Hawaii cat converter desk board license path and real costs

Last updated 2026-08-21

Do you need a license for a cat converter desk in Hawaii?

Yes. If you buy and sell used catalytic converters as a business in Hawaii, you need a county used motor vehicle parts dealer license under HRS chapter 289, plus a Hawaii general excise tax license. There is no separate statewide cat converter card.

HRS §289-2 is blunt. It says: "No person shall engage in the business of purchasing, selling, bartering, exchanging, or otherwise dealing in used motor vehicle parts or accessories unless the person first obtains a license as provided in this chapter from the treasurer or director of finance of the county in which the person has the person's principal place of business." ^[1]

A used catalytic converter is a used motor vehicle part. That is the whole jurisdictional hook. The 2022 legislature also passed S.B. 2182, enacted as Act 124, after converter theft blew up. That measure added converter-specific purchase rules on top of the old used-parts chapter. ^[2] Read the current HRS 289 text the week you apply. Later sessions can change the buyer's duties, and a 2022 PDF is not a substitute for the statute now in force.

GET sits in a different stack. Hawaii taxes the privilege of doing business. You file with the Department of Taxation, not with the county parts clerk. ^[3] If you form an LLC or a corporation, you also register that entity with DCCA Business Registration. ^[4] Those papers do not replace the chapter 289 license. They stack.

A one-off sale of a converter from a car you actually own is a different fact pattern. A cat converter desk in Hawaii that buys from the public is the business chapter 289 is aimed at. I would not take walk-in sellers until the county license is in hand. The stolen-property risk is the part people shrug off, then do not shrug off.

If you also talk and act like a scrap dealer, read HRS chapter 445. The record statute there is HRS §445-233. ^[5] Some desks need both mindsets even if only one license hangs on the wall. Ask the county clerk, out loud, whether they also expect a scrap-dealer license for converter traffic. Get the answer in writing if they will give it.

How much does a cat converter desk cost in Hawaii?

No honest single startup price exists for a Hawaii cat converter desk. The license fee is county-set. Rent is local. Insurance is quoted, not published. The only statewide tax figures I will pin down are the GET rates. Confirm every other dollar with the county director of finance and with the Department of Taxation before you build a spreadsheet you will regret.

Hawaii Department of Taxation states the general excise tax rates as 0.5 percent on wholesale business and 4 percent on retail business. ^[3] HRS §237-13 is the statute that levies those privilege taxes on gross proceeds. ^[6] Counties may add a surcharge on the same receipts under HRS §237-8.6. ^[7] Do not copy a surcharge rate from a blog post. Pull the current table.

I will not invent the county used-parts license fee. HRS chapter 289 sends you to the treasurer or director of finance in the county of your principal place of business. ^[1] Call that office in Honolulu, Hilo, Wailuku, or Lihue. Ask for the current used motor vehicle parts and accessories dealer application, the fee, and whether they want a bond or a premises walk-through. If they want a bond, that premium is part of the real cost. If they want an inspection, fix the bay before they arrive.

Other first-year money that is real even when nobody publishes a tidy average:

Entity papers, if you want an LLC, paid to DCCA. Confirm today's filing amount on the Business Registration fee schedule. Do not use a number you memorized in 2019. ^[4]

An EIN from IRS, free if you apply on the IRS site. ^[8]

Rent and buildout in a zone that allows this use. Honolulu industrial space costs more than a Hilo warehouse. Get written quotes on the actual bay. Anyone selling you a single "average Hawaii shop rent" without a lease is guessing.

A camera that stores files, a scale you can defend in a dispute, lockable storage, and basic PPE. Buy boring gear.

Insurance. Ask a Hawaii broker for general liability and property on the metal. I will not invent a premium.

I would not spend money on a tourist-strip storefront. Sellers will find a tidy industrial bay. I would spend money on a buy process that logs VIN, seller ID, and photos so you can answer a detective without scrolling through texts. That process costs less than one bad converter.

How long does a cat converter desk take in Hawaii?

No statute promises a Hawaii cat converter desk will be licensed in 10 days or in 90. HRS 289 does not publish a statewide processing clock. Timeline is county practice, plus zoning, plus whatever tax accounts you still need. Nobody has good public data on median turnaround. I will not fake one.

