Quarter plan (31-90 days)
Balanced timeline for proof closure and quote stabilization.
Staged rollout (90-180 days)
Best for pilot validation, compliance preparation, and fallback planning.
Empty state: configure five inputs, then run the checker.
This tool is deterministic for the same inputs and shows assumptions next to each result so you can verify decisions quickly.
These conclusions answer the alias intent directly and show where 2023 launch-year assumptions are strong, weak, or uncertain.
Decision impact: Do not split into a second page for year aliases.
Decision impact: Include duty and legal-path checks before deposit, not after shipment booking.
Decision impact: Every quote and customer promise must display the test protocol and climate assumptions.
Decision impact: Use VIN-linked trim evidence and destination-market specification matching before lock-in.
Decision impact: Mark unresolved fields as 待确认/暂无可靠公开数据 and gate payment milestones accordingly.
BYD Media Hub says Dolphin Surf/Seagull reached one million cumulative units on June 30, 2025, 27 months after launch.
EU countervailing duty for BYD under Implementing Regulation (EU) 2024/2754 entered into force on October 30, 2024 and is set for five years.
NHTSA import FAQ and HS-7 declaration indicate nonconforming vehicles under 25 years require a Registered Importer pathway, with a 150% bond and 120-day conformity window.
USTR final determination notice published on September 18, 2024 sets additional duty on Chinese EV tariff lines to 100%, effective September 27, 2024.
BYD Dolphin Surf official brochure shows 30.08/38.88 kWh packs with protocol-specific range rows (NEDC and WLTP) that cannot be treated as one interchangeable number.
BYD brochure and BYD Media Hub both describe Dolphin Surf/Seagull family context but publish different market-pack values (for example dimensions and WLTP claims), so direct copy-over across regions is unsafe.
The tool score and report evidence use the same assumptions. This prevents conflicting guidance between interaction layer and content layer.
Step 1: Intent and route screening
Normalize aliases such as 2023 byd seagull ev, 2023 byd seagull, and byd seagull 2023 into one canonical decision route.
Step 2: Tool scoring with hard boundaries
Score market, buyer type, proof quality, timeline, and priority, then force redirect when legal-path assumptions conflict with route scope.
Step 3: Evidence and comparison validation
Use official specs, policy notices, proof checklist, and alternative-model comparison to reduce optimism bias in early quote decisions.
Step 4: Action decision
Convert output status into concrete next-step CTA: proceed, conditional proceed, mitigation-first, or redirect.
Step 5: Open-gap handling
If evidence is incomplete, mark the conclusion as pending and hold deposit milestones until gap-closure evidence is supplied.
| Claim | What evidence supports it | What remains uncertain | Buyer action |
|---|---|---|---|
| Official platform and scale signal | BYD Media Hub publication dated 2025/06/30 states Dolphin Surf/Seagull production reached one million units, 27 months from launch. | Plant-level output split by market and trim, and destination-market aftersales quality variance. | Use scale signal as supply-confidence input, but keep supplier-level KPI checks in contract terms. |
| Protocol-specific range divergence | BYD official Dolphin Surf brochure lists 30.08/38.88 kWh packs with NEDC 300/380 km and WLTP 232/295 km rows in the same document. | Direct conversion from one protocol to another for your duty cycle and climate. No universal public formula should be treated as guaranteed. | Disclose protocol basis in every quote and request route-specific consumption buffers. |
| Cross-market first-party spec drift exists | BYD brochure and BYD Media Hub publish different Dolphin Surf/Seagull family values by market context (for example 3925 mm vs 3990 mm length and WLTP rows 232/295 km vs 322 km claim). | One-to-one mapping from those market-pack numbers to an exact 2023 China launch trim remains 待确认/暂无可靠公开数据 without VIN-level evidence. | Treat first-party values as market-scoped references and require VIN + trim + destination spec mapping before quote lock. |
| U.S. legal import hard boundary | NHTSA import FAQ states nonconforming vehicles under 25 years must use RI pathway with bond; HS-7 declaration references conformity timeline and EPA declaration linkage. | Case-by-case engineering cost and timeline for a specific VIN or destination state-level process. | Treat U.S. public-road target as redirect by default unless legal memo and full pathway are ready. |
| U.S. tariff stack can invalidate price assumptions | USTR final determination notice states additional duty on Chinese electric vehicles is increased to 100%, effective 2024-09-27. | Importer-specific duty stacking outcomes across HTS coding, logistics, and financing costs are not one-size-fits-all. | Run a tariff-inclusive landed-cost model for any U.S.-target scenario before deposit or customer-facing price promise. |
| EU duty timing and rate baseline | EU Access2Markets notice and Regulation (EU) 2024/2754 show BYD at 17.0% countervailing duty from 2024-10-30 with five-year duration. | Future renegotiation or suspension outcomes and route-specific customs handling variance. | Run sensitivity analysis with policy uplift before commercial commitment. |
| Safety evidence applicability boundary | Euro NCAP result page for BYD Dolphin Surf shows tested model context and publication date (2025-09-08), which helps anchor variant-specific safety discussion. | Direct one-to-one transfer of that rating to every 2023 China-spec Seagull trim. Exact trim mapping remains 待确认/暂无可靠公开数据. | Request VIN-level safety and equipment mapping instead of assuming cross-market equivalence. |
| Launch-year China MSRP references | Secondary launch reports cite RMB 73,800 base for 2023 launch-year Seagull, while BYD official goods API currently shows Seagull Zhijia price band at RMB 69,800-78,800 (snapshot fetched 2026-04-21). | A stable first-party archived bulletin URL for each 2023 launch trim remains unavailable in public indexing, and direct trim-to-trim continuity to current Zhijia listing is 待确认/暂无可靠公开数据. | Use launch MSRP only as historical context and lock transactions against current invoice-backed quotations plus trim-code mapping. |
This table is a decision guardrail: when first-party values differ by market-pack context, treat each value as scope-bound instead of interchangeable.
