Mail Musical Instruments Safely: USPS Tips

Last updated 2 weeks ago. Our resources are updated regularly but please keep in mind that links, programs, policies, and contact information do change.

Whether a musical instrument can go by mail depends first on the packed box. The United States Postal Service (USPS) accepts Ground Advantage packages of up to 70 pounds, within size limits that differ by service. Eligible Ground Advantage and Priority Mail shipments include $100 of insurance, and coverage of up to $5,000 can be purchased.

Insurance does not replace sound packing. USPS excludes damage claims for instruments whose packing cannot withstand ordinary mail handling. It also excludes shock or transportation damage unless the mailing container itself shows damage.

Start with the packed instrument, not the postage

USPS Ground Advantage accepts packages weighing up to 70 pounds, with a maximum of 130 inches in combined length and girth. Priority Mail has a maximum combined length and girth of 108 inches. USPS measures length along the longest side and girth around the package perpendicular to that side. Measure the finished outer box, rather than the bare instrument or its carrying case.

For a cello, a long keyboard or several drums, establish whether the protected parcel fits before promising a buyer any particular shipping service. Do not solve an oversized parcel by stripping away the protection that keeps the instrument stable.

An instrument does not qualify for Media Mail, which is limited to listed items such as printed music and sound recordings.

Make the case and box work together

USPS requires cushioning to protect multiple contents from one another as well as from outside forces, with particular care separating heavy items from fragile ones. A loose mouthpiece, power supply or piece of drum hardware deserves its own secure place rather than room to travel beside the instrument. Use strong outer packaging with enough room for cushioning that protects the instrument and prevents shifting. Work from the inside out: settle the instrument and accessories first, then stabilize the case inside the shipping carton.

Guitars: support the neck and follow the maker’s setup advice

Guitar maker Larrivée’s shipping instructions call for crumpled paper beneath and on top of the headstock, enough to hold it slightly above the neck rest. Larrivée says not to overdo it, though some compression should be felt when the case lid closes. Larrivée then instructs the sender to place the case in a cardboard carton from a guitar shop, with its two inserts, and fill the spaces around it with crumpled paper.

Larrivée tells owners to maintain string tension in standard tuning. StewMac’s guitar-shipping guide says experts disagree about string tension and recommends a middle ground: loosening the strings slightly without letting them go completely slack. No single rule on string tension fits every guitar; follow the maker’s directions, or ask the repair shop that will receive it, before changing the setup.

Violins and cellos: distinguish shipping preparation from repair work

Stamell Stringed Instruments advises slightly loosening violin strings while retaining some tension on the bridge, wrapping the tailpiece and padding both sides of the bridge. It also calls for padding that prevents movement inside the case, a secured bow with loosened hair, and cushioning between the case and the shipping box. Stamell asks customers to call for information about shipping cellos and bows. Do not apply a violin’s packing instructions mechanically to a cello. Preparing an instrument for shipping is not repair work: if an adjustment is beyond your experience, get the receiving shop’s instructions before taking anything apart.

Brass, keyboards and drums: secure the parts as well as the instrument

Heritage Trumpets recommends enough cushioning inside a trumpet case to keep the horn stable without forcing the case shut. It says to wrap loose items such as mouthpieces separately and secure them inside the case or ship them separately.

Bell Tone Synth Works requires keyboard synthesizers shipped to its shop to arrive in a road case or hardshell case, without crumbling foam inside. Confirm the receiving shop’s requirements before buying a keyboard box, and inspect the existing case padding before trusting it.

Sound Pure’s drum-packing guide recommends removing and separately wrapping loose hardware, bagging screws and claws together, and removing and securing the hoops. Its suggested spacing is at least 2 inches between the outside of the drum shells and the inside of the outermost box.

Close and address the finished box

USPS says to secure all seams with sufficient 2-inch-wide packing tape and avoid wrapping a parcel in string, cord or twine. Any outdated marking on a reused box must be covered or removed completely. USPS-produced packaging, such as a Priority Mail box, may be used only for the product it was made for, and the sender must pay that product’s price however the box is reconfigured or its markings are covered.

Put a slip of paper with the recipient’s name and destination address inside the box. On the outside, write the address parallel to the longest side, with the return address, delivery address and postage on the same side. USPS says not to bend, fold or overlap the exterior labels.

Choose speed after measuring the package

USPS lists ordinary Ground Advantage delivery as 2 to 5 business days, without a guarantee. Priority Mail’s expected delivery is generally 2 to 3 days depending on origin, destination and drop-off time, without a money-back guarantee. Priority Mail Express advertises 1 to 3 day delivery by 6 p.m. with a money-back guarantee, subject to limited exceptions, to most United States addresses and post office boxes. An expected delivery date is a planning estimate; leave room in the schedule if missing it would create a serious problem.

Ground Advantage’s published window rises to 2 to 8 business days for hazardous-material shipments within the contiguous states, and 10 or more business days between those states and the listed noncontiguous locations. A shipment to Alaska, Hawaii or a territory, or an instrument whose battery makes it a hazardous-material shipment (see the battery rules below), needs a route-specific check rather than an assumption based on the ordinary window.

