I just started working in this fieldOn the invoice, what should be filled in the "S/C No." column? Is it the same as our sales contract number? Will filling it incorrectly affect the client's payment and customs clearance?

Customs Declaration & Compliance ExpertStart a Chat
S/C No. is an abbreviation for Sales Contract Number. From a compliance perspective，this number serves as one of the crucial bases for customs to verify the authenticity of trade transactions. You must ensure that this number is fully consistent across commercial invoices，customs declarations，and accompanying contracts. For goods subject to license management，the S/C No. must also correspond to the contract number on the license，otherwise the declaration will be rejected. Special note: During customs inspections，this number serves as a key index for tracking the entire set of transaction documents. It is recommended that you establish strict numbering rules and archive and preserve these documents for at least five years.

The S/C No. is the "primary key" of your entire logistics chain. At the operational level, this number must appear on all main documents such as commercial invoices, packing lists, bills of lading, and customs declarations. Freight forwarders and customs brokers rely on it to link documents. For EXW or FOB terms, clients may provide their own purchase order numbers as S/C Nos. You must confirm in advance which number to use to avoid document mismatches. The most direct consequence of filling in the wrong number is customs system rejection or inspection, which delays the shipping schedule. Tip: You can print the S/C No. on the outer box labels to facilitate quick identification at the destination port.

S/C No. is essentially the "ID number" of your order. In business communication, it is recommended that you consistently use this number in all aspects such as email subject lines, contract headers, payment water bills, etc. This will demonstrate your utmost professionalism. Particularly in letter of credit settlements, the S/C No. must appear strictly on all negotiable documents, as banks will verify every detail during document review. If the client requests to modify the contract number, you need to assess whether this will affect the already submitted bank documents. A practical phrase: "To ensure smooth payment and customs clearance, please refer to S/C No. XXX in all subsequent communications. Thank you for your cooperation!" This can effectively avoid the confusion caused by clients arbitrarily changing the number.
