If you’ve ever worked in manufacturing—whether it’s building electric motors, transformers, renewable energy generators, or even the small components in household appliances—you’ve likely relied on Non Oriented Silicon Steel (NOS steel), a specialized alloy with excellent magnetic properties that’s core to so many electromechanical systems. As someone who’s supplied NOS steel for over a decade, I’ve seen first-hand how trade policies can turn a smooth supply chain into a tangled web of regulations, tariffs, and unexpected barriers. For anyone in this space, whether you’re a manufacturer sourcing materials or a supplier navigating global rules, understanding the trade policies tied to NOS steel isn’t just a compliance box to check—it’s the difference between meeting a customer’s deadline and missing a critical production window. Let’s break down the key trade policies shaping this industry, and what they mean for everyone involved. Non Oriented Silicon Steel
First, it’s important to ground this in what makes NOS steel unique from other steel products. Unlike oriented silicon steel, which is engineered for specific grain alignment to maximize efficiency in high-frequency transformers, NOS steel’s random grain structure makes it ideal for motors where magnetic fields shift in multiple directions. This specificity means it’s not treated as generic steel in most trade agreements—regulators around the world classify it as a “specialty electrical steel,” which subjects it to its own set of rules, separate from flat-rolled carbon steel or other common steel products. That classification is the foundation of nearly every trade policy that impacts NOS steel suppliers and buyers.
One of the most impactful trade policies on NOS steel today is the Section 232 tariffs imposed by the United States on steel and aluminum imports back in 2018. For those who don’t remember, Section 232 allows the U.S. government to impose tariffs on imported goods if they’re deemed a threat to national security. At the time, the U.S. targeted steel imports at a 25% rate, and that included NOS steel—even though no one would argue that a specialty alloy for motors poses a national security risk. As a supplier, I watched my U.S.-based customers suddenly face a 25% cost hike on every shipment, pricing them out of bids for commercial electric vehicle projects and HVAC systems they’d won for years. The knock-on effect was worse: some customers shifted their sourcing to domestic NOS steel producers, who had previously been less competitive on price, while others tried to navigate loopholes, like classifying NOS steel under a different tariff code to avoid the charge. It took the U.S. years to adjust the tariff application, and even now, there are ongoing discussions about whether to exempt electrical steel from Section 232, as the Biden administration has signaled it wants to support domestic manufacturing for clean energy projects. For suppliers like me, that uncertainty is costly—we have to build contingency costs into every quote, just in case the tariff landscape shifts again.
Beyond U.S. Section 232, another major trade policy impacting NOS steel is the European Union’s Anti-Dumping Duties (ADD) on imports from China, which were first imposed in 2019 and extended for another five years in 2024. Let’s be clear: this policy was designed to protect EU producers from cheap NOS steel sold below market value by Chinese manufacturers. But as a supplier based in Asia (I won’t name my home country, as that’s not necessary here), I’ve felt the ripple effects. When the ADD went into effect, the duty rate on my NOS steel exports to the EU jumped to nearly 20% for most suppliers. Suddenly, my quotes for European automotive component makers were 20% higher than they were from local producers, even though my product met all the same IEC (International Electrotechnical Commission) standards. Some of my long-term European customers had to pause their orders for months while they renegotiated their own pricing with their end buyers, and a few even switched to European suppliers temporarily. The EU’s policy does have a process for third-country suppliers to prove they’re not dumping, but it requires extensive paperwork, third-party audits, and months of review—something small and medium-sized suppliers like me can rarely afford to do quickly. That’s led to a consolidation in the EU NOS steel market, with only a handful of large producers being able to navigate the anti-dumping rules. It’s a challenge, but it also pushed me to invest in local warehousing in the EU last year, to lower landed costs and avoid the full duty rate. It’s an extra expense, but it’s kept my most important European customers from jumping ship.
