Seafood Certifications Explained: What Buyers Sourcing from Vietnam Actually Need

Certifications can feel like alphabet soup — ASC, BAP, HACCP, GlobalG.A.P., EU approval numbers. But knowing which ones actually matter for your market can save you from expensive mistakes.
I managed operations at Espersen Vietnam, an EU-certified facility, for over 8 years. I’ve been through audits and watched shipments get rejected at customs because of certification gaps. Here’s my practical take.

Major Certifications — What They Cover and Who Requires Them

What Each Certification Actually Tells You

HACCP

Hazard Analysis Critical Control Points — a systematic approach to identifying and controlling biological, chemical, and physical hazards in food production. HACCP is the baseline. Without it, a factory cannot export to Japan or the EU. With it, you know the factory has documented control points — but not necessarily that they’re working. HACCP certification says the system exists; an audit tells you whether it’s being followed.

EU Approval Number

If you’re buying for European customers, this is non-negotiable. Vietnam’s food safety authority (NAFIQAD) maintains a list of factories approved to export to the EU. Only factories on this list can ship to European buyers. The list changes — approvals are suspended or removed following inspection failures or border rejections. Always verify the factory’s EU approval status is current before placing an order.

ASC (Aquaculture Stewardship Council)

ASC certifies aquaculture farms — not processing plants — against environmental and social standards. It matters for buyers supplying retailers or buyers who have sustainability commitments. EU retailers increasingly require ASC on farmed species (shrimp, pangasius). The certification is at farm level, which means the factory must source from ASC-certified farms and maintain chain of custody documentation. Not all factories that claim ASC compliance have current, audited chain of custody.

BAP (Best Aquaculture Practices)

BAP is the US market equivalent of ASC — administered by the Global Seafood Alliance. More common in factories that export to US retail. BAP covers farms, hatcheries, processing plants, and feed mills — you can have 1-star to 4-star certification depending on how many links in the chain are certified. US buyers often specify minimum BAP star level.

GACC (General Administration of Customs, China)

Since January 2022, all seafood exported to China must come from GACC-registered facilities. This caught many buyers off guard — factories that had been shipping to China for years suddenly needed to re-register. If you’re sourcing for Chinese buyers, check GACC registration status specifically. It’s separate from EU approval and HACCP.

What I Check When Vetting a Factory

Certifications are the starting point — not the conclusion. Here’s what I verify beyond the certificate:

• Certificate validity date: Certifications expire. I check that the certificate on file is current — not a scan of an expired document that the factory hasn’t got around to replacing on its brochure.
• Audit history: I ask to see the last 2 years of audit reports, including non-conformances and corrective actions. A factory with a clean audit history is more reassuring than one that shows no non-conformances — no production facility at scale runs perfectly. What matters is whether problems were identified and resolved.
• Border rejection records: EU and Japanese customs authorities publish rejection notices. I check whether the factory has had product rejected at import in the last 2 years — and what the reason was. A histamine rejection for mackerel two years ago tells me something important about how the factory handles high-risk species today.
• Chain of custody for sustainability claims: ASC and MSC chain of custody must be maintained through the supply chain. I verify that the factory can provide lot-level traceability documentation — not just a copy of the farm’s certificate.

Which Certifications Your Market Actually Requires

• EU buyers: EU Approval Number (mandatory) + HACCP (mandatory) + ASC or GlobalG.A.P. if farmed species for retail
• Japan buyers: HACCP (mandatory) + JAS compliance for labelling + histamine and residue test documentation per shipment
• Hong Kong buyers: HACCP + flexible on sustainability certifications — HK is a re-export hub, requirements depend on final destination
• China buyers: GACC registration (mandatory since 2022) + Chinese CIQ inspection on arrival
• US buyers: FDA registration + BAP preferred for retail + HACCP
