Fit checker and decision report: screen your sourcing constraints, then verify supplier capability, quality evidence, and delivery assumptions before an RFQ.
Screen your 100:1 sourcing constraints and identify which supplier evidence to request next.
This is a supplier-path screen, not a live supplier directory or approval. Scores, MOQ, torque bands, and lead times are page assumptions; verify capability and timing with named suppliers.

Start with the constraint screen, then compare supplier quality evidence, lead-time support, and compliance boundaries before an RFQ.
This page uses 90:1 to 110:1 for strict go decisions and 40:1 to 220:1 for directional screening to prevent false certainty when requirement drift appears.
ICC Incoterms 2020 rules define delivery obligations, but they do not define title transfer, payment, tariffs, sanctions, or force majeure. Quotes with mixed trade-term assumptions are not directly comparable.
ISO 6336-1:2019 (confirmed in 2025) provides rating-method boundaries and explicit non-applicable cases. It should be treated as a gate input, not as complete assembled-system assurance.
IATF 16949 first edition was published in October 2016, and IATF sanctioned interpretations were updated again in November 2025 (#27-30, issued/effective November 2025). Static certificate PDFs alone are insufficient for final supplier lock.
UFLPA Public Law 117-78 sets a rebuttable presumption for goods mined/produced wholly or in part in Xinjiang and section 301 tariff exclusions continue to move over time. HS classification, exclusion status, and compliance checks should be completed before landed-cost comparison.
World Bank LPI 2023 reports an average maritime shipment journey of 44 days with 10.5-day standard deviation, and LPI 2.0 (2023-2024 dataset) highlights high unpredictability at ports/transshipment hubs. Single-point lead-time promises should be treated as probabilistic, not deterministic.
A 100:1 ratio is available across multiple gearbox architectures and stage counts. Backlash, stiffness, torque capacity, and packaging vary by model, so compare the quoted unit’s ratings under stated test conditions instead of inferring performance from its architecture name.
For an ideal reduction ratio N, output load inertia reflected to the motor shaft is Jload/N²; at 100:1 that is 1/10,000 before losses, compliance, and control effects. This can improve inertia matching, but it does not establish motor torque, thermal margin, braking capacity, or safe load handling.
Values below are decision anchors for pre-RFQ screening. Heuristic values are explicitly labeled and must be verified with supplier evidence before final commitment.
| Metric | Value / Context | Why It Matters | Source Family |
|---|---|---|---|
| Strict 100:1 decision band | 90:1 to 110:1 for go/no-go decisions on this page | Prevents drifted ratios from being treated as exact 100:1 sourcing decisions. | Page methodology rule |
| Broad screening corridor | 40:1 to 220:1 for directional screening only | Keeps the checker usable for adjacent requests while preserving strict intent boundaries. | Page methodology rule |
| Catalog-OEM default lead-time baseline | 4 to 10 weeks mass-production window in this model | Useful for fast-turn catalog programs, but often weak on advanced documentation requirements. | Internal heuristic model (explicitly non-universal) |
| Precision-OEM default lead-time baseline | 6 to 14 weeks mass-production window in this model | Represents additional process and quality controls for tighter backlash and validation needs. | Internal heuristic model (explicitly non-universal) |
| Program-OEM default lead-time baseline | 8 to 18 weeks mass-production window in this model | Captures longer ramp for full-custom and trace-heavy programs. | Internal heuristic model (explicitly non-universal) |
| Suggested shortlist size | Go=3 suppliers, Review=4, No-go=5 | Higher uncertainty requires broader supplier coverage before lock. | Page decision policy |
| Backlash path split (model baseline) | Catalog >=8 arcmin, Precision >=3 arcmin, Program >=1.5 arcmin | Tighter precision targets can force supplier-path escalation before pricing comparison. | Internal heuristic model + public catalog class pattern |

| Section 301 exclusion timeline (machinery relevance) | USTR announced 178 exclusions through 2026-11-10; the formal notice specifies 11:59 p.m. ET on 2026-11-09. Eligibility is limited to enumerated products and HTS lines. | Map the exact product description and HTS line before applying an exclusion; this is not blanket relief for China-origin machinery. | USTR announcement and formal notice (checked 2026-10-05) |

These boundaries determine when this page output is a practical decision aid and when escalation is mandatory.
