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 one of the most technology-intensive chapters in the HS classification, involving various types of equipment for the production, conversion, storage, transmission, and utilization of electrical energy. Optical cables, as signal transmission carriers, rely on optical signals rather than traditional electrical signals for their core function, but still fall within the scope of communication transmission equipment, and are therefore classified in this chapter. Heading 8544 covers insulated wire, cable (including coaxial cable) and other insulated electric conductors, whether or not fitted with connectors; optical fibre cables made up of individually sheathed fibres, whether or not assembled with electric conductors or fitted with connectors. This heading includes both traditional metal conductor cables and optical fibre cables, reflecting the diversity of communication transmission media. Optical cables are independent from ordinary wires and cables under this heading because of their special transmission principle and structure. Code 854470 is a six-digit subheading: the first 2 digits '85' represent Chapter 85 (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). Digits 3-4 '44' represent heading 8544 (insulated wire, cable and other insulated electric conductors; optical fibre cables). Digits 5-6 '70' represent subheading 854470, specifically referring to optical fibre cables, i.e., optical fibre cables made up of individually sheathed fibres, whether or not assembled with electric conductors or fitted with connectors. This subheading is not further subdivided, and all types of optical cables are classified under this code. Optical cables are classified under 854470 rather than other codes, mainly because of their structural characteristics: they are made up of individually sheathed fibres and are used to transmit optical signals. They differ from ordinary wires and cables under 8544 (such as 854411, 854419, etc.), which use metal conductors to transmit electrical signals; they also differ from communication equipment under 8517, because optical cables themselves are transmission media rather than terminal equipment. Therefore, 854470 is the only correct classification for optical cables.

Brand Type: Fill in the brand attribute of the optical cable. If there is no brand, fill in 'No Brand'; for export, fill in 'Overseas Brand (OEM production)', etc. Export Preference Status: Fill in according to the actual trade situation, such as 'Export goods do not enjoy preferential tariffs in the final destination country', etc. Purpose: Explain the specific application scenario of the optical cable, such as 'for communication base stations', 'for submarine laying', 'for LAN cabling', etc. Structure Type: Describe the physical structure of the optical cable, such as 'stranded loose tube', 'central loose tube', 'slotted core', etc. Fibre Type: Indicate the fibre mode, such as 'single-mode', 'multi-mode', as well as the number of cores and sheath material. Brand (Chinese and Foreign Names): Fill in the brand name of the optical cable; if there is no brand, fill in 'None'. Model: Fill in the model specification of the optical cable, such as 'GYTA-24B1.3', etc. Whether Fitted with Connectors: Specify whether the optical cable has connectors, such as 'Yes' or 'No'. Brand Type: Overseas Brand (OEM production) Export Preference Status: Export goods do not enjoy preferential tariffs in the final destination country Purpose: for communication base stations Structure Type: stranded loose tube Fibre Type: single-mode, 24 cores, polyethylene sheath Brand: YOFC Model: GYTA-24B1.3 Whether Fitted with Connectors: No Mistakenly classifying optical cable patch cords with connectors under 854470, when they should actually be classified under 854442. Ignoring the 'Structure Type' in the declaration elements, leading to customs questioning the classification. Confusing 'optical cable' with 'optical fibre'; optical fibre is a component of optical cable, and optical fibre imported separately should be classified under 900110.

The core criterion for classification is whether the product is made up of individually sheathed fibres and is used to transmit optical signals. According to HS notes, 854470 specifically refers to optical cables, whether or not assembled with electric conductors or fitted with connectors. However, if the optical cable is already fitted with connectors (i.e., patch cords), it is usually classified under 854442. In addition, it is necessary to distinguish optical cables from ordinary cables: ordinary cables use metal conductors to transmit electrical signals and are classified under other subheadings of 8544; optical cables use optical fibres to transmit optical signals and are classified under 854470. 854442 Electric conductors fitted with connectors: 854442 covers electric conductors fitted with connectors for a voltage not exceeding 1000 V, including optical cable patch cords. If both ends of the optical cable are fitted with connectors, it is classified under 854442 rather than 854470. 854449 Other electric conductors: 854449 covers other electric conductors for a voltage not exceeding 1000 V, but usually refers to metal conductor cables. If the optical cable is not fitted with connectors, it is still classified under 854470. 900110 Optical fibres and optical fibre bundles: 900110 covers optical fibres and optical fibre bundles not made up into cables, while 854470 covers optical cables made up into cables. If a single optical fibre is imported, it should be classified under 900110. 851770 Parts of communication equipment: 851770 covers dedicated parts of communication equipment, but optical cables, as transmission media, are not regarded as equipment parts and are therefore classified under 854470. Is the optical cable made up of individually sheathed fibres? Is it not fitted with connectors? Is it used to transmit optical signals rather than electrical signals? Does it not belong to communication equipment under 8517? Is it made up into a cable rather than a single optical fibre?

What is the difference between optical cable and optical fibre in HS codes? Optical cable is classified under 854470, made up of multiple sheathed fibres into a cable, usually with a sheath and strength members; optical fibre is classified under 900110, and is a single non-cabled glass or plastic fibre. When importing, it is necessary to judge based on the actual form: if it is a coiled optical cable, classify under 854470; if it is a single optical fibre, classify under 900110. Which code should optical cable patch cords with connectors be classified under? Optical cable patch cords with connectors should be classified under 854442, because this subheading covers electric conductors fitted with connectors (including optical cables). If the optical cable is not fitted with connectors, it is classified under 854470. When declaring, it is necessary to specify 'whether fitted with connectors'. How can I check the import tariff rate for optical cables? You can obtain the MFN rate, general rate, and agreement rate by entering HS code 854470 and the country of origin on the official website of the General Administration of Customs, China International Trade Single Window, or professional tariff inquiry platforms. Note that tariff rates may be adjusted with policy changes, and it is recommended to rely on the latest published rates. What are the common classification errors when declaring optical cables? Common errors include: mistakenly classifying optical cable patch cords under 854470 (should be 854442); mistakenly classifying a single optical fibre under 854470 (should be 900110); ignoring the structure type and fibre type in the declaration elements, leading to customs questioning. It is recommended to check item by item against HS notes and declaration elements. How should 'Structure Type' be filled in the declaration elements for optical cables? Structure type refers to the physical construction of the optical cable, such as stranded loose tube, central loose tube, slotted core, etc. When filling in, it should be selected according to the actual structure of the product and should not be filled in arbitrarily. For example, GYTA type optical cable is stranded loose tube and should be filled in as 'stranded loose tube'. Are HS codes the same when exporting optical cables to different countries? The first six digits of the HS code are basically consistent worldwide, and 854470 is the internationally universal code for optical cables. However, countries may add their own subheadings after the six digits, such as China's 10-digit code and the U.S. 10-digit HTS code. When exporting, the corresponding code should be provided according to the requirements of the destination country. Do optical cable tariff rates change frequently? Tariff rates may change due to free trade agreements and trade policy adjustments. For example, the agreement rates between China and ASEAN, Australia, and other countries may differ. It is recommended to check the latest rates through official channels before each customs declaration, or consult a professional customs broker. Is 3C certification required when importing optical cables? Optical cables are generally not within the scope of 3C certification, but if they are used for specific communication equipment or involve safety requirements, other certifications may be required. The specific requirements should be determined according to the requirements of customs and quality inspection authorities. It is recommended to consult the local customs or professional institutions before import.
