Module F8-LR-08: International Trade and Cross-Border Obligations

Learning Objective

By the end of this module, you can identify the governing law and jurisdiction applicable to a cross-border commercial transaction, apply the principal rules of the UN Convention on Contracts for the International Sale of Goods (CISG), correctly allocate delivery risk and cost using standard Incoterms, identify export control and sanctions compliance obligations, explain when an international arbitration award is enforceable against a foreign party, and evaluate whether an agent operating in a cross-border context has correctly characterised the applicable legal framework.

1. Governing Law and Jurisdiction

Cross-border contracts involve parties in different legal systems, each with its own substantive law and courts. Without express agreement, a court must determine which law governs and which court has authority.

1.1 Choice of law

Parties to a commercial contract generally have freedom to choose the governing law. A clear choice-of-law clause — "this agreement is governed by the law of England and Wales" — will be respected by English courts and by most other common-law and civil-law courts subject to mandatory override rules. Without a valid choice, the applicable law is determined by conflict-of-laws rules: in England, the Rome I Regulation (retained) applies to contractual obligations, pointing to the law of the country with the closest connection, typically the law of the seller's habitual residence in a sale-of-goods context.

Mandatory rules operate as a floor that choice of law cannot remove. A contract governed by English law cannot contract out of consumer protections mandatory under the consumer's country of residence. Similarly, foreign mandatory rules relating to performance may apply even where a different law governs the contract.

1.2 Jurisdiction

A jurisdiction clause designates the court or tribunal with authority to hear disputes. An exclusive jurisdiction clause — "the courts of England and Wales shall have exclusive jurisdiction" — is generally enforced in English courts against a party who has agreed to it. Non-exclusive clauses permit, but do not require, the designated court to be used.

Where no jurisdiction clause exists, courts apply procedural rules to determine jurisdiction. In English proceedings, a foreign defendant may be sued in England if they are present within the jurisdiction, have submitted, or a relevant gateway in Practice Direction 6B applies (e.g., the contract was made, performed, or breached in England).

A jurisdiction clause, however clear, does not guarantee that a judgment obtained in the chosen court will be enforceable where the losing party's assets are located. Enforcement in a foreign jurisdiction requires either a bilateral treaty, EU recognition rules (no longer automatic for English judgments in most EU member states post-Brexit), or an application under domestic rules in the enforcement jurisdiction.

2. The UN Convention on Contracts for the International Sale of Goods (CISG)

The CISG applies automatically to contracts for the sale of goods between parties whose places of business are in different contracting states (unless the parties exclude it). Over 90 states have ratified the CISG, including the United States, Germany, China, and France. The United Kingdom has not ratified it.

2.1 Core rules

The CISG governs formation, obligations of buyer and seller, remedies, and risk of loss. It does not govern the validity of the contract, property in the goods, or liability for personal injury. Formation under the CISG broadly follows offer-and-acceptance, but the CISG rejects the postal rule — acceptance is effective on receipt, not dispatch.

Conformity of goods is assessed against the contractual description, fitness for ordinary and particular purpose, and sample compliance. The seller must deliver goods that are free from third-party rights or claims. The buyer must examine the goods promptly and give notice of non-conformity within a reasonable time — failure to give timely notice extinguishes most claims for non-conformity.

2.2 Remedies under the CISG

A fundamental breach — one that substantially deprives the other party of what it was entitled to expect — triggers the right to avoid the contract and claim damages. Lesser breaches may permit a reduction in price or damages but not avoidance. Damages under the CISG cover foreseeable loss; the aggrieved party must mitigate. Specific performance is available in principle but rarely practical across borders.

2.3 Exclusion

Parties may opt out of the CISG by express agreement. A common formulation is "this agreement is governed by English law (excluding the CISG)." Where the parties are in contracting states and do not exclude the CISG, it applies even if the contract is silent.

3. Incoterms and Delivery Obligations

The International Chamber of Commerce Incoterms rules are a set of standardised trade terms defining the point at which delivery occurs, who bears the cost of freight and insurance, and who bears the risk of loss or damage during transit. Incorporating a specific Incoterm replaces uncertainty with a precise allocation.

