Certain bone-in and boneless cured pork products, including hams and shoulders under subheadings 021011 and 021019, are subject to tariff-rate quotas that apply a lower duty rate up to a specified annual volume. Imports above that threshold face a higher over-quota rate. Quota administration is handled by US Customs and Border Protection, and quota fill levels should be monitored before committing to large shipments.

Dried or smoked bovine meat that has not been further processed with added ingredients beyond salt or smoke falls under subheading 021020 of heading 0210. Once the product incorporates sauces, seasonings, or other preparations that change its essential character, it may shift to the prepared meats chapter. The degree of processing and the ingredient composition are the key classification factors.
