HS code 7407 for copper bars, rods and profiles

What heading 7407 covers

Heading 7407 sits in chapter 74 of the Harmonised System and covers copper bars, rods and profiles. It is a mill product heading. The goods are solid copper shapes with a constant cross-section, produced by rolling, extrusion, drawing or forging, and they have not been worked into a finished article.

The heading is broad in material terms. It covers refined copper and copper alloys, including the brass and bronze grades used for electrical parts. National tariff schedules then split the heading by alloy, by cross-section and sometimes by temper or surface condition.

The important point for a buyer is that 7407 describes the shape, not the function. A copper bar does not become an electrical part because it is intended for a switchboard. It becomes an article when it is processed beyond the definitions in the chapter.

Bar, rod and profile are defined terms

The chapter notes define the three product forms. A bar or rod is a solid product with a uniform cross-section, supplied straight or in coils. The difference between a bar and a rod is usually the form and the way it is supplied rather than the metallurgy. A profile is also a solid product with a uniform cross-section, but its cross-section is not a simple circle, rectangle or other shape that fits the bar definition.

In practice, a rectangular copper busbar is a bar. A round copper conductor is a rod or wire depending on diameter and form. An extruded shape with a custom cross-section, such as a channel or a finned section, is a profile.

These definitions matter because a drawing may call a part a bar when the customs definition points elsewhere. Use the dimensions and the cross-section, not the drawing title.

What 7407 does not cover

Copper wire is classified in heading 7408. The distinction between wire and rod turns on the product definition and the dimensions in the chapter notes, not on what the supplier calls it. A drawn round product below the relevant threshold is likely wire, which moves the code and often the duty treatment.

Copper plates, sheets and strip are in heading 7409. Copper tubes and pipes are in 7411. Stranded copper wire, cables and plaited bands are in 7413. Insulated electrical cable is in chapter 85, not chapter 74.

Finished copper articles fall in 7419, the residual heading for other articles of copper. That includes many brackets, terminals, washers and fabricated parts. A copper part that has been machined, drilled or assembled may leave 7407 even though the input was a bar.

The busbar question

Busbars are the most common source of confusion. A straight length of rectangular copper bar sold as stock is a 7407 product. The same bar cut to length, punched with mounting holes, bent and tin plated may still be classified as a bar in some tariff administrations, or as an article of copper in others, depending on how far the processing goes and how the destination applies its national practice.

The presence of holes, bends, threads or a specific terminal shape is the usual test. Simple cutting and deburring is usually not enough to make an article. Drilling, bending, threading or assembling a termination starts to look like fabrication. Insulation changes the analysis again: an insulated busbar may fall in chapter 85 as insulated conductor or apparatus.

This is exactly the kind of question that should not be settled by analogy. Ask for a written classification or an advance ruling, and keep the drawing that was assessed with the entry. A code that was right for a stock bar may be wrong for the finished busbar.

How processing changes the classification

Think of a ladder from the mill product to the finished part. At the bottom is the cast or extruded shape. A step up is cutting to length and facing the ends. Further up are holes, bends, threads and surface treatment. At the top is an assembly with insulators, fasteners or a moulded housing.

Each step can change the legal character of the goods. The chapter notes and the explanatory notes describe when a bar remains a bar and when it becomes an article. National practice can differ at the margins, particularly for busbars that are drilled and bent but not assembled.

Plating is usually not enough on its own to move a bar out of 7407, but it can change the national subheading and may add a processing cost that affects the customs value. Assembly with another component is a stronger signal that the goods are now an article or a part of apparatus.

The order of operations matters as well. A bar that is bent before plating and a bar that is plated before bending can have different residual stresses and different dimensional results, but the tariff question is about the state of the goods at import. Describe the final state and the operations that produced it, in sequence, so the broker can see how far the goods have moved from the mill product.

Alloy and national digits

The six digit heading is only the start. National schedules split 7407 by copper alloy, such as refined copper, copper zinc alloys, copper tin alloys and copper nickel alloys. Some split further by cross-section, by whether the product is in coils, or by temper.

That matters because two busbars with the same dimensions but different alloys can land on different tariff lines. A C11000 tough pitch copper bar and a brass bar are not the same product for tariff purposes, even if both are called copper bar on the purchase order.

The material certificate is the evidence. It should state the alloy designation, the temper and the dimensions. If the certificate is missing or the alloy is described only by a trade name, the classification record is weak.

Temper is easy to overlook because it does not change the shape. A hard drawn bar and a soft annealed bar can have the same cross-section and the same alloy, yet they behave differently in forming and may sit on different national lines. Ask for the temper on the certificate and quote it in the entry description.

A classification record for a copper product

Build a short record for every repeat copper part. It should let a broker or an auditor follow the reasoning without calling the supplier. Update it when the drawing, the alloy or the processing route changes.

• Product form: bar, rod, profile, wire, strip, tube or article
• Cross-section drawing with dimensions and tolerances
• Alloy designation and temper from the mill certificate
• Processing steps after the mill, including cutting, drilling, bending and plating
• Whether the part is insulated or assembled with other components
• Destination code and the national digits applied
• The written ruling or broker rationale, with a review date

Confirm before you commit

The duty rate for a 7407 line depends on the destination tariff, the origin of the goods and any measures in force. It should not be taken from a blog, a supplier invoice or a previous shipment without checking the current tariff.

For a new programme, ask the broker to confirm the full destination code and the rate in writing. For a high value or repeat part, consider an advance ruling. The cost of the ruling is small compared with a correction across a year of shipments.
