Storage-in-Transit Moving Cost 2026
Storage-in-transit moving cost 2026 can be estimated as shipment hundredweight multiplied by the monthly storage rate, plus warehouse handling, redelivery, valuation, and taxes. Using Washington's currently effective maximum intrastate benchmark through July 31, 2026, a 7,000-pound shipment at about $9.34 per 100 pounds per 30 days costs about $654 for one storage period; two handling events at about $14.33 per 100 pounds each add about $2,006 before redelivery or other charges.
That example reveals the common surprise: moving into and out of a warehouse can cost more than one month of storage. Enter the exact rates from your estimate or tariff in the calculator. Never transfer a state tariff example to an interstate shipment without confirming the governing documents.
How Storage-in-Transit Charges Work
Storage-in-transit, usually shortened to SIT, is temporary storage connected to a household-goods move. It is not automatically the same as renting a self-storage room. The mover may retain custody, price by shipment weight, charge warehouse handling, and schedule final delivery under its tariff and bill of lading.
| Washington Tariff 15-C example | Base Jan. 1, 2026 range | Current max after 3.35% supplement |
|---|---|---|
| Storage per 100 lb per 30 days | $0.98–$9.04 | About $9.34 maximum |
| Warehouse handling per 100 lb | $0.89–$13.87 | About $14.33 maximum |
| 7,000 lb: one 30-day storage period | Up to $632.80 | About $654.00 |
| 7,000 lb: one handling event | Up to $970.90 | About $1,003.10 |
| 7,000 lb: storage + two handling events | Up to $2,574.60 | About $2,660.20 |
The Washington Utilities and Transportation Commission's 2026 supplement permits a 3.35% increase to maximum tariff rates from May 1 through July 31, 2026. Calculations round display values; consult the tariff, supplement, mover's filed rates, and actual documents. Minimum rates do not necessarily change.

Storage-in-Transit Versus Self-Storage
With SIT, the shipment remains tied to the mover's transportation service and is commonly stored in a mover-controlled warehouse or vault. Customers may not have walk-in access. Charges may follow weight and tariff units rather than room dimensions. Final delivery can be another moving service, and responsibility is documented through the mover's bill of lading, inventory, warehouse records, and valuation terms.
Self-storage is usually a separate lease for a unit that the customer accesses and fills. It may have a lower monthly headline rate, but the household pays for unloading into the unit, loading out, trucks, labor, locks, protection, insurance, and possibly two extra move days. Compare complete door-to-door scenarios.
The SIT Cost Formula
Convert pounds to hundredweight by dividing by 100. Then calculate:
Handling = weight ÷ 100 × handling rate × billable events
Total = storage + handling + redelivery + valuation/access/other + applicable tax
If the shipment weighs 7,350 pounds, a tariff may bill the actual hundredweight, round it, or apply a minimum. If storage lasts 35 days, the tariff may prorate five days or charge two periods. The formula is simple; billing definitions are where expensive mistakes occur.
Current 2026 Tariff Example Explained
Washington's Household Goods Tariff 15-C became effective January 1, 2026. Its published storage range is $0.98 to $9.04 per 100 pounds per 30 days, and warehouse handling ranges from $0.89 to $13.87 per 100 pounds. A supplement permits a 3.35% increase to maximum rates from May 1 through July 31, producing rounded current maximum examples of $9.34 and $14.33.
This is valuable because it is an official, auditable schedule rather than an anonymous “average.” It is still limited: Washington intrastate rules do not set an interstate move's price, and an individual mover may charge below the maximum or apply other permitted items. After July 31, check for a new supplement before using the defaults.
Worked Storage-in-Transit Examples
4,000 pounds stored for one period
At $9.34 per hundredweight, storage is 40 × $9.34 = $373.60. If warehouse handling is charged twice at $14.33, handling is 40 × $14.33 × 2 = $1,146.40. Before redelivery and extras, the total is $1,520. A quote that advertises “storage under $400” can therefore omit most of the warehouse cycle.
10,000 pounds stored for three periods
Storage is 100 × $9.34 × 3 = $2,802. Two handling events add 100 × $14.33 × 2 = $2,866. Add a hypothetical $1,200 redelivery and $250 access charge, and the project reaches $7,118 before tax. Substitute actual rates and determine whether final delivery is already in the transportation estimate.
Closing delay of five days
Do not enter 0.17 periods until the contract confirms proration. A tariff could impose a minimum or different interval. Compare SIT with direct-delivery waiting, a delivery-date change, portable storage, or self-storage—but make sure every option includes labor and custody transfers.
