# Meat of horses and other equines, frozen

## 1. Scope and Applicability

This PCR governs foreground data production for frozen meat of horses and other equines within CPC 3.0 subclass 21138. It covers net conforming frozen meat released from the reporting facility and excludes fresh or chilled equine meat and edible offal as reference products. The category boundary follows `un-cpc-3-0`; the process structure follows `ec-jrc-sa-bref-2024`; foreground inventory completeness, allocation, data quality, transparency, and verification rules follow `eu-recommendation-2021-2279-pef`.

The reference quantity is 1 kg net frozen product. Equine raising and inbound transport are upstream of the foreground boundary. Outbound distribution, retail, thawing, cooking, use, and end of life are downstream. No source-derived default amount or author-estimated range is provided.

## 7. Allocation and Co-product Handling

| rule_id | Applies to | Rule | source_ids |
| --- | --- | --- | --- |
| `alloc_subdivision_first` | separable_processes | Avoid allocation first by subdividing metered operations and directly assigning stage utilities, packaging, chemicals, wastes, and emissions to the process output that causes them. | `eu-recommendation-2021-2279-pef` |

## 10. Published Dataset Profile

| Field | Value |
| --- | --- |
| dataset_role | Site-specific foreground data package for 1 kg net conforming frozen meat of horses or other equines at frozen-store release |
| downstream_use | Input to reviewed process datasets and lifecycle models that require a CPC 21138 foreground manufacturing inventory |
| allowed_use | Facility-specific gate-to-gate modelling; cradle-to-gate modelling when transparent upstream datasets are linked; comparative use only after equivalent scope, quality, allocation, and product qualifiers are confirmed |
| excluded_use | Representation of fresh or chilled equine meat, edible offal, non-equine meat, retail, cooking, consumption, or undisclosed generic industry averages |
| required_metadata | canonical PCR id; CPC code; reference UUID; species; carcass or cut form; bone state; frozen state; facility; geography; reporting period; technology; storage duration; storage condition; packaging; process inclusion; allocation; destinations |
| required_quality_disclosure | Primary-data coverage; meter allocation; mass-balance residuals; refrigerant balances; wastewater sampling; analytical methods; source records; zero evidence; data gaps; substitutions; allocation sensitivity; reviewer findings |
| update_trigger | Material change in product scope, facility technology, freezing system, refrigerant, packaging, storage condition, wastewater treatment, co-product destination, allocation relation, reporting period, or verified Tiangong identity |
