4. International Trade Law: Contracts, CISG, and Remedies
Teaching rewrite of trade-law foundations for exporters and importers. Pedagogical summaries only — not legal advice and not the text of the CISG, ICC rules, or any handbook. For a live deal, read the primary sources and talk to counsel in the relevant jurisdiction.
Introduction
An export sale is never just one contract. Behind a single shipment sit a chain of linked agreements: the sale itself, the carriage contract, the cargo insurance policy, the payment instrument, sometimes an inspection order and a customs broker mandate. Each link is governed by a different body of rules. When the links agree, the deal runs quietly. When one link is silent or contradicts another — the insurance does not cover what the sale promised, the letter of credit asks for a document the carriage contract cannot produce — the gap surfaces at the worst moment: when goods are lost, late, or rejected.
This lesson gives you the legal map an operator needs:
- Which law governs which link of the transaction chain
- Why the sale contract is the “master” and must be complete and written
- How civil law, common law, and Shari’a traditions shape business habits
- Jurisdiction and choice of law — where disputes go and which law decides them
- The CISG (UN sales convention): scope, key rules, and the battle of the forms
- Breach and remedies — and the money logic of whether suing is even worth it
- Pre-contract risk: offers, acceptances, letters of intent, and model contracts
Assumptions. We take the viewpoint of a business-to-business sale of goods across a border. Consumer sales, services-heavy deals, and land or securities transactions follow other rules and are out of scope.
4.1 The legal map of one export deal
Think of the sale contract as the hub and every other contract as a spoke that must conform to it.

| Link | Typical governing rules | What goes wrong |
|---|---|---|
| Sale | National commercial law or the CISG | Missing terms; conflicting forms |
| Delivery / trade terms | Incoterms® (seller ↔ buyer only) | Confusing the sale term with the carriage contract |
| Carriage | Mode-specific transport law and treaties (e.g. Hague / Hague-Visby for sea) | Carrier liability far lower than the cargo value |
| Payment | ICC uniform rules (e.g. UCP 600 for documentary credits) | Credit asks for documents the seller cannot produce |
| Insurance | Under CIF/CIP: seller buys at least minimum cover at contract price + 10% | Minimum cover misses theft or war risks |
| Disputes | Choice-of-law and forum / arbitration clause | No clause → overlapping courts, unknown law |
Example. A buyer opens a letter of credit that requires an “on board” ocean bill of lading plus an inspection certificate. The seller now must book carriage that issues that exact document and hire an inspector — the payment spoke dictates the carriage and inspection spokes. If the sale contract never said which documents the credit may demand, the seller discovers the burden only when the credit arrives.
Published model contracts (for sale, agency, distribution, and so on) are useful even when you never sign one: line up the counterparty’s draft against the model clause by clause and see what is missing or one-sided.
4.2 Complete, precise, written contracts
When anything goes wrong, the parties first reach for the contract. If it is silent or vague, the only remaining tools are expensive and adversarial: litigation or arbitration. A good contract is less a weapon than a record of what both sides understood — most disputes are prevented by the conversation that produced it.
Habits that cause trouble:
- Rushing to sign whatever form the other side presents because the deal “feels done”
- Treating a terse commodity-style confirmation as adequate for a complex manufactured product
- Relying on a handshake and goodwill for terms that matter (inspection periods, warranty, remedies)
- Assuming you have no leverage against a standard form — you can often send back an acceptance that excludes a specific clause
Case snapshot — signing what you cannot read
Paraphrased from a reported U.S. appellate decision (MCC-Marble Ceramic v. Ceramica Nuova d’Agostino, 11th Cir. 1998). A U.S. tile importer agreed price, quantity, and delivery orally with an Italian manufacturer at a trade fair, then signed the maker’s pre-printed form whose terms were written in Italian — a language the buyer could not read. When the buyer later complained about quality without following the form’s notice procedure, the seller relied on the printed terms. The appeal turned on whether evidence of the oral side-understanding could be heard; because the CISG governed (not domestic U.S. contract law), the court allowed it.
Lesson for operators: the buyer only escaped through a long appeal. Never sign terms you have not read in a language you understand; get a translation first.
