Short answer: For a U.S. evidence relocation, choose the provider that can show, in writing, how each item will be identified, sealed, handed over, transported, stored, and delivered. A high review score, a "secure" marketing label, or real-time GPS tracking doesn't prove that the provider meets your agency, laboratory, or court requirements.

The evidence custodian's policy, laboratory instructions, contract, and applicable transportation rules control. This is practical information for police departments, law offices, laboratories, and other organizations arranging a physical evidence move. It isn't legal advice.

What controls the selection

Chain of custody is the traceable record of who controlled, transferred, stored, or analyzed evidence. The NCBI overview of chain of custody describes that traceability as critical to forensic practice.

A mover can document its part of the chain, but it can't repair an earlier gap, decide whether evidence is admissible, or replace the authority of the evidence custodian. Before requesting quotes, require a process that records:

A standard inventory list is useful, but it isn't a custody log. A GPS report can show where a vehicle went, but it doesn't identify who had access to a package or whether its seal remained intact.

No single certification or label, by itself, establishes that a company can handle every type of evidence. The material, route, facility, and agency procedures determine what the mover must do.

Before you ask for a quote

Prepare a written scope so each company prices the same work. Include:

Don't give a mover authority to improvise preservation steps. The provider should work from the custodian's instructions and identify anything it can't safely or lawfully handle.

For digital devices, put restrictions in writing. Specify whether the mover may access, connect, power on, charge, or otherwise handle a device. Apply the same approach to firearms, controlled substances, chemicals, and other high-risk items: have the custodian identify the applicable agency procedures before pickup.

Verify the provider and contracting entity

Ask for the company's:

The entity named on the quote should be the entity responsible under the contract. Don't assume that a familiar van-line or brand name is the same as the company that will physically handle the evidence.

General U.S. moving-company screening advice recommends checking identity, registration or licensing, insurance, complaint history, and operational details. Moving Scam Stories' verification checklist and MoveBuddha's background-check guide are possible starting points for general screening, but neither is an evidence-handling standard.

Request references for work that involved comparable custody, security, or environmental controls. A review score may indicate customer satisfaction; it doesn't establish secure custody, dangerous-goods training, or suitable insurance.

Require a written custody and security plan

A credible quote should explain how the provider will manage the following controls:

Control What to request
Access The names or roles of personnel allowed to handle the shipment and how each access event is recorded
Seals and inventory Unique package IDs, seal numbers, pickup photographs, and a count at delivery
Handoffs A signed, time-stamped record for every transfer, including temporary storage
Vehicle and route Vehicle security, monitoring, loading restrictions, and the response to an unscheduled stop or delay
Storage Access logs, an alarmed or restricted space, environmental controls, and the maximum storage time
Special materials Classification, approved packaging, labels, and proof of required training
Subcontractors Names, responsibilities, approval process, and a record of every additional handoff
Exceptions Immediate notification, photographs, an incident report, and preservation of relevant logs
Records File format, retention period, authorized corrections, and delivery of the final custody file

Ask to see a redacted sample custody form and exception report before signing. The forms should show package IDs, seal numbers, people, dates, times, locations, and signatures or other approved authentication for each transfer.

The contract should also state what happens if a tracker fails, the route changes, a seal is damaged, a vehicle is delayed, or delivery is offered to someone other than the planned recipient. "Real-time tracking" is a feature, not a complete chain-of-custody system.

Rules for biological or potentially infectious evidence

Biological evidence may trigger hazardous-material rules if it meets the definition of an infectious substance. The Washington State Department of Health shipping guidance identifies the U.S. Department of Transportation Hazardous Materials Regulations in 49 CFR Parts 171-180 and says packaging and shipping should be performed or supervised by a person trained for Division 6.2 materials.

The University of Illinois biological-material guidance distinguishes categories such as:

For example, Category B packages generally require the UN3373 marking and the words "Biological Substance, Category B." Category A shipments use different packaging and labeling requirements, including IATA Packing Instruction 620.

The NIH-supported review of biospecimen shipping describes triple packaging and requirements concerning pressure, temperature, and package strength. Those requirements don't automatically apply to every biological item in an evidence room. Ask the evidence custodian or a qualified laboratory safety professional to classify the material before the mover quotes, packs, or transports it.