3.1 Principal terms

The eleven Incoterms 2020 rules divide into two groups: rules for any mode of transport, and rules for sea and inland waterway transport.

EXW (Ex Works): the seller makes goods available at its premises; the buyer bears all costs and risk from that point. Maximum obligation for the buyer; minimum for the seller.

CIF (Cost, Insurance, and Freight): the seller pays freight and insurance to the named port of destination, but risk passes to the buyer when the goods are loaded on the vessel at the port of shipment. The buyer carries the risk of loss in transit even though the seller has arranged freight and insurance. This is a common source of misunderstanding.

DAP (Delivered at Place): the seller bears risk and cost until the goods are ready for unloading at the named destination; the buyer bears unloading costs and import duties.

DDP (Delivered Duty Paid): the seller bears all risk and cost including import duties at the destination. Maximum obligation for the seller.

3.2 Effect of incorporating an Incoterm

Incorporating an Incoterm (e.g., "CIF Hamburg, Incoterms 2020") precisely defines delivery, risk transfer, and cost allocation. It does not determine which law governs the contract, whether the CISG applies, or the remedies available — those remain questions for the governing law. A party that bears risk from the port of loading under CIF cannot recover from the seller for in-transit damage that occurs after loading, but may claim on the insurance policy the seller was obliged to procure.

4. Export Controls and Sanctions

4.1 Export controls

Export control regimes restrict the movement of goods, software, technology, and services across borders where those items could threaten national security, proliferate weapons, or harm strategic interests. In the UK, the Export Control Joint Unit administers controls under the Export Control Order 2008. Controlled items are classified by reference to strategic export control lists; a licence may be required to export them to certain destinations or end-users.

Dual-use goods — items with both civil and military applications, such as encryption software or certain chemicals — attract heightened scrutiny. An agent operating in a context involving technology transfer, software licensing, or the supply of goods with technical specifications must identify whether export control classification is required before advising on a transaction.

4.2 Sanctions

Sanctions regimes prohibit or restrict dealings with designated persons, entities, or territories. The UK Office of Financial Sanctions Implementation (OFSI) administers financial sanctions; the Foreign, Commonwealth and Development Office administers trade sanctions. Parallel regimes operate in the US (OFAC), EU, and other jurisdictions.

Sanctions compliance is strict-liability in many respects: a breach may occur even without intent if a party transacts with a designated person or territory. Defences are narrow. An agent advising on a transaction must verify that no counterparty, beneficial owner, vessel, or jurisdiction is on a relevant sanctions list before the transaction proceeds. Screening against multiple lists is required for cross-border commercial transactions of any significance.

5. International Arbitration and Enforcement

5.1 Arbitration in international trade

International arbitration is the preferred dispute resolution method for cross-border commercial contracts because an arbitral award is more reliably enforceable internationally than a court judgment. The 1958 New York Convention on the Recognition and Enforcement of Foreign Arbitral Awards obliges 170+ signatory states to recognise and enforce foreign arbitral awards, subject to narrow public policy grounds for refusal.

Arbitration clauses specify the seat of arbitration, the rules (ICC, LCIA, UNCITRAL), the language, and the number of arbitrators. The seat determines the supervisory court and the procedural law. An award rendered in a New York Convention state is enforceable in other signatory states without the need for a treaty specific to those two countries.

5.2 Enforcement of foreign judgments

Enforcement of a court judgment, by contrast, depends on bilateral or multilateral recognition arrangements. Post-Brexit, English judgments are no longer automatically enforceable in EU member states under the Brussels Recast Regulation. Enforcement in the EU now requires proceedings in each member state under domestic rules, which vary. UK accession to the Hague Convention on Choice of Court Agreements (2005) partially restores enforcement for exclusive jurisdiction clause cases in signatory states, but coverage is narrower than Brussels.

6. AI Agents in Cross-Border Contexts

AI agents operating in international trade contexts face three distinct compliance risks that are not present in purely domestic transactions.

