There are only three ways to ship bitumen, and the right one is chosen by what the buyer has at the receiving end — not by what looks cheapest per tonne at the load port.
Every bitumen shipment is a compromise between three things that pull against each other: the freight cost per tonne, the equipment the buyer has at destination, and how fast the cargo can be turned into usable binder. The cheapest freight per tonne is bulk, and bulk also demands the most infrastructure. The lowest infrastructure requirement is drums, and drums carry the highest cost per tonne and by far the most labour. Everything else on this page follows from that tension.
The binder is filled hot at the plant, allowed to set, and then moves as ordinary containerised freight on any liner service that calls at the load port. No special vessel, no special berth, no heated tank at either end. This is why containerised bitumen dominates trade into markets that have asphalt plants but no bitumen terminal.
The published loading figures used across this site are:
Two consequences follow from those numbers. First, what limits a bitumen container is the stack and the road, not the cube and not the container's own plate. Drums are stacked two tiers and no higher, because the binder softens in transit and a third tier deforms the drums beneath it; ten along the length by four across by two tiers is 80 drums, and the tonnage is simply whatever those 80 drums hold. One-tonne bags follow the same floor plan — ten down, ten on top, 20 bags and 20 MT. Both loads sit well inside what the box is entitled to carry: ISO 668 sets the maximum gross mass of a standard 20-foot container at 30,480 kg, the CSC plate on the individual unit governs, and a tare of around 2,250 kg leaves a payload in the region of 28 tonnes. Forty-foot equipment does not recover that headroom, because under ISO 668 it carries the same 30,480 kg maximum gross mass on a heavier tare, so its payload is lower still and a full 40-foot floor plan of drums would exceed it. What genuinely binds first is destination road and axle-weight law, which in several markets caps a single container movement below 20 tonnes of cargo — the reason 150 kg drums at 12 MT per box stay popular in places where 180 kg drums would otherwise be the cheaper packing per tonne.
Second, the drum tare is real weight that travels. A new steel drum weighs roughly 18–22 kg empty, so 80 drums of 180 kg net is 14.4 MT of binder and close to 16 MT gross before the container's own tare. That steel is paid for on the invoice, carried across the ocean, and then becomes a waste-disposal problem at destination. It is also the reason a drummed tonne lands dearer than a bagged tonne even when the product price is identical.
A bitutainer is a tank built inside a standard 20-foot ISO frame, insulated and fitted with a heating system — commonly electric elements or a fuel-fired heater serving internal coils — and a bottom discharge outlet. Payload is 20–25 MT, so roughly 40 to 50 units carry 1,000 MT. Because the frame is ISO-compatible, it moves on the same liner services, the same gantry cranes and the same chassis as a dry box. No jetty, no shore hose, no terminal.
The trade-off is that the product arrives as a single 20-tonne mass of cold bitumen that has to be reheated before anything can be pumped out. That takes power or fuel, it takes a receiving tank, and it takes time measured in days rather than hours. The second trade-off is commercial rather than technical: the unit itself is an asset. Either it returns empty, and somebody pays for the repositioning leg, or it is bought outright with the cargo. Establish which arrangement is being quoted before comparing a bitutainer offer against a drum offer, because the two prices are not describing the same thing.
Bulk parcels move on specialised bitumen tankers or heated product tankers whose cargo tanks are insulated and fitted with heating coils, normally thermal-oil or steam served. The cargo is loaded hot, held hot for the whole voyage, and discharged by the ship's own pumps through a hose or hard-arm connection into shore tanks. Parcel sizes in this trade typically start around 1,000 MT and run into the several thousands depending on the vessel and how many buyers share the voyage.
Bulk is the cheapest way to move bitumen per tonne, with no packing cost at all and no waste to dispose of. It is also the only mode that requires a genuine receiving terminal: a berth the vessel can work, a discharge line that is short, insulated and heat traced, heated storage with the capacity to take the whole parcel, and a defensible way of measuring what came off. Under a charter party the vessel also brings laytime and demurrage into the contract, which is a category of cost that containerised shipments do not have.
The decision is almost always made by the destination, not the origin. A contractor with a drum melter and a yard buys drums. A plant with a receiving tank and a pump buys bitutainers. A terminal or a large asphalt producer with a tank farm buys bulk and stops thinking about packing entirely. Where a buyer is moving from one tier to the next, the honest comparison is landed cost per tonne including the cost of getting the binder out of its packing and into the mixer, not the price on the offer sheet.
