HS Code Detail
847330 Chapter 84 · Machinery Parts and accessories for computers
Six-digit subheading in Machinery, chapter 84 of the Harmonized System, priced here for 6 destination markets.
Anatomy of 847330
You will declare against a longer local code that begins 847330: ten digits in the United States and the United Kingdom, eight in the European Union, and the first six the same everywhere. Which trailing digits apply is what a rate can differ on, though on this subheading all 6 destinations below charge the same, 0%.

What that costs: 847330 into Portugal
An illustrative consignment of 847330 invoiced at EUR 2,000.00, priced in EUR because a threshold is set in the destination's currency and nothing here is converted.
| Goods value on the invoice | EUR 2,000.00 |
| International freight | EUR 120.00 |
| Cargo insurance | EUR 30.00 |
| Value the duty is charged on, CIF basis | EUR 2,150.00 |
| Duty at 0% | EUR 0.00 |
| Portugal tax at 23%, charged on the value plus the duty | EUR 494.50 |
| Total, before commercial charges | EUR 2,644.50 |
And if the consignment were small
Portugal relieves nothing: the relief was abolished, so the duty above is charged whatever the consignment is worth. A smaller shipment pays less because the value is lower, not because a threshold spared it.
Selling rather than buying? EUR 2,644.50 is what your buyer in Portugal pays to take delivery of this consignment, yours to pay if you quote DDP and theirs if you quote DAP: Exporting to Portugal sets out who collects it and what your invoice has to say.
An illustration, not a quotation: broker fees, handling and any trade remedy on the origin sit outside it. Price 847330 on your own numbers in the duty calculator.

Re-check first: Every United States line is free, printed circuit assemblies included. The classification risk runs the other way here: a part that is itself a complete machine is classified as that machine and not under this subheading.
What falls under 847330
- Parts and accessories of the automatic data processing machines of heading 8471
- Motherboards, graphics cards, sound cards, internal power supplies, laptop chargers and computer housings
What's specifically excluded
These look similar but belong under a different code:
Commonly confused with
854232: Memory chips
A bare integrated circuit is classified in 8542 by what it is, while a memory module assembled onto a printed circuit board for a computer is a part of an ADP machine. The board is what moves the goods from 8542 to 8473.30, and RAM modules are the everyday example.
850440: Chargers and power adapters
An external power supply is a static converter and is frequently classified in 8504.40 rather than as a computer part, because it converts mains current rather than performing a data processing function. Internal PSUs built into a chassis are treated differently from external bricks.
Classification & cost note
Parts classification is governed by the section notes rather than by intuition, and the sequence matters: a part that is itself named by a heading in Chapter 84 or 85 goes to that heading, and only what is left over is a part of an ADP machine. That is why a bare chip goes to 8542 and a memory module on a board comes here, and why an external power adapter is often a static converter rather than a computer part. The rule that catches importers hardest is that a part must be suitable for use principally with machines of heading 8471 to sit in 8473.30 at all. A fan, a screw or a generic cable is not, and takes its own material or function code. Spares consignments are therefore rarely a single line however uniform they look on a packing list, and a spares business that declares everything as computer parts is carrying an unquantified exposure.
Typical products: Motherboards and expansion cards · Discrete graphics cards · RAM modules on printed circuit boards · Laptop replacement housings, hinges and internal power supplies
What the notes to section XVI say
Chapter 84 sits in section XVI, machinery and mechanical appliances; electrical equipment; parts thereof, sound recorders and reproducers, television image and sound recorders and reproducers, and parts and accessories of such articles, where a section note governs every chapter in the section and applies before the heading notes below; the 6 reaching chapter 84 are quoted whole on the chapter 84 page, read from https://www.trade-tariff.service.gov.uk/api/v2/sections/16 on 2026-09-08, and this is the one that names heading 8473 by number.
Note 2 to section XVI
Parts which are goods included in any of the headings of Chapter 84 or 85 (other than heading 8409, 8431, 8448, 8466, 8473, 8487, 8503, 8522, 8529, 8538 and 8548) are in all cases to be classified in their respective headings.
b. Other parts, if suitable for use solely or principally with a particular kind of machine, or with a number of machines of the same heading (including a machine of heading 8479 or 8543) are to be classified with the machines of that kind or in heading 8409, 8431, 8448, 8466, 8473, 8503, 8522, 8529 or 8538 as appropriate.
c. All other parts are to be classified in heading 8409, 8431, 8448, 8466, 8473, 8503, 8522, 8529 or 8538 as appropriate or, failing that, in heading 8487 or 8548.
What the nomenclature says about heading 8473
847330 is a subheading of 8473, parts and accessories (other than covers, carrying cases and the like) suitable for use solely or principally with machines of headings 8470 to 8472 , and it is the only code this site holds under that heading.
No numbered note to chapter 84 takes heading 8473 as its subject, which is what the published notes say rather than a gap on this page: the heading is defined by its own wording above and by the note to the chapter, quoted in full on the chapter 84 page.
Read from the notes to chapter 84 published in the UK Trade Tariff by HM Revenue and Customs, at https://www.trade-tariff.service.gov.uk/api/v2/chapters/84, with the heading title from https://www.trade-tariff.service.gov.uk/api/v2/headings/8473, on 2026-09-07, with the whole layer and the reason a heading note is a chapter note set out on the chapter 84 page. These notes are part of the international text of the Harmonized System, so the rule is the same whichever destination a shipment is going to, and it decides classification and never a rate.
Questions about 847330
Are RAM modules classified as integrated circuits?
No. A bare chip is an integrated circuit of 8542, but once memory is mounted on a printed circuit board as a module for a computer it becomes a part of an ADP machine under 8473.30. Assembly onto the board is what moves it.
Can I declare a whole spares shipment as computer parts?
Usually not. Only parts suitable for use principally with machines of heading 8471 belong here. Generic fasteners, fans and cables take their own codes, so a mixed spares consignment normally needs several lines.
