# Uncooked pasta, not stuffed or otherwise prepared

## 1. Scope and Applicability

This PCR covers factory production of uncooked, unfilled pasta and noodle products that are not otherwise prepared and fall within CPC 3.0 code 23710. Covered products may be dry, semi-dried, or another declared uncooked moisture state and may use wheat, rice, other cereals, pulses, or mixtures as the principal farinaceous material. The foreground data package shall describe the actual formulation, forming route, conditioning state, packaging state, and reporting gate.

Filled pasta, cooked or pre-cooked pasta, seasoned or otherwise prepared products, complete dishes, sauces, and products whose principal delivered function is not an uncooked pasta product are excluded. Ingredient production, consumer cooking, distribution, and end-of-life are not part of the default foreground manufacturing dataset, but may be connected as upstream or downstream datasets in a lifecycle model.

The Tiangong flow `540fef24-1038-48b8-8ee1-8cc415df780a` is a verified product flow for **semi-dried noodles** and is used only as the representative product form for this category. It is not a generic UUID for every CPC 23710 product. A data author shall declare the actual product form and shall replace the representative UUID when a more specific real Tiangong flow matches that product. The representative UUID must never be silently assigned to dry pasta, fresh uncooked pasta, egg pasta, rice noodles, or another materially different form.

## 2. Product Category Identity

| Field | Value |
| --- | --- |
| canonical_pcr_id | pcr.food-products-beverages-and-tobacco-textiles-apparel-and-leather-products.grain-mill-products-starches-and-starch-products-other-food-products.uncooked-pasta-not-stuffed-or-otherwise-prepared |
| classification_refs | CPC 3.0: 23710 — Uncooked pasta, not stuffed or otherwise prepared |
| covered_products | Uncooked and unfilled pasta or noodles delivered without other preparation; dry, semi-dried, fresh-uncooked, or another explicitly declared moisture state; wheat-, rice-, other cereal-, pulse-, or mixed-material formulations |
| excluded_products | Filled pasta; cooked or pre-cooked pasta; seasoned or otherwise prepared pasta; complete dishes; sauces; couscous or another product classified outside CPC 23710 |
| representative_product | Semi-dried noodles are the representative product/physical form because the verified Tiangong reference flow is specific to that form; the category remains broader than the representative flow |
| production_route | Ingredient receipt and preparation; dough or batter preparation; forming by extrusion, sheeting, cutting, or another declared method; product-specific conditioning or drying; inspection; and packaging or bulk release |
| market_state | Uncooked product at the declared factory-gate release condition, with moisture/conditioning and packaging state explicitly reported |

## 3. Reference Flow

| Field | Value |
| --- | --- |
| What | Uncooked, unfilled, and not otherwise prepared pasta or noodles at the declared factory-gate release condition |
| How much | 1 kg net product mass, excluding packaging |
| How well | Conforming to the producer's release specification and applicable legal or customer requirements for the declared product form, formulation, moisture/conditioning state, and packaging state |
| How long or cycle | One production campaign or reporting period sufficient to represent the declared product until the factory-gate hand-off; shelf life is reported as metadata and does not change the 1 kg reference amount |
| reference_flow_link | One kilogram of the declared saleable uncooked pasta output; use the representative semi-dried-noodles UUID only when that identity is accurate, otherwise select a more specific real product flow |

| Field | Value |
| --- | --- |
| Reference amount | 1 kg net uncooked pasta product |
| Reference product flow | semi-dried noodles `540fef24-1038-48b8-8ee1-8cc415df780a` — representative only; replace for a more specific actual product form |
| 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 | actual product form and Tiangong product-flow identity; principal farinaceous material; formulation and egg/non-egg status; forming technology; moisture or conditioning state at release; packaging or bulk state; production geography and facility/route; factory-gate reporting point |

When constructing a foreground data package, every item listed in `Required qualifiers` shall be declared in dataset metadata, process notes, the reference-flow comment, the product description, or an equivalent field. Missing qualifiers make the reference-flow definition incomplete. If the declared form is not semi-dried noodles, retaining UUID `540fef24-1038-48b8-8ee1-8cc415df780a` without an explicit documented identity match is a validation error.

