# Groundnuts, shelled

## 1. Scope and Applicability

This PCR covers shelled groundnuts (peanut kernels) represented by the exact generic CPC 3.0 product category 21421, after commercial shelling and associated cleaning, sizing, sorting, lot-control, and gate preparation. It supports raw or dried kernels sold in bulk or packages and does not itself assert a food grade, moisture class, kernel size, aflatoxin result, intended use, or packaging format.

The PCR excludes groundnuts in shell, seed for planting, roasted or otherwise cooked peanuts, peanut oil, flour, meal, paste, butter, confectionery, and downstream transport, retail, use, or end-of-life. A dataset may claim conformity with Codex CXS 200-1995 only where the declared intended use and product state fall within that standard and its applicable quality requirements are demonstrated. The exact generic Tiangong product flow is retained for every route; route and quality differences are expressed only through required qualifiers.

The foreground boundary begins with accepted in-shell groundnuts at the shelling-facility receiving gate and ends with the net mass of shelled groundnuts ready to leave the facility gate. A producer starting from already shelled kernels shall declare that starting condition and exclude shelling burdens only with an upstream dataset that preserves the omitted shelling route and product state.

| classification_refs | CPC 3.0: 21421, Groundnuts, shelled |
| covered_products | Raw or dried kernels of Arachis hypogaea L. after removal of the pod, whether whole, split, broken, sized, graded, bulk, or packaged, provided the product remains shelled groundnuts rather than a further manufactured peanut product. |
| excluded_products | Groundnuts in shell; seed for planting; roasted or otherwise cooked peanuts; peanut oil, flour, meal, paste, butter, confectionery, and mixed or formulated foods. |
| representative_product | Generic shelled groundnuts at the shelling-facility gate, with actual lot moisture, grade, aflatoxin-control status, net-mass basis, and packaging state declared. |
| production_route | Receipt and pre-cleaning of in-shell groundnuts; mechanical or manual shelling and size grading; sorting, sampling/testing and lot disposition; net weighing, optional packaging, and dispatch preparation. Alternative shell and rejected-material dispositions are mutually exclusive. |
| market_state | Bulk or packaged shelled kernels at facility gate; raw or dried state, intended use, moisture basis, grade, and packaging are qualifiers rather than separate reference flows. |

## 3. Reference Flow

| Field | Value |
| --- | --- |
| What | Shelled groundnuts supplied at the shelling-facility gate for the declared intended use. |
| How much | 1 kg net mass of shelled groundnuts. |
| How well | At the declared shelling route, raw/dried state, moisture content and basis, grade or kernel-size class, rejected-material rule, aflatoxin-control status and limit basis, and packaging state. |
| How long or cycle | One declared production lot at facility-gate handover; storage duration included before handover is reported. |
| reference_flow_link | The functional unit is realized by exactly 1 kg of the generic Tiangong product flow `66ce8a77-8fe1-4513-910c-741aebeec043`, normalized on net mass as received unless a separately reported dry-matter result is required. |

| Field | Value |

| Reference amount | 1 kg net mass |
| Reference product flow | Groundnuts, shelled `66ce8a77-8fe1-4513-910c-741aebeec043` |
| Reference flow property | Mass `93a60a56-a3c8-11da-a746-0800200b9a66` |

When constructing a foreground data package, every item in `Required qualifiers` shall be declared in dataset metadata, process notes, the reference-flow comment, the product description, or an equivalent field. A missing qualifier makes the reference-flow definition incomplete for that package.

## 4. Measurement and Unit Rules

| rule_id | Applies to | Required property | Required unit | Rule |
| --- | --- | --- | --- | --- |
| `reference_net_mass` | Final shelled groundnuts | Mass `93a60a56-a3c8-11da-a746-0800200b9a66` | kg | Determine net mass as calibrated gross mass minus packaging or container tare. Normalize all inventory results to 1 kg net shelled-groundnut output at the declared moisture basis. |
| `moisture_as_received` | In-shell input, intermediate kernels, and final shelled groundnuts | Mass fraction and Mass `93a60a56-a3c8-11da-a746-0800200b9a66` | % and kg | Record moisture content, sampling time, test method, and whether mass is as received or moisture-corrected. Do not mix wet-basis and dry-matter masses. |
| `codex_kernel_moisture` | Lots claiming the CXS 200-1995 intended-use scope | Mass fraction | % | For peanut kernels intended for processing for direct human consumption under CXS 200-1995, verify the specified maximum moisture content of 9.0%; a stricter destination requirement remains controlling and shall be disclosed. |
| `internal_mass_consistency` | Each lot and process | Mass `93a60a56-a3c8-11da-a746-0800200b9a66` | kg | Use one consistent as-received basis for input kernels, accepted kernels, shells, rejects, dust or fines, samples, inventory change, and final net output; report any separately calculated dry-matter balance. |
| `aflatoxin_result_basis` | Aflatoxin-control records | Concentration and lot decision | declared test unit | Record the sampled lot, sampling plan, analytical method, result, reporting limit, applicable legal or contractual limit, intended use, and accept/reject/divert decision.

