A Japan IOR shipment stalls at customs almost always because the documents presented under the letter of credit, the commercial invoice, the packing list and the bill of lading, name a different buyer, consignee or value than the entity filed on the Import Declaration (輸入申告). Paying by letter of credit (L/C) does not change who Japan Customs treats as the importer, and it does not change how customs value is calculated. A document mismatch does both.
Does Paying by Letter of Credit Change Who Is the Importer of Record in Japan?#
Paying by L/C does not change who is named on the Import Declaration. That determination runs on a separate question entirely: whether Aplash buys the goods and takes title before filing, as Importer of Record (IOR), or whether the non-resident client remains the legal importer and Aplash acts as its procedural agent, Attorney for Customs Procedures (税関事務管理人), under Customs Act (関税法) Article 95. An L/C is a bank-to-bank payment instrument sitting on top of whichever structure already applies; it has no bearing on which entity that structure names.
This is the same confusion that shows up around Incoterms, and the answer runs the same direction. Incoterms do not decide who Japan's importer of record is either: DDP, FOB and EXW describe who arranges carriage and who bears risk of loss in transit, not who is legally the importer under Japanese customs law. An L/C adds a third layer on top, a payment guarantee between the buyer's bank and the seller's bank, and it is autonomous from the underlying sale contract. Under UCP 600 (ICC Publication No. 600, effective July 1, 2007, incorporating eUCP v2.0 from 2019), the bank pays against conforming documents regardless of the condition the goods actually arrive in. The bank's 39 articles govern the payment relationship between banks and sellers. None of them touch the customs relationship between an importer and Japan Customs.
How Does an L/C Affect Which Documents Japan Customs Sees?#
An L/C does not add a new document set for customs; it adds a second reader of the same documents, checking them against a different standard. The commercial invoice, packing list and bill of lading that accompany a shipment under L/C are the same documents Japan Customs reviews at the Import Declaration. The difference is what each reader is looking for.
The issuing or confirming bank examines the documents on their face, within a maximum period of 5 banking days from presentation, to confirm they comply with the L/C's own terms: correct quantities, correct value, correct named parties, shipment within the stated window. Japan Customs separately examines the same invoice and packing list, plus the Import Declaration itself, to confirm the declared value and the declared importer match what was actually shipped and who is actually taking title. A document can pass the bank's compliance check and still draw a customs query, because the two checks are not testing the same thing. The named buyer or consignee on the L/C and the commercial invoice has to match the IOR entity on file, or the non-resident client named under the ACP appointment. If the L/C names the overseas buyer's own trading name while the Import Declaration carries Aplash's corporate name as IOR, or the client's registered name under ACP, that mismatch is what stops the file, not the fact that payment ran through an L/C at all.
Why Do L/C Document Discrepancies Cause Customs Clearance Delays?#
Discrepancies between the L/C, the commercial invoice, the packing list and the bill of lading are the most common cause of payment delay under L/C, and separately, the most common cause of a customs valuation query when those same documents do not match the IOR or ACP entity on file. A bank deals in documents, not goods, so a misspelled consignee name, an inconsistent gross weight between the packing list and the bill of lading, or a shipment date that falls outside the L/C's stated window is enough to trigger a discrepancy notice and hold payment. The same inconsistency, read by Japan Customs instead of a bank, reads as a question about who the actual importer is or whether the declared value reflects the real transaction.
These are two separate clocks. The bank's examination runs 5 banking days from presentation and only governs when the seller gets paid. Customs clearance has no equivalent fixed window; a query can sit open until the importer or its agent resolves it. A shipment can clear customs cleanly while the L/C payment is still in dispute over the same discrepancy, or the reverse: payment can go through on the bank's side while customs holds the goods over a named-party mismatch the bank never checked for.
Does the L/C Say CIF or FOB, and Why Does That Matter for Customs Value?#
Japan customs value is calculated on a CIF basis, so whether the L/C and commercial invoice specify CIF or FOB terms directly affects the declared dutiable value. Where the L/C states FOB, the freight and insurance cost have to be documented separately and added to the FOB figure to arrive at the CIF value that goes on the Import Declaration. Where the commercial invoice presented to the bank shows a different basis than the one presented to customs, without a reconciling freight and insurance line, the declared value itself becomes the subject of the customs query rather than the payment.
