Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If of cast iron construction
Material-specific classification applies to certain concrete pumps, but stock pumps of cast iron may qualify here instead.
If for use in non-cellulosic processes
Without the specific end-use for pulp/paperboard, it defaults to other parts of stock pumps.
If sold as part of a complete pulp preparation set
Machinery parts not elsewhere specified could apply if bundled with other pulp processing components.

Import Tips & Compliance
• Include manufacturer's declaration specifying compatibility with cellulosic pulp or paperboard machines to meet import requirements
• Check for proper labeling of wetted parts materials; acidic pulp environments require specific alloys to prevent premature failure
• Avoid common error of importing without proof of end-use, leading to higher general duty rates
