In trade and culinary contexts, 'scampi' typically refers to Nephrops norvegicus — the same species as Norway lobster or langoustine — and live, fresh, or chilled whole product classifies under 0306340000. However, processed scampi tails or breaded scampi preparations may fall under different chapters (e.g., Chapter 16 prepared crustaceans), so the product's state of preparation at import is the key classification determinant.

Norway lobster (Nephrops norvegicus) is a small clawed nephropid crustacean distinct from both spiny/rock lobsters (Palinuridae, no claws) and the larger clawed Homarus lobsters. Each has its own HS6 heading: 030634 for Nephrops, 030631 for rock lobster, and 030632 for Homarus. Correct species identification — ideally supported by the scientific name on commercial invoices — is essential to avoid misclassification.
