Chapter 73 covers articles of iron or steel, including seamless pipes, welded pipes, hollow profiles, pipe fittings, steel structures, articles of iron wire, etc. This chapter is based on iron and steel materials, manufactured through casting, forging, welding, machining, etc., but excludes mechanical appliances, vehicles, ships, etc. of iron or steel, which are classified in other chapters. Heading 7306 covers other tubes, pipes and hollow profiles of iron or steel, such as seamless pipes, welded pipes (not cast), riveted pipes, etc., as well as hollow profiles. However, it excludes cast iron pipes (7303), seamless pipes (7304), cold-drawn or cold-rolled pipes (7304), and pipes fitted with fittings (7307). The first 2 digits 73 represent articles of iron or steel; the 3rd-4th digits 06 represent other tubes, pipes and hollow profiles of iron or steel, including welded pipes; the 5th-6th digits 50 represent hot-rolled welded pipes, specifically welded pipes for oil or gas pipelines with an external diameter exceeding 406.4mm. Code 730650 is a six-digit subheading, which needs to be further detailed to 8-10 digits in customs declaration. This product is a hot-rolled welded pipe, which is a type of welded pipe and has not been cold-drawn or cold-rolled, so it is classified under 7306 rather than 7304 (seamless pipes) or 7305 (other welded pipes). At the same time, its hot-rolling process and welding forming method conform to the description of 730650, so it is classified under this code.

📝 Declaration Elements
Product Name: Declare the commodity name, which should be accurately described as hot-rolled welded pipe, and indicate the use such as oil pipeline. Material: Fill in the steel grade and chemical composition, such as Q235B, L245, etc. Specifications and Dimensions: Fill in outer diameter, wall thickness, length, etc., such as outer diameter 508mm, wall thickness 10mm. Processing Technology: Indicate hot rolling, welding (such as straight seam welding, spiral welding), etc. Use: Fill in the specific use, such as oil and gas transportation. Grade: Fill in the standard steel grade, such as API 5L X70. Standard: Fill in the executive standard, such as API 5L, GB/T 9711. Product Name: Hot-rolled welded pipe; Material: L245; Specifications: Outer diameter 508mm, wall thickness 10mm, length 12m; Processing Technology: Hot rolling, straight seam welding; Use: Oil and gas transportation; Grade: API 5L X70; Standard: API 5L. Misclassifying hot-rolled welded pipe as 7304 seamless pipe. Ignoring the outer diameter size, leading to incorrect subheading. Not specifying the welding method, affecting classification.
Product Name
Declare the commodity name, which should be accurately described as hot-rolled welded pipe, and indicate the use such as oil pipeline.
⚠️ Only writing steel pipe, without indicating hot-rolled and welded.

🎯 Classification Logic
Classification basis: 1. Material is iron or steel; 2. Processing technology is hot rolling and welding; 3. Use is for oil and gas pipelines; 4. Outer diameter size. According to HS notes, 7306 includes welded pipes, but must be distinguished from seamless pipes and cold-drawn pipes. 7304 Seamless pipes: Seamless pipes are made by piercing and rolling, without welds; welded pipes have welds, which can be distinguished by appearance or process. 7305 Other welded pipes: 7305 includes welded pipes with an outer diameter greater than 406.4mm, but 730650 specifically refers to hot-rolled welded pipes used for oil and gas. 7306 Other welded pipes: 7306 includes various welded pipes, but 730650 is hot-rolled welded pipe, which needs to be distinguished based on process and dimensions. 7307 Pipe fittings: 7307 is pipe fittings, such as flanges, joints, while 730650 is the pipe body itself. Confirm the material is iron or steel. Confirm the processing technology is hot-rolled welding. Confirm the use is for oil and gas. Confirm whether the outer diameter exceeds 406.4mm. Confirm whether it has been cold-drawn or cold-rolled.

What products is HS code 730650 applicable to? It is applicable to hot-rolled welded pipes with an outer diameter exceeding 406.4mm, mainly used for oil or gas pipelines. It must meet the conditions of hot rolling, welding, not cold-drawn, etc. How to distinguish 730650 from 7304? 7304 is seamless pipe, without welds; 730650 is welded pipe, with welds. They can be distinguished by visual inspection or process documents. What materials are required for declaration? Product name, material, specifications, processing technology, use, grade, standard, etc. are required. It is recommended to attach material certificates and process descriptions. If the outer diameter is less than 406.4mm, which code should it be classified under? It may be classified under other subheadings of 7306, such as 730630 (other welded pipes) or 730640 (stainless steel welded pipes), and needs to be further determined based on material and process. What is the difference between hot-rolled welded pipe and cold-drawn welded pipe? Hot rolling is carried out at high temperature, cold drawing at room temperature. Cold-drawn pipes have more precise dimensions and smoother surfaces, but are classified differently; cold-drawn pipes are usually classified under 7304. How to inquire about import tax rates? The latest tax rates can be queried through the website of the General Administration of Customs or the China Council for the Promotion of International Trade.
