Chapter 85 covers electrical machinery and equipment and parts thereof; sound recorders and reproducers, television image and sound recorders and reproducers, and parts and accessories of such articles. This chapter is the main chapter for technology-intensive products in the HS classification, involving various types of equipment for the production, conversion, storage, and utilization of electrical energy, including lighting devices such as bulbs and lamps. Goods in this chapter generally operate on electrical or electronic principles, and are distinguished from furniture lamps (non-electrical) of Chapter 94 and glassware of Chapter 70. Heading 8539 covers various electric filament or discharge lamps, including incandescent lamps, discharge tubes (such as fluorescent lamps, halogen lamps, LED lamps, etc.), arc lamps, and parts for electric light sources. This heading mainly targets devices that produce light radiation through electrical energy, regardless of whether their use is for lighting, decoration, signaling, or special industrial purposes. However, it only includes the bulbs themselves, and does not include luminaires (classified under 8539 or 9405) or complete luminaires incorporating bulbs (usually classified under 9405). Code 853978 is a 6-digit subheading with the following structure: the first 2 digits "85" indicate Chapter 85 (electrical machinery and equipment and parts thereof); digits 3-4 "39" indicate heading 8539 (electric filament or discharge lamps); digits 5-6 "78" indicate subheading 8539.78, which in the HS classification specifically refers to "other incandescent lamps," but according to Chinese Customs subheading notes, 8539.78 is further subdivided into incandescent lamps for decorative purposes. Therefore, 853978 as a whole represents "incandescent lamps for decorative purposes." Note: the first 4 digits 8539 are an internationally harmonized heading, and the last 2 digits 78 are the subheading; Chinese Customs may have further 8-10 digit codes on this basis. This product is an incandescent lamp for decorative purposes, whose core function is to emit light by heating a filament with electrical energy, belonging to the incandescent lamp category. Since its use is decorative (such as holiday string lights and decorative light strings) rather than general lighting or industrial use, it is classified under 8539.78 rather than 8539.10 (halogen lamps) or 8539.21 (fluorescent lamps). At the same time, it does not have a luminaire housing or fixture, so it is not classified under 9405.

Product Name: The specific name of the declared product, which should include the words "incandescent lamp for decorative purposes" and indicate the brand and model. Use: Clearly declare for decorative use, such as holiday decoration, ambient lighting, etc., to distinguish it from general lighting. Brand: Fill in the brand name of the bulb (such as Philips, Osram, etc.); if there is no brand, write "no brand." Model: Fill in the model or specification code provided by the manufacturer, such as E27, voltage, power, etc. Power: Declare the rated power of the bulb in watts (W), such as 15W, 25W, etc. Voltage: Declare the rated voltage of the bulb in volts (V), such as 220V. Base Type: Declare the lamp base specification, such as E27, E14, B22, etc.; this affects classification but is not decisive. Packaging Specification: Declare the quantity per carton or per package to facilitate customs statistics and inspection. Product Name: Incandescent lamp for decorative purposes; Use: Holiday decoration; Brand: No brand; Model: E27-15W; Power: 15W; Voltage: 220V; Base Type: E27; Packaging Specification: 100 pcs/box. Misreporting decorative use as general lighting, resulting in classification under 8539.29 or other subheadings. Ignoring the declaration of brand and model, causing customs questions or delays. Incorrect power and voltage units, such as filling in watts as kilowatts.

The core criteria for classification are: 1. The product is an incandescent lamp, i.e., an electric light source that emits light by heating a filament with current; 2. The use is decorative, such as holiday string lights and decorative light strings, rather than general lighting or industrial use; 3. The bulb itself is not assembled with a luminaire; if already assembled into a luminaire, it is classified under 9405. According to HS notes, subheading 8539.78 specifically covers incandescent lamps for decorative purposes, so meeting the above conditions results in classification under 853978. 853929 Other incandescent lamps: 853929 covers other incandescent lamps, usually for general lighting, while 853978 specifically refers to decorative use; use is the core difference. 853910 Halogen lamps: Halogen lamps are a type of incandescent lamp but contain halogen gas and are classified under 8539.10, while incandescent lamps for decorative purposes are usually vacuum or inert gas filled and are not classified here. 940531 Electrical Christmas tree light strings: 9405 covers luminaires; if the bulbs are assembled with light strings into a complete luminaire, they are classified under 9405.31, while 853978 refers only to the bulbs themselves. 853950 Light-emitting diode (LED) lamps: LED lamps use semiconductor light emission and are classified under 8539.50, while incandescent lamps for decorative purposes use thermal radiation light emission, with a different principle. Is it based on the incandescent principle? Is it for decorative use? Is it not assembled into a luminaire? Is it not a halogen lamp? Is it not an LED lamp?

How do I look up the HS code for incandescent lamps for decorative purposes? First determine that the product is an incandescent lamp, then judge by use: if for decorative use, classify under 8539.78; if for general lighting, classify under 8539.29. You may consult the Import and Export Tariff or use a customs classification advance ruling. What is the difference in classification between incandescent lamps for decorative purposes and general lighting bulbs? The main difference is use: incandescent lamps for decorative purposes are classified under 8539.78, and those for general lighting under 8539.29. Customs will judge based on declared use, packaging, sales channels, etc. If the bulb is assembled with a light string, how is it classified? If the bulb is assembled with a light string, wires, etc. into a complete luminaire, such as a Christmas tree light string, it should be classified under 9405.31, not 8539.78. 8539.78 refers only to the bulb itself. Can LED decorative bulbs be classified under 853978? No. LED bulbs use semiconductor light emission and should be classified under 8539.50. 8539.78 applies only to incandescent lamps. What elements need attention when declaring? It is necessary to declare product name, use, brand, model, power, voltage, base type, packaging specification, etc. The use must be clearly stated as decorative; otherwise, it may be classified under other subheadings. What is the import tariff rate for incandescent lamps for decorative purposes? The tariff rate changes according to national policies and trade agreements. It is recommended to consult the latest Import and Export Tariff or ask customs. Usually the MFN rate and general rate differ, and free trade agreement rates may also be relevant. How do I determine whether a bulb is for decorative use? It is mainly based on product design, packaging, sales promotion, etc. If the product is clearly for holiday decoration or ambient lighting and usually has lower power and multiple colors, it can be identified as decorative use. What are the consequences if the code is incorrectly declared during customs declaration? Incorrect declaration may lead to supplementary taxes, fines, credit downgrading, etc. It is recommended to declare truthfully and apply for advance classification if necessary. If uncertain, consult a professional customs broker or customs.