| Boundary Topic | Condition | Implication | Source |
|---|---|---|---|
| Strict 100:1 intent boundary | Use 90:1 to 110:1 for go/no-go decisions. 40:1 to 220:1 is directional screening only. | Outside strict band, keep review status and confirm true architecture target before procurement lock. | Page methodology rule |
| Quality evidence boundary | Basic docs, PPAP, and full-trace requirements are treated as separate sourcing levels. | If evidence pack depth is mismatched, do not treat nominal pricing as a valid selection signal. | Tool decision policy |
| Certification boundary | When IATF-level quality governance is mandatory, non-program sourcing assumptions are incompatible without verified current scope and CSR alignment. | Escalate supplier path before comparing lead-time and unit price. | IATF official pages + page policy |
| Incoterms scope boundary | Incoterms rules do not govern title transfer, payment terms, tariffs, sanctions, or force majeure handling. | Do not compare supplier total cost on Incoterms labels alone; normalize commercial/legal assumptions first. | ICC Q&A scope statement |
| Lead-time pressure boundary | Sample and mass lead-time targets are scored jointly against path baseline windows. | Aggressive schedule compression can invalidate otherwise feasible technical paths. | Tool scoring model |
| Standards-scope boundary | ISO 6336 references are valid only inside documented scope ranges and include explicit non-applicable cases (such as zero backlash in noted examples). | Keep thermal, bearing, lubrication, and integration checks in release gate. | ISO 6336-1:2019 abstract and confirmation record |
| Trade-control boundary (US entry eligibility) | Public Law 117-78 sets a rebuttable presumption for goods mined/produced wholly or in part in Xinjiang or by entities on the UFLPA Entity List. | For US-bound business, compliance due-diligence should be passed before final price ranking. | U.S. Congress Public Law 117-78 |
| Tariff-policy time boundary | Section 301 exclusions are time-bound and can be extended, expire, or reopened by notice. | Do not reuse old duty assumptions without date-validating current exclusion status. | USTR tariff actions + exclusion notices |
| EU CBAM scope boundary | CBAM currently applies to selected sectors and is phased from transitional reporting to definitive obligations from 2026-01-01. | EU-bound projects should verify whether product codes are in CBAM scope before adding carbon-cost factors. | European Commission CBAM page |
| HS classification boundary | Schedule B is a U.S. export classification; U.S. import entries use HTSUS. Heading 8483.40 covers gearboxes and speed changers, but the exact statistical suffix depends on the product. | Confirm the current HTSUS classification and any Chapter 99 measures with the importer, customs broker, or CBP before landed-cost comparison. Do not use a Schedule B export code for an import entry. | U.S. Census import/export classification guidance + USITC HTSUS |
| Commercial comparability boundary | Public source sets are rarely transaction-normalized for identical duty and evidence requirements. | Use one RFQ template before supplier ranking; do not rank by mixed-context catalog snippets. | Open-data limitation (explicit uncertainty) |
| Regional manufacturing hubs in China | Supplier location alone does not establish architecture capability, process controls, or product quality. | Treat geography as a logistics and visit-planning factor; verify the quoted model, production site, quality records, and delivery evidence directly. | Buyer due-diligence rule; no regional capability ranking claimed |
| Material and accuracy evidence for 100:1 precision sourcing | Materials, heat treatment, accuracy grades, and load ratings depend on the offered model and its duty; no alloy or accuracy grade is a universal requirement for a 100:1 ratio. | Request model-specific drawings, material and heat-treatment evidence, accuracy class, and ratings, then assess them against the application duty and required life. | Supplier-specific evidence required; no universal threshold claimed |
| Scenario | Good Fit Signal | Not-Fit Warning | Decision Note |
|---|---|---|---|
| Industrial line needs 100:1 with moderate precision and PPAP-lite evidence | Precision-OEM path with balanced assumptions | Catalog-only shortlist based on unit price first | Confirm document package and metrology condition in sample round. |
| Project demands <=2 arcmin and full traceability | Program-OEM path with conservative assumptions | Treating low-price fast-quote offers as equivalent | Quality evidence depth dominates path choice before cost optimization. |
| Ratio requirement drifts to 130:1 during RFQ prep | Review state + architecture clarification before ranking | Locking suppliers under strict 100:1 assumptions | Ratio drift should reopen path and stage assumptions. |
| Automotive-grade quality governance required | Program path with certification verification at pre-quote stage | Comparing non-IATF and IATF offers in one bucket | Certification mismatch is a hard gating condition, not a minor adjustment. |
These counterexamples prevent false certainty and define minimum corrective actions before supplier lock.
