What does a Black List flag mean for a seafarer?

A Black List flag means the flag state has had a statistically high rate of detentions relative to inspections over the previous three-year rolling window. Ships under that flag are targeted more frequently by port-state-control officers, which increases the probability of a prolonged port stay and disrupted schedules.

Does QUALSHIP 21 apply outside the United States?

No. QUALSHIP 21 is a US Coast Guard incentive scheme. A QUALSHIP 21 flag earns reduced USCG examination frequency in US ports, but has no formal effect on Paris MoU, Tokyo MoU, or other PSC regimes, though it is seen as a quality indicator.

Is an ITF FoC flag illegal to sail under?

No. ITF Flags of Convenience are legal registries. The ITF FoC designation reflects the ITF's campaign position that these flags lack a genuine link between the beneficial owner and the flag state, which the ITF argues weakens labour protections. ITF inspectors may board ships in port to verify ITF/IBF agreement compliance.

How often are Paris MoU performance lists updated?

Paris MoU publishes annual performance lists, but the underlying 3-year rolling statistics are updated continuously. The formal White/Grey/Black classification is recalculated and published each year in the Paris MoU Annual Report.

Flag-state risk explained

Four public rating systems assess the regulatory and labour-rights risk attached to a flag state: the Paris MoU White/Grey/Black performance list, the Tokyo MoU equivalent, the US Coast Guard's QUALSHIP 21 incentive scheme, and the ITF Flag of Convenience campaign list. Each uses a different methodology and serves a different audience. Understanding all four is essential when evaluating a job offer, assessing inspection risk on a trade route, or deciding where to register a vessel.

The four rating systems compared

System	Basis	Update cycle	Ratings
Paris MoU	Detention / inspection ratio, 3-year rolling	Annual list	White · Grey · Black
Tokyo MoU	Detention / inspection ratio, 3-year rolling	Annual list	White · Grey · Black
QUALSHIP 21 (USCG)	Positive incentive — ≤ 1% detention + zero current-year detentions	Quarterly	Listed / Not listed
ITF FoC list	Beneficial-ownership test — not a PSC metric	As changed	FoC / Not FoC

Paris MoU — White / Grey / Black

https://www.parismou.org/inspections-risk/performance/criteria-performance-lists

How it is calculated: 3-year rolling ratio of detentions to inspections for all ships of that flag in Paris MoU member ports. Each flag is ranked; those significantly above the mean fall to Grey or Black.

What it means for you: Black = high-risk targeting; expect more frequent, more intrusive PSC inspections in European and North Atlantic ports. Grey = moderate risk. White = low-risk; your ship may qualify for an extended inspection interval under the New Inspection Regime.

Tokyo MoU — White / Grey / Black

https://www.tokyo-mou.org/inspections/flag_performance.php

How it is calculated: Identical 3-year rolling methodology applied to inspections and detentions recorded within the 21 Asia-Pacific member authorities. Performance lists are published annually alongside the Tokyo MoU Annual Report.

What it means for you: A flag can be White in Paris MoU but Grey in Tokyo MoU if its PSC record differs across ocean regions. Check both lists before signing articles, especially if your trade routes include both regions.

QUALSHIP 21 (USCG)

https://www.dco.uscg.mil/Our-Organization/Assistant-Commandant-for-Prevention-Policy-CG-5P/Inspections-Compliance-CG-5PC-/Port-State-Control/Qualship-21/

How it is calculated: Positive-incentive scheme. A flag qualifies if it has: (1) ≥ 10 USCG examinations in the previous 3 years; (2) a detention rate ≤ 1%; (3) zero detentions in the current year; (4) no outstanding deficiencies. Listed flags receive reduced exam frequency in US ports.

What it means for you: Practical benefit in US-trade routes: QUALSHIP 21 ships are less likely to face a USCG exam. The list is reviewed quarterly. A flag that loses QUALSHIP 21 status may see sudden increases in USCG boarding frequency.

ITF Flag of Convenience (FoC)

https://www.itfseafarers.org/en/focs/current-foc-flags

How it is calculated: Not a statistical measure. The ITF applies a beneficial-ownership test: if the dominant beneficial ownership and control of a ship is found to be exercised in a country different from the country of the flag, the flag is FoC. The ITF maintains a campaign list updated periodically.

What it means for you: On an FoC ship, ITF-affiliated inspectors may board in any ITF-active port to check whether an ITF/IBF-approved CBA (Collective Bargaining Agreement) is in force and whether minimum wage scales are being paid. If not, the ITF can call for industrial action. Working under an ITF-approved CBA on an FoC ship provides meaningful wage and repatriation protections.
