中国沥青进口单证 · Bitumen Import Documents for China

中国进口沥青的单证以报关单为核心，另需商业发票、装箱单、提单、原产地证、批次COA、中文SDS（GB/T 16483）和检验证书。2018年关检融合后，检验检疫职能并入海关总署，报关报检合并为一次申报。合同、信用证与报关单的品名、数量单位、商品编号和收货人必须一致，否则银行可拒付、海关可质疑申报。

A bitumen import into China is built around one legal instrument, the customs declaration (报关单), and a supporting file that has to agree with it line by line. The core set is the commercial invoice, the packing list, the bill of lading, the certificate of origin, the batch certificate of analysis, a safety data sheet in Simplified Chinese to GB/T 16483 format with GHS classification under the GB 30000 series, and — where the tariff line or the contract calls for one — an inspection certificate. Since the 2018 institutional reform the entry-exit inspection and quarantine function sits inside the General Administration of Customs (中国海关总署, GACC) and the customs and inspection declarations have been merged into a single filing, so guidance that still treats CIQ as a separate agency taking its own declaration is describing a process that no longer exists in that form. The expensive failures are not missing documents but inconsistent ones: the goods description, the quantity together with the unit it is expressed in, the commodity code and the identity of the consignee have to be identical across the sales contract, the letter of credit and the declaration, because a bank examining documents under UCP 600 and a customs officer examining a declaration against its supporting evidence are two independent readers, each able to stop the shipment for the same drafting error. What the file looks like also depends on how the cargo is packed: drummed and bagged bitumen is declared and credited in packing units, while a bulk parcel brings a charter party bill of lading, survey-based quantity figures and a tolerance argument that drums never have.

2018年关检融合 · The merger that ended the second filing

Until 2018 an import into China faced two authorities. Customs handled classification, valuation, duty and release. A separate entry-exit inspection and quarantine service — referred to in trade correspondence simply as CIQ — handled inspection and quarantine, took its own declaration on its own form, and issued its own certificates. Two filings, two clocks, two sets of paperwork to keep consistent with each other.

The institutional reform of 2018 transferred the entry-exit inspection and quarantine function into the General Administration of Customs (中国海关总署, GACC), and during the same year the customs declaration form and the inspection declaration form were merged into one. The trade calls it 关检融合, customs and inspection integration. The practical consequence for a document file is that there is one declaration, one authority reading it, and one set of regulatory condition codes attached to the tariff line that determines whether statutory inspection (法定检验) applies to that commodity.

Two wrong conclusions get drawn from this, and both cost money. The first is that CIQ still exists as a separate step — an agent who offers to obtain a separate CIQ certificate, or who builds a timeline around a second agency's clearance, is quoting a pre-2018 process, and that is a useful signal about how current the rest of their advice is. The second is that inspection went away. It did not. Sampling, documentary checks, quarantine controls and statutory inspection requirements all still exist; they are simply administered by customs now, and whether they reach a given cargo is signalled by the codes attached to the confirmed national commodity code rather than by the product name.

单一窗口 · Where the declaration is actually filed

Declarations are filed electronically through the China International Trade Single Window (中国国际贸易单一窗口), either by the consignee itself or by a licensed customs broker (报关企业) acting under a written brokerage authorisation (报关委托书). Nothing on the seller's side is filed into that system directly. What the seller controls is the quality of the inputs — the invoice, the packing list, the certificate of origin, the certificate of analysis, the safety data sheet — and every one of those becomes a data field that the declarant has to reconcile. A seller who treats the export documents as a formality is handing the buyer's broker a reconciliation problem and, eventually, handing themselves an amendment request.

报关单上的三个当事人 · The three parties named on the declaration

An import declaration names more than one company, and confusing them is one of the most common structural errors in this trade.

• 境内收发货人 — the domestic consignee of record. This is the Chinese entity registered with customs, identified by its unified social credit code, that makes the declaration in its own name and carries the legal responsibility for it. It must hold the filing that entitles it to import.
• 消费使用单位 — the unit that will actually consume or use the goods. For a trader importing on behalf of an asphalt producer these two are different companies, and the declaration says so.
• 申报单位 — the entity that physically files, normally the broker under the brokerage authorisation.

The consignee named on the bill of lading has to be reconcilable with the 境内收发货人 on the declaration, and the customs import VAT payment certificate is issued in the name of the declared consignee — which is what determines who can claim the input credit. Where the buyer intends to import through an agent, that structure has to be settled at contract stage, because it changes what the bill of lading should say and it changes who the letter of credit applicant is.