The same 1,000 tonnes of binder looks completely different depending on how it is packed. This table converts each mode into the numbers that drive a freight booking and the equipment list at destination.
| Mode | Typical lot or parcel | Net per unit | Units per 1,000 MT | What the buyer must have at destination |
|---|---|---|---|---|
| Steel drums, 150 kg net | 1 FCL upward | 80 drums, 12 MT per 20' FCL | 84 containers | Forklift with drum clamp or slings, level hardstand, drum melter or decanter |
| Steel drums, 180 kg net | 1 FCL upward | 80 drums, 14.4 MT per 20' FCL | 70 containers | As above, with fewer drums to handle and dispose of per tonne |
| Steel drums, 185 kg net | 1 FCL upward | 80 drums, 14.8 MT per 20' FCL | 68 containers | As above; confirm destination gross and axle weight limits first |
| Jumbo or poly bag, 1 MT | 1 FCL upward | 20 bags, 20 MT per 20' FCL | 50 containers | Lifting beam or clamp, and a melting unit that accepts a whole bag |
| Tank container / bitutainer | 1 unit upward | 20–25 MT per unit | 40–50 units | Power or fuel for reheating, a receiving tank, discharge connection |
| Bulk vessel, heated tanks | Typically 1,000 MT and above | Parcel size | One part cargo | Berth, traced and insulated shore line, heated storage, calibrated gauging |
Most bitumen delays are not caused by the ship. They are caused by a receiving facility that was not ready on the day the cargo arrived.
For a bulk parcel the berth has to take the vessel and the discharge line has to be short, insulated and heat traced. A long, cold jetty line will stiffen with product in it and turn a routine discharge into a blocked pipeline.
Tanks with thermal-oil or steam coils, sized for the whole parcel plus the heel already in tank. Hold a paving grade at about 150–165 °C while it is being worked, drop below 150 °C for anything longer, and treat 180–190 °C as an absolute ceiling that is never to be exceeded.
Gear pumps sized for the viscosity at the actual discharge temperature, and hoses rated for hot product. Lines must be blown or flushed clear after discharge, because bitumen left standing in a cold line sets where it stands.
Clamp truck or slings, a level hardstand, covered storage away from standing water, and melting capacity that matches the delivery rate. Eighty drums per container is a lot of individual lifts if the yard is not laid out for it.
A weighbridge for drummed and bagged cargo, or a calibrated tank table plus verified temperature for bulk. Agree the basis before arrival; a hot volume reading and a contract in tonnes are not the same measurement.
Safety Data Sheet on site, bunded tank area, fire cover and hot-work control. If hot bitumen reaches skin, flood the area with clean cold running water and keep it running for at least 20 minutes; adhered bitumen is never peeled off or stripped with solvent, and its removal is a decision for medical staff.
The single most useful question a buyer can ask before booking is simple: in what physical state will this cargo be standing on my yard, and what do I have to do to it before it enters a mixer?
| Mode | Filling or loading temperature | Condition on arrival | Discharge equipment required | Reheating before use |
|---|---|---|---|---|
| Steel drums | Filled at about 140–160 °C | Solid at ambient. Drums may be soft, bulged or seeping at the lid after a hot-climate transit | Clamp truck or slings, hardstand, drum melter or decanter with drum tipping frame | Yes — every drum must be fully melted |
| Jumbo and poly bags | Cast at about 140–160 °C | Solid block inside the bag; bags may deform and adhere to each other under stack load and heat | Lifting beam or crane, melting unit that accepts the whole bag | Yes — a jumbo bag's woven outer and release liner are stripped and the block charged; a meltable poly bag goes into the melter whole |
| Tank container / bitutainer | About 150–165 °C | Well below pumping temperature unless the unit was heated in transit; commonly a single cold mass | Bottom outlet connection, transfer pump or gravity drop, heated receiving tank | Yes — on-board heating brings the product back over a period of days, not hours |
| Bulk vessel, heated tanks | Loaded at about 150–165 °C | Held hot by cargo coils throughout the voyage; typically discharged in the 130–160 °C range | Hose or hard arm, insulated and traced shore line, heated shore tank, gauging | No, provided cargo heating has been maintained for the whole voyage |
Transit time on the bitumen trade lanes ranges from under a week on short Gulf-to-South-Asia routings to well over a month where transhipment is involved. Time is not neutral for this cargo.
