The complete summary table of drill pipe HS codes is as follows:

According to the Chinese Customs Import and Export Tariff, the complete summary of HS codes related to drill pipe is as follows. Different codes correspond to different materials, uses, and processing methods. Please match the code to the appropriate code based on the specific product.

HS Code for Drill Pipe Body:

1. Drill Pipe for Oil and Gas Drilling (Most Common)

HS Code	Product Name	Material Requirements	Outer Diameter	Import Most Favored Nation Tariff Rate	Export Tax Rebate Rate
7304221000	Stainless Steel Drill Pipe	Stainless Steel	≤168.3	4%	0%
7304229000	Other Stainless Steel Drill Pipe	Stainless Steel	>168.3	4%	0%
7304231000	Other Steel Drill Pipe	Non-Stainless Steel (Carbon Steel/Alloy Steel)	≤168.3	4%	0%
7304239000	Other Steel Drill Pipe	Non-Stainless Steel (Carbon Steel/Alloy Steel)	>168.3	4%	0%

Note: This is the most commonly used drill pipe code for oil and gas drilling. Information such as outer diameter, material, and processing method must be provided during declaration.

2. Drill Pipes for Geological Exploration

HS Code	Commodity Name	Key Characteristics	Import MFN Rate	Export Tax Rebate Rate
7304512000	Seamless geological drill pipes and casings made of cold-drawn or cold-rolled alloy steel	Cold-drawn/cold-rolled process, alloy steel, circular cross-section	4%	—

Note: Applicable to geological exploration, core drilling, etc. Examples include "Geological Drill Pipe" and "Drill Casing".

3. Drill Pipe Raw Materials/Semi-finished Products

HS Code	Commodity Name	Key Characteristics	Import MFN Rate	Export Tax Rebate Rate
7228800000	Other alloy steel hollow drill steel (including non-alloy steel)	Hollow drill steel, rod/bar shape, for further processing	7%	13%

Note: This is the upstream raw material form for drill pipes, such as hollow steel billets or drill pipe blanks without threads. Maximum external dimensions and maximum internal diameter must be additionally declared during the declaration.

HS Codes for Drill Pipe Parts and Accessories:

HS Code	Product Name	Applicable Products (Examples)	Description
8431431000	Parts for Oil or Gas Drilling Rigs	Drill pipe joints, drill collars, angular drill pipe stop valves, adapters, stabilizers, short sections, etc.	This is a classification for drilling rig-specific parts, covering a large number of drill pipe accessories.
8431432000	Other Drilling Rig Parts	Wireline drill pipes, wireline coring assemblies, coring drill pipes, weighted drill pipes, furnace dismantling machine drill pipes, etc.	Applicable to non-petroleum drilling equipment parts, such as geological exploration and engineering drilling.

Declaration Element Explanation: 

The declaration elements differ for different HS codes. When declaring customs, you must truthfully fill in the information according to the code requirements:

7304 Series (Drill Pipe) Declaration Elements:

● Specifications (outer diameter of the pipe)
● Application (boiler use, oil or gas drilling, etc.)
● Shape (pipe, hollow profile)
● Material (iron, non-alloy steel, stainless steel, alloy steel)
● Processing Method (cold drawing, cold rolling, hot rolling, etc.)
● Type (seamless pipe)

7228800000 (Hollow Drill Steel) Declaration Elements:

● Application (applicable location or downstream products)
● Shape Shape (strips, rods, angle bars, profiles, special-shaped profiles)
● Material (high-speed steel, silicon manganese steel, etc.)
● Processing method (hot rolling, hot drawing, hot extrusion, cold forming, cold working)
● Composition (iron, carbon, alloy element content)
● Steel grade
● Hollow drill steel requires additional declaration of maximum external dimensions and maximum internal diameter.

8431 Series (Parts) Declaration Elements:

● Application (applicable to XX brand XX machine or universally applicable to XX machine, etc.)
● Brand (Chinese or foreign language name)
● Model

Used Drill Pipe Customs Declaration Tips:

The HS code classification principle for used drill pipes is completely consistent with that for new products. Select the corresponding code according to the material and application. However, please note the following when declaring:

1. Product Name Labeling: Clearly indicate "used" or "second-hand" in the product name (e.g., "used oil drill pipe").
2. Accurate Declaration: It is recommended to provide supplementary information such as remaining wall thickness, wear degree, and inspection report.

3. Regulatory Requirements: Some used electromechanical products may be subject to import license management; it is recommended to confirm in advance.
