1605.51

Analysis

Subheading 1605.51 covers oysters, within heading 1605. The first six digits are shared by every country that uses the Harmonized System, so this part of the code is the same in the US, UK and EU schedules; the 3 US tariff lines below it are national.

2 of its 3 lines with a percentage rate are duty-free at the general rate (67%) and 1 are dutiable, from duty-free up to 4.7%. The median line pays duty-free.

The US splits it as follows: 1605.51.05 for products containing fish meat; prepared meals (duty-free), 1605.51.40 for other: smoked (duty-free) and 1605.51.50 for other: other (4.7%).

By Census's concordance, most of its statistical lines are made by Seafood Product Preparation and Packaging (311710). Those are the NAICS industries a US producer of these goods would report under.

Goods only reach 1605.51 once they fall within heading 1605 (crustaceans, molluscs and other aquatic invertebrates, prepared or preserved). Under General Rule 6, subheadings are then compared only with others at the same level, so a product is matched against its siblings, not against lines elsewhere in the chapter.
