1. Scope and Applicability

This PCR covers managed cultivation of Camellia sinensis, plucking of tender shoots and leaves, green-leaf reception, named primary tea-processing routes, grading, storage, and hand-off of dry tea at a declared primary-processing gate. It is written for tea leaves classified as CPC 3.0 01620 and uses the verified platform product flow Tea as the reference identity for the processed tea hand-off.

The route alternatives are explicit rather than universal. Green tea uses enzyme inactivation or fixation, optional rolling or shaping, and drying; black tea uses withering, rolling or maceration, oxidation, and drying; oolong tea uses withering, tumbling or partial aeration, rolling, partial oxidation, and drying; white tea uses withering and drying without a required rolling or oxidation step; yellow tea uses enzyme inactivation, yellowing, and drying; dark tea uses enzyme inactivation, rolling, piling or post-fermentation, and drying. A dataset must select one named route for each lot.

This PCR excludes herbal or fruit infusions, tea beverages, extracts, concentrates, instant tea, scented or flavoured tea, decaffeination, consumer brewing, packaging presentation, retail, and downstream distribution. It does not select a residual or n.e.c. product category.

2. Product Category Identity

FieldValue
canonical_pcr_idpcr.agriculture-forestry-and-fishery-products.products-of-agriculture-horticulture-and-market-gardening.tea-leaves
classification_refsCPC 3.0: 01620 Tea leaves; mapping relation: narrower
covered_productsNamed dry tea products made only from Camellia sinensis: green, black, oolong, white, yellow, and dark tea, with the selected primary-processing route disclosed
excluded_productsHerbal or fruit infusions; tea beverages; extracts; concentrates; instant tea; scented or flavoured tea; decaffeinated tea; consumer-prepared tea; packaged retail presentation

market_stateDry, graded tea at the declared primary-processing gate, with tea type, moisture, grade, lot, route, and storage condition disclosed

The verified platform identity is Tea rather than a farm-gate fresh-leaf flow. The PCR therefore keeps CPC 01620 as the coverage classification while declaring a processed-tea gate so that the platform identity and the methodology boundary are not silently conflated.

Required qualifiersCamellia sinensis; named tea type; dry made-tea condition; grade; moisture; lot or campaign; declared primary-processing gate; packaging excluded

The platform Tea flow has no treatment-standard route or gate metadata. The declared PCR gate is therefore the post-primary-processing, post-grading, pre-packaging hand-off of dry tea. Fresh tea leaves, withered leaves, oxidized leaves, and process residues remain route-specific foreground states and are not assigned the finished-tea UUID merely because they share a product family.

Each foreground dataset must explicitly select one actual route, declared gate, product state and output row. Reconcile the selected terminal route with reference_product_at_declared_handoff; normalize that handoff output to the reference quantity and retain preceding-stage outputs as measured transfers. Raw weighing, mass reconciliation and lot traceability requirements continue to apply.

The sole reference output is reference_product_at_declared_handoff, receiving the selected actual route product at the declared gate. Existing route-output ids identify the source and physical state; they are no longer individually fixed to the reference quantity.

measurement_05perennial plantation attributionMass and area-timekg, m2, and m2·yearLink establishment, replacement, pruning, land occupation, and termination records to the production period and allocate them only once to the tea output.

5. System Boundary

The foreground boundary starts with the managed tea plantation and its establishment or replacement records for the reporting period. It includes field inputs, land occupation, plantation maintenance, plucking, collection, green-leaf handling, selected primary-processing route, drying, grading, storage to the declared gate, process rejects, residues, direct emissions, wastewater where generated, and all allocation decisions required to reconcile the lot.

The boundary ends when dry, graded tea crosses the declared primary-processing gate before packaging presentation, retail, downstream distribution, consumer brewing, or beverage preparation. Background datasets for electricity, fuels, fertilizer products, crop-protection products, water supply, and treatment services are outside the foreground PCR boundary but are required when the foreground package uses them.

Process: Product Measurement at the Declared Handoff (declared_reference_handoff)

This node records the actual product handoff at the existing system boundary for reconciliation and reference-quantity normalization. It adds no physical processing and does not presume drying, cooling, storage, packaging or transport. Each data package declares one actual route, one terminal product state, moisture or dry-matter basis, and gate. Feed only the accepted product delivered by that route at that gate into this node; do not add other routes as extra inputs. Record co-products separately and apply Section 7. Count preceding inputs, losses and emissions once. Normalize using the measured accepted net mass at the handoff; this measurement node changes neither mass, yield nor allocation.

allocation_03marketable_tea_outputsiso-14044-2006Enumerate the accepted primary grade, marketable secondary grade, and recovered tea fraction when each is an intended tea output. Decision: use subdivision and direct measurement first; when outputs are physically inseparable, use allocation by measured dry tea mass as the default fallback, and disclose any economic allocation only as a documented sensitivity. Apply one method consistently to the affected process.

Treat it as an intended output only when there is a declared hand-off, destination, and product-quality record; otherwise retain the producing process burden and route it as residue or waste.
allocation_05route_alternativesiso-20715-2023-tea-classificationGreen, black, oolong, white, yellow, and dark routes are mutually exclusive per lot. Do not combine route burdens or assign oxidation, rolling, withering, fixation, or piling to a lot without route evidence.
allocation_06multi_period_attributioniso-14044-2006; ipcc-2019-refinement-afoluLink establishment, replacement, pruning, termination, inputs, outputs, and storage events to a reporting period or phase and prevent double attribution across periods.
allocation_07rework_and_rejectsmass-balance-identityRework loops, downgrades, recovery, and boundary exits must link back to the producing node; accepted tea output excludes unresolved rejects and rejected material cannot be counted at two hand-offs.

