What Are Typical Exceptions That Drive Up Costs?
Learn what 3PL accessorial charges actually cost. Understand relabeling, rework, special handling with real price examples.
You get a quote from a 3PL: "$5.00 CPO, all-in."
You think you are getting $5 per order. Simple.
Six months into the relationship, your invoices are consistently $6.50-7.50 per order.
The 3PL explains: "Your base CPO is $5, but you are triggering several accessorials: oversized items, relabeling, product bundle assembly, and temperature-controlled storage."
You thought you had $5 CPO. You actually have $5 base + $1.50-2.50 in accessorials.
Accessorial charges are the gap between quoted price and actual price. Most brands discover them after signing, when it is too late to negotiate.
This is the guide to understanding what accessorials actually cost, with real examples, so you can forecast them and negotiate them in advance.
## What Are Accessorials?
**Definition:** Charges beyond the base CPO for services or products that require additional handling, labor, or materials.
**Why they exist:**
Not all orders are created equal. Some require extra labor, materials, or space. 3PLs charge extra for these.
**Why they are a problem:**
- Not always disclosed upfront
- Hard to forecast (you might not know you will trigger them)
- Can add 20-50% to your actual cost
- Often discovered after you sign

## The Common Accessorials: With Real Costs
### Accessorial #1: Relabeling
**What it is:**
Your supplier sends inventory with the wrong label or no label. The 3PL must remove the old label and apply a new one with your UPC/barcode.
**When it happens:**
- Supplier label conflicts with your system
- Your UPC is different from supplier's
- Inventory arrives unlabeled
- Private label or rebranding
**Actual cost:**
- Per unit: $0.05-0.20 per unit relabeled
- Per hour (if manual): $25-40/hour
**Real example:**
You receive 5,000 units from a supplier. Supplier labeled them with their brand, you need your UPC. Relabeling 5,000 units at $0.10 each = $500.
If this happens every month: $500/month or $6,000/year on top of your base CPO.
---
### Accessorial #2: Rework (Correcting Errors)
**What it is:**
The 3PL discovers an error in what you sent and must fix it: wrong barcode, missing information, mislabeled product, incorrect packaging.
**When it happens:**
- You send wrong UPCs to the 3PL
- Product arrives mislabeled from supplier
- System mismatch between your system and 3PL system
- You change SKU details after inventory arrives
**Actual cost:**
- Per unit: $0.10-0.30 per unit reworked
- Per hour (if significant): $30-50/hour
**Real example:**
You send inventory with 10-digit UPCs. Your system updated to 12-digit UPCs. The 3PL must relabel or recount everything. Rework on 10,000 units at $0.15 each = $1,500.
If your system changes frequently: $1,500-3,000/month in rework charges.
---
### Accessorial #3: Oversized Item Surcharge
**What it is:**
Items larger than standard bin dimensions require special storage, special handling, or taking up multiple bin locations. 3PLs charge for the extra space or handling.
**When it happens:**
- You sell large products (pillows, blankets, furniture, etc.)
- Item does not fit in standard bin
- Item requires dedicated space
- Item requires special equipment to move
**Actual cost:**
- Per unit: $0.25-1.00 per oversized item per pick
- Or per month: $1-5 per oversized unit in storage
**Real example scenario 1 (Per pick):**
You sell king-size pillows. 500 orders per month with oversized pillows.
Oversized surcharge: 500 orders × $0.50 per oversized item = $250/month = $3,000/year.
**Real example scenario 2 (Per storage):**
You have 1,000 oversized items in storage at any time.
Monthly storage surcharge: 1,000 units × $2/month = $2,000/month = $24,000/year.
---
### Accessorial #4: Product Bundle Assembly / Kitting
**What it is:**
The 3PL assembles multiple items into a kit or bundle (e.g., multi-packs, gift sets, subscription boxes). This requires picking multiple items and assembling them.
**When it happens:**
- You sell bundles (3-pack, 5-pack, gift sets)
- You have subscription boxes with multiple items
- You create custom assortments
- You have promotional bundles
**Actual cost:**
- Per kit: $0.50-2.00 per kit assembled
- Labor intensive if kits are complex
**Real example:**
You sell 500 subscription boxes per month. Each box contains 5 items that must be picked and assembled.
