and lot period |

When constructing a foreground data package, the items listed in `Required qualifiers` shall be declared in dataset metadata, process notes, reference flow comments, product descriptions or equivalent fields. Missing applicable qualifiers make the reference flow incomplete. Packaging, separately removable glaze or ice, and free packing liquid are excluded from the 1 kg net product mass; their masses remain separate inventory flows. If the commercial record uses a different basis, both the commercial mass and the converted reference net mass shall be reported.

## 4. Measurement and Unit Rules

| rule_id | Applies to | Required property | Required unit | Rule |
| --- | --- | --- | --- | --- |
| `reference_net_mass` | Reference product | Mass `93a60a56-a3c8-11da-a746-0800200b9a66` | kg | Normalize all inventory to 1 kg net product mass after excluding packaging, free packing liquid and separately removable ice or glaze. Record calibrated gross, tare and excluded masses. |
| `moisture_basis` | Wet, dried or composition-sensitive product | Mass `93a60a56-a3c8-11da-a746-0800200b9a66` | kg | Declare whether mass is as-received, wet, drained or dry; measure moisture on a representative lot sample when conversion between wet and dry bases materially changes results. |
| `salt_brine_basis` | `salted_or_brined` route | Mass `93a60a56-a3c8-11da-a746-0800200b9a66` | kg | Report salt addition and removed or retained brine separately; declare product salt content or brine salinity, sampling method and whether the value is measured or calculated. |

## 5. System Boundary

The foreground boundary is governed by the following rules:

| rule_id | Applies to | Rule | source_ids |
| --- | --- | --- | --- |
| `boundary_foreground_gate` | Foreground system | Begin with receipt of the declared aquatic source material or supplied CPC 21299 product and include on-site receipt, non-food identity verification, sorting, the one selected conditioning route, final mass determination, packaging when used, and handling of rejects, wastewater or spent brine to the next treatment or transfer interface. | `codex-cxc-52-2003`, `eu-pef-2021-2279` |
| `boundary_non_food_identity` | All product-bearing processes | Preserve explicit non-food identity and intended non-food destination throughout; Codex handling concepts are used for traceability, temperature and measurement practice only and shall not be interpreted as food conformity. | `unsd-cpc-3-0-21299`, `codex-cxc-52-2003` |
| `boundary_route_exclusivity` | Conditioning | Select exactly one route code. Include `conditioning_stabilization` only when the route is not `direct_dispatch`, and record only inputs and outputs used by the selected route. | `eu-pef-2021-2279` |
| `boundary_exclusions` | Foreground system | Exclude capture, aquaculture, landing, supplier processing, distribution after the site gate, non-food use and end-of-life; link material upstream datasets and disclose any study-specific extension instead of silently truncating it. | `eu-pef-2021-2279` |

### Boundary Abstraction

| Field | Value |
| --- | --- |
| declared_starting_condition | Aquatic material or an existing CPC 21299 product received at the foreground site with supplier, lot, physical state, temperature or preservation state, legal product-or-waste status, and reason for non-food disposition declared |
| starting_condition_role | Foreground input gate for non-food classification, optional conditioning and dispatch |
| product_classification_scope | Exact generic CPC 3.0 subclass 21299 only; CPC 21291 meals, flours and pellets and food products remain outside scope |
| recursive_input_rule | A purchased input already within CPC 21299 remains an explicit product input and is linked once to its supplier dataset; do not reproduce the same category's upstream production recursively inside the receiving process |
| upstream_dataset_requirement | Use supplier- or route-representative upstream datasets for capture, aquaculture, landing, earlier processing, transport to site and any supplied CPC 21299 input; disclose gaps and substitutions |
| disclosure | Declare source identity, legal status, non-food reason and destination, route code, excluded upstream stages, mass basis, moisture, salinity or salt content, glaze or drained mass where applicable, packaging and all waste or recovery destinations |

| `conditioning_stabilization` | Route-specific conditioning or stabilization | conditional | Include only for `chilled_or_iced`, `frozen_or_glazed`, `salted_or_brined`, or `dried_or_other_stabilized`; exactly one route is selected | Preserve or adjust the declared non-food product state | kg route output |
| `final_mass_dispatch` | Net-mass determination, packaging and dispatch | required | Always; packaging inputs are recorded only when used | Produce the qualified non-food reference product at the site gate | 1 kg qualified net product |

