Lithium batteries and high-value, serial-tracked devices need fulfillment built specifically for them. We built serial tracking, carrier-compliant battery shipping, and graded returns into how we run electronics accounts.
Small electronics fulfillment is the controlled storage, serial-number tracking, lithium-battery-aware shipping, and returns disposition of consumer electronic devices. Fulfillment.com ships from an operated, multi-node US network with barcode-verified picking. We work with you to track shipped units by serial number, and confirm battery-SKU watt-hour and UN-number classification, storage-control depth, and returns-grading criteria before your program goes live.
By The Fulfillment.com team.
Consumer electronics are high-value, battery-regulated, and returns-heavy all at once. Electronics-ready fulfillment has to run all three disciplines together: serial tracking, battery classification, and returns disposition.
Devices carry serial numbers that drive warranty, activation, and disputes. A serial or IMEI (the unique ID number printed on a phone or tablet) is what ties a specific shipped unit back to the customer who received it, which is what makes warranty, activation, and dispute resolution provable later. Practices on where and how often that number gets captured and re-checked vary by 3PL (third-party logistics provider); we'll work through capture depth for your SKU mix with you.
Almost every device touches Class 9 dangerous-goods rules. Most ship with or contain a lithium battery, so the UN-number classification, watt-hour thresholds, and air-versus-ground restrictions apply per SKU, and getting them right on every SKU is what keeps a parcel out of a refused-parcel, surcharge, or fine cycle. We work through the classification and lane routing for each SKU with you before your program goes live.
High unit value makes inventory a theft and accuracy target. Shrinkage and mis-ships hit margin directly on expensive stock, which is why the category standard is tighter storage control and more frequent counting for high-value SKUs, on top of barcode-verified picking that catches a mismatch before it ships.
Electronics return at high rates, and a returned device is not automatically resellable. Buyer's remorse, dead-on-arrival units, and defects pile up returned capital. The category standard is to inspect and disposition each return into tiers, commonly sellable, cosmetically flawed but functional, or defective, so recoverable stock gets back to available inventory instead of sitting as stranded cash.
See how the same operator handles the rest of your stack on the full 3PL service catalog, ship cross-border with international fulfillment, or compare the handling profile against the apparel fulfillment overview and the supplement and nutraceutical fulfillment overview.
We fulfill finished, sealed electronic product. We're a 3PL, not a manufacturer, assembler, or repair depot: we don't build, program, reflash, or rework devices unless a named value-added service is confirmed. Kitting means assembling finished units and accessories into a box, not building product.
A device's serial or IMEI is the thread that connects a specific unit to the customer who received it, which is what makes a warranty claim, a device-activation record, or a chargeback dispute resolvable months later instead of a guess. Cables, accessories, and bare component boards commonly ship without a manufacturer serial at all, so the real question for any 3PL is which SKUs get tracked, at what point in the flow, and at what cost. Ask us where your SKU mix falls and we'll walk through capture depth for your program before you commit.
High unit value makes electronics a shrinkage and accuracy target the way lower-value categories are not, so the industry standard is to isolate that stock with tighter access rules and more frequent counting than general inventory gets, on top of a barcode-verified pick that catches a mis-pick before it leaves the building. We'll confirm the specific access-control and cycle-count setup for your program when you request a quote.
Electronics return at rates that make the reverse flow a margin lever, not a back-office afterthought. The category standard is to inspect each returned unit and disposition it into tiers, commonly sellable (A-stock), cosmetically flawed but functional (B-stock), or defective, so sellable units get back to available inventory fast and the rest route out instead of sitting as stranded capital. Ask us how we grade and disposition returns for your product, including any repair, function-test, or refurbishment depth you need.
When a program calls for device-and-accessory bundles, the unit is packed together with its cable, charger, manual, and warranty card so the box ships as one complete kit. Branded unboxing, gift-message inserts, and welcome-kit assembly can be added to a defined spec, and we'll confirm content-verification depth for your bundle with you. Kitting assembles finished, sealed product into a box; we don't build, program, reflash, or rework devices.