| Assumption | Counterexample | Decision Impact | Minimum Action | Source |
|---|---|---|---|---|
| “100:1 quotes are comparable if nominal ratio matches” | Two quotes can both say 100:1 but use different Incoterms and leave tariffs/duties outside scope. | Price ranking becomes distorted and can hide true landed-cost risk. | Force one RFQ template with fixed Incoterms, duty assumptions, payment, and acceptance terms. | ICC Incoterms rules + ICC Q&A |
| “ISO 6336 rating values are enough for final release” | ISO 6336-1 states scope boundaries and non-applicable examples, so rating references alone can overstate assurance. | Late integration failures can still occur despite acceptable catalog ratings. | Treat ISO 6336 as gate input only, then require system-level thermal/life/integration validation. | ISO 6336-1:2019 standard page |
| “A certificate PDF is sufficient certification proof” | IATF customer-specific requirements continue to update, and certificate status may change over time. | Projects can pass quote review but fail governance checks before award. | Verify current status in IAF CertSearch and confirm latest applicable CSR revision before lock. | IATF news + ISO/IAF verification guidance |
| “Published lead time can be treated as deterministic” | World Bank LPI 2023 highlights sizable transit variance (44-day average with 10.5-day standard deviation). | Single-date commitments can be overly optimistic under logistics volatility. | Apply schedule buffers and review/no-go gates when sample or launch windows are compressed. | World Bank LPI 2023 release |
| “HS code can be finalized after supplier ranking” | Schedule B is for U.S. export reporting, while imported gearbox entries use HTSUS. The 10-digit classifications can differ and affect tariff treatment. | Late code corrections can invalidate quote comparability and shift landed-cost outcomes. | Confirm the current HTSUS subheading for the exact model with the importer or customs broker, then check any applicable Chapter 99 measures before ranking. | U.S. Census classification guidance + USITC HTSUS |
| “Trade-policy assumptions stay stable across RFQ cycle” | USTR Section 301 exclusions have explicit opening, deadline, and extension notices across different dates. | Using stale policy assumptions can understate or overstate duty exposure. | Add a dated policy-check gate (tariff actions, exclusions, compliance scope) before award recommendation. | USTR tariff actions and press releases |
| “Any 100:1 gearbox can handle the same load inertia” | A 100:1 worm gear and a 100:1 planetary gear behave very differently. The worm gear may suffer from high friction and low efficiency (preventing back-driving), while a planetary or harmonic drive is designed for high-efficiency servo reversing applications. | Selecting the wrong architecture leads to motor stalling or premature wear. | Specify architecture (planetary, harmonic, cycloidal) and require torque and efficiency curves across the duty cycle. | Industry standards and GAM application guides |
The checker links input validation, supplier-path branching, readiness scoring, and boundary-triggered sourcing actions.
Strict-band enforcement keeps 100:1 intent coherent and blocks ambiguous architecture decisions from being treated as final.
| Step | Logic | Output |
|---|---|---|
| Input normalization | Validate ratio, torque, backlash, annual volume, lead time, sample deadline, and sourcing constraints. | Clean inputs or recoverable boundary/error state |
| Supplier path resolution | Map customization depth, quality-pack level, certification demand, and risk profile to catalog / precision / program path. | Primary supplier path baseline |
| Directional screen scoring | Blend ratio-fit, precision-fit, lead pressure, volume-fit, certification-fit, and evidence-pack compatibility into one score. | Page-defined heuristic score + risk level |
| Boundary + action mapping | Apply strict-band rules, mismatch triggers, and conservative penalties to assign go/review/no-go with next actions. | Executable RFQ path with supplier-count guidance |
| Commercial and certificate verification gate | Normalize Incoterms/commercial terms and verify certificate status before price-led ranking. | Comparable quote set and lower compliance-reversal risk |
If result status is review/no-go, lock a normalized RFQ template before supplier ranking to avoid mixed-context decisions.
