Phosphor Bronze Shim Stock Coil
Precision shim stock made from phosphor bronze strip, 0.5 mm thick by 100 mm wide, supplied in coils for machinery alignment and wear plates. Classified under HTS 7409.39.90.30 due to its phosphor bronze composition (copper-tin alloy with phosphorus), thickness >0.15 mm but <5 mm, and narrow width. Excellent wear resistance and non-magnetic properties suit industrial shimming.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If thickness 5 mm or more
Thicker phosphor bronze (>5 mm) moves to 7409.40, separate from thinner sheets.
If refined copper, not alloy
Pure copper sheets use 7409.11; alloys like phosphor bronze require specific subheadings.
If further manufactured into finished articles
Fabricated phosphor bronze parts (e.g., washers) shift to 7419 as articles of copper.

Import Tips & Compliance
• Include chemical analysis report confirming tin predominance and phosphorus content typical of phosphor bronze
• Declare as 'strip' not 'foil' if >0.15 mm; measure uncoiled thickness accurately
