SECTION 232 AUTO PARTS TARIFFS ARE LIVE — WHAT IMPORTERS NEED TO KNOW ABOUT DRAYAGE AND FREIGHT COSTS RIGHT NOW
On April 1, 2026, the 25% Section 232 tariff on auto parts entered full enforcement. This is not an announcement of future policy — it is a live cost event that changed your landed economics at midnight.
If your business imports auto parts from Japan, Korea, Taiwan, Germany, or any other non-exempt country, the per-shipment cost of getting that freight from port to warehouse increased materially. The tariff itself is a fixed cost you cannot negotiate away. But the freight costs surrounding it — drayage, fuel surcharges, detention, per diem, and inland transport — are costs you can manage.
This guide covers what changed on April 1, what the real-world freight cost impact looks like, and the three specific actions auto parts importers should take this week.
What Section 232 Means for Auto Parts Importers
Section 232 of the Trade Expansion Act of 1962 authorizes tariffs when imports are determined to threaten national security. The 25% tariff on auto parts from non-exempt countries is now fully enforced.
What qualifies as "auto parts" under Section 232: The scope covers passenger vehicle and light truck parts across a broad range of HTS codes — engines, transmissions, body stampings, electrical components, powertrain parts, and drivetrain assemblies. In March 2026, the scope expanded to include medium and heavy-duty vehicles, parts, and buses.
USMCA exemption: Parts with sufficient North American content sourced from Canada or Mexico under USMCA are exempt from Section 232. Parts meeting U.S. content thresholds may also qualify for reduced exposure. If you source from Mexico or Canada, confirm your USMCA certification is current — this is your primary tariff offset.
Tariff stacking: Section 232 does not replace other active tariffs. It stacks on top of them. Importers from non-exempt countries currently face Section 232 (25%) plus Section 122 (10% global surcharge active through July 24, 2026). For parts from countries under USTR Section 301 investigation — including Japan, Korea, and Taiwan — the combined tariff burden can reach 35% or higher before any duty drawback or offset programs apply.
Manufacturer offset program: Auto manufacturers may apply for an import adjustment offset equal to 3.75% of aggregate MSRP for U.S.-built vehicles through April 30, 2026, dropping to 2.5% thereafter. Important: this offset is generally available only to vehicle manufacturers, not parts distributors or independent importers. If you are a parts distributor, do not assume you qualify.
What It Costs to Move Auto Parts from Port to Warehouse Right Now
Drayage is the first and last physical cost event in an auto parts import. It is where tariff pressure, fuel costs, and capacity constraints converge into a single invoice.
Diesel at $5.40/gallon. Fuel surcharges on drayage moves are running at elevated levels nationally. The March diesel spike driven by the Hormuz oil supply disruption has not corrected. Every drayage quote older than 45 days was priced in a different fuel environment.
Tender rejections at 14%. Carriers are selective. Auto parts importers competing for the same drayage trucks as furniture and electronics importers during the Q2 front-loading surge face real capacity constraints. A shipment that gets rejected at first tender costs more to cover on the second or third attempt — and it sits at the terminal accumulating per diem while you find a truck.
Practical cost model for a 40-foot container at LA/Long Beach (Spring 2026):
- Base drayage: $475–$650
- Fuel surcharge (at current diesel): +$180–$240
- Chassis fee: +$50–$80/day if not returned same-day
- Per diem: +$75–$150/day after free time (steamship line varies)
- Total all-in cost: $800–$1,200+ per container move — before the tariff cost is factored in
On a $50,000 auto parts shipment, the 25% Section 232 tariff alone adds $12,500 in duty. Proper freight coordination — minimizing terminal dwell time, eliminating accessorial charges, securing capacity before spot market premiums kick in — can recover hundreds of dollars per container move. That does not offset $12,500, but it is the difference between managing costs and letting them compound.
The April 1–14 Inclusions Window — Review Your HTS Codes This Week
The Bureau of Industry and Security (BIS) opened an inclusions window from April 1–14, 2026. During this window, any party can submit a request to add additional auto part HTS codes to the Section 232 scope.
This matters for your freight planning because if a code you currently import is submitted for inclusion and approved, the 25% tariff could apply to future entries — potentially affecting shipments already in transit.
What to do right now:
- Have your customs broker pull every HTS code for auto parts you currently import
- Cross-reference each code against the existing Section 232 parts list on CBP.gov
- Flag any codes that are adjacent to existing inclusions — these are highest-risk for future inclusion
- If you have codes that should NOT be included, submit exclusion requests before April 14 (send to AutoInclusions@trade.gov)
Freight implication: If you expect certain part categories to be added to Section 232 scope after April 14, a pull-forward of those SKUs before the determination may be cost-justified. That means Q2 drayage demand for auto parts could spike beyond what current front-loading projections suggest.
Three Freight Actions Auto Parts Importers Should Take This Week
1. Re-baseline your drayage pricing against current diesel
If your drayage quotes are more than 45 days old, they were priced before the March diesel spike. Rates set in January or February 2026 are materially underpriced relative to what carriers will accept today. A contract that looks favorable on paper but results in tender rejections or service failures is worse than no contract. Get your fuel surcharge schedule re-baselined against the current DOE diesel index now.
2. Lock Q2 capacity at your primary ports
Auto parts importers using LA/Long Beach, Houston, Newark, or Savannah will be competing for the same drayage capacity as every other importer pulling volume forward before the July 24 Section 122 expiration. The carrier who fills your spot today will not be available on the spot market in June. Position your Q2 capacity commitments in April — not May.
Houston is particularly important for auto parts importers: UP on-dock rail at Barbours Cut is now active with routing to Denver, LA, and El Paso. If you have not evaluated Houston intermodal for inland auto parts distribution, the current rate environment makes it worth a serious look.
3. Evaluate intermodal for inland legs over 500 miles
If your auto parts move from port to a distribution center more than 500 miles inland — Chicago, Dallas, Memphis, Atlanta, Denver — the mode-spread math strongly favors intermodal at current rates. Intermodal spot is running at approximately $1.39/mile versus $2.80/mile for truckload on comparable lanes.
A non-asset freight broker who coordinates drayage on both ends of the intermodal move — port-to-ramp plus ramp-to-DC — eliminates the handoff risk that asset carriers cannot solve. The savings on a single Chicago-bound auto parts container can exceed $1,000 per move versus over-the-road.
How Alliance Freight Solutions Can Help
Alliance Freight Solutions is a licensed non-asset freight broker (MC-1607949, DOT-4177688) specializing in port drayage and intermodal coordination for U.S. importers.
We cover the ports where auto parts volume concentrates: LA/Long Beach, Houston, Savannah, Newark, Seattle/Tacoma, and Miami. Our non-asset model means we select the right carrier for each move based on current capacity and pricing — not default to available fleet.
For auto parts importers navigating Section 232, Section 122, and Section 301 simultaneously, the complexity of current trade policy requires a broker who understands how tariff timing affects freight timing. We track carrier fuel surcharge schedules, port chassis availability, and terminal dwell conditions weekly so you do not have to.
