NMFC classification for electronics is more involved than shippers expect — "electronics" isn't a single catch-all class. The same base code often splits into 13 density-based sub-codes, so the class depends heavily on actual density. Common electronics codes like electrical appliances/equipment/parts (NMFC 61700) and clocks/watches (48850) can, in theory, land anywhere across the full class 50 to 400 range — which tier actually applies depends entirely on the shipment's measured density. Checking the actual code and measuring density accurately beats estimating a class from experience.

Many electronics codes use density sub-codes — the same base code splits into a dozen or more sub-codes depending on measured density, each mapping to a different class. Under NMFC 61700 (electrical appliances/equipment or parts), the lower the density, the higher the class — light, bulky electronic accessories can cost noticeably more to ship than denser freight of the same weight. Enter accurate dimensions and weight so the system lands on the right density bracket.
Data processing machines or their major components (NMFC 116030) and computer/business-machine housings or cases (NMFC 115985) are two different codes, and both are density-tiered in their own right. Don't file one under the other's code — describe the commodity specifically as a complete unit versus a housing/part, not a generic "electronics" label, and the density still has to be measured accurately either way.
Batteries and cells, including lithium batteries (NMFC 60680), are listed on the 49 CFR hazardous materials table and can't be filed under the same code as ordinary electronic accessories — they require a separate hazmat declaration (UN number, packing group, MSDS). Failing to declare a battery is treated as an undeclared hazmat, with risk and penalties in a different category entirely from a routine reclass.
The codes below are verified against ShipMay's own NMFC database and are meant to illustrate classification logic — the exact code and class that applies to your shipment depends on your actual commodity description, measured density, and the carrier's own review:
| Commodity | NMFC Code | Typical Class Range |
|---|---|---|
| Electrical appliances, equipment, or parts | 61700 | 50 – 400 (13 density tiers) |
| Clocks, watches, and parts | 48850 | 50 – 400 (13 density tiers) |
| Computer/business machine housings or cases | 115985 | 50 – 400 (13 density tiers) |
| Data processing machines, systems, or components | 116030 | 50 – 400 (13 density tiers) |
| Garage/commercial door operators or openers | 126156 | 50 – 400 (13 density tiers) |
| Batteries or cells (including lithium) ⚠️ Hazmat | 60680 | Priced under hazmat rules, not standard density tiers |
Electronics as a category spans a huge range of density, so the same generic "electronics" label can map to very different codes and classes. Recommended approach: search a specific commodity name — "LED display panel," not "electronics" — in the NMFC Lookup tool; weigh and measure accurately, including packaging, so the system matches the right density bracket; confirm separately whether battery-containing products need a hazmat declaration; and when in doubt, send ShipMay the commodity, weight, and dimensions — we can help you check it, though the final code and class are still subject to the applicable NMFC rules and the carrier's review.
