# Norway lobsters, frozen, dried, salted or in brine

## 1. Scope and Applicability

This PCR supports foreground data packages for raw Norway lobster (*Nephrops norvegicus*), in shell or not, preserved by one declared route: frozen, dried, salted, or in brine. It covers processor-gate operations from receipt of eligible live, fresh, or chilled raw material through preparation, the declared preservation route, packaging, and any on-site storage before dispatch. Capture, aquaculture, landing and inbound transport are upstream dataset inputs; distribution, retail, cooking, consumption and end-of-life are outside the foreground boundary.

Cooked, smoked, canned, or otherwise processed Norway lobster; other lobster species; and route mixtures that cannot be separated into route-specific inventories are excluded. The foreground data package shall not average frozen, dried, salted and brined production unless each route is separately modelled and the aggregation purpose and weighting records are disclosed.

## 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 | Normalize all inventory results to 1 kg net product mass at processor-gate dispatch.

## 7. Allocation and Co-product Handling

| rule_id | Applies to | Rule | source_ids |
| --- | --- | --- | --- |
| `allocation_route_separation` | Multiple preservation routes or materially different presentations | Avoid allocation by subdividing route, line, batch and presentation inventories. Do not allocate a combined multi-route inventory to the reference product when route-specific records can be obtained. | `eu-pef-2021-2279` |
| `allocation_co_products` | Marketed shell, meat, residual or other co-product | First seek process subdivision or a documented physical causal relationship. If this is not feasible, use an economic relationship based on contemporaneous net revenue and report prices, period and sensitivity; do not assign zero burden solely because an output is secondary. | `eu-pef-2021-2279` |
| `allocation_shared_resources` | Shared water, energy, packaging equipment and storage | Prefer direct metering. Otherwise use a documented physical driver such as equipment time and load, line throughput, occupied cold-store capacity and storage duration; disclose the driver and test whether it materially changes results. | `eu-pef-2021-2279` |
| `allocation_waste_treatment` | Rejects, wastewater, spent brine, packaging scrap and refrigerant losses | Do not treat waste as a co-product unless a documented market function exists. Include in-boundary collection or treatment operations and emissions, and disclose any downstream waste-treatment dataset and recycling or recovery convention. | `eu-pef-2021-2279` |

### Calculation Rules

| rule_id | Applies to | Formula or rule | Inputs | Output | source_ids |
| --- | --- | --- | --- | --- | --- |
| `calc_net_product_mass` | Packaged reference product | Net product mass = gross filled-container mass - packaging tare - free preserving brine - external ice or glaze. Use the legally applicable drained or deglazed method and retain shell/presentation state. | gross mass; packaging tare; free brine mass; external ice/glaze mass | kg net product mass | `codex-cxs-95-1981` |
| `calc_route_yield` | Receipt, preparation and preservation | Yield = net preserved product mass / eligible raw lobster input mass for the same lot and route. Report residual destinations and explain unreconciled mass; do not use an uncited default yield. | eligible raw mass; net preserved mass; residual and discharge records | route-specific kg/kg yield and reconciliation | `codex-cxc-52-2003` |
| `calc_inventory_normalization` | All inventory rows | Normalized amount = allocated foreground amount / dispatched net product mass for the same route, site and period. | foreground amount; allocation record; dispatched net product mass | amount per 1 kg reference flow | `eu-pef-2021-2279` |
| `calc_refrigerant_loss` | Refrigeration equipment | Refrigerant loss = opening stock + purchases + charged quantity - recovered quantity - closing stock, reconciled with service records and restricted to in-scope equipment. | substance-specific stock and service fields | kg refrigerant emitted by substance before allocation | `eu-pef-2021-2279` |

### Data Quality Requirements

| requirement_id | Applies to | Requirement | Evidence |
| --- | --- | --- | --- |
| `dq_identity_traceability` | Raw input and reference product | Demonstrate *Nephrops norvegicus* identity, lot traceability, route, raw state, presentation and processor-gate net-mass basis. | Supplier/landing record, species identification, lot record, label and release record; `unsd-cpc-3-0`; `codex-cxs-95-1981` |
| `dq_temporal_geographic_technology` | All foreground data | Use data representative of the declared sites, technologies, seasonal production and reporting period; disclose gaps, outsourced operations and substitutions. | Site list, equipment register, production calendar and representativeness assessment; `eu-pef-2021-2279` |
| `dq_completeness_reconciliation` | Mass, water, energy, packaging, waste and refrigerant records | Reconcile inputs and outputs at route and reporting-period level. Investigate rather than silently close material gaps; report data coverage and estimation share. | Mass/water/energy balances, invoices, meter coverage and gap log; `eu-pef-2021-2279` |
| `dq_measurement_quality` | Metered and weighed records | Retain units, calibration status, sampling frequency, conversion factors and responsible data owner. | Calibration certificates, raw exports, scale logs and calculation workbook |
| `dq_food_safety_records` | All declared routes | Retain validated route-specific controls, monitoring, corrective action and release evidence. Frozen product records shall demonstrate the applicable freezing and storage condition. | HACCP and release records; `codex-cxc-52-2003`; `codex-cxs-95-1981` |

## 9. Validation Rules

| rule_id | Applies to | Rule | source_ids |
| --- | --- | --- | --- |
| `validate_reference_identity` | Reference flow | Fail if the product-flow UUID, Mass property UUID, unit-group UUID, 1 kg amount, species, raw state, route, presentation or net-mass qualifiers are missing or inconsistent. | `unsd-cpc-3-0`; `codex-cxs-95-1981` |
| `validate_single_route` | Process map and inventory | Fail if no preservation route is declared, more than one route is combined without separate inventories, or a route-specific input is applied unconditionally to another route. | `unsd-cpc-3-0`; `codex-cxc-52-2003` |
| `validate_mass_and_units` | Lot and normalized inventory | Fail if reference mass includes packaging, free brine or external glaze; if mass states are mixed without conversion; or if lot inputs, products and residuals lack a documented reconciliation. | `codex-cxs-95-1981` |
| `validate_route_controls` | Preservation and storage | Fail if applicable food-safety release records are absent. For frozen product, fail if the thermal centre did not reach -18 °C or colder after stabilization or storage was not maintained at -18 °C or colder. | `codex-cxc-52-2003`; `codex-cxs-95-1981` |
| `validate_allocation` | Co-products and shared resources | Fail if avoidable route aggregation remains, an allocation driver lacks records, a marketed co-product is assigned zero burden without justification, or waste conventions are undisclosed. | `eu-pef-2021-2279` |
| `validate_data_completeness` | Foreground package | Fail if required protocols omit route/site/period coverage, if material data gaps are hidden, or if any numerical temporary value is not labelled `reasoned_estimate` and disclosed as replaceable. | `eu-pef-2021-2279` |
