Antimonial Lead Ingot 10% Sb

Unwrought lead ingot alloyed with 10% antimony by weight, used primarily in battery manufacturing for improved hardness and corrosion resistance. This falls under tariff item 7801.91.00 because antimony is the principal other element by weight, as required by the subheading note for refined lead.

Battery-Grade Antimony Lead Pigs 8% Sb

Cast pig forms of unwrought lead alloy containing 8% antimony by weight, optimized for lead-acid battery grids. This product is classified under tariff item 7801.91.00 because antimony is the principal other element, enhancing grid strength, and the pigs are in unwrought form.

Corrosion-Resistant Lead-Antimony Slabs 11% Sb

Flat unwrought slabs of lead alloyed with 11% antimony for chemical plant linings and acid-resistant applications. These slabs are rough-cast and not further worked, so they qualify as unwrought lead under tariff item 7801.91.00, with antimony as the primary other element.

Hard Lead-Antimony Billets 12% Sb

Cylindrical unwrought billets of lead with 12% antimony, designed for cable sheathing and type metal production. The billets are cast directly and not further worked, so they fall under tariff item 7801.91.00 because antimony is the chief alloying element.

High-Purity Antimonial Lead T-Bar 13% Sb

T-shaped unwrought lead bars containing 13% antimony, favored for bearing alloys and precision casting. The T-shape is a result of the casting process, not subsequent working, so the product remains unwrought and is classified under tariff item 7801.91.00 with antimony as the key secondary element.

Solder-Grade Antimony Lead Anodes 9% Sb

Unwrought anode forms of lead with 9% antimony used in electroplating baths for durability. These cast shapes are intended for immersion without further working, so they are classified under tariff item 7801.91.00 because antimony predominates as the alloying element.

Type Metal Lead-Antimony Bars 15% Sb

Rectangular unwrought bars of lead with 15% antimony, traditional for printing type casting due to low shrinkage. The bars are cast directly and not further worked, so they fall under tariff item 7801.91.00 with antimony as the main alloy component.

Cable Sheathing Lead-Arsenic Alloy Ingots

Cable sheathing lead-arsenic alloy ingots are unwrought ingots of lead alloyed with arsenic for submarine power cable sheathing. With lead as the predominant metal and content below 99%, they fall under tariff item 7801.99.00.
