# Curtains (including drapes) and interior blinds; curtain or bed valances

## 1. Scope and Applicability

This PCR applies to factory-gate foreground data packages for made-up textile curtains, drapes, textile interior blinds, curtain valances, and bed valances. The representative route converts purchased, finished woven polyester curtain fabric into a finished curtain by cutting, sewing and assembly, conditional in-house wet finishing, inspection, and packaging.

The PCR covers stock and custom-made products. It does not cover non-textile Venetian blinds, roller shutters, awnings, curtain rods or tracks, standalone textile fabric sold by length, upstream fibre/yarn/fabric production inside the foreground boundary, installation, use-stage cleaning, or end-of-life. Upstream production of every purchased product input remains connected through a qualifying dataset.

The foreground boundary begins when purchased finished curtain fabric and separately purchased trims and packaging materials are received at the manufacturing site. It includes directly controlled cutting, sewing, accessory attachment, conditional wet finishing, inspection, rework handling, packaging, utilities, wastewater, and solid waste up to release of the packaged finished product at the factory gate.
