Flammable office items
Aerosol & Limited-Quantity Flammable Handling for Office Supplies
Updated October 2026
More of an office catalog is flammable than most people expect, from air-dusters to solvent markers. These items ship under the DOT limited-quantity rules, so a warehouse has to know which SKUs they are before the first order goes out.
Several common office items are regulated hazardous materials, among them:
- aerosols, Class 2 gases under UN1950
- spray adhesives
- rubber cement
- solvent markers, which like rubber cement are Class 3 flammable liquids
Many of them ship under the DOT limited-quantity exception, which took over the handling once called ORM-D. The exception has its own rules for marking each box, for how much goes in it and for how it travels. Following them starts with classifying each SKU when it arrives at the warehouse.

On the office shelf
More of the office shelf is flammable than people expect
Think about what sits in an ordinary office:
- compressed-air dusters for the keyboards
- spray adhesive for mount board
- rubber cement at the art desk
- dry-erase and permanent solvent markers
- a can of multi-surface cleaner in the breakroom
Every one of these is a flammable hazardous material, and when a fulfillment warehouse ships it, it travels as a regulated parcel. A warehouse that treats every SKU the same will sooner or later send one out the wrong way.
The rules
How limited-quantity flammables actually ship
These rules are public, and they apply whichever 3PL ships your products.
They are Class 2 aerosols or Class 3 flammable liquids
These items carry a propellant or a flammable solvent, and correction fluid has a solvent too. An aerosol can is UN1950, a Class 2 gas (Division 2.1 when flammable, and some dusters are 2.2), while rubber cement, solvent markers and correction fluid are Class 3 flammable liquids. The class is what brings in the rules on marking, quantity and routing. Often the hardest step is noticing it at all. On an office shelf, a flammable SKU rarely looks any different from the non-flammable one next to it.
Many ship under the limited-quantity exception
Regulators allow a limited-quantity exception for small amounts in each inner package. It lowers the requirements for shipping these flammables, though it doesn't remove them. ORM-D (Other Regulated Material, Domestic) was a designation for consumer goods that has since been retired, and the handling it covered now falls under the limited-quantity rules. The exception is what makes an office-sized can of air-duster affordable to ship.
The square-on-point limited-quantity mark
Each package shipped under the exception has the limited-quantity mark on its outer box. The mark is a square turned on its point, with the top and bottom corners filled in solid. It tells every carrier and handler along the way that the box holds a regulated limited-quantity material. A box that needs the mark and ships without it is out of compliance.
A cap per package, and ground before air
The exception caps how much flammable material can go in one package. Ground is the preferred route, because the rules for flammables are stricter in the air. An item that moves fine by truck under the exception can be limited or refused on a plane.
The exact marks, limits and routing restrictions are set by the regulations and change over time. What applies to a given SKU and shipment comes from the rules in force when it ships.
In the warehouse
What compliant flammable handling requires of a 3PL
Every warehouse works under the same rules. What differs is whether a flammable SKU ships the right way on every order, at volume.
- Classification at receiving. The work starts before any order ships. We give each SKU a handling class as it's received, so the system knows a flammable is flammable from the first day, rather than someone noticing at the packing bench. Our pick-and-pack system reads that class and points each flammable toward the route it's cleared for, rather than into an ordinary parcel.
- The mark and the quantity limit. Every package moving under the limited-quantity exception needs the square-on-point mark and has to stay within the per-package limit. That has to be right on every shipment, and setting it up once isn't enough.
- Routing by ground. Limited-quantity flammables travel by ground, so how one ships has to follow its class, even when another service would cost less. The same team that picks and packs your catalog arranges this routing with the carriers, as part of our freight and heavy-unit handling service.
Before you sign
What's settled, and what to confirm for your catalog
Some of this is the same for every catalog we take on. Product comes to us finished and sealed. We don't make, refill or remanufacture office or school supplies, and we never fill an aerosol or decant an adhesive; that work belongs to a manufacturer, and we're a 3PL. We give every SKU a handling class at receiving. We pick by the single unit, the pack, the case or the pallet, and we scan every pick, which is there to catch a mix-up between two office SKUs that look alike. Packing keeps carton size and the freight leg in view, and the whole flow is tracked in BestOMS, with Deposco behind it and Dropstream connecting your channels.
The rest varies from one warehouse to the next, so put three questions to any office-supplies 3PL, us included:
- what its in-house hazmat and flammable shipping covers
- whether its system stops a flammable from shipping the wrong way on its own, or relies on a packer reading the flag
- exactly which flammable classes it will and won't accept

Questions about shipping flammable office supplies
How do aerosols and flammable office supplies ship?
Aerosols such as air-dusters and spray adhesive are Class 2 gases under UN1950 (Division 2.1 when flammable, and some dusters are 2.2), and solvent items such as rubber cement and markers are Class 3 flammable liquids. Many of them can ship under the DOT limited-quantity exception, which took over the handling once called ORM-D. Each box carries the square-on-point limited-quantity mark and stays under a cap on how much it holds. Ground is the preferred route, because flammables face tighter limits in the air. Getting it right starts with classifying each SKU, so a flammable goes out the way its class allows rather than as an ordinary parcel. Bring us your SKU list and our team will go through the class, the mark and the shipping route each item needs.
What is the limited-quantity exception, and what was ORM-D?
It's a set of rules for shipping small amounts of certain hazardous materials in each inner package, and many flammable office items fall under it. It lowers the requirements for shipping them, but it doesn't remove them. ORM-D, short for Other Regulated Material, Domestic, was a related label for consumer goods. It has been retired, and the goods it covered now ship under the limited-quantity rules. Those rules call for the square-on-point mark on the outer box, a cap on how much each package holds, and ground as the preferred route. So the routine is the same as it was: classify the item, mark the box, stay under the limit and send it by ground.
Why are aerosols and solvent markers routed by ground rather than air?
They're flammable, and the rules for flammable hazardous materials are stricter on a plane than on a truck. An item that ships fine by ground under the limited-quantity exception can be restricted or refused by air, so ground is the default. A shipment typically gets refused or fined when one of these goes out as an ordinary parcel, with no mark and by the wrong service.
How does Fulfillment.com keep a flammable SKU from shipping the wrong way?
It starts when the SKU arrives. We give it a handling class at receiving, and our pick-and-pack system reads that class when an order comes in. Once we've classified a flammable, the system points it toward the route it's cleared for rather than an ordinary parcel. Ask any partner, us included, whether its system actually blocks the wrong route or relies on a packer reading the flag. Our team will show you how the flag is acted on for your SKUs.
Does Fulfillment.com handle limited-quantity flammables in-house?
Any partner shipping flammable office items has to classify them, put the limited-quantity mark on each box, keep to the quantity limits and send them by ground. On our side, every SKU gets a handling class at receiving, and our pick-and-pack system reads it. Which flammable items we can take on depends on the SKUs and the volume, so we start from your catalog. Send us your aerosol, adhesive and solvent-marker SKUs. Our team will go through how each one would be marked, packed and shipped.
Does Fulfillment.com manufacture or refill any of these products?
No. We fulfill finished, sealed office and school supplies, and we don't make, refill or remanufacture anything. We also don't fill, decant or change an aerosol, adhesive or marker. When we kit, we put finished units together in a box. Our work starts when the sealed product arrives from your supplier.
Have aerosols, adhesives, or solvent markers in your catalog?
Send us the SKUs and how many you sell, and our team will go through the flammable class and handling for each one. The quote costs nothing and holds you to nothing.
