Carpets and other textile floor coverings, woven, not tufted or flocked

1. Scope and Applicability

This PCR applies to factory-gate foreground data packages for carpets and other textile floor coverings whose pile or surface structure is produced by weaving and is neither tufted nor flocked. It covers woven broadloom, rolls, rugs, and tiles when they retain this product identity, including products sold with integral backing or finishing layers.

Knotted carpets, tufted carpets, flocked floor coverings, felt floor coverings, resilient non-textile flooring, installation, use, maintenance, and end-of-life are excluded. Fibre, yarn, dyestuff, backing-compound, packaging, electricity, water, and waste-treatment production outside the reporting plant are represented by upstream datasets rather than recreated inside the foreground inventory.

The declared product is the saleable woven textile floor covering at the manufacturing plant gate. Wet processing, backing, coating, laminating, and other finishing steps are included only when performed for the declared product and must be disclosed as route qualifiers.

5. System Boundary

The foreground boundary begins when yarn and any separately purchased dyes, auxiliaries, backing compounds, packaging, water, and energy enter the reporting plant. It includes yarn preparation performed at the plant, weaving, conditional wet processing, conditional backing or coating, drying or curing, cutting, inspection, packing, internal scrap handling, direct emissions, and wastewater leaving the plant. The boundary ends with the net saleable woven floor covering at the plant gate.
