Your proposed transaction structure, "Bill to: Overseas Client / Ship to: Indian Customer" with machinery supplied within India and payment received in foreign currency is generally permissible under FEMA, RBI, Customs, and GST laws, subject to proper documentation and compliance.
FEMA / RBI
Under FEMA, receipt of foreign currency from a non-resident against supply of goods in India is permitted if supported by a genuine commercial contract/PO and routed through normal banking channels. Since goods are delivered within India, the transaction is not treated as a physical export under FEMA export regulations.
Key requirements:
Overseas party must be the contractual buyer.
Indian entity must be shown as consignee/end user.
Invoice may be raised in foreign currency as per contract.
Proper inward remittance documentation and AD Bank compliance must be maintained.
Customs Law
As goods are not physically exported outside India, Customs export provisions do not apply. Therefore:
No Shipping Bill or export customs clearance is required.
The supply does not qualify as "export of goods."
Export incentives such as RoDTEP, Duty Drawback, etc., are generally not available.
If machinery is imported before domestic supply, applicable import duties and customs compliances remain applicable.
GST Law
Under the IGST Act, export requires physical movement of goods outside India. Since machinery is delivered to an Indian customer, the transaction is treated as a domestic taxable supply, even if payment is received in foreign currency. Accordingly:
GST must be charged as applicable.
CGST+SGST or IGST will apply based on place of supply rules.
Foreign currency receipt does not make the transaction zero-rated/export.
"Bill-to / Ship-to" provisions under Section 10(1)(b) of the IGST Act may apply for determining place of supply.
Compliance Recommendation
Maintain:
Purchase Order / tripartite agreement,
GST invoice with proper Bill-to / Ship-to details,
Foreign remittance records (FIRC/BRC, if applicable),
Delivery proof and end-user documents,
AD Bank correspondence and contract records.
Hence, the transaction is legally feasible under FEMA and RBI regulations, but it will generally be treated as a domestic taxable supply under GST and not as an export under Customs/GST laws.
