HS code for Furnace lining paste: 3801.30

Carbonaceous pastes, for electrodes and similar pastes for furnace linings.

Classification of furnace lining paste under HS 3801.30

The classification of furnace lining paste under HS code 3801.30 is determined by its chemical composition and specific industrial application in metallurgy. This code specifically addresses carbonaceous pastes designed for electrodes and similar pastes used for furnace linings. These materials are typically composed of a mixture of carbonaceous aggregates, such as anthracite, coke, or graphite, combined with a binder like coal tar pitch or synthetic resins. Under the General Rules of Interpretation (GRI), specifically GRI 1, the product is classified based on the heading text which explicitly mentions \"carbonaceous pastes for electrodes and similar pastes for furnace linings.\" The classification falls within Chapter 38, which encompasses miscellaneous chemical products, rather than Chapter 68 (stone and mineral products) because the carbonaceous nature and the specific preparation as a paste for metallurgical applications align more closely with the definitions provided in the Explanatory Notes for heading 38.01. This heading covers artificial graphite, colloidal or semi-colloidal graphite, and preparations based on graphite or other carbon in the form of pastes, blocks, plates, or other semi-manufactures.

Covers
  • Carbon-based ramming pastes
  • Electrode pastes (Soderberg paste)
  • Cold ramming pastes for furnace hearths
  • Carbonaceous jointing compounds for furnace blocks
  • Graphite-based furnace lining materials
Also under 3801.30
  • RHI Magnesita carbon paste
  • Imerys graphite electrode paste
  • Elkem Carbon Söderberg paste
  • Tokai Carbon electrode paste
  • GrafTech furnace lining paste

Codes often confused with 3801.30

Common mistake. A frequent point of confusion involves HS code 3816.00, which covers refractory cements, mortars, and concretes. While both are used for furnace linings, 3816.00 is reserved for non-carbonaceous (mineral-based) refractory materials. Another common error is using 2713.11 or 2713.12 for petroleum coke; however, these codes refer to the raw material rather than the prepared paste. Additionally, if the material is already shaped into bricks, it may be misclassified under 6810 or 6902, but the paste form remains strictly under 3801.30.

Top exporters and importers of HS 380130 (the code used for furnace lining paste), 2025

In 2025, the largest exporter of HS 380130 (the code used for furnace lining paste) in UN Comtrade data was China, with 54% of world exports; the largest importer in UN Comtrade data was Indonesia, with 41% 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).

Questions about furnace lining paste

What is the HS code for Furnace lining paste?

The HS code for Furnace lining paste is 380130 (Carbonaceous pastes; for electrodes and similar pastes for furnace linings). The primary HS code for furnace lining paste is 3801.30, which covers carbonaceous pastes for electrodes and furnace linings.

How do I classify Furnace lining paste for customs?

Furnace lining paste is classified under HS code 380130 — Carbonaceous pastes; for electrodes and similar pastes for furnace linings. This is a 6-digit subheading level code.

Is electrode paste the same as furnace lining paste?

While they share the same HS code (3801.30), they differ in their specific formulation and binder content to suit their respective roles in electrical conductivity or thermal insulation.

Which countries are the top exporters of furnace lining paste (HS 380130)?

In 2025, the top exporters of HS 380130 (the code used for furnace lining paste) in UN Comtrade data were China ($237M, 54% of world exports), Norway ($71M) and Germany ($41M). World exports came to about $441M, adding countries' reported figures and partner-based estimates for those that did not report (UN Comtrade data). Countries that did not report 2025 data are estimated from partner records, which can understate them.
