Excluding the Vienna Sales Convention (CISG) through general terms and conditions requires careful attention to language requirements and proper incorporation. Many international businesses assume their standard exclusion clause automatically applies, but Dutch courts and the CISG itself impose specific conditions that determine whether such exclusions are valid.
The CISG governs international sales contracts between businesses located in different contracting states. Article 6 of the Convention permits parties to exclude its application entirely or derogate from specific provisions. This flexibility makes the CISG popular for international trade, yet the exclusion mechanism creates practical challenges that catch many foreign companies off guard.
Why Does the Language of Your General Terms Matter under Dutch Law?
Under the CISG, a reference to general terms and conditions must be made in a language the other party could reasonably be expected to understand. A Dutch company that references its terms only in Dutch while conducting negotiations in English risks having those terms declared inapplicable.
The CISG Advisory Council Opinion No. 13 addresses this issue directly in rule 6.2. The reference to general terms must appear in the language of negotiations, the language of the contract, or a language the receiving party ordinarily uses. Dutch courts, including the District Court of Overijssel and the District Court of Gelderland, have followed this guidance in their rulings.
Consider this scenario: a Dutch buyer sends an order confirmation in English to a Spanish seller. The Dutch company's letterhead contains a reference to its purchase conditions, but this reference appears only in Dutch. The Spanish seller ships the goods without objection. When a dispute arises, the Dutch buyer claims its general terms apply. Under the CISG, this claim will likely fail because the reference was not in a language the Spanish seller could reasonably understand.
This outcome differs from purely domestic Dutch law. The Dutch Supreme Court has not required that references to general terms in international cases must be in the language of negotiations or a language the other party understands. This distinction matters when determining which legal framework governs your contract.
How Does the Battle of Forms Work in International Sales?
When both parties refer to their own general terms during contract formation, a "battle of forms" arises. The CISG resolves this through the knock-out rule, which eliminates conflicting provisions while preserving terms that match.
Dutch domestic law applies the "first shot rule" instead. Under this approach, the first party to reference its general terms prevails unless the second party explicitly rejects those terms. The second reference has no effect without express rejection of the first terms.
The CISG Advisory Council recommends a different approach in Opinion No. 10. Under the knock-out rule:
- Terms that are materially identical in both sets of conditions remain part of the contract
- Conflicting terms are eliminated from the agreement
- Gaps left by eliminated terms are filled first by the CISG itself, then by applicable national law
A recent case involving a Dutch seller and German buyer illustrates these principles. Both parties referenced their general terms during contract formation for the purchase of tubes used in heat exchangers. The tubes proved defective, causing substantial losses including expert investigation costs, replacement expenses, and penalties from the end customer.
Both sets of general terms contained provisions limiting liability for damages. These provisions conflicted with each other and were therefore knocked out. However, both parties had included clauses excluding the CISG. Because these clauses matched, the exclusion remained valid. The dispute over damages then fell to be determined under Dutch law pursuant to article 4(1)(a) of the Rome I Regulation, which designates the seller's country of habitual residence as the governing law for sales of movable goods.
What Are the Requirements for Valid Incorporation of General Terms?
Articles 14 and 18 of the CISG, read together with articles 8 and 9, establish that general terms become part of a contract when both parties expressly or impliedly agree to incorporate them and when the other party had a reasonable opportunity to review the terms.
The first requirement focuses on consent. A mere reference to general terms on an invoice sent after contract formation typically fails to incorporate those terms. The reference must occur during contract formation, and the other party must have an opportunity to accept or reject the terms before the contract concludes.
The second requirement concerns accessibility. The party seeking to rely on general terms must ensure the other party could actually review them. Providing terms upon request is generally insufficient. Best practice involves:
- Attaching the full text of general terms to the offer or acceptance
- Providing a clearly accessible hyperlink in electronic communications
- Ensuring the terms are available in an appropriate language
Dutch courts examine whether the receiving party had a genuine opportunity to familiarize themselves with the terms before agreeing to the contract. A reference buried in fine print or provided only after agreement may not satisfy this requirement.
When Should You Seek Professional Advice on CISG Exclusions?
The interaction between the CISG, national law, and the Rome I Regulation creates complexity that requires careful analysis for each transaction. Mistakes in exclusion language or incorporation procedures can leave businesses without the protections they assumed they had.
Foreign companies entering the Dutch market or contracting with Dutch businesses face particular challenges. The differences between Dutch domestic rules and CISG requirements mean that assumptions based on home jurisdiction practices may prove incorrect. A liability limitation that would be valid under your domestic law might be knocked out under CISG principles or declared inapplicable due to language deficiencies.
Reviewing your general terms for international transactions involves examining the exclusion clause itself, the language of references, the method of incorporation, and the substantive provisions that would apply if conflicting terms are eliminated. For matters involving international sales contracts and CISG exclusions, professional legal advice helps avoid costly disputes.
