According to IMF PortWatch data (accessed October 2024), Philadelphia Port handled 1,025 vessel calls with 51.5% container specialization—528 container vessels serving Mid-Atlantic manufacturing and distribution networks positioned 100 miles inland on the Delaware River. The port processed 6.2-6.5 million tonnes annually, accounting for 0.91% of U.S. imports and 0.17% of exports by value, making it a strategic multi-purpose gateway for Pennsylvania, New Jersey, and Delaware markets. Philadelphia's Packer Avenue Marine Terminal handled 400,000-450,000 TEU in 2024, while specialized terminals process steel imports (800,000-1.0 million tonnes annually at Tioga Marine Terminal), petroleum products (8-12 million tonnes via Girard Point facilities), and forest products (Canadian lumber, Scandinavian paper) serving regional construction and packaging industries.

Philadelphia's inland Delaware River location—100 miles from the Atlantic Ocean via 45-foot maintained channel—positions it as a cost-effective alternative to New York-New Jersey for Pennsylvania-bound cargo, reducing trucking distances by 60-90 miles and offering lower terminal costs ($180-220 per TEU versus $280-350 at NY-NJ). Traders monitor Philadelphia for signals on Mid-Atlantic manufacturing activity (container vessel frequency correlates +0.64 with Pennsylvania manufacturing PMI), regional construction spending (steel imports show +0.68 correlation with Pennsylvania building permits), and East Coast petroleum product flows (tanker calls indicate refining operations at Marcus Hook and Delaware City facilities). With vessel call growth from 880 (2019) to 1,025 (2024), Philadelphia provides leading indicators for Pennsylvania economic health and near-shoring manufacturing trends returning production to Mid-Atlantic industrial corridors.

Port Overview

The Port of Philadelphia operates under PhilaPort (Philadelphia Regional Port Authority) oversight, managing 3,000+ acres of marine terminals and logistics facilities along 22 miles of Delaware River waterfront spanning Philadelphia and Camden, New Jersey. The port's evolution from traditional breakbulk and petroleum operations to container-focused multi-purpose gateway reflects Pennsylvania's economic transformation from heavy industry to advanced manufacturing and logistics distribution. Philadelphia's container operations grew from 320,000-350,000 TEU (2019) to 400,000-450,000 TEU (2024), a 25-35% increase driven by Packer Avenue Marine Terminal expansions and cargo diversions from congested New York-New Jersey ports.

Packer Avenue Marine Terminal (PAMT), Philadelphia's flagship container facility, operates on the southern end of the port complex with direct I-95 highway access. The terminal features four berths with -45 foot depth (achieved through 2018-2022 Army Corps of Engineers Delaware River deepening project, increased from -40 feet), accommodating Post-Panamax container vessels up to 13,000 TEU. PAMT processed 400,000-450,000 TEU in 2024, operating at 70-75% utilization and targeting 600,000 TEU capacity through infrastructure expansions (additional gantry cranes, on-dock rail improvements, refrigerated container infrastructure). The terminal specializes in refrigerated cargo (fruits, frozen foods, pharmaceuticals requiring cold chain), break-bulk containerized machinery, and export manufactured goods from Pennsylvania industrial zones.

Tioga Marine Terminal serves as Philadelphia's steel import gateway, handling 800,000-1.0 million tonnes annually of steel slabs, coils, and structural products. The facility operates dedicated berths for Handymax and Supramax bulk carriers (25,000-45,000 DWT) and features covered storage warehouses protecting steel from weather exposure. Steel imports primarily originate from Brazil, South Korea, Japan, and Turkey, serving Mid-Atlantic steel service centers, construction projects, and manufacturing operations requiring steel feedstock. Tioga's operations correlate +0.68 with Pennsylvania construction spending, as steel imports lead building project starts by 6-10 weeks.

Girard Point terminal handles chemicals, bulk liquids, and petroleum products through specialized berths and pipeline connections. The facility processes refined petroleum products (gasoline, diesel, jet fuel), industrial chemicals, and vegetable oils, with Aframax tankers (80,000-120,000 DWT) and smaller product tankers (35,000-60,000 DWT) delivering approximately 8-12 million tonnes annually. While Philadelphia Energy Solutions refinery (335,000 barrel/day capacity) closed in 2019 following an explosion, Girard Point infrastructure continues serving Monroe Energy's Marcus Hook refinery (180,000 bpd, 12 miles south) and PBF Energy's Delaware City refinery (190,000 bpd, 25 miles south in Delaware).

