GST, HSN Codes and Bulk Billing: A Hotel Buyer's Guide to Mattress Procurement

Mattress procurement for a hotel, hostel or institution isn't just a price negotiation — the paperwork has to hold up in accounting, and for government or institutional tenders, it has to satisfy documentation requirements that a consumer purchase never needs to. Here's what actually matters on the invoice.

HSN code and GST rate

Mattresses in India fall under HSN code 9404, and are taxed at 18% GST. This applies uniformly whether the mattress is Pocket Spring, Bonnell Spring, foam, or a hybrid construction — the HSN classification is based on the product category (mattresses and bedding articles), not the internal spring mechanism.

If a quote you receive doesn't list an HSN code, or lists a different GST rate without explanation, ask before ordering — it's a sign the seller isn't set up for proper B2B invoicing, which becomes your problem at audit time, not theirs.

What a compliant bulk invoice needs

For standard hotel or hospitality procurement:

• Seller's GSTIN
• HSN code (9404) against each line item
• GST rate and amount broken out separately from the base price (not bundled into a single figure)
• Quantity, unit price and any bulk discount shown as a line item, not folded into the unit price silently

Additional requirements for institutional and government tenders

Schools, hospitals, government hostels and similar institutional buyers often need more than a standard GST invoice:

• Manufacturing certification — ISO 9001 or equivalent, often required as a submitted document alongside the tender, not just mentioned in marketing material
• Batch/quality test records — some tenders require evidence of compression-cycle testing or material specifications (coil gauge, foam density) as part of the technical bid
• Delivery and installation timelines in writing — tenders are frequently evaluated partly on committed delivery schedule, not price alone

A common mistake in bulk orders

Buyers sometimes negotiate a bulk discount verbally and then find the final invoice doesn't reflect it as a transparent line item — it's absorbed into a slightly-lower unit price instead. This makes it harder to audit later and harder to renegotiate on the next order, since there's no documented discount rate to reference. Ask for the discount shown explicitly.

Before you sign the purchase order

• Confirm HSN 9404 and 18% GST are both on the formal quote, not just the verbal conversation
• Confirm warranty terms in writing, with the manufacturer's name (not just the brand name) — this matters if a claim needs to be filed years later
• For tenders specifically, confirm which certifications the manufacturer can supply as documents before the submission deadline, not after

Getting this right on the first purchase order saves procurement teams real time on every reorder after — once GSTIN, HSN and standard terms are on file, subsequent bulk orders move much faster through accounting.