Unknown or partial evidence is explicitly marked instead of forcing fake certainty.
| Option | Strength | Tradeoff | Data Confidence | Typical Fit |
|---|---|---|---|---|
| Catalog OEM path | Fast quote cycle and simple commercial onboarding | Limited evidence depth for tight precision or trace-heavy programs | Public catalogs often expose broad specs but less process detail under strict evidence requirements | Cost-sensitive projects with moderate precision and basic documentation |
| Precision OEM path | Better fit for tighter backlash and engineering-review workflows | Longer delivery and higher qualification overhead versus catalog-only path | Public references typically provide more structured technical disclosures than economy catalogs | Mainstream industrial 100:1 projects needing stronger evidence quality |
| Program OEM path | Best compatibility with full-custom requirements, traceability depth, and strict quality governance | Longest ramp and highest process overhead | Open pages often confirm capability themes but not normalized transaction metrics | Safety-critical or audit-heavy sourcing programs |
| Broker/distributor shortcut path | Can accelerate communication and initial vendor access | Often weakens direct process visibility and evidence traceability | Data continuity may be partial across multi-layer sourcing chains | Exploration phase only, not final lock without direct evidence chain |
| Option | Numeric Signal | Limit / Counterexample | Decision Use | Source Family |
|---|---|---|---|---|
| Ratio-intent coherence | Strict band 90-110 vs broad 40-220 screening corridor | Outside strict band, go decisions are blocked to avoid ambiguous architecture commitments. | Protects keyword intent from scope drift during RFQ. | Page model rule |
| Lead-time pressure model | Path windows: catalog 4-10w, precision 6-14w, program 8-18w; tighter targets incur readiness penalties. | These values are heuristic and must be confirmed by actual supplier evidence packs. | Turns schedule assumptions into explicit risk signals. | Internal model (explicitly marked) |
| Quality evidence ladder | Basic / PPAP / full-trace map to increasing process-control expectations. | Missing evidence should block direct ranking even when nominal specs look similar. | Prevents false equivalence across supplier quote packages. | Page decision framework |
| Certification gate signal | IATF 16949 first edition published in Oct 2016; SI #27-30 were issued/effective in Nov 2025. | Static certificate artifacts can lag current status or CSR revision requirements. | Adds a hard compliance gate before cost-based ranking. | IATF official SI page + page rule |
| Standards context gate | ISO 6336-1:2019 confirmed in 2025; scope includes explicit applicability ranges and non-applicable examples. | Do not over-interpret catalog capacity references as complete project assurance. | Keeps gate-0 tool output aligned with downstream validation needs. | ISO 6336-1 page |
| Logistics variance context | World Bank LPI 2023 reports 44-day mean maritime journey and 10.5-day standard deviation across 139 countries. | Macro transport variability cannot predict one supplier exactly, but it is a valid buffer signal for planning. | Adds schedule-risk calibration when comparing aggressive lead-time promises. | World Bank LPI 2023 release |
| UFLPA compliance clock | Public Law 117-78 enacted 2021-12-23 and sets Section 3 effective date at 180 days (2022-06-21). | Legal entry eligibility can override commercial attractiveness for affected supply chains. | Moves compliance screening ahead of price ranking in US-bound decisions. | U.S. Congress Public Law 117-78 |
| Section 301 exclusion timing | USTR announced 178 exclusions through 2026-11-10; the formal notice specifies 11:59 p.m. ET on 2026-11-09. | Only enumerated products/HTS lines qualify. Confirm the exact tariff line and date; this is not a blanket machinery exclusion. | Require product-level tariff validation before landed-cost comparison. | USTR announcement and formal notice (checked 2026-10-05) |
| CBAM phase boundary | The definitive regime began 2026-01-01; the 2026-09-30 Commission assessment retained the 50-tonne threshold and reports 0.87% of embedded emissions below it. | Only scoped sectors/codes are in scope; carbon-cost assumptions need code-level confirmation. | Prevents over-applying carbon cost in EU-bound quote normalization. | European Commission CBAM threshold assessment (2026-09-30) |
Risks are grouped by misuse, cost, and scenario mismatch so each has an executable mitigation path.
