White goods packaging for appliances — corner-protected, buffer-engineered corrugated systems that deliver scratch-free washing machines, fridges and coolers. This guide covers the governing IS 2771:2022 specifications, strength and moisture engineering, commercial terms (GST 5%, HSN 4819) and exactly how to specify the right box.
White goods packaging for appliances — corner-protected, buffer-engineered corrugated systems that deliver scratch-free washing machines, fridges and coolers.
Appliances fail cosmetically before they fail mechanically. Corner posts, buffers and snug outer sleeves keep finished surfaces untouched from plant to living room.
Indian corrugated boxes are governed by IS 2771 (Part 1): 2022. The bands relevant here:
| Board type | Max contents | Max L+W+H | Min bursting strength | Min ECT |
|---|---|---|---|---|
| Double wall (5-ply) | Up to 20 kg | 1525 mm | 12 kgf/cm² | 5.0 kN/m |
| Up to 25 kg | 1715 mm | 13 kgf/cm² | 5.3 kN/m | |
| Up to 30 kg | 1905 mm | 14 kgf/cm² | 5.6 kN/m | |
| Up to 40 kg | 2286 mm | 17 kgf/cm² | 7.0 kN/m | |
| Triple wall (7-ply) | Up to 55 kg | 2667 mm | 24 kgf/cm² | 9.6 kN/m |
| Up to 75 kg | 2921 mm | 35 kgf/cm² | 12.4 kN/m |
Reference values from IS 2771 (Part 1): 2022, Bureau of Indian Standards — the governing Indian specification for corrugated fibreboard boxes. We engineer to or beyond these minimums for your load.
Stacking strength is engineering, not guesswork. Box Compression Test (BCT) capacity can be estimated with the McKee formula — BCT ≈ 5.87 × ECT × √(board caliper × box perimeter) — and then verified on the actual box. We apply safety factors of 2× for short-cycle distribution up to 4× for long-hold warehousing (per ASTM D642 practice), because long-term usable strength under load creep is only 50–60% of the peak laboratory value.
Because this product serves a regulated, quality-sensitive buyer, every stage carries a checkpoint: incoming kraft is GSM-verified, board is Cobb- and burst-tested per lot, blanks are dimension-checked against the approved die line, and print is compared to your signed proof before dispatch. Test records travel with the consignment.
The right spec here balances protection with line efficiency and compliance: internal dimensions sized to your product with the correct clearance, board grade sized to stacking reality (not catalogue habit), and documentation matched to what your auditors or buyers actually ask for. We start from your product sample and transit route, then engineer backwards.
Commercially, corrugated boxes fall under HSN 4819, and GST on corrugated boxes was reduced from 12% to 5% with effect from 22 September 2025 — worth re-checking on old supplier quotations. Pricing is driven by board grammage (GSM), ply, kraft paper prices (which rose ~6% through 2025), printing and quantity; we quote engineered specifications within 4 business hours, offer sampling before you commit, and support everything from trial lots to annual rate contracts.
Every tonne of recycled-fibre corrugated board avoids roughly 180 kg of CO₂ versus virgin production (DEFRA life-cycle factors), and industry equivalences credit each tonne of recycled paper with saving about 17 trees, ~26,500 litres of water and ~4,000 kWh of energy (US EPA). Corrugated is also India’s practical answer to the single-use-plastic phase-out: recyclable, repulpable and biodegradable in weeks rather than centuries.
Product never touches raw flute edges — buffers, liners and clearance design keep finished surfaces isolated.
Yes — we reverse-engineer current packs and usually improve material efficiency in the process.
Corrugated boxes fall under HSN 4819; GST was reduced from 12% to 5% effective 22 September 2025 (56th GST Council). We invoice at the current applicable rate with full documentation.
MOQs depend on size and print complexity — trial lots are welcome, and repeat production is scheduled to committed dispatch dates. Sampling comes first on request; quotations are returned within 4 business hours.
Yes — scheduled routes cover the full 160 km radius around our Kosamba, Surat plant (Surat, Hazira, Navsari, Bharuch, Ankleshwar, Vapi, Valsad, Daman, Silvassa, Vadodara), with pan-India full-truck programmes beyond it.
