Aluminum Composite Panel for US Projects: Buyer’s Guide
Buying aluminum composite panel for a US project is not the same exercise as buying it for most other markets. In most markets the deciding question is the price per square metre. In the US the deciding question is whether three things hold up at once: the panel against the building code, the wall assembly against the fire test the code names, and the shipment against US Customs. A panel that is cheap and fails any one of those is not a cheap panel — it is an order you have to pull back off the wall. This guide takes them in the order they will actually stop a project.
The short answer
Let the building code pick the core, not the budget. Get the coating specified to AAMA 2605 if the facade has to hold its colour for two decades. Sort the HTS classification and the duty position with your customs broker before you place the order, not after it lands. Everything below is detail on those three.
1. Start from the code, not from the brochure
The US regulates aluminum composite panel as Metal Composite Material (MCM), and the governing provision is the International Building Code. Two thresholds decide almost every facade question you will be asked:
- The 40-foot line. On buildings of Type I, II, III or IV construction, MCM is generally permitted up to 40 feet (12.2 m) above grade before compliance with NFPA 285 comes into play. Above that, the assembly has to demonstrate compliance.
- The foam plastic trigger. If the wall build-up contains foam plastic insulation — board stock or a component — the assembly must comply with NFPA 285 at any height, not just above 40 feet. This is the condition that catches most projects, because mineral wool is often swapped in precisely to avoid it.
One thing is worth stating plainly because it is misquoted constantly in quotations: NFPA 285 is a test of the wall assembly, not of the panel. It evaluates how fire propagates across a specific combination — cladding, insulation, air barrier, sheathing, flashing, substrate. No panel carries “NFPA 285 certification” on its own, and a supplier who tells you it does has misunderstood the standard or is hoping you have. What a panel manufacturer can give you is the fire-performance data for the panel, for the wall-system designer to put into their assembly test and their submission.
ASTM E84 is the other test you will see quoted. It measures surface burning characteristics — Class A means a flame spread index of 25 or less and a smoke-developed index of 450 or less. It is a material surface test. It is not a substitute for NFPA 285, and passing E84 does not make an assembly compliant.
2. Then choose the core against that code
There are three cores, and the code treats them differently:
- PE (polyethylene). The standard core. Combustible, and the core type behind the facade fire cases that reshaped US cladding rules. Fine for low-rise and for uses the code permits at the height you are building; not the core to design a high-rise facade around.
- FR, often sold as “B1”. Mineral-filled, fire-retardant, still technically combustible but the common route to an assembly that passes NFPA 285. If your facade is above 40 feet and the assembly is being tested, this is usually the core in it.
- A2. Mineral-filled to limited combustibility (EN 13501-1 A2–s1,d0). Specified when the design wants the panel itself to contribute as little fuel as possible — and where the alternative is arguing about the assembly at all.
If you are weighing these against a specification, we compared them side by side in PE vs FR (B1) vs A2 core.
3. Coating: AAMA 2605 is the number that matters here
Outside the US, coating is usually argued in microns of dry film thickness. In the US the specifier names a voluntary standard instead, and the one that matters for a facade is AAMA 2605, Superior Performing Organic Coatings on Aluminum Extrusions and Panels.
In practice AAMA 2605 means a colour coat with at least 70% PVDF resin by weight — normally Kynar 500 or Hylar 5000 — over a primer on properly pretreated aluminium, and it comes with performance thresholds a lower grade does not: ten years of South Florida exposure with no more than 5 Delta E units of colour change and at least 50% gloss retention, 4,000 hours of humidity resistance, and 2,000 hours of cyclic corrosion testing. AAMA 2604 (five-year) and AAMA 2603 (one-year) are the lower tiers; they are legitimate products, but if your specification says 2605 and the quote came back on 2604, that is the gap.
If the finish is still open, PVDF vs polyester for ACP covers where each one earns its cost.
4. Write the specification in inches
A US specification that is silent on units gets quoted two different ways, and the difference is real. Convert deliberately:
- Panel thickness — 3 mm (0.118 in), 4 mm (0.157 in), 6 mm (0.236 in). 4 mm is the default for facade work.
