Galvanization involves coating iron or steel with zinc to prevent rusting. While this treatment extends the life of pipes, it also alters their surface texture. The roughness created by the galvanization process can increase the friction factor compared to smooth-walled pipes. This increase implies greater energy requirements for pumping fluids through galvanized pipes, particularly in systems that rely on water or other low-viscosity fluids.

The HS Code for galvanized iron wire typically falls under Category 7 (Wire and Articles of Wire) in the international classification system. More specifically, it can be classified under HS Code 7217, which generally pertains to wire of iron or non-alloy steel, excluding stranded wire. The precise subheading may vary depending on the specific characteristics of the wire, such as its gauge, type of coating, and intended use.
