Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If having outside diameter less than 215.9 mm
Smaller OD casings use different statistical breaks within the same alloy casing heading.
If welded rather than seamless construction
Welded alloy steel pipes for any use (including drilling) classify under 7306, not seamless 7304.
If used as tubing rather than casing
Drilling tubing has separate provisions from casing based on production vs liner function.

The Tariff Assistant works through the GRI rules on your specific product to reach the right HTS code — and can price the duty on it in the same conversation.
Import Tips & Compliance
• Certify H2S resistance per NACE MR0175 for sour service customs valuation
• Provide thread type (e.g
• BTC) specs to confirm casing classification
• Avoid pitfall: shipping without end protectors leads to damage claims
