A toy with batteries in it falls under two sets of rules. One covers moving lithium cells through the carrier network. The other, Reese's Law, covers how button-cell toys are packaged.
Fulfillment.com scans finished, sealed battery-operated toys at pick and again at pack, and packs them to survive the trip. Two separate sets of rules apply to these toys. Lithium cells are hazardous materials in transport under DOT 49 CFR 171-180, classed UN3480 on their own and UN3481 in equipment. Reese's Law sets child-resistant packaging and warnings for toys with button-cell and coin batteries. Which parts apply depends on your cells.

The first set of rules is about transport. A lithium cell counts as hazardous material whenever it moves, and a carrier will usually hold a shipment whose classification, documentation, marking or packaging falls short of what the regulation asks for.
The second is about the product a child picks up. A toy with a button-cell or coin battery has to reach the buyer in child-resistant packaging with the right warnings, because a swallowed coin cell can badly hurt a small child. Different rules govern each, so a toy that meets one can still fall short of the other.
Most of what we do for a battery toy is the same work we do across toys & games fulfillment. How the battery rules apply turns on your cells and the way they ship, so there's no fixed answer we can give before we see them.
Both are public rules, and both apply to the product itself.
In the United States, lithium batteries are regulated hazardous materials for transport under DOT 49 CFR 171-180, the federal hazardous-materials regulations. Two United Nations classifications cover toys. UN3480 is for lithium batteries shipped by themselves, such as spare cells sold loose. UN3481 is for lithium batteries shipped inside equipment or packed with it, which describes most battery-operated toys, since the cells are already installed.
The classification decides what documentation, packaging and markings the shipment needs. When a SKU is labeled and packed for the wrong code, the carrier typically holds it. That is a common reason a carrier holds a battery shipment, and matching each SKU to its correct code helps avoid it.
Reese's Law is a United States law requiring child-resistant packaging and clear warnings on consumer products that contain button-cell or coin batteries, toys included. Young children can swallow those small cells, and the law exists to keep them out of reach.
It works apart from the transport rules. DOT 49 CFR 171-180 covers how a cell moves through the carrier network. Reese's Law covers the packaging and warnings on the sealed retail unit that ends up within a child's reach. A toy can ship as a perfectly compliant lithium package and still fall short of Reese's Law on the shelf, or the other way round, so each one gets checked on its own.
A battery toy is also a children's product, so the testing, certificate and tracking-label rules that cover every toy cover it too. Our guide to children's product safety handling explains each of those documents. The lithium code and the Reese's Law packaging are the two that turn on the battery itself.
Picking, packing and shipping a battery toy is the same work we do for any SKU. The battery rules are the part that changes from one line to the next.
We do this on every battery SKU. We scan every unit at pick and again at pack against the exact SKU on the order, so two toys in look-alike boxes don't get swapped. Multi-component units are counted so every part is in the box, and electronic and multi-component units are packed to stand up to a crushed box and the shocks of transit. Battery toys run on the same systems as the rest of your catalog: BestOMS for orders, Deposco running the warehouse behind it, and Dropstream connecting your store and marketplaces. Orders leave from several warehouses, and 1-3 day ground from them reaches 99.77% of the US.
What depends on your cells. The lithium classification and the child-resistant packaging turn on your exact cells and how they ship, and no 3PL should promise a general answer. Bring your cell types and watt-hour ratings, and we'll go through each SKU with you, matching it to UN3480 or UN3481 with the right documentation and packaging.
Testing and certification stay with the maker. We're a fulfillment company. Manufacturing, testing, certifying and issuing Children's Product Certificates are outside our work. Battery testing and packaging certification belong to the manufacturer or importer. We handle the finished unit, which arrives already compliant, and we settle how we receive your line when we quote.
Batteries turn up all over a toy catalog. These are the places they usually sit:
Every one of these gets the same scanning, counting and protective packing. What differs is the battery paperwork and packaging each one needs.
Oversized, freight-class battery units can go by parcel, LTL or FTL. The carrier and mode are settled at quote, and they move through our freight and heavy-unit handling service. Our guide to oversized and ride-on toys follows a ride-on from start to finish.
The warehouse work is the same as for any finished, sealed toy. The 3PL takes it in, gives it a shelf location, scans it when it is picked and again when it is packed, and sends it with the right carrier and service. Two separate sets of rules apply on top of that. Lithium cells are hazardous materials in transport under DOT 49 CFR 171-180, classed UN3480 when they ship on their own and UN3481 when they ship in or with equipment. Reese's Law sets child-resistant packaging and warning requirements for toys with button-cell or coin batteries. Ask any 3PL how it handles each set of rules for your exact cells. When you ask us for a quote, our team goes through the classification, the paperwork and the packaging checks for your products with you.
Both are United Nations transport classifications for lithium batteries under DOT 49 CFR 171-180. What separates them is whether the cell ships inside something. UN3480 covers batteries shipped by themselves, such as a tray of spare cells sold loose. UN3481 covers batteries shipped inside equipment or packed with it, and that is most battery-operated toys, since the cells are already in the unit. The code sets the documentation, packaging and markings the shipment has to carry. A carrier can hold a SKU sent under the wrong code.
Reese's Law is a United States law covering consumer products that contain button-cell or coin batteries, toys included. It requires child-resistant packaging and warning labels, because a small child can swallow one of those cells. It has nothing to do with lithium transport rules. DOT 49 CFR 171-180 governs how a cell travels through the carrier network, and Reese's Law governs the packaging and warnings on the sealed retail unit a child can get hold of. Getting that packaging right is the manufacturer's or importer's job. If you want to know what a receiving check on your button-cell products would involve, ask our team.
The same way as the rest of a toy catalog. Each version has its own barcoded location, and a unit is scanned when it's picked and again when it's packed. Two remote-control cars in near-identical boxes can't swap places when the barcode has to match the order. Electronic units are packed to stand up to a crushed box and the knocks of transit.
A carrier typically holds a lithium shipment when its classification, documentation, marking or packaging doesn't match what DOT 49 CFR 171-180 and the carrier require for that SKU. Getting the UN3480 or UN3481 classification, the documentation and the packaging right before the unit moves helps avoid it. What's right depends on your cells and how each SKU ships. Bring the classification and documentation for each SKU when you ask for a quote. Our team will work out with you whether and how each one can move, before the first unit ships.
No. What we handle is the finished, sealed toy or game. We are a 3PL, not a manufacturer or a testing lab, so we don't manufacture, test or certify products, and we don't issue Children's Product Certificates. Battery testing and Reese's Law packaging certification belong to the manufacturer or importer. Those rules are requirements on the product, not on the warehouse. How we receive your battery SKUs and Reese's Law packaged units is settled for your line when we quote.
