In international trade, correctly using the HS Code (Harmonized System Code) to classify mild steel pipes is crucial. This not only affects customs clearance efficiency but also directly relates to tariff rates, regulatory requirements, and whether additional certifications (such as certificates of origin, quality inspection certificates, and commodity inspection certificates) are needed.

According to the World Customs Organization (WCO), the HS code of steel pipes is mainly determined by the following factors:
Seamless steel pipe, welded steel pipe.
Round, square (SHS steel), rectangular (RHS steel).
Iron, carbon steel, alloy steel, stainless steel.
Structural use, fluid transportation, bolts/pipe fittings, etc.
The HS code for imported mild steel pipes is used to classify products in international trade, ensuring smooth customs clearance and accurate tax calculation.
Below are the most commonly used HS codes for imported mild steel pipes in international trade.
|

Error Type |
Impact |
|
Incorrectly declaring welded pipe as seamless pipe |
Large tariff difference, easily subject to inspection/tax payment |
|
Incorrectly classifying structural components as steel pipe |
Leads to coding mismatch and risk of duplicate declaration |
|
Incorrectly classifying pipe fittings (7307) as 7306 welded pipe |
Easily questioned by customs, delaying clearance |
|
Inconsistent HS codes between different countries |
Inconsistent codes between the exporting and destination countries may lead to goods being detained |
The HS code for mild steel pipes is mainly determined based on the manufacturing method (seamless/welded), product shape (round/square/rectangular), and whether it is a pipe fitting. Commonly used HS codes for imports include 7304 (seamless pipe), 7306 (welded pipe), and 7307 (pipe fitting); common export codes include 7306, 7307, and 7308.
