Cuttle fish and squid, frozen, smoked, dried, salted or in brine

1. Scope and Applicability

This PCR authors a narrow representative methodology for dried cephalopod products only within CPC 3.0 code 21266. It applies to edible cuttlefish or squid received at a processing site, prepared, dried by one declared drying technology, finished, and packed as a shelf-stable dried product at the factory gate.

The Tiangong product flow Dried cephalopod products is narrower than the full CPC title. This PCR does not provide methodology coverage for products preserved and marketed as frozen, smoked, salt-cured, or in brine. Salt content must be reported because salt may be naturally present or used as a formulation aid, but a preservation route whose defining operation is salting or brining is out of scope. Ice glazing and drained mass are normally not applicable to the dried route; a non-zero glaze or a product marketed in liquid is an out-of-scope signal rather than permission to apply this PCR.

The foreground boundary is processing-site gate-to-gate. Upstream capture or aquaculture, landing, primary chilling, and inbound transport remain visible through linked upstream datasets. Distribution, retail, preparation, consumption, and end-of-life are outside the foreground boundary.

3. Reference Flow

Field	Value
What	Provision of a saleable dried cuttlefish or squid product from a declared dried-product route
How much	1 kg net mass of conforming saleable product, excluding packaging
How well	Meets the producer's declared species, grade, moisture, salt-content, food-safety, and market specifications; is not frozen, smoked, salt-cured, or preserved in brine
How long or cycle	One production batch through the factory gate; no shelf-life service is credited
reference_flow_link	One kilogram of the reference product flow defined below

Field	Value
Reference amount	1 kg net conforming saleable product at factory gate, excluding packaging
Reference product flow	Dried cephalopod products ae437668-712c-407b-b8d5-7f3daf53040e
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	species or declared species group; dried preservation route; source material state at reception; declared drying technology; batch and site; net-mass basis excluding packaging; moisture content on a declared wet or dry basis and test method; salt content or salinity and test method; ice-glaze fraction declared as zero or not applicable; drained mass declared as not applicable; product grade; geographic and temporal coverage

When constructing a foreground data package, all required qualifiers must be declared in metadata, process notes, the reference-flow comment, product description, or an equivalent field. A non-zero glaze, an applicable drained-mass basis, or frozen, smoked, salt-cured, or brined market state fails this representative PCR's scope.

4. Measurement and Unit Rules

reference_net_mass	Reference product	Mass 93a60a56-a3c8-11da-a746-0800200b9a66	kg	Normalize to 1 kg net saleable dried product at factory gate; exclude packaging, pallets, non-product glaze, and free liquid.
mass_state_consistency	All cephalopod material flows	Mass 93a60a56-a3c8-11da-a746-0800200b9a66	kg	Record wet mass at the measured material state and retain moisture content and test basis so dry-matter and wet-mass balances are not mixed.
moisture_reporting	Incoming, dried-bulk, and reference-product lots	Mass fraction	kg/kg	Report moisture content with wet-basis or dry-basis designation, sampling point, method, and batch coverage; do not convert bases without showing the formula.

All ranges marked reasoned_estimate are deliberately broad candidate-stage screening guardrails, not production defaults. They apply only where the stated material state and technology condition match. Replace them with batch or site records collected under section 8, or with reviewed route-specific quantitative evidence, before this PCR can advance beyond candidate methodology.

7. Allocation and Co-product Handling

rule_id	Applies to	Rule	source_ids
allocation_subdivide_routes	All batches and route technologies	Use physical batch segregation and process subdivision first. Do not combine controlled solar/open-air and heated-air inventories or any excluded preservation route into one average unless an explicitly measured hybrid batch and energy split are documented.	eu-pef-2021-2279
allocation_rework_and_residues	Rework, residues, and co-products	Treat internal rework as an internal transfer without duplicate burden. Record waste treatment by destination. If a residue is a saleable co-product, first seek a separable process or physical relationship; document and justify any remaining allocation.	eu-pef-2021-2279
allocation_fallback	Unavoidable shared inputs or outputs	When subdivision and a defensible physical relationship cannot resolve a multifunctional process, use an economic allocation based on contemporaneous prices, disclose the price basis and period, and test sensitivity; do not apply this fallback silently.	eu-pef-2021-2279

Calculation Rules

rule_id	Applies to	Formula or rule	Inputs	Output	source_ids
calc_reference_net_mass	Reference product	Net saleable product mass equals gross packed mass minus packaging and any non-product mass. Glaze must be zero or not applicable and drained mass must be not applicable; otherwise stop and review scope.	gross packed mass; packaging mass; glaze declaration; drained-mass applicability; release status	kg net conforming saleable dried product	eu-pef-2021-2279
calc_normalize_inventory	All inventory rows	Divide the batch-attributable quantity by batch net conforming saleable product mass to report the quantity per 1 kg reference flow.	batch flow quantity; batch net saleable product mass	normalized inventory amount	eu-pef-2021-2279
calc_drying_water_loss	Drying water balance	Water removed equals feed wet mass multiplied by feed moisture fraction minus dried-output wet mass multiplied by output moisture fraction, after aligning both moisture results to wet basis and accounting separately for sampled rejects or transfers.	feed mass and moisture; dried-output mass and moisture; reject and transfer masses and moisture	kg calculated water removed
calc_process_mass_balance	Each foreground process	Reconcile measured input mass with product, waste, transfer, retained-stock change, and calculated water outputs; investigate rather than force-close material discrepancies.	all batch mass records; stock change; moisture results	documented process mass-balance residual
calc_route_energy	Drying energy	Report electricity and each thermal carrier separately. Convert fuel with a disclosed calorific basis and never add delivered heat produced from the same counted fuel.	electricity meters; fuel records; calorific value; purchased heat; hybrid split	kWh and MJ per kg reference product by carrier	eu-pef-2021-2279

