What is an NCNDA and why every international construction materials deal needs one

You introduce a buyer to a supplier. The first deal closes and you earn your commission. Three months later, the buyer contacts the supplier directly, cuts you out, and places a second order without telling you. This happens. It happens enough that the entire international trade intermediary industry runs on a standard document designed to prevent it.

That document is the NCNDA: Non-Circumvention, Non-Disclosure Agreement.

TL;DR

• An NCNDA protects the intermediary's commission by preventing buyers and suppliers from cutting them out after an introduction is made.
• It also protects buyers: a well-drafted NCNDA includes confidentiality provisions that prevent the supplier from sharing your project specs, pricing, or volumes with competitors.
• In international construction material deals, the NCNDA is typically signed before any supplier names, pricing, or factory contact information is shared.

What an NCNDA actually covers

A standard NCNDA in international trade has three operative sections.

Non-circumvention clause. The buyer agrees not to contact the supplier directly, and the supplier agrees not to contact the buyer directly, for a defined period: typically 2 to 5 years from the date of signing. Any direct transaction between buyer and supplier that was introduced through the intermediary obligates the party that circumvented to pay the intermediary's commission on that transaction, plus often a penalty.

Non-disclosure clause. Both parties agree to keep confidential all proprietary information shared during the business relationship: supplier identities, factory locations, pricing, deal terms, buyer project details, and any other commercially sensitive information. This is mutual: the buyer's project data and budget are protected from disclosure to third parties just as the intermediary's supplier list is.

Non-compete clause (sometimes included, sometimes separate). Restricts parties from entering the same category of business in competition with the intermediary during the agreement term. This clause is less universal than the first two and is often negotiated out or limited in scope.

When to sign it

The NCNDA is signed before any protected information is shared: not after. This is the most common mistake buyers make.

In practice, the sequence in a well-run international sourcing deal looks like this:

What happens without one

Without an NCNDA, circumvention is still a breach of contract if a commission agreement is in place, but it is much harder to enforce. You would need to demonstrate damages, prove the relationship existed, and often pursue the claim in a foreign jurisdiction if the buyer or supplier is overseas.

The NCNDA creates a documented, pre-agreed framework for the relationship. When circumvention happens: and it does happen: the injured party has a clear contractual basis for a claim, an agreed penalty clause, and documented evidence that all parties understood the terms.

For the buyer, signing an NCNDA is also protection. A buyer who has signed an NCNDA with a legitimate intermediary has documentation that their project details, specifications, and pricing were handled confidentially. Without it, a supplier who received your project specs could share them with your competitors or with other buyers looking for similar material.

Key terms to check in any NCNDA

Not all NCNDAs are equal. Before signing one: or before using a template: verify these provisions are clearly defined:

NCNDA and IMFPA: the two documents in international trade

You may encounter a second document alongside the NCNDA: the IMFPA, or Irrevocable Master Fee Protection Agreement. Where the NCNDA protects against circumvention and unauthorized disclosure, the IMFPA specifically documents the commission structure and the chain of intermediaries involved in a deal.

In multi-intermediary deals, where multiple brokers or agents are involved between a buyer and a manufacturer: the IMFPA establishes who gets paid what, in what order, and with what documentation. It is common in commodity and large-scale material transactions.

For most construction material sourcing deals involving a single intermediary and one buyer-seller relationship, the NCNDA alone is sufficient. The IMFPA becomes relevant when the commission chain has more than two parties.

How Nexo uses the NCNDA

At Nexo, every deal begins with an NCNDA signed by the buyer and our company before any supplier information is shared. This is standard practice, not a formality: it protects both parties and creates the foundation for a transparent, long-term sourcing relationship.

Buyers who sign our NCNDA can expect: confidential handling of their project specs, pricing, and volumes; a documented commission structure agreed in advance; and a clear framework for the relationship that governs any follow-on orders with suppliers introduced through Nexo. While the legal piece is being signed, you can already run our landed cost calculator on the spec to know your target number, and compare with your current domestic quote to see what the direct path actually saves you.

Start a sourcing conversation with Nexo. The NCNDA is a one-page document that we send as the first step: sign it, and we share the supplier shortlist the same day.