8. Foreground Data Collection, Calculation, and Quality Rules

Inventory completeness: conditional named cards are examples of individual exchanges, not an exhaustive recipe or a requirement to use those products. Before completing a foreground package, enumerate every actual planting stock, nutrient, crop-protection formulation, asset material, operating service, carrier, packaging material, waste stream and applicable elementary substance separately, using its physical identity, state, native property/unit, origin or receiving compartment, and measured or method-calculated quantity. Missing identity or quantity remains a completeness gap, never an assumed zero. Preserve the actual lot and phase basis; do not sum intermediate transfers as additional final output or duplicate burdens included in purchased services.

Retain raw site, lot, cycle and stage quantities and denominators in each collection protocol. Reconcile stocks, losses, moisture and co-product attribution first, then normalize: normalized exchange = attributable raw exchange × declared reference quantity / accepted hand-off product quantity on the same boundary and measurement basis. Apply perennial-establishment and shared-operation attribution before this normalization. Never set an internal-transfer quantity equal to the final reference quantity. Per declared reference flow means the amount, unit and product state in section 3; the data package must declare its actual route and gate.

chemical_species_mass_accountingelementary_nutrient_emissionsFinal elementary exchanges use the mass of the identified substance and one actual receiving compartment. Keep nutrient/activity ledgers separate: species-specific N2O-N × 44/28 gives N2O, NH3-N × 17/14 gives NH3, nitrate-N × 62/14 gives nitrate, and phosphate-P × 95/31 gives phosphate. If the selected flow is elemental phosphorus instead, report kg P and convert phosphate mass by 31/95 only when that species basis is evidenced. Apply a conversion exactly once only when the method output is on the elemental basis; measured compound mass is not reconverted. Total nutrient losses cannot be assigned to a single species without a supported split, and residual/retained soil nutrient is not an emission. Keep direct/indirect pathway ledgers and avoid repeating a pathway already included in the chosen method or upstream inventory. Factor uncertainty ranges screen factors on their stated basis, not final compound amounts or admissible site emissions. Normalize the attributable compound mass once using the accepted reference quantity and the matched measured output. Unknown activity, identity or compartment remains an evidence gap and blocks a completeness claim.cp_emission_records; species-specific activity ledger, method pathway and factor basis, matched accepted outputIdentity-specific exchanges and reconciled activity records

Data quality requirements

rule_idRequirement
quality_01Confirm Camellia sinensis, named tea type, route, lot, grade, moisture basis, and declared gate for every reference-flow dataset.
quality_02Prefer measured weights, meter records, invoices, batch sheets, and named input records; mark modelled values and provisional ranges explicitly.
quality_03Cover all included plantation blocks, plucking lots, processing batches, grades, residues, rejects, storage periods, and route changes in the reporting period.
quality_04Use the same mass basis and unit conversions across fresh leaf, intermediates, dry tea, residues, and rejects; document density, heating value, or meter conversion where used.
quality_05Disclose route-specific omissions, zero inputs, unresolved identities, upstream datasets, and all material exclusions from the gate.
quality_06Replace provisional reasoned ranges with site records or source-backed evidence before a final reviewed or published dataset is issued.

Environmental Coverage Calculation Rules

rule_idApplies toFormula or ruleInputsOutputsource_ids
calc_managed_environment_coverageactual managed-production nodesFor the actual owned managed-production node(s), require an applicability ledger for direct soil N2O, volatilisation/deposition-derived indirect N2O, leaching/runoff-derived indirect N2O, NH3/NOx and nutrient losses, plus actual liming/urea-use CO2. Primary calculation precedence is a representative pathway measurement, then a validated site/national method applicable to the crop, soil and management; otherwise use the compatible 2006 IPCC/2019-refined managed-soil equations and climate/input-specific factor selection for N2O and lime/urea CO2. Retain the exact edition, equation, tier, activity and factor units, climate and management applicability; no universal dose or emission factor is prescribed. Non-soil/protected routes need a method valid for their actual medium; do not force soil factors onto an inapplicable route. Use the same period/field N ledger for synthetic and organic additions, residues, actual relevant mineralisation/organic-soil and excreta pathways; demonstrate absent pathways rather than infer zero. Calculate direct and each indirect component separately, then assign each once to matching existing or new concrete cards; never add a total to its components. Convert N2O-N to molecular N2O by 44/28 once. NH3, NOx and nutrient/pesticide loss require an applicable measured or documented substance/fate model; total N/P or an unexplained balance residual is not a compound release. Keep actual receiving compartments and molecular versus elemental/reporting bases explicit; indirect formation does not remove the same N from the source ledger twice. Include actual local combustion releases separately using fuel-specific combustion-only methods; purchased electricity/heat/services retain upstream coverage once. Add one identity-specific exchange only for a supported release and reuse an existing matching card, with verified UUID or explicit unresolved identity. Missing applicable method/activity/factor/identity blocks completeness; it is not a justified zero. Attribute raw activity/release totals and normalize once to the matched accepted reference output.cp_phase1_environment_coverageattributed native environmental quantities per matched final referencereview-ipcc-soils-2019