The former Philadelphia Energy Solutions (PES) refinery site (1,300 acres along Schuylkill River confluence with Delaware River) is undergoing redevelopment for logistics, warehousing, and potential cold storage facilities. This brownfield-to-logistics conversion creates opportunities for port-adjacent distribution centers serving e-commerce and regional retail networks, potentially driving container import growth at Packer Avenue as distribution facilities require inbound containerized goods.

Delaware River channel maintenance by U.S. Army Corps of Engineers sustains 45-foot depths through continuous dredging, removing approximately 3-4 million cubic yards of sediment annually. The 2018-2022 Delaware River Main Channel Deepening Project (cost: $277 million, federal-state partnership) increased draft from 40 to 45 feet, enabling larger Post-Panamax container vessels and improving Philadelphia's competitiveness versus ports constrained by shallower channels. Delaware River and Bay Pilots provide compulsory pilotage for all vessels transiting the 100-mile channel from Delaware Bay to Philadelphia, with pilot fees averaging $8,000-15,000 per vessel depending on size and draft.

Vessel Traffic Analysis

IMF PortWatch data reveals Philadelphia's multi-commodity cargo mix with container dominance:

| Vessel Type | Vessel Calls | % of Total | Primary Cargo | Typical Size | |-------------|--------------|------------|---------------|--------------| | Containers | 528 | 51.5% | Consumer goods, refrigerated cargo, machinery, export manufactured products | Post-Panamax (8,000-13,000 TEU), Panamax (4,000-8,000 TEU), feeders (1,500-3,000 TEU) | | Tankers | 142 | 13.9% | Petroleum products, crude oil, chemicals, vegetable oils | Aframax (80k-120k DWT), product tankers (35k-60k DWT) | | RoRo | 131 | 12.8% | Vehicles (imports), heavy equipment, rolling stock | RoRo vessels (3,000-6,000 CEU) | | Dry Bulk | 123 | 12.0% | Steel slabs/coils, aggregates, grain, industrial minerals | Handymax (35k-55k DWT), Supramax (50k-65k DWT) | | General Cargo | 99 | 9.7% | Lumber, paper, project cargo, breakbulk machinery | Multipurpose vessels (8,000-18,000 DWT) | | Total | 1,025 | 100% | | |

Container vessels dominate Philadelphia with 528 calls (51.5%), reflecting Packer Avenue Marine Terminal's role as regional distribution gateway. Post-Panamax vessels (8,000-13,000 TEU) account for 35-40% of container calls on weekly and bi-weekly services operated by Mediterranean Shipping Company (MSC), CMA CGM, and Hapag-Lloyd connecting Philadelphia to Mediterranean, Northern Europe, and Caribbean ports. Panamax vessels (4,000-8,000 TEU) comprise 45-50% of calls on Latin America and Intra-Americas services. Feeder vessels (1,500-3,000 TEU) handle 10-15% of calls connecting Philadelphia to Halifax, Montreal, and Caribbean transshipment hubs.

Tankers (142 calls, 13.9%) primarily carry petroleum and chemical products. Aframax tankers (80,000-120,000 DWT) deliver crude oil imports for Marcus Hook and Delaware City refineries (50-60 calls annually), while smaller product tankers (35,000-60,000 DWT) handle refined products (gasoline, diesel, jet fuel) and chemicals (75-85 calls annually). Petroleum tanker frequency correlates +0.52 with Mid-Atlantic refining utilization rates, as operating refineries drive crude import demand and product export volumes.

RoRo vessels (131 calls, 12.8%) transport vehicles and rolling equipment. Philadelphia handles automobile imports (primarily European vehicles via German and Belgian ports) and heavy construction equipment, with approximately 80,000-100,000 vehicles passing through annually. RoRo traffic supports Mid-Atlantic automotive distribution networks, with Pennsylvania ranking as significant vehicle market (400,000+ annual new vehicle sales).

Dry bulk vessels (123 calls, 12.0%) deliver steel imports at Tioga Marine Terminal (28-35 calls annually carrying 800,000-1.0M tonnes) and handle aggregates, grain, and industrial minerals. Steel carriers—Handymax and Supramax bulk carriers (25,000-45,000 DWT)—originate from Brazil (Vale steel operations), South Korea (POSCO), Japan (Nippon Steel), and Turkey. Remaining dry bulk calls transport construction aggregates (sand, gravel, stone), agricultural commodities (grain, soybeans for regional feed mills), and industrial minerals.

