Tariff codes, also known as Harmonized System (HS) codes, are used by customs authorities to classify products and determine the appropriate duties and taxes. When importing galvanized steel wire rope, using the correct tariff code is crucial for smooth customs clearance and avoiding potential delays or penalties. An accurate tariff code ensures that your import complies with regulations and avoids misclassification, which can lead to costly mistakes or shipment delays.
1 Accurate Tariff Codes for Importing Steel Wire Rope Matters
Using the correct tariff code when importing steel wire rope directly impacts the cost and efficiency of your shipment. An incorrect HS code can result in paying the wrong duties—either overpaying, which cuts into your margins, or underpaying, which could lead to hefty fines, penalties, or customs audits. Misclassification can also delay the customs clearance process, causing disruptions in your supply chain and delaying your project timelines.
Furthermore, the wrong code might trigger additional regulatory requirements, inspections, or even rejections at customs, adding unnecessary complications. By ensuring you use the right tariff code, you streamline the customs process, avoid costly mistakes, and ensure compliance with international trade laws—saving both time and money in the long run.
2 Introduction to Tariff Codes (HS code)
A tariff code, or Harmonized System code (HS code), is a standardized numerical code used to classify commodities. The HS code system is globally standardized by the World Customs Organization (WCO), Each HS code is structured into categories that describe the product’s material, function, and use.
Each two digits of the HS code represents a classification. The first two digits represent the largest classification.
A typical HS code is made up of 6 digits that define a specific category, with additional digits added by individual countries for more detailed classification. In other words, the first six digits of the HS code for the same product are consistent across all countries, while different countries may extend the code to eight or ten digits based on their own requirements.
For example, the HS code for steel wire rope starts with 731210 worldwide. In China, all steel wire ropes are classified under the code 73121000, with no further distinctions.
In Vietnam, the code may be extended to eight digits to account for specific features such as coating or diameter, resulting in codes like 73121099 for “other.”

In the United States, the HS code system is even more detailed, with 22 different codes reflecting various specifications such as diameter and use. For instance, 7312109030 denotes “other-galvanized: with a diameter not exceeding 9.5mm.”

3 Steel Wire Rope Tariff Codes in Different Countries
Steel wire rope falls under the HS code 731210 globally, but different countries expand this code to meet their specific trade requirements. Below are some examples of the HS codes for galvanized steel wire rope with a diameter smaller than 6mm in various countries for reference.
United States: When looking up US tariffs, you may come across HTS and Schedule B. They are different systems, HTS is for imports and Schedule B is for exports. You can find more information on the United States International Trade Commission.
7312109030 — other — galvanized — with a diameter not exceeding 9.5mm
Vietnam: you can find detailed tariff code information on the Vietnam Customs Official Website.

European Union: The HS codes and tariffs are the same for all EU member states. It’s just that the VAT levied by each country is different. More information please find the EU official website.
7312106591 — plated or coated with zinc — with not more than 18 wires, of non-alloy steel, containing by weight 0,6% or more of carbon, excluding galvanized(but not with any further coating material) seven wire strands in which the diameter of the central wire is identical or less than 3% greater than the diameter of any of the 6 other wires.
