Parts for the goods of subclass 43230; parts of fans and ventilating or recycling hoods incorporating a fan

1. Scope and Applicability

This PCR applies to saleable parts made for air or vacuum pumps, air or other gas compressors, fans, and ventilating or recycling hoods incorporating a fan. It covers product-specific fabrication from received semi-finished material or polymer granulate, conditional aqueous surface treatment, conditional powder coating, final inspection, and conditional corrugated-box packing at the reporting site.

The PCR does not cover complete pumps, compressors, fans, or hoods; generic motors, bearings, transmissions, controls, filters, or fasteners sold independently under another product identity; installation; use, maintenance, or end-of-life of the equipment; capital equipment; or employee travel. A foreground data package shall identify the exact saleable part and include only the material and finishing routes actually used.

2. Product Category Identity

Field	Value
canonical_pcr_id	pcr.metal-products-machinery-and-equipment.general-purpose-machinery.parts-for-the-goods-of-subclass-43230-parts-of-fans-and-ventilating-or-recycling-hoods-430a0d30
classification_refs	CPC 3.0 43253 (exact semantic scope; accepted mapping is governed separately)
covered_products	Saleable compressor or air/vacuum-pump parts; fan impellers, stators, inlet or outlet aerodynamic elements, guards and supporting structural parts; and parts of ventilating or recycling hoods incorporating a fan
excluded_products	Complete equipment; liquid-pump parts; standalone generic components classified elsewhere; repair or installation services; non-saleable internal intermediates
representative_product	A drawing-controlled, saleable fan impeller or compressor/fan housing component
production_route	Product-specific metal forming or machining, aluminium fabrication, or polymer moulding; with aqueous preparation, powder coating, and packaging only when performed
market_state	Accepted saleable part at the reporting-site factory gate, in the declared coated/uncoated and packaged/unpackaged state

The CPC identity is verified from the official CPC 3.0 structure and explanatory notes. Regulation (EU) 2024/1834 is used only to clarify examples of significant fan elements and spare parts; it does not narrow the CPC category to regulated fans.

What	Provide a drawing- or specification-conforming saleable part for an air/vacuum pump, gas compressor, fan, or fan-containing ventilating or recycling hood
How much	1 kg net mass of accepted saleable part
How well	Meets the declared material grade, dimensions and tolerances, balance or fit requirements where applicable, surface condition, and acceptance test
How long or cycle	One production and release cycle to the reporting-site factory gate; service life is not part of this mass-based functional unit
reference_flow_link	The reference product output row reference_product_output equals the 1 kg reference flow

Field	Value
Reference amount	1

When constructing a foreground data package, the items listed in Required qualifiers must be declared in dataset metadata, process notes, reference flow comment, product description, or an equivalent data package field. Missing required qualifiers make the reference flow definition incomplete for that data package.

Do not subtract avoided virgin-material or recycling credits inside the foreground inventory; model them only in a separately declared downstream scenario.	mass-balance-identity

Calculation Rules

rule_id	Applies to	Formula or rule	Inputs	Output	source_ids
calc_net_consumption	materials and chemicals	Net consumption = opening stock + receipts - closing stock - documented return to supplier or inventory; internal recirculation is not counted again.	stock, receipt, issue, and return records	net input mass	mass-balance-identity
calc_reference_normalization	all non-reference rows	Normalized amount = allocated reporting-period amount / allocated accepted saleable-part mass.	allocated row amount; accepted output mass	amount per 1 kg reference product	mass-balance-identity
calc_electricity_mj	electricity rows	Electricity in MJ = metered electricity in kWh × 3.6.	metered kWh	MJ of electricity	energy-unit-identity
calc_mass_balance	each declared material route	Reconcile received net material with accepted product content, internal stock change, documented return, and each material-specific waste; investigate unexplained imbalance.	material input; stock change; accepted product composition; returns; wastes	route mass-balance check	mass-balance-identity

Data Quality Requirements

requirement_id	Applies to	Requirement	Evidence
dq_product_identity	reference product	Identify the exact part, drawing/model revision, intended equipment, material/grade, finish, and market state.	release certificate, drawing, bill of materials, product specification
dq_route_completeness	process map	Declare every actual forming, machining, moulding, joining, heat-treatment, aqueous-treatment, coating, inspection, and packing operation, including outsourced steps.	route sheet, work instructions, supplier processing records
dq_mass_completeness	material and waste rows	Reconcile at least 95% of input material mass by route; explain the residual and any moisture or stock effect rather than forcing balance.	signed mass-balance workbook and stock reconciliation
dq_metering	electricity, gas, and water	Use calibrated meters or a documented submeter/allocation hierarchy; report meter coverage and uncertainty or estimation share.	calibration certificates, utility bills, meter map, allocation log
dq_temporal_geographic	all foreground data	Use one coherent reporting period and disclose site, geography, technology, capacity use, abnormal operations, and any proxy period.	production and environmental reporting records
dq_atomic_wastes_emissions	wastes and elementary emissions	Report each actual material-specific waste and emitted substance separately; wastewater does not substitute for sludge, spent bath, or an elementary water emission.	waste register, transfer notes, monitoring and sampling records

9. Validation Rules

rule_id	Applies to	Rule	source_ids
validate_reference_flow	reference product	Confirm that reference_product_output is exactly 1 kg accepted saleable part and that required qualifiers are present.	un-cpc-3-0-structure-2025
validate_route_applicability	conditional rows and processes	Every conditional row is either supported by actual route records or explicitly marked not applicable; no absent route may receive a zero-valued pseudo-record.
validate_atomic_inventory	all inventory rows	Reject combined carriers, material families, mixed wastes, and aggregate emissions; each selected flow shall be one physical, chemical, waste, or energy exchange.
validate_uuid_identity	UUID-bearing flows	Confirm public state 100, English and Chinese baseName, flow type, classification, property, unit group, reference unit, product state, and foreground qualifiers before use.
validate_balance_and_allocation	materials, wastes, and shared utilities	Verify route mass-balance reconciliation and that allocation drivers reproduce reporting-period totals without double counting internal returns or recycling credits.	mass-balance-identity
validate_source_boundary	source-backed rules	Confirm that cited evidence is used only for its verified scope; AP-42 coating rules do not supply an empirical product-specific amount range.	us-epa-ap42-4-2-2-1
