Alan Pham | Vietnam Seafood Sourcing Insights A sourcing consultant's notes on Vietnam's seafood market
Quick Answer: Well Trimmed pangasius fillet (red meat off, belly off, fat off) costs $2.30–$2.80/kg FOB Vietnam and is required for EU and Japan retail. Semi Trimmed is $1.80–$2.20/kg for Asian wholesale. Un-Trimmed is $1.40–$1.80/kg for China and Africa volume trade.
Why Trim Level Matters
Pangasius is a fatty fish. The belly flap, red meat layer, and subcutaneous fat affect shelf appearance, moisture retention, and flavor. How much is removed determines the trim level — and the price difference between trim levels can exceed 60%.
Well Trimmed Fillet (WT) — Premium Grade
Spec: Skinless · Boneless · Red Meat Off · Belly Off · Fat Off
All visual imperfections removed. The fillet is clean white, uniform, and retail-ready. Required by EU retail chains (Lidl, Carrefour, Albert Heijn), Japanese foodservice, and premium US buyers.
| Parameter | Detail |
|---|---|
| Red meat | Removed completely |
| Belly flap | Removed |
| Fat | Removed |
| Yield from whole fish | ~28–32% |
| Price FOB HCMC | $2.30–$2.80/kg |
| Best for | EU retail, Japan, Korea supermarket, US premium foodservice |
Semi Trimmed Fillet — Mid-Grade
Spec: Skinless · Boneless · Red Meat On · Belly Trimmed · Fat On
Belly partially removed, red meat retained on the fillet edge. Lower labor cost at factory level. Common in Asian wholesale and Middle East distribution.
| Parameter | Detail |
|---|---|
| Red meat | Present (on edge) |
| Belly flap | Partially trimmed |
| Yield from whole fish | ~35–38% |
| Price FOB HCMC | $1.80–$2.20/kg |
| Best for | Asian foodservice, Middle East wholesale, processing input |
Un-Trimmed Fillet (UT) — Volume Grade
Spec: Skinless · Boneless · Red Meat On · Belly On · Fat On
Deboned and skinned only — no further trimming. Highest yield per fish. Price-sensitive markets including China wet markets and African trading companies.
| Parameter | Detail |
|---|---|
| Red meat | Fully present |
| Belly flap | Intact |
| Yield from whole fish | ~40–44% |
| Price FOB HCMC | $1.40–$1.80/kg |
| Best for | China wet market, Africa, fish paste/surimi input |
Moisture Content: The Hidden Variable
Trim level alone does not tell the full story. A Well Trimmed fillet at 88% moisture and a Semi Trimmed at 87% moisture can end up with similar protein yield per kg. Always specify both trim AND moisture in your purchase order.
| Moisture Spec | Implication |
|---|---|
| 86% | Higher protein density, firmer texture, lower water weight |
| 87–88% ±1% | Industry standard range |
| 88%+ | More water weight, softer texture, lower protein per kg |

About the Author
During my 10 years at A. Espersen A/S’s Vietnamese subsidiary — Europe’s largest whitefish processor — I reviewed hundreds of pangasius fillet specifications and audited factory trim practices across the Mekong Delta. The trim definitions above reflect what I have verified in commercial production, not catalog language. Enquiries: alan@viet.zone
Well Trimmed (WT) pangasius fillet is skinless, boneless, with red meat removed, belly removed, and fat removed. It is the premium grade required by EU retail, Japanese foodservice, and US premium buyers. FOB price from Vietnam is approximately $2.30–$2.80/kg.
Well Trimmed fillet has the red meat, belly flap, and fat fully removed — resulting in a clean white fillet. Semi Trimmed retains the red meat and most of the fat, with the belly only partially cut. Price difference is typically $0.40–$0.60/kg FOB in favor of Semi Trimmed.
EU retail supermarkets (Lidl, Carrefour, Aldi, Albert Heijn) require Well Trimmed (WT) pangasius fillet as the standard. The clean white appearance and absence of red meat and fat are required for retail display. Semi Trimmed is not acceptable for EU retail packaging.
Trim level and moisture are separate specifications. A Well Trimmed fillet can be produced at 86%, 87%, or 88% moisture depending on factory process and buyer requirement. Both parameters must be specified explicitly in the purchase order — relying on factory default is a common sourcing mistake.
Japan requires Well Trimmed (WT) pangasius fillet with strong preference for low visible fat. Loin and Medallion cuts — portioned from WT fillet — are also popular for deli and izakaya applications. The moisture spec most commonly required for Japan is 87% ±1%.
