Direct answer
For international USPS mailing, the rule is conditional rather than universal. The destination country must not prohibit cremated remains, and USPS specifies Priority Mail Express International where that service is available. The current destination-country listing must be checked for mailing conditions, postage prices, and extra services.
International preparation also has stated conditions. USPS requires a sealed siftproof funeral urn inside a strong, durable outer container with sufficient cushioning; the outer container must also be siftproof. The contents must be identified on the applicable customs declaration.
These facts do not establish that mailing is permitted on every route, that a particular country currently accepts cremated remains, or that a specific package will be accepted. They also do not answer a domestic interstate mailing question. The international rules and any domestic route are separate questions.
Evidence boundaries
The USPS provisions addressed here are international provisions. They cover destination-country restrictions, the specified international mail service, packaging, contents identification, country listings, and customs-form preparation. They do not provide a general rule for domestic interstate travel or domestic mailing.
CDC guidance concerns importing human remains into the United States. It states that federal requirements depend on the purpose of importation, whether the remains were embalmed or cremated, and whether the death involved an infectious disease. That is a separate official-source branch and should not be collapsed into domestic interstate travel.
EPA and the federal regulation describe a different activity: transportation and burial at sea of cremated human remains in ocean waters under specified conditions. That material does not establish permission for a specific voyage, vessel, aircraft, operator, state water, inland water, beach, park, or private property.
Comparison table
The distinctions below preserve the scope of each official source. A branch is not evidence for a different route or activity.
What remains unknown
No dated price record is provided for mailing cremated human remains. The USPS material identifies country-specific postage prices as information in the Individual Country Listings, but no destination, service availability result, or price is provided here. The cost therefore remains unresolved.
The evidence does not identify whether a particular destination country currently prohibits or accepts cremated remains. It also does not establish that a particular USPS Cremated Remains kit satisfies every international packaging condition. The country listing and the actual packaging requirements remain to be checked for the specific shipment.
The evidence does not answer whether keeping human ashes at home is unlawful. It contains no nationwide domestic rule on that question, and the international mailing, importation, and ocean-burial branches should not be used to create one.
Practical follow-up questions
For an international shipment, identify the destination country and check its current USPS Individual Country Listing. That listing supplies the destination-specific mailing conditions, postage prices, and extra services used for the next check.
Confirm whether Priority Mail Express International is available for that destination. USPS identifies that service for international mailing of cremated remains, but availability must be confirmed for the particular destination.
Check the package against the stated conditions: whether the funeral urn is sealed and siftproof, whether the outer container is strong and durable, whether it is siftproof, and whether sufficient cushioning is present. A particular kit should not be treated as automatically satisfying every condition.
Confirm the applicable customs declaration and preparation route in the current USPS customs-form table. USPS identifies PS Form 2976-B for Priority Mail Express International items and states that customs forms must be electronically generated; the current table remains the place to confirm the requirement.
Questions people ask
How much does it cost to mail cremated human remains? No exact cost is established here. USPS states that Individual Country Listings contain destination-specific postage prices and extra services, while no destination or current price is identified.
Is it illegal to keep human ashes at home? That question remains unresolved here. The cited material addresses international mailing, importing human remains, and burial at sea; it does not establish a nationwide rule about keeping ashes at home.
Which verified facts apply to this question? For international mailing, the relevant facts concern a destination-country prohibition check, Priority Mail Express International where available, siftproof packaging, contents identification, country-specific conditions, and customs-form confirmation. Importation and ocean burial are separate branches.
What remains unknown until current documents are checked? The destination's current acceptance or prohibition, service availability, postage price, applicable country conditions, and the current customs-form preparation route remain unresolved until the relevant USPS documents are checked.
Evidence behind this page
Each point below is restricted to what the cited primary source supports. Administrative listing status is not a quality endorsement.
| Evidence | Supported point | Scope and limitation |
|---|---|---|
| Evidence 1 | Point to the current USPS customs-form table as the place to confirm the form and preparation route for international cremated-remains shipping. | Do not prepare a form for the reader, treat a printed example as current instructions, or assume another mail class has the same form requirement. |
| Evidence 2 | Direct readers to the current USPS Individual Country Listing to check mailing conditions and service availability before shipping cremated remains internationally. | Do not reproduce a country rule without separately verifying that country's current listing or infer acceptance from the generic section. |
| Evidence 3 | Tell readers that international USPS shipping of cremated remains requires truthful contents identification on the applicable customs declaration. | Do not fill in a customs declaration, prescribe a classification, or guarantee customs acceptance or delivery. |
| Evidence 4 | Use the current USPS international packaging conditions as a packing checklist for cremated remains. | Do not certify a reader's package, suggest a particular kit automatically satisfies every condition, or omit destination-specific checks. |
| Evidence 5 | Name the USPS service specified for international cremated-remains shipping and instruct readers to confirm its availability for their destination. | Do not substitute another mail class, promise service to a country, estimate transit time, or quote an unverified price. |
| Evidence 6 | Explain that USPS international shipping of cremated remains starts with a destination-country prohibition check, and link the current country listing. | Do not claim every country accepts cremated remains, decide a destination's current rules, or replace the country listing or local authority. |
| Evidence 7 | Explain the federal ocean-water branch with the current EPA page and regulation together. | Do not convert the general permit into permission for a specific voyage, vessel, aircraft, operator, state water, inland water, beach, park, private property, or non-human remains. |
| Evidence 8 | Identify international importation as a separate official-source branch that must not be collapsed into domestic interstate travel. | Do not apply CDC import steps to a domestic trip, predict admissibility, supply a permit result, or replace consular, carrier, public-health, customs, or destination instructions. |

That remains unresolved here. The cited material addresses international mailing, importing human remains, and burial at sea, not a nationwide rule about keeping ashes at home.
Which verified facts apply to this question?
For international mailing, the relevant facts address destination-country restrictions, Priority Mail Express International where available, siftproof packaging, contents identification, country-specific conditions, and customs-form confirmation. Importation and ocean burial are separate branches.
What remains unknown until current documents are checked?
The destination's current acceptance or prohibition, service availability, postage price, applicable country conditions, and customs-form preparation route remain unresolved until the relevant USPS documents are checked.