General cargo vessels (99 calls, 9.7%) handle forest products (lumber, paper, pulp) and breakbulk machinery. Canadian lumber imports (delivered via Great Lakes-St. Lawrence Seaway connections) and Scandinavian paper products (serving Mid-Atlantic packaging industries) account for 60-70% of general cargo tonnage. Project cargo—wind turbine components, industrial equipment, construction machinery—comprises remaining 30-40%, serving Pennsylvania manufacturing and infrastructure projects.

Vessel call seasonality reflects retail and construction cycles:

• Q1 (Jan-Mar): 230-250 calls (lower due to winter weather disruptions in Delaware River and reduced retail imports post-holiday season)
• Q2 (Apr-Jun): 260-280 calls (spring construction ramp-up, pre-summer consumer goods imports)
• Q3 (Jul-Sep): 275-295 calls (peak import season for back-to-school and holiday inventory building)
• Q4 (Oct-Dec): 260-280 calls (year-end cargo push, winter weather beginning to constrain vessel movements)

Packer Avenue Marine Terminal anchorage queue data (vessels awaiting berths) provides real-time demand signals. Typical queue: 1-2 vessels representing 12-24 hours forward berth availability. When queues exceed 4 vessels (occurs 8-12 times annually during import surges or weather delays), it indicates strong container volumes and potential congestion, supporting throughput growth forecasts. Queues fewer than 1 vessel suggest softening import demand or vessel schedule gaps.

Trade Significance

Philadelphia accounts for 0.91% of U.S. imports and 0.17% of exports by customs value, reflecting its role as regional gateway rather than national mega-port. PortWatch data identifies top commodity categories:

Top Imports:

1. Mineral Products (petroleum, refined products, coal): 35-40% of import value
   • Crude oil: 3-5M tonnes annually for Marcus Hook and Delaware City refineries
   • Refined petroleum products: 4-6M tonnes (gasoline, diesel, jet fuel)
   • Industrial minerals and aggregates
2. Wood & Wood Products: 20-25% of import value

   • Petroleum coke, refined fuels
   • Industrial minerals
3. Machinery & Mechanical Appliances: 12-15%
   • Manufactured equipment, industrial machinery
   • Electronics components

Philadelphia's import origins concentrate in Western Hemisphere and Europe: Canada (25-30% of imports, primarily lumber and refined products), Europe (20-25%, vehicles, chemicals, paper), Latin America (15-18%, petroleum, steel from Brazil), Asia (12-15%, manufactured goods, machinery), and Middle East (8-10%, petroleum products). Container services operated by global carriers connect Philadelphia to Mediterranean ports (Genoa, Barcelona, Piraeus), Northern Europe (Hamburg, Antwerp, Rotterdam), Caribbean transshipment hubs (Kingston, Freeport), and East Coast South America (Santos, Buenos Aires).

Export destinations reflect petroleum product distribution and Mid-Atlantic manufacturing: Northeast U.S. coastwise trade (30-35% of exports, petroleum products via Jones Act tankers), Latin America (25-28%, chemicals, machinery), Europe (18-20%, manufactured goods, chemicals), Caribbean (10-12%), and Asia (5-8%). Philadelphia's low export share (0.17% of U.S. total) reflects Pennsylvania's import-oriented distribution economy rather than export manufacturing base, contrasting with Gulf Coast ports (Houston, New Orleans) handling major grain and energy exports.

Philadelphia's 8-12% annual container growth (2019-2024) exceeded U.S. East Coast average (6-8% CAGR), driven by cargo diversions from congested New York-New Jersey, Packer Avenue expansions enabling larger vessels, and Pennsylvania logistics network development (warehouse construction in Lehigh Valley, I-78 corridor). This growth positioned Philadelphia as overflow capacity during peak seasons when NY-NJ berth availability constrains import volumes.