Oral agreements
Under the CISG, a contract need not be in writing to be valid. Some national laws do require writing, and many contracts contain an entire-agreement / merger clause saying only the written document counts and changes must be written. Even where an oral promise is enforceable, you must prove it — typically through the parties’ conduct, a prior course of dealing between them, or an established trade usage.
4.3 Legal families: civil law, common law, Shari’a
| Family | Where (examples) | Main source of law | Role of the judge |
|---|---|---|---|
| Civil law | France, Germany, Italy, most of continental Europe, Japan, much of Latin America | Comprehensive codes (rooted in Roman law; shaped by the French 1804 and German 1896 codes) | Applies the code; may take an active, investigative role; precedent is persuasive |
| Common law | England, U.S., Canada, Australia, New Zealand, Nigeria | Statutes plus binding precedent | Bound by prior decisions; creates new law for novel cases |
| Shari’a | Many Muslim-majority states (e.g. Saudi Arabia, Iran, Pakistan, Egypt — applied to differing degrees) | Religious sources (Qur’an, Prophetic tradition, scholarly interpretation) | Strong respect for commercial custom; compatible with arbitration |
Why this matters on the desk
- Contracts drafted by U.S. lawyers are famously long: freedom of contract plus a litigious market reward spelling everything out. Civil-law counterparts often find this excessive, because the code supplies default rules.
- In Islamic-law markets, doctrines such as riba (often read as prohibiting interest) shape financing — expect profit-sharing or mark-up structures rather than plain interest-bearing credit.
- Even two common-law systems (U.S. and England) differ on important points. Never assume “same family” means “same rule”.

4.4 Jurisdiction and choice of law
Jurisdiction = a court’s or tribunal’s power to hear a dispute. Without a clause, courts in several countries may each claim it, and each may apply its own conflict-of-laws reasoning. A well-drafted contract answers two separate questions:
a. Which law applies?
Parties are generally free to choose. The stronger party usually pushes its own law. If nothing is chosen, the court or tribunal runs a conflict-of-laws analysis to find the most appropriate law; arbitrators have wider freedom to pick the rules they consider appropriate.
In arbitration there can be two laws: the substantive law of the contract and the procedural law (usually that of the seat). National courts always use their own procedure.
b. Which forum decides?
Options: the national courts of one party, a neutral court, or arbitration (e.g. ICC arbitration). Certain matters — labour disputes, for instance — may be reserved to particular national courts regardless of the clause. If you choose arbitration, specify:
- Applicable (substantive) law
- Seat of arbitration
- Language
- Number of arbitrators (usually 1 or 3)
…and use a recognised model arbitration clause rather than inventing wording.
Why the forum matters so much: foreign litigation means travel, local counsel, translation of documents, and executive time. Securing your home forum can deter the counterparty from suing at all — which is exactly why each side resists the other’s courts.
The Hague Convention on Choice of Court Agreements (2005) supports enforcing exclusive forum clauses and the resulting judgments among its parties. Uptake was very slow at first; it has since entered into force for the EU, Mexico, Singapore, the UK and others. Check current status for the countries in your deal.
4.5 The CISG (UN Convention on Contracts for the International Sale of Goods)
Most national sales laws and the CISG distil centuries of merchant practice — the lex mercatoria — so they share much of their logic. The CISG gives one uniform set of rules for forming and performing international sale contracts and has been adopted by most major trading nations (now well over 90 states).
Critics say it leans toward buyers; supporters say its balance lets parties stop fighting to impose their own domestic law. Either way, every trader should know its outline.
If both parties are in CISG states and the contract says only “governed by New York law”, the CISG still applies — it is part of U.S. (federal) law. To exclude it you must say so expressly, e.g. “the CISG does not apply”.
a. Scope — four limits
- International sales only. It applies when the parties have places of business in different CISG states; or when conflict rules lead to the law of a CISG state; or when parties expressly opt in.
- Excluded sales. Consumer purchases; ships, aircraft, electricity; securities; contracts where services predominate (parties may opt back in).