Ask for the routing, not just the sailing date. A direct service and a service with one transhipment can quote similar door-to-door windows and then behave completely differently, because every transhipment adds a port call, a lift, a stow decision and an opportunity for the box to miss a connection. For planning, treat transhipment legs as the main source of schedule risk, and build float into the date the melting unit is booked rather than into the date the vessel sails.
Bitumen ages by oxidation, and oxidation runs faster the hotter and longer the binder is held. A bulk parcel held hot for several weeks has a heat history that a drummed cargo simply does not have. The effect is measurable in the same properties the specification is written in: penetration falls, softening point rises, and the binder becomes stiffer than the grade it was loaded as. It is the same oxidation mechanism the rolling thin film oven test (ASTM D2872) reproduces in the laboratory, although that test is calibrated to the short, hot exposure a binder gets in a mixing plant rather than to weeks in a cargo tank. It is also why long holds above about 150 °C are discouraged, and why the industry rule of thumb — hardening roughly doubles for every 10 °C of storage temperature — matters more on a bulk voyage than anywhere else. On a long voyage, ask what temperature the cargo was held at, not only what it was loaded at.
A steel box standing on a terminal apron in the tropics is an oven. Interior temperatures well above ambient are routine, and they sit uncomfortably close to the ring-and-ball softening point of a normal paving grade, which for Bitumen 60/70 falls in the 49–56 °C band. The binder does not turn to liquid, but it softens enough to matter: drums bulge, lids weep at the seam, drums lower in the stack deform under the ones above, and bags slump and stick together. Cargo stowed under deck or in the middle of a stack has a much easier time than a box on the top tier in full sun. This is a real argument for tight, level stowage, proper dunnage and lashing, and for not letting a loaded container sit on a quay for weeks.
Warm, humid air is sealed into a container at stuffing. As the box heats and cools each day it condenses on the underside of the roof and runs down onto the cargo. That water finds drum seams and lids, and it rusts them. It is also a genuine hazard downstream: water trapped at the bottom of a tank or a melting kettle flashes to steam when the product goes past 100 °C and can throw hot bitumen out of the vessel violently. Check drums for standing water before they go anywhere near heat, and check that a shore tank is dry before it takes a hot parcel.
Rusted, dented or leaking drums are a leading cause of disputes when a bitumen container is opened at destination, and reconditioned drums are a large part of why drums arrive in that state. Specify new steel drums explicitly in the contract. Have the loading photographed and have an independent inspector record packing condition, seal numbers and drum count at the load port, because once the box is opened at destination there is no clean way to establish whether damage happened in transit, at the terminal, or during discharge.
The product that suffers most is the one that is heated, cooled, and heated again. Plan to melt once, gradually and uniformly, and to use what is melted. Two things must never happen at the melting point: flame against steel with no product behind it, and a heating coil or element running while any part of it stands proud of the binder. Both scorch the material at the metal face, which contaminates the whole batch and starts fires.
A price per tonne is not a landed cost. Between the filling plant and the mixer there are a dozen separate charges, they sit with different parties depending on the Incoterm, and only some of them move.
| Cost component | What it covers | Normally carried by | Volatility |
|---|---|---|---|
| Product | The binder itself, ex-plant or ex-tank | Seller, inside the offer price | High — tracks crude and heavy residue values |
| Packing | New steel drums, jumbo or poly bags, pallets and dunnage | Seller, inside the offer price | Medium — driven by steel and resin prices |
| Inland haulage at origin | Filling plant to the load port or container yard | Seller under FOB and above | Medium — fuel and trucking capacity |
| Origin terminal handling | Stuffing, lift-on, lashing, seals, weighbridge, port dues | Seller under FOB and above | Low — tariffed and published |
| Export documentation | Certificate of origin, chamber attestation, export clearance | Seller under FOB and above | Low |
| Third-party inspection | Quality, quantity and packing survey with sealed retained samples | As agreed and stated in the contract | Low — a small fraction of cargo value |
| Ocean freight | The container slot, or the vessel for a bulk parcel | Buyer under FOB; seller under CFR and CIF | High — the least predictable line in the whole build-up |
| Freight surcharges | Bunker adjustment, congestion, war risk, peak season, equipment imbalance | Follows whoever pays the freight | High — can move between booking and sailing |
| Marine cargo insurance | Loss or damage cover under Institute Cargo Clauses | Buyer under FOB and CFR; seller under CIF | Low to medium — rises with route risk |
| Destination terminal handling | Discharge, lift-off, gate charges, documentation fees | Buyer, other than under DPU, DAP and DDP | Low — tariffed, but check it is not double charged |
| Import duty and taxes | Duty on HS 2713.20 plus VAT, GST or equivalent | Buyer, other than under DDP | Low day to day, step changes with policy |
| Demurrage, detention and storage | Free time exceeded at the terminal or on the box outside it | Whoever caused the delay, in practice the consignee | Very high, and almost entirely avoidable |
| Discharge and reheating | Drum melting, bitutainer reheat, shore pumping, empty drum disposal | Buyer | Medium — energy cost and labour |
| Inland delivery at destination | Port to plant or site, including any escorted or permitted movement | Buyer, unless the named place under DAP, DPU or DDP is inland | Medium — fuel and local haulage |
Two offers on the same grade can differ by more in freight and destination charges than in the price of the binder. The Incoterm decides which of you is exposed to that.