## 5. System Boundary

### Boundary Abstraction

| Field | Value |
| --- | --- |
| declared_starting_condition | Accepted in-shell groundnuts at the shelling-facility receiving gate; an already-shelled starting input is allowed only when explicitly declared as an alternative route. |
| starting_condition_role | Foreground entry condition for a gate-to-gate shelling dataset; cultivation, harvest, curing, and delivery burdens are represented through upstream datasets or separately linked transport. |
| product_classification_scope | Exact generic shelled-groundnut product category; quality, intended-use, moisture, grade, aflatoxin-control and packaging differences remain qualifiers. |
| recursive_input_rule | If shelled groundnuts enter for re-cleaning, regrading, or repacking, record them once as a same-category input with a separate upstream dataset and do not recreate their earlier shelling operations inside this foreground package. |
| upstream_dataset_requirement | Link representative upstream datasets for in-shell groundnuts, electricity, packaging, transport not already included by suppliers, and treatment of exported wastes or residues. Preserve geography, technology, moisture, and temporal applicability. |
| disclosure | Declare starting product state, supplier-gate versus delivered-gate convention, shelling technology, moisture and grade, lot-control route, all excluded operations, storage duration, and whether packaging and outbound loading are included. |

| `boundary_upstream_links` | Product and energy inputs | Keep cultivation, harvest, curing, external inbound transport, electricity generation, packaging manufacture, and external treatment outside the foreground process only when linked through representative upstream or downstream datasets; disclose every cut-off and justify its environmental insignificance. | `eu-pef-2021-2279` |
| `boundary_route_preservation` | Alternative starting conditions | Do not model in-shell receipt and already-shelled receipt as simultaneous inputs. Select one route for each lot and preserve the omitted shelling history through its upstream dataset and route qualifier. | `unsd-cpc-3-0-2025`; `eu-pef-2021-2279` |
| `boundary_controlled_material` | Rejected kernels, shells, dust, samples, and packaging rejects | Include the measured mass and documented disposition of every controlled material stream. A stream recorded as a saleable co-product shall not also be recorded as waste, and a rejected food lot shall not be credited as feed or product without evidence that the selected disposition is lawful and meets its acceptance specification. | `codex-cxc-22-1979`; `codex-cxc-55-2004-2025`; `eu-pef-2021-2279` |

## 7. Allocation and Co-product Handling

| rule_id | Applies to | Rule | source_ids |
| --- | --- | --- | --- |
| `allocation_avoid_first` | Multi-output foreground operations | Avoid allocation by subdividing separately measured operations or by expanding the system only where the substituted function and dataset are explicitly justified. Do not create an avoided-product credit solely from a waste-disposal claim. | `eu-pef-2021-2279` |
| `allocation_shell_route` | Groundnut shells | Treat shells as waste when they have no documented product function and model their treatment without co-product allocation. When shells are sold or transferred as a specified co-product, record only that measured portion as product and apply the PEF hierarchy to any shared burdens. | `eu-pef-2021-2279` |
| `allocation_shared_burdens` | Shared burdens remaining after subdivision | Use a physical relationship only where it reflects the underlying causal relationship between inputs, outputs and functions; otherwise use economic allocation with contemporaneous, geographically and temporally representative prices. Report the method, factors, price basis and sensitivity. | `eu-pef-2021-2279` |
| `allocation_rejected_material` | Rejected kernels and controlled material | Assign no co-product credit to material rejected for the declared use unless a lawful alternative specification, analytical release where required, recipient and function are documented. Product diversion and waste treatment are mutually exclusive for each measured portion. | `codex-cxc-22-1979`; `codex-cxc-55-2004-2025`; `eu-pef-2021-2279` |
| `allocation_mass_balance` | All lot outputs | Preserve the unallocated physical mass balance separately from burden allocation: input mass equals accepted kernels plus shells, rejected material, dust/fines, samples, inventory change and measured losses on one moisture basis. Allocation shall not alter these physical quantities. | `eu-pef-2021-2279` |