Data Quality Requirements

requirement_id	Applies to	Requirement	Evidence
dq_scope_identity	Product and batch identity	Demonstrate that the product is a dried cuttlefish or squid product and not a frozen, smoked, salt-cured, or brine-preserved product; retain all required reference-flow qualifiers.	product specification; label; batch release; route declaration; unsd-cpc-3-0-21266
dq_route_separation	Drying technology	Keep controlled solar/open-air, heated-air, and measured hybrid batches distinguishable; disclose any hybrid split and exclude route averages that mix incompatible technologies.	route logs; energy records; batch genealogy
dq_measurement	Mass, moisture, salt, temperature, and utilities	Use calibrated instruments or documented methods at the declared sampling point and retain units, moisture basis, detection limits where relevant, and conversion formulas.	calibration certificates; laboratory reports; meter records; codex-cxc-52-2003
dq_temporal_coverage	Foreground averages	Prefer 12 consecutive months; if seasonal production or a shorter campaign is represented, cover the full campaign and disclose omitted periods, atypical downtime, and production weighting.	production calendar; batch register; coverage calculation
dq_completeness	Foreground inventory	Reconcile product, residue, wastewater, water, and energy records; disclose missing flows, cut-offs, substitutions, and mass-balance residuals rather than replacing them silently.	reconciliation workbook; data-gap register; eu-pef-2021-2279
dq_estimate_replacement	All reasoned_estimate ranges	Treat reasoned estimates only as candidate screening guardrails. Replace each used estimate with protocol-based foreground records or reviewed route-specific evidence before methodology activation or dataset release for normal use.	record-to-range replacement log; reviewer decision; cited replacement source

9. Validation Rules

rule_id	Applies to	Rule	source_ids
validation_scope	Product applicability	Confirm the output is dried cuttlefish or squid and that frozen, smoked, salt-cured, and brine-preserved market routes are absent; non-zero glaze or applicable drained mass fails scope.	unsd-cpc-3-0-21266
validation_reference_flow	Quantitative reference	Confirm exactly 1 kg net conforming saleable output uses product-flow UUID ae437668-712c-407b-b8d5-7f3daf53040e, Mass UUID 93a60a56-a3c8-11da-a746-0800200b9a66, Units of mass UUID 93a60a57-a4c8-11da-a746-0800200c9a66, and kg, with every required qualifier declared.	eu-pef-2021-2279
validation_route_exclusivity	Drying process	Confirm one technology route per batch. A controlled solar/open-air and heated-air combination is allowed only as an explicitly documented hybrid with measured energy split; never average an excluded preservation route into the dataset.
validation_mass_and_quality	Process and product records	Reconcile received, prepared, dried-bulk, saleable, reject, residue, wastewater, stock-change, and calculated moisture-loss records; verify moisture and salt bases and explain material residuals.	codex-cxc-52-2003
validation_energy	Drying utilities	Confirm electricity and each thermal carrier are separately reported, conversions are disclosed, and fuel is not double counted with heat produced from that fuel.	eu-pef-2021-2279
validation_estimates	Candidate quantitative screening	Flag every value that still relies on reasoned_estimate; such a value is provisional and cannot satisfy normal-use release until replaced by collected records or reviewed route-specific evidence.
validation_sources_and_destinations	Upstream and waste links	Confirm every material input, energy carrier, packaging input, wastewater, residue, reject, and other waste has an identified source or destination dataset and that substitutions and allocation are disclosed.	eu-pef-2021-2279

10. Published Dataset Profile

Field	Value
dataset_role	Foreground production data package for one declared dried cephalopod product and drying technology
downstream_use	May be published as a secondary_dataset or background_dataset after review, complete upstream linking, and replacement of relied-upon reasoned estimates
allowed_use	Factory-gate modelling of dried cuttlefish or squid products matching the declared species group, source-material state, drying technology, moisture, salt, net-mass, geography, and time period
excluded_use	Frozen, smoked, salt-cured, or brine-preserved products; liquid-packed products; products with non-zero glaze; mixed seafood without separable records; generic representation of all CPC 21266 routes
required_metadata	PCR id; product-flow UUID; species group; origin and capture or aquaculture status; site; period; source-material state; drying technology and hybrid split if any; net-mass basis; moisture content and basis; salt content; glaze declaration; drained-mass applicability; grade; allocation; upstream datasets; waste destinations
required_quality_disclosure	Data coverage; instrument and method evidence; batch weighting; mass and energy reconciliation; cut-offs; substitutions; allocation; reasoned-estimate replacement status; route exclusions; uncertainty and data gaps
update_trigger	Change in species mix, raw-material state, drying technology or energy carrier, product moisture or salt specification, packaging, site, allocation, upstream dataset, regulation, or reviewed evidence; any observed value outside a screening guardrail also triggers review rather than automatic rejection