Base picking: 2,500 items picked (500 boxes × 5 items)
Assembly surcharge: 500 boxes × $1.50/box = $750/month = $9,000/year.
---
### Accessorial #5: Temperature/Climate Control
**What it is:**
Products requiring controlled temperature (vitamins, supplements, certain foods, candles). 3PL must store in climate-controlled area (cost, reduced capacity).
**When it happens:**
- You sell supplements or vitamins
- You sell temperature-sensitive foods
- You sell candles (melt in heat)
- You sell anything requiring specific climate
**Actual cost:**
- Monthly fee: $500-2,000/month (for dedicated climate space)
- Or per unit: $0.10-0.50/unit/month storage
**Real example:**
You have 10,000 units of supplements in storage requiring climate control.
Per-unit cost: 10,000 units × $0.25/month = $2,500/month = $30,000/year.
---
### Accessorial #6: Special Labeling / Custom Packaging
**What it is:**
Items requiring custom labels (country-specific, seasonal, personalized) or special packaging (box within box, protective wrapping, custom boxes).
**When it happens:**
- You ship to multiple countries with different labels
- You have personalized products (engraved, custom)
- You require gift wrapping
- You have high-end packaging
**Actual cost:**
- Per unit: $0.20-1.00+ per item
- Depends on complexity
**Real example:**
You sell personalized items. 1,000 orders per month, each requiring custom labeling with customer name.
Custom labeling: 1,000 orders × $0.30 = $300/month = $3,600/year.
---
### Accessorial #7: Hazardous Materials Handling
**What it is:**
Products classified as hazardous (flammables, chemicals, sharp objects, liquids) require special storage, handling, labeling, and documentation.
**When it happens:**
- You sell cleaning supplies
- You sell essential oils or perfumes (flammable)
- You sell sharp items (razors, blades)
- You sell liquids or aerosols
**Actual cost:**
- Monthly fee: $500-2,000/month (for hazmat space)
- Per unit: $0.10-0.50/unit/month
- Or per order: $0.50-2.00/order surcharge
**Real example:**
You sell 500 orders per month of cleaning supplies (hazmat).
Hazmat surcharge: 500 orders × $1.00/order = $500/month = $6,000/year.
Plus monthly hazmat space fee: $1,000/month = $12,000/year.
Total: $18,000/year in hazmat charges.
---
### Accessorial #8: Serialization / Lot Tracking
**What it is:**
Products requiring individual unit tracking (serial numbers) or lot/batch tracking (expiration dates, batch codes). Extra data entry and system tracking.
**When it happens:**
- You sell serialized electronics
- You sell items with expiration dates (food, supplements)
- You have recall risk (food, pharma)
- You need lot-level traceability
**Actual cost:**
- Per unit: $0.05-0.15/unit for serialization
- Or monthly: $500-2,000/month for lot tracking system
**Real example scenario 1:**
You sell electronics with serial numbers. 10,000 units received.
Serialization data entry: 10,000 units × $0.10/unit = $1,000 one-time.
**Real example scenario 2:**
You sell supplements with lot tracking. Ongoing system fee.
Monthly lot-tracking system: $1,500/month = $18,000/year.
---
### Accessorial #9: Quality Control / Inspection
**What it is:**
The 3PL performs receiving inspections, quality checks, or damage assessments beyond standard receiving. This adds labor.
**When it happens:**
- You have high-risk products prone to damage
- Your supplier quality is inconsistent
- You require 100% quality checks (not standard sampling)
- You have high return rates and want to identify root cause
**Actual cost:**
- Per unit: $0.02-0.10/unit inspected
- Per shipment: $50-200/shipment
**Real example:**
You receive 50 shipments per month. Each shipment requires quality inspection.
Inspection fee: 50 shipments × $100/shipment = $5,000/month = $60,000/year.
---
### Accessorial #10: Returns Processing
**What it is:**
Processing returned items (inspection, restocking, refund processing). Beyond simple receiving.
