Dedicated parts for broadcast, television, display and radar apparatus

1. Scope and Applicability

This methodology covers accepted dedicated parts for broadcast/television transmission apparatus with or without reception, television cameras, general or vehicle radio receivers, television receivers, ADP or non-ADP monitors/projectors, and radar/radio navigation/remote-control apparatus. Housings, populated boards and RF/display subassemblies are not admitted by name: drawing, dedicated host fit, delivered functionality and remaining assembly must establish part status. Complete apparatus, including functioning bare apparatus without a housing, is not the reference output.

The current CPC3 note gives 47403 a title but no detailed inclusion/exclusion text. Adjacent categories separately name capacitors, resistors, bare printed circuits, valves, semiconductors and ICs. Those and generic metal/polymer stock do not become the reference product merely because a host manufacturer purchases them. Separately classified display cells, general fasteners, complete antennas and independently functional display/radar modules need separate review. Telephone/network equipment, audio/video recording/reproduction, still-camera and camcorder parts are not automatically included. Historical customs cases show a television main board can be a part, an LCD subassembly can be separately classified, and a decoder-equipped LCD module can be a complete monitor; they are not universal current CPC mappings.

excluded_products	Complete apparatus; separately named components or generic stock; modules without host evidence; parts for other hosts
representative_product	Host-fit accepted television main control circuit assembly
production_route	Actual mechanical, polymer, circuit, microwave or display route under make/buy matrix
market_state	Accepted dedicated part at declared plant gate, before host installation

3. Reference Flow

Field	Value
What	Supply of a dedicated apparatus part meeting declared drawing/interface
How much	1 kg
How well	part number and drawing revision; actual host family/model and dedicated fit; delivered functional state and remaining assembly; material grades/formulations; make/buy and supplier completed operations; electrical/RF/optical/mechanical interface and acceptance tests; configuration and net mass; site, period, supplier geography, test and packaging boundary
How long or cycle	One supply at factory gate; no host service-life claim
reference_flow_link	final_product

Field	Value
Reference amount	1
Reference product flow	Accepted dedicated apparatus part
Reference flow property	Mass 93a60a56-a3c8-11da-a746-0800200b9a66
Reference unit group	Units of mass 93a60a57-a4c8-11da-a746-0800200c9a66
Reference unit	kg
Required qualifiers	part number and drawing revision; actual host family/model and dedicated fit; delivered functional state and remaining assembly; material grades/formulations; make/buy and supplier completed operations; electrical/RF/optical/mechanical interface and acceptance tests; configuration and net mass; site, period, supplier geography, test and packaging boundary

D is the positive accepted net mass for the same part, drawing and configuration in the matched period. Weigh accepted lots on a calibrated balance, excluding transport packaging, test fixtures, rejects and free residual liquid. Small parts may use lot net mass and matched lot count; never invent unit weight. Convert count to mass only using measured net mass divided by measured accepted count of the same-configuration matched lot; packaging or another model cannot substitute. Each foreground exchange divides its attributable period quantity by D; net reference output is 1 kg.

4. Measurement and Unit Rules

rule_id	Applies to	Required property	Required unit	Rule
reference_mass	final_product	Mass	kg	cp_mass measures D; every row divides attributable period quantity by D.
units	all inventory rows	Row-specific property	kg; kWh; MJ; t km	Retain raw units and conversion evidence; electricity 1 kWh=3.6 MJ; gas retains temperature, pressure, composition and net calorific value.
balances	production	Mass	kg	Reconcile external inputs, stocks, products, waste and releases separately for each alloy, resin, paste and solvent; contained metal/element terms use their own measured composition, never gross mass as element mass. Include reactions, oxygen uptake, moisture and stocks; cancel paired internal transfers but retain rework energy.

