A pangasius processor I worked with years ago had ASC, BAP, and GLOBALG.A.P. certificates framed on the same office wall, and more than one visiting buyer assumed they were three versions of the same thing. They are not. Each scheme was built by a different part of the industry to answer a different question, and buyers who don't know which is which end up requesting a certificate that doesn't actually cover what they're worried about.
ASC: chain of custody and environmental impact, farm to fork
The Aquaculture Stewardship Council standard, created out of a WWF-led initiative in 2010, is built around farm-level environmental and social performance — water use, effluent management, feed sourcing, labor conditions — and then extends that verification through a Chain of Custody certificate that has to be held separately by every processor, cold store, and trader that touches the product afterward. For buyers selling into Northern Europe, ASC matters because it's the standard most retail buyers there recognize by name, and pangasius is the single largest species program ASC runs — Vietnam holds the majority of the world's ASC-certified pangasius farm area, per ASC's own public certificate holder list. The practical catch for buyers: an ASC farm certificate says nothing about the processing plant unless that plant separately holds ASC Chain of Custody. I've seen buyers assume the fillet is covered because the farm is certified, then find out at audit that the processor's CoC lapsed six months earlier.
BAP: the only scheme that certifies the full production chain, star by star
Best Aquaculture Practices, run by the Global Seafood Alliance, takes a different approach — it certifies each stage of the chain independently (hatchery, feed mill, farm, processing plant) and displays the result as a star rating from one to four, depending on how many stages in that specific product's chain are certified. This is the standard I'd point a US buyer toward first, since BAP has the deepest penetration with North American retail and foodservice buyers of any of the three. The detail worth knowing: a 4-star claim on a product only holds if every stage that actually produced that specific batch is certified, not just the processing plant. Ask the exporter for the BAP certificate numbers for each stage, not just the plant's certificate, and check they're current — BAP certificates run on annual audit cycles and lapse quietly if a mill or farm skips a renewal.
GLOBALG.A.P.: farm-level assurance built for retail private-label programs
GLOBALG.A.P.'s Aquaculture module is primarily a farm-level standard, developed originally for European retailer private-label supply chains, and it's the certificate I most often see requested by EU retail buyers who need a documented, audited farm before they'll approve a private-label pangasius or shrimp line. Where it differs from ASC in practice: GLOBALG.A.P. audits are more focused on food safety and traceability documentation at the farm, with less emphasis on the broader social and ecosystem criteria ASC covers. Some Vietnamese farms hold both, since the two schemes address overlapping-but-distinct buyer requirements and dual certification lets a farm sell into both ASC-preferring and GLOBALG.A.P.-preferring retail programs without re-auditing twice from scratch (GLOBALG.A.P. has benchmarking arrangements that reduce duplicate audit scope in some cases).
What to actually request as a buyer
The certificate name on a factory's wall tells you almost nothing on its own — the certificate number does. Before finalizing a contract, I ask for the specific certificate number for the farm, and separately for the processing plant's Chain of Custody or equivalent, and I check both against the scheme's own public certificate database (ASC and GLOBALG.A.P. both publish searchable certificate-holder lists; BAP does as well through GSA). A current certificate number that resolves to the right legal entity and the right product scope is worth more than any laminated wall display. If your current supplier has shown you a certificate but you haven't independently verified the number, that's a five-minute check worth doing before your next shipment, not after a customer audit flags the gap.
Sourcing certified pangasius / shrimp from Vietnam?
I work with international buyers on sourcing, supplier evaluation, and factory inspection. If you're evaluating Vietnamese suppliers for this category, I can help you avoid the common pitfalls.