**When it happens:**
- You have retail/marketplace sales (returns are common)
- You have high return rates
- You require quality check on returns before restocking
**Actual cost:**
- Per return: $0.50-2.00 per return processed
- Or per hour: $25-40/hour for return processing
**Real example:**
You have 5% return rate. 5,000 orders/month = 250 returns/month.
Return processing: 250 returns × $1.00/return = $250/month = $3,000/year.
If returns are complex (inspection, testing): 250 returns × $2.00 = $500/month = $6,000/year.
---
### Accessorial #11: Storage Overage / Excess Inventory
**What it is:**
If you exceed your agreed-upon storage allotment, you pay extra for the overflow space.
**When it happens:**
- Inventory builds up unexpectedly
- You do not sell as fast as forecasted
- You add new SKUs
- You prep for peak season
**Actual cost:**
- Per pallet: $100-300/pallet/month
- Per unit: $0.10-0.50/unit/month
**Real example:**
You forecasted 20,000 units storage. You actually store 25,000 units (5,000 units over).
Overage at $0.20/unit/month: 5,000 units × $0.20 = $1,000/month = $12,000/year.
---
### Accessorial #12: Rush/Expedited Processing
**What it is:**
Processing orders faster than standard SLA (same-day pick/pack instead of next-day, weekend processing, holiday processing).
**When it happens:**
- You need emergency shipments
- You have flash sales that spike volume
- You need inventory shipped before a deadline
- You run seasonal campaigns
**Actual cost:**
- Per order: $0.50-5.00/order premium
- Per hour: Time-and-a-half labor
**Real example:**
You run a flash sale: 2,000 orders need to ship same-day instead of next-day.
Rush surcharge: 2,000 orders × $1.00/order = $2,000 (one-time).
If you do this monthly: $2,000/month = $24,000/year.
---
## How These Add Up: Real Example
Let me show you how accessorials compound.
**Your business:**
- 10,000 orders/month
- 50,000 units stored
- Mix of standard items, some oversized, some bundles, some require temperature control
- Supplements (serialized, temperature-controlled)
**Quote promised:** $5.00 CPO "all-in"
**Actual charges:**
| Accessorial | Calc | Monthly | Annual |
|---|---|---|---|
| Base CPO | 10,000 × $5.00 | $50,000 | $600,000 |
| Oversized (10% of orders) | 1,000 × $0.50 | $500 | $6,000 |
| Bundle assembly (20% of orders) | 2,000 × $0.75 | $1,500 | $18,000 |
| Temperature control storage | 20,000 units × $0.20/month | $4,000 | $48,000 |
| Serialization | 5,000 units/month × $0.10 | $500 | $6,000 |
| Quality inspection | 10 shipments × $100 | $1,000 | $12,000 |
| Returns processing (3% rate) | 300 returns × $1.00 | $300 | $3,600 |
| **TOTAL** | | **$57,800** | **$693,600** |
**Your actual cost:** $5.78/order, not $5.00
**Overage:** $93,600/year or $7.80/order
**That is a 156% increase from quoted price.**

## How to Forecast Accessorials Before Signing
### Step 1: Audit Your Current Operation
What exceptions do you currently have?
- What % of items are oversized?
- What % are bundles/kits?
- Do you have temperature-sensitive items?
- Do you have hazmat?
- Do you have serialized items?
- What is your return rate?
- Do you do rush orders?
**Real data:** Track your actual operation for 4 weeks. Calculate percentages.
---
### Step 2: Create an Accessorials Checklist
For each potential accessorial, ask:
- Do we have this? (Yes/No)
- What % of orders/units? (If yes)
- Estimated cost per unit? (Ask 3PL)
- Annual impact? (% × volume × cost)
---
### Step 3: Calculate Your Real CPO
Base CPO + (Accessorials % × Accessorial Cost) = Real CPO
**Example:**
- Base CPO: $5.00
- Oversized surcharge: 10% × $0.50 = $0.05
- Bundle assembly: 20% × $0.75 = $0.15
- Temperature control: 10% of units × $0.20 = $0.02
- Returns: 3% × $1.00 = $0.03
- **Real CPO: $5.25**

## Red Flags: Unreasonable Accessorial Charges
Watch for accessorials that seem high:
### Red Flag #1: Oversized Charge Per Pick >$1.00
**Why it is high:**
Handling an oversized item takes maybe an extra 30 seconds. At $25/hour labor, that is about $0.20. Charging $1.00+ is excessive.