Priority Mail postage in a sender’s own box depends on weight and distance. Priority Mail also uses dimensional-weight pricing for packages larger than 1 cubic foot when the calculated dimensional weight exceeds the actual weight. Ground Advantage charges by dimensional weight, a figure calculated from the box’s measurements, for a package larger than 1 cubic foot when that figure exceeds the actual weight. To find the dimensional weight, measure length, width and height in inches, round each fractional inch upward, multiply the three measurements, and divide by 139 to get a weight in pounds. A light guitar in a roomy carton can therefore be priced for its bulk rather than its weight on the scale.

Ground Advantage also lists extra fees for parcels 22 to 30 inches long, longer than 30 inches, larger than 2 cubic feet, or having a nonstandard shape or material. USPS directs customers to its Price Calculator with the package’s weight, shape and size measurements. Get that quote for the finished package on each service under consideration, instead of budgeting from the instrument’s weight alone. Only USPS-produced Flat Rate boxes and envelopes qualify for domestic Flat Rate prices, with a maximum weight of 70 pounds.

Buy coverage that fits the instrument’s value

USPS lists $100 of standard included insurance for eligible Ground Advantage, Priority Mail and Priority Mail Express shipments. Additional domestic insurance can be purchased up to $5,000, with fees based on declared value and limitations for some products and items. USPS depreciates used articles according to their life expectancy when assessing loss or damage. Compare coverage with a defensible value for the specific instrument, not just the cost of buying a new one.

The domestic claims rules exclude claims based solely on sentimental value and losses beyond the value of the instrument itself. If the instrument is worth more than the available coverage, resolve that gap before entrusting it to the mail.

USPS excludes damage claims involving packaging that could not survive the normal course of the mail, and articles whose fragile nature prevented safe carriage regardless of packaging. It also excludes damage caused by shock, the transportation environment or X-ray without evidence of damage to the mailing container. Those exclusions make packing and the condition of the outer box relevant to a claim, even when the instrument itself is unquestionably damaged.

Acceptable proof of value includes a sales receipt, paid bill of sale, a reputable dealer’s value statement or repair estimate, and records of a completed online sale. Evidence of insurance can include the original mailing receipt or a printed electronic label record, and the tracking number appears on the label or mailing record. Gather the valuation record before mailing a used instrument whose price may be difficult to establish afterward. Share the mailing records with the recipient so either person can assemble the claim if delivery goes wrong.

Keep the evidence for a damage or loss claim

Either the sender or recipient may file an insured domestic claim, with the original mailing receipt and proof of insurance, value and damage. If the parcel arrives damaged, USPS says to retain all contents and original packaging until the claim is settled, including undamaged items, and may require inspection of the entire package.

A damage claim also needs an estimate of repair costs from a reputable dealer; photographs showing the extent of damage help support the claim. If USPS asks in writing, the claimant must bring the proof of damage to a local Post Office in person for inspection. Photographing the damage does not replace keeping the box, cushioning and contents available for that inspection.

For damaged items or missing contents, a claim may be filed immediately but no later than 60 days after mailing. Count from the mailing date rather than the day the damage was discovered.

Distinguish a lost parcel from missing contents inside a delivered parcel, because the earliest filing dates differ.

USPS prefers online domestic claims, with uploaded proof of value; insurance evidence must be retained until the claim is resolved. A denied or partially paid claim can be appealed within 30 days of receiving the decision, using the same method as the original claim and addressing the reasons for denial. If that appeal is denied, a second appeal is available within 30 days of receiving the appeal denial.

Check batteries and destination rules before mailing overseas

For a rechargeable keyboard or electronic instrument, establish the battery type and device condition before selecting a service, including for a shipment within the United States. Used, damaged or defective electronic devices that contain or are packed with lithium batteries cannot travel by air in domestic mail. The rule does not apply to devices that are new in original packaging or that the manufacturer has certified as new or refurbished. A used, damaged or defective device must be marked “Restricted Electronic Device” and “Surface Transportation Only” on the address side of the package. A surface-only parcel cannot be made eligible for air transportation simply by buying faster postage.

In international mail and military or diplomatic mail, USPS allows qualifying lithium batteries that are properly installed in the equipment they operate. Used, damaged, defective or recalled lithium batteries are prohibited internationally and to, from or between military and diplomatic mail locations. Used, damaged or defective devices containing or packaged with lithium batteries are also prohibited on those routes, with the same exceptions for new and manufacturer-certified devices.

For an international shipment, USPS directs customers to the destination’s Individual Country Listing for prohibited contents and weight and size limits. A handwritten customs form must be taken to a USPS retail associate to create the computer-generated form, and mistakes can cause delays, extra import fees or rejection.

Priority Mail International merchandise shipments include up to $200 of insurance at no extra charge. Priority Mail Express International includes up to $200 of merchandise insurance, with additional coverage subject to country prohibitions and restrictions.
