CISG (International Sale Of Goods): Essential Australian Guide

Trading across borders opens doors for Australian businesses - new customers, bigger orders and stronger supply chains.

But international sales also mean different legal systems, languages and customs. That’s where the CISG (United Nations Convention on Contracts for the International Sale of Goods) helps, by providing a neutral, globally recognised set of contract rules for cross‑border sales of goods.

In this guide, we’ll explain what the CISG is, when it applies in Australia, how it affects your contracts, and how to opt out if you prefer to rely on a chosen domestic law. We’ll also share practical drafting tips and the core legal documents to have in place so you can trade overseas with confidence.

What Is The CISG And When Does It Apply In Australia?

The CISG is an international treaty that standardises core rules for contracts to sell goods between businesses in different countries. Australia is a party to the CISG, so it sits alongside Australian contract law when you sell goods internationally.

It generally applies when:

• There’s a contract for the sale of goods (not services); and
• The seller and buyer have their places of business in different countries that are both CISG member states; or
• Private international law rules point to the law of a CISG country.

The CISG does not cover every scenario. It generally excludes consumer purchases for personal use, auctions, sales by authority of law, stocks and shares, negotiable instruments, ships/aircraft/hovercraft and electricity. Importantly, it does not deal with the validity of a contract (for example, whether a clause is unfair under local law) or when title/ownership passes - those questions are determined by the governing law you choose (or that a court selects under conflict rules).

Two other important exclusions and limits to remember:

• Article 5: The CISG does not apply to liability for death or personal injury caused by the goods. Those issues are handled by other laws in the relevant jurisdiction.
• Article 39(2): There is an absolute two‑year cutoff for notifying a seller of non‑conformity, running from the date the goods were actually handed over (unless a longer period is agreed). Even if a buyer gives “reasonable time” notice, waiting beyond two years can bar claims for non‑conformity.

Good to know: You and your overseas counterparty can agree to exclude the CISG altogether (Article 6) and apply a nominated law instead. We cover how - and when - that can make sense below.

Key CISG Rules You Should Know (Formation, Delivery, Risk And Remedies)

Contract Formation: Offers, Acceptances And The “Battle Of The Forms”

The CISG contains its own formation rules: you still need an offer and acceptance, but the details can play out differently to what you may expect under Australian law. For example, under the CISG, an acceptance that adds or changes terms is treated as a counter‑offer if it materially alters the offer. This really matters when both sides exchange standard terms (the classic “battle of the forms”).

To reduce uncertainty, control your order process and make it clear which terms prevail. It can also help to revisit the basics of offer and acceptance and how an invitation to treat differs from a binding offer.

Delivery, Conformity, Inspection And Risk Transfer

Sellers must deliver goods that conform to the contract (including quality, quantity and packaging) and hand over required documents (such as bills of lading). Buyers must take delivery and pay the price.

Risk transfer under the CISG generally follows who is responsible for handing the goods to a carrier:

• If the contract involves carriage and the seller is not bound to deliver at a particular place, risk usually passes when the seller hands the goods to the first carrier (Article 67).
• If the seller must deliver the goods at a particular place, risk passes when the goods are handed over at that place.
• Where there is no carriage (for example, buyer collection), risk passes when the buyer takes over the goods (Article 69).

These default rules can surprise teams used to domestic practice. To avoid misunderstandings, most international contracts also adopt Incoterms (for example, FOB, CIF, DDP). Spell out the chosen Incoterm, the named place/port, and who handles export/import formalities, insurance and transport.

Inspection and notice are critical under the CISG. Buyers must examine goods within a reasonable time and notify the seller of any lack of conformity within a reasonable time after they discover (or ought to have discovered) it (Article 39(1)). On top of that, Article 39(2) imposes a hard stop - a buyer cannot rely on a lack of conformity if they don’t give notice at the latest within two years from the date the goods were actually handed over, unless this period is inconsistent with a contractual guarantee. Because late or vague notices can limit remedies, set clear inspection procedures, testing standards and notice methods in your contract.

Price, Payment And Interest

Unless you specify otherwise, the CISG implies the buyer must pay the price at the time and place stated in the contract. If not stated, default rules apply - typically payment when the goods or shipping documents are made available. The CISG allows recovery of interest on late payments, but it does not specify the rate. This is one reason to include a clear interest clause and specify currency, due dates and any set‑off rights.