An EIN can come back the same day on the IRS online application. ^[8] GET licensing runs through the Department of Taxation. Ask that department for current processing. Do not treat a forum's "two weeks" as a promise. ^[3]

The long pole is usually the county 289 license and the premises. If the county inspects, if zoning is wrong, or if your application is thin, you wait. I would apply only after I have a real address an inspector can visit. A virtual mailbox is a bad plan for a parts dealer license that is tied to a principal place of business in that county. ^[1]

A sequence that does not waste months looks like this. Confirm zoning with county planning for that specific lot. Form the entity if you want one, then get the EIN. Apply for GET. File the HRS 289 application with the county that has your shop. Sit still on public buys until the county license is actually issued.

If a salesperson promises a date, they are selling. The statute does not back them. Incomplete applications are how people stall themselves. Bring the lease, the ID, the entity papers, and the tax IDs the clerk asked for. Then ask how they notify you. Then wait without buying converters from strangers in a parking lot.

Who is the Hawaii cat converter desk board?

Hawaii does not have a standalone catalytic converter board. The "board" people mean is the county treasurer or director of finance, who issues the chapter 289 used motor vehicle parts dealer license. ^[1] That is a county counter, not a Honolulu hearing room full of commissioners.

Four counties, four counters. City and County of Honolulu. County of Hawaii. County of Maui. County of Kauai. Your principal place of business decides which one. If you try to run the desk in a different county than the one on the license, you are asking for a problem you will not talk your way out of.

State agencies still matter. They just are not a converter board. Department of Taxation handles GET. ^[3] DCCA handles entity papers. ^[4] County police and prosecutors handle stolen converters. EPA still cares about tampering, including on Oahu. ^[9][10]

When someone online says "call the Hawaii DMV board," they are mixing this up with mainland motor vehicle dealer boards. Hawaii's county finance office is the licensing desk for used parts. Call that office by name. Ask for the used motor vehicle parts and accessories dealer application, not for a "cat permit." If the clerk does not know what you mean, say chapter 289.

HRS §289-3 is the application section. It is where the county gets to ask who you are and where the shop sits. ^[14] HRS §289-7 is the inspection hook. The treasurer or director of finance can look at the place and the records. ^[15] Build the desk as if someone with a badge will stand in it. Because they can.

What paper do you need for each converter buy in Hawaii?

Keep more paper than you think you need. HRS chapter 289 requires licensed dealers to keep records the county can inspect. ^[11] HRS §445-233 is the scrap-dealer record statute. Read both current sections before you design a ticket. ^[5] I will not invent a hold period or a mandatory field list here, because those lines move when the legislature amends the chapter.

Pull HRS 289 and 445 the week you open. Ask the county licensing clerk what they want to see in a file. Write down what they say. If Act 124's converter rules added fields, those fields are not optional just because your mainland buddy skips them. ^[2]

A file I would actually keep, even if a statute is quieter than California's stack:

Seller's government photo ID copy.

A signed statement that they own the converter or have authority to sell it.

Vehicle year, make, model, and VIN when the converter came off a vehicle.

Date, time, amount, and payment method.

Clear photos of the converter, any stamp or serial, and the seller standing there.

A log you can sort by VIN and by date.

That log is the part desks skip, then need at 4 p.m. on a Friday. If you want a fill-in VIN log and a theft-compliance checklist rather than inventing a spreadsheet at midnight, CatConPath publishes a $179 one-time VIN-Log + Theft-Compliance Kit at /start. That is optional stationery. It is not a Hawaii license and it does not speak for the county.

Act 124 existed because converters were walking off cars and moving through weak desks. ^[2] If your file cannot answer who sold you this, and from what car, you are the weak desk. Retain records for as long as the current statute says, then keep them longer. Storage is cheap. A subpoena is not.

Can you pay cash for catalytic converters in Hawaii?

Do not assume cash is legal. Hawaii spent the 2022 session tightening converter purchases. ^[2] Payment rules live in the current HRS 289 and 445 text, not in a group chat. Read those sections. Then ask the county licensing desk how they expect you to pay sellers. If the clerk will email the rule, save the email.

