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.

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.

Calculation Rules

rule_id	Applies to	Formula or rule	Inputs	Output	source_ids
calc_reference_mass	Reference output	Frozen net mass = gross frozen mass minus measured glaze mass; brined net mass = measured drained product mass; other routes use as-sold product mass excluding packaging, with moisture and salt basis declared.	gross_product_mass; glaze_mass; drained_mass; packaging_mass; moisture; product_salt	conforming_reference_mass_kg	codex-cxc-52-2003
calc_normalization	All inventory rows	normalized quantity = period or lot quantity divided by conforming reference product mass in kg.	inventory_quantity; conforming_reference_mass_kg	quantity_per_kg_reference_product	eu-pef-2021-2279
calc_mass_balance	Each included process	Reconcile measured material inputs with product, co-product, waste, retained brine or glaze, and quantified mass transfer or loss; investigate and disclose material imbalance.	input_masses; product_masses; waste_masses; retained_or_removed_water; measured_losses	process_mass_balance	eu-pef-2021-2279
calc_route_selection	Process map	Set exactly one terminal route flag true for each reference flow and exclude inventories from all non-selected route processes.	preservation_route; route_mode	selected_route_inventory	unsd-cpc-3-0-21269

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

rule_id	applies_to	rule	source_ids
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.
