HS Code 8507.90 – Electric accumulators; parts n.e.c. in heading no. 8507
HS code 8507.90 is the 6-digit subheading for electric accumulators, parts n.e.c. in heading no. 8507. It is used for lithium-ion battery separators, lead-acid battery plates, nickel-metal hydride battery casings, battery terminals and battery cell connectors.
What HS 8507.90 covers
This HS code covers the essential components and parts of electric accumulators (rechargeable batteries) that are not specifically classified elsewhere within heading 8507. This includes items like battery cases, separators, terminals, covers, and other structural or functional parts crucial for assembling or repairing various types of rechargeable batteries, from lead-acid to lithium-ion. International trade in these parts is significant, driven by global manufacturing hubs for electronics, electric vehicles, and renewable energy storage systems. Major importers are often countries with large battery assembly plants or those heavily invested in EV production, while exporters are typically nations with advanced materials science and manufacturing capabilities. Key things to know include the increasing demand for advanced battery components due to the EV revolution and the growing focus on sustainable sourcing and recycling of battery materials. The trade flow reflects the complex global supply chains for energy storage solutions, with a constant push for lighter, more efficient, and longer-lasting components.

Codes often confused with 8507.90
Common mistake. This code can be confused with complete batteries (e.g., 850760 for lithium-ion) or raw battery materials (e.g., chemicals in Chapter 28 or 38), as it specifically covers parts of accumulators, not the finished product or basic raw materials.
Top exporters and importers of HS code 850790, 2025
In 2025, the largest exporter of HS code 850790 in UN Comtrade data was China, with 32% of world exports; the largest importer in UN Comtrade data was the United States, with 29% of world imports. Countries that did not report 2025 data are estimated from partner records, which can understate them.

How these figures are built
109 countries reported 2025 trade to UN Comtrade in HS 2022, and their own totals are used. Countries that did not report are estimated from what other countries recorded trading with them. Those estimates miss trade with other non-reporting countries, so they can be low, and a non-reporting country can rank higher than shown or be missing from the list. World totals add both and leave out trade between two non-reporting countries. Figures are in current US dollars; reported imports are mostly valued CIF and exports FOB, and exports include re-exports. The UN Comtrade links show the underlying records; they can also list a few reporters left out here (regional groups and older HS editions).
