Antimony Trioxide Powder Pellets
Pelletized antimony trioxide, a compound of antimony and oxygen, is presented in pellet form for use as a flame retardant additive in plastics. Although antimony trioxide is a chemical compound, the pellets are manufactured articles of antimony and are classified under 8110.90.00 as 'other' articles, provided they are not more specifically described elsewhere (e.g., as a prepared additive of Chapter 38). The pellets are not unwrought metal, waste, scrap, or powder.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If the pellets are actually powder agglomerates that break down to pass a 1 mm sieve
The definition of powders includes products where 90% or more by weight passes through a 1 mm mesh; if the pellets are not stable, they may be classified as powder.
If the product is a chemically defined compound presented in its ordinary form (e.g., powder, not pelletized)
Antimony trioxide is an inorganic chemical compound of Chapter 28; pelletizing may not remove it from that chapter if it remains a chemical product rather than an article.

Import Tips & Compliance
• Confirm the pellets are not classified as a prepared additive under Chapter 38 (e.g
• if they contain binders or other chemicals beyond pure antimony trioxide)
• Provide a technical datasheet showing the pellet dimensions and composition to support classification as an article of antimony
• Note that if the pellets are merely agglomerated powder, they may be considered 'powders' under 8110.20.00, so verify the physical form
Related Products under Tariff item 8110.90.00
Antimony Alloy Wire
Antimony alloy wire, drawn and containing over 99% antimony by weight, is a worked article of antimony. It is used primarily in bearing alloys and other industrial applications. This product falls under tariff item 8110.90.00 as 'Other' articles of antimony, not elsewhere specified.
Antimony Anode Bars
Cast antimony anode bars, fabricated for use in electroplating processes, are worked articles of antimony. Their high purity distinguishes them from antimony alloys. These bars fall under tariff item 8110.90.00 as 'Other' articles of antimony.
Antimony Ingots
Pure antimony ingots, containing over 99% antimony by weight, are used in alloy production and flame retardants. Although ingots are typically unwrought, if they have been further worked or are not in a form specified elsewhere, they may fall under this item. This product is classified under tariff item 8110.90.00 as 'Other' articles of antimony.
Antimony Master Alloy Billets
Antimony master alloy billets, where antimony predominates by weight over each other element, are solid extruded or cast products used primarily as an additive in lead-acid battery manufacturing. They are classified under tariff item 8110.90.00 as 'other' articles of antimony, since they are not unwrought metal, waste, scrap, or powders. The billets are worked after casting (e.g., extruded or machined) and do not assume the character of a finished article of another heading.
Antimony Powder for Flame Retardants
Processed antimony powder, micronized for dispersion in plastics as a flame retardant, is a worked article of antimony. It is not a chemical compound but a metallic powder in article form. This product falls under tariff item 8110.90.00 as 'Other' articles of antimony.
Antimony Rods for Soldering
Solid antimony rods, extruded for use in specialty soldering applications, are worked articles of antimony. Their pure form, exceeding 99% antimony, excludes them from alloy classification. These rods fall under tariff item 8110.90.00 as 'Other' articles of antimony.
