HS code 7616 for aluminium articles

What heading 7616 covers

Heading 7616 covers other articles of aluminium. Like 7326 for steel, it is a residual heading. It applies after the specific aluminium headings have been checked: unwrought metal, bars and profiles, wire, plate, sheet, strip, foil, tube and structures.

The heading covers a wide range of finished aluminium items, including brackets, clamps, covers, cases, ladders and many machined or fabricated components. The article must be made of aluminium and must not be more specifically covered elsewhere.

The residual logic is the same as in chapter 73. A specific heading wins over a general one. A part dedicated to a machine or an electrical apparatus can leave chapter 76 altogether.

A common error is to use 7616 for any aluminium part that has been machined. Machining a pocket into a billet does not automatically make the result an article in 7616 if a more specific heading covers it, and it does not automatically move a profile out of 7604 if the part is still sold as a length of profile. The product form at import is the starting point.

From metal to article

Chapter 76 is arranged by product form. Unwrought aluminium is in 7601. Bars, rods and profiles are in 7604. Wire is in 7605. Plates, sheets and strip are in 7606. Foil is in 7607. Tubes and pipes are in 7608. Each heading covers a mill product with a defined form.

An article in 7616 is further down the line. It has been cut, formed, machined, welded or assembled into something whose identity is the finished item rather than the stock shape. A length of extruded profile is a 7604 product. The same profile cut, drilled and fitted with end caps may be a 7616 article.

The transition is not always sharp. Cutting to length is usually not enough to make an article. Drilling, bending, machining a pocket or welding on a bracket is stronger evidence. The destination tariff and the chapter notes decide where the line falls.

A useful habit is to describe the goods in the state in which they are packed. If the box contains a two metre length, it is a profile. If it contains a finished bracket with a part number, it is an article. The packing list and the drawing should tell the same story, because the broker will read both.

Extrusion or finished article

Extrusion is the most common route for aluminium parts in electrical equipment. The press produces a long profile with a constant cross-section. That profile is a 7604 product while it remains a profile.

Cutting the extrusion to length and deburring the ends usually leaves it in 7604. Cutting, machining pockets, drilling mounting holes, tapping threads and anodising starts to look like a finished article. If the part is then assembled with other components, the assembly may have its own heading.

The drawing is the evidence. A drawing that specifies a profile number and a cut length describes a mill product. A drawing that specifies holes, threads, a finish and a part number describes an article. Send the broker the drawing that matches what is actually shipped.

The heat sink question

Aluminium heat sinks are a frequent classification question. A heat sink sold as a standard extruded profile is usually a 7604 product. A heat sink that is cut, drilled, machined and finished as a catalogue part is more likely to be a 7616 article.

The answer can change when the heat sink is dedicated to a specific machine or electronic assembly. A part that is designed only for a particular device may be classified as a part of that device, which can move it to chapter 84 or 85. A general purpose heat sink sold to many customers is more likely to stay in chapter 76.

There is no single answer that covers every heat sink. The function, the dedication and the presentation all matter. For a repeat programme, get the classification in writing and keep the drawing and the parent assembly reference.

Presentation also matters. A heat sink packed as a spare part for a named machine is easier to treat as a part than the same heat sink packed in bulk for a distributor. Describe the pack and the sales route on the record, because they support the dedication argument.

Cast, wrought and the subheading

At six digits, 7616 has a subheading for nails, screws, rivets, washers and similar articles, and a residual subheading for other articles. National schedules then split the residual group by product type or by alloy.

The production route matters. A die cast housing, a machined billet part and a fabricated weldment are different products even when they perform the same function. The process route should be on the classification record because it affects the national line and the value build up.

Alloy also matters. The 6000 series, the 5000 series and the casting alloys have different properties and different national breakdowns in some markets. The mill certificate or the casting specification is the evidence.

Temper is part of the description too. A T6 extrusion and an annealed extrusion can have different national lines, and the temper affects the strength and the machining behaviour. State it on the record.

Finish, assembly and value

Anodising, powder coating and painting are common on aluminium parts. They usually do not move the goods out of chapter 76, but they change the appearance, the corrosion performance and the customs value. The finish specification belongs with the classification record.

Assembly is a stronger signal. A heat sink with a fan, a bracket with a threaded insert, or a cover with a gasket is more than a single aluminium article. The assembly may be classified as a machine part or as an apparatus, depending on what it does.

Value also matters for the duty base. The customs value can include tooling, design work and assists supplied free of charge, not just the invoice price of the part. Keep the commercial documents consistent with the declared value.

A classification record for an aluminium part

The record should let a broker see the product form, the process route and the function without a call. Update it when the drawing or the finish changes.

Keep a photograph of the part as packed with the record. It is the fastest way to settle a question about whether a part is a profile or an article, and it avoids a long exchange about a drawing that neither side can open.

• Product form at import: profile, plate, tube or finished article
• Alloy and temper from the mill or casting certificate
• Process route: extruded, cast, machined, fabricated or assembled
• Finish: anodised, painted, powder coated or bare
• Whether the part is dedicated to a parent machine or assembly
• Destination code and the national digits applied
• The ruling or broker rationale, with a review date

Confirm the code and rate

The duty rate for a 7616 line depends on the destination tariff, the origin of the goods and any measures in force. A rate from an earlier shipment is not evidence of the current rate.

The destination tariff, a customs broker or a written ruling should confirm the code. For a high value or repeat part, an advance ruling removes the uncertainty from every shipment and gives the supplier a fixed basis for the invoice description.