Under Incoterms 2020 the three rules that dominate bitumen trade are FOB, CFR and CIF. Under all three, risk passes to the buyer once the goods are on board at the port of shipment. What changes is who pays for the voyage: under FOB the buyer arranges and pays the ocean freight and takes the freight-market risk; under CFR the seller pays the freight but not the insurance; under CIF the seller pays freight and buys cargo insurance. A CIF number therefore looks larger than an FOB number for the same cargo and can still be cheaper landed.
Two details are worth knowing before signing. First, FOB, CFR and CIF were written for cargo handed over at the ship's rail, and the International Chamber of Commerce points containerised shippers toward FCA, CPT and CIP instead, because a container is handed to the carrier at a terminal days before it is on board. Using FOB for a container leaves a gap between the moment you lose control and the moment risk formally transfers. Second, the insurance floor differs by rule: under Incoterms 2020, CIF requires only the minimum cover of Institute Cargo Clauses (C), while CIP requires the wider Clauses (A). If you are buying CIF and expect all-risks cover, you must say so in the contract.
At the far end of the scale, DAP and DDP put delivery at destination on the seller, and DDP additionally puts import clearance and duty on the seller. For a market where the seller has no established customs presence, DDP transfers a risk that the seller cannot manage and the buyer can — which usually shows up as a worse price, not a better service.
Ocean freight and its surcharges are the least predictable part of a landed tonne. Rates respond to vessel supply, port congestion, equipment availability and route risk, and surcharges such as bunker adjustment, war risk and congestion can be applied between booking and sailing. Product price moves with crude and heavy residue values. Packing tracks steel. Everything else on the table is comparatively stable. This has one practical consequence: ask how long a quotation is valid and what is fixed within it. A CFR offer with a firm freight component for a defined shipment window is worth more than a lower CFR offer that will be re-priced if the box is not booked immediately.
Petroleum bitumen is classified under HS heading 2713.20, and most destinations apply national subheadings beneath it. Duty is stable until it is not — a tariff change, an anti-dumping measure or a change of preferential origin treatment can move landed cost overnight and by more than a freight swing. Confirm the full destination code and the applicable rate with a local broker before contracting, and check whether a certificate of origin gives access to a preferential rate under a trade agreement. That certificate is a cheap document with a large effect.
These two words are used interchangeably and are not the same thing. Demurrage accrues when a container stays inside the terminal beyond the free time allowed. Detention accrues when the container is out of the terminal, in your yard, beyond the free time allowed for returning it empty. Both are charged per container per day, both escalate in tiers, and free time varies by carrier, trade lane and port. Confirm the free time in the booking rather than assuming a market norm, and remember that on a 70-container shipment a few idle days multiply by seventy.
For a bulk parcel the equivalent exposure is laytime and vessel demurrage under the charter party. If the shore tank cannot take the parcel at the agreed rate, or the discharge line stiffens, the vessel waits and the clock runs at a daily rate that dwarfs container demurrage.
The causes are boringly consistent: documents presented late or with discrepancies, a customs classification query, a missing Safety Data Sheet, an import permit that had lapsed, or a receiving facility that had not emptied and heated its tank before arrival. Almost every one of them is fixed by preparation two weeks earlier, which is why the documentation sequence below is a logistics topic and not an administrative one.
Documentation is the part of bitumen logistics that most often stops the cargo, and it is the part that costs nothing to get right in advance.
Confirm the full destination tariff code beneath HS 2713.20 with a local broker, confirm any import permit or standards registration, and settle packing, container type and the Incoterm. Where product ships hot in a tank, confirm with the carrier whether it must be declared as an elevated-temperature liquid under the IMDG Code — bitumen carried at or above 100 °C is treated differently from drummed product at ambient.
