8526.91 Radio navigational aid apparatus
A full HS code. These six digits are what goes on a customs declaration, and they mean the same thing in every country that uses the Harmonized System.
Section XVI, Machinery & Electrical — machinery, mechanical appliances, electrical and electronic equipment.
- 85 Chapter Electrical machinery and equipment and parts thereof; sound recorders and reproducers; television image and sound recorders and reproducers, parts and accessories of such articles
- 26 Heading Radar apparatus, radio navigational aid apparatus and radio remote control apparatus
- 91 Subheading Radio navigational aid apparatus
Chapter 85 covers electrical machinery and equipment and parts thereof; sound recorders and reproducers; television image and sound recorders and reproducers, parts and accessories of such articles: motors, generators, batteries, telephones, semiconductors and most consumer electronics. Together with chapter 84 it makes up Section XVI, the machinery and electronics backbone of modern manufacturing trade. Classification tip: Multi-function electronics (a phone that's also a camera and a computer) are classified by their principal function under the General Rules of Interpretation, which is often the single most disputed classification question in this chapter.

The wording above is the Harmonized System nomenclature as published by the World Customs Organization, HS 2022 edition. It is a classification reference, not a tariff: it carries no duty rates, and it stops at six digits — the importing country adds its own beyond that.
Classification is decided by the General Rules of Interpretation and the section and chapter notes, and it is the importing country’s customs authority that makes it binding.
Shipping goods under 8526.91? A customs hold shows up as a milestone that stops moving — follow the container or the air waybill from departure to delivery.

8526.91 covers radio navigational aid apparatus. It sits under heading 85.26 (radar apparatus, radio navigational aid apparatus and radio remote control apparatus) in chapter 85, Section XVI of the Harmonized System.
It is the international part of it. Six digits are the same in every country that applies the Harmonized System; the importing country then extends them to eight or ten for its own tariff and statistics. Declare 8526.91 plus whatever national digits the destination’s tariff schedule adds to it.
The General Rules of Interpretation, read together with the notes to Section XVI and to chapter 85. A description that reads right is not enough on its own — the notes routinely pull goods out of the chapter they obviously belong to and put them somewhere else. Where duty or licensing turns on the answer, ask the importing country’s customs authority for a binding ruling.
A wrong or missing code is one of the common reasons customs holds a container, and a hold shows up as a milestone that stops moving. Watch for it in the container tracking app, on the air waybill in the air cargo tracker, or through the tracking API.