报关单的关键栏目 · The fields a seller's documents feed

The declaration is a structured form, and each field draws on a specific export document. The fields that generate queries in bitumen imports are these:

• 商品编号 · Commodity code. The full national commodity code, not the six-digit international subheading. Petroleum bitumen sits internationally in HS 2713.20 (石油沥青), but the code entered on the declaration is longer and carries the regulatory condition codes. It must be confirmed with a licensed broker against the current tariff schedule.
• 商品名称及规格型号 · Name and specification. Not just a product name — the field expects the specification or model as well. This is where the grade, the governing standard and the quality class belong, and it is the field that has to match the contract and the credit word for word.
• 数量及单位 · Quantity and unit. The declaration wants the quantity in the statutory unit attached to the tariff line (法定计量单位), which for petroleum bitumen is a weight unit — confirm the exact unit with the broker. A contract written in metric tonnes and a declaration written in kilograms have to reconcile arithmetically and exactly.
• 件数、包装种类、毛重、净重 · Packages, packing type, gross and net weight. Net weight for drummed cargo excludes the drum tare; gross weight includes the packing but not the container tare. These come straight off the packing list, which is why a sloppy packing list becomes a customs question.
• 成交方式、运费、保费、杂费 · Trade term, freight, insurance, other charges. The declared trade term drives how freight and insurance are entered, because the duty-paid value is built on a CIF-type basis. An invoice that is silent on freight under a CFR sale forces the declarant to guess.
• 原产国（地区）· Country of origin. Taken from the certificate of origin, not from the port of loading and not from the flag of the vessel.
• 集装箱号、唛头及备注 · Container numbers and shipping marks. Read against the packing list and the bill of lading. Marks that exist on the drums but not on the documents, or the reverse, are a straightforward examination finding.

None of these fields is filled in by the exporter. All of them are filled in from the exporter's documents. That is the whole argument for drafting the export set against the declaration rather than against habit.

批次COA · What a Chinese specification actually requires on the certificate

A certificate of analysis is a record of what was measured on the material that loaded. It is not a specification sheet with the supplier's name on it, and a certificate whose values land exactly on the specification limits shipment after shipment deserves the scrutiny it usually escapes.

Where the contract is written against a Chinese standard, the certificate has to speak that standard's language. Two standards govern road bitumen in China and buyers confuse them constantly:

• JTG F40-2004《公路沥青路面施工技术规范》 — the Ministry of Transport construction specification, which defines 道路石油沥青 in grades 160#, 130#, 110#, 90#, 70#, 50# and 30#, each subdivided into quality classes A, B and C.
• GB/T 15180《重交通道路石油沥青》 — the national standard for heavy-traffic road petroleum asphalt, using the AH- designations AH-130, AH-110, AH-90, AH-70, AH-50 and AH-30.

Naming the wrong one on the certificate is not a cosmetic error, because the limits differ. Under GB/T 15180 an AH-70 carries a softening point (软化点) band of 44–54 °C, a wax content (蜡含量) maximum of 3.0 %, solubility (溶解度) minimum 99.0 %, and after the thin film oven test a mass change within ±0.6 % and a retained penetration ratio of at least 61 %. Under JTG F40-2004 a 70# of class A carries a softening point minimum of 46 °C, solubility minimum 99.5 %, a wax content maximum of 2.2 %, and after ageing a mass change within ±0.8 % with retained penetration of at least 61 %. A certificate that says 70# and reports 99.2 % solubility is compliant against one standard and non-compliant against the other.

标号是名义针入度 · The grade number is a nominal penetration, not a band

This is the single most common misunderstanding in China-facing bitumen trade and it belongs on the certificate as much as in the contract. In the Chinese system the number with a hash is the nominal penetration, and the acceptance band sits either side of it: 70# covers penetration 60–80 (0.1mm), 90# covers 80–100, 50# covers 40–60. This is unlike ASTM 60/70, where the two numbers are the band. An ASTM 60/70 cargo normally falls inside the 70# penetration band, but the two names are making different claims, and a certificate that carries one while the credit calls for the other is inviting a reader to decide whether they match.

等级 A / B / C · Why penetration cannot evidence the class

The Chinese quality class has no ASTM equivalent and it is not set by penetration, which is identical across classes. It is set by the tighter limits on wax content (蜡含量), ductility at 10 °C (10 °C延度), penetration index (针入度指数) and the residue requirements after ageing. A级 is the highest class and is permitted for all grades and all pavement layers; B级 is permitted for the lower layers of expressways and class-1 highways and for all layers of lower-class roads; C级 is for class-2 highways and below.

The consequence for the certificate is direct. If the contract and the credit call for 70号A级, a certificate reporting penetration, softening point, flash point and solubility does not evidence the class at all. The lines that do are the class-linked ones: wax content by the distillation method, with a maximum of 2.2 % for A级, 3.0 % for B级 and 4.5 % for C级; ductility at 10 °C; penetration index within the range −1.5 to +1.0; and the ageing residue results. Omit them and the buyer's engineer is entitled to reject the class, whatever the grade number on the drum says.