Under SOLAS Chapter VI Regulation 2 the shipper must declare a verified gross mass for every packed container before it can be loaded. For bitumen this is straightforward — net weight plus packing plus container tare — but a missing or late VGM will hold the box at the terminal.
Weighbridge tickets or tank gauging, third-party inspection covering quality, quantity and packing condition, sealed retained samples held by both parties, seal numbers recorded on the packing list, and photographs of the stow. This is the evidence base for any later claim, and it cannot be recreated afterwards.
Bill of lading, commercial invoice, packing list, batch Certificate of Analysis, Technical Data Sheet, Safety Data Sheet, certificate of origin and the inspection certificate. The description of goods, the quantity, the unit and the packing must read identically on every one of them.
Where a letter of credit is used, presentation is governed by UCP 600 and the bank has up to five banking days to examine the documents. A discrepancy is not a technicality — it delays release, and the free-time clock at destination does not pause while it is corrected.
Duty paid, delivery order issued, haulage booked, and the receiving facility genuinely ready: tank empty and hot, melter serviced, yard clear. Reconcile quantity and quality against the load-port certificates while the retained samples and the claim period are still live.
Three. Containerised solid packing — new steel drums or one-tonne jumbo and poly bags — inside a standard 20-foot container. Insulated tank containers, often called bitutainers, carrying 20 to 25 MT each and moving on the same liner services. And bulk parcels on vessels with insulated, coil-heated cargo tanks, typically from 1,000 MT upward, discharged into a heated shore tank. The right choice is set by what equipment exists at the receiving end.
The packing sets the tonnage, not the box. A 20-foot container takes 80 drums — ten along, four across, two tiers — so the load is 12 MT on a 150 kg fill, 14.4 MT at 180 kg and 14.8 MT at 185 kg. One-tonne bags stow ten down and ten on top: 20 bags, 20 MT. A tank container or bitutainer holds 20 to 25 MT with no packing at all. None of those loads approaches the plated payload of the container, so the figures that actually decide the fill are the two-tier stack limit and the road weight limit at destination.
It is an insulated tank built into a standard 20-foot ISO frame, fitted with a heating system and a bottom discharge outlet, carrying 20 to 25 MT. At destination the product is reheated using the unit's own heating system until it is pumpable, then discharged through the bottom outlet by pump or gravity into a heated receiving tank. Reheating a full cold unit is a matter of days rather than hours, so it must be started before the plant needs the binder.
It should. On a bulk vessel the cargo tanks are insulated and heated for the whole voyage, and discharge normally takes place in the 130–160 °C range, which is the practical pumping window for a paving grade. If cargo heating has failed or been reduced in transit, the parcel will discharge slowly and vessel demurrage starts to accrue. Ask for temperature records covering the voyage, not just a load-port figure.
Solid bitumen in drums or bags at ambient temperature is not normally treated as dangerous goods. Bitumen carried in a tank at or above 100 °C falls under the IMDG Code provisions for elevated-temperature substances and is declared accordingly. The distinction is the temperature at which it travels, not the product. Confirm the treatment with the carrier at booking, and have the Safety Data Sheet available in any case, since destination customs and terminals increasingly ask for it.
Product, packing, inland haulage at origin, terminal handling and stuffing, export documentation and inspection, ocean freight and its surcharges, marine insurance, destination terminal handling, import duty and taxes, inland delivery, and the cost of discharging and melting the product at your end. Any demurrage or detention sits on top. Comparing offers on product price alone is how buyers end up paying more for the cheaper tonne.
Ocean freight and freight surcharges above all, since rates and bunker, congestion or war-risk surcharges can move between booking and sailing. Product price moves with crude and heavy residue values, and packing tracks steel. Terminal handling, documentation and inspection are broadly fixed. Import duty is stable until a policy change moves it in a single step. Demurrage is the exception — high when it appears, and avoidable.
Cool the affected area with clean cold running water for at least 20 minutes. Never peel or solvent-strip bitumen that has adhered to the skin — removal is a clinical decision and the adhered layer is protecting the wound underneath. Get medical attention and take the Safety Data Sheet with the casualty. Handling hot binder is where most bitumen injuries occur, so brief the discharge crew before the cargo arrives, not on the day.
Send the grade, tonnage, packing preference, destination port and the Incoterm you want quoted, along with what you have at the receiving end — melter, tank, weighbridge or none of them. The offer will be built around the mode you can actually discharge.
