Shipping electronics requires extra care, especially when batteries are involved. From packaging guidelines to USPS requirements, many factors ensure your device travels safely and complies with postal regulations.
Why Special Care Matters
When sending electronic devices through the mail, two major concerns exist:
- Damage or Breakage
Delicate internal components can be damaged if not properly cushioned. - Battery Hazards
Batteries—especially lithium-ion—pose fire or explosion risks if mishandled during transit.
Following USPS rules protects your device and ensures you comply with federal and international regulations governing hazardous goods shipments.
USPS Battery Rules
USPS follows federal hazardous materials regulations for transporting batteries. Key requirements include:
- Lithium-ion batteries must be shipped to prevent short circuits, damage, or accidental device activation.
- Batteries must be securely packed—usually inside the device or separately, with protected terminals (taped or capped).
- Batteries showing damage or leakage cannot be shipped.
- Some battery shipments require specific hazardous material labeling if sent separately (not installed in equipment).
For compliance, ensure the battery is either installed in the equipment or individually protected against contact with metallic objects.
For the latest guidelines, refer to USPS Publication 52 (Hazardous, Restricted, and Perishable Mail).
Battery Types and Regulations
Lithium-ion (Rechargeable)
- Found in smartphones, laptops, tablets, and most portable devices
- Must be no more than 100 Wh (watt-hours) for standard shipping
Lithium Metal (Non-Rechargeable)
- Common in cameras, watches, and small medical devices
- Must contain 2 grams or less of lithium per battery
Alkaline or Non-Spillable Batteries
- Less restrictive, but must be secured to avoid short circuit or leakage
Damaged Batteries
- Generally not mailable under USPS rules due to safety concerns
Packaging Electronics Properly
Power Off and Disconnect
Turn off the device completely to prevent heating up during transit. Remove all accessories, chargers, cables, or removable storage to avoid stress on ports.
Handle Batteries Correctly
For removable batteries, wrap them in non-conductive material (such as a plastic bag) and tape the terminals to prevent contact.
For non-removable batteries, ensure the device is powered off and cannot accidentally turn on. Consider using protective wraps around switches or power buttons.
Wrap the Device
Use bubble wrap or foam to wrap the device in at least 2–3 layers of protective material. Add corner and screen protectors for tablets, phones, or laptops.
Add Cushioning
Choose a sturdy corrugated cardboard box with enough room for 2–3 inches of padding on all sides. Fill empty spaces with bubble wrap, air pillows, packing peanuts, or crumpled paper to prevent shifting.
Seal and Label
Use strong packing tape to reinforce all seams. If shipping lithium batteries separately, affix appropriate hazmat or battery markings according to USPS guidelines.
USPS Shipping Options
Priority Mail
- 1–3 day delivery in most cases
- Includes tracking and up to $100 insurance (retail rate)
- Good balance of speed and cost for most electronics
Priority Mail Express
- Overnight or 2-day guaranteed service to most U.S. locations
- Includes tracking and up to $100 insurance
- Ideal for urgent or higher-value devices
USPS Retail Ground
- More economical but slower than Priority services
- Best for less time-sensitive shipments or heavier parcels
First-Class Package Service
- For small electronic devices under 1 lb (15.999 ounces max)
- Cheaper but slightly slower than Priority Mail
Domestic vs. International Shipping
Domestic Shipments
Domestic shipping within the U.S. has fewer restrictions on lithium batteries installed in equipment. However, standalone lithium batteries have more stringent packaging and labeling requirements.
International Shipments
International shipments face stricter rules—some countries prohibit lithium battery shipments entirely or allow them only when installed in devices.
Always check the destination country’s regulations and review the USPS International Mail Manual for up-to-date information. Many carriers limit or prohibit international shipments of standalone batteries.
Insurance and Extra Services
When shipping valuable electronics, consider these additional services:
Additional Insurance
If your device exceeds the default coverage value, purchase extra insurance from USPS. Learn more about USPS insurance options.
Signature Confirmation
This service ensures the package isn’t left unattended, as the recipient must sign upon delivery.
Registered Mail
This is the most secure USPS service, though slower. It works well for extremely valuable devices or sensitive items.
Common Mistakes to Avoid
Ignoring Battery Restrictions
Improper labeling or packaging can cause delays, returned packages, or fines.
Using Inadequate Packaging
Electronics need robust cushioning. Flimsy boxes dramatically increase damage risk.
Shipping Damaged Batteries
USPS prohibits mailing defective, recalled, or leaking batteries.
Missing Address Verification
Always double-check the destination address to prevent misdelivery or rerouting.
FAQs
Can I ship a phone with a lithium battery inside?
Yes, if the battery is installed in the phone. Wrap the phone securely and follow USPS packaging rules. No additional labeling is required if the battery is installed and within USPS limits.
Do I need a special label for shipping my laptop?
If your laptop battery is installed and under the allowable watt-hour limit, you typically don’t need a special hazardous label for domestic shipping. International destinations may require additional labeling.
Is it safer to remove a device’s battery before shipping?
If the battery is easily removable, removing and wrapping it separately can reduce the risk of damage or accidental activation. Follow USPS guidelines for packaging separated lithium batteries.
How do I check if my lithium battery exceeds 100 watt-hours?
Check your device’s user manual or the battery label for watt-hour (Wh) information. Many manufacturers also list this information on their websites.
Can I ship power banks or portable chargers?
Yes, but power banks are considered standalone lithium batteries. You must follow USPS rules for single-piece battery shipments, including correct labeling, secure packaging, and potential restrictions on service type or destination.
