沥青运往中国的海运方案 · The Sea Leg to China: Routing, Timing and Incoterms

沥青运往中国的航线从中东装港出发，经阿拉伯海、印度洋、马六甲与新加坡海峡进入南海，先抵华南，再沿海北上至华东与北方。越往北航程越长，而施工季越短，排期余量最小的区域恰在最长航段的末端。集装箱货应使用FCA、CPT、CIP，风险在交付承运人时转移；FOB、CFR、CIF是为装船的散装货写的。按2020年通则，CIF只需最低险，CIP须投一切险。热带航段的高温与结露改变的是货物状态而非组分，滞期费则几乎都由单证时点造成。

A China-bound bitumen cargo leaves a Middle East load port, runs out of the Gulf and across the Arabian Sea and Indian Ocean, passes the Malacca and Singapore Straits into the South China Sea, and then works its way up the Chinese coast. The south is the first landfall, the Yangtze delta adds a coastwise leg, and the northern ports add more still — so the sea leg lengthens northward exactly as the usable construction season shortens northward. For containerised cargo the correct Incoterms 2020 rules are FCA, CPT and CIP, because risk passes at handover to the carrier rather than on board the vessel; FOB, CFR and CIF are the sea and inland waterway rules, written for bulk parcels the seller loads himself. Under Incoterms 2020 the CIF insurance obligation is minimum cover while CIP is all-risks. The tropical crossing changes the condition of packed cargo — drum deformation, bag consolidation, condensation — but not its composition, and demurrage at a Chinese terminal is caused on land, by documents, on a clock the sea leg started.

From a Middle East load port the voyage is one long line. The vessel leaves the Gulf through the Strait of Hormuz, crosses the Arabian Sea and the northern Indian Ocean, passes through the Malacca and Singapore Straits, enters the South China Sea and makes its first Chinese landfall in the south. From there the coast runs northeast: the Pearl River delta and the wider Guangdong coast, then the Yangtze delta, then the Bohai Rim and the northeastern gateway beyond it. Nothing about this route is optional or clever. It is the trunk route, and a bitumen cargo shares it with everything else moving between the two regions.

The consequence is that Chinese discharge points are not interchangeable in schedule terms even when they are interchangeable commercially. The southern coast is the nearest, the delta adds a coastwise leg, and a northern discharge adds more again. Freight quotations tend to flatten this into a single line item, which is why the geography is worth holding in mind separately from the rate.

倒挂的地方 · The inversion that makes northern shipments a planning problem

Here is the point this page exists to make, and it is a structural one rather than an operational one. The sea leg gets longer as you go north. The usable paving season gets shorter as you go north. Those two facts move in opposite directions along the same coastline, and they meet at the worst possible place: the region with the least tolerance for a late arrival is the region at the end of the longest voyage.

In the far south there is no closed season to miss, so a late arrival costs money and inconvenience. In the northeast the season is the shortest on the coast, and a cargo landing after it has closed is late by a season rather than by days. The ports and terminals page sets out region by region what the cargo does once it lands and when each season opens and closes, and the climate zone page covers how the same geography drives grade selection. What belongs here is the routing consequence, and it is the part that gets missed.

Because northern buyers position material ahead of the opening rather than drawing it against demand as it appears, the northern arrival window is not only short, it is crowded. Everyone on that coast wants the same weeks. That is precisely when space on the services and connections feeding the north is least elastic, when a rolled booking is most expensive, and when a missed relay is least likely to find a quick alternative. The asymmetry is worth stating in one line: a southern shipment that misses a sailing waits for the next one, while a northern shipment that misses a sailing has to compete for it. A schedule built for the north therefore needs slack for a reason that has nothing to do with the weather at the destination.

直达还是中转 · Direct call or relay, and why the distinction is not cosmetic

A great many Middle East origins have no direct service to the specific Chinese port a buyer wants. The box is relayed at a hub instead: discharged, held in a yard, and loaded onto a connecting vessel. A quoted transit time frequently describes the trunk leg and treats the relay as though it were a moment rather than a stage.

It is not a moment. A transhipment introduces a second discharge, a yard dwell whose length depends on the connection frequency, a second loading, and a second vessel whose schedule was never the one you were shown. A missed connection does not add hours; it adds the interval to the next sailing on that connection, which on a thin service can be substantial. A coastwise or feeder leg to a smaller discharge port is the same thing again, with its own cut-offs.