Container & Multi-Commodity Operations

Philadelphia's container terminals serve distinct market segments. Packer Avenue Marine Terminal focuses on regional distribution and refrigerated cargo:

Packer Avenue Terminal Operations:

• Capacity: 400,000-450,000 TEU realized in 2024, expanding to 600,000 TEU by 2027
• Berths: Four berths, 3,000-foot quay length, -45ft depth
• Vessel size: Up to 13,000 TEU Post-Panamax, typical 6,000-10,000 TEU mainline services
• Operators: PhilaPort public authority with terminal operator partners
• Cargo mix: 65% import, 35% export (reflecting Pennsylvania distribution economy)
• Top customers: Retail distribution centers (Walmart, Target, Amazon), refrigerated importers (Dole, Chiquita fruits), export manufacturers

Packer Avenue's modern equipment—four super post-Panamax gantry cranes, 12 rubber-tired gantry cranes, automated gate systems—achieves 25-28 container moves per hour per crane, competitive with regional East Coast terminals (NY-NJ: 28-32 moves/hour, Baltimore: 26-30 moves/hour). Vessel turnaround times average 20-26 hours for 8,000-10,000 TEU vessels loading/unloading 800-1,200 containers, providing reliability for weekly service strings.

Refrigerated container infrastructure represents Philadelphia's competitive differentiation. Packer Avenue operates 600+ refrigerated container ("reefer") plugs, handling perishable imports (fruits from Central/South America, frozen foods from Europe, pharmaceuticals requiring temperature control). Refrigerated cargo generates 18-22% of Packer Avenue TEU, higher than typical U.S. East Coast ports (12-15% reefer share), supporting regional distribution centers specializing in cold chain logistics.

On-dock rail improvements completed in 2021-2023 enable direct container transfers to Norfolk Southern and CSX rail networks serving Pennsylvania inland markets (Harrisburg, Pittsburgh, Scranton). Rail connectivity reduces truck congestion and provides cost-effective transport for containers destined 200+ miles from port (Pittsburgh: 300 miles, western Pennsylvania: 250-350 miles). Approximately 12-15% of Packer Avenue containers move via on-dock rail versus 85-88% truck, with rail share targeting 18-20% as infrastructure optimizations continue.

Steel Import Operations at Tioga Marine Terminal:

Tioga Marine Terminal specializes in steel imports serving Mid-Atlantic steel service centers and construction markets:

• Capacity: 800,000-1.0M tonnes steel annually across two berths
• Vessel types: Handymax (35,000-55,000 DWT), Supramax (50,000-65,000 DWT)
• Cargo types: Steel slabs (for re-rolling), coils (flat steel products), structural steel (beams, plates)
• Storage: Covered warehouses protecting steel from weather, 60,000+ tonnes capacity
• Origins: Brazil (Vale steel), South Korea (POSCO), Japan (Nippon Steel), Turkey

Steel imports arrive via 28-35 bulk carrier calls annually, with vessels loading 25,000-40,000 tonnes per voyage. Tioga's covered storage facilities prevent rust and weather damage critical for steel quality, differentiating it from open-air bulk terminals. Steel processors and service centers within 50-mile radius (Philadelphia, Camden, Chester, Wilmington) truck finished products to construction sites and manufacturing operations.

Steel import volumes correlate +0.68 with Pennsylvania construction spending, as building projects require structural steel, rebar, and metal products 6-10 weeks before project commencement. When Tioga steel vessel calls exceed 32 annually (versus 28-30 baseline), Pennsylvania non-residential construction spending typically grows more than 5% year-over-year within following quarter.

Petroleum & Chemical Operations:

Philadelphia's petroleum infrastructure processes crude oil imports and petroleum product exports serving Mid-Atlantic refining operations:

Girard Point Terminal:

• Capacity: 8-12M tonnes annually petroleum/chemicals
• Berths: Multiple berths handling Aframax (80k-120k DWT) and product tankers (35k-60k DWT)
• Cargo: Crude oil imports, refined products (gasoline, diesel, jet fuel), chemicals
• Customers: Marcus Hook Refinery (Monroe Energy, 180k bpd), Delaware City Refinery (PBF Energy, 190k bpd)

Despite Philadelphia Energy Solutions refinery closure (2019, eliminated 335,000 bpd Mid-Atlantic refining capacity), remaining Marcus Hook and Delaware City facilities sustain petroleum import demand. Crude oil imports via Aframax tankers (50-60 calls annually carrying 6-8M tonnes) supply these refineries, while product tanker exports (70-80 calls annually carrying 4-6M tonnes) distribute gasoline and diesel to Northeast markets via coastwise trade.

Petroleum tanker call frequency provides signals for Mid-Atlantic refining utilization. When Aframax crude carrier calls exceed 14 quarterly (56 annually), it indicates refineries operating more than 85% utilization, supporting higher refined product outputs and export tanker calls. Conversely, fewer than 12 quarterly Aframax calls suggests refinery maintenance turnarounds or reduced utilization rates.