- Topics it does not cover. Trade terms (it defers to usages such as Incoterms®) and passing of title / property (left to national law).
- Freedom of contract. Parties may exclude the CISG entirely, vary any provision, or use it as the main law with a named national law to fill gaps.
b. Key provisions for operators
| Topic | CISG default (paraphrased) | Exporter’s drafting move |
|---|---|---|
| Form | Oral contracts are valid; no signed writing needed | Add an entire-agreement clause and require written modifications |
| Usages & course of dealing | Parties are bound by agreed usages and their own established practices; courts increasingly treat Incoterms® as such a usage | Still cite the Incoterm and edition expressly |
| Offer | Must be sufficiently definite: identifies goods and fixes (or provides a way to fix) quantity and price | Mark price lists “not an offer” if you do not intend to be bound |
| Acceptance | Effective when it reaches the offeror; offer can no longer be revoked once acceptance is dispatched | Track acceptance dates; set validity periods |
| Battle of the forms | An acceptance with material changes (price, quantity, quality, delivery, payment, liability, disputes) = rejection + counter-offer; non-material changes form a contract unless promptly objected to | Send your own acknowledgement with your conditions — aim to “fire the last shot”; negotiate openly on any clause you truly cannot accept |
| Delivery & risk | Covered more thinly than Incoterms® | Incorporate the Incoterm explicitly |
| Documents & L/Cs | Banks under UCP 600 deal in documents, not goods | Reference UCP 600 in the clause describing the seller’s document duties |
| Title | Not covered (nor by Incoterms®) | State when title passes (e.g. retention until paid) and check local enforceability |
| Conformity / warranty | Goods must match the contract in quantity, quality, description, and be fit for ordinary purposes and for any particular purpose made known to the seller | Define specs and limit implied warranties where the law allows |
| Inspection & notice | Buyer must examine promptly and give notice of non-conformity within a reasonable time or lose the claim | Fix a short, concrete notice period; shift the risk of lost notices (overriding the CISG default that the sender is protected) |

4.6 Performance, breach, and remedies
Most contracts are performed well enough, and small slips get forgiven. That comfort is dangerous: the clauses matter for the rare serious breach, and sloppy habits in good years become evidence of waiver in bad ones.
Curing and waiver. Some breaches are curable — a seller who delivers non-conforming goods early may still deliver conforming goods before the deadline. Forgiving a minor breach (goods a day late) is common, but forgiving it repeatedly can be read as a waiver of the right. Two protections:
- A clause that changes to rights must be in a signed writing (not enforceable everywhere)
- Objecting in writing to small breaches, even when you accept the goods, so a paper trail shows you did not waive
a. What determines the remedy
- The contract — e.g. a liquidated-damages clause fixing compensation for late delivery
- The applicable law — common-law courts are more reluctant than civil-law courts to order specific performance
- The gravity of the breach
- Substantial performance: the bulk was performed and the shortfall is minor → usually only a price reduction
- Fundamental breach: the breach deprives the other side of what it essentially bargained for → it may terminate (avoid) the contract
b. Remedies menu
| Remedy | Idea | Watch-outs |
|---|---|---|
| Money damages | Compensation for the loss; may take the form of a price reduction or lump sum | Must be proven |
| Consequential damages | Foreseeable knock-on losses (e.g. a buyer’s plant idles for lack of parts) | Exporters often exclude them by contract |
| Mitigation | The injured party must take reasonable steps to limit its loss | A buyer of off-spec but saleable produce must try to resell, not let it rot |
| Termination / avoidance | Ends remaining obligations after a serious breach | Wrongful termination is itself a breach |
| Specific performance | Court orders the party to perform (pay, deliver, replace) | Common law: only when damages are inadequate; rarely sought in practice |
The CISG allows the full range — specific performance, substitute goods, price reduction, damages. Exporters commonly cap liability and exclude consequential damages, price reduction, or specific performance where enforceable.
