Chapter 73: Articles of iron or steel

Plain-language overview

Use HS-4 7318 when importing screws, bolts, nuts, and similar articles made of iron or steel. For example, if you're shipping threaded coach screws for furniture assembly, this heading applies. It encompasses various types of fasteners that are essential in construction and manufacturing.

Choosing the right HS-6 line under 7318 depends on the specific type of fastener. For instance, if your shipment includes threaded wood screws, you should classify them under 731812. However, if you have non-threaded rivets, you would use 731823 instead. Understanding these distinctions is crucial for accurate classification and compliance.

The boundary between 731815 and 731819 can be tricky. If your shipment contains threaded screws and bolts that aren’t specifically categorized elsewhere, you would select 731819. But if they come with their nuts or washers, 731815 is the right choice. Pay attention to packaging and included components to make the correct decision.
