Free Trade Agreements (FTAs) continue to unlock global opportunities for New Zealand exporters. At the Natural Health Products NZ Summit 2025, TradeWindow’s Peter Webb took the stage to share practical insights into how exporters can make the most of these agreements through accurate and strategic use of Certificates of Origin (COOs).

If you’re exporting, or thinking about it, here’s a concise breakdown of what you need to know to harness the full power of FTAs in your business.

Why Free Trade Agreements Matter

Free Trade Agreements help businesses access lower or zero tariffs and can even facilitate quicker customs clearance in key markets. With agreements worldwide and new ones like the NZ-India FTA on the horizon, it’s vital to stay aware of your FTA entitlements to remain competitive internationally.

Exporters in Australia, for example, have been leveraging their FTA with India since 2022. New Zealand exporters will want to be ready to follow suit as negotiations progress.

Certificates of Origin: Your Ticket to Preferential Treatment

When your product qualifies under a Free Trade Agreement, a Certificate of Origin can unlock significant cost savings through lower or zero tariffs. For example, under the NZ–UKFTA, the tariff on a probiotic supplement dropped from 12% to 0%, equating to a landed cost saving of $16,200 on a 2,500-unit shipment. That’s not small change.

Better yet, some FTAs like the NZ–China CFTA, grant you preferential customs treatment. Your goods could jump the queue, which is especially important for time-sensitive or perishable products.

Do You Always Need a Certificate of Origin?

Not always, but often.

Most FTAs require a certificate to be issued by an authorised issuing body (like TradeWindow Origin or The Chamber of Commerce). However, the CPTPP (Comprehensive and Progressive Trans-Pacific Partnership) allows for self-certification by the exporter, importer or producer.

But here’s the catch: even if you can self-certify, understanding the rules or origin is still critical. If your product contains imported ingredients, determining origin eligibility can get complicated fast.

Determining Origin: Wholly NZ Produced vs. Product-Specific Rules (PSRs)

Let’s break down the two common pathways to proving origin:

Wholly NZ Produced Goods

If your product is entirely made from New Zealand or partner-country ingredients, things are relatively straightforward. You’ll need:

• The correct HS (Harmonised System) code
• Shipping details
• Destination address

Example: Milk protein concentrate exported to the UK under the NZ–UKFTA meets these criteria easily.

Product-Specific Rules (PSRs)

If your product includes imported ingredients, it may still qualify, but only if those ingredients have been sufficiently transformed. The general rule? The final product’s HS code must differ (often at the chapter or heading level) from that of the imported ingredients.

Example: A product made from components imported under HS code 382100 was exported under HS code 210690. The transformation was enough to meet origin requirements under the NZ–UKFTA.

Repackaging alone usually won’t cut it.

No FTA? You Might Still Need a Certificate

For markets like the Middle East where no FTA exists, you may still need a Certificate of Origin, especially if your buyer demands one for letter of credit purposes. These are generally less complex and can be tailored to what the importer needs. Note: many Middle Eastern markets still require a wet signature from an authorised issuing body.

A Smarter Way to Certify: TradeWindow’s Streamlined System

TradeWindow is authorised to issue Certificates of Origin for both New Zealand and Australian exporters. The platform includes a unique pre-approval system that validates goods in advance. Once your goods are approved, they remain valid in the system for two years, so issuing your certificates of origin becomes super-fast and the service is available for submittions 24/7, 365 days a year.

It’s a practical solution that keeps manual processing from slowing your exports.

Planning a New Product or Market Entry? Get Advice Early

Peter Webb closed his session with a reminder: HS code classification can be tricky. The same product can fit multiple categories, and different countries can interpret codes differently. The right classification can be the difference between qualifying for zero tariffs or missing out entirely.

If you’re launching a new product or entering a new market, don’t guess. Reach out for support and get it right from the start.