Trade blocs have also created both opportunities and barriers for NOS steel suppliers, and the African Continental Free Trade Area (AfCFTA) is a recent example. For years, NOS steel imports into many African countries were subject to high tariffs, sometimes up to 30%, making it too expensive for small-scale manufacturers and renewable energy project developers to source high-quality materials. But since AfCFTA launched in 2021, a growing list of NOS steel products are now eligible for duty-free or reduced-tariff trade across 54 African nations. Last year, I secured a contract with a Kenyan-based electric motor manufacturer for 500 metric tons of NOS steel, and because of AfCFTA rules, I paid only a 5% import duty instead of the 25% standard rate. That made my quote competitive with suppliers from South Africa, who had long dominated the African market. The catch here is that rules of origin are strict under AfCFTA—my steel had to meet specific local content requirements to qualify for reduced tariffs, so I had to work with a local logistics partner to document every step of the supply chain. For suppliers looking to expand into emerging markets, trade blocs like AfCFTA are game changers, but they require paying close attention to detail on documentation.
Another area that’s growing more complex is trade related to clean energy, which is a huge driver of NOS steel demand. The U.S. Inflation Reduction Act (IRA) and the EU’s Net Zero Industry Act (NZIA) both include local content requirements for clean energy projects, and NOS steel is a key component of electric motors and wind turbine generators. For example, under the IRA, a wind turbine project that uses NOS steel produced outside the U.S. can’t access the full 30% tax credit. That’s led many U.S. clean energy companies to shift their NOS steel sourcing to domestic producers, even if that means paying 10-15% more. As a supplier, I’ve had to pivot: I now offer a “localized supply option” for U.S. customers, where we warehouse NOS steel at a facility in Texas and work with a local manufacturer to complete minor finishing processes (like cutting to custom sizes) to meet IRA local content rules. It’s not the same as making the steel in the U.S., but it’s enough to help my customers qualify for the tax credit, and it’s opened up a whole new revenue stream for my business. The flip side is that the NZIA has similar rules, so I’m preparing to set up a small finishing hub in Germany by next year to support European clean energy customers. The clean energy transition is a massive tailwind for NOS steel demand, but the trade policies tied to it mean suppliers have to be flexible, not just good at making steel.
Of course, it’s not all tariffs and restrictions. There are trade policies aimed at streamlining NOS steel supply chains, too. The WTO’s Agreement on Technical Barriers to Trade (TBT) has helped a lot here, because it sets standards for NOS steel quality that are recognized across most major economies. For years, different countries had their own testing requirements for electrical steel, which meant a batch of NOS steel tested in one country might be rejected in another, leading to delays and extra costs. The TBT made it so that IEC standards (for magnetic permeability, thickness consistency, and other properties) are accepted in nearly every market, which has reduced trade barriers significantly. I still keep a copy of my IEC 60401 certification handy for every shipment, because if I don’t include it, customs agents in countries like Brazil or Australia will hold the cargo for weeks waiting for proof of quality. That’s a small step, but it’s made a huge difference in how quickly I can get products to my customers.
As a supplier, I’ll be honest: navigating all these trade policies is exhausting. Every market has different tariff codes, anti-dumping rules, local content requirements, and documentation needs. Last year, I had a shipment of NOS steel bound for India delayed for two weeks because I used the wrong HS (Harmonized System) code, classifying it as “electrical steel for motors” instead of the specific code for “non oriented electrical steel with silicon content between 2.5% and 3.5%.” That delay cost my customer a production slot, and I had to write off 10% of the order to keep their business. It’s a lesson I learned the hard way: trade policy isn’t just a government issue—it’s a daily part of running a NOS steel supply business.
But there’s a bigger picture here, too. NOS steel is critical to the global transition to clean energy, to building more efficient industrial machinery, and to making the appliances that people rely on every day. When trade policies are well-designed, they can level the playing field for suppliers, lower costs for manufacturers, and help get high-quality materials to where they’re needed most. When they’re misaligned, they create barriers that slow down progress and raise costs for everyone.
For anyone in the NOS steel space—whether you’re a manufacturer sourcing material, a project developer building motors or generators, or a supplier like me—staying on top of these policies isn’t optional. It means following updates from trade ministries, working with logistics partners who specialize in specialty steel trade, and building flexibility into your supply chain so you can adapt when rules change.
At the end of the day, my job as a NOS steel supplier isn’t just to make high-quality material that meets magnetic and engineering standards. It’s also to make sure that material gets to my customers on time, on budget, and without unnecessary trade-related costs or delays. If you’re a manufacturer looking for a reliable NOS steel supplier who understands the ins and outs of global trade, who can adapt to changing regulations, and who’s committed to keeping your supply chain running smoothly, don’t hesitate to reach out to discuss your sourcing needs.
