Dental fittings, other than artificial teeth.
Classification of dental crowns under HS 9021.29
Dental crowns are classified under HS code 9021.29, which falls within Chapter 90 of the Harmonized System. This chapter encompasses optical, photographic, cinematographic, measuring, checking, precision, medical or surgical instruments and apparatus. Specifically, heading 9021 covers orthopedic appliances, including crutches, surgical belts and trusses; splints and other fracture appliances; artificial parts of the body; hearing aids and other appliances which are worn or carried, or implanted in the body, to compensate for a defect or disability. Within this heading, subheading 9021.21 is reserved for artificial teeth, while 9021.29 is the residual category for \"dental fittings.\" Dental crowns are considered fittings because they are fixed to existing tooth structures or abutments to restore function and aesthetics. The classification is determined by the primary function of the item as a permanent prosthetic replacement for a portion of a tooth. Unlike instruments used to perform dental work, these are artificial parts or fittings that remain in the patient's mouth. The material composition, whether porcelain, gold alloy, or zirconia, does not change the classification under 9021.29, provided the item is a finished dental fitting ready for implantation or attachment.

Codes often confused with 9021.29
Common mistake. Dental crowns are frequently misclassified under HS code 9021.21, which is specifically for artificial teeth (such as those used in full or partial dentures). While both are dental prosthetics, crowns are categorized as fittings under 9021.29. Another common error is using 9018.49, which covers dental instruments; however, because crowns are implanted parts of the body, they must reside in 9021. Additionally, raw ceramic or metal blocks used in CAD/CAM milling are not classified here; they fall under their respective material chapters, such as 6909 for ceramics.

How these figures are built
109 countries reported 2025 trade to UN Comtrade in HS 2022, and their own totals are used. Countries that did not report are estimated from what other countries recorded trading with them. Those estimates miss trade with other non-reporting countries, so they can be low, and a non-reporting country can rank higher than shown or be missing from the list. World totals add both and leave out trade between two non-reporting countries. Figures are in current US dollars; reported imports are mostly valued CIF and exports FOB, and exports include re-exports. The UN Comtrade links show the underlying records; they can also list a few reporters left out here (regional groups and older HS editions).