Remedies, Damages And “Fundamental Breach”

Both buyers and sellers have meaningful remedies under the CISG, including:

• Requiring performance (for example, delivery of missing items or replacement of non‑conforming goods);
• Avoiding (terminating) the contract for fundamental breach; and
• Damages for loss caused by the breach (including loss of profit), limited by foreseeability and subject to a duty to mitigate.

“Fundamental breach” (Article 25) means a failure that substantially deprives the other party of what they were entitled to expect under the contract. To bring clarity, define what will amount to a fundamental breach for your product and build in cure periods and notice steps.

Even with the CISG’s damages framework, it’s still wise to use familiar risk controls in your contract - caps on liability, exclusions for indirect loss, agreed limitations periods and force majeure procedures. Well‑drafted limitation of liability clauses can sit alongside the CISG and provide certainty for both sides.

Three Common Day‑To‑Day Scenarios

1) “We’ve always shipped FOB - do we need to change anything?”
Probably not, but make it explicit: “FOB Sydney Incoterms 2020” and the named port. Under the CISG, risk can pass when goods are handed to the first carrier, which is often earlier than teams expect. Clarify risk transfer, inspection, acceptance and what happens if goods are damaged in transit.

2) “The buyer sent their standard terms after we issued ours.”
That’s the battle of the forms. Under the CISG, a response that materially changes the offer counts as a counter‑offer. Reduce ambiguity by controlling the order process (for example, your quote plus the buyer’s purchase order equals acceptance to your terms) and include a clear precedence clause.

3) “The goods are late - can the buyer terminate?”
It depends on whether the delay is a fundamental breach. Time‑critical orders (for example, seasonal stock) might cross that threshold. Set realistic lead times and a cure process in your contract so both parties have a roadmap for managing delays.

CISG, Australian Law And Your Contract Toolkit

The CISG will often be part of the legal picture for international sales, but it won’t be the whole picture. In Australia, other regimes may also apply - and some cannot be contracted out of.

Australian Consumer Law (ACL)

If you sell to Australian customers, elements of the Australian Consumer Law (ACL) can apply alongside the CISG, especially around misleading conduct and product claims. Be careful with product descriptions, marketing claims and promises - the ACL prohibits misleading or deceptive conduct under section 18. If your marketing includes specific statements about quality, origin or performance, make sure you can substantiate them to avoid false representation issues.

If you offer repair or replacement promises, align any warranty wording with your CISG remedies and the ACL’s expectations (for example, making sure your warranty text includes mandatory notices where required). Keep your terms consistent across markets to avoid confusion.

Validity, Title And Property Issues

The CISG doesn’t govern whether a clause is “valid” (for example, whether it’s unfair or unenforceable) or when title passes. Those issues are governed by the chosen local law (or the law selected by conflict rules). This is why your governing law and dispute resolution clauses are critical and should be drafted with cross‑border enforcement in mind.

Liability Allocation, Insurance And Force Majeure

The CISG’s damages and mitigation rules don’t replace sensible risk allocation. Use liability caps, exclusions of indirect or consequential loss where appropriate, agreed limitation periods, and a practical force majeure process (notice, mitigation steps and termination triggers). Align these with your insurance policies so you’re not promising remedies you can’t realistically support.

Security, Retention Of Title And Payment Protection

If you sell on credit, think about retention of title (ROT) and security interests to protect against non‑payment. For Australian buyers, registering your security on the Personal Property Securities Register is often essential - it’s a powerful tool for suppliers that sell domestically or import stock for on‑sale, and a big reason the PPSR matters to your business.

Confidentiality, IP And Pre‑Contract Discussions

Before you start swapping drawings, pricing and manufacturing methods with new overseas partners, consider using an International NDA to protect confidential information. Your sales contract should also address tooling ownership, trade mark use, reverse engineering and IP infringement processes in the destination market.

Should You Exclude The CISG? How To Make The Call

You can opt out of the CISG (Article 6). Many Australian exporters and importers do, while others keep it. The right answer depends on your product, counterparties and bargaining position.

When Businesses Often Exclude The CISG

• You want a familiar domestic law (for example, New South Wales law) to apply end‑to‑end.
• Your industry uses risk allocations and concepts that your local law addresses more directly than the CISG.
• Your team and advisers prefer one legal framework to reduce uncertainty and cost.

When Keeping The CISG Can Help

• You’re selling into multiple jurisdictions and want a neutral, internationally recognised baseline that many overseas buyers already understand.
• You want to minimise negotiation friction over which national law applies.
• Your products and logistics align well with the CISG’s default rules, especially when combined with precise Incoterms.

