Learn morePAYMENT TERMS
For a first cross-border order with a new supplier, the most straightforward structures are cash against documents (CAD) and letter of credit at sight (LC at sight). Both give the buyer documentary control before funds are released while giving the supplier confirmed payment before the parcel is delivered. After a buyer has verified the company and certificates on a first order, we offer 50% pre-dispatch with the balance due before dispatch of the confirmed parcel. For small trial orders from an established contact, telegraphic transfer in advance removes the documentary overhead and is the simplest route for parcels under a defined value threshold.
Memo and consignment are not offered as a default. The stones are high-value and the dispute risk without a robust inspection protocol on both sides is significant. If a specific arrangement is required for your account structure, raise it in your enquiry and we will advise on what we can support.
SINGAPORE LANDED COST
Singapore levies 9% GST calculated on CIF value plus duties and incidental charges. Loose diamonds are not a dutiable category under Singapore Customs, so the applicable rate is 0% customs duty plus 9% import GST. A GST-registered Singapore buyer can typically claim the import GST as input tax, reducing the effective landed cost to the stone price plus logistics and clearance fees in most circumstances. Confirm your buyer's GST registration status and the applicable HS classification with a Singapore customs broker before the first shipment.
A Free Trade Zone or licensed Zero-GST warehouse can suspend GST while goods remain under the relevant scheme. GST becomes payable when goods are released for local circulation. This makes Singapore a practical logistics point for buyers consolidating stock for onward export, but it does not convert a domestic sale to a Singapore jeweller into a tax-free transaction.
