# Other aquatic invertebrates, frozen, smoked, dried, salted or in brine

## 1. Scope and Applicability

This PCR covers the foreground preservation of organisms declared as other aquatic invertebrates into a frozen, smoked, dried, salted, or brined product represented by CPC 3.0 code 21269. The Tiangong reference product flow is the exact generic CPC 21269 product flow; it does not assert a species, origin, edible status, recipe, or preservation route that the foreground data package has not declared.

The foreground boundary begins when raw or previously chilled aquatic-invertebrate material is received by the preserving facility and ends when conforming bulk or packaged product leaves that facility. Upstream capture, culture, landing, primary slaughter where relevant, and inbound transport are represented by linked upstream datasets rather than recreated in the foreground process. Distribution, retail, preparation by the user, consumption, and end-of-life are outside the default boundary.

Fish, crustaceans, molluscs, aquatic mammals, terrestrial invertebrates, and products preserved by another method are excluded. A product declared for food use applies Codex controls where relevant. A product declared non-edible, feed, bait, research, or technical grade shall remain in a non-food boundary and shall not inherit food-safety performance claims or be converted to a food product without a separately documented qualifying process and product identity.

| classification_refs | CPC 3.0 `21269`, exact scope |
| covered_products | Other aquatic invertebrates supplied frozen, smoked, dried, salted, or in brine, with organism identity, intended use, and preservation state declared |
| excluded_products | Fish; crustaceans; molluscs; aquatic mammals; terrestrial invertebrates; otherwise prepared or preserved products; undeclared mixtures whose CPC identity cannot be demonstrated |
| representative_product | One declared lot of preserved other aquatic invertebrates represented by the exact generic Tiangong CPC 21269 product flow |
| production_route | Common receiving and preparation followed by exactly one terminal route: `frozen`, `smoked`, `dried`, `salted`, or `in_brine`; the alternatives are mutually exclusive for one reference flow |
| market_state | Bulk or packaged product at the preserving-facility gate; temperature, packaging inclusion, edible or non-food status, and route-specific mass basis declared |

## 3. Reference Flow

| Field | Value |
| --- | --- |
| What | Supply of a declared frozen, smoked, dried, salted, or brined other-aquatic-invertebrate product at the preserving-facility gate |
| How much | 1 kg of conforming product on the route-specific net-mass basis below |
| How well | Product meets the declared organism identity, intended-use class, preservation route, moisture or salt condition, temperature where relevant, and acceptance specification |
| How long or cycle | One production lot at facility gate; no storage-service duration is included unless separately declared |
| reference_flow_link | One-to-one with the exact generic Tiangong CPC 21269 product flow and the selected mutually exclusive terminal route |

| Field | Value |
| --- | --- |
| Reference amount | 1 kg conforming product, excluding packaging |
| Reference product flow | Other aquatic invertebrates, frozen, smoked, dried, salted or in brine `026ea2a8-cdc9-469d-9eb5-10a7d33efab6` |
| 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 | organism or taxonomic identity; preservation route; edible, feed, bait, research, or technical intended use; product acceptance specification; net-mass method; moisture content or dry-matter basis where relevant; salt content or brine salinity where relevant; glaze fraction and deglazed mass for frozen product where applicable; drained mass and retained-brine treatment for product in brine; temperature at gate where relevant; packaging inclusion |

For frozen product, the 1 kg reference amount is deglazed net product mass and glaze water is inventoried separately. For smoked or dried product it is as-sold net product mass with moisture declared. For salted product it is as-sold net product mass with moisture and salt content declared. For product in brine it is drained product mass; supplied brine is reported separately. Another commercial mass convention may be disclosed only with measured conversion to this reference basis.

### Data Quality Requirements

| requirement_id | Applies to | Requirement | Evidence |
| --- | --- | --- | --- |
| `dq_identity` | Product and starting material | Retain organism identity at the practicable taxonomic level, lot, origin, intended-use class, preservation route, and acceptance specification; document why the generic CPC 21269 identity applies. | Supplier specification, receiving record, lot code, product specification, and CPC scope check |
| `dq_measurement` | Mass, energy, water, salt, brine, glaze, moisture, and emissions | Use calibrated measurements or traceable business records; state conversion factors, allocation drivers, test methods, and uncertainty or known gaps. | Calibration certificates, meter and invoice records, laboratory or production tests, and calculation workbook |
| `dq_temporal_coverage` | Foreground dataset | Cover a representative declared operating period, including seasonal or campaign variation where material, and disclose shutdowns, abnormal lots, and exclusions. | Production calendar, lot coverage summary, and representativeness assessment |
| `dq_completeness` | Included processes | Account for material and energy inputs, packaging, reference product, secondary outputs, wastes, wastewater, and direct emissions for the common process and selected terminal route. | Flow checklist, mass balance, utility reconciliation, and waste records |
| `dq_estimate_replacement` | `reasoned_estimate` ranges | Treat provisional ranges only as screening defaults. Replace them with representative foreground records or reviewed source evidence before active review, or document why the estimate remains, its uncertainty, and a sensitivity test. | Estimate register, replacement evidence, or documented sensitivity analysis |

## 9. Validation Rules

| --- | --- | --- | --- |
| `validation_identity` | product_identity | Confirm the canonical PCR id, CPC 3.0 code `21269`, exact generic product-flow UUID `026ea2a8-cdc9-469d-9eb5-10a7d33efab6`, Mass UUID `93a60a56-a3c8-11da-a746-0800200b9a66`, Units of mass UUID `93a60a57-a4c8-11da-a746-0800200c9a66`, and kg unit. | `unsd-cpc-3-0-21269` |
| `validation_qualifiers` | reference_flow | Reject an incomplete reference flow when preservation route, organism identity, intended-use class, net-mass method, applicable moisture or salt condition, applicable glaze or drained-mass treatment, temperature where relevant, or packaging inclusion is missing. | `codex-cxc-52-2003`; `eu-pef-2021-2279` |
| `validation_route_exclusivity` | process_inventory | Require `receiving_preparation` and exactly one terminal route. For `smoking_drying_route` select one of `smoked` or `dried`; for `salting_brining_route` select one of `salted` or `in_brine`. | `unsd-cpc-3-0-21269` |
| `validation_mass_and_inventory` | foreground_dataset | Require a route-specific reference-mass calculation, process mass balances, collection-protocol links for collected or calculated rows, upstream datasets for product inputs, and disclosure of missing flows or data. | `eu-pef-2021-2279` |
| `validation_nonfood_boundary` | intended_use | Reject a dataset that treats non-edible, feed, bait, research, or technical product as food or claims Codex food conformity without a documented qualifying process and food-product identity. | `codex-cxc-52-2003` |
| `validation_reasoned_estimates` | provisional_ranges | Flag every `reasoned_estimate`; before active review require replacement by representative records or reviewed source evidence, or a documented justification, uncertainty statement, and sensitivity analysis. |  |