| Risk | Trigger | Impact | Mitigation |
|---|---|---|---|
| Intent drift risk | Using non-100 ratios while treating output as strict 100:1 go decision | Wrong supplier path lock and avoidable redesign loop | Keep strict-band enforcement and reopen architecture assumptions when ratio drifts. |
| Evidence mismatch risk | Comparing suppliers with different quality-pack depth as if equivalent | Audit failure or launch delay after sample stage | Normalize RFQ evidence checklist before quote ranking. |
| Schedule compression risk | Lead-time targets below path baseline without process concessions | Late sample delivery and unstable launch timing | Use conservative mode and escalate path or timeline before commitment. |
| Certification mismatch risk | IATF-required project sourced under generic ISO assumptions | Compliance rejection and program restarts | Treat certification as hard gate and verify current certificate scope early. |
| Commercial scope mismatch risk | FOB/CIF/DDP and payment/tariff assumptions are mixed during quote comparison | Hidden landed-cost variance and false price advantage | Normalize Incoterms and non-Incoterms commercial assumptions before ranking. |
| Commercial comparability risk | Ranking by raw unit price from mixed quote contexts | Incorrect supplier selection and hidden lifecycle cost | Force one template for duty, evidence, Incoterms, and acceptance criteria. |
| Trade-control non-compliance risk | US-bound supply chain selected without UFLPA due-diligence evidence for origin and entity exposure | Entry denial, shipment holds, and high requalification cost | Introduce a compliance gate before award: origin chain evidence, entity screening, and legal review sign-off. |
| Classification drift risk | HS mapping changes after quote comparison or after supplier lock | Duty mismatch, delayed customs clearance, and distorted TCO | Freeze preliminary code mapping pre-RFQ and revalidate before PO release. |
| Integration-overconfidence risk | Using quick checker output as final release approval | Late-stage integration failures | Keep thermal, life, controls, and integration validation as mandatory release gates. |
| Backlash degradation risk | Selecting a standard 2-stage planetary 100:1 gearbox for a high-reversing servo application | Rapid wear, loss of precision (<5 arcmin degrades quickly), and positioning errors | For high-reversing loads, mandate a harmonic drive or a specialized low-backlash planetary design with pre-loaded gears. |
Missing evidence is kept explicit so decisions can move forward with controlled uncertainty instead of hidden assumptions.
| Topic | Current Status | Why Uncertain | Minimum Next Step |
|---|---|---|---|
| Cross-supplier normalized lifecycle cost at 100:1 under one duty profile | 待确认 / 暂无可靠公开数据（截至 2026-05-21） | Public pages rarely disclose complete lifecycle assumptions and transaction-normalized cost structure in comparable format. | Collect at least 3 to 5 supplier RFQs using one unified lifecycle-cost worksheet. |
| Open-data parity for sample pass-rate by quality-pack level | 待确认 / 暂无可靠公开数据（截至 2026-05-21） | Published marketing and catalog data usually omit statistically comparable sample-yield records. | Require sample-acceptance criteria and historical yield disclosures in RFQ annex. |
| Public, machine-readable mapping between gearbox-scope cert validity and process-level CSR conformance | 待确认 / 暂无可靠公开数据（截至 2026-05-21） | Public verification services confirm certificate existence/status, but process-scope-to-project-fit mapping is usually not transaction-ready. | Add supplier self-declaration plus third-party audit evidence aligned to project-specific process scope. |
| Public line-level dataset that links gearbox HS subclasses to real-time duty/exclusion outcomes across destinations | 待确认 / 暂无可靠公开数据（截至 2026-05-21） | Official policy pages publish rules and notices, but not one normalized open dataset for transaction-ready landed-cost benchmarking. | Maintain an internal policy register with dated HTS/CN mapping and destination-specific duty assumptions per RFQ round. |
| Exact dynamic efficiency at 100:1 load | 待确认 / 暂无可靠公开数据（截至 2026-09-25） | Efficiency for a 100:1 planetary gearbox is typically listed generically as >90%, while harmonic drives may be 70-80%, but real-world dynamic efficiency depends heavily on lubrication viscosity and operating temperature. | Request temperature-dependent efficiency curves from shortlisted suppliers. |
These constructed examples show how the page’s screening rules behave. They are not customer cases, field validation, or proof of supplier performance.
