What is the S1018 purpose code?
Purpose code S1018 is used when an Indian business sends money abroad to pay for mining services such as on-site processing, sampling or analysis of ores. This covers work like on-site beneficiation support, ore grade analysis, metallurgical testing, and other mining-related technical services performed by an overseas provider. It applies to the mining service itself, not to imports of mining equipment or machinery, which are treated as import of goods. Under RBI FEMA guidelines, this outward payment is classified under other business services and reported accordingly.
When to use S1018 purpose code?
Use S1018 when you are paying an overseas vendor for mining services connected to your operations, such as on-site ore processing support, sampling, testing or analysis work delivered to your business in India or at your mining site abroad. It is the correct RBI purpose code for professional and technical mining services bought from a foreign partner, whatever your business structure. S1018 covers the mining service, not the import of physical mining equipment or machinery.
When to use a different code:
- Use a code under import of goods when the payment is for mining machinery, tools or other physical equipment
- Use a code for technical consultancy services when the payment is for general engineering or management consulting not specific to mining operations
- Use the matching P code when you are receiving money rather than paying
Who typically uses S1018 purpose code?
Indian mining and mineral processing companies that hire foreign specialists for on-site processing, sampling and ore analysis services. It also applies to Indian EPC contractors, metal producers and engineering firms that pay overseas mining laboratories, assay providers or technical consultants for mine-site or ore-related services.
Examples of transactions covered
- Payment to a foreign mining services company for on-site ore processing support at an overseas mine
- Fees to an overseas laboratory for detailed chemical analysis and assay reports on ore samples sent from India
- Charges paid to an international metallurgical testing firm for pilot-scale beneficiation tests on your ore
- Retainer paid to a foreign mining technical consultant for periodic on-site inspections and analysis of ore quality
When NOT to use S1018 purpose code
- The payment is for imported mining machinery, tools or physical equipment (use an import of goods purpose code instead)
- The payment is for general engineering, management or technical consultancy not specific to mining services (use a suitable consultancy services code instead)
- The payment is for software or IT systems used in mining operations, such as geological modelling or mine-planning software (use an appropriate software or IT services code instead)
- You are receiving money rather than paying (use the matching P code)
Documents required
To send a payment under S1018, keep the following documents ready so your authorised dealer bank can verify the transaction and report it correctly under FEMA.
| Document | Purpose |
|---|---|
| Vendor invoice | Commercial invoice from the overseas mining services provider describing the on-site processing, sampling or ore analysis services and the amount payable. |
| Contract or statement of work | Service agreement, work order or SOW outlining the scope of mining services, locations, timelines and commercial terms. |
| Form A2 declaration with PAN | Standard RBI form where you declare the purpose as S1018 and provide your PAN and other remittance details. |
| Form 145 under Rule 220 | Income tax declaration for the outward remittance, with Form 146 from your CA if the taxable amount exceeds ₹5 lakh in the Tax Year and no Assessing Officer certificate is available. |
How is a S1018 Purpose Code declared?
Declaring the code is pretty straightforward. Here's how the payment gets tagged and reported.
- Receive the vendor invoice: Your overseas mining services partner bills you, clearly describing the on-site processing, sampling or ore analysis work delivered.
- Determine taxability: Establish whether the payment is chargeable to tax in India, since that decides which part of Form 145 you file.
- File Form 145: Submit the declaration before remitting, with Form 146 from your CA where the taxable amount exceeds ₹5 lakh in the Tax Year.
- Complete Form A2: State the purpose of the outward remittance as S1018 and submit the supporting documents to your bank.
- Get your MT103: Once the payment is sent, request the SWIFT MT103 as proof and retain your Form A2 record.
- With a traditional bank you handle each step of the payment journey. But with a platform built for cross-border payments, you can preselect a default purpose code so the payments go out smooth.

Common mistakes to avoid
A few common slips can hold up your payment or cause compliance issues. Here's what to watch for.
- Confusing service with equipment: Tagging a payment for imported mining machinery or tools under S1018 when it belongs under an import of goods code.
- Code and invoice mismatch: The code not matching what your vendor invoice describes, which flags the payment.
- Assuming a Rule 220(3) exemption: Skipping Form 145 on a payment that is not on the specified list, which carries a ₹1,00,000 penalty per instance.
- Incomplete documents: Missing invoice, contract or Form A2, so the bank holds the remittance until provided.
- Missing PAN or KYC: Incomplete verification stops the bank from releasing the payment.
- Using an outward code for an inward receipt: Applying a payment code to money coming in instead of the matching P code.
