It is the premium grade required by EU retail, Japanese foodservice, and US premium buyers. FOB price from Vietnam is approximately $2.30\u2013$2.80\/kg.<\/p><\/div>\n<div class=\"schema-faq-section\" id=\"faq-39345f8b\"><strong class=\"schema-faq-question\">What is the difference between Well Trimmed and Semi Trimmed pangasius?<\/strong> <p class=\"schema-faq-answer\">Well Trimmed fillet has the red meat, belly flap, and fat fully removed \u2014 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\u2013$0.60\/kg FOB in favor of Semi Trimmed.<\/p><\/div>\n<div class=\"schema-faq-section\" id=\"faq-efa00d9b\"><strong class=\"schema-faq-question\">Which pangasius trim level is required for EU retail?<\/strong> <p class=\"schema-faq-answer\">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.<\/p><\/div>\n<div class=\"schema-faq-section\" id=\"faq-12358f2c\"><strong class=\"schema-faq-question\">Does trim level affect the moisture content of pangasius fillet?<\/strong> <p class=\"schema-faq-answer\">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 \u2014 relying on factory default is a common sourcing mistake.<\/p><\/div>\n<div class=\"schema-faq-section\" id=\"faq-654e7593\"><strong class=\"schema-faq-question\">What trim level does Japan require for pangasius fillet?<\/strong> <p class=\"schema-faq-answer\">Japan requires Well Trimmed (WT) pangasius fillet with strong preference for low visible fat. Loin and Medallion cuts \u2014 portioned from WT fillet \u2014 are also popular for deli and izakaya applications. The moisture spec most commonly required for Japan is 87% \u00b11%.<\/p><\/div>\n<\/div>\n","protected":false},"excerpt":{"rendered":"<p>Understand the real difference between Well Trimmed, Semi Trimmed, and Un-Trimmed pangasius fillet from Vietnam \u2014 with price comparison, full specs, and guidance on which trim level fits your market.<\/p>\n","protected":false},"author":1,"featured_media":695,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[17,34],"tags":[],"class_list":["post-691","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-homepage-en","category-products"],"yoast_head":"<!-- This site is optimized with the Yoast SEO plugin v27.3 -