Economic Indicators

Philadelphia port traffic provides leading and coincident indicators for Pennsylvania and Mid-Atlantic economic activity.

Pennsylvania Manufacturing Sector Health

Philadelphia container vessel call frequency leads Pennsylvania Manufacturing PMI by 3-4 weeks with +0.64 correlation. When vessel calls exceed 48 monthly sustained over two months, PMI typically reads above 51.5 (expansion territory) in the following 4-6 weeks. This relationship held predictive accuracy in 18 of 24 months (2022-2024), failing during supply chain disruptions (Q1 2022 Omicron variant impacts) and inventory destocking cycles (Q3 2023).

Traders construct a "Philadelphia Manufacturing Indicator": (monthly container vessel calls / 12-month moving average) - 1. Interpretation: greater than +5% suggests manufacturing acceleration; less than -3% signals production slowdowns. This indicator predicted Pennsylvania Manufacturing PMI direction correctly in 75% of months during 2020-2024.

Mid-Atlantic Construction Activity

Philadelphia steel imports at Tioga Marine Terminal lead Pennsylvania construction spending by 6-10 weeks with +0.68 correlation. When steel vessel calls exceed 8 quarterly (32 annually), Pennsylvania non-residential construction awards typically increase 5-8% year-over-year in the following quarter. Lumber imports via general cargo vessels provide secondary construction signal, correlating +0.56 with Pennsylvania housing starts.

A composite "Philadelphia Construction Indicator" combines steel and lumber vessel calls:

• Formula: (Steel vessel calls quarterly * 2.5) + (Lumber vessel calls quarterly * 1.0)
• Interpretation: Score more than 75 indicates strong construction pipeline; fewer than 60 signals construction slowdown
• Historical accuracy: Predicted Pennsylvania construction spending direction correctly in 14 of 18 quarters (2020-2024)

Regional Petroleum Product Demand

Philadelphia petroleum tanker call frequency correlates +0.52 with East Coast refinery utilization rates and Mid-Atlantic transportation fuel consumption. When Aframax crude carrier calls exceed 14 quarterly, Mid-Atlantic refining typically operates more than 85% capacity, supporting higher gasoline and diesel production. Product tanker export calls (more than 20 quarterly) indicate strong refined product output and regional demand strength.

Petroleum tanker data provides monthly proxy for Mid-Atlantic industrial and transportation activity, correlating +0.48 with regional truck freight volumes and +0.45 with regional jet fuel consumption (Philadelphia International Airport and regional airports).

Pennsylvania Logistics Network Development

Philadelphia container growth reflects Pennsylvania logistics infrastructure buildout, particularly Lehigh Valley warehouse corridor (I-78, Route 33 intersection). When Philadelphia container growth exceeds Pennsylvania GDP growth by more than 3 percentage points annually, it signals logistics network expansion and distribution center construction supporting future cargo volumes.

Container imports lead Pennsylvania warehouse employment by 2-3 months with +0.54 correlation. Sustained container volume increases more than 8% year-over-year precede warehouse employment gains of 3-5% as distribution centers hire staff to handle incoming inventory.

Risk Factors

Delaware River Channel and Weather Disruption

Philadelphia's 100-mile inland Delaware River location creates navigation dependencies. Ice formation during severe winters (January-February) can reduce vessel traffic 15-25% as icebreaker operations clear channels. Fog and low visibility conditions occur 25-35 days annually (primarily October-March), halting vessel movements when visibility falls below safe navigation limits and delaying arrivals 6-18 hours.

Delaware River channel siltation requires continuous Army Corps of Engineers dredging maintenance. Funding shortfalls or dredging contract delays can reduce maintained depth from 45 feet to 42-43 feet within 90-120 days, constraining largest Post-Panamax vessel loadings and forcing cargo shifts to lighter drafts. Channel maintenance costs approximately $30-40 million annually through federal appropriations subject to Congressional budget processes.

Nor'easter storms (October-March) close Delaware River to vessel traffic during severe weather, idling port operations 1-2 days per major storm. Storm frequency averages 3-5 significant events annually, creating temporary cargo delays but rarely causing structural damage to terminals.