| Dimension | Source A context | Source B context | Decision impact |
|---|---|---|---|
| Vehicle length | BYD Dolphin Surf brochure: 3925 mm (with 2500 mm wheelbase context). | BYD Media Hub article: 3990 mm stated for European Dolphin Surf context. | Do not assume one region pack equals another; length affects parking fit, insurance class assumptions, and homologation paperwork. |
| Battery pack naming | Brochure lists 30.08 kWh and 38.88 kWh packs for listed trims. | Media Hub launch article describes Active 30 kWh and Boost/Comfort 43.2 kWh pack context. | Battery-size mismatch changes real route expectations, replacement cost assumptions, and charger-time planning. |
| WLTP communication | Brochure row: WLTP combined 232 km / 295 km (plus NEDC row separately). | Media Hub article: WLTP combined up to 322 km for Boost and city WLTP up to 502 km. | Cross-document WLTP values are context-bound; quote sheets must show exact trim and source date to avoid overclaim risk. |
| Power output references | Brochure row lists 55 kW max power and 175 Nm max torque for documented trims. | Media Hub article states 65 kW/175 Nm for Active and Boost, and 115 kW/220 Nm for Comfort. | Motor-power assumptions drive performance expectations and insurance declarations; require VIN-level trim confirmation. |
| China retail price anchors over time | Secondary 2023 launch reports cite RMB 73,800 as entry MSRP. | BYD official goods API currently exposes Seagull Zhijia range RMB 69,800-78,800 (fetched 2026-04-21). | Historical launch MSRP is not a current executable quote; use live invoice evidence and trim mapping before deal lock. |
These cutoffs are the fastest way to avoid false positives from a tool-only read. Every row links a verified fact to a practical boundary.
| Area | Date / version | Verified fact | Boundary | Decision action |
|---|---|---|---|---|
| EU trade policy | Effective 2024-10-30; 5-year duration | EU notice and Regulation (EU) 2024/2754 indicate BYD is subject to a 17.0% definitive countervailing duty for BEV imports from China. | Any margin plan that ignores this uplift can be structurally wrong. | Model landed-cost sensitivity with duty-inclusive assumptions before final quote. |
| U.S. import eligibility | NHTSA FAQ and HS-7 declaration basis | For nonconforming vehicles under 25 years old, NHTSA describes Registered Importer pathway and bond requirements, with a conformity timeline. | A standard global sourcing quote does not automatically make a car U.S. road-registerable. | Treat U.S. public-road intent as redirect unless full legal pathway is documented. |
| U.S. Section 301 tariff policy | FRN published 2024-09-18; effective 2024-09-27 | USTR final determination notice lists Chinese electric vehicles under updated tariff treatment with additional duty increased to 100%. | A U.S.-target price model that omits this step-change is structurally unreliable. | Apply tariff-stack sensitivity before any U.S.-facing quote or purchase commitment. |
| U.S. emissions admissibility | EPA import guidance + forms page | EPA states Clean Air Act restrictions and requires proper import declarations (including Form 3520-1; Form 3520-21 for competition vehicles where applicable). | Without valid admissibility code and support, import and use assumptions fail. | Bundle emissions declaration evidence with customs and safety documentation. |
| China range-test method standard | GB/T 18386.1-2021 (implemented 2021-10-01) | SAMR open standard index publishes the method scope for EV energy-consumption and range testing. | China-method values should not be marketed as identical to WLTP/EPA outcomes. | Publish method basis beside every range number in proposals and contracts. |
| China automotive test cycle baseline | GB/T 38146.1-2019 (CATC-P; English edition listed) | SAMR index lists the China Automotive Test Cycle framework used in domestic methodology context. | Cross-cycle conversion remains scenario-dependent and not guaranteed by public one-line rules. | Mark cross-cycle conversion as assumption, then validate with pilot duty-cycle data. |
Use this as a go/no-go boundary map before treating any quote as executable.
