Chapter 84 is the core chapter of electromechanical products in the HS classification, covering nuclear reactors, boilers, machinery, mechanical appliances and their parts. Goods in this chapter are characterized by power drive or mechanical motion, and are used to process materials and perform operations. The scope ranges from household machinery to industrial equipment, but excludes electric tools (Chapter 85), vehicles (Chapter 87) and optical instruments (Chapter 90). This chapter emphasizes mechanical function rather than material properties, and is one of the most technology-intensive chapters in international trade. Heading 8480 covers various molds for casting and molds for shaping metal, hard metals, glass, mineral materials, rubber or plastics. It includes metal casting molds, glass molds, mineral material molds, rubber or plastic molds, etc. Molds are tools used in industrial production to shape articles, causing materials to acquire a specific shape through pressure, temperature or injection. This heading does not distinguish molds by their material composition, but requires that they be specially designed for a specific molding process. The first 2 digits 84: indicates Chapter 84, belonging to machinery, mechanical appliances and their parts. The 3rd-4th digits 80: indicates heading 8480, specifically molds for casting, metal casting molds, glass molds, mineral material molds, rubber or plastic molds. The 5th-6th digits 79: under 8480, subheading 848079 represents molds for plastics or rubber. Note: under heading 8480 there are also 848010 (metal casting molds), 848020 (glass molds), 848030 (mineral material molds), 848041 (injection or compression molds), 848049 (other metal molds), 848050 (glass molds), 848060 (mineral material molds), 848071 (injection or compression molds for plastics or rubber), 848079 (other molds for plastics or rubber). Therefore 848079 specifically refers to plastic or rubber molds other than injection or compression molding, such as blow molds, vacuum forming molds, etc. This product is a plastic mold, used for plastic molding, so it is classified under 8480. Since it is not a metal casting mold, glass mold or mineral material mold, 848010, 848020 and 848030 are excluded. Among plastic or rubber molds, if it is for injection or compression molding, it should be classified under 848071; while 848079 covers plastic or rubber molds for other molding methods, such as blow molding, vacuum forming, extrusion, etc. Therefore, this code applies to plastic molds other than injection and compression types.

Product name: The specific name of the declared goods, which should accurately reflect the mold type, such as "plastic blow mold" or "plastic vacuum forming mold". Use: Explain what plastic products the mold is used to produce, such as "used to produce PET bottles" or "used to produce automotive interior parts". Brand: Fill in the brand or manufacturer name of the mold; if there is no brand, fill in "no brand". Model: Fill in the model or specification of the mold, such as "M-2024-01". Molding method: Clearly specify the molding process of the mold, such as "blow molding", "vacuum forming" or "extrusion". Material: The material of the main parts of the mold, such as "mold steel" or "aluminum alloy". Applicable plastic type: Explain what plastic the mold is used to process, such as "PET", "PP" or "ABS". Example of customs declaration: Product name: Plastic blow mold Use: Used to produce 500ml PET beverage bottles Brand: Sidel Model: SBO-14 Molding method: Blow molding Material: Mold steel Applicable plastic: PET HS code: 8480790090 Declaration date: 2025-03-15 Quantity: 1 set Total price: USD 25,000.00 Mistakenly classifying injection molding molds under 848079, when they should actually be classified under 848071. Failure to specify the molding method, leading to classification disputes. Confusing rubber molds with plastic molds; although both belong to 848079, the declaration elements must be accurate.

The core basis for classification is the mold's molding method and the material being processed. First, according to the notes to HS Chapter 84, molds must be used for material molding. Second, heading 8480 is subdivided by mold type; subheading 848071 targets injection or compression molding molds for plastics or rubber, while 848079 covers plastic or rubber molds for other molding methods. Therefore, the key determination is whether the molding process is injection or compression. If it is blow molding, vacuum forming, extrusion, etc., it is classified under 848079. In addition, it is necessary to confirm whether the mold is used for plastics or rubber, rather than metal, glass, etc. 848071 Injection or compression molds for plastics or rubber: This code is dedicated to plastic/rubber molds for injection molding or compression molding, while 848079 is used for other molding methods, such as blow molding and vacuum forming. 848010 Metal casting molds: Used for metal casting; the mold material and process are different, and it is not applicable to plastic molding. 848020 Glass molds: Dedicated to glass molding, and differs from plastic molds in both material and process. 848030 Mineral material molds: Used for molding mineral materials (such as ceramics and cement), and is not applicable to plastics. 848050 Glass molds (other): Similar to 848020, but may involve different glass molding processes, and is still not applicable to plastics. Confirm whether the mold is used for plastic or rubber molding. Confirm whether the molding method is injection or compression. Confirm whether the mold is used for other materials (metal, glass, etc.). Check whether the declaration elements are complete and accurate. Check the latest customs classification decisions or advance rulings.

How to distinguish 848071 from 848079? 848071 is dedicated to injection molding or compression molding molds for plastics or rubber, while 848079 covers other molding methods, such as blow molding, vacuum forming, extrusion, etc. When declaring, the molding process must be specified; if it is injection or compression, it should be classified under 848071. What are the declaration elements for plastic molds? They mainly include product name, use, brand, model, molding method, material, applicable plastic type, etc. Among them, the molding method is crucial and directly affects classification. If a mold is used for multiple plastics, how should it be declared? The main applicable plastic type should be declared, or all applicable types should be listed. If it cannot be determined, consult customs or provide technical documents. Does the mold material affect classification? The mold material does not affect classification under heading 8480, but may affect the subheading. For example, metal casting molds are classified under 848010, while plastic molds are classified under 848071 or 848079. How are imported used molds classified? Used molds are still classified according to function, but it should be noted that customs may have additional regulatory requirements for used mechanical and electrical products. It is recommended to confirm in advance whether pre-shipment inspection is required. What is the export tax rebate rate for 848079? The rebate rate changes with policy adjustments. It is recommended to check the latest export tax rebate rate database of the State Taxation Administration or consult the local customs. What are the common errors in mold classification? Common errors include: mistakenly classifying injection molds under 848079, confusing rubber molds with plastic molds, failing to specify the molding method, and confusing mold parts with complete molds. How to obtain a customs advance ruling? You may submit an advance ruling application through the official website of the General Administration of Customs or the local customs, providing detailed product information. Customs will issue a ruling within the prescribed time.