This connects directly to two other points that cause valuation disputes independent of the L/C. Exchange rate movement between invoice date and declaration date changes the yen value customs assesses duty against, even when the underlying L/C amount in foreign currency never changes, so a shipment invoiced weeks before shipment and paid under L/C on arrival can show a different declared value than the figure the buyer expected when the L/C was opened. And where the CIF figure depends on an insurance premium, cargo insurance coverage and who holds it during the import needs to be documented with the same specificity as the freight line, because an unsupported insurance figure inside a CIF declaration invites the same query as an unsupported freight figure. For the mechanics of how a CIF declaration is built in the first place, see how to declare import value correctly in Japan.
Before a shipment goes out under L/C, a short set of checks against the Import Declaration avoids most of the delay described above.
(a) The buyer or consignee name on the commercial invoice, packing list, bill of lading and L/C matches, exactly, the entity that will be filed on the Import Declaration, whether that is the IOR entity or the non-resident client under ACP.
(b) The Incoterm stated in the L/C and the commercial invoice matches the Incoterm actually used to compute the declared customs value, which in Japan is always converted to a CIF basis regardless of what term the sale contract uses.
(c) Where the L/C is on FOB terms, freight and insurance costs are documented as separate, supportable line items so they can be added to reach the CIF figure customs expects.
(d) Any inspection certificate, certificate of origin or other document the L/C requires is also available to customs on request, since the bank's document set and customs' document set overlap but are not identical.
(e) The commercial invoice value and currency match what was actually negotiated under the L/C, so a mismatch is not introduced by a rounding or conversion step between the two presentations.
Getting this right before the goods ship is a document-coordination exercise, but it sits squarely inside the scope of an IOR or ACP engagement. Aplash structures the import so the Import Declaration carries the correct named party from the outset and reviews the shipping document set against that structure before the goods move, which is the point at which an L/C-driven mismatch is still cheap to fix. Review of the IOR and ACP structures themselves is the right starting point when the named-party question is still open.
Frequently Asked Questions#
If Japan Customs holds my shipment for a valuation query, does that also delay my L/C payment?
Not automatically. The bank's examination period runs from presentation of documents to the bank, and is capped at 5 banking days under UCP 600, independent of how long the goods sit with customs. Where the underlying discrepancy, a named-party mismatch or an unsupported CIF figure, affects both document sets, the two delays tend to surface together, but a clean customs clearance does not guarantee the bank finds the documents compliant, and a compliant presentation to the bank does not guarantee customs releases the goods without a query.
Can I use ACP if the L/C names my own company as consignee?
The L/C naming your company as consignee has no bearing on ACP eligibility. ACP is available where your company has no address, residence or office in Japan, which is the Customs Act Article 95 non-residence requirement; the consignee name on the L/C only matters insofar as it needs to match the name actually filed on the Import Declaration once that structure is set. If your company already has a registered Japan presence, ACP is not the available structure regardless of how the L/C is worded.
Who is responsible for correcting a document discrepancy, the bank or the customs broker?
They correct different things. A discrepancy flagged by the bank, under the L/C's own compliance terms, is corrected between the seller and the issuing or confirming bank, and is a trade finance matter outside the customs file. A discrepancy that affects the Import Declaration, a named-party or valuation mismatch, is corrected through the customs broker handling the declaration, working from the same underlying documents. The two corrections can overlap in substance without being the same process.
Does Aplash negotiate with the issuing or confirming bank directly?
Aplash's role sits on the customs side of the transaction: structuring the IOR or ACP arrangement so the Import Declaration carries the correct named party, and reviewing the commercial invoice, packing list and bill of lading against that structure before the goods move so a document-set mismatch does not surface as a customs query after the fact. The L/C relationship itself runs between the buyer, the seller and their respective banks.