- Aluminium skin — 0.21 / 0.30 / 0.40 / 0.50 mm (0.008 / 0.012 / 0.016 / 0.020 in). This single number moves cost more than any other, and it also determines the tariff classification — see below.
- Panel size — 1220 × 2440 mm is the familiar 4 × 8 ft sheet; 1500 × 3050 mm is 5 × 10 ft. Widths run up to 2 metres (78.7 in) on a wide line, which changes what you can fabricate without a joint.
5. The import position: HTS and Section 232
This is the part that most often surprises first-time US buyers, because the tariff exposure on aluminium composite panel is not a small percentage.
Classification. US Customs treats ACP as a composite good whose essential character comes from the aluminium, so it classifies in Chapter 76 by the thickness of the aluminium skin. Above 0.2 mm the panel falls in heading 7606 (aluminium plate, sheet and strip); at or below 0.2 mm it moves to heading 7607 (aluminium foil). The base Column 1 rate in 7606 has been around 3% ad valorem. Practical consequence: the skin thickness you choose in section 4 is also a classification decision, so decide it with your broker in the room.
Section 232. Aluminium imports are subject to the Section 232 national-security tariff, reported with a Chapter 99 heading on the entry. Headings 7601, 7604, 7605, 7606, 7607 and 7608 have all been covered. The regime was restructured through 2026 into a value-based tiered system, with products moving between tiers depending on how close they sit to primary aluminium, and country-specific arrangements layered on top. We are not going to print a rate here that will be stale by the time you read it: the point is that the duty on an ACP entry is a multiple of the panel price, not a rounding error, and it is calculated on the full customs value of the finished article, not only on the metal content.
What to do about it. Get a written classification from your customs broker before you commit to a price, and get them to state the Chapter 99 treatment and any anti-dumping or countervailing exposure that attaches to that classification and that country of origin. Then price the landed cost, not the FOB number. The mechanics are the same as any other market — we walked through them in how to import ACP from China — but in the US the duty lines are larger, so the arithmetic matters more.
6. Documents worth having before the container ships
- ISO 9001 certificate for the manufacturing plant.
- Alloy and mill certificates for the coil the skin came from.
- ASTM E84 report for the actual core and skin build you are buying.
- Coating data showing the resin system and the AAMA grade it was qualified against.
- Packing list and commercial invoice whose specification matches section 4 line for line.
- Whatever your wall-system designer needs for the NFPA 285 submission — raise this at quotation stage, because it is their assembly and their test.
Ask which of these the factory issues as standard and which take extra lead time. A supplier who cannot produce a fire test report for the specific core they are selling you is telling you something.
Frequently asked questions
Can I use PE-core aluminum composite panel in the US?
Yes, within the code. PE core is combustible, and the IBC restricts it on Type I–IV walls above 40 feet and requires a tested assembly where foam plastic insulation is present. Below those thresholds, and in low-rise construction, it is used routinely. The mistake is treating PE as a price decision rather than a code decision.
Does the panel need NFPA 285?
The assembly does, not the panel. NFPA 285 tests a specific wall build-up. What you need from the panel supplier is the fire-performance data for that component, so the wall-system designer can put the assembly forward for testing and approval by the authority having jurisdiction.
What HTS code applies to aluminum composite panel?
Chapter 76, by aluminium skin thickness: heading 7606 above 0.2 mm and 7607 at or below it, with the specific subheading depending on alloy, cladding and thickness. Because the classification drives both the base rate and the Section 232 treatment, have your broker classify the actual product rather than a description of it.
What is the lead time to the US?
Production is normally 10 to 15 days after the deposit for a standard specification. To that you add ocean transit and the customs-clearance window at your port. Special cores, special colours and pre-shipment documentation each add their own time, so raise them at quotation rather than after the order is confirmed.
Do you supply Miami-Dade or coastal approvals?
Coastal and high-wind jurisdictions have their own product-approval requirements, and whether a given product holds the approval your project needs is specific to the product and the jurisdiction. Tell us the project location and we will tell you honestly which documentation we can issue and which we cannot, rather than let it surface at submittal.
