8311.30.30.00 - Lead-tin solders

This HTS category, 8311.30.30.00, specifically covers lead-tin solders. These are essential consumable materials used in joining base metals, often in electronics manufacturing, plumbing, and automotive repair. The defining characteristic of this classification is the composition of the solder, which primarily consists of a blend of lead and tin, often with small amounts of other metals to modify its melting point and bonding characteristics.

At this level of the Harmonized Tariff Schedule, the primary distinction is between different types of coated rods and cored wire used for soldering. While sibling category 8311.30.60.00 encompasses "Other" coated rods and cored wire for flame soldering, this specific code is dedicated to the lead-tin alloy variety. This implies that if a soldering material is not primarily composed of lead and tin, it would likely fall under the "Other" category. The classification hinges on the specific metallic composition of the solder material itself.

As a leaf node in the HTS, 8311.30.30.00 does not have further subdivisions. Therefore, classification within this code is determined by confirming that the product is indeed a solder primarily made of lead and tin, and that it is presented in the form of coated rods or cored wire intended for soldering applications. The purpose of the material as a flux-cored or coated consumable for joining metals is paramount for correct classification.
