Section 232 Now Applies to Full Customs Value — Furniture, Appliances, and Auto Parts Hit Hardest
Most coverage of the April 6 Section 232 metals restructure focused on the headline rate jump from 25% to 50%. But there's a quieter change buried in the proclamation that may hit derivative product importers even harder: Section 232 duties are now assessed on the FULL customs value of derivative products, not just the metal content portion.
If you import furniture with metal frames, appliances with metal housings, auto parts with steel components, or industrial equipment with copper wiring — your duty bill just exploded.
The Old Methodology
Before April 6, 2026, Section 232 tariffs on derivative products worked like this:
You imported a $1,000 piece of furniture with $200 worth of steel components. The Section 232 duty (25% at the time) applied to the steel content only:
Old calculation:
$200 metal content × 25% = $50 in Section 232 duty
You declared the metal content value on your commercial invoice, and that's what got taxed.
The New Methodology
Effective April 6, 2026, the proclamation overrides that approach. Section 232 duties now apply to the entire customs value of the imported good:
New calculation:
$1,000 full customs value × 25% = $250 in Section 232 duty
That's a 5x increase in Section 232 duty on the same product, with no change in actual metal content. Multiply this across thousands of furniture, appliance, and auto parts shipments per year, and you're looking at billions in additional duties.
The New Rate Structure
The proclamation creates a tiered system based on metal content:
| Article Category | Rate | What It Means |
|---|---|---|
| Steel/aluminum/copper articles (Annex I-A, HTS 9903.82.02) | 50% | Made entirely or almost entirely of these metals |
| Derivative products (Annex I-B) | 25% | Substantially made of these metals |
| Reduced rate for US-content products | 10% | Made abroad using exclusively American-smelted metals |
| Products with less than 15% metal by weight | Exempt | Carve-out for low-metal-content goods |
Important correction: The 15% threshold is measured by weight, not value. And HTS Chapters 72-76 articles remain covered regardless of metal content percentage.
Who's Hit Hardest
This valuation methodology change affects industries that import goods with metal components but where the metal isn't the primary value:
Furniture (HTS Chapter 94) — Sofas with metal frames, kitchen cabinets with metal hardware, office chairs with metal bases. Furniture importers were already absorbing tariff costs from previous rounds. The full-customs-value methodology makes Section 232 a much bigger line item.
Appliances (HTS Chapter 84-85) — Washing machines, refrigerators, dishwashers, microwaves. Even though the metal content is a fraction of the total value, the duty now applies to the full value.
Auto parts (HTS Chapter 87) — Brake systems, transmissions, suspension components, body panels. Already under separate tariff pressure, now compounded by the 232 valuation change.
Industrial equipment (HTS Chapter 84) — Machinery, transformers, switchgear, pumps with copper windings.
Construction materials (HTS Chapter 73, 76) — Prefab structures, scaffolding, fasteners.
Dollar Impact Examples
Example 1: Mid-priced living room sofa from Vietnam
Customs value: $800
Metal content: ~$120 (15% by value, exempt under old rules)
OLD METHODOLOGY:
$120 × 25% = $30 Section 232 duty
NEW METHODOLOGY:
$800 × 25% = $200 Section 232 duty
INCREASE PER SOFA: $170 (567% jump)
For an importer bringing in 5,000 sofas per year, that's an additional $850,000 in duties annually — purely from the valuation methodology change.
Example 2: Commercial dishwasher from Germany
Customs value: $4,200
Metal content: ~$1,000 (24% by value)
OLD METHODOLOGY:
$1,000 × 25% = $250 Section 232 duty
NEW METHODOLOGY:
$4,200 × 25% = $1,050 Section 232 duty
INCREASE PER UNIT: $800 (320% jump)
A restaurant equipment distributor importing 200 commercial dishwashers per year sees an additional $160,000 in annual duties from this single product line.
What You Should Do
-
Recalculate your landed costs immediately. Every product with metal components needs new duty math. The old commercial invoice valuation approach is dead.
-
Check the 15% weight threshold. If your products genuinely have less than 15% metal content by weight (and aren't in HTS Chapters 72-76), they're exempt. Get a detailed weight breakdown from your supplier.
-
Talk to your customs broker about reclassification. Some products may be reclassifiable under HTS codes that fall outside Section 232 scope. This requires expert analysis — don't guess.
-
Update your pricing. A duty cost that just jumped 5x has to be reflected in your selling prices or absorbed from margin. Most small importers can't absorb this. Pass it through quickly.
-
Look for US-sourced metal alternatives. Products made abroad using exclusively American-smelted metals get the reduced 10% rate. If your supplier can document US metal sourcing, you save 15-40 percentage points.
-
Watch for additional carve-outs. The proclamation includes various exclusion provisions for specific industries. Check the CBP CSMS bulletin for product-specific guidance.

The full operational guidance is in CBP CSMS message #68253075 ("GUIDANCE: Section 232 Duties on Imports of Aluminum, Steel, and Copper"). Your broker should have this. If they're still calculating duties on metal content only, they're using the old methodology and your entries will be flagged.
