Cards with a magnetic stripe

1. Scope and Applicability

This PCR applies to cradle-to-factory-gate production of finished, unpackaged physical cards whose data-recording feature is a magnetic stripe. It covers blank or printed cards and includes magnetic-stripe encoding, embossing, or personalization only when the manufacturer performs those operations before the declared factory gate.

Smart cards containing an integrated circuit, other unrecorded magnetic media, card readers, software, shipment packaging, distribution, card use, and end-of-life are excluded. A card that combines a magnetic stripe with an integrated circuit is outside this PCR unless the foreground product is demonstrated to remain classified and marketed as a magnetic-stripe card rather than a smart card. The official CPC structure identifies CPC 47910 separately from CPC 47920 smart cards and CPC 47530 other unrecorded magnetic media (un-cpc-3-0-structure-2025).

The representative route converts purchased rigid PVC sheet and magnetic-stripe film through screen and offset printing, route-specific gloss-oil application, sheet assembly and lamination, card punching, finishing, inspection, and any declared pre-gate personalization. This sequence is supported by the manufacturer-origin technical process in watchdata-cn103699921a; the plastic-card printing, drying, adhesive-application and laminating boundary and its ink, coating, cleanup-material, isopropanol and VOC records are supported by md-comar-26-11-19-18. A producer using another specific substrate, printing system, coating or stripe-application route must add or mark not applicable each affected atomic exchange and disclose the route deviation; no representative-route row may be used as a proxy.

7. Allocation and Co-product Handling

rule_id	Applies to	Rule	source_ids
allocation_avoid	shared operations and meters	Avoid allocation by subdividing separately metered lines, products, production orders, or time periods wherever technically feasible.
allocation_shared_electricity	shared electricity	When subdivision is not feasible, allocate shared electricity using measured machine operating time multiplied by rated or measured load; use finished-product mass only when the reporting products use materially comparable operations, and disclose the method.
allocation_scrap	PVC card scrap	Assign no avoided-burden credit inside the foreground process. Report scrap mass and treatment route separately; any recycling substitution or downstream credit belongs to the declared downstream model.
allocation_co_products	saleable co-products	If a separately saleable co-product occurs, first subdivide its process. If subdivision is impossible, use a documented physical causal relationship; use economic allocation only when no defensible physical relationship exists and disclose price period and sensitivity.

dq_upstream	background datasets	Match material form, recycled content, geography, technology, and reference period as closely as available; identify every proxy and sensitivity-critical mismatch.	dataset-selection log and supplier declarations

9. Validation Rules

rule_id	Applies to	Rule	source_ids
validate_reference_output	reference flow	Confirm that finished_magnetic_stripe_cards equals 1 kg after normalization and uses the declared factory-gate, unpackaged product state.
validate_atomic_inventory	inventory rows	Confirm that each row denotes one concrete product, waste, or energy exchange; reject umbrella utility, material, packaging, waste, or emission labels.
validate_uuid_identity	UUID-bearing rows	Confirm flow type, classification, flow property, unit group, product state, and the row-specific use against the public state-100 TianGong record; leave unresolved identities blank rather than substituting proxies.
validate_period_alignment	foreground records	Confirm that material, solvent, water, fuel, electricity, product, waste and direct-emission quantities use the same site, lines, product scope, and accounting period.
validate_mass_reconciliation	non-fuel process materials and outputs	Perform the declared dimensionally complete non-fuel material balance and constituent isopropanol balance; disclose unresolved imbalance, composition assumptions, work-in-progress changes, recovery and internal recirculation.
validate_conditional_routes	printing cleanup and thermal supply	Require positive records or an explicit not-applicable justification for every conditional row. A solvent-free claim must be supported by formulation and issue records; a no-cleanup claim by operating records; and a no-natural-gas claim by energy-supply and burner records.	md-comar-26-11-19-18
validate_boundary_disclosure	dataset metadata	Confirm disclosure of substrate, stripe specification, printing and curing route, personalization state, geography, period, scrap treatment, combined integrated-circuit features, and shipment-packaging exclusion.	un-cpc-3-0-structure-2025

10. Published Dataset Profile

Field	Value
dataset_role	Foreground production dataset for magnetic-stripe cards
downstream_use	secondary_dataset; background_dataset after independent review and publication readiness checks
allowed_use	Cradle-to-gate product footprints and lifecycle models requiring a declared magnetic-stripe-card supply, when substrate, technology, geography, period, personalization state, and boundary are compatible
excluded_use	Smart cards or integrated-circuit-card proxies; other magnetic media; card use or end-of-life without added downstream processes; packaged delivery without separately modelled packaging
required_metadata	canonical PCR id; CPC reference; product specification; substrate and recycled content; dimensions and mean mass; stripe specification; blank/encoded/embossed/personalized state; print and curing technology; site geography; reference period; factory-gate and packaging boundary; allocation method; background dataset choices
required_quality_disclosure	metering and mass-measurement coverage; count-to-mass sampling; material and solid-output reconciliation; shared-electricity allocation; data gaps and proxies; scrap contamination and treatment; unresolved UUID and range-evidence needs
update_trigger	Change in substrate, stripe construction, printing or curing technology, personalization scope, site or electricity supply, recycled content, allocation method, product specification, or a material foreground intensity; otherwise review at least every three years