If a statute requires a check or another traceable method, follow that method even when a seller complains. A seller who only wants cash is a seller I would walk away from. The converter is not worth the story you will tell a detective.

Federal Form 8300 still exists if you receive more than $10,000 in cash in a trade or business. IRS publishes the form and the about page. ^[12] If Hawaii already pushed you off cash on the buy side, you may rarely hit that form when you purchase converters. Know it anyway. A desk can still take cash in other trades.

I would pay in a way that creates a bank record tied to the seller's name. That is basic theft hygiene. It is also how you prove you were not the fence if the serial comes back hot a month later. Advertisements that scream cash for cats are how you attract the exact seller you do not want. Skip the ad. Keep the paper.

What federal rules still apply to a Hawaii cat converter desk?

A county license does not wash out federal law. The Clean Air Act still applies in Honolulu Harbor the same way it applies in Oakland. 42 U.S.C. §7522(a)(3) makes it illegal, in part, "for any person knowingly to remove or render inoperative any such device or element of design after such sale and delivery to the ultimate purchaser." ^[9]

EPA's tampering policy is the document staff actually point to when they explain defeat devices and aftermarket removal. ^[10] A desk that only buys already-cut converters for metal recovery is not the same fact pattern as a shop that cuts converters off customers' daily drivers. Do not blur those jobs on your website. If you offer cut-off service on a vehicle that must stay legal on Hawaii roads, you have a federal problem, bigger than any county one.

Recycling scrap metal has its own EPA lane. 40 CFR 261.6 addresses recyclable materials, including scrap metal that is recycled. ^[13] That is a waste classification rule. It is not a license to ignore county buy records, and it is not permission to strip a street-legal car.

I would not advertise that you unbolt cats while someone waits unless counsel has walked you through both HRS 289 and §7522. The metal desk and the tampering shop are different businesses. On an island, word travels. So do EPA referrals.

Does Honolulu licensing differ from Hawaii, Maui, and Kauai counties?

The statute is statewide. The counter is local. That is the whole map. You apply where your principal place of business sits. ^[1] GET is state-level, with a possible county surcharge on the same receipts. ^[3][7] Zoning, inspections, hours, and how picky the clerk is will differ. Honolulu has more theft volume and more eyes. A Hilo desk still needs the same chapter 289 license.

Maui County includes Molokai and Lanai. If your "desk" is a van and a phone, you still need a principal place of business the county can license. Do not romanticize a beach-park meetup. That is how stolen converters move, and it is a terrible look when the photo hits a group chat.

I would pick the county I actually live and work in. Licensing in one county and buying in another without advice is a way to get two offices angry at you. If you later open a second bay, ask whether you need another 289 license. Do not guess.

Item	What HRS already says	What you confirm locally
Principal place of business	License comes from that county's treasurer or director of finance [1]	Exact street address the inspector will visit
Application content	HRS §289-3 governs the application [14]	Current form, ID, entity papers, photos
Records and inspection	HRS §289-6 and §289-7 [11][15]	How the clerk wants the buy book laid out
GET	State tax on business receipts [3][6]	Current county surcharge [7]
Converter buy rules	Act 124 amended the purchase stack [2]	Payment method and any hold practice they enforce

Use that table as a call script. Then go stand at the counter. Email only gets you so far when the file is physical.

What taxes does a Hawaii cat converter desk actually pay?

GET is the tax that surprises mainland operators. It is not a sales tax you tack on at the register and forget. It is a privilege tax on gross receipts from business in the State. Hawaii Department of Taxation's GET page is the plain-language version. HRS §237-13 is the levy. ^[3][6]

Hawaii's general excise tax rates are 0.5 percent on wholesale business and 4 percent on retail business, per the Department of Taxation. ^[3] If you sell converters to a licensed refiner or another wholesaler, you may belong in the wholesale bucket. If you sell a converter to a walk-in who is not in that class, you may be in retail. I am not your tax counsel. Misclassified GET is an expensive surprise. Pay a Hawaii tax professional for one hour before you file the first periodic return.

County surcharge can sit on top of the state rate. HRS §237-8.6 is the surcharge statute. ^[7] Confirm whether your county's surcharge is in force on the month you open. Rates have moved. Old flyers lie.

