Flours, meals and pellets, inedible, of fish, crustaceans, molluscs or other aquatic invertebrates

1. Scope and Applicability

This PCR covers factory-gate production of flours, meals and pellets explicitly inedible for humans and made from fish, crustaceans, molluscs or other aquatic invertebrates. It covers products corresponding exactly to CPC 3.0 subclass 21291, including mixed-species material when its aquatic-animal composition is declared. Feed and technical destinations may be represented when the product remains explicitly non-food.

Edible fish meal, edible seafood powders, food ingredients, products made primarily from aquatic plants, fish oil as the reference product, and unspecified meal that cannot be demonstrated to be inedible are excluded. This PCR does not establish food or feed safety, legal marketability, nutritional performance, or conformity with destination-specific regulation.

The foreground boundary begins with accepted aquatic raw material at the production facility and ends with 1 kg net reference product at the factory gate. Upstream fishing, aquaculture, collection, supplier processing and inbound transport, and downstream use and end-of-life remain outside the foreground process map but shall be represented by compatible upstream or downstream datasets when required by the study scope.

reference_net_mass	Reference product	Mass 93a60a56-a3c8-11da-a746-0800200b9a66	kg	Report 1 kg net product at factory-gate release. Exclude packaging, free liquid and removable ice glaze; where material is sold glazed or in liquid, record gross and deglazed or drained mass and document the conversion.
moisture_basis	Reference product and route mass balance	Mass 93a60a56-a3c8-11da-a746-0800200b9a66	kg	Record moisture fraction, test method, sampling point and whether each mass is wet-basis or dry-matter-basis; do not mix bases within yield, allocation or mass-balance calculations.
salt_and_liquid_basis	Salted, brined, washed or marine-source material	Mass 93a60a56-a3c8-11da-a746-0800200b9a66	kg	Record added salt or salinity and free-liquid treatment when they materially affect net mass, drying demand or yield; convert all quantities to the declared net product basis.
inventory_normalization	All foreground inventory rows	Mass 93a60a56-a3c8-11da-a746-0800200b9a66	kg	Preserve measured source units, then normalize each lot or period total by conforming net reference-product output; keep electricity, fuel and water carrier units explicit before conversion.

5. System Boundary

rule_id	applies_to	rule	source_ids
boundary_foreground_operations	foreground_processes	Include receiving/preparation, exactly one conversion route, and final sizing or pelletizing through factory-gate release; include applicable utilities, packaging, rejects, wastes, co-products and direct emissions.	codex-cxc-52-2003
boundary_upstream_completeness	upstream_inputs	Do not treat upstream aquatic raw material, energy, water, packaging or transport burdens as zero merely because they are outside the foreground process map; link compatible upstream datasets and disclose exclusions and cut-offs.	eu-pef-2021-2279
boundary_non_food_identity	product_scope	Keep the reference product explicitly inedible/non-food and separate from edible fish meal or seafood powder in flow identity, dataset name, product specification and intended-use metadata.	unsd-cpc-3-0-21291
boundary_route_exclusivity	conversion_route	Select either wet_thermal_conversion or direct_drying_conversion for one product lot or dataset segment; never sum both routes for the same material. Separate and mass-weight route segments before aggregation when a facility operates both.

starting_condition_role	Foreground entry condition for facility conversion; it is not a claim of burden-free raw material
product_classification_scope	Output exactly within CPC 3.0 subclass 21291; the PCR identity remains independent of CPC
recursive_input_rule	If an input already meets this PCR product definition, record it as a same-category upstream product with its own dataset and do not recreate its upstream production inside the receiving process; disclose input and output quantities to prevent recursion and double counting
upstream_dataset_requirement	Use supplier-specific or representative datasets for aquatic raw material, electricity, fuels, water, packaging and transport required by the study; state geography, technology, time period and allocation status
disclosure	Declare source-material origin and status, selected mutually exclusive route, gate condition, applicable exclusions and cut-offs, co-product/waste classification, net-mass conversion, moisture basis, salt/brine condition, glaze/drained-mass treatment and data gaps

7. Allocation and Co-product Handling

rule_id	applies_to	rule	source_ids
allocation_subdivision_first	route_and_process_outputs	Avoid allocation by route separation, process subdivision and direct metering wherever outputs can be separately modelled. Keep the two conversion routes separate before any facility-level aggregation.	eu-pef-2021-2279
allocation_physical_then_other	unavoidable_multi_output_process	When subdivision is not possible, use a documented causal physical relationship between inputs/emissions and outputs. If no defensible physical relationship exists, use an economic or other justified relationship, disclose prices and period, and test sensitivity.	eu-pef-2021-2279
allocation_output_classification	coproduct_waste_and_internal_recycle	Classify marketable recovered oil or other usable output as a co-product, treatment-bound material as waste, and same-process recirculation as internal recycle.

calc_dry_matter	each material balance point	dry_matter_mass = measured_mass × (1 - moisture_mass_fraction); apply only when moisture is expressed as a 0-to-1 wet-basis mass fraction and preserve the test method	measured_mass; moisture_mass_fraction; basis declaration	kg dry matter
calc_normalized_exchange	each inventory exchange	normalized_amount = compatible-period exchange amount / compatible-period net conforming reference-product output	exchange amount; net output; route and period identifiers	amount per 1 kg net reference product	eu-pef-2021-2279
calc_mass_balance	each process and full foreground system	discrepancy = inputs + opening_stock - products - co-products - wastes - removed_liquids - closing_stock; calculate on both declared wet mass and dry matter when moisture changes materially	all mass inputs/outputs; stock change; moisture data	signed and percentage discrepancy with investigation note

Data Quality Requirements

requirement_id	Applies to	Requirement	Evidence
dq_identity_and_traceability	all lots	Preserve source composition, inedible/non-food status, route, product form, destination, lot links and applicable moisture/salt/glaze/drained-mass facts from receipt through release.	Lot genealogy, specifications, inspection and release records; unsd-cpc-3-0-21291; codex-cxc-52-2003
dq_measurement_basis	mass, moisture and utility data	Use calibrated equipment or documented invoice reconciliation; identify sampling and test methods, energy conversion convention, missing intervals and estimation method.	Calibration, laboratory, meter and invoice records
dq_temporal_and_operating_coverage	foreground dataset	Cover a representative production period and relevant source-material, load, route and seasonal variability; disclose shutdown, start-up, abnormal and excluded periods.	Production calendar, batch list and coverage reconciliation; eu-pef-2021-2279