| Scenario | Premise | Process | Outcome |
|---|---|---|---|
| Automation integrator with 100:1, <=8 arcmin, PPAP-lite requirement | Mid-volume industrial project, moderate schedule pressure, quality evidence required before release. | Tool selects precision-OEM path and returns review due evidence + schedule pressure intersection. | Team expands shortlist to 4 suppliers and prevents premature price-only lock. |
| Safety-critical deployment with full-trace requirement | Program needs strict quality governance and deeper documentation chain. | Tool routes to program-OEM path and raises no-go if certification assumptions mismatch. | Project avoids non-compliant shortlist and reduces late audit rework risk. |
| Legacy RFQ with ratio drift to 130:1 | Original keyword intent 100:1, but requirement shifted during detail design. | Tool enforces boundary review and blocks strict-go interpretation. | Procurement re-aligns architecture before issuing supplier ranking request. |
These are constructed examples generated by the page’s heuristic model, not anonymized customer records or empirical validation. Outputs are reproducible from the stated constraints.
| Case | Input Snapshot | Directional Model Output | Suggested Next Step |
|---|---|---|---|
| Example A: 100:1 with PPAP-lite requirement | Ratio 100:1, 420 Nm, backlash 8 arcmin, 1,200 units/year, lead time 8 weeks, sample 5 weeks, PPAP-lite, ISO 9001, semi-custom, precision-servo risk. | Preliminary-screen go, precision-OEM assumptions, directional score 84/100 (rounded from 83.6), suggested shortlist size 3. | Suggested next step: issue a normalized RFQ with one shared evidence template before any award decision. |
| Example B: ratio drift to 130:1 during RFQ prep | Same baseline constraints, but target ratio moved from 100:1 to 130:1. | Review boundary triggered because 130:1 is outside strict 90-110 decision band. | Suggested next step: reopen architecture assumptions before supplier ranking. |
Why does this page put the tool before long-form explanation?
Because the query has immediate action intent. You should get a shortlist signal first, then read evidence and boundaries before RFQ lock.
Can I use this checker for any gearbox ratio?
No. This heuristic screen is intended for 100:1-centered sourcing decisions. It uses a strict 90-110 review band inside a broader 40-220 directional range.
What does review status usually mean?
It means one or more constraints are feasible but not yet evidence-complete. You should gather additional quality and delivery proof before ranking suppliers.
What does no-go mean in this tool?
It signals high mismatch between constraints and current supplier path assumptions. Change path or constraints before issuing final RFQ ranking.
When should I escalate from catalog path to precision/program path?
Escalate when backlash target tightens, quality evidence depth increases, or certification/compliance constraints become strict.
Why is quality-pack depth treated as a separate decision axis?
Two suppliers can quote similar specs but deliver very different evidence quality. Without normalized evidence depth, comparison quality is weak.
If I need IATF-level governance, can I still treat catalog-only quotes as go?
No. This page treats that as a hard mismatch and returns no-go until sourcing path and certification assumptions are aligned.
Does a higher directional screen score guarantee success?
No. It improves early decision quality but does not replace integration, life, thermal, and compliance validation.
How many suppliers should I include in shortlist?
Use 3 for go, 4 for review, and 5 for no-go states to reduce single-source bias and evidence gaps.
What should I normalize in RFQ templates?
Normalize duty profile, backlash target, acceptance criteria, quality evidence package, Incoterms, and timeline assumptions across all suppliers.
Can this page replace full procurement engineering review?
No. It is a gate-0 and gate-1 decision aid. Final release still requires full engineering and quality sign-off.
What if I already have one preferred supplier?
Run at least one benchmark comparison round anyway. Even strong incumbents should be validated under the same normalized checklist.