| Situation | Applies when | Avoid when | Recommendation |
|---|---|---|---|
| Best-fit use case | LHD city-market deployment with complete proof pack and staged onboarding timeline. | Buyer requires immediate nationwide homologation certainty in strict regimes. | Proceed with specialist review and proof-gated contract terms. |
| EU duty-sensitive lane | Buyer models 2024-10-30+ duty uplift and keeps margin buffer for policy and customs variance. | Quote assumes pre-duty economics or ignores invoice coding impacts. | Run duty-inclusive margin sensitivity before confirming final commercial terms. |
| RHD expectation | Buyer accepts conversion complexity and non-standard lead-time risk. | Buyer expects direct mainstream RHD retail support from launch-year stock. | Treat as boundary lane; compare RHD-ready alternatives before deposit. |
| U.S. road-legal objective | Only if dedicated legal path is validated independently with RI and EPA admissibility planning. | User assumes normal import workflow is enough for registration. | Redirect to U.S. compliance-first route and hold procurement decision. |
| Proof quality | VIN, trim sheet, battery and charging docs, and condition media align. | Seller claims are not backed by auditable records. | Do not convert provisional quote to binding order until proof closes. |
| Safety evidence transfer | Published rating context matches destination trim, equipment, and variant details. | Rating from a different variant is used as universal evidence without mapping. | Treat cross-variant safety transfer as pending unless VIN-level equivalence is documented. |
Comparison exists to improve decision quality, not to force Seagull as default answer.
| Dimension | BYD Seagull (2023) | BYD Dolphin lane | Wuling Mini EV lane | Decision reading |
|---|---|---|---|---|
| Pricing anchor quality | 2023 MSRP anchor widely cited; first-party archived launch bulletin URL is not consistently public | Often sold in more export channels with clearer current retail documentation | Lower sticker entries in some markets, but high variance in listing quality | Treat headline price as planning input, not contractual truth. |
| Protocol transparency | Known CLTC legacy references plus official NEDC/WLTP split in export materials | Broader WLTP-facing communication in many export contexts | Protocol disclosure often inconsistent by channel | Protocol disclosure quality is a decision variable, not formatting detail. |
| Variant and spec drift risk | First-party sources already diverge by market pack (e.g. 3925 mm vs 3990 mm, and multiple WLTP rows) | Larger compact hatchback utility | Micro-city specialization | Do not assume one market brochure or media launch sheet fully represents all trims globally. |
| U.S. tariff-stack exposure | Legal-path complexity plus 100% additional Section 301 duty can break low-cost thesis | Same policy class exposure for China-origin BEVs; price case still needs tariff-stack verification | Also exposed when route relies on China-origin EV import path | If U.S. tariff stack is missing from the model, cost comparison is not decision-grade. |
| Regulatory burden in strict markets | High sensitivity to EU duty and U.S. import legal-path constraints | Still exposed, but often has wider destination-market precedent | Market-by-market legal fit remains highly variable | Regulatory burden can erase nominal purchase-price advantage. |
| Proof and execution discipline needed | Medium to high; VIN-level pack strongly recommended | Medium; often broader export precedent | Varies widely by listing quality and intended legal path | Documentation quality can outweigh purchase-price difference. |
Blocker-level risks are shown with mitigation actions so users can continue with a minimum viable path instead of abandoning context.
| Risk | Impact | Probability | Trigger | Mitigation |
|---|---|---|---|---|
| Cycle mismatch in customer expectation | High | Medium | CLTC number used as direct real-world promise. | Add route-specific consumption buffer and written assumption note in quote. |
| Policy-cost shock after quote lock | High | Medium | Countervailing duty or customs assumptions omitted during bid preparation. | Model policy-inclusive landed cost and maintain margin buffer before signing. |
| Documentation gap at payment milestone | High | Medium to High | VIN-level evidence unavailable when booking shipment. | Enforce proof checklist gate before final payment release. |
| Variant mismatch in safety/spec claims | High | Medium | Applying evidence from one market variant to another without VIN-level mapping. | Require VIN-linked spec mapping and retain pending status when public mapping is incomplete. |
| Legal-path assumption error (U.S./strict regimes) | Very High | Medium | Assuming global sourcing flow equals road-registration eligibility. | Mandatory legal feasibility check before procurement commitment. |
| Tariff-stack blind spot in U.S. scenarios | Very High | Medium | Section 301 additional-duty impact is excluded from landed-cost model. | Add U.S. tariff-stack calculation (including 2024-09-27 rule change) before sharing executable pricing. |
| Quote built on secondary-only launch MSRP | Medium | Medium | Decision uses media MSRP references without current supplier invoice validation. | Treat MSRP as context only and lock commercial terms against current auditable documents. |
Use scenarios to understand how the same model can move from specialist fit to redirect based on context changes.
