Scrap Metal Rules and High-Theft Items
Metal recycling is regulated more tightly than any other resale trade, because the goods can be destroyed in an afternoon. Cash limits, mailed payments, ownership documents for a listed set of items and a separate hold on detached converters all follow from that.

The rule in short
Secondary metals recyclers operate under a scheme separate from general secondhand dealing. Statutes restrict cash payment above a threshold and prohibit it for a listed class of restricted metals, require payment by check mailed to the seller or by electronic transfer, require proof of ownership for listed high-theft items, and impose extra holds on detached catalytic converters.
Metals recycling operates under its own statutory scheme, tighter than general secondhand dealing. Cash payment is capped or prohibited, listed high-theft items require documented ownership, and detached catalytic converters attract restrictions of their own.
The reason is the nature of the goods. A stolen ring can be recovered from a display case weeks later. A stolen length of copper pipe stops existing as soon as it is processed, so the controls are placed on the transaction rather than on the item.
A separate scheme
States that regulate this trade generally place it in a distinct part of the statute. Florida separates secondary metals recyclers from secondhand dealers, with its own definitions, record requirements, payment rules, hold notices and penalties. Washington regulates scrap metal businesses in a dedicated chapter. California addresses junk dealers and recyclers within the secondhand goods chapter but under a separate article with different obligations.
The practical consequence is that a business doing both must satisfy both. A shop that buys jewelry and also buys scrap gold is operating under two sets of records, two reporting streams and two payment regimes at once. The general dealer obligations are covered under secondhand dealer registration; nothing here replaces them.
How payment must be made
Payment method is the central control. Florida prohibits a recycler from entering a cash transaction above a stated amount for regulated metals property, and prohibits cash in any amount for restricted regulated metals property. Payment above the threshold must be by check issued to and payable to the seller, and payment for restricted metals must be by such a check or by electronic payment to the seller's own bank account or their employer's.
The delivery of the payment is regulated too. Checks must be mailed to the seller's street address on file rather than handed over, mailing to a post office box is prohibited, and the payment must be sent within a short period after the transaction. Exceptions exist for registered charities, public bodies acting officially, and commercial vendors who present proof of status. California similarly restricts when and how a junk dealer or recycler may pay for nonferrous material.
| Category | Payment rule | Additional condition |
|---|---|---|
| Ferrous metals | Fewest restrictions, subject to record and hours rules | Identification and transaction record still required |
| Regulated nonferrous metals | Cash permitted only below a stated threshold | Above it, a check issued and mailed to the seller |
| Restricted regulated metals | No cash in any amount | Check mailed to the street address, or electronic transfer |
| Detached catalytic converters | Treated as restricted, with proof of ownership | An additional retention period after purchase |
| Sales by charities and public bodies | Commonly exempt from the payment restrictions | Proof of the exempt status must be presented and kept |
The restricted list
States name the items that are stolen most often rather than legislating in general terms. Florida's list includes a detached catalytic converter or any nonferrous part of one unless purchased as part of a motor vehicle, metallic wire that has been burned in whole or in part to remove insulation, brass or bronze fire department connection and control valves, commercial backflow preventer valves, shopping carts, brass water meters, storm grates and sprinkler components.
For any item on that list a recycler must obtain reasonable proof that the seller owns the property, which may include a receipt or bill of sale, or proof that the seller is an employee, agent or contractor authorized to sell on the owner's behalf, which may include a signed letter on the owner's letterhead dated within a recent period. The document is kept with the record, because it is the first thing an investigator asks for.
Wire burned to remove insulation appears on restricted lists across states because there is almost no lawful reason to present it that way. A yard that buys it without documented ownership is not merely breaching a payment rule; it is buying the one item that most reliably indicates the metal came from somewhere it should not have. Refusing the load is the only safe response.
Identification is captured on the same terms as elsewhere in the trade, and in several states more tightly. Washington prohibits a scrap metal business from purchasing nonferrous metal property from anyone who cannot produce current government-issued photographic identification, and prohibits buying commercial metal property unless the seller holds a commercial account or can prove ownership through written documentation. The identification requirements common to the wider trade are set out under buying from a minor and identification rules.
Where and when the deal happens
Several states control the circumstances of the purchase as tightly as the payment. Florida prohibits buying regulated, restricted or ferrous metals outside stated daytime hours, prohibits buying from a seller who presents property that was not transported in a motor vehicle, and prohibits buying from any location other than a fixed location. It also bars buying from a person using another name, a person under eighteen, or a person visibly under the influence.