The practical instruction is short. Before comparing two freight offers on transit time, ask which named service each one uses, what its rotation is, and how many relays the box goes through. Two offers with the same headline number can describe a direct call and a double relay, and those are not the same shipment.

货物形态跟着航段走 · The voyage argues for one cargo form over another

The sea leg has an opinion about packing, and it is worth stating separately from the receiving end's opinion. Packed cargo — new steel drums, jumbo or poly bags, or a bitutainer — travels cold and solid, is counted rather than gauged, stores through a closed season and is indifferent to a slow relay in schedule terms. Hot bulk in a heated tanker has to stay hot for the entire voyage, which means the sea leg is a heating period and a longer transit is a longer heating period. That distinction runs through the rest of this page: for packed cargo, transit time is a cost; for hot bulk, transit time is a specification variable.

Incoterms 2020 contains eleven rules in two families. Seven — EXW, FCA, CPT, CIP, DAP, DPU and DDP — are for any mode or modes of transport. Four — FAS, FOB, CFR and CIF — are the rules for sea and inland waterway transport, written for cargo the seller himself places on board a named vessel. FOB, CFR and CIF fit a bulk parcel pumped hot into a tanker, where the seller controls the cargo right up to the moment it crosses into the ship and delivery and loss of control are the same moment. For containerised cargo the correct rules are FCA, CPT and CIP, because a sealed box is handed to the carrier or the terminal days before it is loaded, and risk should pass at that handover rather than at the ship. They map one for one: FCA for FOB, CPT for CFR, CIP for CIF. The containerised shipment page argues that case at length and the Incoterms page works through all eleven rules and the cost allocation. Everything below is about what the choice then does to a China voyage in particular.

一、谁订舱，谁就定了免箱期 · The rule decides who negotiates the free time, and it is rarely the party who ends up paying for it

This is the link between the Incoterm and the demurrage section further down, and on this lane it is where the money goes. Under FCA and FOB the buyer contracts the carriage, so the free time at the Chinese terminal is a term in the buyer's own booking. Under CPT, CIP, CFR and CIF the seller contracts the carriage — and the free time in that booking is a term the seller agreed, at a terminal where the buyer will be the one watching the clock. A seller optimising a freight rate has no reason to buy free time he will never use, and no way of knowing how long the buyer's clearance and inland leg will actually take. The remedy is not a different Incoterm. It is a line in the sale contract stating the minimum free time the seller must obtain, agreed while the booking is still being placed, because once the box is on the ground in a Chinese terminal nobody is negotiating anything at all. Sold CIP or CPT, ask what free time is in the booking before the vessel sails. Sold FCA, remember that you were the one who bought it.

二、中转是卖方选的，风险却在买方 · Under CPT and CIP the seller picks the routing and the buyer carries it

Now read the two halves of CPT and CIP together against the relay problem described above. Risk passes at handover to the first carrier, at origin. Carriage is contracted and paid by the seller, all the way to the named destination. So the seller chooses the service, the hub and the number of transhipments — while every hour the box spends in a relay yard, and every consequence of a missed connection, falls on the buyer's side of the risk line. That is the deliberate design of the rules rather than a defect in them, but the consequence is concrete: a buyer on CPT or CIP terms who never asked which service the cargo was booked on has delegated a routing decision that he, and not the seller, is exposed to. Ask for the named service and its rotation at contract stage, not when the cargo is somewhere it should not be.

三、CIF与CIP的保险不是同一份 · The insurance is where the mapping breaks

CIP is not CIF with a different label, and this is one of the most consequential differences in Incoterms 2020. Under CIF the seller's insurance obligation is minimum cover — Institute Cargo Clauses (C) or a similar named-perils wording. Under CIP the obligation is all-risks cover, Institute Cargo Clauses (A) or similar. Both require the policy to be for at least 110 % of the contract price, in the currency of the contract, and to allow the buyer to claim directly. Set that against the damage this particular route produces: drums deformed under stack load after weeks in the equatorial band, seams and closures opened, water ingress from condensation, handling damage in a relay yard. A named-perils policy responds to a list of events; an all-risks wording responds to the loss. A buyer who accepts CIF on a containerised China shipment has taken the wrong transfer point and the narrower policy in the same three letters. Either party may agree wider cover than the rule obliges, but it has to be written in, because what the rule obliges is what applies by default.