蜡含量 · The line Middle East sellers must not leave blank

Be plain about this rather than working around it. Naphthenic crude produces naturally low-wax bitumen and is the domestic quality benchmark in China. Many Middle East crudes are more paraffinic and therefore give a higher wax content, and wax content is precisely the property the Chinese class system polices most tightly. This is the single biggest technical barrier for Middle East bitumen entering the Chinese market. The commercial answer is not to omit the line from the certificate; it is to test it, report the measured value, and let the buyer match the class to the value rather than discover the gap at the plant.

试验方法 · Which test methods the certificate should cite

Chinese testing follows JTG E20-2011《公路工程沥青及沥青混合料试验规程》: T 0604 penetration, T 0605 ductility, T 0606 softening point, T 0607 solubility, T 0611 flash point, T 0615 wax content by distillation, T 0609 thin film oven test, T 0610 rolling thin film oven test, T 0603 density and T 0620 dynamic viscosity. Where an export laboratory reports against ASTM methods, cite both and state that they are equivalent in intent, not identical in procedure. A certificate that names only a foreign method against a Chinese standard leaves the buyer's laboratory to decide whether the numbers are comparable, and that decision will not be made in the seller's favour once the cargo is discharged.

中文SDS · Format, not translation

The safety data sheet for the Chinese market follows GB/T 16483 format — sixteen sections in a prescribed order — with GHS classification under the GB 30000 series, and it must be in Simplified Chinese. Sending an English sheet with a Chinese cover page does not satisfy this. Neither does a machine translation that keeps a foreign section order. The safety data sheet is requested by terminals, by carriers, by the buyer's EHS function and, where the tariff line carries the relevant condition, in support of the declaration. The package itself is a separate requirement: chemical safety labelling in Chinese follows GB 15258, and drums that arrive marked only in English create a problem at unstuffing that no amount of correct paperwork solves.

One point belongs on the sheet rather than in a blanket claim: solid bitumen packed in drums or bags and shipped at ambient temperature is generally not handled as a dangerous good, whereas bitumen carried at or above 100 °C is UN 3257, Class 9. State the condition of carriage, and make sure the sheet, the booking and the transport document describe the same condition.

检验证书 · Independent inspection, and what it is worth

An inspection certificate covering quality, quantity and packing condition at the load port buys three things no supplier laboratory can provide: sampling drawn independently and spread across the cargo rather than from one accessible drum, sealed retained samples held by both parties, and a report from a name the buyer's bank, the buyer's engineer and any subsequent enquiry will already recognise. Where the credit calls for an inspection certificate it becomes a stipulated document and its wording is examined like any other, so the certificate's description of the goods has to match the credit as carefully as the invoice does. Separately, customs may sample and inspect on arrival under the statutory inspection regime; a load-port certificate does not displace that, but it gives both parties a traceable reference if the two results ever have to be argued.

三个读者 · Who is reading, and against what

• 合同 · The sales contract. Read by the parties, and by a tribunal if it ever gets that far. It defines what was actually sold — grade, governing standard and edition, quality class, packing, quantity basis, inspection arrangement and delivery term.
• 信用证 · The letter of credit. Read by the issuing and nominated banks against UCP 600. Banks deal with documents, not with goods: a credit is a separate transaction from the contract it arises out of, and the bank neither knows nor cares whether the bitumen is excellent. It examines whether the presentation appears on its face to comply, and it has a maximum of five banking days following presentation to decide. A presentation including original transport documents must be made no later than twenty-one calendar days after the shipment date, and in any event by the expiry date.
• 报关单 · The customs declaration. Read by GACC against the tariff schedule and against the supporting documents. Here the description is a legal statement about the contents of the container, tied to a commodity code and evidenced by the invoice, the packing list and the certificate of analysis.

The bank's test is more forgiving than most sellers assume in one respect and stricter in another. Data in a document need not be identical to data in another document or in the credit, but it must not conflict with it. The commercial invoice is the exception: its description of the goods must correspond with the description in the credit. Other documents may describe the goods in general terms, provided those terms do not conflict. So the invoice must track the credit closely, while the certificate of analysis and the bill of lading may be shorter — as long as nothing in them contradicts anything else.

1. 品名描述 · Description of goods

This is where the Chinese grading system does its damage. A contract saying Bitumen 60/70 while the buyer's project specification and the credit say 70号道路石油沥青A级 is not two ways of saying one thing. The Chinese name asserts a nominal penetration with a 60–80 band, a governing standard, and a quality class defined by wax content, ductility at 10 °C, penetration index and ageing residue. The ASTM name asserts a 60–70 penetration band and nothing else. A bank comparing an invoice that says one against a credit that says the other is entitled to call it a discrepancy, and a customs officer comparing the declared 商品名称及规格型号 against the certificate of analysis is entitled to ask which product actually arrived.

