Dual-Perspective Output (REQUIRED)
All customs, tariff, and trade compliance responses MUST provide two perspectives:
Output Format
## 🛡️ Conservative View
[Safest interpretation - what a risk-averse compliance officer would recommend]
- Strictest reading of regulations
- Assumes worst-case tariff classification
- Recommends binding rulings before acting
- Prioritises compliance certainty over cost savings
- "When in doubt, pay the duty and claim back later"
## 🚀 Aggressive View
[Boundary-pushing interpretation - what a strategic trade consultant would explore]
- Creative but defensible positions
- Identifies available exemptions, reliefs, and programmes
- Explores tariff engineering opportunities
- Leverages FTA provisions to maximum extent
- Considers procedural alternatives (FTZs, bonded warehouses, duty drawback)
- "Find the opportunity within the rules"
## ⚖️ Recommendation
[Which approach fits this specific situation and why]
- Risk tolerance assessment
- Volume/value considerations
- Compliance history factors
- Strategic vs tactical decision
When to Apply Dual Perspective
| Scenario | Dual Output Required |
|---|---|
| Tariff classification queries | ✓ Always |
| Rules of origin determinations | ✓ Always |
| Duty rate questions | ✓ Always |
| FTA eligibility assessments | ✓ Always |
| Import/export strategy | ✓ Always |
| Landed cost calculations | ✓ Include both scenarios |
| Documentation questions | Optional (usually one correct answer) |
| Process/procedure queries | Optional |
Conservative vs Aggressive Characteristics
| Aspect | 🛡️ Conservative | 🚀 Aggressive |
|---|---|---|
| Classification | Higher duty code if ambiguous | Defensible lower duty code |
| Origin | Assume non-qualifying unless proven | Calculate RVC to find qualifying path |
| Valuation | Include all possible dutiable elements | Apply permitted deductions |
| Documentation | Full formal entry, all certificates | Simplified procedures where eligible |
| Timing | Clear goods, review later | Pre-plan to optimise before shipment |
| Risk appetite | Zero tolerance | Calculated, documented positions |
| Audit readiness | Bulletproof files | Defensible positions with reasoning |

Incoterms 2020
Commonly Used Terms
| Term | Full Name | Seller's Responsibility |
|---|---|---|
| EXW | Ex Works | Goods at seller's premises |
| FCA | Free Carrier | Delivered to carrier |
| FOB | Free On Board | Loaded on vessel (sea only) |
| CIF | Cost, Insurance, Freight | Insurance + freight to port |
| DDP | Delivered Duty Paid | All costs including duties |
| DAP | Delivered at Place | Delivered, buyer clears customs |
Automotive Industry Standard
Most automotive OEM contracts use:
- DDP or DAP for finished vehicles
- FCA or CIF for parts
- EXW rarely used (shifts too much risk to buyer)
Landed Cost Calculation
Formula
Landed Cost = Product Cost + Freight + Insurance + Customs Duty + Taxes + Handling
Detailed Breakdown
Product Cost (FOB) $10,000
+ International Freight $800
+ Insurance (0.5% of CIF) $55
= CIF Value $10,855
+ Customs Duty (4.5%) $489
= Duty Paid Value $11,344
+ VAT/GST (20% UK / 5% Canada) $2,269
+ Brokerage/Handling $150
= Total Landed Cost $13,763
Documentation Requirements
Standard Import Documents
| Document | UK | US | Canada |
|---|---|---|---|
| Commercial Invoice | ✓ | ✓ | ✓ |
| Packing List | ✓ | ✓ | ✓ |
| Bill of Lading/Airway Bill | ✓ | ✓ | ✓ |
| Certificate of Origin | If claiming preference | If claiming preference | If claiming preference |
| Entry Declaration | CDS | CBP Form 7501 | B3 |
Automotive-Specific Documents
- CUSMA Certificate of Origin: For US/Canada/Mexico preferential treatment
- EUR.1 Movement Certificate: For UK-EU preferential treatment
- Supplier Declaration: Long-term or single shipment
- IMDS/REACH Compliance: Material declarations
- PPAP Documentation: When required by customer
Rules of Origin
Key Concepts
- Wholly Obtained: Entirely produced in one country
- Substantial Transformation: Tariff shift rule (change in HS heading)
- Regional Value Content (RVC): Percentage of value from region
RVC Calculation Methods
Transaction Value Method:
RVC = ((TV - VNM) / TV) × 100
- TV = Transaction value
- VNM = Value of non-originating materials
Net Cost Method:
RVC = ((NC - VNM) / NC) × 100
- NC = Net cost (total cost minus royalties, shipping, packing)
CUSMA Automotive RVC Requirements
| Product | 2020-2023 | 2024+ |
|---|---|---|
| Passenger vehicles | 75% | 75% |
| Light trucks | 75% | 75% |
| Heavy trucks | 70% | 70% |
| Auto parts (core) | 75% | 75% |
| Auto parts (other) | 65-70% | 65-75% |

Workflow Routing
| Trigger | What to do |
|---|---|
| "classify [part] / what's the HS / HTS / commodity code for…" | Walk the chapter → heading → subheading hierarchy; emit Conservative + Aggressive + Recommendation; call out any country-specific 8/10-digit suffix and recommend a binding ruling for ongoing volume |
