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 mainly includes various equipment for the production, conversion, storage, transmission, and utilization of electrical energy, such as generators, transformers, batteries, household appliances, communication equipment, etc. Zinc-air batteries, as devices that convert chemical energy into electrical energy, belong to the battery products of this chapter. Heading 8506 covers primary cells and primary batteries. Primary cells are devices that convert chemical energy directly into electrical energy through chemical reactions, are not rechargeable, or are designed for single use. This heading includes various types of primary batteries, such as zinc-carbon batteries, alkaline batteries, silver oxide batteries, lithium primary batteries, and zinc-air batteries. Zinc-air batteries are classified under this heading due to their single-use characteristics. First 2 digits 85: represents Chapter 85, the chapter on electrical equipment. Digits 3-4, 06: represents heading 8506, specifically primary cells and primary batteries. Digits 5-6, 60: represents subheading 8506.60, specifically zinc-air batteries. Hierarchical breakdown: Chapter 85 → Heading 8506 → Subheading 8506.60. This subheading is further subdivided under heading 8506, alongside other primary batteries such as manganese dioxide batteries (8506.10), mercuric oxide batteries (8506.30), silver oxide batteries (8506.40), lithium primary batteries (8506.50), etc. Zinc-air batteries are classified under 8506.60 because they are primary batteries (single-use batteries) and use zinc as the negative electrode and oxygen from the air as the positive active material. They do not meet the reversible charging characteristics of storage batteries (8507), nor do they belong to other subheadings (such as 8506.10 for manganese dioxide batteries). Their unique working principle and structure warrant a separate subheading under heading 8506.

Voltage: Fill in the rated voltage of the battery; zinc-air batteries are typically 1.4V or 1.45V. Use: Explain the main application areas of the battery, such as hearing aids, electronic watches, etc. Contains Mercury: Declare whether the battery contains mercury and whether the mercury content complies with environmental requirements. Product Name: Zinc-air battery; Brand: PowerOne; Model: PR44; Appearance: Button shape; Dimensions: Diameter 11.6mm, height 5.4mm; Voltage: 1.4V; Use: For hearing aids; Contains Mercury: No mercury. Misclassifying zinc-air batteries under 8506.10 (manganese dioxide batteries) due to similar appearance. Failing to declare voltage, causing customs inability to distinguish zinc-air batteries from alkaline batteries. Ignoring mercury content declaration, potentially violating environmental regulations such as the Restriction of Hazardous Substances Directive (RoHS).

The core basis for classification is the electrochemical system of the battery. Zinc-air batteries use zinc as the negative electrode and oxygen from the air as the positive active material, and are primary batteries (single-use batteries), thus classified under heading 8506. Its subheading 8506.60 explicitly lists 'zinc-air batteries', so it is directly classified under this subheading. When classifying, it is necessary to confirm that the battery is not rechargeable and that the positive active material is oxygen from the air, not other chemicals. 8506.10 Manganese dioxide batteries: Manganese dioxide batteries use manganese dioxide as the positive electrode and zinc as the negative electrode; common alkaline batteries and carbon-zinc batteries. Zinc-air batteries use oxygen from the air as the positive active material, with voltage typically 1.4V, while manganese dioxide batteries are 1.5V. 8506.30 Mercuric oxide batteries: Mercuric oxide batteries use mercuric oxide as the positive electrode, with stable voltage but contain mercury, and have been gradually phased out. Zinc-air batteries do not contain mercury, are more environmentally friendly, and have different positive active materials. 8506.40 Silver oxide batteries: Silver oxide batteries use silver oxide as the positive electrode, with voltage 1.55V, commonly used in watches. Zinc-air batteries have voltage 1.4V, and the positive electrode relies on air, with different structure. 8506.50 Lithium primary batteries: Lithium primary batteries use lithium as the negative electrode, with voltage typically 3V, and high energy density. Zinc-air batteries use zinc as the negative electrode, with voltage 1.4V, and the positive electrode needs to contact air. 8507.60 Lithium-ion storage batteries: Lithium-ion storage batteries are secondary batteries, rechargeable. Zinc-air batteries are primary batteries, not rechargeable, and the electrochemical system is completely different. Is the battery a primary battery (not rechargeable)? Is the positive active material oxygen from the air? Is the voltage around 1.4V? Does it contain mercury or other hazardous substances? Is it explicitly listed under subheading 8506.60?

What is the difference in HS codes between zinc-air batteries and alkaline batteries? Zinc-air batteries are classified under 8506.60, while alkaline batteries (manganese dioxide batteries) are classified under 8506.10. The main difference lies in the electrochemical system: zinc-air batteries use oxygen from the air as the positive active material, with voltage typically 1.4V; alkaline batteries use manganese dioxide as the positive electrode, with voltage 1.5V. When declaring, it is necessary to accurately provide voltage and positive electrode material. How to inquire about the import tariff rate for zinc-air batteries? First confirm the HS code is 8506.60, then inquire according to the customs tariff of the destination country. For example, in China Customs' 'Import and Export Tariff', the most-favored-nation rate, general rate, etc. for 8506.60. Tariff rates may change; it is recommended to check the latest rates through the General Administration of Customs website or professional customs declaration systems. What certifications are required for exporting zinc-air batteries? Exporting zinc-air batteries typically requires compliance with the destination country's environmental and safety certifications, such as the EU's RoHS, REACH, the US's UL, FCC, etc. In addition, battery transportation must comply with the International Air Transport Association (IATA) dangerous goods regulations, providing UN38.3 test reports. Specific certification requirements vary by country. How to distinguish zinc-air batteries from silver oxide batteries when declaring? Silver oxide batteries are classified under 8506.40, with voltage 1.55V and positive electrode of silver oxide; zinc-air batteries are classified under 8506.60, with voltage 1.4V and positive electrode relying on air. They may look similar in appearance, but can be distinguished by voltage and positive electrode material. When declaring, information such as model, voltage, and use should be provided. Do zinc-air batteries contain mercury? Modern zinc-air batteries typically do not contain mercury and comply with environmental requirements. However, some older models may contain mercury. When declaring, the mercury content should be truthfully declared, such as 'no mercury' or provide a test report. Batteries containing mercury may be restricted by regulations such as the Minamata Convention on Mercury. Is it possible for zinc-air batteries to be classified under 8507? No. 8507 is for storage batteries (secondary batteries), which are rechargeable. Zinc-air batteries are primary batteries, not rechargeable, so they are classified under 8506. If a battery is designed to be rechargeable (such as zinc-air flow batteries), it may be classified under 8507, but traditional zinc-air batteries are all primary batteries. What should be noted when selling zinc-air batteries through cross-border e-commerce? Attention should be paid to the accuracy of HS code declaration to avoid customs clearance delays due to incorrect classification. At the same time, batteries are dangerous goods and must comply with transportation regulations, providing MSDS and UN38.3 reports. Sales to the EU also require compliance with the Battery Directive and WEEE Directive. In the declaration elements for zinc-air batteries, how should the use be filled in? The use should be specific and clear, such as 'for hearing aids', 'for electronic watches', 'for medical devices', etc. Avoid general filling like 'for electronic products'. Specific use helps customs quickly classify and reduces inspection risks.
