1. Scope and Applicability

Cover the full residual natural chemical-mineral category, not only barytes: natural barium sulphate (barite/barytes), natural barium carbonate (witherite), natural borates/concentrates (including actual colemanite, tincal, ulexite or another separately identified natural borate), qualifying naturally occurring boric acid, fluorspar, natural magnesium sulphates kieserite and epsomite, and other individually demonstrated qualifying natural chemical minerals such as strontianite or celestine. Residual coverage is open to an actual named geological chemical mineral only after confirming its identity/state and absence from another more specific mineral category; it is not all minerals under shared HS253090. Current CPC3 notes/detail name16190 without family explanation or current HS2022 correspondence; official CPC2.1 historical correspondences identify HS251110/251120/252800/252921/252922/253020 and shared253090. These and original HS2022 states support this candidate boundary, not a claimed current accepted HS mapping. Raw, sorted, washed, crushed, ground or physically concentrated mineral gates are distinct actual states. Barite washing/jigging/tabling/flotation/heavy-media/magnetic separation, colemanite physical concentration/grinding, and fluorspar physical concentration/dewatering are conditional examples, not one recipe applied to every family. Witherite, natural magnesium sulphates, natural boric acid and residual strontium minerals need their own actual mine/sorting/preparation and gate protocols; no unsupported common flotation, dissolution or crystallization route is imposed. HS25Note1 normally excludes calcination/roasting and crystallization, but heading2511 expressly admits natural witherite whether or not calcined excluding barium oxide; heading2528 admits natural borates/concentrates whether or not calcined and excludes borates separated from natural brine. Include actual admitted natural-mineral calcination with measured phase changes, crystal-water loss, fuel and emissions, not automatic synthetic-salt or oxide manufacture. Naturally occurring boric acid qualifies only with geological natural origin and not more than85% H3BO3 on independently measured dry weight; manufactured acid produced by reacting borate ore, or natural acid above this threshold, is outside this boundary. Strontianite may be calcined under HS25Note4 while strontium oxide is excluded; admissibility of another thermal state requires its own boundary review. Exclude synthetic/precipitated barium salts, manufactured refined borates/boric acid, brine-separated borates, HF/elemental fluorine/other manufactured fluoride chemicals, magnesium or strontium oxides and manufactured salts, formulated fertilizers/drilling fluids/chemical mixtures and finished articles. Other specifically categorized phosphates, pyrites, salt, sulphur, clay, gypsum, carbonate construction stone, graphite, feldspar/mica/talc and other nonchemical minerals use their own boundaries. Include actual development/rehabilitation, attributable infrastructure, extraction, preparation, admitted heat treatment, controls, storage/loading and expressly included receipt delivery; document lifetime attribution and upstream providers, never zero unknown burdens. wco-chemical-minerals-2022, unsd-chemical-minerals-scope-2026, usgs-barite-2022, usgs-fluorine-2017, eti-colemanite-preparation-2026, ifc-mining-2007

4. Measurement and Unit Rules

rule_id	Applies to	Required property	Required unit	Rule
reference_basis	final_product	Mass	kg	D is the positive accepted net gate-output total in kg. Exclude packaging and cancelled internal transfers. cp_output records D; every card uses per 1 kg reference flow.
conversion	utility and material rows	Declared row property	kg; m3; MJ	Retain raw readings. Electricity: 1 kWh = 3.6 MJ. Mass/volume conversion requires measured density, temperature and applicable pressure; retain water content and active chemical fraction.
category_balance	production	Mass	kg	Independently weigh positive accepted net as-received gate total D kg excluding packaging/rejects/returns and matching stocks; every exchange divides by the same selected-product D. For measured wet-basis free-water fraction w,0 <= w <1, dry mass = D(1-w); use a phase-preserving moisture method, not ignition loss that removes hydrate water or carbonate CO2. For measured dry-basis actual mineral/species fraction g, contained species mass = D(1-w)g; state mineral formula/hydration and assay method. Barite is BaSO4, witherite BaCO3; assay reported as Ba converts to the declared species using molar-mass ratio only with confirmed speciation, not one interchangeable barium product. Fluorite is CaF2; as-F assay converts to CaF2 using M(CaF2)/(2M(F)) only when that F is confirmed in fluorite; fluoride-ion/other F species are separate. Boron assay as-B2O3 equivalent is not actual oxide: elemental B mass = B2O3-equivalent mass2M(B)/M(B2O3), preserving assay basis and without asserting a borate mineral purity. Natural H3BO3 dry fraction gH <=0.85 requires measured species and geological origin; as-B alone cannot establish H3BO3 if other borates are present. Identify kieserite/epsomite and retained hydration independently; neither crystal-water release nor sulfate assay establishes free water or pure MgSO4. Actual admitted calcination uses independent input/output weighing, phases, free/structural water, carbonate CO2 and dust balances; no unchanged hydrate mass, fixed yield or assumed conversion. Recovery uses matched input/output contained identified species after stock correction, not output grade alone. Reconcile feed solids, accepted grades, actual co-products, waste rock/tails/dust, thermal losses and stocks, plus fresh/recycled/evaporated/discharged water separately. No empirical purity, yield, reagent dose or utility intensity defaults.