The vehicle requirement is easy to misread as bureaucratic. Its function is to produce an identifiable vehicle, recorded on the transaction form, which can be matched against reports of thefts. The same reasoning drives the fixed location rule: a mobile buyer leaves no premises for an inspector to visit and no records to examine.
Exemptions cover counterparties whose origin is already documented. Florida excludes purchases from registered charitable and similar organizations, from law enforcement officers acting officially, from trustees in bankruptcy, executors, administrators and receivers who present proof, from public officials acting under judicial process, from sales under court process, and from manufacturing, industrial and commercial vendors generating regulated materials in the ordinary course of business. Each of those depends on proof presented at the time.
Records, holds and penalties
Recyclers keep both a paper record and an electronic record of every purchase, and transmit the electronic record to the designated law enforcement official by a set time on the following business day. Florida requires the transmitted record to exclude the price paid, and provides that a recycler transmitting electronically need not also deliver paper copies, while allowing an official to request the original for a criminal investigation. Officers may inspect purchased metals and records during business hours.
Hold notices operate as they do elsewhere in the trade: an officer with reasonable cause may issue a written notice identifying the items, and the recycler must keep them. Detached catalytic converters carry an additional retention period after purchase, with exceptions for purchases from another recycler or a salvage vehicle dealer. Penalties escalate quickly, with knowing and intentional breaches of the payment or record provisions reaching felony grade in Florida, and a statutory presumption of knowledge where required records were not kept. The parallel hold and claim machinery is described under when the item turns out to be stolen, and the daily transmission duties under reporting transactions to law enforcement.
Points to carry away
- Metals recycling is regulated under its own statutory part, distinct from general secondhand dealing.
- Cash transactions are capped above a stated amount and prohibited entirely for restricted metals in several states.
- Payment for restricted metals is typically by check mailed to the seller's street address, or by electronic transfer.
- Restricted lists name items such as detached catalytic converters, burned wire, backflow preventers, water meters and manhole covers.
- Reasonable proof of ownership or written authority to sell is required before buying a listed item.
- Detached catalytic converters attract an additional retention period beyond the ordinary rules.
Questions readers ask
Why can a yard not simply pay cash?
Because cash leaves no trace linking the payment to a named person, which is the whole point of the scheme. Statutes therefore cap cash above a stated figure and require payment by check issued to the seller and mailed to the street address on file, or by electronic transfer to an account the seller holds. Mailing to a post office box is prohibited in several states. Exceptions exist for charities, public bodies and commercial vendors who present proof of their status.
What counts as proof of ownership for a restricted item?
Statutes describe it rather than prescribing a single document. Reasonable proof of ownership may include a receipt or a bill of sale. Where the seller is an employee, agent or contractor of the owner, a signed letter on the owner's letterhead, dated within a recent period and authorizing the sale, is commonly accepted. The dealer keeps a copy with the transaction record, because the question a later investigator asks is what the yard actually held at the time of purchase.
Do these rules apply to a household clearing out old pipe?
Yes, in the sense that the yard's obligations do not soften for a small seller. Identification must be presented, the transaction is recorded and reported, payment for restricted metals follows the statutory route, and cash limits apply. What changes is the practical experience: an occasional seller with ordinary household copper will usually be paid by check some days later rather than at the counter, which surprises people who expected to leave with money.

When the Item Turns Out to Be Stolen
Where property held by a shop is believed to be misappropriated, a law enforcement official may place a written hold order freezing disposal for a defined period, extendable only by court order. Separately, an owner may serve notice with a copy of the police report and then petition the court to order return. The shop holds the goods until possession is decided, and statutes commonly direct the person who conveyed them to repay the shop on conviction.
Reporting Transactions to Law Enforcement
Pawnbrokers and secondhand dealers must report each transaction to a designated law enforcement official, commonly the sheriff or local police chief, generally by the end of the next business day. Reports identify the goods in detail and the person who conveyed them. Most states accept or require electronic transmission in place of paper. Refusing inspection or destroying a record early are separate offenses.
Redeeming an Item and What It Costs
A pledgor may redeem pledged goods at any time during the loan period by paying the amount advanced together with the charges permitted by statute. Only the pledgor or a properly authorized representative may collect, and the shop must verify identity. Charges are capped by state law and must have been itemized on the ticket. A lost ticket has a prescribed cure involving written notice and a statement of loss. Refusing to return goods on full payment is a specific offense.