四、保险的时间边界 · Where the cover stops, which on a Chinese inland leg is a real question

An Incoterm obliges the seller to insure. It says nothing about the policy lasting as long as the cargo journey does, and that gap is worth opening on a China shipment specifically. The Institute Cargo Clauses transit clause runs cover on a warehouse-to-warehouse basis but terminates it at whichever comes first of delivery at the named destination and the expiry of a stated period after discharge from the overseas vessel. Now set that against the two delays this page keeps describing — a container held through a clearance query and a yard dwell, and an inland leg that in this market can run deep into a provincial hinterland. It is entirely possible for a cargo to be uninsured through the last and roughest part of its journey while both parties assume that CIP is still working. The terminating events and the period are in the policy wording rather than in the three letters on the invoice, so the thing to read is the policy that was actually issued.

五、FCA、提单与时间 · Why the on-board bill of lading question is a scheduling question here

Sellers resisted FCA for one concrete documentary reason. A documentary credit normally calls for an on-board bill of lading, which can only be issued once the cargo is loaded — and under FCA that is after delivery has already taken place, so the seller had performed but could not obtain the document the bank required. Incoterms 2020 supplies an optional mechanism: the parties may agree that the buyer instructs the carrier to issue an on-board bill of lading to the seller once the goods are loaded. It is optional, it has to be written into the sale contract and reflected in the credit, and it depends on the carrier being willing to issue on those instructions; the containerised shipment page sets out how the provision works. The reason it appears on a page about the sea leg is timing rather than law. On a lane where the voyage can outrun the documentary chain, any term that inserts an extra step between loading and the issue of the bill of lading is a term that eats the margin before free time starts running at the other end. Decide it at contract stage and the margin stays; discover it at loading and it does not.

六、DDP进中国 · A term to be careful with

DDP makes the seller responsible for import clearance in the destination country, which for China means being the party that files the declaration and carries the import VAT position at 13 %. A foreign seller with no registered presence generally cannot do this, and an arrangement improvised through a third party is a risk the buyer inherits without ever seeing it. Unless there is a genuine, named structure behind it, DDP into China is a term to decline rather than to price. The HS code and clearance page covers what the importer of record actually has to do.

写法 · How to write it

Name the rule, name the place precisely enough that a reader could stand in it, and name the edition: CIF China is not a term of sale, while CIF [named discharge port], Incoterms 2020 is. Then check the two things this page has added to the standard advice — what free time the carriage contract obtains, and where the insurance cover ends relative to the inland leg — and check that the rule still matches the cargo form actually booked, because a contract that begins as drums and converts to bulk has quietly changed which family of rules it belongs to.

The route to China is a hot route for a defined portion of its length, and that portion is the part worth planning around. From the Arabian Sea the track runs down toward the equator and the box stays in that band through the northern Indian Ocean, the Malacca and Singapore Straits and the lower South China Sea, before the coast turns northeast and the air cools. Thermal exposure on this lane is therefore not really a property of the cargo or of the packing at all. It is a property of how many days the box spends in that band, where it is stowed while it is there, and how long it stands still in the middle of it — and of those three, only the third is decided by anything a shipper chooses.

最热的一段是中转堆场，不是船上 · The relay yard, not the ocean leg, is the peak exposure

A container at sea is in a stack, shaded on several sides, in moving air, over water. A container in a transhipment yard is standing on concrete, in still air, frequently with no shade at all — and the hubs that serve this route sit close to the equator. The stage of the voyage with the highest thermal load is usually not the ocean leg. It is the dwell in the relay yard: the stage whose duration nobody quoted, which does not appear in a port-to-port transit time, and which lengthens by a full sailing interval rather than by a few hours when a connection is missed.

That has a consequence worth stating plainly, because it is not obvious from a freight comparison. A routing decision taken purely on rate is a thermal decision taken by accident. Two offers with the same headline transit time, one direct and one double-relayed, expose the cargo very differently even though the paperwork treats them as equivalent. Where the cargo is packed material bound for a receiver who needs discrete units at the melter, a direct call can be worth paying for on grounds that have nothing to do with speed.