**What to do:**
Push back. "That seems high. What is the actual labor cost? Can you show me the calculation?"
---
### Red Flag #2: Hazmat Charge >$2.00 Per Order
**Why it is high:**
Hazmat storage is expensive, but handling cost per order should not be excessive. $2/order adds up fast.
**What to do:**
Negotiate. "What if we consolidate hazmat shipments? Can you reduce the per-order cost?"
---
### Red Flag #3: Returns Charge >$2.00 Per Return
**Why it is high:**
Processing a return (inspect, rescan, restock) should take 5-10 minutes. At $25-30/hour, that is $2-5 in labor. Charging $2-3 per return is on the high end.
**What to do:**
Negotiate. "Can you process returns for under $1.50 per return? That is our benchmark."
---
### Red Flag #4: Temperature Control > $0.30/Unit/Month
**Why it is high:**
Climate-controlled space costs money, but even expensive climate control is usually $0.15-0.25/unit/month. Higher is excessive.
**What to do:**
Shop around. Other 3PLs might offer climate control cheaper.
---
### Red Flag #5: Vague Accessorial List
**What it looks like:**
"Miscellaneous charges apply as needed" or "Other charges per complexity."
**Why it is a red flag:**
You cannot forecast. They can charge anything after you sign.
**What to do:**
Demand specificity. "List every possible charge with examples. If there are charges beyond this list, they require written approval from us first."
---
## How to Negotiate Accessorial Caps
Before you sign, negotiate caps on accessorials:
### Cap #1: Per-Order Accessorial Cap
"Total accessorial charges will not exceed $[X] per order in any given month. Anything above that requires written approval from us in advance."
Example: "$1.50 per order in accessorials maximum."
---
### Cap #2: Total Accessorial Budget
"Total accessorial charges will not exceed $[X] per month. If actual exceeds this, you will absorb the overage."
Example: "$5,000/month in accessorial charges maximum."
---
### Cap #3: Per-Item Accessorial Limits
"Specific charges will not exceed: oversized $0.50/item, temperature control $0.25/unit/month, serialization $0.10/unit, hazmat $1.00/order"
---
### Cap #4: Approval Required for Unexpected Charges
"Any accessorial charges we have not discussed and agreed to in writing require our written approval before you incur them. Unapproved charges will not be paid."
---
## Questions to Ask in Your RFP
Make sure your RFP captures all potential accessorials:
### Question: "Please List All Possible Accessorial Charges"
Ask them to list:
- Every possible charge
- Cost per unit/order
- When it applies
- Example scenarios
Then review and negotiate.
### Question: "What % of Your Clients Incur Each Accessorial?"
This reveals:
- How common the charge is
- Whether they charge most people
- How predictable it is
If they say "90% of clients incur temperature control," that is a hidden default cost.
### Question: "Can We Set Accessorial Caps or Limits?"
See if they are willing to negotiate maximum charges.
If they refuse: Red flag. They want flexibility to charge you more.
---
## The Bottom Line: Accessorials Are How 3PLs Make Money
Here is the truth: 3PLs quote low CPO, then make their margin on accessorials.
A $5 CPO that becomes $7.50 after accessorials is a bait-and-switch.
The solution:
1. **Audit your operation** — Know what you will trigger
2. **Forecast accessorials** — Calculate your real CPO
3. **Ask specific questions** — Get detailed accessorial lists
4. **Negotiate caps** — Set maximum charges upfront
5. **Require approval** — Any surprise charges need your permission
A good 3PL will be transparent about accessorials and willing to cap them.
A bad 3PL will keep the list vague and resist caps.
The difference between a good quote and a bad one is often not the CPO — it is whether the accessorials are transparent and capped.
