1. Scope and Applicability
This rule covers a finished textile floor covering in the residual category, represented here by needle-felt flooring made from polyester staple fibre. Declare the actual fibre, bonding and backing configuration. The verified CPC headings place knotted, woven, and tufted coverings in separate categories; those products are excluded. Felt supplied as unfinished textile material, plastic floor covering, installation, use and end-of-life are outside this factory-gate product rule. The needle-felt process and optional backing are supported by ec-jrc-textiles-bref-2023; the classification boundary is supported by unsd-cpc3-2025.

6. Process Inventory Structure
Process Map
| process_id | process_name | inclusion | inclusion_condition | role | quantitative_reference |
|---|
needle_form | Web formation and needle punching | required | Every represented needle-felt lot. | Foreground textile formation. | per 1 kg accepted finished floor covering |
back_finish | Binder and textile backing | conditional | Only when an aqueous styrene-butadiene binder or polyester nonwoven backing is actually applied; record each exchange separately. | Foreground reinforcement. | per 1 kg accepted finished floor covering |
cut_accept | Cutting and acceptance | required | Every represented lot. | Foreground finishing and reference output. | per 1 kg accepted finished floor covering |
Internal web transfers between these operations are not separately counted as purchased inputs or final outputs. Other fibre, binder, backing and waste compositions require their own atomic rows and identity review before a dataset claims coverage.

allocation_review | co-products | Record any marketable co-product separately. If it shares indivisible inputs and no measured physical driver is justified, flag the lot for methodology review instead of inventing a fixed allocation fraction. | |
