The short answer

Pharmaceutical exposure sits in the classification boundary between medicament, nutraceutical and cosmetic; physician samples and free supplies where credit is blocked by Section 17(5)(h); expiry returns and destruction with their credit note and reversal consequences; contract manufacturing and the job work versus supply characterisation; and cross border arrangements including clinical trial and regulatory support services, where the export and intermediary questions arise.

The classification boundary

A product licensed as a drug, labelled with a dosage and an indication, and used for the treatment or prevention of an ailment, is a medicament. A nutritional supplement sold as a food product is not, whatever its composition.

The evidence is the licence, the label, the dosage instructions and the marketing material, and the Supreme Court's line in Wockhardt Life Sciences and Puma Ayurvedic Herbal supplies the test.

Medical devices, diagnostic kits, reagents, implants and disposables sit in different headings with different rates, and a single procedure can involve items at three rates.

Where a product is genuinely borderline and the volumes are material, an advance ruling before launch is cheaper than a demand three years later.

The transaction level heads

Physician samples and free supplies: credit blocked under Section 17(5)(h), with a sample register reconciled to a monthly reversal.

Expiry returns: the credit note mechanism with the recipient's reversal linkage, within the November window, and a reversal on destruction supported by the regulatory certificate.

Trade schemes, bonus quantities and secondary discounts: Circular 92/11/2019-GST governs, and buy one get one free is a supply of two goods for one price rather than a free supply.

Contract manufacturing: job work where the goods belong to the principal, a supply of goods where the manufacturer buys the inputs and sells the output. The ownership and challan record decides it.

Clinical trials, regulatory dossiers and pharmacovigilance services for foreign principals: export of services if the five conditions are satisfied, with performance based and intermediary characterisation as the risks.

The controls

A stock keeping unit master mapping product, licence category, heading and rate with effective dates.

A sample and free supply register reconciled to a credit reversal every month.

An expiry file per batch: the return, the credit note, the destruction certificate and the reversal working.

For exports of services, an agreement, invoice and remittance file indexed together, with a note addressing the intermediary risk.

What to do on Monday

  1. Map every stock keeping unit to its licence category, heading and rate with effective dates.

  2. Reconcile samples and free supplies to a monthly credit reversal.

  3. Keep an expiry file per batch with the destruction certificate and the credit note.

  4. Index export agreements, invoices and remittances, with an intermediary risk note.

Questions we are asked on this

Is a nutraceutical a medicament?

Usually not, unless licensed, labelled and sold as a drug with dosage and indications.

Is credit available on physician samples?

No. Section 17(5)(h) blocks it, and the reversal must be tracked monthly.

How are expiry returns treated?

Credit note with the recipient's reversal, and a reversal on destruction with the regulatory record.

Is contract manufacturing job work?

Where the goods belong to the principal, yes. Where the manufacturer buys and sells, it is a supply of goods.

Are clinical trial services an export?

If the five conditions are satisfied. Watch the performance based and intermediary rules under Section 13.