| Scenario | Assumptions | Result | Next action |
|---|---|---|---|
| City distributor launching first 20-unit EU-adjacent batch | LHD market, full proof pack, 90-day timeline, duty-inclusive costing. | Conditional-to-specialist fit once proof checklist and duty checks clear. | Proceed with staged quote and policy sensitivity validation. |
| Private buyer wants U.S. public-road use | Seller claim only, immediate timeline, U.S. legality priority. | Redirect status with high failure probability. | Switch to U.S.-specific compliance route before any deposit. |
| Fleet pilot in GCC city service | Partial docs, 180-day rollout, fleet-trial role, explicit protocol disclosure. | Conditional fit if document and protocol gaps close early. | Run pilot and convert only after measurable duty-cycle match. |
| RHD retail campaign with tight launch date | RHD market expectation, 30-day timeline, resale-stability priority. | Boundary status due support and timeline conflict. | Evaluate Dolphin or other RHD-ready alternatives. |
| Bid relies only on 2023 launch MSRP headline | Cost-first priority, partial docs, no current invoice-backed supplier pack. | Boundary status because pricing evidence quality is insufficient. | Upgrade to invoice-backed quote stack before any deposit or customer commitment. |
| Seller copies EU 322 km WLTP claim onto unspecified 2023 stock | No VIN-level trim mapping, no pack-code disclosure, no source-date citation. | Boundary status due cross-market spec-transfer risk and potential misrepresentation. | Rebuild quote with traceable source rows (trim + market + publication date) or hold offer. |
This is the shortest actionable path when results are conditional or boundary.
| Item | Why it matters | Minimum evidence | If missing |
|---|---|---|---|
| VIN + trim mapping | Prevents wrong-battery or wrong-feature delivery risk. | Factory-consistent VIN sheet and trim code reference. | Spec drift and quote disputes at delivery stage. |
| Battery and charging documentation | Defines usable charging path and expected operational envelope. | Pack specification, declared charge-rate envelope, and charger/adapter compatibility statement. | Charging downtime or unexpected retrofit cost. |
| Range protocol disclosure | Prevents CLTC/NEDC/WLTP over-claim disputes after delivery. | Each quoted range number is tagged with test protocol and scenario assumptions. | Customer dispute and credibility loss from non-comparable numbers. |
| Condition media package | Reduces hidden quality issues before shipment. | Timestamped exterior/interior/video evidence tied to VIN. | Post-arrival condition conflict and rework expense. |
| Policy and customs assumption file | Avoids post-signature margin shock from duty and legal-path errors. | Destination duty assumptions, import declaration basis, and related documentation checklist. | Unexpected landed-cost increase or admissibility failure. |
| Route-specific compliance note | Aligns buyer promise with legal and operational reality. | Written assumptions for destination registration and usage scope. | Legal rejection or delayed market deployment. |
This section is intentionally explicit about uncertainty. Unresolved items are marked as pending so buyers avoid false confidence.
| Topic | Known public evidence | Still unresolved | Minimum executable action |
|---|---|---|---|
| Exact 2023 China launch MSRP archive link | Industry reports consistently cite RMB 73,800 base launch pricing on 2023-04-26. | Consistently accessible first-party archived trim-by-trim launch bulletin URL remains 待确认/暂无可靠公开数据. | Treat launch MSRP as context only and lock transactions against current invoice-backed evidence. |
| 2023 launch trims vs current Zhijia trim continuity | BYD official goods API currently shows Seagull Zhijia retail band (RMB 69,800-78,800) with active listing metadata. | Public one-to-one trim continuity mapping from 2023 launch SKUs to current Zhijia trim codes remains 待确认/暂无可靠公开数据. | Require supplier-provided trim code lineage and VIN-level build sheet before transferring historical assumptions into current contracts. |
| Variant-level safety transfer | Euro NCAP publishes BYD Dolphin Surf tested-model context (LHD, 2025 publication). | Direct transfer of that result to every 2023 China-spec Seagull trim is 待确认/暂无可靠公开数据. | Require VIN-level equipment mapping and destination homologation evidence. |
| Destination charging reliability curves | Official brochure and launch materials disclose nominal charge windows and power values. | Public long-run charging reliability across destination networks by climate remains limited (待确认/暂无可靠公开数据). | Run pilot charging tests and capture real-session logs before scaling volume. |
| Post-duty channel economics by importer type | EU duty rates and effective date are public for BEVs from China. | Importer-specific margin outcomes across logistics, finance, and local compliance costs are not publicly standardized. | Build account-specific landed-cost models and refresh them per policy update. |
