Showing a curated set of ~800 commonly requisitioned items, not the full 50,000+ item Marine Stores Guide (that catalogue is copyrighted by IMPA and Fuji Trading Co. and available only via a paid data licence). Need a code that isn’t here? Book a demo of Tidal’s full IMPA/ISSA matching engine.

Why a free IMPA lookup tool

Most delays in marine supply start with an ambiguous item description before an RFQ ever goes out. This tool exists to help buyers and chandlers get a quick, reliable answer to "what's the code for this?" without waiting on a licence agreement. It is intentionally a curated subset, not a substitute for the official Marine Stores Guide — for full coverage, bulk matching, and cross-reference against ISSA codes, that requires Tidal's licensed matching engine.

FAQ

Free IMPA lookup, answered

Is this the full IMPA Marine Stores Guide?
No. The official IMPA Marine Stores Guide is a licensed catalogue of 50,000+ items, copyrighted jointly by IMPA and Fuji Trading Company, and only available through a paid data licence. This free tool covers roughly 800 commonly requisitioned marine stores items curated from Tidal's own catalogue, for quick reference. For full IMPA and ISSA code matching against the complete guide, book a demo of Tidal's matching engine.
How do I find the IMPA code for an item?
Type the item description — for example "cotton waste" or "gasket sheet" — into the search box above, or filter by category to browse. Matching results show the code, description, category, and unit of measure for each item.
Does this tool cost anything?
No. This lookup tool is free to use and does not require a signup or account. It runs entirely in your browser.
What if the item I need is not in this tool?
This free tool only covers a curated subset of commonly requisitioned items. Tidal's paid IMPA and ISSA code matching engine resolves free-text descriptions against the full Marine Stores Guide and ISSA catalogue, including bulk requisition matching.

Need to match a whole requisition?

This free tool covers common items one at a time. Tidal's matching engine resolves full requisitions and catalogues against IMPA and ISSA in bulk — live in about a week.