c. Is suing worth it? A worked example
A Bolivian buyer suffers USD 50,000 of loss from a U.S. seller’s breach. Before suing, estimate the economics:
| Input | Estimate |
|---|---|
| Claim value | USD 50,000 |
| Own legal + forum costs to trial (foreign court) | USD 30,000 |
| Executive time, travel, translation | USD 8,000 |
| Probability of winning | 60% |
| If lost and loser pays applies: other side’s costs | USD 25,000 |
Expected value ≈ 0.60 × 50,000 − (30,000 + 8,000) − 0.40 × 25,000 = 30,000 − 38,000 − 10,000 = −USD 18,000
Even with a good case, suing abroad destroys value here. Every deal has a threshold below which litigation is irrational — and the forum and law clauses largely set where that threshold sits. (Collection risk on the judgment would push the number lower still.)
Below the threshold you need non-legal safeguards: export credit insurance, advance deposits, bank guarantees or performance bonds, and good credit information on the counterparty.
Also beware the mirror risk: being sued in a distant court. Ignore it and the claimant may win a default judgment that is later enforced against you — which is why parties resist forum clauses pointing to the other side’s home courts.
4.7 Negotiations and pre-contract liability
A contract is formed when a definite offer meets an unconditional acceptance. But contact starts much earlier — a catalogue, an inquiry, a request for tenders — and statements made along the way can matter.
- General rule: negotiating statements do not bind unless incorporated into the contract; courts let parties negotiate freely.
- Exception: if a contract results and a pre-contract statement was misleading, the party that made it can be liable. Apply common-sense good faith; avoid statements the other side is likely to rely on to its detriment.
a. Offers and tenders
An offer (tender) is addressed to a specific buyer, typically covering product, price, payment, and delivery, with the intention to be bound on acceptance. Whether a price quotation is an offer turns mainly on that intention. A tender is also a sales document: it should be professional, complete, and carry key selling points and specifications alongside general conditions, delivery time, and payment terms.
b. Acceptance
An acceptance must generally be unconditional. A conditional reply is usually a counter-offer, unless (under the CISG) the change is minor and the offeror does not promptly object. Make sure both sides have expressly agreed the same set of terms — easy to skip in fast email exchanges.
c. Letters of intent, MOUs, and other preliminary agreements
LOIs, MOUs, heads of agreement, commitment letters, and “agreements to agree” help when a major condition is still open (a bank loan approval, a government licence) or when parties settle basic points while negotiating the rest. The document itself may help unlock the approval.
The danger is a two-sided trap:
| Too vague / many disclaimers | Too detailed / no disclaimer |
|---|---|
| Bank or ministry will not rely on it | A court may hold it is already a binding contract |
Disclaimers like “not intended to create a binding contract” help but are not decisive everywhere. If terms are intentionally left open, the key question becomes whether there is a fallback mechanism a court could use to fill them. Rule of thumb: do not sign even a preliminary document you would not be prepared to perform if the other side accepted it.
4.8 Model and standard contracts
Many sectors run on standard forms — commodity markets almost require them.
| Source | Typical use |
|---|---|
| FIDIC (e.g. the “Red Book” for civil-engineering works) | International construction and engineering projects, often tendered in developing markets |
| Orgalime general conditions | Supply of mechanical and electrical products (European engineering industries) |
| UNECE general conditions | Supply and erection of plant and machinery (goods + services) |
| Legal form books and in-house precedent banks | Drafting starting points, tested in prior deals |
| ICC model contracts | Neutral templates for international sale, agency, distribution, franchising, intermediaries, turnkey projects, confidentiality, and more |
Worst use of a form: sign it unread. Best use: walk every clause before negotiating, mark each as favourable / neutral / unfavourable to you, and plan your asks.

Takeaways
- An export deal is a chain of contracts; the sale is the master — draft it fully and in writing
- Never sign terms you cannot read; oral side deals are hard to prove
- Always choose law + forum (or arbitration seat, language, arbitrators)
- The CISG applies by default between member states — exclude it expressly if you must
- Material changes in an acceptance = counter-offer; try to fire the last shot
- CISG does not cover trade terms or title — add Incoterms® and a title clause
- Price the lawsuit before filing it; below the threshold, rely on credit insurance, deposits, guarantees
- LOIs cut both ways — do not sign what you would not perform