Electrostatic discharge invisible to the eye can still degrade or kill a circuit board, which is why the category standard treats static-sensitive units differently from general merchandise, with anti-static handling and packaging built around that risk. Fragile glass-and-screen devices similarly need cushioned, right-sized pack-out sized to the carrier network, not just to the box. The pack profile is set per SKU class, so a bare circuit board and a glass-front tablet are never treated the same way; confirm your handling profile with us for each class.
The device-fulfillment work runs on BestOMS, with Deposco behind it, and Dropstream connecting your storefronts and marketplaces, so orders, inventory, and returns route through one system rather than a patchwork. Inventory is received and shelved across distributed nodes, then orders route and ship from the node closest to your customer.
Lithium batteries are Class 9 dangerous goods, and the single most load-bearing data point per SKU is the watt-hour (Wh) rating, because it drives packing, labeling, documentation, and whether a parcel can fly. Compliant electronics fulfillment runs every battery SKU through the same gate.
Classify by UN number. Standalone lithium-ion cells and batteries are UN3480; standalone lithium-metal are UN3090; lithium-ion in or with equipment is UN3481; lithium-metal in or with equipment is UN3091. Power banks and similar standalone power sources classify as batteries (UN3480 or UN3090), not as equipment containing batteries, so getting that label right on the parcel is the standard to hit.
Gate on watt-hour thresholds. The watt-hour ceiling is mode-specific. For air, the excepted limit is 20 Wh per cell and 100 Wh per battery; a battery over 100 Wh is fully regulated for air, with special packaging, certified handlers, and carrier surcharges, and carries the diamond Class 9 hazard label, while units within the limit use the square lithium-battery mark. Ground (highway or rail) carries a higher excepted ceiling of 300 Wh per battery, but a package using that allowance must be marked forbidden for transport aboard aircraft and vessel. The threshold is set off the unit's own rating, captured per SKU.
Route air versus ground correctly. Air is the most restrictive lane. Standalone lithium-ion (UN3480) must ship at a state of charge not exceeding 30 percent, and a 2026 tightening is reported to extend a mandatory 30 percent state-of-charge limit to lithium-ion packed with equipment (UN3481) over 2.7 Wh as of January 1, 2026. Class 9 hazard labels and durable UN markings are required on every package, with Cargo Aircraft Only labels where applicable, and cells packed to prevent short circuit.
Carry the test evidence. Carriers and customs increasingly require a third-party UN 38.3 test summary, documenting altitude, thermal, vibration, and short-circuit testing, for lithium-ion SKUs; a self-authored safety data sheet is treated as insufficient. The brand supplies the UN 38.3 summary per battery SKU so it travels with the shipment record.
Enforce segregation by data. Compliant fulfillment requires a warehouse system that tracks per-SKU watt-hour rating, packed-with versus contained-in-equipment status, air-versus-ground eligibility, and documentation status, so a fully regulated item cannot ship through a standard small-battery workflow. Whether the Deposco configuration enforces this segregation automatically, and the depth of the in-house hazmat program, are confirmed with you up front rather than assumed.
Every device class needs its own handling: power banks route by battery size, bare circuit boards need static-safe handling, and so on down the list.
Small, high-value, and theft-sensitive: a category that calls for serial tracking, tighter bin-storage control, and pack-out that starts from the unit's watt-hour rating.
Lithium contained in equipment (UN3481): careful handling against ESD (electrostatic discharge, the static jolt that can silently damage circuitry), fragile cushioned pack-out, and accessory kitting for cables and cases when a bundle is ordered.
Commonly serialized for activation and warranty, handled ESD-aware, bundle-assembled when a kit is ordered, with battery-class routing where the unit ships powered.
Small-parcel bin picking and multipack kitting, with the pairing to its parent device checked so the bundle ships complete.
Power banks classify as batteries (UN3480 / UN3090), not equipment. The unit's watt-hour rating is what sets the required marking and the ground-versus-air lane; share the spec and we'll confirm it with you.
High-value stock that calls for serial tracking, lithium-contained pack-out, fragile handling, and staged capacity for launch and Q4 peak volume.
Lithium-heavy and often high-watt-hour, fragile, and high-value: UN-number and watt-hour rating set the shipping lane, alongside serial tracking and reinforced cushioning.
