Ductile fittings

This code covers ductile iron or steel tube and pipe fittings, such as couplings and elbows. Use this code when importing these fittings – duty is generally 5.6%, but may be free depending on the country of origin and any applicable trade agreements, as detailed within Chapter 73.

Detailed information for HTS Code 7307.19.30

This duty applies to articles of iron or steel within Chapter 73, specifically to ductile fittings classified under 7307.19.30, which are cast iron or steel tube or pipe fittings like couplings and elbows. These ductile fittings must contain over 2.5 percent carbon and over 0.02 percent of magnesium or magnesium and cerium by weight to be correctly classified here. Further breakdown exists with statistical suffixes—use .40 for grooved-end fittings, .60 for threaded fittings, .70 for fittings with push-on or flanged joints, and .85 for all other ductile fittings.