5. System Boundary

These and original HS2022 states support this candidate boundary, not a claimed current accepted HS mapping.

Barite washing/jigging/tabling/flotation/heavy-media/magnetic separation, colemanite physical concentration/grinding, and fluorspar physical concentration/dewatering are conditional examples, not one recipe applied to every family. Witherite, natural magnesium sulphates, natural boric acid and residual strontium minerals need their own actual mine/sorting/preparation and gate protocols; no unsupported common flotation, dissolution or crystallization route is imposed. HS25Note1 normally excludes calcination/roasting and crystallization, but heading2511 expressly admits natural witherite whether or not calcined excluding barium oxide; heading2528 admits natural borates/concentrates whether or not calcined and excludes borates separated from natural brine. Include actual admitted natural-mineral calcination with measured phase changes, crystal-water loss, fuel and emissions, not automatic synthetic-salt or oxide manufacture. Naturally occurring boric acid qualifies only with geological natural origin and not more than85% H3BO3 on independently measured dry weight; manufactured acid produced by reacting borate ore, or natural acid above this threshold, is outside this boundary.

boundary_partition	all exchanges	Include actual conditioning, storage, handling and pollution controls through the declared gate. Account for attributable construction and closure with a disclosed lifetime-output basis or justified exclusion and sensitivity. Separate purchased fuel supply from foreground combustion and purchased treatment from site releases.
boundary_completeness	inventory	Cards define individual likely exchanges and route conditions, not an exhaustive site audit. Add each actual absent chemical, waste, resource, land transformation and pollutant as its own row. Absence, measured zero and unknown must be distinguished.

7. Allocation and Co-product Handling

rule_id	Applies to	Rule	source_ids
allocation_hierarchy	joint production	Prefer process subdivision or defensible system expansion; otherwise use demonstrated physical causality. Use economic allocation only with consistent period, price, currency and sensitivity when physical causality is unavailable. Retain the unallocated inventory.	`ef-allocation-2021`
allocation_product	reference and co-products	Subdivide family extraction, physical preparation, admitted thermal treatment and shared controls. Retain unallocated joint inventories and independently accepted co-output amounts/specifications; impurities within one accepted mineral are not separate co-products. Separate fluorspar/metal concentrates or barite/other recovered mineral products with actual causality, or matched period price/grade economic allocation and sensitivity when causality is unavailable. Rejects are waste unless independently established as saleable product with fate; purchased same-family feed carries upstream burden or justified cut-off. Attribute development/closure once over measured lifetime accepted outputs. No automatic avoided synthetic salt, acid, fertilizer, drilling fluid or waste-disposal credits.
allocation_waste	waste and recycling	Classify each output by physical state and actual fate. A sale does not automatically make a residue a co-product; internal recycling receives no avoided-product credit. Apply treatment burdens once.

System boundary rules · 3

Rule ID	Applies to	Rule	Source IDs
`boundary_operations`	site	Cover the full residual natural chemical-mineral category, not only barytes: natural barium sulphate (barite/barytes), natural barium carbonate (witherite), natural borates/concentrates (including actual colemanite, tincal, ulexite or another separately identified natural borate), qualifying naturally occurring boric acid, fluorspar, natural magnesium sulphates kieserite and epsomite, and other individually demonstrated qualifying natural chemical minerals such as strontianite or celestine. Residual coverage is open to an actual named geological chemical mineral only after confirming its identity/state and absence from another more specific mineral category; it is not all minerals under shared HS253090. Current CPC3 notes/detail name16190 without family explanation or current HS2022 correspondence; official CPC2.1 historical correspondences identify HS251110/251120/252800/252921/252922/253020 and shared253090. These and original HS2022 states support this candidate boundary, not a claimed current accepted HS mapping. Raw, sorted, washed, crushed, ground or physically concentrated mineral gates are distinct actual states. Barite washing/jigging/tabling/flotation/heavy-media/magnetic separation, colemanite physical concentration/grinding, and fluorspar physical concentration/dewatering are conditional examples, not one recipe applied to every family. Witherite, natural magnesium sulphates, natural boric acid and residual strontium minerals need their own actual mine/sorting/preparation and gate protocols; no unsupported common flotation, dissolution or crystallization route is imposed. HS25Note1 normally excludes calcination/roasting and crystallization, but heading2511 expressly admits natural witherite whether or not calcined excluding barium oxide; heading2528 admits natural borates/concentrates whether or not calcined and excludes borates separated from natural brine. Include actual admitted natural-mineral calcination with measured phase changes, crystal-water loss, fuel and emissions, not automatic synthetic-salt or oxide manufacture. Naturally occurring boric acid qualifies only with geological natural origin and not more than85% H3BO3 on independently measured dry weight; manufactured acid produced by reacting borate ore, or natural acid above this threshold, is outside this boundary. Strontianite may be calcined under HS25Note4 while strontium oxide is excluded; admissibility of another thermal state requires its own boundary review. Exclude synthetic/precipitated barium salts, manufactured refined borates/boric acid, brine-separated borates, HF/elemental fluorine/other manufactured fluoride chemicals, magnesium or strontium oxides and manufactured salts, formulated fertilizers/drilling fluids/chemical mixtures and finished articles. Other specifically categorized phosphates, pyrites, salt, sulphur, clay, gypsum, carbonate construction stone, graphite, feldspar/mica/talc and other nonchemical minerals use their own boundaries. Include actual development/rehabilitation, attributable infrastructure, extraction, preparation, admitted heat treatment, controls, storage/loading and expressly included receipt delivery; document lifetime attribution and upstream providers, never zero unknown burdens.	wco-chemical-minerals-2022, unsd-chemical-minerals-scope-2026, usgs-barite-2022, usgs-fluorine-2017, eti-colemanite-preparation-2026, ifc-mining-2007
`boundary_partition`	all exchanges	Include actual conditioning, storage, handling and pollution controls through the declared gate. Account for attributable construction and closure with a disclosed lifetime-output basis or justified exclusion and sensitivity. Separate purchased fuel supply from foreground combustion and purchased treatment from site releases.
`boundary_completeness`	inventory	Cards define individual likely exchanges and route conditions, not an exhaustive site audit. Add each actual absent chemical, waste, resource, land transformation and pollutant as its own row. Absence, measured zero and unknown must be distinguished.

