Product classification
HS code for Pulp making machine: 8439.10
Machinery, for making pulp of fibrous cellulosic material.
Classification of pulp making machine under HS 8439.10
HS code 8439.10 is designated for machinery used in the production of pulp from fibrous cellulosic materials, such as wood, cotton linters, or recycled paper. This classification falls under Chapter 84, which covers nuclear reactors, boilers, machinery, and mechanical appliances. Specifically, heading 8439 addresses machinery for making pulp of fibrous cellulosic material or for making or finishing paper or paperboard. The sub-heading 8439.10 is reserved for the initial stage of the papermaking process—the conversion of raw materials into pulp. This includes mechanical, chemical, or semi-chemical pulping equipment. Classification is based on the machine's primary function in the industrial sequence of paper production. The machinery must be specifically designed for the extraction of fibers from the raw material to create the pulp slurry. This classification remains consistent whether the machine is used in a large-scale industrial mill or a specialized recycling facility, provided the output is cellulosic pulp.

Codes often confused with 8439.10
Common mistake. Pulp making machinery is frequently confused with HS code 8439.20, which is dedicated to machinery for making paper or paperboard. While both are part of the same production line, 8439.10 is strictly for the creation of the pulp itself, whereas 8439.20 covers the machines that take that pulp and form it into sheets. Another common error is classifying wood-chipping machines under 8439.10. Wood chippers are generally classified under 8465.96 as machine tools for working wood. Only machines that perform the actual pulping (fiber separation) belong in 8439.10.
Top exporters and importers of HS 843910 (the code used for pulp making machine), 2025
In 2025, the largest exporter of HS 843910 (the code used for pulp making machine) in UN Comtrade data was China, with 34% of world exports; the largest importer in UN Comtrade data was Brazil, with 46% of world imports. Countries that did not report 2025 data are estimated from partner records, which can understate them.
Figures cover everything classified under HS 843910, not only pulp making machine.

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).