## 7. Allocation and Co-product Handling

Apply the following hierarchy:

| rule_id | Applies to | Rule | source_ids |
| --- | --- | --- | --- |
| `allocation_subdivision` | Shared foreground operations | Avoid allocation by separate route batches, direct metering or process subdivision wherever technically feasible. | `eu-pef-2021-2279` |
| `allocation_output_status` | Products, co-products and waste | Classify each output from documented intended use, legal status and destination. Non-food or unfit-for-human-consumption status alone does not make an output waste and does not justify zero burden. | `eu-pef-2021-2279` |
| `allocation_fallback` | Unavoidable shared burdens | When subdivision is not feasible, use a demonstrable physical causal relationship; if none can be established, use an economic or other justified relationship and disclose the method, prices or physical parameters, period and sensitivity. | `eu-pef-2021-2279` |
| `allocation_recovery` | Recycling, recovery or waste treatment | Keep treatment burdens and recovered-material or energy benefits consistent with the selected PEF-compatible end-of-life approach; do not add an avoided-product credit without declaring the substituted function and method. | `eu-pef-2021-2279` |

| `validate_reference_mass` | Reference flow | The reference amount equals 1 kg qualified net product using the stated UUIDs and Mass/kg basis; packaging, removable glaze or ice and free liquid are excluded, and moisture, salt or salinity, deglazed or drained mass qualifiers are present when applicable. | `codex-cxc-52-2003`, `mass-balance-identity` |
| `validate_route_exclusivity` | Process map | Exactly one route code is declared; conditioning inventory is absent for `direct_dispatch`, and only the selected route's inputs and outputs are present otherwise. | `eu-pef-2021-2279` |
| `validate_mass_balance` | Receipt, conditioning and dispatch | Lot and batch mass balances reconcile within the site's documented scale and inventory uncertainty; any unresolved difference is quantified, investigated and disclosed rather than hidden in the reference product. | `mass-balance-identity`, `eu-pef-2021-2279` |
| `validate_allocation_destinations` | Shared burdens and outputs | Subdivision is attempted first; every co-product and waste has legal status and destination; any fallback allocation or recovery credit is justified, parameterized and sensitivity-tested. | `eu-pef-2021-2279` |

## 10. Published Dataset Profile

| Field | Value |
| --- | --- |
| dataset_role | Foreground production dataset for an exact generic CPC 21299 non-food aquatic product |
| downstream_use | `secondary_dataset`; `background_dataset`; input to `process` and `lifecyclemodel` projections |
| allowed_use | Modelling a declared non-food CPC 21299 product from the stated receiving condition through the site gate for the same route, mass basis, legal status and geography |
| excluded_use | Food products; CPC 21291 meals, flours or pellets; undeclared route mixtures; substitution for capture, aquaculture, rendering, feed, fertilizer, disposal, use or end-of-life datasets without an explicit scope extension |
| required_metadata | Canonical PCR id, CPC reference, product UUID, Mass and unit-group UUIDs, non-food reason and destination, taxon or composition, legal status, route, condition, site and period, upstream links, net-mass basis, moisture, salinity or salt, glaze or drained mass where applicable, packaging, allocation and waste destinations |
| required_quality_disclosure | Primary-data share, route and seasonal coverage, calibration and test methods, mass-balance differences, reasoned-estimate substitutions, secondary-dataset quality, allocation sensitivity and limitations |
| update_trigger | Replace each provisional reasoned estimate when reviewed route- and site-specific evidence is available or before active review; update when product legal status, route, reference-flow UUID, measurement method, allocation method or material process technology changes |
