NAGPRA Explained: What Private Collectors of Native American Material Need to Know
The Native American Graves Protection and Repatriation Act, passed in 1990 and usually called NAGPRA, is best known for requiring museums and federal agencies to return certain items to tribes. Private collectors sometimes assume it doesn't touch them. That's a mistake. NAGPRA includes a federal trafficking provision, and it sits alongside other federal and state laws that apply directly to private buying and selling.
This guide explains NAGPRA in general terms, how it interacts with other laws, and what an ethical collector should do. It is not legal advice. If you hold material that may be covered, talk to a lawyer and to the tribes concerned.
What NAGPRA covers
NAGPRA defines several categories of "cultural items." In plain language:
| Category | General meaning | Collector takeaway |
|---|---|---|
| Human remains | The physical remains of a Native American person | Never buy, sell, trade or display. Full stop. |
| Funerary objects | Objects placed with individual human remains at the time of death or later as part of a death rite or ceremony | Avoid. "Grave goods" and "burial" listings are a red line. |
| Sacred objects | Specific ceremonial objects needed by traditional Native American religious leaders for the practice of traditional religions by present-day adherents | Avoid unless lawful history is clear; consult the relevant tribe. |
| Objects of cultural patrimony | Objects with ongoing historical, traditional or cultural importance to a group as a whole, which no individual had the right to sell or give away | Can't be lawfully alienated by an individual. Avoid. |
These definitions are legal terms with detailed meanings in the statute and regulations. Whether a particular object falls into a category is often a question for tribes and experts, not for a seller's description.
The parts of NAGPRA that apply to institutions
Most of NAGPRA's machinery applies to museums and federal agencies. Institutions that receive federal funding must inventory and summarize covered collections, consult with tribes and Native Hawaiian organizations, and repatriate items to lineal descendants or affiliated tribes on request. The regulations implementing NAGPRA were substantially revised in recent years to strengthen tribal consultation and consent, and museums across the country have changed how they display and store Native American material as a result.
NAGPRA also sets rules for new discoveries on federal and tribal land: intentional excavation requires a permit and consultation, and inadvertent discoveries must be reported and the activity stopped.
The trafficking provision: where private collectors come in
NAGPRA amended the federal criminal code to add a trafficking offense. In general terms:
- Selling, purchasing, using for profit, or transporting for sale Native American human remains without the right of possession is a federal crime.
- Selling, purchasing, using for profit, or transporting for sale Native American cultural items obtained in violation of NAGPRA is also a federal crime.
Penalties include fines and imprisonment, with heavier penalties for repeat offenses. Federal prosecutors have also combined NAGPRA trafficking charges with ARPA charges where items came from public or tribal land.
There is no collecting category, no age and no "old collection" story that makes trading in Native American human remains acceptable. That includes bones, teeth, hair, and objects made from human remains. Many states also prohibit sale of any human remains. If you discover remains in an estate, do not sell or discard them. Contact a lawyer, your state archaeologist or SHPO, and the National NAGPRA program for guidance on appropriate steps.
Other laws that work alongside NAGPRA
- ARPA covers removing archaeological resources from federal and tribal land, and buying or selling them.
- State unmarked burial laws protect graves on private and state land in most states.
- The Safeguard Tribal Objects of Patrimony (STOP) Act, enacted in 2022, prohibits exporting Native American cultural items obtained in violation of law, increases penalties, and sets up a voluntary return process. If you're considering selling abroad or buying from overseas auctions, this matters.
- Wildlife laws such as the Bald and Golden Eagle Protection Act and the Migratory Bird Treaty Act restrict possession and sale of feathers and parts from protected birds, which are common on ceremonial objects.
- Indian Arts and Crafts Act: for modern work, it is illegal to market goods in a way that falsely suggests they are Native American made.
How an ethical collector handles Native American material
When buying
- Skip any listing that mentions burials, graves, mounds, caves with burials, "funerary," or human remains.
- Be cautious with anything described as ceremonial, sacred, a medicine bundle, a mask used in ceremony, or a community object. Ask questions, and consider asking the tribe.
- For stone tools and pottery, ask for find location, land status and landowner permission records.
- Avoid objects with feathers or animal parts unless you've confirmed they comply with wildlife law.
- Check that the seller is willing to answer questions in writing. Evasion is a signal.
When you already own something
- Document what you have. Photographs, measurements, any labels, and everything you know about where it came from.
- Separate anything that may be human remains or funerary material and stop all handling beyond what's needed to store it respectfully.
- Get advice. A lawyer familiar with cultural property, your SHPO, and the National NAGPRA program can help you understand options.
- Consider contacting the tribe. Many tribes have historic preservation officers who welcome contact from private holders. Voluntary return is common and often the right thing to do.
- Don't sell on a guess. Selling a covered item can create criminal exposure and can harm the communities connected to it.
Marketplaces and auction houses
Most major online marketplaces prohibit listing human remains and restrict Native American grave goods, sacred items and items taken from protected land. Many auction houses have tightened their policies and some no longer handle certain categories at all. Read the current policy of any platform before you buy or list. A listing that's live today is not proof that it complies.
Learning more
A good way to engage with Native American material culture is through tribal museums, cultural centers and books written with tribal input, rather than by acquiring sensitive objects. Contemporary Native artists also sell their own work directly, which supports living communities.
Frequently asked questions
Does NAGPRA apply to private collectors?
Parts of it do. Its trafficking provision applies to anyone who sells, buys, uses for profit or transports for sale Native American human remains without the right of possession, or cultural items obtained in violation of the Act. Its repatriation duties apply mainly to museums and federal agencies.
Is it legal to buy Native American arrowheads?
Stone tools found lawfully on private land with permission can often be bought and sold, subject to state law and marketplace policy. Points from federal, tribal or state land, or from burials, are a different matter. Ask for find location and permission records.
What should I do if I find human remains in an inherited collection?
Do not sell, give away or discard them. Store them respectfully, stop handling them, and get advice from a lawyer, your state archaeologist or SHPO, and the National NAGPRA program about appropriate steps.
Can I sell sacred or ceremonial objects at auction?
This is high-risk legally and ethically. Some items may be objects of cultural patrimony that no individual could have sold, and federal law restricts trafficking and export of items obtained in violation of law. Get legal advice and consider consulting the tribe.
Where can I find official NAGPRA information?
The National Park Service administers the National NAGPRA Program and publishes the law, regulations, and guidance on its website.
The bottom line
NAGPRA exists because Native American graves and sacred objects were taken, sold and displayed for generations without consent. For collectors, the rules translate into a few clear habits: never trade in human remains, steer clear of burial and sacred items, demand documentation for everything else, and treat tribes as the people best placed to answer questions about their own heritage. If you're unsure, the respectful choice and the legally safer choice are almost always the same one.
