Mail Musical Instruments Safely: USPS Tips

Last updated 12 hours ago. Our resources are updated regularly but please keep in mind that links, programs, policies, and contact information do change.

The United States Postal Service (USPS) excludes damage claims for instruments whose packing cannot withstand ordinary mail handling. Buying insurance does not remove the sender’s responsibility to make the instrument fit for the journey.

Shock or transportation damage is also excluded without evidence of damage to the mailing container. A broken instrument alone, then, does not settle whether USPS will reimburse its owner.

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. That extra layer of cushioning belongs in the measurement even when it makes a faster service unavailable.

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 itself does not qualify for Media Mail, whose eligible items include printed music and sound recordings but not instruments.

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

Larrivée’s shipping instructions call for paper beneath and above the headstock, enough support to hold it slightly above the neck rest, without overdoing the compression when the lid closes. Larrivée then instructs the sender to place the case in a carton with inserts and fill the spaces around it with crumpled paper. Check stability at both levels: stopping the guitar inside its case does not finish the job if the case can move inside the box.

Larrivée tells owners to maintain string tension in standard tuning. StewMac’s guitar-shipping guide acknowledges the disagreement and recommends slightly loosening strings rather than leaving them completely slack. There is no useful universal instruction to detune every guitar; follow the instrument maker’s directions or ask the receiving repairer before changing its setup. Extra padding is also no excuse to force a case shut against the instrument.

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 transfer a violin’s packing instructions mechanically to a cello, or improvise a change to an unfamiliar bridge or setup. For an instrument whose adjustment is beyond your experience, get the receiving shop’s instructions before beginning to dismantle anything.

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. A closed accessory compartment should be assessed for what it holds, not treated as permission to leave metal parts loose.

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. Count the small parts as part of the shipment, so unpacking does not leave the recipient searching through discarded cushioning.

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. Obsolete markings on a reused mailing container must be obliterated. USPS-produced packaging must be used for the matching postal product even if its markings are removed or the container is reconfigured. A reused commercial carton and a reused Priority Mail box have different postage consequences; covering a service name does not turn postal packaging into an ordinary box.

Put the recipient’s name and destination address inside the box, and place the exterior return address, delivery address and postage on the same side, parallel to its longest side. USPS says not to bend, fold or overlap the exterior labels. Prepare the backup address before closing the box, when it is still easy to add.

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. For a performance or repair appointment, compare the actual service commitment for the destination with the date the instrument must be available. 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 battery-equipped instrument or a shipment to Alaska, Hawaii or a territory 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, while Ground Advantage applies dimensional-weight pricing to packages larger than 1 cubic foot when that calculated weight exceeds the actual weight. For that Ground Advantage calculation, measure length, width and height in inches, round each fractional inch upward, multiply the three measurements, and divide by 139 to obtain the dimensional 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. Use that finished-package quote 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. A large rectangular instrument carton does not become a Flat Rate shipment simply because its weight is below that limit.

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. For a family instrument, separate what a lost object would mean personally from the amount that mailing insurance can reimburse. 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. Upon a written USPS request, the claimant must present the retained damage evidence at a local Post Office for inspection. Photographing the damage does not replace keeping the box, cushioning and contents available for that inspection. Resist the understandable urge to discard the mess or send the surviving parts onward while the claim is pending.

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. Match any additional valuation or packing evidence to the stated reason for denial, so the appeal answers the issue USPS actually decided.

Check batteries and destination rules before mailing overseas

Used, damaged or defective electronic devices containing or packaged with lithium batteries cannot travel by domestic air transport, with exceptions for devices new in original packaging and manufacturer-certified new or refurbished devices. The domestic address side for used devices must bear the markings “Restricted Electronic Device” and “Surface Transportation Only.” For a rechargeable keyboard or electronic instrument, establish the battery type and device condition before selecting a service. A surface-only parcel cannot be made eligible for air transportation simply by buying faster postage.

Qualifying lithium batteries must be installed in the equipment they operate for international or military and diplomatic mail. 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. Do not assume that a battery parcel accepted domestically can also be sent abroad.

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. Check the destination’s rules before finalizing the box or sale, rather than discovering a restriction at the counter.

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. Recalculate the coverage decision for an overseas shipment instead of carrying over the domestic limit.

Before surrendering an instrument, decide whether its packing, route and recoverable value are acceptable together. If one of those answers is uncertain, settle it while the instrument is still in your hands.
