Import Tips & Compliance
• Include composite layup diagrams and fiber content % for accurate valuation
• Declare as 'bearing spacer' not 'composite shim' to hold classification
• Test for delamination risks in humid import conditions
Related Products under HTS 8482.99.65
Stainless Steel Ball Bearing Cage
A precision-machined stainless steel cage designed to hold and space steel balls within a ball bearing assembly. It falls under HTS 8482.99.65 as a part of ball or roller bearings, specifically categorized as 'other' parts excluding rings, cages of iron/steel for balls ≥30mm, or thrust ball races. This component ensures proper ball alignment and reduces friction during operation.
Brass Roller Bearing Retainer
A non-ferrous brass retainer that separates and positions rollers in a cylindrical roller bearing. Classified under HTS 8482.99.65 as 'other' bearing parts due to its material (not iron/steel) and exclusion from specific outer ring or thrust race provisions. Essential for maintaining roller spacing in high-speed applications.
Aluminum Outer Bearing Ring Spacer
An aluminum spacer ring that positions the outer race in precision angular contact bearings. It qualifies for HTS 8482.99.65 as an 'other' part, not a full ring or iron/steel cage, used in semiconductor wafer grinders for vibration control. Ensures axial load distribution without qualifying for specific exclusions.
Ceramic Hybrid Bearing Separator
A high-precision ceramic separator for hybrid bearings combining steel races with ceramic balls, used in ultra-high-speed wafer polishers. Falls under HTS 8482.99.65 as 'other' parts, excluding iron/steel cages and due to advanced material not fitting specific subheadings. Critical for minimizing contamination in semiconductor processing.
Precision Plastic Bearing Retainer
Engineered polyimide retainer for miniature ball bearings in wafer slicing saw spindles. HTS 8482.99.65 covers this as 'other' non-metallic bearing part, excluded from metal-specific subheadings, vital for low-outgassing in cleanrooms.
Titanium Needle Roller Bearing Cage
Lightweight titanium cage for needle roller bearings in high-RPM crystal puller spindles. Classified in HTS 8482.99.65 as 'other' bearing parts, not iron/steel and under 30mm ball size exclusion, ideal for semiconductor boule production equipment.
