TL;DR: Discover **HS codes for flat fish** in 2025 under Chapter 03 (e.g., 0302.21 for halibut), key changes, classification steps, and compliance tips for seamless seafood trade and customs clearance.

What Is the HS Code for Flat Fish in 2025?

HS codes for flat fish** are essential 6-10 digit numbers under **Chapter 03** of the Harmonized System for accurate tariff classification.

Proper use prevents customs delays in seafood shipments.

Types of Flat Fish and Their HS Classifications

Flat fish**, or Pleuronectiformes, are bottom-dwelling species with both eyes on one side, key in international seafood trade.

  • Plaice (Pleuronectes platessa): Affordable flat fish option.
  • Sole (Solea spp.): High-value delicacy.
  • Turbot (Psetta maxima): Gourmet flat fish.
  • Flounder: Versatile for fresh markets.

Always verify **HS code for flat fish** with WCO 2025 nomenclature.