The second variable is the stow, and nobody controls it. A box on an exposed top tier in direct sun sees far more heat than one below deck. Under-deck stowage can be requested and noted on the booking; it cannot be guaranteed, which is a reason to pack for the worst case rather than for the requested one.

不会发生的事 · What the heat does not do

Bitumen does not run out of a drum at these temperatures, and it is worth saying so before describing what does go wrong, because the alarmed version of this story circulates widely. Under JTG F40-2004 the softening point requirement for 70# is a minimum of 46 °C for A级, and for 50# a minimum of 49 °C for A级. Softening point is a consistency reference point, not a melting point — the binder becomes progressively soft and deformable long before it is anything like liquid. Nor does the heat of a voyage meaningfully age packed bitumen: oxidative ageing is driven by the temperatures of plant mixing and hot storage, which are in an entirely different range. A tropical crossing changes the condition of packed cargo, not its composition.

决定损害的是时长与昼夜循环，不是峰值温度 · Duration and cycling do the damage, not the peak

What arrives damaged is the product of exposure multiplied by time, and of the day-night cycle repeated. Three things follow from that, and a longer or more heavily relayed routing does not add new ones — it simply adds repetitions.

• Drums deform. A drum holds its shape partly because its contents are stiff; soften the contents and the lower tiers are carrying the stack. Bulging at the chime, slumping out of round and stressed closures and seams are the result. None of it is a specification failure and most of it is not a product loss, but deformed drums are slow to de-stuff, they generate condition claims, and they are what a receiving surveyor photographs.
• Bags consolidate. Bags do not deform, they merge. Pressed together under stack load in a hot box, twenty discrete one-tonne units can arrive as one mass that no longer separates. The certificate is untouched; the problem lands entirely at the melter, and therefore in the receiving-end stage of the schedule set out above.
• The box rains on its own cargo. Moisture already inside evaporates through the hot day, condenses on the cold steel roof at night and drips back down. Over weeks that rusts drum seams and closures and wets bag surfaces, and where a closure has already been stressed it opens a path into the product.

Only one of those three is measurable on a certificate, and it is the last: water content by ASTM D95 is limited to a maximum of 0.2 vol % on a typical export specification, and free water in a drum causes foaming and a genuine safety hazard when the material is heated at destination. The controls for all three belong at origin and to the packing decision rather than to the voyage — the drummed cargo page covers fill, ullage, closures and why reconditioned drums fail this test, and the containerised shipment page covers load distribution, securing and stack height inside the box. What this page adds is the reason to take those decisions differently for a long, relayed, equatorial routing than for a short direct one, and the point in the process at which the routing is still changeable.

散装的情况正好相反 · For hot bulk, the voyage is not exposure — it is the ageing

Everything above concerns cargo that travels cold. A bulk parcel travels hot by design, and that inverts the analysis. The binder is held at temperature from the load port to the shore tank, so the sea leg is a heating period and a longer voyage is a longer heating period. That is oxidative ageing, and the Chinese acceptance table records it: mass change after RTFOT or TFOT must stay within ±0.8 %, and the retained penetration ratio must be at least 61 % for 70# A级. A binder that arrives already part-aged has spent some of its service life on the water.

Two consequences follow for a bulk shipment that do not apply to a packed one. Transit time becomes a technical variable to be discussed with the specification, not only a commercial one to be discussed with the freight. And the carriage condition sets the regulatory status: bitumen carried at or above 100 °C is UN 3257, Class 9, elevated temperature liquid, which changes the transport document, the marking and which carriers will accept it. Solid packed bitumen is generally not handled as a dangerous good. Neither blanket claim — always dangerous, never dangerous — survives contact with a real booking. The bulk cargo page covers the form itself.

海运不改变的东西 · The one thing the voyage cannot touch

Routing, stowage, transit time and packing all act on the condition of the cargo. None of them acts on its composition. Wax content is set by the crude slate, and JTG F40-2004 caps it by the distillation method T 0615 at 2.2 % for A级, 3.0 % for B级 and 4.5 % for C级. If a cargo is going to fail a Chinese acceptance test on wax, it was going to fail before it was loaded, and choosing a shorter route or a cooler stow does nothing whatever about it. That is a load-port problem and it is solved at the load port, or it is not solved at all.