Charges Commonly Missing From the Headline
- Warehouse handling in. Unloading, vaulting, inventory control, or placement may be a weight-based charge.
- Warehouse handling out. Pulling and loading for final delivery may create another event.
- Redelivery. Transportation and labor from warehouse to residence can be separate from original line-haul.
- Access services. Stairs, elevator, long carry, shuttle, parking, waiting, or difficult delivery can apply at the final address.
- Valuation or protection. Confirm how the selected protection operates during SIT, permanent storage, and transfers.
- Conversion fees. A shipment that exceeds the SIT limit may convert to permanent storage under new terms and responsibility.
How Long Can Goods Stay in SIT?
There is no safe universal answer. The Washington tariff example describes SIT up to 90 days before conversion to permanent storage, but other jurisdictions, interstate tariffs, military moves, and private contracts can use different limits or extension procedures. Your estimate and bill of lading should identify the controlling period.
Ask what notice is provided before conversion, whether an extension is possible, how rates change, who holds custody afterward, whether valuation changes, and how final delivery is ordered. Put a calendar reminder well before the deadline; an unplanned conversion can change both price and claims responsibility.
Inventory, Condition, and Access
Retain the mover's descriptive inventory and exceptions recorded at pickup. Photograph valuable or fragile items and the general shipment. Ask how vaults or containers are identified, whether upholstered goods are protected from floors, and whether the warehouse is appropriate for items sensitive to temperature or humidity. Standard storage does not necessarily mean climate controlled.
Ordinary customer access may be limited or unavailable because goods are vault-packed or stacked. If you will need work clothes, documents, medicine, school items, or tools, keep them out of SIT. If access is possible, ask about appointment, warehouse labor, minimum, retrieval, and rehandling charges.
Damage, Claims, and Valuation
For an interstate household-goods move, read FMCSA's valuation and claims materials and the mover's documents. Determine whether the same carrier retains custody in the warehouse or transfers goods to another entity. Record delivery exceptions promptly and follow written claim deadlines and evidence requirements.
“Insured storage” is not enough detail. Request the coverage basis, limits, deductible, exclusions, declared-value requirements, and responsibility during warehouse handling and redelivery. Homeowners or renters insurance may have off-premises sublimits or exclusions; ask the insurer rather than assuming.
How to Compare SIT Quotes
Give each mover the same estimated weight, origin, destination, expected dates, access facts, packing scope, valuation choice, and likely storage length. Normalize storage unit, handling events, minimum periods, proration, redelivery, access, and conversion. A lower per-hundredweight storage rate can lose after a higher handling rate.
Run three calculator cases: expected duration, one extra period, and conversion risk. If housing dates are uncertain, ask whether a portable container gives more schedule control or whether direct delivery can be held briefly. Choose the custody chain and service reliability you need, not just the lowest warehouse rent.
Frequently Asked Questions
How much does moving-company storage cost per month?
SIT is often weight-based. In the current Washington intrastate example, the maximum benchmark is about $9.34 per 100 pounds per 30 days through July 31, 2026. A 7,000-pound shipment is about $654 for storage alone.
What is warehouse handling on a moving estimate?
It is a charge associated with moving the shipment into or out of warehouse storage. It may apply more than once and can exceed one month of storage. Confirm the rate, weight basis, and number of events.
Is storage-in-transit cheaper than self-storage?
Not always. SIT can reduce coordination and preserve mover custody, while self-storage may have lower rent but adds unloading, reloading, trucks, labor, and another custody transition. Compare complete door-to-door totals.
Does SIT include final delivery?
Do not assume it does. Redelivery or final-mile transportation, crew labor, stairs, long carry, shuttle, and waiting may be separate. Ask for every post-storage charge in writing.
Can I access my belongings while they are in SIT?
Access may be limited or unavailable, especially when goods are vault-packed or stacked. If permitted, appointments, warehouse labor, minimums, retrieval, and rehandling charges may apply.
What happens when the SIT time limit expires?
The shipment may convert to permanent storage under different terms, rates, custody, and protection. Limits differ; the Washington example uses up to 90 days. Read the controlling tariff and contract and request any extension early.
Are interstate SIT rates the same as the Washington tariff example?
No. The example is an official Washington intrastate benchmark. Interstate prices and terms follow the applicable carrier tariff, estimate, bill of lading, and federal rules. Enter your actual rates in the calculator.
