Powertrain identity must be locked before quoting
BYD official media separates SEAL U pure electric and SEAL U DM-i super-hybrid tracks; EV and DM-i rows cannot be merged by name only.
Cycle disclosure beats headline range marketing
WLTC, WLTP, and CLTC are different test frameworks. Customer-facing numbers must carry cycle labels and assumptions.
Policy cutoffs can overturn low-price logic
EU CVD rates and U.S. Section 301 additional duties can invalidate margin models when tariff scope and effective dates are ignored.
Evidence gaps must stay explicit
A complete first-party public archive for every 2023 Song Plus EV trim code is still unavailable; treat any full-trim claim as pending confirmation.
Official Song Plus EV sheet baseline
71.8 kWh | 405 km (WLTC)
First-party BYD Colombia brochure lists this launch-year market-sheet row (accessed 2026-04-26).
Declared charging envelope (same sheet)
DC 115 kW | AC 5.6 kW
Charging claims are condition-dependent; supplier promises must include infrastructure and temperature assumptions.
EU policy cutoff for China-origin BEV
BYD 17.0% CVD from 2024-10-30
EU definitive countervailing duties are manufacturer-specific and can dominate landed-cost outcomes.
Method
Every recommendation follows the same four-step method so output is reproducible and auditable.
| Step | Method | Output | Reason |
|---|---|---|---|
| Step 1 | Tool-first signal check | Fit status and risk direction | Run five controlled inputs to classify specialist, conditional, boundary, or redirect outcomes. |
| Step 2 | Protocol and trim normalization | Comparable evidence baseline | Separate WLTC, WLTP, and CLTC claims, then align battery, power, and size data to declared trim and powertrain context. |
| Step 3 | Policy and route boundary check | Executable vs non-executable lane | Map jurisdiction constraints, duty stack exposure, and legal pathway ownership before negotiation. |
| Step 4 | Scenario and fallback routing | Actionable next step | Choose continue, delay, or switch route based on risk matrix and proof checklist completion. |

Applicability
These rows define when data is applicable, when it is not, and what minimum control is required before commitment.
| Concept | Known fact | Apply when | Failure mode | Minimum action | Sources |
|---|---|---|---|---|---|
| Nameplate and powertrain scope | BYD official media lists SEAL U under both pure electric and super-hybrid (DM-i) tracks. | A quote references Song Plus / Seal U naming without full drivetrain context. | Using DM-i configuration assumptions for a pure EV route (or vice versa). | Lock BEV vs DM-i identity plus VIN-linked trim evidence before deposit. | [S2], [S3] |
| Range protocol comparability | Official Song Plus EV sheet provides WLTC figures; BYD Europe communication uses WLTP labels for SEAL U. | Any range number is used in quote, contract, or buyer memo. | Treating WLTC/WLTP/CLTC as directly interchangeable and over-promising performance. | Display cycle label next to every range figure and keep assumptions visible. | [S1], [S2], [S11], [S12] |
| Charging-time promises | BYD brochures state actual range and charging speed vary with battery temperature, charging hardware, and ambient conditions. | Negotiation language includes DC/AC charging duration commitments. | Presenting best-case charging metrics as guaranteed delivery outcomes. | Quote nominal envelope and explicitly add condition disclaimer + pilot validation. | [S1], [S3] |
| Regulatory scope boundary | EU CVD rates target China-origin BEVs under defined tariff scope, while U.S. Section 301 adds a separate tariff layer for covered EV lines. | Building landed-cost model for EU or U.S.-adjacent destination strategy. | Applying wrong tariff path or ignoring manufacturer-specific duty treatment. | Map tariff scope, manufacturer entity, and effective date before quote lock. | [S4], [S5], [S6] |
Evidence
These rows are high-impact because they can override otherwise attractive vehicle-level economics.
