Darbhanga is one of north Bihar's medicine trading towns, and Darbhanga Medical College and Hospital (DMCH) stands in Laheriasarai. This page is for pharma wholesalers, distributors and stockists in Darbhanga. It covers the local market, the GST and drug licence offices for the district, and how ValueSoft handles batch-wise billing, expiry and chemist dues.
Where is Darbhanga's medicine trade?
Live Hindustan has called Hospital Road the biggest medicine market (dawa mandi) in north Bihar (January 2020). In 2025 the same paper ran a report on the medicine traders of Benta in Laheriasarai, and Prabhat Khabar has reported on a wholesale medicine trader near Darbhanga Tower (June 2025), so the wholesale trade is not in one lane only. Darbhanga's medicine shops were among those that shut in the chemists' strike of 20 May 2026 (Amar Ujala).
For a Darbhanga wholesaler the daily work is the same as in any busy market: a crowded counter, batches that must be sold before they expire, chemists who buy on credit, and supplier bills arriving every day. Software helps most where these overlap, for example by warning you about a near-expiry batch while the bill is still open.
Which GST and drug licence offices serve Darbhanga?
A medicine wholesaler deals with the State tax department and the Central tax (CGST) commissionerate for GST, and with the State drug control office for the wholesale drug licence. In brief, as of 23 October 2026:
GST
State tax. Darbhanga falls in the Darbhanga division of Bihar's Commercial Taxes Department. The division has the Darbhanga circles and also the Begusarai, Jhanjharpur, Madhubani, Samastipur and Teghra circles.
Central tax. Darbhanga district comes under the CGST Patna-II Commissionerate, which covers 21 districts, including Muzaffarpur, Darbhanga, Purnia and Kishanganj.
Wholesale drug licence
Drug sale licences in Bihar, including wholesale licences on Forms 20B and 21B, are handled by the Drugs Control Administration, headed by the State Drugs Controller at Swasthya Bhawan, Sheikhpura, Patna. Since 1 April 2025, new licences and renewals are applied for online through ONDLS (statedrugs.gov.in). Darbhanga has its own Assistant Drugs Controller (Prabhat Khabar, October 2024).
What does a Darbhanga wholesale bill need?
Rule 65(5) of the Drugs Rules, 1945 says every wholesale supply must be made against a cash or credit memo that carries your name, address and licence number, and shows:
- the date of sale;
- the buyer's name, address and sale licence number (for a hospital, a doctor or a government buyer, their name and address);
- the name of the drug, the quantity and the batch number;
- the name of the manufacturer, and the signature of the competent person under whose supervision the sale was made.
Copies are kept for three years. The same bill is your GST tax invoice, so it also needs the buyer's GSTIN (if registered), the HSN code and the right tax. ValueSoft prints your drug licence number and the buyer's on every bill, and bills each item batch-wise with its expiry and MRP. Not sure how PTR and PTS (price to stockist) are worked out from MRP? Try our PTR / PTS calculator.
GST rules for medicine wholesalers in Bihar
- State code 10. Every GSTIN registered in Bihar starts with 10. A sale to a buyer inside Bihar carries CGST and SGST; a sale to a buyer in another state carries IGST. If you sell to a buyer outside Bihar, that bill carries IGST.
- Rate. Since 22 September 2025, drugs and medicines are taxed at 5% GST, apart from those notified at nil rate.
- E-Way Bill. Rule 138 of the CGST Rules asks for an E-Way Bill before goods worth more than ₹50,000 move. For movement inside Bihar, the State's own notification sets the limit, so check the current figure with your CA.
- e-Invoice. Needed for B2B invoices, credit notes and debit notes once your aggregate turnover crossed ₹5 crore in any financial year from 2017-18 (from 1 August 2023). At ₹10 crore or more, each one must be reported to the IRP within 30 days (from 1 April 2025).
ValueSoft picks CGST and SGST or IGST from the buyer's state, so the bill and your GSTR-1 match. Use the GST calculator for a quick check on any amount.