Allocation rules · 3

Rule ID	Applies to	Rule	Source IDs
`allocation_hierarchy`	joint production	Prefer process subdivision or defensible system expansion; otherwise use demonstrated physical causality. Use economic allocation only with consistent period, price, currency and sensitivity when physical causality is unavailable. Retain the unallocated inventory.	ef-allocation-2021
`allocation_product`	reference and co-products	Subdivide family extraction, physical preparation, admitted thermal treatment and shared controls. Retain unallocated joint inventories and independently accepted co-output amounts/specifications; impurities within one accepted mineral are not separate co-products. Separate fluorspar/metal concentrates or barite/other recovered mineral products with actual causality, or matched period price/grade economic allocation and sensitivity when causality is unavailable. Rejects are waste unless independently established as saleable product with fate; purchased same-family feed carries upstream burden or justified cut-off. Attribute development/closure once over measured lifetime accepted outputs. No automatic avoided synthetic salt, acid, fertilizer, drilling fluid or waste-disposal credits.
`allocation_waste`	waste and recycling	Classify each output by physical state and actual fate. A sale does not automatically make a residue a co-product; internal recycling receives no avoided-product credit. Apply treatment burdens once.

Validation rules · 3

Rule ID	Applies to	Rule
`validate_reference`	final_product	Verify 1 kg, positive D, product state, property/unit and every required qualifier. Each dataset fixes one product and route.
`validate_balance`	site	Independently weigh positive accepted net as-received gate total D kg excluding packaging/rejects/returns and matching stocks; every exchange divides by the same selected-product D. For measured wet-basis free-water fraction w,0 <= w <1, dry mass = D(1-w); use a phase-preserving moisture method, not ignition loss that removes hydrate water or carbonate CO2. For measured dry-basis actual mineral/species fraction g, contained species mass = D(1-w)g; state mineral formula/hydration and assay method. Barite is BaSO4, witherite BaCO3; assay reported as Ba converts to the declared species using molar-mass ratio only with confirmed speciation, not one interchangeable barium product. Fluorite is CaF2; as-F assay converts to CaF2 using M(CaF2)/(2M(F)) only when that F is confirmed in fluorite; fluoride-ion/other F species are separate. Boron assay as-B2O3 equivalent is not actual oxide: elemental B mass = B2O3-equivalent mass2M(B)/M(B2O3), preserving assay basis and without asserting a borate mineral purity. Natural H3BO3 dry fraction gH <=0.85 requires measured species and geological origin; as-B alone cannot establish H3BO3 if other borates are present. Identify kieserite/epsomite and retained hydration independently; neither crystal-water release nor sulfate assay establishes free water or pure MgSO4. Actual admitted calcination uses independent input/output weighing, phases, free/structural water, carbonate CO2 and dust balances; no unchanged hydrate mass, fixed yield or assumed conversion. Recovery uses matched input/output contained identified species after stock correction, not output grade alone. Reconcile feed solids, accepted grades, actual co-products, waste rock/tails/dust, thermal losses and stocks, plus fresh/recycled/evaporated/discharged water separately. No empirical purity, yield, reagent dose or utility intensity defaults.
`validate_coverage`	handoff	Verify each applicable exchange, its provider or environmental compartment and final waste fate; identify skipped checks, unresolved identities, missing measurements and upstream gaps. Errors or unassessed mandatory coverage cannot be labelled complete.