| Area | Date / version | Verified fact | Boundary | Action |
|---|---|---|---|---|
| EU definitive countervailing duties on China-origin BEV | EU announcement updated 2024-12-12; applies from 2024-10-30 | Manufacturer-specific rates include BYD 17.0%, Geely 18.8%, SAIC 35.3%, plus separate rates for other producers. | Scope and rate depend on vehicle class and producer identity; do not model one blended duty for all BEV offers. | Bind supplier legal entity and duty class before quote lock. |
| U.S. Section 301 additional duty for covered EV lines | 89 FR 76581 (published 2024-09-18), EV action effective 2024-09-27 | USTR determination raises additional duties on covered electric-vehicle tariff lines to 100% in 2024. | Tariff effect is classification-dependent. Wrong HTS mapping can invalidate landed-cost assumptions. | Run tariff classification check and legal review before committing commercial terms. |
| U.S. admissibility documentation path (nonconforming vehicles) | 49 CFR 591.5 + NHTSA FAQ + EPA forms (accessed 2026-04-26) | Import pathway requires declaration basis; NHTSA highlights the under-25-year constraint, and EPA lists Form 3520-1 for declarations. | Seller invoice and shipping paperwork alone do not satisfy U.S. admissibility requirements. | Assign a compliance owner and complete declaration package before deposit. |
| China test-method standards for cycle and EV energy/range | GB/T 38146.1-2019 (2019-10-18 / 2020-05-01) + GB/T 18386.1-2021 (2021-03-09 / 2021-10-01) | China publishes separate national standards for light-duty driving cycles and EV energy/range test methods. | Cross-cycle conversion is scenario-dependent; public standards do not provide a universal one-number conversion shortcut. | Keep test-cycle label in all outward-facing range and consumption rows. |
| Area | Version | Known fact | Boundary | Action |
|---|---|---|---|---|
| Official Song Plus EV market sheet (first-party) | BYD Colombia PDF (accessed 2026-04-26) | Lists 160 kW output, 71.8 kWh battery, 405 km WLTC range, DC 115 kW / AC 5.6 kW charging envelope, and 4,785 mm body length. | This row represents one market package, not every global trim. | Use as conservative baseline and cross-check by destination trim/VIN. |
| BYD Europe media and brochure context (SEAL U pure EV) | BYD Europe page + brochure (accessed 2026-04-26) | Official communication labels pure electric and DM-i tracks separately; pure EV page states up to 500 km WLTP combined. | Do not map this one-to-one to every Song Plus EV trim without VIN-level proof. | Treat this as naming/protocol boundary evidence and keep trim confirmation explicit. |
| EU CVD rate schedule | Access2Markets update (2024-12-12) + Commission release (2024-10-29) | Definitive countervailing duties on China-origin BEV include BYD 17.0%, Geely 18.8%, SAIC 35.3%, and residual categories. | Rate depends on producer identity and tariff scope; no universal blended rate is valid. | Map supplier entity and duty class before signing commercial terms. |
| U.S. Section 301 tariff schedule update | 89 FR 76581 (published 2024-09-18; EV action effective 2024-09-27) | The 2024 determination sets covered electric-vehicle additional duties at 100%. | Applies only when tariff classification and origin satisfy covered lines. | Run classification review and legal path check before deposit. |
| U.S. admissibility declarations | 49 CFR 591.5 + NHTSA FAQ + EPA Form 3520-1 guidance (accessed 2026-04-26) | NHTSA highlights the under-25-year nonconforming constraint and declaration path; EPA identifies Form 3520-1 for vehicle import declarations. | Commercial invoices and seller claims are insufficient to establish road-use admissibility. | Assign compliance owner and complete HS-7 / EPA declaration readiness before shipment. |
| China test-standard timeline | GB/T 38146.1-2019 (effective 2020-05-01) + GB/T 18386.1-2021 (effective 2021-10-01) | Standards registry confirms distinct cycle and EV energy/range test-method standards in China. | No universal public rule guarantees direct conversion from CLTC to WLTP/WLTC values. | Keep method labels explicit and avoid single-number cross-cycle promises. |
