Parts n.e.c. of machinery for processing tobacco

1. Scope and Applicability

This rule covers the factory-gate production of an accepted, separately supplied part whose declared function is in machinery for processing tobacco. The part, its drawing or part number, material grade, compatible machine, manufacturing route, and acceptance condition must be identified. A machined alloy-steel component is the representative route; the inventory cards name its concrete exchanges. For another verified material or route within this category, the data producer must add equally specific exchanges and route records before using the dataset. The cited metal-fabrication sources establish applicable process and collection requirements, not a universal recipe or benchmark for tobacco machinery parts. [Sources: un-cpc-3-2025-notes, eu-pef-2021-annex-i, us-epa-clean-lines-2007, djordjevic-2018-conveyor]

Complete tobacco-processing machinery, food or grain machinery parts, general packaging-machine parts, tobacco itself, installation, machine operation, repair service, and part disposal are outside this product rule. A part used only for packaging is not assigned here without evidence that it is a tobacco-processing-machine part. [Source: un-cpc-3-2025-notes]

The collection protocols allocate each measured exchange directly per accepted unit. No external per-unit factor or item-to-mass conversion is imposed; the measured net mass M remains the reference quantity for that unit.

Data Quality Requirements

quality_identity	finished part and inputs	Retain drawing, compatible machine, material grade, route, acceptance state, and supplier identity.	Approved drawing, bill of materials, acceptance and supplier records.
quality_coverage	foreground exchanges	Reconcile material input, accepted part mass, rejects, chips and other recorded waste for the same period and configuration; explain any gap.	Batch mass balance and stock reconciliation.
quality_time	meter and waste records	Use a common declared reporting period and show the allocation of shared utilities and waste to accepted units.	Dated meter, production and waste logs.
