If you import solid aluminum facade panels from China, the tariff line on your landed-cost sheet is no longer a footnote. For many buyers it is now the largest variable in the project budget. There is no single rate: what you pay depends on the product’s classification, which authorities apply, and when the shipment enters the country. This guide explains the layers that can apply and the questions to ask your licensed customs broker before you order.
Tariff policy changes frequently. Rates here reflect public summaries available as of October 2026, given only to frame the conversation with your broker. This is not legal or tax advice — always confirm the duty on your shipment with your licensed customs broker.
Why Tariffs Now Shape Every Aluminum Panel Quote
For years, US buyers could treat duty on Chinese aluminum panels as a predictable, modest line item. That era ended in stages: Section 301 duties on Chinese goods, Section 232 duties on steel and aluminum, a short-lived reciprocal-tariff regime under IEEPA in 2025, and a wholesale restructuring of Section 232 in April 2026. The result is a layered system in which several duties can stack on one shipment — and the classification of your panels can move the bill by tens of percentage points. Budget the tariff line separately and re-verify it per order.
The Layers That Can Apply to One Shipment
One container of aluminum facade panels can attract several separate duties, each with its own legal authority:
- Base MFN duty — the ordinary Most Favored Nation rate in the Harmonized Tariff Schedule (HTSUS).
- Section 301 duties — extra duties on Chinese-origin goods; steel and aluminum products are generally listed at 25%.
- Section 232 duties — national-security duties: 50% on articles wholly of aluminum, 25% on derivatives, on the full customs value since April 2026.
- Anti-dumping and countervailing duties (AD/CVD) — separate orders can apply to specific aluminum products from China, depending on the orders in force.
- The Section 301 forced-labor tranche — a further Section 301 layer since July 24, 2026, replacing the expired Section 122 surcharge; Section 232 goods are generally exempt.
These layers stack in defined ways — and sometimes not at all — so a broker’s confirmation matters more than any general table.
Section 232: The Layer That Matters Most for Aluminum
Section 232 is the duty most likely to dominate the landed cost. Since the April 6, 2026 restructuring, the program is tiered on full customs value: 50% on articles made wholly — or almost wholly — of aluminum, steel, or copper; 25% on derivatives whose foreign metal content exceeds 15% by weight; and no Section 232 duty where non-US metal content is 15% or less. Reduced rates apply in defined cases, such as 10% for derivatives made with at least 85% US-origin metal.
Two details matter: the duty is assessed on the full customs value, not only the metal content. Every entry of covered aluminum must now report where the metal was smelted and cast; the product-exclusion process ended in March 2025.
Section 301 and the Post-IEEPA Landscape
Section 301 duties on Chinese goods remain in force and stack with Section 232 where both apply. For steel and aluminum products, the Section 301 list rate has generally been 25% — so a Chinese aluminum article can face both the Section 232 tier and the Section 301 duty on top of its base MFN rate. The IEEPA reciprocal tariffs that peaked at very high rates for China in 2025 were struck down by the Supreme Court in February 2026. A 10% Section 122 surcharge briefly replaced them, expiring July 24, 2026, when the Section 301 forced-labor tariff took its place — generally 10%, or 12.5% for a list of economies that includes China. Section 232 goods are exempt from that tranche, so it usually adds nothing for panels already in the program. The tariff landscape for Chinese goods has been rewritten three times in less than two years.
Classification: Where the Duty Is Really Decided
For facade panels, the key question is often classification, not the rate table. A solid panel, a perforated panel, a coated panel, and a panel shipped with its fixing system can fall under different HTSUS headings — meaning different duty layers, Section 232 treatment, and AD/CVD exposure. Classification also decides whether your panels count as an “article wholly of aluminum” at the 50% tier or a derivative at 25%. Two shipments of identical-looking panels can attract different duties if their construction, coating, or accessories differ — so experienced importers settle classification with their broker before the purchase order is signed.
Six Questions to Ask Your Licensed Customs Broker
Take this list to your broker:
- What is the correct HTSUS classification for these exact panels — thickness, alloy, coating, perforation, and any fixing hardware shipped with them?
- Which Section 232 tier applies — 50% wholly of aluminum or 25% as a derivative — and does the 15% threshold change anything?
- Which Section 301 list duties apply, and how do they stack with Section 232 and the base MFN rate?
- Are any anti-dumping or countervailing duty orders in force covering these panels?
- What origin documentation is required — including smelt-and-cast declarations — and who must provide it?
- Is a binding ruling worth requesting from US Customs and Border Protection for a recurring specification?
If your broker cannot answer these from the specification alone, the specification needs more detail — alloy grade, coating, dimensions, and scope of supply — before anyone can quote a landed cost.
How to Budget When the Rate Keeps Moving
Until your broker confirms the duty, treat any tariff figure as a planning range. Model two scenarios — the 50% Section 232 tier plus the 25% Section 301 list duty, and the 25% derivative tier plus the same duty — and check whether the project works under the higher one. Keep the tariff line as a separate budget item. Separate the commercial negotiation from the duty question: the factory quotes panels, packing, and freight; only your broker confirms the duty. Duties are assessed as goods enter, not as priced, so re-confirm close to the shipping date.
The Bottom Line
US tariffs are now a layered system: base MFN duty, Section 301 list duties, the Section 232 tier, possible AD/CVD orders, and a policy backdrop rewritten several times since 2025. None of that makes importing impractical — it makes the broker conversation the first step, not the last. Get the classification right, confirm which layers apply, model the high end of the range, and budget the duty as its own line — then the price you negotiate is one you can trust.