| Internal export dataset baseline | China EV Exporter dataset snapshot (2026-03-26) | Internal baseline supports route consistency checks and scenario defaults used by the checker. | Internal data is operational support, not external legal/homologation evidence. | Use for screening only; bind final commitment to first-party + regulatory evidence. |
| Conclusion | Evidence | Source refs | Updated | Status |
|---|---|---|---|---|
| EU policy layer can remove margin if manufacturer-specific CVD rates are ignored. | EU official communication lists producer-specific rates and confirms application from 2024-10-30. | [S4], [S5] | 2026-04-26 | Confirmed |
| U.S.-target pathways require tariff and admissibility gating before commercial commitment. | USTR 89 FR 76581 sets covered EV additional duties to 100%; NHTSA/EPA references require declaration-based compliance path. | [S6], [S7], [S8], [S9], [S10] | 2026-04-26 | Confirmed |
| Cycle labels (WLTC/WLTP/CLTC) must stay attached to every range row. | Official BYD materials and standards references show separate protocol contexts and condition-dependent real-world outcomes. | [S1], [S2], [S3], [S11], [S12] | 2026-04-26 | Confirmed |
| EV vs DM-i identity mismatch is a high-impact avoidable failure mode. | Official BYD model taxonomy separates pure electric and DM-i tracks under related naming. | [S2], [S3] | 2026-04-26 | Confirmed |
| A full first-party public trim-code archive for every 2023 Song Plus EV pack is not yet available. | Current official public assets provide market-sheet facts but do not expose a complete global trim-code matrix. | [S1], [S2], [S3] | 2026-04-26 | Pending confirmation |
Boundaries
Each boundary includes a concrete mitigation so users can recover instead of guessing.
| Scenario | Why it fails | Mitigation |
|---|---|---|
| Quote uses Song Plus / Seal U name but skips EV vs DM-i confirmation | The same market family name can appear in both pure EV and hybrid tracks, causing direct spec mismatch. | Confirm drivetrain type and VIN-linked trim before any commercial commitment. |
| Range claim communicated without protocol label | Customer interprets one cycle as another and expected delivered range diverges from quoted range. | Attach WLTC/WLTP/CLTC label and scenario note to each range row in quote and contract. |
| Charging duration promised as fixed outcome | Actual charging speed depends on battery state, temperature, and charger capability. | Present charging values as nominal envelope with environment and infrastructure conditions. |
| Price model built without destination duty stack | Margin appears healthy pre-policy but collapses once destination duties and classification are applied. | Run base / stressed landed-cost model before negotiation. |
| Trim purchased on screenshots only | Battery, power, or equipment can drift from listing text and invalidate route plan. | Require VIN-linked build sheet plus timestamped inspection media. |
| U.S. public-road outcome assumed by default | Legal pathway and declaration obligations are not satisfied by normal export paperwork. | Switch to legal-feasibility lane before commercial commitment. |
Alternatives
If the checker returns boundary/redirect, use this table to pick the next executable route.
| Route | Best for | Tradeoff | Switch signal |
|---|---|---|---|
| BYD Song Plus EV | Family crossover demand with controlled documentation workflow. | Needs stricter protocol labeling and trim-proof discipline. | Switch if destination legal path is unclear or proof quality cannot be upgraded. |
| BYD Seal | Sedan-focused buyers prioritizing premium cabin and design positioning. | Less crossover cargo utility; route assumptions differ by buyer profile. | Switch when buyer intent is not crossover utility but sedan positioning. |
| BYD Dolphin | Lower-ticket city EV routes with simpler operating envelope. | Smaller footprint and different demand segment than Song Plus EV. | Switch when budget sensitivity dominates and compact format is acceptable. |
| BYD Tang | Larger SUV use case with cargo and long-route expectations. | Different generation and proof complexity profile. | Switch when seven-seat or larger-SUV operating assumptions are mandatory. |
Risk map
Risk rows are actionable only when an owner is assigned and mitigation is pre-committed.
