Harmonized System Code Classification

The first two digits "73" in the HS code represent iron and steel articles.

Specifically, this chapter covers the following main contents:

• Steel structural components: For example, bridges, buildings, towers, etc.
• Cast iron products: For example, pipes, pipe fittings, radiators, etc.
• Steel products: For example, steel plates, steel pipes, steel wires, nails, bolts, nuts, etc.
• Other steel products: For example, springs, chains, fasteners, tools, etc.

Reason for classification:

The establishment of the "73" chapter is to classify and manage various products made primarily of iron and steel. These products typically have the following characteristics:

• Main material is iron or steel: The core component of the product is iron or steel.
• Wide range of applications: Iron and steel products are widely used in construction, machinery, transportation, energy, and other industries.
• Different manufacturing processes and product forms: Iron and steel products can be manufactured through casting, forging, rolling, welding, and other processes, and can take various forms and functions.

Therefore, the first two digits "73" in the HS code are used to identify and classify all products made primarily of iron or steel.

If you can provide a more specific HS code (e.g., 7304, 7310, etc.), I can provide a more detailed classification explanation.

Explanation of the first four digits: 7321: Stoves, ranges, grills, cooking utensils (including cooking utensils with central heating auxiliary boilers), barbecue grills, fire pits, gas stoves, heat-insulating panels, and similar non-electric household appliances, as well as parts thereof made of iron or steel.

Explanation of the six digits: Classification: Stoves, ranges, grills, cooking utensils (including cooking utensils with central heating auxiliary boilers), barbecue grills, fire pits, gas stoves, heat-insulating panels, and similar non-electric household appliances, and their parts.

Specific meaning: Refers to non-electric household appliances such as stoves, ranges, grills, cooking utensils, and their parts, including cooking utensils with central heating auxiliary boilers, as well as barbecue grills, fire pits, gas stoves, heat-insulating panels, etc. It is further subdivided into the category of "other" parts.

Explanation of the 8-10 digits: hscode: 7321906040 Classification: Stoves, ranges, grills, cooking utensils (including cooking utensils with central heating auxiliary boilers), barbecue grills, fire pits, gas stove heads, heat-insulating utensils, and similar non-electric household appliances, and their parts made of iron or steel: --> Parts: --> Other --> Parts of cooking utensils and heat-insulating utensils: --> Shelves and racks for cooking ovens Explanation: This HS code belongs to a detailed classification of parts of non-electric household appliances such as stoves and ranges. Specifically, it refers to shelves and racks for cooking ovens made of iron or steel.

Examples of products: * Cooking oven shelves and racks * Steel parts for stoves * Steel components for barbecue grills * Steel parts for gas stoves * Steel parts for heat-insulating utensils