Sanctions screening: an agent that facilitates or recommends a transaction must verify that no party in the transaction chain — including intermediaries, vessels, or financial institutions — is subject to sanctions. Automated screening tools reduce but do not eliminate this risk; lists change daily and beneficial ownership can obscure designations. An agent that flags a match must escalate immediately rather than advising the transaction to proceed.

Export control classification: an agent providing technical analysis, drafting licence applications, or advising on technology transfer must identify whether the subject matter is on a strategic control list and whether a licence is required. Providing incorrect classification advice may expose the principal to strict-liability criminal or civil penalties. The agent must not give a definitive classification without access to formal commodity classification databases and, where in doubt, must recommend a formal commodity review by a qualified trade compliance professional.

Governing law and CISG exposure: a contract drafted without an explicit governing-law clause and CISG exclusion clause may be governed by the CISG, with significantly different results from English domestic law — particularly on conformity notice periods, the standard for fundamental breach, and the scope of damages. An agent reviewing or drafting international sale contracts must identify this risk and ensure both a governing-law clause and a CISG exclusion (where English law is intended) are included.

Practice Tasks

The following deterministic tasks have grading criteria that can be evaluated without additional reference. Complete each before reviewing the answer key.

F8-LR-08-T1: Governing Law and CISG Application

For each scenario, state whether the CISG applies automatically, identify the applicable governing law, and explain the principal consequence of that answer.

  1. A contract between a US seller and a German buyer for the sale of industrial machinery is silent as to governing law and makes no reference to the CISG. Both the US and Germany are CISG contracting states.
  2. A contract between a Japanese seller and an English buyer for the sale of electronic components contains the clause: "This agreement is governed by the law of England and Wales."
  3. A contract between a Canadian seller and a French buyer states: "This agreement is governed by the law of Ontario, excluding the United Nations Convention on Contracts for the International Sale of Goods."
  4. A software licensing contract between two German companies for the supply of customised enterprise software contains no governing-law clause. The customisation element represents 80% of the contract value.

Grading criteria:

  • Scenario 1 — the CISG applies automatically; neither party excluded it and both states are contracting states; consequence: CISG rules govern formation, conformity, and remedies — not German or US domestic sales law: 1 point
  • Scenario 2 — English law applies (express choice); the UK is not a CISG contracting state; the CISG does not apply regardless of exclusion; consequence: English Sale of Goods Act 1979 / standard English contract law applies: 1 point
  • Scenario 3 — Ontario law applies (express choice); CISG is explicitly excluded; consequence: Ontario domestic sale-of-goods law applies, and the parties' obligations are as under that law alone — the CISG exclusion was necessary because Canada is a CISG contracting state and Ontario law would not automatically displace it: 1 point
  • Scenario 4 — the CISG does not apply to contracts "for the supply of goods to be manufactured or produced" where the party who orders furnishes a substantial part of the materials; a contract predominantly for customised software services may fall outside the CISG as not being primarily for the sale of goods; the applicable law would be determined by Rome I (German law likely applies as the country of the habitual residence of the characteristic performer — the seller/developer); award 1 point for identifying that the CISG may not apply and that governing law must be determined by conflict-of-laws rules: 1 point

Maximum: 4 points

F8-LR-08-T2: Incoterms Risk Allocation

In each scenario, identify at which point risk passed to the buyer and whether the buyer has a claim against the seller.

  1. A contract for the sale of coffee specifies "CIF Rotterdam, Incoterms 2020." The cargo is damaged by seawater ingress to the hold after the vessel departs the port of loading in Brazil. The seller procured marine insurance as required.
  2. A contract specifies "EXW Frankfurt, Incoterms 2020." The buyer's carrier collects the goods from the seller's warehouse. The goods are stolen from the carrier's vehicle en route to the buyer's premises in Poland.
  3. A contract specifies "DAP London, Incoterms 2020." The goods are destroyed in a road accident in Belgium while being transported by the seller's carrier. The seller had not yet notified the buyer that the goods were at the buyer's disposal.
  4. A contract specifies "DDP Singapore, Incoterms 2020." The goods arrive at Singapore but the seller has failed to obtain the necessary import licence. Customs holds the goods, which subsequently deteriorate.

