Chapter 84 covers nuclear reactors, boilers, machinery, mechanical appliances and parts thereof, and is one of the largest industrial product chapters in the HS classification system. This chapter includes power machinery, agricultural machinery, machine tools, office equipment, automatic data processing equipment, bearings, transmission devices, etc., as well as molds used for processing materials such as metal, plastics, and rubber. As a special mold for plastics processing, blow molds belong to the mold-type goods of this chapter. Heading 8480 specifically refers to all kinds of molding boxes, mold bases, molds for casting; molds for metal, hard metals, glass, mineral materials, rubber or plastics. This heading covers molds used for shaping various materials, including metal casting molds, glass forming molds, plastic injection molds, blow molds, compression molds, etc. Blow molds are used for forming hollow products such as plastic bottles and containers, and are therefore classified under this heading. Code 848030 is a six-digit subheading: the first 2 digits "84" represent Chapter 84, i.e., nuclear reactors, boilers, machinery, mechanical appliances and parts thereof; digits 3-4 "80" represent heading 8480, i.e., all kinds of molds and molding boxes; digits 5-6 "30" represent subheading 848030, specifically blow molds. This subheading is further subdivided into blow molds, distinct from other molds for plastics or rubber (such as injection molds, compression molds, etc.). Therefore, 848030 fully indicates blow molding molds used for processing plastics or rubber. This product is a blow mold, specifically used for blow molding hollow plastic products (such as bottles and drums). According to HS classification rules, molds are classified under 8480 according to the material being processed and the molding method. Blow molds belong to molds for plastics, and the subheading explicitly lists "blow molds," so they are classified under 848030. They are not classified under 848071 (injection molds) or 848079 (other molds for plastics or rubber), because blow molding and injection molding are different processes, and the subheading has a specific listing.

Product name: The Chinese and English names of the declared goods should be accurately described as "blow mold" or "Blow mold," avoiding the vague use of "mold." Use: Explain what products the mold is used to produce, such as "used to produce PET plastic bottles," "used to produce HDPE chemical drums," etc., and it must be specific to the type of article. Brand: Fill in the brand or manufacturer name of the mold; if there is no brand, indicate "no brand." Model: Fill in the model or specification number of the mold, which should be consistent with the physical nameplate. Material: The main material of the mold body, such as "aluminum alloy," "stainless steel," "beryllium copper," etc., which affects classification and value. Processing method: Explain the forming process, such as "blow molding," and indicate whether it is extrusion blow molding, injection blow molding, or stretch blow molding. Applicable plastic type: The plastic material suitable for the mold, such as PET, HDPE, PP, PVC, etc. Whether mold base is included: Declare whether the mold includes complete components such as the mold base and core, which affects classification and customs valuation. Customs declaration example: Product name: Blow mold Use: Used to produce 500ml PET plastic bottles Brand: Sidel Model: SBO 14 Material: Aluminum alloy Processing method: Stretch blow molding Applicable plastic: PET Whether mold base is included: Yes Specification: One set including mold base and core Remarks: This mold is used on a blow molding machine to produce beverage packaging bottles. Mistakenly classifying blow molds under 848071 (injection molds), because the molding principles are different. Failure to state the blow molding process at declaration, leading customs to question the classification. Declaring mold parts (such as cores) separately instead of classifying them as a complete mold set.

Core basis for classification: According to General Rules 1 and 6 for the interpretation of the HS, blow molds belong to a specifically listed subheading under heading 8480. First, determine that the goods are molds used for plastics processing; second, the molding method is blow molding, not injection or compression molding; finally, subheading 848030 explicitly lists "blow molds," so they are classified under this code. If the mold is general-purpose or used for other materials, it may be classified under other subheadings. 848071 Injection molds: Injection molds are used for injection molding, where plastic is injected into a closed mold; blow molds are used for hollow blow molding, where a parison is inflated in the mold. The processes are different, so the subheadings are different. 848079 Other molds for plastics or rubber: This subheading covers compression molds, rotational molds, and other molds that are neither blow molds nor injection molds. Blow molds have a specific listing and should be classified under 848030 first. 848020 Mold bases: A mold base is the base or bottom plate of a mold and does not include the cavity; a blow mold is a complete mold including the cavity and base plate. 848050 Molds for glass: Molds for glass are used for glass forming, and their materials and processes differ from plastic blow molds, so they are classified under different subheadings. 847710 Injection molding machines: Injection molding machines are plastics processing machinery, while blow molds are molds installed on blow molding machines; their functions are different. Is it clearly a blow molding process? Is it used for plastic or rubber materials? Does it include a complete cavity? Is it distinguished from injection molds and compression molds? Is it declared as a complete mold set?

What is the difference in HS codes between blow molds and injection molds? Blow molds are classified under 848030, and injection molds under 848071. The difference lies in the molding process: blow molding places a thermoplastic parison in a mold and inflates it to form hollow products; injection molding injects molten plastic into a closed mold for solid or complex-shaped products. The process must be accurately described at declaration to avoid confusion. Among the declaration elements for blow molds, which are most prone to error? Common errors include: use description too broad (such as "plastic products") without specifying bottles, drums, etc.; processing method not stating "blow molding"; material only stating "metal" without specifying the alloy. Detailed filling is recommended to ensure consistency with the actual item and avoid customs questions. If a blow mold is imported together with a blow molding machine, how should it be classified? According to classification rules, the machine and the mold should be classified separately. Blow molding machines are classified under 8477, and molds under 848030. If the mold is declared together as an accessory of the machine but does not constitute the essential character of the complete machine, it should still be declared separately. Separate customs declaration is recommended to avoid classification errors. How should parts of blow molds (such as cores) be classified? If mold parts are dedicated parts and do not constitute a complete mold, they should be classified as mold parts, usually under the corresponding subheading of 8480. However, if the parts are imported together with the mold and are clearly components of a complete mold set, it is recommended to classify them as a complete mold under 848030. The specific determination should be based on the actual state. How can I check the import tariff rate for blow molds? Tariff rates vary by country, trade agreement, origin, etc. It is recommended to check the latest rates through the official website of the customs administration, the International Trade Single Window, or by consulting a professional customs broker. Also pay attention to preferential rates under free trade agreements such as RCEP and the China-Korea FTA. What should be noted when exporting blow molds with regard to the HS code? When exporting, confirm whether the importing country's HS code is consistent with China's; the first six digits are usually the same, but the last four may differ. Also note export control conditions, such as whether an export license or dual-use items are involved. It is recommended to confirm the code with the foreign customer in advance to avoid customs clearance obstacles. Is the classification of blow molds affected by material? HS code 848030 mainly classifies by function (blow molding), and material does not affect the subheading, but it may affect customs valuation and origin. Whether the mold is aluminum, steel, or beryllium copper, as long as it is used for blow molding, it is classified under 848030. However, the material must be declared truthfully to facilitate customs valuation. If a blow mold is used to produce non-plastic products (such as glass), how should it be classified? If it is used for glass blow molding, it should be classified under 848050 (molds for glass), not 848030. 848030 specifically refers to blow molds for plastics or rubber. Therefore, the correct subheading must be selected according to the material being processed.
