Contracting in a Rate Slide: Surcharges You Can (and Can’t) Defend

0
9

When spot softens and capacity creeps back, every add-on gets questioned. Owners and NVOs still face real compliance and security costs, but only some surcharges are provably linked to external triggers. The art is separating what is measurable and time-stamped from what looks like margin padding, then contracting for transparency so it survives procurement scrutiny.

Snapshot signals

Most defensible: EU ETS, FuelEU, war risk AP
Conditional: BAF, OPS at berth, canal fees
Often rejected: blanket congestion or generic risk fees
Rules that help: public trigger, clear method, expiry

Buyers look for external triggers, dated evidence, auditable math, and automatic rollback when conditions improve.

Surcharge defensibility matrix Surcharge Trigger and evidence Contract structure that holds up Typical buyer response Keep it credible
EU ETS pass-through Phase 40% → 70% → 100%; first surrender targeted Sep 2025; verified emissions with EUA settlements Voyage emissions × phase share × EUA price; show vintage, registry, surrender month; quarterly true-up Ceiling per TEU or tonne; audit of emission factors Attach verification extract; share a lane sheet with example math
FuelEU Maritime GHG intensity cap from 2025; scope split for intra-EU and at-berth; BDNs and sustainability certificates Separate energy delivered from penalties; keep credits separate to avoid netting disputes Challenges on factors and whether a rotation is in scope Publish well-to-wake factors and a clear scope map per service
War risk AP Listed areas on binder; broker quote with timestamp; days in area and endorsement reference Voyage-specific AP with quote copy; auto-remove when advisory changes; reroute threshold Requests AP cap or Cape comparison One-page AP explainer and re-rate rule tied to the advisory list
Canal or draft surcharge Official draft and slot notice; booking class and date; notice number and effective date Per-transit cost table by booking class; sunset when draft rises or slots increase Immediate rollback when notices improve Bind rollback clause to the same public notice feed
BAF VLSFO basket; HSFO spread if scrubber; fixed look-back with named hubs Four-week average reset first of month; scrubber uplift as separate line Challenges hub mix and spread sensitivity; asks for caps or floors Publish an open calc sheet on each reset and note holiday data gaps
OPS or shore power Port tariff per kWh and connection hours; berth ID and meter reading Only where OPS exists; per-kWh pass-through with log and tariff copy Proof of usage; disallow where OPS unavailable Attach meter, berth, and tariff excerpt for each call
Congestion or emergency Measured dwell beyond SLA using port stats or AIS wait series Activates after X days above threshold; auto-sunsets after seven clean days Weekly evidence and hard expiry dates requested Publish a small dwell table or chart with trigger logic
Scenario bands by lane and condition Lane or condition Green band — usually accepted Amber band — needs documentation Red band — likely rejected
ET surcharge (EU ETS) Verified emissions and EUA settlements attached Estimated emissions with later true-up Lump sum without an emissions basis
FuelEU Maritime Energy and GHG factors published per call Ship-level averages with quarterly true-up Flat fee with no scope reasoning
War risk AP Broker quote and listed area citation Screenshot or summary with quote ID No evidence or open-ended risk adder
BAF Index basket method and look-back shown Single-hub proxy with reset schedule Undefined fuel adders or retroactive edits
Canal or draft Notice number with date and booking class Generic reference to reduction policy Charge persists after notice is relaxed
Congestion Live port dwell exceeds SLA for X days Anecdotal delays with some AIS evidence No data and no sunset date

Negotiation playbook that survives review Topic
What to publish
What buyers accept
What gets rejected
Trigger documents Notice numbers, broker quotes, registry extract Readable PDFs with dates and identifiers Verbal or redacted references without dates
Timing Start and stop rules tied to public events Auto-rollback when the trigger ends Indefinite surcharges with no sunset
Math Simple formula and inputs by lane Spreadsheet shared at each reset Opaque blended figures or moving targets
Risk thresholds Caps per unit with a reroute threshold Choice of AP or detour when the ceiling hits Unlimited pass-through without options
Reconciliation Quarterly true-up with credit notes Clear evidence of over-recovery refund One-way adjustments only

Audit checklist for monthly billing

  • Each surcharge line has a date-stamped trigger and a method line
  • Indexes and quotes archived to a persistent link or attachment
  • Sunset rule applied when the trigger improved during the month
  • True-up credit appears within the next billing cycle if applicable
  • Contact field and mailbox for surcharge queries on each invoice

Reference notes

Structures reflect current practice for EU ETS and FuelEU pass-through, war risk additional premiums in listed areas,
canal draft and booking notices, public bunker indices, and port shore power tariffs. Use the latest official notices,
broker quotes, and index closes when invoicing.

A careful surcharge program is most credible when tied to public triggers, time limits, and checkable math. In a softening market that combination tends to reduce disputes, helps buyers compare options fairly, and lowers the chance of retroactive claims.