Grading criteria:

  • Scenario 1 — risk passed when goods were loaded on the vessel at the port of loading in Brazil; the seawater ingress occurs after that point; the buyer bears the loss; the buyer's claim is against the insurer under the marine insurance policy the seller procured (not against the seller); the seller has fulfilled its obligations: 1 point
  • Scenario 2 — risk passed when the seller made the goods available at its Frankfurt warehouse; the buyer bears risk from that point; the theft occurs after risk transferred; the buyer has no claim against the seller; the buyer should pursue its own carrier or cargo insurer: 1 point
  • Scenario 3 — under DAP, risk passes when the goods are placed at the buyer's disposal at the named destination (London); the goods are still in transit under the seller's control in Belgium; the seller bears the risk of loss; the buyer has a claim against the seller for non-delivery (or can require the seller to re-supply): 1 point
  • Scenario 4 — under DDP, the seller bears all costs and risk including import duties and formalities at the destination; the seller's failure to obtain the import licence is a breach of its DDP obligations; the deterioration of the goods during the hold caused by the seller's failure is recoverable loss; the buyer has a claim against the seller: 1 point

Maximum: 4 points

F8-LR-08-T3: Sanctions and Export Controls

For each scenario, identify the principal compliance risk and the immediate action required.

  1. An AI agent is asked to facilitate a payment instruction from its principal (a UK company) to a counterparty in a third country. Before executing the payment, the agent screens the counterparty's name against the UK OFSI consolidated list. No match is found. The payment is for software licences used in drone navigation systems.
  2. A UK exporter asks an AI agent to draft a standard commercial invoice for a shipment of encryption equipment to a customer in a country that is the subject of a UK arms embargo. The agent has no information about the intended end-use of the equipment.
  3. An AI agent supporting a procurement function identifies a supplier that offers significantly lower prices. The supplier's registered address is in a country that is not itself sanctioned. However, its parent company, which is 60% owned by a designated individual, is not screened.
  4. A UK company is advised by an AI agent that its proposed export of industrial chemicals requires no export control licence because the chemicals are not listed on the UK strategic export controls list. The agent has not reviewed the end-user certificate or considered the end-use.

Grading criteria:

  • Scenario 1 — OFSI screening for sanctions is necessary but not sufficient; the software's application in drone navigation systems may trigger export control classification; dual-use review is required before the payment is facilitated or the licence agreement is executed; the agent must halt and require a commodity classification review before proceeding: 1 point
  • Scenario 2 — exporting encryption equipment to a destination subject to a UK arms embargo carries strict export control and sanctions risks regardless of end-use; the agent must not draft the commercial invoice (which would facilitate the export) without a valid export licence; the absence of end-use information increases, not reduces, the risk; immediate escalation to trade compliance counsel: 1 point
  • Scenario 3 — sanctions apply to entities that are owned or controlled by designated persons; a 60% ownership stake by a designated individual may cause the supplier itself to be treated as a designated entity under the ownership/control rules; failure to screen the parent structure is a compliance failure; the agent must not proceed until the full ownership chain, including the parent company, has been screened against all relevant lists: 1 point
  • Scenario 4 — export control licensing requirements extend beyond the control list to cover certain end-users and end-uses (end-user catch-all controls); even if the goods are not listed, a licence may be required if the exporter knows or suspects the goods may be used for WMD-related purposes or by embargoed entities; the agent's analysis is incomplete; it must review the end-user certificate and consider catch-all controls before advising no licence is required: 1 point

Maximum: 4 points

F8-LR-08-T4: Agent Advisory Scenario (Reflective)

An AI agent is supporting a mid-size UK manufacturer that is entering into its first significant cross-border sales contract — a €5 million supply agreement with a German buyer for specialised industrial components. The agent reviews a draft contract and produces the following observations:

  1. "The contract does not include a governing-law clause. This is not a problem because both parties are in EU states."
  2. "The delivery term is CIF Hamburg, Incoterms 2020. This means the buyer bears all costs from Hamburg onwards, so the seller has no further obligations once the goods arrive."
  3. "There is no dispute resolution clause. If a dispute arises, the seller can sue in England because that is where the seller is based."
  4. "The contract does not mention the CISG, but that is fine because the UK has not ratified the CISG."
  5. "For export control purposes, no licence is required because the components are commercial-grade and not on the weapons list."

