What the CISG Is and When It Applies Automatically

The United Nations Convention on Contracts for the International Sale of Goods is a treaty.

Two questions matter most. First, are the parties’ businesses in different countries that have joined the treaty? Second, is the deal a sale of goods?

Place of Business, Not Nationality, Is the Key Test

A Brandon manufacturer with its operations in Florida, selling to a customer whose main office is in another member country, fits the usual pattern. The owner’s citizenship does not change that.

A company with several locations raises a harder question. Review that point before you sign, not after a shipment goes wrong.

What Falls Outside the Convention: Goods, Services, and Mixed Deals

Many deals mix goods and services. A seller might sell equipment and also install it. Courts look at which part of the deal matters more. Florida’s Article 2 rules work the same way. Under Fla. Stat. § 672.102, when the sale-of-goods aspects of a hybrid transaction predominate, the chapter applies to the transaction, though other law may also apply to aspects that do not relate to the sale of goods. It applies only to the goods provisions when they do not. The chapter also does not impair statutes regulating sales to consumers, farmers, or other specified classes of buyers.

That is why a Florida deal can raise both treaty and state-law questions.

How a Choice-of-Law Clause Changes the Answer

A governing-law clause names the law that will interpret the contract. It matters, but it rarely settles the question alone. Under Fla. Stat. § 671.105, when a transaction has a reasonable relation to Florida and to another state or nation, the parties may agree which law governs.

For larger deals, Fla. Stat. § 685.101 goes further. Under Fla. Stat. § 685.101, parties to a contract involving in the aggregate not less than $250,000, or services or tangible or intangible property of equivalent value, may, to the extent permitted under the United States Constitution, agree that Florida law will govern the contract, whether or not it bears any relation to Florida. This applies to the extent the United States Constitution permits, even without a Florida tie. Some contracts are excluded, including labor or employment contracts. Personal, family, or household deals are also excluded, unless the contract concerns a trust with at least one trustee who resides or transacts business as a trustee in Florida, in which case the section applies (Fla. Stat. § 685.101).

So a clause picking Florida law does not, by itself, decide whether CISG applies to sales contract terms. The exact wording matters. A general reference to a state’s commercial code does not answer the question either. Read the clause word by word with the rest of the paperwork.

How Parties Can Exclude the CISG by Agreement

The usual method is a clear exclusion sentence placed in the governing-law clause. The sentence should name the treaty by its full title and state that it does not apply.

Consistency matters as much as the wording. Purchase orders, invoices, and standard terms often conflict. If one document says the treaty applies and another says nothing, a dispute can turn on which document controls.

Incoterms set delivery and risk terms. Arbitration clauses need the same care. The ICC guidance on arbitration clauses advises naming the governing law, the place of arbitration, and the language, and avoiding ambiguous wording.

Deadlines and Limitations Periods Still Matter

Florida’s statute of limitations sets how long a party has to file suit. Under Fla. Stat. § 95.11, the period depends on the type of claim. For example, Florida law sets its own time limit for an action founded on fraud.

Under Fla. Stat. § 95.03, a contract provision fixing a shorter time to sue, compared with the applicable statute, is void.

Some contracts also require prompt notice of defects or late delivery. Missing a notice step can hurt a claim. Deadlines can start running before a problem looks serious, so identify the governing law early.

Where a CISG Dispute Is Heard and Serving a Foreign Party

A dispute can go to a Florida court or to arbitration, depending on the forum clause. For court cases, Fla. Stat. § 47.011 limits where actions may be brought. The county is where the defendant resides, where the cause of action accrued, or where the property in litigation is located. That section does not apply to actions against nonresidents.

Under Fla. Stat. § 682.02, a court decides whether an arbitration agreement exists. An arbitrator decides certain conditions before arbitration. The ICC arbitration overview explains that parties can consent to ICC arbitration through a contract, including after a dispute arises.

Next Step: Review Your Contract’s Governing Law Terms

Unclear governing-law language is easier to fix before a dispute starts. If you have a sales contract with a buyer or seller abroad, and its governing-law or exclusion terms are unclear or already disputed, Ayala Law PA can review the contract with you. The firm focuses on business litigation, including international trade litigation. The answer depends on the contract’s wording and where each party does business, and no result can be predicted in advance. To arrange a case evaluation, call (305) 570-2208 or use the contact page.

Does CISG apply to sales contract deals with every foreign buyer?

No. Whether CISG applies to sales contract terms depends on the parties’ locations, the goods, and the contract’s wording.

Can a Florida contract exclude the CISG?

It can, through a clear exclusion sentence. The wording must be consistent across all the deal documents.

Does the CISG cover services?

It covers sales of goods, not pure services. Mixed deals need review of which part of the contract matters more.

What to review in your cross-border sales contract

Parties and locations

Confirm where your buyer and seller are located before relying on any default rule.

Governing law and forum

Choice of law and venue clauses determine where and how a dispute is resolved, so they should be reviewed alongside the CISG question.

Keep your deal documents consistent

Quotes, purchase orders, invoices and standard terms often conflict. An exclusion or choice-of-law clause in one document may not match the others. Review the full set of paperwork before a dispute arises.

Common cross-border sales disputes we review

Nonconforming goods

Disagreements over whether delivered products match the description, quality or quantity in the contract.

Payment and delivery terms

Disputes over when payment is due, what delivery terms mean, and who bears the cost of late or incomplete shipments.

Governing law and forum

Questions about which country's law applies and whether a dispute belongs in a Florida court or in arbitration.

Contract formation

Conflicts over whether a binding agreement was formed through emails, purchase orders, quotes or conflicting standard terms.
