Montana’s answer to the kei truck question is the shortest in this series, and it is short because of what the statute leaves out.
MCA 61-3-219 lists every ground on which the department may refuse a certificate of title. There are four: the applicant is not the owner, the application contains a false statement, the applicant failed to furnish a required document, or the vehicle has been reported stolen. Nothing about design, nothing about federal safety standards, nothing about where the vehicle was built or for which market.
Searching the whole of MCA 61-1-101 — the definitions that govern the entire motor vehicle title — for “safety standards” returns nothing. The phrase 49 CFR part 567 appears twice, and both times it is being used to define something a kei truck is not.
So the interesting question in Montana is not whether you can register the truck. It is which of two registration options to take, and how to get a title when your ownership document is Japanese. I research Japan’s used vehicle market from Sapporo; here is what the code and the state’s own title manual say.
The Short Answer
- Full registration, ordinary plates. No kei-specific restriction exists in Montana law.
- No federal safety standards clause anywhere in the title or registration chapters.
- The title manual has a section for “Canadian and Other Foreign Vehicles” that accepts a foreign ownership document.
- No periodic safety inspection and no emissions testing anywhere in the state.
- $28 a year for a vehicle 11 years or older, plus a $7 weight fee — or $87.50 once, permanently.
- Insurance is 25/50/20.
- A Montana plate does not make the truck legal in a state that refuses it.
What Montana Does Not Ask
Two definitions in MCA 61-1-101 decide this, and both go the buyer’s way.
“Motor vehicle” is “a vehicle propelled by its own power and designed or used to transport persons or property on the highways of the state.” That “or used” is doing quiet work: a state that asks only about original design can argue about which market the design was for, while Montana offers a second door. A kei truck is a purpose-built road vehicle by design and a road vehicle in use, so it clears both.
“Motorized nonstandard vehicle” is the exclusion that could have caught it, and this is where 49 CFR part 567 appears. The definition covers a self-propelled vehicle that (i) runs on an engine or electric motor, (ii) has “a wheelbase of less than 40 inches and a wheel diameter of less than 10 inches,” and (iii) does not display a Part 567 certification or a 17-character VIN. All three have to be true. A kei truck fails the second one twice over — the wheelbase is around 74 inches and the wheels are 12 inches — so it is not a motorized nonstandard vehicle, and the exclusion from “motor vehicle” never reaches it.
That drafting deserves a note, because most states that use a Part 567 test use it alone. Montana bundled it with two dimensional tests aimed at pit bikes and pocket scooters, and the bundle is conjunctive. Compare Iowa, where the Part 567 label is a standalone requirement and closes the door by itself, or Idaho, where the bar is written into the registration section in one sentence.
Off-highway does not catch it either
Montana’s “off-highway vehicle” definition covers vehicles “designed for recreation or cross-country travel,” and expressly excludes “motor vehicles designed to transport persons or property on the highways unless the vehicle is used for off-road recreation on public lands.” A kei truck falls outside the off-highway class for the same reason it falls inside the motor vehicle class. In Nevada that same exclusion is a problem, because full registration was believed to be closed and the off-highway route was the only one on offer. In Montana it is simply a tidy result.
The Real Work Is the Title
MCA 61-3-216(4) says an application for a used vehicle “must be accompanied by a certificate of title that is properly assigned by the prior owner.” A Japanese export certificate of deregistration is not a certificate of title, so on the face of the statute you have a problem.
The Motor Vehicle Division’s title manual solves it. Under the heading “Canadian and Other Foreign Vehicles,” the documents required for a foreign title transaction are listed as:
- Application for a Montana title (Form MV1).
- “Canadian registration or Foreign ownership document properly released by the registered owner.”
- The Canadian NVIS form, where one exists — not applicable to a Japanese vehicle.
- Vehicle Identification Number Inspection Certificate (Form MV20).
- Federal DOT declaration HS-7, with the manual noting that “the 25-year period runs from the date of the vehicle’s manufacture.”
- Customs entry documents — “Entry form #7501 is the only acceptable customs entry form and it must be stamped.”
Item 2 is the whole answer. The foreign ownership document is accepted as the ownership document, which means you do not need the bond route at all.
Two traps in that list
The stamp on the 7501. The manual is specific: “The Montana and Idaho region does not participate in the electronic signature process (AKA paperless entry) for CBP documents. An entry document labeled as paperless from another region will not require a stamp.” Read that twice before you clear customs. If your entry is processed in the Montana or Idaho region, get the physical stamp; a paperless entry from a different region is fine as-is. Either way, ask your customs broker for a stamped copy — it costs nothing at the time and is painful to obtain later.
