28 HTS codes in this chapter

Precision instruments and apparatus

Chapters 90 through 92 cover optical, photographic, cinematographic, measuring, control, precision, and medical-surgical instruments (90), clocks and watches (91), and musical instruments (92). Medical and laboratory equipment represents a significant proportion of trade in these chapters. In Mexico, medical devices require COFEPRIS health registration, with processes that can take months. Classification is technical and depends on primary function, instrument precision, and specific application. Many products in these chapters have low or zero duties, especially scientific and medical instruments under WTO agreements.