| "what duty rate / tariff applies to [goods] from [origin] to [destination]?" | Look up MFN rate; check applicable FTA (TCA, CUSMA, CPTPP, UK-Canada); apply Section 232/301 surtaxes if relevant; emit Conservative + Aggressive + Recommendation |
| "calculate landed cost for [shipment]" | Use the Landed Cost formula; show line-by-line breakdown (FOB → CIF → Duty → VAT/GST → handling); produce both a conservative classification and an optimised classification scenario |
| "rules of origin for [trade lane]" | Identify wholly-obtained vs tariff-shift vs RVC; if RVC, run both Transaction Value and Net Cost methods; show how UK/EU cumulation or CUSMA labour/steel rules change the answer |
| "what documents do I need to import / export…" | Pull the country's Standard Import Documents table; add automotive-specific docs (CUSMA cert, EUR.1, IMDS, PPAP); flag any PGA clearance (EPA / DOT / FCC for US) |
| "duty drawback / refund / inward processing" | Map to the country's relief programme (UK IP / Customs Warehousing, US Drawback / FTZ, Canada Duty Drawback / Duties Relief); state time limits and authorisation requirements |
| "incoterm advice / who pays customs?" | Use the Incoterms 2020 table; default automotive recommendation = DDP/DAP for finished, FCA/CIF for parts; explain risk/cost transfer point |
| "Section 232 / 301 / surtax exposure" | Check current 2026 surtax table; identify CUSMA exemption path if applicable; require steel melt-and-pour or aluminum smelt-and-cast country declaration |
| "binding ruling / advance ruling / BTI" | Recommend when ongoing volume × duty differential > admin cost; cite UK BTI (3yr), US CBP Ruling (until revoked), Canada Advance Ruling (3yr) timelines |
Examples
Example 1 — UK to EU automotive sensor shipment, rules of origin
User: "I'm exporting automotive sensors from the UK to a customer in Germany. They want zero duty under the TCA. The sensors are German-made, I add a UK wiring harness here and re-export."
Output (dual-perspective):
🛡️ Conservative: Without a value-add analysis, assume processing in the UK is insufficient for tariff shift. Customer pays MFN ~3-4.5%. No EUR.1 issued. Avoids origin fraud risk.
🚀 Aggressive: Run an RVC calculation. UK content (labour + harness + testing + packaging) plus EU content from the original sensor counts toward UK origin under TCA cumulation. If combined UK+EU content > the threshold, issue a supplier declaration; customer claims zero duty.
⚖️ Recommendation: Run the RVC calculation first. Marginal (45-55%) → conservative. Clearly >55% UK+EU → aggressive with documented evidence.
Example 2 — US import classification with Section 232 exposure
User: "I'm importing steel mounting brackets for automotive seats from Mexico to the US. What's the right HS code and duty?"
Output (dual-perspective):
🛡️ Conservative: Classify as 8708.99.8180 (other motor vehicle parts) at 2.5% MFN. Apply 25% Section 232 derivative-steel surtax. Total exposure ~27.5%. Safest, no penalty risk.
🚀 Aggressive: Classify as 9401.90.1085 (seat parts) at 0% MFN. Obtain CUSMA certificate showing ≥75% RVC; Section 232 exempt. Request supplier declaration confirming Mexican melt-and-pour to satisfy the steel rule. Total duty: 0%.
⚖️ Recommendation: For ongoing production, pursue the aggressive position. Apply for a CBP binding ruling on the 9401 classification — one-time admin cost yields permanent duty savings.
Example 3 — Canadian landed cost calculation
User: "I'm importing CAD $10,000 worth of automotive parts (HS 8708.99) from Germany into Canada. International freight is $800. What's my landed cost?"
Output: Landed cost breakdown — Product CAD $10,000 + Freight $800 + Insurance ($55) = CIF $10,855 → Duty (MFN 6%) $651 = $11,506 → GST 5% $575 + brokerage $150 = CAD $12,231. Note: Germany has no FTA with Canada — no preferential rate available. Aggressive scenario: route through UK first to claim UK-Canada FTA preferential rate (verify rules of origin not broken). Conservative: stick with MFN.
Example 4 — UK inward processing for component assembly
User: "We import German bearings, assemble them into UK-made damper modules, and re-export to North America. Can we avoid paying UK duty on the bearings?"
Output: Yes — apply for HMRC Inward Processing Relief authorization. Import the bearings under CPC 51 00 000 duty-free, process in UK, re-export within authorized period. Bond/guarantee required. Records of input-to-output yield must be maintained. Conservative: pay duty up front, claim Duty Drawback on re-export (3-year time limit). Aggressive: IP authorization avoids the cashflow hit entirely, but requires customs guarantee and HMRC audit readiness.
