If you buy aluminium profiles, extrusions, channels or sections from China, pay attention to what’s happening in Wellington right now. New Zealand’s aluminium extruders have asked the Government to put a safeguard duty on imported extrusions, and the Government’s own investigation report has just landed on the Minister’s desk.
No decision has been made yet. But if a duty does come in, the cost of importing aluminium profiles could go up. Here’s what’s going on, who it affects, and why planning your next order now could save you money.
What’s happening
Local extruders say cheap imports, mainly from China, are making it very hard for them to compete. Here’s the timeline so far:
- 21 January 2026: the Aluminium Extruders Association of New Zealand (ALENZ) applied to MBIE for a safeguard investigation into imported extruded aluminium products.
- 28 May 2026: the investigation officially started, and New Zealand notified the World Trade Organization.
- Early September 2026: Commerce and Consumer Affairs Minister Cameron Brewer decided not to put an emergency (provisional) duty in place while the investigation was still running.
- 24 September 2026: MBIE delivered its findings to the Minister, and the industry is now pushing him to act quickly.
Both sides of the argument
The local industry says imports of finished aluminium products are running around 40% higher than last year, and that these imports are state-subsidised, mainly by China. They argue that other countries already protect their aluminium industries while New Zealand’s market is wide open.
The exporters say the opposite. China’s Non-Ferrous Metals Industry Association, along with Indonesian and Mexican interests, point to Stats NZ data showing import volumes for the relevant tariff codes actually fell between 2022 and 2025. ALENZ disputes that.
It’s now the Minister’s call.
What a safeguard duty would mean for importers
- It isn’t limited to China. A safeguard responds to a jump in imports from anywhere, so switching to a factory in another country may not get you around it.
- It can last years. A full safeguard measure can run for up to four years unless it’s reviewed and extended.
- The products in scope are certain aluminium extrusions under tariff codes 7604.21.00 and 7604.29.09: aluminium alloy profiles, bars and rods.
Who should pay attention
If your business buys aluminium sections to make or sell something, this could hit your costs. That includes:
- Joinery, window, door and balustrade makers
- Fencing, gate and pergola businesses
- Shopfitters, shelving and display makers
- LED lighting businesses using aluminium channels
- Builders, renovators and trade suppliers buying in volume
Not every aluminium product falls under these two codes. The exact classification of your product matters, so check it before you assume you’re in or out.
Why ordering early could save you money
Trade duties normally apply from the date they take effect, based on when goods are cleared through customs. Stock that lands and clears before then is usually charged at today’s rates. That’s why importers watching this case are planning ahead:
- Lock in today’s landed cost. Get your next few months of stock in at current pricing before any new duty is added.
- Beat the rush. If a duty is announced, many importers will try to order at the same time. Factories get busy and lead times stretch.
- Protect your quotes. If you’ve already quoted customers on jobs, stock bought now keeps your margins safe.
- Plan with real numbers. Work out your landed cost with and without a possible duty, so you’re ready either way.
A word of balance: no duty has been confirmed, and nobody knows yet what rate it would be. Don’t overstock on a guess. Order what you can realistically sell or use, and keep cash flow in mind. Always confirm timing and classification with a licensed customs broker.
How I can help
I import by the container for my own businesses and deal with factories, freight and customs every week. For aluminium profiles, I can help you:
- Find the right factory and compare quotes, including face to face at the Canton Fair in Guangzhou this October.
- Check your tariff code so you know whether your product is likely to be in scope.
- Work out your landed cost today, and what it would look like if a duty is added. More on that here: What is landed cost, and why it matters before you order.
- Arrange shipping and customs, LCL or full container, so your goods arrive and clear on time.
The sooner you plan, the more options you have.