Federal income tax still exists. So does the EIN you should have gotten before the first buy. ^[8] If you later have employees, you have withholding and unemployment accounts I will not fake my way through in this guide. Calendar the GET filings the day the license arrives. Late GET is a boring way to hurt a thin island margin.

What first-year spending is worth it in Hawaii?

First year is records, a legal bay, and not buying stolen metal. It is not a new logo.

Waste of money: a retail counter on a tourist street. Waste of money: a consultant who cannot name HRS 289. Waste of money: converters with no VIN and no ID because the price looked good on a Tuesday.

Spend on a lockable hold area. Spend on a camera that actually keeps files. Spend on a written buy script your helper cannot freelance. Train whoever is at the window to say no. The first year is when a sloppy buy becomes a detective at the door.

Shipping to a mainland refiner is normal for island desks. Get the refiner's intake rules in writing. Weigh on a scale you trust. Photograph sealed drums or pallets before they leave the dock. Island freight will eat thin margins. Run the numbers before you promise sellers a Honolulu price you saw on a mainland app.

Compare paper cultures if you already worked somewhere else. California is the heavy West Coast stack. Read cat converter desk board in California as contrast, not as a form you can file in Honolulu. Alaska is the other isolated market, and the freight problem will feel familiar: cat converter desk board in Alaska. Arizona and Florida are what a lot of videos describe. They are not Hawaii. Skim cat converter desk board in Arizona and cat converter desk board in Florida only so you stop pasting their checklists into your county packet.

How does Hawaii compare to other states on cat desks?

Hawaii licenses cat converter desks at the county level under HRS chapter 289, not through a statewide cat converter board. ^[1] That one sentence is the difference people miss when they copy a California DMV packet or an Arizona scrap form.

California asks for more dealer and scrap paper than most operators want to think about. If that is the system you already know, start with cat converter desk board in California and then throw most of it out for Hawaii purposes. Keep the habit of VIN logging. Lose the assumption that a state board will mail you a converter endorsement.

Inland states can look easier on YouTube. They also have their own theft statutes and buy books. cat converter desk board in Colorado and cat converter desk board in Illinois are useful only as a reminder that "used parts" and "scrap" are often two licenses, two desks, two inspections. Georgia's path is another county-and-state mash people confuse with Hawaii: cat converter desk board in Georgia.

What Hawaii uniquely adds is geography. You cannot drive a hot converter to the next state by dinner. You can air-cargo a lot of metal if you get sloppy. Freight records become part of your defense file. So do refiner settlement sheets. Keep both.

What should you confirm with the county before you open?

Print this and take it to the finance counter. Do not open the buy window until you have answers.

Is the license title still used motor vehicle parts and accessories dealer under chapter 289?

What is today's fee, and how do they want it paid?

Do they require a bond, fingerprints, or a premises inspection? ^[14][15]

What payment methods are they enforcing on converter buys after Act 124? ^[2]

How long must you keep the buy book? ^[11]

Do you also need a scrap dealer license under chapter 445? ^[5]

What address must appear on the license, and will they accept a storage unit?

Then call the Department of Taxation and ask how they want converter sales coded for GET, and whether your county surcharge applies this month. ^[3][7] Confirm. Do not infer.

CatConPath is an independent publisher, not a law firm and not a service company. Nothing here is an approval, a timeline, or a fee quote. If you still want the optional VIN-log kit after you have the county forms, it lives at /start. It does not replace the application in your hand.

I would rather you open six weeks late with a clean file than open Friday with a folding table and a wad of cash. Hawaii is a small pond. The same detectives will know your bay.

Frequently asked questions

Do you need a license for cat converter desk in Hawaii?

Yes. A business that buys and sells used catalytic converters needs a county used motor vehicle parts dealer license under HRS chapter 289, issued by that county's treasurer or director of finance. You also need a Hawaii GET license from the Department of Taxation. There is no separate statewide converter permit. Confirm both before you buy from the public.

How much does cat converter desk cost in Hawaii?

No honest statewide startup figure exists. Confirm the chapter 289 fee with your county finance office. GET rates are 0.5 percent wholesale and 4 percent retail at the state level, plus any county surcharge. Add entity filing if you form an LLC, rent in a legal zone, insurance, and basic buy-desk gear. I will not invent the county license fee.

