Jute and other textile bast fibres (except flax, true hemp and ramie), processed but not spun; tow and waste of these fibres

1. Scope and Applicability

This PCR governs foreground data packages for jute, kenaf and other eligible textile bast fibres after preparation for spinning but before spinning, including carded or drawn fibre states, tow, and fibre waste that remains a saleable product. It applies to a declared production route from accepted raw or retted fibre at the preparation facility gate through selection, batching or softening when used, carding and drawing when used, and final baling or dispatch presentation.

The PCR excludes flax, true hemp and ramie; agricultural cultivation; harvested stems; retting and primary fibre extraction unless modelled as a separately measured upstream unit process; spun yarn; woven, nonwoven or finished textile products; and fibre material sent to waste treatment rather than sold as a CPC 26170 product. A data package shall identify whether its reference product is prepared fibre, carded fibre or sliver, drawn sliver, tow, or product-grade fibre waste.

Delivered processed unspun bast-fibre product (reference_product_output)

This is the single delivered reference product. Its required qualifiers determine whether the lot is prepared fibre, sliver, tow or product-grade fibre waste.

• Selected flow: Jute and other textile bast fibres (except flax, true hemp and ramie), processed but not spun, tow and waste of these fibres f3c8c841-9fe8-4c84-9f01-5dac913d827b
• Flow property / unit: Mass 93a60a56-a3c8-11da-a746-0800200b9a66 / kg
• Amount rule: Set to the calibrated delivered lot mass at the declared moisture basis; normalize the dataset to 1 kg or 1,000 kg.

Waste flows

Off-spec jute fibre sent to waste treatment (off_spec_jute_fibre_output)

Off-spec fibre without a saleable product destination is weighed as waste and kept distinct from CPC 26170 product-grade waste.

7. Allocation and Co-product Handling

rule_id	Applies to	Rule	source_ids
allocation_avoid	shared processes producing main fibre, tow and saleable fibre waste	First subdivide metered unit processes or expand the system where this produces a transparent multifunctional result. Do not allocate a separately measured process.	ec-pef-2021-2279
allocation_physical	inseparable shared burdens	If subdivision or expansion is not feasible and output mass is a relevant physical relationship, allocate shared burdens by the dry-mass-equivalent saleable outputs measured for the same campaign. Exclude internal recirculation and waste sent to treatment from the saleable denominator.	ec-pef-2021-2279
allocation_other_relation	outputs for which mass does not represent the underlying function	If no defensible physical relationship exists, use another documented relationship such as campaign-average economic value; disclose prices, averaging period, currency, allocation factors and sensitivity to the physical alternative.	ec-pef-2021-2279
waste_product_status	tow, fibre waste, caddies and off-spec fibre	Classify each material once from evidence of destination: saleable specification and transaction evidence make it a product or co-product; a treatment obligation makes it waste. Do not model one mass as both.	unsd-cpc-ver-3-2025; ec-pef-2021-2279
