One of the things I love about aluminum extrusion is the sheer variety of shapes we can make. Even before a profile is cut, machined, welded, or built into an assembly, it may look nothing like what someone pictures when they hear the word “extrusion.” At the border, it might be described accurately as a machine part, and depending on what’s being imported, it might enter under any number of Harmonized Tariff Schedule (HTS) codes. But the process that made the profile hasn’t changed. Recognizing an extrusion for what it is, even when the paperwork calls it something else, was one of the most important lessons of our training at Custom Aluminum Products.
On November 4, AEC and Custom Aluminum hosted the Aluminum Extrusion Identification, Classification, and Trade Law Seminar in Genoa, Illinois. Nearly 100 people registered, including U.S. Customs and Border Protection (CBP) and other federal officials, importers, and customs brokers. We put real parts in people’s hands so they could see the range of applications for extrusions, recognize a profile inside an assembly, and understand what the documentation for an imported product should show.
For AEC, this was more than a chance to explain how an extrusion is made. It was a chance for the people who make the product, the people who import it, and the officers who enforce the rules to look at the same parts and talk through the same questions. That shared understanding helps CBP spot entries that warrant a closer look and helps importers and brokers know what to document to get an entry right. Trade rules are only as effective as our ability to apply them consistently at the border. That’s why we put so much into this training, and why conversations are already underway about additional training in 2027.
Thank you to the AEC members who contributed their time, expertise, and samples. And a heartfelt thank-you to everyone at Custom Aluminum for opening your facility to us and doing the work to organize the event. There’s no substitute for learning about extrusions in a plant where they’re made.
Why the Heat Exchanger Ruling Matters to U.S. Extruders
Commerce gave us a timely example of why this training matters. On October 15, the U.S. Department of Commerce ruled that the Sanhua microchannel heat exchangers at issue are covered by the existing antidumping and countervailing duty orders on aluminum extrusions from China. Commerce applied the ruling on a country-wide basis rather than limiting it to a single importer.
Here’s why this matters even if you’ve never made a microchannel heat exchanger. In this case, extrusions made in China were shipped to Mexico, assembled into heat exchangers, and then entered the United States as products of Mexico. Commerce found that the heat exchangers at issue were still covered by the China extrusion orders. In other words, assembling those Chinese extrusions into heat exchangers in Mexico did not put them outside the scope of the orders.
Even more important, Commerce is applying this ruling country-wide, not just to one company. That matters for a few reasons. Commerce leans on past rulings when it decides new ones, so this reasoning will shape how other assemblies are treated, from heat sinks to automotive and building products. Assemblies are also a common path for avoiding duties, and when that path stays open, demand quietly drains away from extruders in every market. Clear rulings give CBP a firm line to enforce, which is exactly what our seminar attendees told us they need.
As we know, extrusions don’t normally show up at the border as a shipment of bare profiles. They can come in as components or assemblies, under a different tariff code, after work in another country. This ruling matters because it shows that the existing orders can still reach covered merchandise in that situation. For U.S. extruders competing for that business, that’s a meaningful enforcement result.
The seminar and the ruling make the same point in different ways: you have to know what you’re looking at before you can apply the right rule. Helping people make that connection is a practical way AEC can strengthen fair trade enforcement for the whole industry.
