Ship chandling looks simple from the outside — a vessel needs provisions, stores, or spare parts, and a supplier delivers them. In practice, the gap between a good ship chandler and a mediocre one shows up in the details: whether the meat delivered actually meets the cold chain standard specified, whether the bonded stores documentation will survive a customs audit, whether the deck stores match the exact specification the chief officer ordered rather than a close substitute. This is precisely the gap that ISSA and IMPA standards were created to close.

What ISSA and IMPA Actually Govern

The International Ship Suppliers Association (ISSA) and the International Maritime Purchasing Association (IMPA) maintain standardized product codes, quality benchmarks, and procurement frameworks used across the global ship supply industry. When Sealion categorizes a deck store item under an ISSA code, or quotes a provision order against IMPA's marine catalogue, the vessel's procurement officer knows exactly what they are receiving — without ambiguity, and without relying purely on trust in a supplier's word.

For categories like fresh and frozen provisions, this matters enormously. A delivery of seafood that doesn't meet cold chain integrity isn't just a quality issue — it's a crew health risk. Bonded stores that aren't documented to the correct customs standard create real legal exposure for the vessel at the next port of call. Deck and engine stores that are close-but-not-quite the right specification can mean a critical spare part doesn't fit when it's needed most.

How This Plays Out in Practice at Sealion

Every order processed through Sealion — whether it's fresh provisions for a passing cruise vessel, bonded stores for a tanker, or a full deck and engine stores list for a bulk carrier on a long port stay — is built against ISSA and IMPA reference standards before it ever leaves our warehouse. Combined with our ISO 9001:2015 certified quality management system, this creates a documented, auditable chain from order to delivery that protects both the vessel operator and Sealion.

The result for our clients is straightforward: when you order from Sealion, what you specified is what arrives — categorized correctly, documented properly, and ready for the next customs or class inspection without surprises.