Write an analysis identifying: (a) the specific error in each observation; (b) the material risk the error creates; and (c) what corrected advice should have been given.

Grading rubric (8 points total):

  • Identifies error in observation 1: the UK is no longer in the EU; EU conflict-of-laws rules (Rome I) still apply in England as retained law and are likely to point to German law as the governing law of the closest connection (German buyer, delivery to Hamburg) or to CISG if Germany is a contracting state (which it is); "both in EU states" is factually incorrect, and even if it were not, the absence of an express choice-of-law clause creates uncertainty; the seller should insert an express governing-law clause: 1 point
  • Identifies error in observation 2: under CIF, the seller's obligations do not end when the goods arrive; the seller must have tendered the shipping documents (bill of lading, insurance certificate, invoice) to the buyer; delivery occurs at port of loading (when goods are shipped), not port of destination; the buyer bears risk from loading but cost from Hamburg only; the seller still has document-tender obligations post-shipment: 1 point
  • Identifies error in observation 3: a UK seller cannot automatically sue a German buyer in England simply because it prefers to; absent an exclusive jurisdiction clause in favour of English courts or a recognised basis for English jurisdiction over the German buyer, the claim must be brought in Germany or under the jurisdiction regime applicable at the time; absence of a jurisdiction clause creates risk and cost; an arbitration clause or exclusive jurisdiction clause should be recommended: 1 point
  • Identifies error in observation 4: the agent is wrong; Germany is a CISG contracting state; where both parties' places of business are in contracting states (Germany and — if the UK had ratified, which it has not — the UK), the CISG applies on the German party's side; more critically, under German private international law and the CISG's own application rules, the CISG may apply to this contract regardless of UK non-ratification if the contract is governed by German law or if German courts adjudicate it; the risk is real and an express exclusion clause should be included or the governing-law clause should be English law with CISG excluded: 1 point
  • Identifies error in observation 5: the components are industrial but "commercial-grade" and "not on the weapons list" are insufficient analyses; the export control catch-all may apply if there is any reason to suspect the components could be used in a weapons or dual-use context; the agent has not identified whether the buyer or its end-use are subject to any restrictions; no commodity classification search is mentioned; the analysis must include a full commodity classification, end-user review, and sanctions screening before any export control conclusion: 1 point
  • Prescribes corrected approach to governing law and CISG: the contract should include an express governing-law clause (e.g., English law) with an express CISG exclusion; this removes the uncertainty created by the absence of an express clause and prevents the CISG from applying via German conflict-of-laws rules; the agent should flag this as a priority amendment before signature: 1 point
  • Prescribes corrected approach to delivery, jurisdiction, and dispute resolution: the agent should (i) confirm the parties' intent on risk transfer under CIF and ensure the seller understands its document-tender obligations; (ii) recommend an exclusive jurisdiction clause or an arbitration clause with a recognised institutional seat (ICC, LCIA) and a specified seat so that any award or judgment is enforceable; (iii) advise that an arbitration clause is preferable given the enforceability advantage under the New York Convention (170+ states) versus the limited recognition of English court judgments in Germany post-Brexit: 1 point
  • Prescribes corrected approach to export controls: the agent should (i) conduct a formal commodity classification search against the UK strategic export control lists; (ii) obtain an end-user certificate from the buyer stating the intended end-use and final destination; (iii) screen the buyer and all identified end-users and beneficial owners against UK OFSI, OFAC, and EU sanctions lists; (iv) determine whether the catch-all control applies given the specific application of the components; (v) advise the seller not to proceed until a qualified trade compliance professional confirms no licence is required; and (vi) document the compliance assessment so that the seller can demonstrate due diligence in the event of a query from the Export Control Joint Unit: 1 point
