HS chapter 73: Articles of iron or steel
Section XV — Base metals and articles of base metal
Goods classified under this chapter include iron or steel articles such as pipes, fittings, and containers. For example, if you're importing seamless steel pipes for construction, you'll need to navigate this chapter to find the correct HS-4 code.
To determine the appropriate HS-4 code, start by identifying the specific product type. For instance, if you're dealing with iron or steel tubes, you'll look at headings like 7304 for seamless tubes or 7305 for those with a diameter over 406.4mm. Pay attention to the product's form and intended use.
Next, drill down to HS-6 codes by examining the notes and subheadings. For example, if you have a product that fits under 7308 (structures of iron or steel), you may need to consider additional specifications to ensure correct classification. Confusion often arises between similar headings, so check for specific details like dimensions and intended application.
Finally, consult national tariff schedules for any additional digits that may apply in your country. If you're uncertain about classification, reaching out to a customs broker or checking for prior rulings can provide clarity on the correct code to use.
