Fish, dried but not smoked; salted but not dried or smoked; or in brine

1. Scope and Applicability

This PCR applies to edible fish products placed on the market in one of three declared preservation states: dried but not smoked; salted but neither dried nor smoked; or held in brine. It covers receiving eligible fresh or frozen fish, route-specific thawing and preparation, salting or brining where used, non-smoking drying where used, sorting, packing, and the storage operations needed to deliver the declared product state. Upstream fishing or aquaculture, feed production, hatchery operations, vessel operations, and transport to the declared processing gate are represented by linked upstream datasets rather than recreated inside the foreground boundary.

The PCR excludes smoked and smoke-dried fish, edible fish meal, fish offal sold as a distinct product category, canned or cooked fish, caviar, crustaceans, molluscs, and products whose preservation identity is primarily freezing or another preparation not named above. Product-specific food-safety, additive, contaminant, labelling, parasite-control, and legal requirements remain mandatory and must be declared for the species, origin, route, and market jurisdiction.

reference_net_mass	Reference product	Mass 93a60a56-a3c8-11da-a746-0800200b9a66	kg	Report exactly 1 kg of conforming edible product excluding packaging; for brined products declare whether the commercial net quantity includes brine and also collect drained fish mass when relevant to the declared specification.

5. System Boundary

Boundary Abstraction

Field	Value
declared_starting_condition	Eligible fresh, chilled, or frozen edible fish is received at the processing facility with measured mass, species/product form, origin, preservation state, temperature condition, supplier lot identity, and acceptance disposition.
starting_condition_role	The received fish is a technosphere product input; fishing or aquaculture and delivery to the gate are upstream and linked through representative datasets.
product_classification_scope	The foreground output is limited to CPC 3.0 code 21231 product states; smoking and other prepared-fish identities are outside this PCR.
recursive_input_rule	A purchased input already in the same CPC 21231 category is recorded once as an upstream product input with its declared preservation route and is not recursively reprocessed unless the foreground facility performs a documented transformation.
upstream_dataset_requirement	Link representative upstream datasets for received fish, salt, water, energy, packaging, refrigerants, transport, and waste treatment at the geographic, technological, and temporal resolution available.
disclosure	Declare species, origin, input state, route steps, salting/brining method, drying technology and endpoint claim, storage regime, packaging, co-products, waste treatment, allocation, exclusions, and any data gaps.

rule_id	Applies to	Rule	source_ids
boundary_route_gate	Foreground process system	Include every operation performed from accepted fish receipt through production of the packed reference product at the facility gate, including conditional thawing, preparation, salting/brining, drying, intermediate storage, packaging, refrigeration, sanitation-related material use when attributable, rejects, wastewater/brine, and waste handling.	codex-cxc-52-2003
boundary_upstream_linking	Purchased fish and other technosphere inputs	Represent production and delivery before the declared receiving gate with linked upstream datasets and disclose missing or proxy geography, technology, and time.	eu-pef-2021-2279
boundary_route_exclusion	Smoking and out-of-scope preparation	Do not include smoking or smoke-drying under this PCR; a dataset performing those operations requires the applicable product category rule.	unsd-cpc-3-0-2025
boundary_food_safety_controls	All foreground steps	Model the actual process sequence and retain the HACCP/prerequisite-programme records that establish relevant hazards, critical or operational limits, monitoring, corrective actions, verification, and lot release.	codex-cxc-52-2003

allocation_avoid_first	Shared or multi-output foreground operations	First avoid allocation through process subdivision or by expanding the system where the substituted function is demonstrable and consistent with the study goal.	eu-pef-2021-2279
allocation_physical_second	Unavoidable joint processes with a causal physical relationship	Allocate by a measured causal physical relationship such as mass, processing time, occupied capacity-time, or metered energy; explain why the driver represents resource use or emissions.	eu-pef-2021-2279
