Woven fabrics of jute and other textile bast fibres (except flax, true hemp and ramie)

1. Scope and Applicability

This PCR covers factory-gate production of woven fabric made from jute or other textile bast fibres, while explicitly excluding flax, true hemp, and ramie. The foreground boundary begins with spun bast-fibre yarn received at the fabric mill and includes yarn preparation, warping, sizing when applied, weaving, route-specific pretreatment or finishing when performed, inspection, and packaging for dispatch.

The PCR covers greige and finished woven fabric only when the data package declares the actual fibre composition and finishing state. It excludes cultivation, retting, fibre preparation, and spinning before the yarn reaches the fabric mill; knitted, crocheted, nonwoven, tufted, and special fabrics; fabrics of flax, true hemp, or ramie; garment or article manufacture; distribution, use, and end of life. Upstream burdens of purchased yarn, utilities, chemicals, and packaging are represented by separate upstream datasets.