The “export only” line. The manual carries a blanket note: “Anytime ‘export only’ is stamped on a title, it cannot be titled or registered.” That rule is aimed at North American titles branded for export, not at a Japanese deregistration record, which is a cancellation of registration rather than a title. Even so, the wording is broad enough to be worth a phone call to your county treasurer before the truck ships, because a misreading at the counter is a lot easier to prevent than to unwind.
The bond route, and the 30-year line inside it
If the foreign document route somehow fails you, MCA 61-3-208 is the fallback, and it contains a number worth knowing.
The affidavit route is open to a vehicle 30 years old or older, or worth $1,000 or less, with no bond — you establish value and swear an affidavit. A vehicle less than 30 years old and worth more than $1,000 needs a surety bond “in an amount equal to the value of the vehicle,” which runs for three years before a clean title issues.
So Montana’s bond-free line is 30 years, not 25. From 2026 that means model year 1996 and earlier, and the gap slides forward with the calendar exactly as the federal import line does. It is a five-year window in which the bond route costs money and the foreign-document route does not — another reason to keep the Japanese paperwork clean and complete. The 25-year rule guide explains how the month of manufacture is established, which is the same evidence the age question turns on here.
Do not let the grey-market section swallow you
The title manual has a separate chapter headed “New Vehicles NOT Manufactured for U.S. Consumption (Grey Market)”, and it is alarming reading: a DOT performance bond equal to the value of the vehicle, conversion to United States standards by a registered firm, and a wait of “three to six months” for the bond release before a title is issued.
That section is not written for a 25-year import. Its own instructions give it away — it tells the examiner that on the HS-7, “when paragraph 2 is checked there must be an MCO. If paragraph 3 is checked a DOT/EPA release will be required.” A 25-year vehicle checks neither: it enters under box 1, the age exemption, and the whole bond-and-conversion apparatus applies to vehicles that came in as non-conforming imports needing modification.
This is the same structure I found in Nevada’s registration guide, where the bond release letter appears only in the non-conforming subsection. Knowing which section governs is the difference between a counter visit and a six-month wait, so bring the HS-7 with box 1 checked and point at it.
What It Costs
| Item | Amount | Authority |
|---|---|---|
| Annual registration, light vehicle 11 years or older | $28.00 | 61-3-321(2)(a)(iii) |
| Annual weight fee, rated capacity up to 1/2 ton | $7.00 | 61-10-201 |
| Permanent registration, light vehicle 11 years or older | $87.50 once, plus five times the weight fee ($35.00) and five times the local option tax, plus $5.00 insurance verification if no new plates | 61-3-562 |
| Collector’s item, one-time, under 2,850 lb | $5.00 — but the vehicle must be “owned and operated solely as a collector’s item” | 61-3-321(4), 61-3-411 |
| Local option motor vehicle tax | Set by each county; varies | 61-3-537 |
| Safety inspection | None | — |
| Emissions test | None | — |
A kei truck’s rated capacity is 350 kg, about 772 lb, which puts it in the lowest weight bracket in the statute — the $7.00 line.
Which option to take. Annual costs $35 a year before local tax. Permanent costs $87.50 plus $35 plus five years of local option tax, so roughly $122.50 plus local tax, and then nothing for as long as you own the truck. The break-even is under four years, and a kei truck bought at 25 years old is not a vehicle you keep for three. The catch is in 61-3-562(5): permanent registration cannot be transferred to a new owner, so the value dies when you sell. If you intend to keep it, permanent registration is the obvious call.
Montana has no state sales tax, which is the reason you have heard of Montana registration at all. That is a separate subject and mostly not a good one — see below.
Insurance
Montana requires $25,000 for bodily injury or death of one person, $50,000 for two or more persons in any one accident, and $20,000 for property damage, under MCA 61-6-103(1)(b). Written 25/50/20 — the property damage figure is $20,000 rather than the more common $25,000, which is worth catching if you are comparing quotes across states.
Two practical points that apply everywhere. Online quote forms validate VIN length and will refuse a Japanese chassis number, so plan on arranging cover by telephone. And ask for agreed-value or stated-value rather than actual cash value; there is no book value for a 1999 Japanese-market truck, which is exactly why you do not want a total loss settled by a valuation guide.
