Harmonized System Code Classification

The first two digits of the HS code "73" represent steel products.

Specifically, this chapter includes the following main contents:

• Steel structures: 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 of steel. These products usually have the following characteristics:

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

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

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

First four digits explanation: HS code: 7310

Classification description: Containers made of iron or steel, including cans, drums, boxes, etc., for any material (excluding compressed or liquefied gases), with a capacity not exceeding 300 liters, whether lined or insulated or not, but not equipped with mechanical or thermal equipment.

Detailed explanation: This HS code covers various iron or steel containers, such as cans, drums, boxes, etc., which are used for storing and transporting various materials, but cannot be used for compressed or liquefied gases. The capacity limit is no more than 300 liters. These containers can be lined or insulated, but cannot be equipped with any mechanical or thermal equipment.

6-digit explanation: Classification: Iron or steel containers

Meaning: Applies to iron or steel tanks, drums, cans, boxes, and similar containers for any material (excluding compressed or liquefied gases), with a capacity not exceeding 300 liters, whether lined or insulated or not, but not equipped with mechanical or thermal equipment.

• Capacity of 50 liters or more --> Other

8-10 digit explanation: HS code: 7310100005 Classification: Iron or steel containers, with a capacity not exceeding 300 liters, whether lined or insulated or not, but not equipped with mechanical or thermal equipment: --> Capacity of 50 liters or more --> Reusable stainless steel drums, whether pressurized or not, belonging to the type described in the statistical note 1 of this chapter. Explanation: This HS code corresponds to iron or steel containers with a capacity not exceeding 300 liters and a capacity of 50 liters or more. Specifically, it refers to reusable stainless steel drums, whether pressurized or not, which belong to the type described in statistical note 1 of this chapter.

Product examples: * Stainless steel drum (50L) * Reusable steel container (100L) * Steel can (200L) * Steel box (300L)