三笔费用，三个时钟 · Three charges, three different clocks

Three charges get called by one name. 滞期费 demurrage is charged by the carrier while the box remains inside the terminal beyond free time. 滞箱费 detention is charged by the carrier once it has left the terminal and has not yet come back as an empty. 堆存费 terminal storage is charged by the terminal itself for the yard space it occupies — it is additional to the carrier's demurrage and it is not covered by free time negotiated with the carrier, so a shipper who negotiated generously on one and never asked about the other has solved half the problem. The logistics page covers how these charges are structured generally. Bulk runs on a different mechanism again: laytime and demurrage arise under the charterparty as a daily rate on the vessel from the tendering of notice of readiness, governed by the charterparty rather than the bill of lading, and the sums are not comparable. What follows is the part specific to this lane — not what the charges are, but why the clock starts at all.

免箱期是订舱时谈的，之后再也谈不了 · Free time is negotiated at booking, and never afterwards

This is the single most useful sentence in this section. Free time is a commercial term agreed when the booking is placed, at a moment when the carrier wants the cargo and the shipper has alternatives. Once the box is on the ground in a Chinese terminal with a clock running, the shipper has no alternatives at all and the carrier knows it. Free time accepted as offered, without being checked against the buyer's realistic clearance and inland time, is a term agreed by somebody who was not going to pay for it — which, as the Incoterms section above sets out, is exactly the position on CPT, CIP, CFR and CIF terms, where the seller places the booking and the buyer watches the clock. On those terms the free time has to be fixed in the sale contract, because by the time it matters the two parties are on opposite sides of an ocean.

为什么滞期几乎总是单证造成的 · Why the cause is nearly always a document

Demurrage is charged for time, so it feels like a transport problem. It very seldom is. The cargo arrived; that part worked. What failed is on land, and it is usually paper.

This trade lane has a structural trap that deserves stating on its own. The voyage from a Middle East load port to southern China can be completed faster than a documentary chain can be. A bill of lading has to be issued, couriered to a bank, examined, released against payment or acceptance, and couriered onward to the buyer — and each of those steps has its own calendar. The vessel does not wait for any of them. The result is a cargo on the ground with no document to release it against, free time expiring, and nobody having done anything wrong except plan the two chains independently of each other.

The fixes are known and each has a cost:

• Telex release, or surrender of the originals at origin, so that release at destination does not depend on a courier.
• A sea waybill, where no document of title is needed. This is clean and fast — but a sea waybill cannot satisfy a documentary credit that calls for a bill of lading, so choosing it is a decision about the payment structure rather than about the shipping document.
• An electronic bill of lading, where the carrier and both banks support the platform in question. Support is not universal and has to be confirmed rather than assumed.
• Presenting a clean set first time. Under UCP 600 a bank has up to five banking days following presentation to examine the documents. A discrepancy sends the set back and starts another cycle, and two cycles can consume more time than the ocean leg had left.

一致性 · Consistency is the other half of it

The second family of causes is not late paperwork but inconsistent paperwork. Every document in the set has to describe the same cargo in the same words: goods description, HS heading 2713.20 and its full national subheading, net and gross weights, marks and numbers, and the piece count. A packing list showing 80 drums against a bill of lading showing something else is not a typographical matter at a border; it is a query, and a query is dwell.

That consistency is cheap to check at the load port and expensive to establish afterwards, and the standard loading configurations to check it against — how many units and what net weight belong in a 20-foot box for each packing — are set out on the containerised shipment page. Two things in particular are worth confirming against them before the box is sealed: that the piece count on the packing list is the count that actually went in, and that the drum tare is excluded from the invoiced net weight, because a net weight that quietly includes steel is a discrepancy sitting in the file waiting for a customs officer to find it.

三件在装船前就该完成的事 · Three things to finish before the vessel sails

First, the safety data sheet: a Chinese-market document in GB/T 16483 format with GHS classification under the GB 30000 series, in Simplified Chinese. It is a slow thing to produce properly and an impossible thing to produce quickly once a query has already been raised against a consignment sitting in a yard. The SDS page sets out the format.

Second, the consignee's status. The named consignee has to be a party actually able to file the declaration and act as importer. This is checked before the booking, not discovered at the berth.

Third, the full document set, assembled and cross-checked as a set rather than as a pile. The import documents page lists what belongs in it. Every hour spent on that at origin is bought at the price of an hour; the same hour spent at destination is bought at the price of demurrage, storage and detention running in parallel.