5. System Boundary

Boundary Abstraction

Field	Value
declared_starting_condition	Declared received blank, bare board, die, display cell or completed component with already completed operations
starting_condition_role	Supplier intermediate product
product_classification_scope	Reviewed dedicated parts for broadcast, television, display and radar hosts
recursive_input_rule	Purchased same-category parts retain distinct supplier burdens; internal returns cancel transfers and receive no substitution credit.
upstream_dataset_requirement	Link actual grade, fabrication stage, geography, supplier process, utility, transport and waste receiver; unknown never means zero.
disclosure	part number and drawing revision; actual host family/model and dedicated fit; delivered functional state and remaining assembly; material grades/formulations; make/buy and supplier completed operations; electrical/RF/optical/mechanical interface and acceptance tests; configuration and net mass; site, period, supplier geography, test and packaging boundary

rule_id	Applies to	Rule	source_ids
boundary_routes	all processes	Build a drawing-based stage-by-stage make/buy/subcontract matrix. Purchased chassis, PCBA, microwave assembly or display cell carries supplier burden once; in-house routes include actual fabrication, assembly, tests, rework and controls. Never count both a purchased component and its embedded raw inputs.	cbp-n353432; rogers-materials
boundary_extensions	all processes	Not every part manufacturer makes wafers, bare boards or LCD glass. If actually in-house, add the applicable lithography, deposition/etching, plating, cleaning, lamination and packaging stages with individual chemicals, materials, utilities, wastes and species releases. Missing special-recipe evidence is a package gap, not automatic exclusion of the part family.	cbp-n353432; rogers-materials
boundary_gate	all processes	Include actual factory test electricity, destructive samples, cleaning, maintenance and control-equipment service. Host installation, whole-apparatus commissioning, user use and end of life are outside this factory-gate package and need downstream models. Justify and assess sensitivity of capital/infrastructure exclusions.	cbp-n353432

6. Process Inventory Structure

Process Map

process_id	process_name	inclusion	inclusion_condition	role	quantitative_reference
receipt	Supplier receipt and make/buy reconciliation	required	Trace the actual part drawing and delivered input state; record inbound transport and supplier operations.	Foreground manufacturing	per 1 kg reference flow
mechanical	Mechanical or polymer part manufacture	conditional	Actual sheet/extrusion cutting, machining, casting, polymer drying/moulding or dielectric shaping at the site; purchased finished housings bypass only these upstream operations.	Foreground manufacturing	per 1 kg reference flow
electronics	Host-specific circuit assembly	conditional	Actual printing/placement/reflow or insertion/soldering, optical inspection, electrical test and rework; purchased populated boards carry supplier fabrication once.	Foreground manufacturing	per 1 kg reference flow
rf_display	RF or display subassembly integration	conditional	Actual microwave substrate/die/interconnect assembly, antenna/waveguide/radome assembly, or display/backlight/optical integration; delivered part must first pass the scope gate.	Foreground manufacturing	per 1 kg reference flow
surface	Surface finishing and chemical controls	conditional	Actual degreasing, coating/cure, bonding, encapsulation or plating; include each actual formulation, reaction, rinse and control process.	Foreground manufacturing	per 1 kg reference flow
acceptance	Part acceptance, packing and dispatch	required	Part-specific drawing acceptance, functional/electrical/RF/optical tests where relevant, rejection and final net weighing.	Foreground manufacturing	per 1 kg reference flow
utilities	Attributable utilities and pollution treatment	required	Meter shared energy/water, local combustion if present, air capture and effluent treatment; no duplication of utilities already in process rows.	Foreground manufacturing	per 1 kg reference flow

Part-family qualifiers must match tests: mechanical/polymer parts use dimensional, tolerance, material and fit acceptance; boards use BOM, SPI/AOI, electrical and host-function checks; RF parts use actual frequency band, connectors and configuration for loss, gain, matching or antenna performance; display subassemblies use supplier pixel, luminance, optical and signal-interface criteria. Run only applicable tests; retain acceptance, rework, reject and test-energy records without universal thresholds. Sources: cbp-n353432; rogers-materials; keysight-radar-tests. The rows below are conditional concrete interface examples, not a universal BOM for all parts. Record not_applicable with evidence when absent, unknown when present but unmeasured, never zero by assumption.

7. Allocation and Co-product Handling

rule_id	Applies to	Rule	source_ids
allocation_subdivide	shared activities	Submeter or trace batches first; if not separable, allocate by verified labour/test time or machine time and measured load, documenting sum, rationale and sensitivity. Do not force mass allocation across different parts.
allocation_residues	scrap and rework	This candidate uses a cut-off convention: production carries input and site processing burdens; connect actual waste-receiver interfaces without default avoided-product credits. Saleable co-products require declared function, boundary and consistent method without double credit. Internal rework gains no new-product credit and retains energy/material use.

