Chapter 73 covers articles of iron or steel, including seamless steel pipes, welded steel pipes, hollow profiles, pipe fittings, wire ropes, metal products, etc. This chapter ranges from raw materials to finished products, involving multiple industrial fields, and is an important commodity category in international trade. Heading 7304 covers seamless steel pipes and hollow profiles, including seamless pipes used for oil drilling, geological drilling, mechanical processing, pipeline transportation, etc. Under this heading, further subdivision is made according to use and material. The first 2 digits 73 represent Chapter 73, articles of iron or steel; digits 3-4, 04, represent heading 7304, i.e., seamless steel pipes and hollow profiles; digits 5-6, 29, represent subheading 730429, specifically referring to other seamless pipes for drilling. This subheading is distinguished from 730422 (seamless pipes of stainless steel for drilling) and 730423 (seamless pipes of other alloy steel for drilling), emphasizing seamless pipes for drilling of non-stainless, non-alloy steel. The commodity is a seamless pipe for drilling, but the material is neither stainless steel nor alloy steel, so it is classified under 730429. If it were made of stainless steel, it should be classified under 730422; if made of other alloy steel, it should be classified under 730423. Correct classification depends on material and use.

Heading
Heading 7304 covers seamless steel pipes and hollow profiles, including seamless pipes used for oil drilling, geological drilling, mechanical processing, pipeline transportation, etc. Under this heading, further subdivision is made according to use and material.
Digit Breakdown
The first 2 digits 73 represent Chapter 73, articles of iron or steel; digits 3-4, 04, represent heading 7304, i.e., seamless steel pipes and hollow profiles; digits 5-6, 29, represent subheading 730429, specifically referring to other seamless pipes for drilling. This subheading is distinguished from 730422 (seamless pipes of stainless steel for drilling) and 730423 (seamless pipes of other alloy steel for drilling), emphasizing seamless pipes for drilling of non-stainless, non-alloy steel.
Classification Basis
The commodity is a seamless pipe for drilling, but the material is neither stainless steel nor alloy steel, so it is classified under 730429. If it were made of stainless steel, it should be classified under 730422; if made of other alloy steel, it should be classified under 730423. Correct classification depends on material and use.
📝 Declaration Elements
Product Name: The standard name of the declared commodity should accurately reflect the commodity attributes, such as "seamless steel pipe for drilling." Material: Declare the specific material, such as "non-alloy steel," "carbon steel," etc., and indicate the grade or chemical composition. Specifications and Model: Declare outer diameter, wall thickness, length, and other dimensions, as well as the model. Use: Clearly declare use for drilling (such as oil drilling, geological drilling), distinguishing it from other uses. Processing Method: Declare the production process of the seamless pipe, such as hot rolling, cold drawing, etc. Brand: Declare the brand or manufacturer; if there is no brand, fill in "none." Quantity and Unit: Declare the transaction quantity and legal unit of measurement (kilograms), and indicate other units such as meters. Product Name: Seamless steel pipe for drilling; Material: Non-alloy steel, grade 20#; Specifications: Outer diameter 89mm, wall thickness 6mm, length 6m; Use: For oil drilling; Processing Method: Hot rolled; Brand: None; Quantity: 10000 kilograms. Failure to indicate "for drilling," resulting in misclassification under other seamless pipe subheadings. Material declaration not specific, failing to distinguish non-alloy steel, stainless steel, or alloy steel. Incomplete specification declaration, lacking outer diameter or wall thickness, affecting classification.
Product Name
The standard name of the declared commodity should accurately reflect the commodity attributes, such as "seamless steel pipe for drilling."
⚠️ Misreported as "seamless pipe" or "steel pipe" without indicating the use.
Material
Declare the specific material, such as "non-alloy steel," "carbon steel," etc., and indicate the grade or chemical composition.
⚠️ Only writing "steel" or "iron" without distinguishing alloy from non-alloy.
Specifications and Model
Declare outer diameter, wall thickness, length, and other dimensions, as well as the model.
⚠️ Omitting wall thickness or outer diameter, causing classification difficulties.
Use
Clearly declare use for drilling (such as oil drilling, geological drilling), distinguishing it from other uses.
⚠️ Vaguely writing "industrial use" without specifying drilling.
Processing Method
Declare the production process of the seamless pipe, such as hot rolling, cold drawing, etc.
⚠️ Misreporting as welded pipe or failing to indicate seamless.
Brand
Declare the brand or manufacturer; if there is no brand, fill in "none."
⚠️ Confusing brand with manufacturer or omitting it.
Quantity and Unit
Declare the transaction quantity and legal unit of measurement (kilograms), and indicate other units such as meters.
⚠️ Incorrect unit, such as reporting only "pieces" without converting to weight.
The core basis for classification is: 1. The commodity is a seamless pipe; 2. The use is for drilling; 3. The material is non-alloy steel (not stainless steel, not other alloy steel). All three conditions must be met simultaneously to classify under 730429. If it is stainless steel or alloy steel, it is classified under 730422 or 730423. 730422 Seamless pipes of stainless steel for drilling: The material is stainless steel, whereas 730429 is non-alloy steel. 730423 Seamless pipes of other alloy steel for drilling: The material is other alloy steel, whereas 730429 is non-alloy steel. 730419 Other seamless pipes of non-alloy steel: The use is not for drilling, such as pipeline transportation, mechanical processing, etc. 730431 Cold-drawn seamless pipes of non-alloy steel: The processing method is cold drawing, and the use for drilling is not specified. Is it confirmed to be a seamless pipe? Is the use for drilling? Is the material non-alloy steel? Are the specifications and model completely declared? Is it confused with stainless steel or alloy steel?
