HS Code Detail
851770 Chapter 85 · Electronics Parts for telephones and smartphones
Six-digit subheading in Electronics, chapter 85 of the Harmonized System, carried for classification and search with no destination rates held against it.
Anatomy of 851770
A declaration is made against a longer local code beginning 851770. The first six digits are the same in every country that uses the Harmonized System; the trailing digits are national.
What this code covers
This code is no longer in the Harmonized System
Subheading 8517.70 was withdrawn in the 2022 edition. It is not in the UK Trade Tariff and the United States Harmonized Tariff Schedule, checked 2026-09-01.
It was replaced by more than one subheading, so there is no single code to send you to. What those two tariffs carry in its place today:
8517.718517.79
Which one applies to a particular product is a classification decision and this page does not make it for you. Any duty figures below are kept for reference and are not a rate you can declare against.

- Replacement screens, housings, antennas, line cards and transceiver modules for heading 8517 apparatus
What's specifically excluded
These look similar but belong under a different code:
Commonly confused with
850760: Replacement phone batteries
A lithium ion cell or pack is classified in 8507.60 by what it is, not as a telephone part, because batteries are named by their own heading. This is the single most frequent error in phone spares consignments and the codes are not interchangeable.
851830: Headsets and earphones
An earphone supplied in a handset box is still a headphone of 8518.30 when shipped separately as a spare, because it is an article named elsewhere rather than a part peculiar to a telephone.
Classification & cost note
Parts of heading 8517 apparatus are a large and growing trade on the back of the repair market, and the classification discipline is the same one that governs parts everywhere in Section XVI: an article named by its own heading goes to that heading, and only what is not otherwise named comes to rest as a part. That is why batteries, headphones and power adapters keep leaving this code even though they arrive in the same carton as things that stay. Repair businesses are exposed here in a way that manufacturers are not, because a mixed spares shipment can require half a dozen codes while the supplier's invoice describes everything as phone parts. The second issue is valuation rather than classification: parts bought at a discount for warranty use still have to be valued for customs on a defensible basis, and a nominal or free of charge invoice is not one.
Typical products: Replacement smartphone display assemblies · Handset back covers and frames · Router antennas and SFP transceiver modules · Charging port and flex cable assemblies
What the notes to section XVI say
Chapter 85 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 85 are quoted whole on the chapter 85 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 8517 by number.
Note 2 to section XVI
However, parts which are equally suitable for use principally with the goods of heading 8517 and 8525 to 8528 are to be classified in heading 8517, and parts which are suitable for use solely or principally with the goods of heading 8524 are to be classified in heading 8529;
What the nomenclature says about heading 8517
851770 is a subheading of 8517, telephone sets, including smartphones and other telephones for cellular networks or for other wireless networks; other apparatus for the transmission or reception of voice, images or other data, including apparatus for communication in a wired or wireless network (such as a local or wide area network), other than transmission or reception apparatus of heading 8443 , 8525 , 8527 or 8528 , and this site holds 3 other codes under the same heading, which every rule below governs equally.
One numbered note to chapter 85 takes heading 8517 as its own subject, and it is quoted below in full, as published.
Note 5 to chapter 85
For the purposes of heading 8517, the term "smartphones” means telephones for cellular networks, equipped with a mobile operating system designed to perform the functions of an automatic data processing machine such as downloading and running multiple applications simultaneously, including third-party applications, and whether or not integrating other features such as digital cameras and navigational aid systems.
Read from the notes to chapter 85 published in the UK Trade Tariff by HM Revenue and Customs, at https://www.trade-tariff.service.gov.uk/api/v2/chapters/85, with the heading title from https://www.trade-tariff.service.gov.uk/api/v2/headings/8517, on 2026-09-07, with the whole layer and the reason a heading note is a chapter note set out on the chapter 85 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 851770
Is HS code 8517.70 still valid?
No. The 2022 edition of the Harmonized System withdrew it, and neither of the two tariffs this site reads carried it when they were checked on 2026-09-01. The panel at the top of this page names the 2 subheadings that took its place and says what the duty figures below are still good for.
Is a replacement phone battery classified as a phone part?
No. Lithium ion cells and packs are classified in heading 8507 by what they are. Batteries are named by their own heading, so they never fall to be treated as parts of the device they power.
Can a repair shipment be declared on a single parts code?
Rarely. Screens and housings are parts of 8517.70, but batteries, earphones and chargers each take their own heading, so a mixed spares consignment normally needs several lines however uniformly the invoice describes it.
