API 11B Steel Sucker Rod
A high-strength carbon steel sucker rod manufactured to API 11B standards, used in oil well reciprocating pumps to transmit mechanical motion from the surface to the downhole pump. It falls under HTS 8413.91.90.65 as a part of subheading 8413.50.00 pumps, specifically sucker rods described in statistical note 3 to chapter 84 for semiconductor manufacturing equipment applications. These rods are engineered for precise linear motion in cleanroom-compatible pumping systems.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If used in oil and gas drilling pumps
Parts of oilfield pumps under 8431.49 fall outside semiconductor-specific statistical note 3, changing classification.
If not specifically for semiconductor wafer processing equipment
General pump parts of 8413.50 not meeting statistical note 3 criteria are classified in the broader 'other' category.
If imported as unfinished rod stock without pump-specific machining
Unmachined steel rods are classified by material composition under Chapter 73 rather than as finished pump parts.

Import Tips & Compliance
• Verify API 11B certification and material composition documentation to confirm classification under statistical note 3
• Include end-use statements proving application in semiconductor manufacturing pumps to avoid reclassification
• Ensure rods meet dimensional tolerances for cleanroom use; common pitfall is missing traceability certificates