How long does cat converter desk take in Hawaii?

HRS 289 does not set a statewide processing clock. EIN can be same-day from IRS. GET timing is whatever the Department of Taxation is doing when you file. The county used-parts license and zoning are usually the slow part. Apply with a real inspectable address. Do not buy from the public while the application sits.

Is there a state catalytic converter dealer board in Hawaii?

No. Hawaii has no standalone cat converter board. The licensing desk is the county treasurer or director of finance under HRS chapter 289. Department of Taxation handles GET. DCCA handles entity registration. Police handle stolen converters. If someone tells you to call a state DMV board for a converter endorsement, they are describing another state.

Do I need a GET license if I only sell converters to a mainland refiner?

If you are doing business in Hawaii, you still deal with GET. Selling to a mainland refiner may put you in the wholesale rate class, which is 0.5 percent at the state level, but that is a classification question for a Hawaii tax professional. The Department of Taxation's GET page and HRS §237-13 are the starting documents. Confirm. Do not guess from a forum.

Can I run a cat converter desk from my house in Hawaii?

Only if zoning allows it and the county will license that address as your principal place of business under HRS 289. Most residential lots will fail one or both tests. A virtual mailbox is a weak plan for a parts dealer license the county can inspect. Get planning and the finance clerk on the record before you spend on cameras and a scale.

Do I need a scrap metal license as well as the used parts license?

Ask the county. HRS chapter 289 is the used motor vehicle parts dealer license. HRS chapter 445 is the scrap-dealer chapter, and §445-233 is the record statute. Converter traffic can touch both mindsets. I would not assume one license covers every way you describe the business on a website. Get the clerk's answer in writing if they will give it.

What happens if I buy a stolen catalytic converter in Hawaii?

You can lose the metal, the money, and a lot of time with police. A chapter 289 license does not make a hot converter clean. Keep seller ID, VIN, photos, and a traceable payment so you can show you were not the fence. If a seller will not identify the car, I would not buy. Island desks are easy to find twice.

Can a tourist sell me a catalytic converter in Hawaii?

Treat this as a high-risk buy even if some ID is produced. You still need whatever the current HRS 289 and 445 rules require, including identity and ownership paper. A visitor with a converter and no vehicle story is a walk-away for me. Confirm with the county how they want nonresident sellers documented before you invent a workaround.

Do I need an EIN for a Hawaii cat desk?

Get one. IRS issues EINs online at no charge, and banks, refiners, and tax filings will ask. A sole prop can sometimes use a Social Security number, but an EIN keeps your personal number off refiner packets. Apply on the IRS EIN page, not through a paid middleman. It is one of the few free, fast steps in this stack.

Are used catalytic converters hazardous waste in Hawaii?

Used converters sold for metal recovery are generally handled as scrap metal, and 40 CFR 261.6 is the federal recyclable-materials rule people cite. That is not a Hawaii permit, and it is not advice for fluids, batteries, or other shop waste. If you drain or store other wastes, you have a different problem. Ask counsel or an environmental consultant before you store drums of mixed junk.

Can I advertise cash for cats in Honolulu?

I would not. Hawaii tightened converter purchase rules in 2022, and cash is the payment method theft rings like. Read current HRS 289 and 445, then ask the county how they expect you to pay sellers. Even if a loophole existed, a cash ad is how you attract the seller you do not want. Use a traceable method and keep the bank record.

Does Hawaii require a surety bond for a used parts dealer?

HRS chapter 289 sends the license to the county, and bond practice can sit in the county's application packet rather than in a single sentence I can quote with confidence. Ask the treasurer or director of finance whether a bond is required today, in what amount, and on what form. If they want one, budget the premium before you sign a lease.

Where do I apply in Honolulu versus Hilo?

Apply with the treasurer or director of finance in the county of your principal place of business. Honolulu is the City and County of Honolulu. Hilo is County of Hawaii. Maui County is based in Wailuku. Kauai is Lihue. Call that finance office and ask for the used motor vehicle parts and accessories dealer application under HRS 289. Do not mail a packet to the wrong island.