For regulated biological material:

Don't ask an ordinary mover to open, dry, repackage, classify, or dispose of biological evidence without written authorization and properly trained personnel. If dry ice or another cooling method is used, the package must account for gas and pressure. The Washington guidance warns that trapped carbon dioxide in an airtight container can create high pressure and an explosive hazard.

For material that isn't regulated as an infectious substance, follow the agency or laboratory's preservation instructions rather than applying shipping labels automatically. A suitable provider will ask for those instructions instead of promising that its ordinary packing method works for every item.

Plan each stage of the move

Agree on the procedure before pickup:

  1. Release: The custodian verifies the inventory, seals, condition, and authorized recipient.
  2. Packing: The mover uses approved containers and doesn't combine items in a way that defeats individual identification or required segregation.
  3. Loading: The parties record package counts, seal numbers, vehicle details, and the person taking custody.
  4. Transit: The provider records custody, route exceptions, delays, environmental readings, and any temporary storage.
  5. Delivery: The recipient verifies identity, count, seals, and condition before signing.
  6. Closeout: The provider delivers the signed custody log, photographs, exception report, temperature records, and invoice.

A delivery signature alone isn't enough if the shipment passed through several handlers. Each handoff, including a transfer into or out of temporary storage, should appear in the record.

Don't rely on household-goods valuation

A household mover's standard valuation may not protect high-value evidence. The Surface Transportation Board's lost-or-damaged-items guidance concerns household-goods moves. It describes a $0.60-per-pound liability level and a valuation statement, including a declaration for articles worth more than $100 per pound.

Under that example, a 20-pound item could have only $12 of weight-based coverage even if its actual value were much higher. This isn't a universal evidence-transport standard, but it shows why an evidence-relocation contract must state valuation, exclusions, and claims procedures clearly.

Ask for the certificate of insurance and written exclusions. Check coverage while items are being packed, loaded, transported, stored, handled by subcontractors, exposed to temperature changes, or affected by contamination or a broken seal.

The contract should state:

Don't assume that a $1 million per-item limit is universally required or automatically available. Insurance may compensate a covered loss, but it can't restore an evidentiary record or eliminate the need to report a custody incident.

Compare itemized quotes

There is no dependable single price for a secure evidence move. The quote may depend on:

Request at least two comparable, itemized quotes. Ask whether each price includes packing, custody records, secure storage, monitoring, incident reporting, and insurance. A low per-pound or per-mile rate may exclude the controls that make the move suitable for evidence.

Don't approve a quote that leaves hazmat handling, storage, security, waiting time, or incident reporting as undefined add-ons. Have the custodian compare the proposed process, not just the total price.

Red flags in a quote

Pause the selection process if a company:

A specialized provider isn't automatically the right provider. The written process, the assigned staff, and the contract controls matter more than the label.

If evidence is lost, damaged, or delivered with a broken seal

Treat a discrepancy as a custody incident, not merely a damaged-box claim.

  1. If there is a spill or suspected biological hazard, keep people away and contact trained safety or emergency personnel.
  2. Notify the evidence custodian and the provider immediately under the agreed incident plan.
  3. Don't open, clean, dry, reconnect, or repackage the item unless the responsible protocol authorizes it.
  4. Photograph the package, seal, labels, vehicle area, and visible damage when safe.
  5. Record who discovered the issue, when it was discovered, and who was present.
  6. Preserve GPS data, temperature logs, photographs, messages, bills of lading, and custody records.
  7. Request a written incident report and a complete handoff history.
  8. Follow the agency, laboratory, contract, and claims procedures.

A household-goods contract may have a different dispute process from an evidence-relocation contract. The STB notes that a denied household-goods claim may require arbitration or a lawsuit to obtain compensation.

Have the appropriate agency official or qualified counsel decide what the incident means for the investigation or proceeding. Don't let the mover close the matter with an informal replacement or credit.

Questions to send with a quote request

Ask each company to answer these questions in writing:

Choose a provider only after its written answers match the evidence custodian's requirements. Before pickup, attach the approved scope, custody form, handling instructions, insurance terms, and incident contacts to the contract.
