LTL Freight Cost Spike Analysis: Q1 vs Q2 2025
Cost Increase Summary
| Metric | Q1 2025 | Q2 2025 | Change |
|---|---|---|---|
| Avg Cost per Shipment | $881.32 | $1268.53 | +43.9% |
| Total Shipments | 95 | 98 | +3.2% |
| Avg Weight (lbs) | 2122 | 2218 | +4.5% |
| Monthly Spend | $27,908/mo | $41,439/mo | +$13,530/mo |
Your shipping profile is essentially unchanged. This is a rate-driven problem.
Root Cause Breakdown
Root Cause #1: Reclassification Fees (18% of increase)
Impact: +$69.28 per shipment | +$2,263/month
| Quarter | Shipments with Reclass | Avg Fee | % Affected |
|---|---|---|---|
| Q1 | 3 of 95 | $2.67 | 3.2% |
| Q2 | 73 of 98 | $71.94 | 74.5% |
Cause: April 1, 2025 NMFC code updates reclassified 50%+ of commodity codes.
Common reclassifications observed in your data:
- Class 70 items -> Class 85 (+21% rate base)
- Class 85 items -> Class 92.5 (+16% rate base)
- Class 92.5 items -> Class 100 (+11% rate base)
This explains the dramatic jump from 3.2% to 74.5% of shipments being reclassified.
Root Cause #2: Fuel Surcharges (23% of increase)
Impact: +$90.75 per shipment | +$2,965/month
| Quarter | Avg Fuel Surcharge | % of Total Cost |
|---|---|---|
| Q1 | $104.51 | 11.9% |
| Q2 | $195.26 | 15.4% |
Diesel prices rose from $3.82/gal (Jan avg) to $4.51/gal (May avg) = +18.1%
Root Cause #3: Base Rate Increases (59% of increase)
Impact: +$227.19 per shipment | +$7,422/month

Optimization Recommendations
Priority 1: Challenge Freight Classifications
Potential Savings: $950/month | $11,405/year
74% reclassification rate is exceptionally high and suggests many items may be misclassified.
Actions:
- Request detailed reclassification justification from carriers for top 20 highest-fee shipments
- Measure actual density (lbs per cubic foot) for commonly shipped items:
- Class 85: 8-9 lbs/cu ft
- Class 92.5: 7-8 lbs/cu ft
- Class 100: 6-7 lbs/cu ft
- If items exceed density thresholds, submit NMFC classification appeals
- Work with packaging team to increase density where possible
Expected recovery: 35-50% of reclassification fees
Priority 2: Negotiate Reclassification Protection
Potential Savings: $792-$1,245/month
Your Q2 annual run rate is $497,266 with carriers. Use this leverage.
Negotiation points:
- Request: Freeze rates for specific SKUs/commodity codes despite NMFC changes
- Offer: 12-month volume commitment at current levels (392 annual shipments)
- Benchmark: Share quotes from competing carriers for same lanes
- Target: 30-55% reduction in reclassification fees
Carriers to prioritize: XPO and Old Dominion (your highest volume)
Priority 3: Optimize Packaging for Density
Potential Savings: $2,078/month | $24,937/year
Increasing density by 10-15% can shift freight class down one tier.
Actions:
- Audit pallet stacking patterns - reduce void space
- Test smaller pallet sizes (40x48 vs 48x48) for lighter loads
- Consider double-stacking compatible items
- Target: Move 25-30 shipments/month down one freight class
Example: Class 92.5 -> Class 85 saves ~$85/shipment
Priority 4: Fuel Surcharge Caps
Potential Savings: $741/month (if diesel stays elevated)
Action: Negotiate fuel surcharge caps at 18-20% of base rate in next contract renewal.
Current surcharges at 15.4% are high but reflect market diesel prices.
Priority 5: Route Optimization Analysis
Potential Savings: $2,486/month
Action: Request quote from regional carriers for your top 3 destination states.
Regional carriers often offer 8-15% lower rates for shorter haul distances (under 800 miles).
Total Recovery Potential
| Recommendation | Monthly Low | Monthly High | Difficulty |
|---|---|---|---|
| Challenge Classifications | $792 | $1,131 | Medium |
| Negotiate Reclass Protection | $679 | $1,245 | Low-Medium |
| Packaging Optimization | $1,484 | $2,598 | Medium-High |
| Fuel Surcharge Caps | $593 | $889 | Low |
| Route Optimization | $1,658 | $3,315 | Medium |
| TOTAL | $5,206 | $9,178 | - |
Recovery: 38%-68% of the $13,530/month increase
Implementation Timeline
This Week (Immediate Actions)
- Request reclassification documentation from all carriers for shipments with fees >$85
- Measure density of your 5 most frequently shipped items
- Compile Q1 vs Q2 data to present to carriers showing cost impact
Next 2 Weeks (Quick Wins)
- Submit classification appeals for items that meet lower class density requirements
- Contact account managers at XPO and Old Dominion to schedule rate review meetings
- Audit packaging for top 10 highest-cost lanes
This Month (Strategic Changes)
- Formal carrier negotiations with prepared data showing:
- $497,266 annual spend
- Competitive quotes from regional carriers
- Specific SKU rate freeze requests
- Packaging pilot program testing denser configurations on 25 shipments
- Request quotes from regional carriers for IL/OH/MI destinations
Next 30-60 Days (Long-term Optimization)
- Implement new packaging standards if pilot successful
- Execute contract amendments with improved terms
- Set up monthly monitoring of reclassification fees and fuel surcharges
Key Takeaway
The 44% cost increase is NOT due to shipping more or changing your logistics. It’s driven by:
- Industry-wide NMFC reclassification (18% of increase) - affects everyone, but you can fight it
- Diesel price surge (23% of increase) - market-driven, limited control
- Annual GRI (59% of increase) - negotiable with your volume
Focus your energy on challenging classifications and negotiating rate protections. These offer the highest ROI for your time.