The fix is to name both, with the standard behind each, and then never paraphrase: Bitumen 60/70 to ASTM D946, supplied against 70号道路石油沥青 to JTG F40-2004, A级. Fix the exact string once, and reuse it verbatim in the contract, the credit application, the invoice, the packing list, the certificate of analysis and the declaration instruction. Also fix the vocabulary: asphalt, bitumen, 沥青 and 石油沥青 are not interchangeable, and drift between them can point a reader towards a different tariff heading altogether.

2. 数量与计量单位 · Quantity and the unit it is expressed in

Quantity discrepancies are more common than description discrepancies and are usually pure arithmetic. Three traps recur:

• The unit changes between documents. The contract is in metric tonnes, the packing list is in kilograms, the declaration is in the statutory unit for the tariff line, and somewhere in that chain a rounding appears. Reconcile the conversions exactly and state both figures where it helps.
• Net and gross are not distinguished. For drummed cargo the invoiced quantity should be net of drum tare, and the contract should say so explicitly. The declaration then carries the net weight excluding tare and the gross weight including the packing but not the container.
• Tolerance is assumed where none exists. Under UCP 600 a tolerance not exceeding 5 % more or less than the quantity is available only where the credit does not state the quantity in a stipulated number of packing units or individual items, and the drawing does not exceed the credit amount. A credit reading 1,600 drums of 180 kg net states packing units, so there is no 5 % tolerance — 1,598 drums is short shipment. A credit reading 288 MT in bulk generally has the tolerance. Where the words about or approximately are used in relation to the quantity, the allowance is 10 % more or less.

3. 商品编号 · The HS subheading

Petroleum bitumen sits internationally in HS 2713.20 (石油沥青), but the six digits are the international part of the code; the number entered on the declaration is the longer national commodity code with its attached regulatory condition codes, and only a licensed broker working from the current tariff schedule can confirm it.

The consistency problem is that a code can appear in several documents at once. Some Chinese buyers ask for the commodity code on the invoice. The certificate of origin has its own HS column. The declaration carries the operative national code. If those disagree, two independent things happen: the bank sees conflicting data across stipulated documents, and customs sees a certificate of origin that does not support the tariff line being claimed, which puts any preferential rate in question. The safe practice is to agree the six-digit classification with the broker before documents are issued, keep every document consistent at that level, and put no national code on a seller-issued document unless the broker has confirmed it in writing.

4. 收货人 · Consignee details

The consignee question is really three questions that have to be answered together, ideally at contract stage.

• Who is consignee on the bill of lading? Under a credit the bill is often made out to the order of the issuing bank or to order and blank endorsed. That is a financing decision with an operational tail: if the bill is to the order of the bank, no delivery order will be issued until the bank endorses and releases the documents, and if the vessel beats the documents the container sits accruing demurrage.
• Who is 境内收发货人 on the declaration? The Chinese entity registered with customs that declares in its own name. If the buyer imports through an agent, the consignee of record may not be the company that ordered the cargo.
• Whose name goes on the import VAT payment certificate? It follows the declared consignee, and it is the instrument the Chinese buyer needs to claim the import VAT as an input credit. A buyer who loses that credit because the paperwork named the wrong entity will come back to the contract looking to recover it.

There is also a documentary trap worth knowing. Under UCP 600 the addresses of the applicant and beneficiary need not be identical to those in the credit, provided they are in the same country as the addresses stated there — but when the applicant's address and contact details appear as part of the consignee or notify party details on a transport document, they must be exactly as stated in the credit. So a bill of lading that abbreviates the buyer's registered Chinese address in the notify field is a discrepancy even though the same abbreviation would be harmless anywhere else on the document.

后果链 · What one inconsistency actually costs

Follow a single mismatch through and it lands in four places. At the bank, documents can be refused; the bank gives a single notice stating every discrepancy it is relying on, and it is then precluded from raising others, so the seller either corrects and re-presents inside the remaining time or asks the buyer to waive. The moment a waiver is needed, commercial leverage moves to the buyer, and on a falling market that is not theoretical. Discrepancy handling charges are deducted regardless of outcome. At customs, a declaration inconsistent with its supporting documents can be queried and the shipment stops while it is resolved; amending or cancelling a filed declaration is a formal procedure requiring approval, not a correction the declarant can simply make, and the enquiry consumes the statutory declaration clock. At the port, container demurrage and terminal storage accrue daily and are indifferent to fault; drummed cargo sitting uncovered through a wet season is also a condition risk, not only a cost. In the buyer's tax position, a fix that changes the declared value or the party of record can move the VAT payment certificate away from the entity that expected the credit.

All four are produced by the same root cause: someone improved the wording in one document. A description that is slightly clumsy in six identical copies clears. A description that is elegant in six different versions does not.