| Risk | Probability | Impact | Mitigation | Owner |
|---|---|---|---|---|
| Nameplate confusion (pure EV vs DM-i variant) | Medium | High | Add mandatory drivetrain confirmation gate in supplier checklist. | Procurement lead + technical reviewer |
| Protocol confusion (WLTC/WLTP/CLTC) | Medium | High | Tag every number with protocol and include scenario disclaimer in quote. | Sales lead + technical reviewer |
| Duty-stack underestimation | Medium | High | Use base and stressed duty cases before commercial sign-off. | Commercial manager |
| Charging claim over-promise | Medium | Medium to High | Publish charge-time assumptions and require pilot charging logs for destination conditions. | Aftersales lead |
| Trim and battery mismatch | Medium | High | Lock VIN-level build sheet and proof checklist before deposit. | Procurement lead |
| Legal admissibility mismatch in strict markets | Low to Medium | Very High | Run legal-path feasibility gate before procurement commitment. | Compliance owner |
Scenarios
These scenarios make the score easier to translate into operational action.
| Scenario | Likely result | Recommended move |
|---|---|---|
| LATAM distributor, full proof, staged rollout | Specialist fit | Proceed with proof checklist closure and duty-aware contract terms. |
| EU pilot batch, partial proof, 90-day timeline | Conditional fit | Upgrade documents, bind duty-class assumptions, then re-run cost and legal checks. |
| EU quote mixes EV and DM-i spec lines by name only | Boundary case | Pause, lock drivetrain/VIN identity, and rebuild quote with cycle-labeled data. |
| Private importer, seller claims only, urgent timeline | Boundary case | Pause and switch to proof-closure sprint before any payment. |
| U.S. public-road target with no legal memo | Redirect | Move to legal-feasibility workflow before vehicle-level negotiation. |
Proof
This is the minimum viable evidence set for dependable execution.
| Item | Why | Minimum requirement | Failure mode |
|---|---|---|---|
| Powertrain identity lock (EV vs DM-i) | Prevents drivetrain mismatch under similar nameplate labels. | Written BEV/DM-i confirmation plus VIN-linked trim evidence. | Wrong product route and contract dispute. |
| VIN and trim mapping | Prevents wrong battery/feature delivery. | VIN sheet, trim code, and supplier confirmation in writing. | Spec drift and dispute at handover. |
| Battery and charging documentation | Defines usable operating and charging envelope. | Battery details, charging-rate envelope, and condition assumptions (SOC/temperature/infrastructure). | Unexpected retrofit cost and operating downtime. |
| Range protocol disclosure | Prevents non-comparable range promises. | Each range row tagged WLTC, WLTP, or CLTC plus scenario context. | Customer expectation conflict and trust loss. |
| Condition media package | Reduces hidden quality risk pre-shipment. | Timestamped exterior/interior videos tied to VIN. | Post-arrival quality disputes and rework. |
| Policy and duty assumptions file | Avoids margin shock after signature. | Documented duty baseline, tariff classification scope, customs assumption, and fallback case. | Landed-cost miss and contract stress. |
Known vs unknown
Unknown data is explicitly labeled so decisions do not silently depend on assumptions.
| Topic | Known | Unknown | Minimum action |
|---|---|---|---|
| Complete first-party public archive for every 2023 EV trim code | First-party pages confirm market-sheet-level Song Plus EV / SEAL U facts and policy boundaries. | A complete public archive mapping every 2023 trim code to every export market pack remains pending. | Require supplier trim-code lineage and VIN-level confirmation before contract lock. |
| Global cross-nameplate mapping (Song Plus EV vs SEAL U variants) | Official materials indicate naming differences across markets and drivetrain families. | Full VIN-level public mapping across all market naming variants is not centrally published. | Treat mapping as pending until supplier provides VIN-linked homologation references. |
| Independent crash-test transfer by exact export trim | Public safety references often apply to market-specific test configurations. | Direct one-to-one transfer to all Song Plus EV listing variants is not publicly verified. | Treat safety claims as configuration-dependent unless equipment mapping is proven. |
| Long-run charging reliability by destination climate | Public spec materials provide nominal charging envelopes and condition caveats. | Public cross-climate long-cycle reliability data for all destination networks is limited. | Run pilot charging logs before large-batch rollout. |