About the Montana LLC
Because Montana charges no general sales tax, a business has grown up around forming a Montana LLC, titling a vehicle to it, and registering it here from another state. Kei truck buyers hear about it and ask the wrong question, so here is the right one.
A Montana plate does not change what your home state allows. Registration is where the vehicle is on the books; road use is governed by the state whose roads you are on. If you live somewhere that refuses these trucks, a Montana registration does not make the truck legal to drive there — it makes it a vehicle registered in Montana that your state still will not let on its roads. The fifty-state comparison is the page to read first, because the answer you need is about your own state, not this one.
The tax side is not something I can advise on, and I am not going to pretend otherwise: use tax is owed where the vehicle is used, several states audit for exactly this pattern, and the consequences land on you rather than on the LLC. If you actually live in Montana, none of this applies and the state is one of the cheapest and simplest places in the country to keep one of these trucks legal.
The Process, in Order
- Import in your own name and get the stamped CBP Form 7501. Ask the broker for it at the time, not later.
- Keep the HS-7 with box 1 checked — the 25-year age exemption. This is the document that keeps you out of the grey-market chapter.
- Keep the Japanese export deregistration certificate, properly released by the registered owner. This is your ownership document.
- Get Form MV20, the VIN inspection certificate, completed in Montana.
- File Form MV1 with your county treasurer, and decide annual or permanent registration at the counter.
- Ask about the “export only” note before the truck ships, so nobody has to improvise on the day.
What to Buy for Montana
Four-wheel drive, and gear reduction if you can find it. Montana is the state in this series where a kei truck’s actual job — ranch tracks, feed runs, hunting access, snow — matches what the vehicle was designed for in rural Japan. The off-road guide has the measured 4WD share by model from my Japanese-market sample and explains which models offer a low range.
Corrosion, but for a different reason than the coasts. Montana salts and sands, and the winters are long. Prefer stock from warm, dry prefectures and read the auction sheet for C codes, which mark corrosion through metal rather than surface blemishes. Because Montana has no inspection, nobody will stop you registering a rusty truck — which means the discipline has to come from you.
Check the heater and the cold-start behavior before shipping. A tired battery and a weak starter that go unnoticed in Kyushu are a different animal at −20°F. Ask the exporter to confirm the truck starts cold and the heater blows hot on every speed.
Think about distance. Montana towns are far apart, and a 660cc truck at sustained highway speed is working hard. These are excellent property and town vehicles and poor interstate vehicles, which is a physics problem rather than a legal one. The Carry guide and the Hijet guide cover what holds up under load.
For reference, the Japanese side of this market as I measured it across 394 trucks: Subaru Sambar ¥370,000, Honda Acty ¥390,000, Mitsubishi Minicab ¥390,000, Suzuki Carry ¥400,000 and Daihatsu Hijet ¥450,000 at the median. The model comparison sets those against United States sale averages, and the landed cost calculator covers the duty, entry and freight.
Montana will not inspect the truck, which puts the entire quality question back on the purchase. CAR FROM JAPAN publishes the inspector’s auction sheet with each vehicle, so the corrosion codes and equipment grades are visible before you bid. My referral code takes $100 off a first purchase: enter KEITRUCK at the order step (referral link).
FAQ
Are kei trucks street legal in Montana?
Yes. Montana has no kei-specific restriction, no federal safety standards clause in its title or registration chapters, and only four statutory grounds for refusing a title — none of which touch the vehicle’s origin or design.
What ownership document does Montana accept?
The Motor Vehicle Division’s title manual lists a “foreign ownership document properly released by the registered owner” among the documents required for a foreign title transaction, alongside Form MV1, the MV20 VIN inspection, the HS-7 and a stamped CBP Form 7501.
Do I need a bond?
Not if the foreign ownership document is accepted. The bond provision at 61-3-208 applies when you cannot produce an assigning title, and it exempts vehicles 30 years old or older or worth $1,000 or less.
Is there an inspection?
Only the VIN inspection on Form MV20. Montana has no periodic safety inspection and no emissions testing.
What does registration cost?
$28 a year for a vehicle 11 years or older, plus a $7 weight fee, plus county local option tax. Or $87.50 once for permanent registration, plus five times the weight fee and five times the local option tax — but that cannot be transferred when you sell.
What insurance is required?
25/50/20 under MCA 61-6-103.
Can I register in Montana if I live somewhere else?
People do, through Montana LLCs, and that is a tax question rather than a kei truck question. What matters here is that a Montana plate does not make the truck legal on the roads of a state that refuses it.