High-value stock calling for serial / IMEI tracking, lithium contained in equipment (UN3481), tighter storage control, and fragile screen-protective pack-out.
Fragile and high-value, lithium-contained where battery-powered: cushioned pack-out and accessory bundling for lenses, straps, and cards when a kit is ordered.
ESD-critical: static-sensitive components call for anti-static handling end to end.
Standalone units classify as UN3480 (lithium-ion) or UN3090 (lithium-metal). Watt-hour rating sets the marking and the shipping lane; confirm your battery specs with us before onboarding.
Serial tracking, tiered grading, and RMA-linked inventory segregation so graded stock stays separated from new.
Serial-number tracking and safe lithium-battery shipping are the two things electronics brands screen a 3PL on hardest, and returns run high enough that how you handle them affects your margin. Here's our approach, alongside the transit numbers we publish.

Serial or IMEI tracking is what makes a specific shipped device traceable back to the customer who received it, which is what makes a warranty claim, activation record, or dispute resolvable later instead of a guess. Not every SKU arrives with a manufacturer serial; an accessory or a bare component board often does not, so tracking coverage and cost vary by SKU class rather than being uniform across a catalog.
Lithium batteries are Class 9 dangerous goods classified by UN number: standalone cells and batteries are UN3480 (lithium-ion) or UN3090 (lithium-metal), batteries in or with equipment are UN3481 or UN3091, and power banks classify as batteries. Watt-hour rating drives packing, labeling, and lane eligibility: for air the excepted ceiling is 20 Wh per cell and 100 Wh per battery, while ground (highway or rail) allows up to 300 Wh per battery on a package marked forbidden aboard aircraft and vessel.
Air is the most restricted lane. Standalone lithium-ion (UN3480) ships at a state of charge of 30 percent or less, and as of January 1, 2026 the same 30 percent limit is reported to extend to lithium-ion packed with equipment (UN3481) over 2.7 Wh. Packages need Class 9 labels, durable UN markings, and short-circuit-safe packing. Eligible SKUs route to ground where air is restricted.
For lithium-ion SKUs, carriers and customs increasingly require a third-party UN 38.3 test summary covering altitude, thermal, vibration, and short-circuit testing; a self-authored safety data sheet is treated as insufficient. Brands provide the UN 38.3 summary for each battery SKU so it travels with the shipment record. Confirm your battery-SKU documentation needs when you request a quote.
High unit value makes electronics a shrinkage and accuracy target the way lower-value categories are not, so the category standard is tighter access control and more frequent counting for that stock, alongside a barcode-verified pick that catches a mismatch before it ships. A published order-accuracy figure specific to devices is added here once ops verifies one.
The category standard is to inspect each returned device and disposition it into tiers, commonly sellable, cosmetically flawed but functional, or defective, so sellable stock gets back to available inventory fast and the rest routes out instead of sitting as dead stock. Repair, function-test, and refurbishment sit beyond that base grading step as a deeper service tier some programs need and others don't.
If your program includes bundles or kits, yes: cable, charger, manual, and warranty-card sets are assembled together so the box ships as one complete kit, with branded unboxing, gift-message inserts, and welcome-kit assembly built to a defined spec and synced to your store platform. We'll confirm content-verification depth for your bundle with you. Kitting assembles finished, sealed product into a box; we don't build, program, or rework devices.
116+ integrations through the Dropstream layer, covering where device brands actually sell: storefronts including Shopify, BigCommerce, WooCommerce, and Magento; marketplaces including Amazon, eBay, Walmart, and TikTok Shop; and EDI (electronic data interchange, the standard format big retailers require for order and invoice data) connectivity for wholesale retail accounts, scoped to your specific trading-partner requirements. Every channel flows into one inventory pool in BestOMS, so serial-tracked stock sells once across DTC, marketplace, and retail and ships barcode-verified from the nearest node.
Same-day shipping runs at 99.84 percent, and 1 to 3 day ground transit reaches 99.77 percent of the US from distributed nodes. Battery SKUs that cannot fly are confirmed for ground routing as part of onboarding, rather than held without a plan.
