The shipment is a reel of flexible strip with diodes every few centimetres, a separate driver, and an aluminium channel, all in one carton. Is it a lamp, a luminaire, or parts. The honest answer is that the tariff cares how the set is presented and what is complete at import, and the reel alone and the finished kit do not classify alike.
Start with what crosses the border. A bare LED strip, diodes mounted on a flexible substrate with a power connection, is an electrical article doing light emitting work in an unfinished form. A strip mounted in a channel with diffuser and driver, wired and ready to install, presents as a complete luminaire. A carton of components that becomes a fixture only after installation labour sits between them, and the General Rules for incomplete and unassembled articles decide whether it is classified as the finished fixture or as its parts.
Chapter 94 covers luminaires and lighting fittings, including electric ceiling and wall lights and their recognisable parts. Chapter 85 covers lamps and electrical apparatus, including the light sources themselves. CBP rulings on LED products move between the chapters on exactly this axis: completeness and presentation at import, not the word light printed on the box.
Two components decide many of these files. The driver, the power supply converting mains to the low voltage the strip runs on, is a static converter in its own right when imported separately, under heading 8504. Inside a complete fixture it folds into the fixture's classification. The aluminium channel with diffuser is recognisably a part of a luminaire when its shape and extrusion only serve that purpose, and a general purpose profile when it does not.
Itemize the carton on the worksheet, component by component, with quantities and how they combine. Kits are where entry errors breed: one line for the whole carton at the fixture rate, applied to a shipment that was actually reels of strip with spare drivers, overpays or underpays depending on the mix, and neither error survives a CBP review kindly.
Supplier descriptions call everything a light. Marketing copy calls the strip waterproof, smart, and architectural, none of which classifies anything. The facts that matter are physical: diode type and spacing, substrate, whether the strip is cut to length or a standard reel, connectors fitted or loose, driver included or separate, channel included or not, and the rated voltage of the set as sold.
Photograph the presentation as imported, not the installed result on a showroom wall. Rulings reason from the article in its imported condition. A file full of installation photos argues for a fixture the shipment may not yet have been, which is the fastest way to talk yourself into the wrong chapter with great confidence.
Classify per SKU presentation and freeze it to the bill of materials version. When the supplier starts including the driver in the same carton, or drops the channel, that is a new presentation and a new analysis, even if the retail name never changed. Lighting catalogues churn components quietly and often.
Where a high volume line sits near the chapter boundary, a binding ruling is cheap insurance. LED products also attract Chapter 99 additional duties by subheading for China origin goods, so the chapter decision sets the stack as well as the base rate. Paying a small fee for certainty beats reclassifying two years of reels.

It depends on the presentation at import. Complete luminaires and their recognisable parts sit in chapter 94, while light sources and electrical apparatus sit in chapter 85. A bare reel of strip, a strip with driver and channel as a finished kit, and components shipped separately can each take a different line, which is why the worksheet starts from the carton contents.
By the rules for incomplete and unassembled articles: if the components as presented have the essential character of the finished luminaire, the set classifies as the luminaire. If not, components take their own lines, a driver alone is a static converter under heading 8504. The carton has to be itemised either way, component by component.
Diode type and spacing, substrate and length as imported, connectors fitted or loose, whether the driver and channel are included, and the rated voltage of the set. Photograph the presentation as imported, not the installed result. Supplier marketing language about the product being smart or architectural carries no classification weight.
When a high volume SKU sits near the chapter 85 and 94 boundary, or when its components change presentation between orders. The ruling fixes the line for your product, and because Chapter 99 additional duties attach by subheading, it also fixes the stack. That certainty is cheap next to reclassifying years of entries.