## 4. Measurement and Unit Rules

| rule_id | Applies to | Required property | Required unit | Rule |
| --- | --- | --- | --- | --- |
| `reference_mass` | Reference product and mass-normalized product/intermediate rows | Mass `93a60a56-a3c8-11da-a746-0800200b9a66` | kg | Report the reference product as net product mass. Packaging mass is inventoried separately and is never included in the 1 kg reference amount. |
| `mass_conversion` | Ingredient, intermediate, product, waste, and moisture-balance mass records | Mass `93a60a56-a3c8-11da-a746-0800200b9a66` | kg | Convert source records to kg using documented unit conversions before normalization; retain original units and conversion evidence. |
| `conditioning_state` | Product and intermediate mass values | Mass `93a60a56-a3c8-11da-a746-0800200b9a66` | kg | Record the measurement point and product moisture/conditioning state. Do not compare or combine masses measured at materially different conditioning states without a documented moisture correction. |
| `energy_units` | Electricity and thermal-energy inputs | Energy appropriate to the selected flow | kWh for electricity; MJ for fuel or delivered thermal energy | Keep electricity and thermal energy as separate records and document any calorific-value or steam/heat conversion used. |

## 5. System Boundary

### Boundary Abstraction

| Field | Value |
| --- | --- |
| declared_starting_condition | Accepted farinaceous ingredients, water, other formulation ingredients, utilities, and packaging materials at the manufacturing-site receipt point, together with the declared formulation, product form, and initial moisture state |
| starting_condition_role | Foreground manufacturing input gate; upstream production burdens are supplied by separate traceable datasets rather than recreated inside the pasta manufacturing process |
| product_classification_scope | CPC 3.0 code 23710 across declared uncooked and unfilled product forms; the semi-dried-noodles flow is representative, not category-wide identity authority |
| recursive_input_rule | Purchased uncooked pasta or noodle material from the same category that enters reprocessing shall be recorded once as a technosphere product input with its own upstream dataset and declared state; do not recursively reconstruct its manufacturing inside this foreground dataset |
| upstream_dataset_requirement | Each material ingredient, utility, and packaging input shall link to a geographically, technologically, and temporally representative upstream dataset or be disclosed as a data gap |
| disclosure | Declare product form, formulation, moisture/conditioning state, forming and conditioning technologies, packaging state, reporting gate, included sites, allocation method, data period, and any omitted or unresolved flows |

| rule_id | Applies to | Rule | source_ids |
| --- | --- | --- | --- |

| `boundary_dry_route` | Dry or semi-dried routes | Include the actual conditioning/drying operation, electricity, thermal energy or fuel, water or moisture removal, losses, and the declared released moisture state. Apply dry-pasta source rules only to a route that is demonstrably within their dry-pasta scope. | `unafpa-dry-pasta-pefcr-2020` |
| `boundary_upstream_connections` | Ingredient, utility, and packaging production | Represent upstream production and inbound services through separate datasets linked to the collected foreground bill of materials; do not treat an unverified generic proxy as product-specific data. | `unafpa-dry-pasta-pefcr-2020` |
| `boundary_downstream_exclusion` | Default foreground product dataset | Exclude distribution, consumer storage/cooking, packaging end-of-life, and food end-of-life from this factory-gate foreground dataset. Add them only in an explicitly declared downstream lifecycle model. |  |
| `boundary_recursive_category_input` | Same-category purchased pasta or noodle input | Record the purchased product at its actual entry state with a distinct upstream dataset and do not expand the same category recursively within the foreground process. |  |