Calculation Rules

rule_id	Applies to	Formula or rule	Inputs	Output	source_ids
period_normalization	all inventory rows	Divide each attributable period exchange by D from cp_mass; final_product is 1 kg. Convert count inputs to mass using measured net lot mass and accepted count of the same configuration and lot, never invented unit mass.	period exchange; D; cp_mass	exchange per 1 kg reference flow
species_fate	ipa_air; xylene_air; fossil_co2; carbon_monoxide; nitrogen_dioxide	Use matched species concentration and exhaust volume with applicable background correction or an applicable equipment factor; reconcile solvent purchases/stocks, retention, waste, recovery, reaction and species release. Fuel carbon alone cannot calculate CO or NOx.	species data; exhaust flow; formulation and fuel records	individual species amount	epa-metal-coating

Data Quality Requirements

requirement_id	Applies to	Requirement	Evidence
identity	all rows	Verify physical/chemical identity, state, unit, provider geography/stage and Chinese name row by row; reference classification cannot substitute for actual identity.	direct flow record and supplier specification
coverage	all processes	Each actual step and atomic exchange has a quantity, unknown, or evidenced not_applicable state; citations support routes without empirical defaults.	site audit; make/buy matrix; source applicability
measurement	all rows	Match D to inputs, tests, waste, period and configuration; retain calibration, stock adjustments, elemental assays and uncertainty.	cp_mass and individual process protocols

9. Validation Rules

rule_id	Applies to	Rule	source_ids
validate_scope	final_product	Review drawing, host fit, delivered function and remaining assembly first; complete-apparatus function or a separately more specific category cannot pass this scope based on module name.	un-cpc3-notes; cbp-h325872; cbp-n059857
validate_denominator	all inventory rows	Every row uses the same positive D and accepted configuration; packaging/rejects are outside D; check raw units, count conversion and allocation individually.
validate_completeness	all processes	Reconcile make/buy, stages and physical flows; disclose missing UUID, recipe or species evidence and prevent that package claiming completeness, without excluding a part family merely for absent UUID. Count upstream burdens, embedded components and internal transfers once; unknown is neither zero nor not_applicable.
validate_water_closure	utilities; all water-bearing processes	For the same period on water mass basis, external supplied water and actual withdrawals plus opening stocks plus reaction-generated water equal water carried in product, water in external wastewater, moisture in each waste, evaporation/other water release, reaction-consumed water and closing stocks. Flow meters retain temperature/density conversions; sample waste moisture separately and determine evaporation by measurement or a transparent water balance with uncertainty. Cancel recirculation, wash returns and interprocess water transfers in matched pairs; they are neither new withdrawals nor unsupported losses.
validate_contained_metal	mechanical; electronics; rf_display; surface	For each actual metal element, use each external material's measured gross mass multiplied by its own matching elemental assay. External elemental input plus opening elemental stocks equal that element in accepted product, external swarf, rejected boards, solder residues, sludge, spent liquid, releases and closing stocks; include elemental inputs and outputs of metallization/reaction materials. Record oxidation oxygen uptake and moisture separately; alloy, paste or oxide gross mass is never elemental mass. Cancel internal metal returns/rework transfers in matched pairs without cancelling repeated processing burdens.
validate_solvent_closure	surface; electronics; rf_display	For each solvent species use measured formulation mass and that species fraction: external input, opening stock and reaction generation equal retention in product/film, content in external waste liquid/solids, externally recovered solvent, species release after controls, reaction destruction and closing stock. Cancel internal recovery/return pairs; externally recovered solvent is not also an air release. Retain capture/control fate and actual reaction evidence without assuming complete evaporation or fixed loss.
validate_balance_uncertainty	all material and water balances	Retain actual balance, meter, sampling/assay, stock and allocation uncertainty for each term; calculate and explain each closure residual. Investigate residuals outside combined measured uncertainty for omissions, period mismatch or double counting. Unknown assay, reaction fate or evaporation evidence remains unresolved rather than forcing closure with invented yield, zero or a universal tolerance.