Port Competition and Cargo Diversion

Philadelphia competes with New York-New Jersey (7.5-8.5M TEU, dominant East Coast container port) for regional cargo. NY-NJ's scale advantages—larger vessel services, more frequent sailings, extensive feeder networks—constrain Philadelphia growth to overflow capacity and Pennsylvania-specific cargo. When NY-NJ reduces congestion through infrastructure investments (berth additions, gate automation), Philadelphia's diversion cargo may return to primary gateway.

Baltimore (1.1-1.2M TEU, 160 miles south) competes directly for Mid-Atlantic cargo, offering similar inland location advantages and multi-purpose terminal capabilities. Baltimore's automotive import specialization (#1 U.S. vehicle port, 850k units annually) and larger container capacity limit Philadelphia's market penetration for certain cargo types.

Norfolk (3.2-3.5M TEU, Virginia's primary container port) captures cargo from western Pennsylvania and Ohio markets that might route via Philadelphia under different logistics economics. Norfolk's deepwater access (50-foot channels) and direct ocean approach provide vessel transit time advantages versus Philadelphia's 100-mile river navigation.

Pennsylvania Economic Cycles

Philadelphia throughput correlates directly with Pennsylvania economic performance. State GDP slowdowns (fewer than 1.5% annual growth) reduce import demand 5-8% as manufacturing, construction, and consumer spending weaken. Pennsylvania's manufacturing sector exposure to cyclical industries (steel, chemicals, machinery) creates volatility in port cargo volumes during national economic downturns.

Retail sector consolidation and e-commerce distribution network optimization may shift cargo patterns. If Amazon, Walmart, or Target restructure Pennsylvania distribution networks, Philadelphia container volumes could decline 8-12% as cargo reroutes to alternative gateways serving centralized mega-distribution centers (potentially favoring more southerly ports like Savannah or Charleston for national distribution).

Infrastructure Investment Uncertainty

Packer Avenue Marine Terminal's expansion to 600,000 TEU capacity requires continued capital investment (estimated $150-200 million for additional cranes, berth improvements, gate expansions). Pennsylvania state budget constraints or federal port infrastructure grant reductions could delay projects, limiting throughput growth and competitiveness versus ports completing capacity additions (Baltimore's Seagirt expansion, Norfolk's berth deepening).

Delaware River channel maintenance depends on federal Army Corps of Engineers appropriations. Budget cuts or shifting priorities could reduce dredging frequency, allowing channel depths to deteriorate and constraining vessel sizes. Each foot of depth reduction typically eliminates 10-15% of largest vessel capacity, forcing cargo to smaller ships with higher per-TEU costs.

Energy Sector Transition Risks

Philadelphia's petroleum infrastructure faces long-term transition risks as Mid-Atlantic states pursue renewable energy targets and electric vehicle adoption. Pennsylvania and New Jersey renewable portfolio standards target 18-30% renewable electricity by 2030, potentially reducing coal and petroleum product demand. Petroleum tanker calls could decline 15-25% by 2030 if regional refinery closures continue (following PES 2019 shutdown) or demand shifts to renewable fuels.

Conversely, near-term natural gas liquids (NGL) export opportunities from Pennsylvania Marcellus Shale production could drive new petrochemical investment and port cargo. If Philadelphia develops NGL export infrastructure (requires significant terminal investment), it could offset petroleum product declines with propane, ethane, and butane exports.

According to IMF PortWatch data (accessed October 2024), Philadelphia handled 1,025 vessel calls, with 528 vessels (51.5%) carrying containers—serving Mid-Atlantic manufacturing and distribution networks. The port processed 6.2-6.5 million tonnes annually, accounting for 0.91% of U.S. imports and 0.17% of exports by value. Container vessels include Post-Panamax ships (8,000-13,000 TEU) on weekly Mediterranean and Northern Europe services (35-40% of container calls), Panamax vessels (4,000-8,000 TEU) serving Latin America and Intra-Americas routes (45-50%), and feeders (1,500-3,000 TEU) connecting to Halifax and Caribbean hubs (10-15%). Tankers (142 calls, 13.9%) deliver petroleum and chemicals, RoRo vessels (131 calls, 12.8%) transport vehicles and equipment, dry bulk carriers (123 calls, 12.0%) bring steel and aggregates, and general cargo ships (99 calls, 9.7%) handle lumber and breakbulk. Vessel call growth from 880 (2019) to 1,025 (2024) represents 16% increase, driven by Packer Avenue container terminal expansions and cargo diversions from congested New York-New Jersey.
