Other soil machinery, n.e.c.

1. Scope and Applicability

This PCR applies to complete agricultural, horticultural or forestry machinery for soil preparation or cultivation, and lawn or sports-ground rollers, that belongs to the residual CPC 44119 subclass and is not separately classified in CPC 44111 through 44115. It covers manufacture from purchased materials and components through fabrication, joining, surface coating when performed, final assembly, factory testing and release of the finished machinery at the factory gate.

The category excludes ploughs; harrows, scarifiers, cultivators, weeders and hoes; seeders, planters and transplanters; manure spreaders and fertilizer distributors; parts sold separately; self-propelled earth-moving machinery; tractors; use, maintenance and end-of-life. A product must not be assigned here merely because its commercial name contains “soil machinery”; the producer shall document why no more specific soil-machinery subclass applies. The process pattern is for complete machinery manufacture and does not represent the manufacture of replacement parts as the reference product.

The bounded representative configuration used to make the minimum component schedule actionable is a non-self-propelled 24-inch by 36-inch steel tow lawn roller of the Agri-Fab 45-01791 type. The manufacturer manual identifies a welded-steel roller drum, scraper bar, two hitch tubes, two hitch brackets, two replaceable plastic bearings, washers, three bolt sizes, lock nuts, a fill plug, cotter pins, a hitch pin and a hair cotter pin. This configuration is a completeness case, not a narrowing of CPC 44119 and not a category-average bill of materials. A different CPC 44119 machine shall retain the residual-classification test and replace the representative schedule with its own model-specific atomic component rows.

The following component rows implement the complete Agri-Fab 45-01791-type representative schedule. The manual counts are completeness checks, not normalized amounts: record the measured mass of each exact part family for the declared model. For a part made inside the foreground, record its material and process burdens plus an internal transfer, and do not also count it as a purchased component. For a different CPC 44119 machine, replace this schedule with an equally explicit model-specific schedule while preserving the residual classification test.

7. Allocation and Co-product Handling

rule_id	Applies to	Rule	source_ids
allocation_subdivision	foreground_burden_allocation	Avoid allocation by metering fabrication, coating, assembly, testing and treatment operations separately for the declared product family wherever practicable.
allocation_shared_operations	foreground_burden_allocation	When shared operations cannot be subdivided, allocate measured burdens using the causal driver recorded for that operation, such as machine time, coated area, weld length or measured energy; use mass only when no more causal record exists and disclose the sensitivity.
allocation_scrap	foreground_burden_allocation	Report scrap and other waste at the point it leaves the foreground. Do not subtract an avoided virgin-material burden inside the manufacturing inventory; identify the chosen recycling or treatment modelling convention separately so downstream models can avoid double counting.
allocation_rework	foreground_burden_allocation	Assign rework and rejected-part burdens to the conforming output of the same production period unless the rejected material leaves as a separately modelled co-product; disclose any alternative treatment.

For supplied shielding carbon dioxide and coating constituents that remain the same substance, use an unchanged-species loss balance only when every input, return, recovery, retention, captured output, destruction term and stock change is documented. For carbon dioxide formed by fuel combustion, use the separate combustion-carbon calculation and never treat reacted fuel as destroyed pollutant. Split fossil and biogenic carbon, keep fabrication heat, coating-oven and factory-test sources separate, and do not mix release compartments.	kg	Each compliance test, gas issue or representative campaign; continuous data aggregated monthly	Representative operating modes across the production year	Every included release point and fugitive source	Sum post-control releases by substance, origin, source and actual compartment, then divide by net kg conforming product.

A site-made component is not also a purchased input.	upstream transfer; downstream receipt; opening and closing WIP or in-transit stock; exact transfer loss	reconciled internal movement and disclosed gap
calc_waste_generation	Each exact waste identity	Waste generated = outbound waste + closing dedicated waste stock − opening dedicated waste stock + documented internal recovery from that waste stock. Exported waste = outbound waste only. Do not enter exported waste a second time as generation.	outbound transfer; opening and closing waste stock; internal recovery	generated waste and separately disclosed exported waste
calc_shared_operation_allocation	Shared fabrication, coating, assembly or testing	Allocate the reconciled shared amount by the documented causal driver for the same period; the shares shall sum to one.	shared amount; product-specific causal-driver totals	product-specific exchange amount

Apply by substance, fossil or biogenic origin and actual compartment. Do not apply this loss balance to fuel combustion, because combustion forms carbon dioxide from fuel carbon. Do not use the balance if any material term is unmeasured.	supplied substance; opening and closing usable stock; origin; retained amount; returned or recovered amount; captured amount; documented control destruction; compartment	unchanged post-control substance mass by origin and compartment	us-epa-ap42-electric-arc-welding-1995; us-epa-misc-metal-surface-coating-tsd-2001
calc_combustion_carbon_dioxide	Carbon dioxide formed by fabrication heat, coating-oven and factory-test fuel combustion	Prefer a validated direct carbon-dioxide measurement. Otherwise, for each source and carbon origin, formed carbon dioxide = consumed fuel mass × verified fuel carbon mass fraction × verified fossil or biogenic origin fraction × documented oxidation fraction × 44/12. When fuel is recorded by volume, convert it to mass only with a measured or supplier-specific density at stated reference conditions. As an alternative to an oxidation fraction, subtract carbon measured in carbon monoxide, methane, soot or ash, product retention and other documented unoxidized destinations from consumed fuel carbon before multiplying by 44/12; never use both adjustments for the same carbon, subtract reacted fuel as destroyed pollution, or count the formed carbon dioxide in another balance.

9. Validation Rules

validation_process_coverage	foreground_dataset_conformance	Confirm that all required processes are represented and that each conditional process or row is either included with data or explicitly marked not applicable with evidence. Coating shall close electricity or thermal energy, direct combustion, aqueous chemical, bath, rinse and water-balance routes; fabrication shall close fuel combustion, shielding-gas origin and release, welding slag and wet-route outputs.
validation_atomic_inventory	foreground_dataset_conformance	Confirm that every inventory card is one physical, chemical, waste or elementary exchange. Verify every part family in the representative or replacement model-specific component schedule, and reject umbrella fastener, component, energy, water, wastewater, waste or emissions rows.	agri-fab-steel-tow-roller-45-01791
validation_uuid_property	foreground_dataset_conformance	Confirm each populated Tiangong UUID by public state-100 identity, flow type, classification, property and unit group; keep fabrication_pm10_air unresolved until an exact release-compartment identity is available.
validation_reconciliation	foreground_dataset_conformance	Confirm the purchased-input, issue-ledger, internal-transfer, waste-generation, exported-waste, water and emission equations close separately for the declared period. Verify unchanged supplied-substance loss separately from combustion-product formation, including the 44/12 carbon-to-carbon-dioxide conversion and either oxidation fraction or incomplete-combustion carbon destinations. Confirm that reacted fuel is not subtracted as destroyed pollution and that opening inventory, issues, generated waste, outbound waste and formed combustion products are not double-counted; investigate and disclose unexplained gaps rather than forcing balance.
validation_double_counting	foreground_dataset_conformance	Confirm that upstream datasets exclude foreground operations already recorded and that recycling credits, outsourced services and transport are not counted twice.
