Every shipment you send across borders without claiming trade preferences is money leaking from your margin. For Kiwi businesses managing cross-border sales, that leak almost always comes down to paperwork nobody had time to chase.
We can help you stay on top of these treaty rules before a shipment ever leaves the country. Here's how to identify eligible tariff cuts, organise your paperwork, and protect your business from back-tax bills.
Preferential tariffs give your products a real price advantage in foreign markets. They lower or remove customs duties, which makes your landed cost more attractive to overseas buyers.
Here's what that advantage looks like in practice:
Duty Cuts: Treaties often drop import tax rates to 0% over a set timeline.
Competitive Pricing: Lower tax barriers let you match or beat local prices in your export markets.
Supply Resilience: Sourcing parts from treaty-aligned countries helps you build a more stable supply chain.
According to the 2025 Thomson Reuters Institute Corporate Tariffs Survey, only 33% of businesses use technology to automate their FTA compliance. This means most are still managing it by hand and likely leaving savings on the table.
Failing to claim these discounts can wipe out your profit margins on high-volume shipments. MyGTS helps you find the correct export and import tariff codes for your goods. Once you've entered those codes, the Pre-Shipment Plans tab shows you the customs and trade documents you'll need, including any FTA privileges that apply.
If you're shipping from a hub like South Auckland, understanding these rules matters even more. For large-scale projects, key agreements like the New Zealand-China Free Trade Agreement can help keep your export costs down.
Claiming lower tariff rates requires a correct Certificate of Origin that can withstand a border audit. Customs offices enforce strict rules to verify your goods qualify under the trade deal, and a single mistake on the form can get your preference claim rejected.
Our Multiline Entry and Export Declaration services help you get this paperwork ready. We can help assemble your documents according to trade rules, but the final compliance remains your responsibility.
Structure your records around these four checks:
Prepare your files early to avoid bottlenecks. Logistics capacity often changes quickly during the January summer shutdown, which makes early preparation even more important.
Customs agencies can audit your trade records several years after a shipment clears the border, and if they find your origin claims were incorrect, they can issue back-tax bills and serious penalties. A clear compliance trail is what protects you when that audit happens.
Automated screening tools in MyDHL+ help you find and fix missing data before you submit files to customs. This helps catch the kind of gap that can turn into a problem years later.
Review your current trade risk against these common gaps:
Compliance Risk | Operational Impact | How to Protect Your Business |
Expired Documents | Leads to immediate rejection at the border | Set automatic alerts for treaty certificate expiry dates |
Incorrect Formulas | Causes errors in your regional value calculations | Standardise your bills of materials with updated costs |
Poor Document Storage | Leaves you unable to produce proof during an audit | Keep digital records of all manufacturing logs and customs paperwork for at least seven years |
Wrong HS Codes | Triggers tariff reassessments and steep misclassification fines | Review products regularly against customs updates |
Failing to track these details can lead to unexpected debt. A small error of around NZ$90 per invoice adds up fast when applied retroactively over a whole year of shipments.
Reducing your export costs comes down to correct paperwork and proactive tracking, done consistently. We support that with MyGTS for tariff code lookups and Pre-Shipment Plans, plus Multiline Entry and Export Declaration services to keep your paperwork moving.

They lower or remove the import duties on your goods when they enter a destination country, sometimes down to zero. That tax relief makes your products more price-competitive against firms shipping from countries that don't have a similar agreement in place.
It's official proof that your goods were manufactured or processed within a treaty territory. Customs authorities require this document to verify your shipment meets the strict rules of the trade deal, which lets you claim the lower duty rate.
Yes, customs authorities can audit your trade records up to several years after your goods clear the border. If they find errors in your paperwork, they can charge substantial back-taxes, interest, and regulatory fines.
MyGTS helps you find the correct export and import tariff codes for your goods. Once you've entered those codes into the Pre-Shipment Plans tab, you can see the customs and trade documents you'll need, including any FTA privileges that apply to your shipment.
We offer services like Multiline Entry, Export Declaration, and permit processing to help you generate paperwork that meets international standards. However, your business still holds the final responsibility for ensuring full compliance.