An annual dry-pasta dataset shall cover 12 consecutive months; another product form may use a representative campaign or seasonal period only with justification and production-volume coverage disclosure. | Dated meter, batch, production, inventory, and waste records; coverage calculation; justification |
| `dq_measurement_traceability` | Mass, moisture, water, electricity, and thermal-energy records | Preserve original readings, units, meter/scale identity, calibration or verification status, conversions, and responsible record source. | Calibration certificates, meter logs, laboratory method records, invoices, and conversion worksheet |
| `dq_mass_balance` | Both foreground processes | Reconcile material inputs with intermediate/product outputs, measured waste, moisture release where relevant, inventory change, and documented internal return. Investigate and disclose unexplained imbalance; do not force closure with an undocumented default. | Campaign mass-balance worksheet and variance investigation |
| `dq_completeness` | Foreground inventory | Include all material ingredient, water, energy, packaging, product, and waste flows that cross the declared foreground boundary. Record not-applicable decisions and unresolved UUIDs explicitly. | Completeness checklist tied to process map, BoM, utilities, waste register, and packaging records |
| `dq_background_linkage` | Upstream datasets | Match upstream datasets to actual ingredient, energy, water, packaging, and waste-treatment identities and disclose geographic, temporal, or technological proxies. | Dataset references, supplier/origin records, proxy rationale, and data-gap register |
| `dq_source_scope` | Use of external dry-pasta evidence | Apply `unafpa-dry-pasta-pefcr-2020` only to dry-pasta rules that fit the declared route. Use it as process/data-collection guidance, not as proof that a semi-dried, fresh, rice-, pulse-, or other broader CPC 23710 product conforms to that PEFCR. | Product-scope comparison and methodology limitation statement |

## 9. Validation Rules

| rule_id | Applies to | Rule | source_ids |
| --- | --- | --- | --- |
| `validate_category_and_form` | Product identity | Confirm CPC 3.0 code 23710, uncooked state, absence of filling, and absence of other preparation; reject out-of-scope cooked, filled, seasoned/prepared, or complete-dish products. | `international-epd-pcr-2010-01` |
| `validate_representative_flow_use` | Reference product flow | Confirm actual product form against the full Tiangong flow record. If the product is not semi-dried noodles or a more specific matching real flow exists, UUID `540fef24-1038-48b8-8ee1-8cc415df780a` shall be replaced; silent reuse is an error. |  |
| `validate_reference_support_chain` | Reference amount and unit | Confirm reference amount 1 kg net product, Mass UUID `93a60a56-a3c8-11da-a746-0800200b9a66`, Units of mass UUID `93a60a57-a4c8-11da-a746-0800200c9a66`, and reference unit kg; packaging mass shall remain separate. |  |
| `validate_process_coverage` | Foreground process map | Confirm that actual formulation, forming, conditioning/drying, inspection/rework accounting, and packaging or bulk release are represented and that non-applicable route steps are explicitly justified. | `unafpa-dry-pasta-pefcr-2020` |
| `validate_inventory_and_mass_balance` | Foreground inventory | Confirm collected ingredient/packaging BoM, energy, water, output, loss, and waste records; reconcile mass by process and product state without undocumented default values. | `unafpa-dry-pasta-pefcr-2020` |
| `validate_allocation` | Shared operations and multi-output processes | Confirm subdivision was attempted first and any remaining allocation has a physically representative driver, complete denominator, same-period records, and disclosure. | `unafpa-dry-pasta-pefcr-2020` |
| `validate_period_and_traceability` | Dataset quality | Confirm period alignment, site/line scope, calibration/conversion evidence, source traceability, upstream dataset linkage, and explicit data gaps. | `unafpa-dry-pasta-pefcr-2020` |

## 10. Published Dataset Profile

| Field | Value |
| --- | --- |
| dataset_role | Foreground product-production dataset for one declared uncooked pasta form and factory-gate release condition |
| downstream_use | May be published as a `secondary_dataset` or `background_dataset` after methodology review, UUID completion, validation, and release controls |
| allowed_use | Product systems whose product form, formulation, forming/conditioning route, moisture state, packaging state, geography, technology, and reporting gate are compatible with the declared dataset |
| excluded_use | Silent use of the semi-dried-noodles UUID for another product form; cooked, filled, seasoned/prepared, or complete-dish products; use as a cradle-to-grave result without explicit downstream stages; unsupported cross-form or cross-route averages |
| required_metadata | Canonical PCR id; CPC; actual Tiangong product-flow UUID; all required qualifiers; site/geography; technology and process map; reporting period and gate; net product and packaging basis; allocation; source and proxy disclosures; unresolved-flow status |
| required_quality_disclosure | Record coverage, calibration/conversion evidence, mass-balance result, allocation rationale, temporal/geographic/technological representativeness, dry-pasta-source applicability, missing UUIDs, proxy datasets, and validation findings |
| update_trigger | Change in product form or flow identity, formulation, egg status, principal material, forming or conditioning technology, released moisture state, packaging configuration, site/energy supply, allocation basis, reporting gate, material supplier mix, legal specification, or evidence source |