How To Document Your Choice

Whichever path you choose, make it explicit. A typical approach is to include:

• A governing law clause (for example, “The laws of New South Wales, Australia apply”).
• An express statement either excluding or confirming the CISG (for example, “The United Nations Convention on Contracts for the International Sale of Goods (CISG) does not apply to this agreement.”).
• A jurisdiction or arbitration clause suitable for cross‑border enforcement.
• Clear Incoterms, delivery, inspection and risk transfer provisions aligned with your logistics.

Commercially, plan for cash flow too. Spell out deposits, letters of credit if relevant, late payment interest and any security or guarantees. Many suppliers standardise these points in their Terms of Trade so they are consistent across customers and markets.

What Legal Documents Will You Need?

Most international sales relationships run smoothly when your paperwork is clear, consistent and designed for cross‑border reality. Depending on your model, consider the following documents.

• Terms of Trade / Sale of Goods Agreement: Your core commercial terms covering pricing, delivery, Incoterms, risk transfer, acceptance testing, warranties, remedies and liability. If you operate on standard terms, a robust set of Terms of Trade is essential.
• International NDA: Protects confidential information and product IP during early discussions, sampling and quoting. An International NDA helps keep pre‑contract conversations safe across borders.
• Distribution or Reseller Agreement: If a local partner will market and sell in their territory, set the territory, performance targets, branding rules, pricing parameters and termination rights.
• Manufacturing Agreement: If you outsource production, govern specifications, quality control, tooling ownership, lead times, pricing, audits and non‑conformity management (including inspection windows and Article 39 notice timelines).
• Credit Application & Security Terms: For open‑account sales, include credit limits, late fees, guarantees and retention of title/security rights. For Australian buyers, consider PPSR registration to secure your position.
• Website Terms & Policies: If you take international orders online, align your website terms, returns and privacy practices with your contract and compliance obligations.
• Warranty & After‑Sales Procedures: Provide clear warranty terms, parts/repair logistics and contact points so issues can be resolved quickly across time zones - and align with both the CISG and your ACL settings (such as the rules linked to misleading conduct).

When tailoring or updating your templates for global use, double‑check that your liability, warranty and delivery clauses reflect your real‑world operations and insurance. It’s also worth aligning your liability settings with your chosen governing law and the CISG’s remedies framework so there are no gaps.

Practical Checklist For Cross‑Border Sales

• Confirm CISG Applicability: Are both parties in CISG countries, or will your chosen law make the CISG apply? Decide whether to adopt or exclude it and say so in writing.
• Lock In The Right Incoterm: Select the Incoterm and named place that match your logistics and margins. Clarify insurance and customs responsibilities.
• Set Payment Mechanics: Specify currency, method, due dates, interest and set‑off. Consider deposits, escrow or LCs to de‑risk credit exposure.
• Define Specs, Quality And Acceptance: Attach detailed specifications and testing standards. Include inspection windows and notify‑by dates so Article 39 timelines are crystal clear.
• Allocate Liability Thoughtfully: Use caps, exclusions of indirect loss and realistic remedies, supported by your limitation of liability position and insurance.
• Protect IP And Confidential Info: Use an International NDA during negotiations and ensure the sales terms prohibit reverse engineering and misuse of trade marks.
• Secure Payment Where Needed: Consider retention of title and PPSR registration for Australian buyers - a key reason PPSR matters.
• Choose Enforceable Dispute Options: Pick a court jurisdiction or arbitration seat suited to cross‑border enforcement and include practical procedures (language, timelines, service).
• Stay Compliant: Check sanctions/export controls, product compliance and labelling rules in the destination market, and keep your ACL obligations in view for Australian sales and marketing.

Key Takeaways

• The CISG provides a neutral, international framework for cross‑border sales of goods and often applies by default to Australian exporters and importers.
• Remember two key limits: the Article 39(2) two‑year cutoff for notices of non‑conformity and the Article 5 exclusion for death or personal injury claims.
• Core CISG areas to manage in your terms include formation (and the battle of the forms), delivery/inspection, risk transfer, damages and what counts as a fundamental breach.
• Australian regimes like the ACL can still apply to your marketing and warranties, and security interests like PPSR are critical for credit sales.
• Whether to exclude the CISG depends on your product, markets and bargaining position - make your choice explicit, and align governing law, dispute resolution and Incoterms.
• Strong contracts such as Terms of Trade, an International NDA and clear liability settings help manage risk and keep cash flow predictable.
• For formation and offer mechanics, it helps to refresh the basics of offer and acceptance and what counts as an invitation to treat when you’re trading internationally.
