Regular Slotted Corrugated Boxes (RSC)
The most versatile corrugated box style for export shipping - manufactured factory-direct from Rajkot, India
Regular Slotted Corrugated Boxes (RSC) from Whizzpack
The Regular Slotted Container (RSC) is the world's most widely used corrugated box style, and for good reason. With four flaps meeting at the center to form the top and bottom, RSC boxes deliver consistent performance, flat-pack efficiently for ocean freight, and are accepted by virtually every carrier worldwide.
At Whizzpack, we manufacture RSC boxes in all standard flute types - A, B, C, E, and BC double wall - using virgin kraft fibre and recycled content blends. Every batch ships with full specification sheets and GSM reports, giving importers in the USA and UK the documentation they need for customs and quality control.

Key Advantages for US and UK Importers
Flat-Pack Freight Savings
RSC boxes ship flat, reducing ocean freight volume by up to 80% compared to pre-assembled boxes - a critical cost advantage for USA and UK importers on 20ft and 40ft container orders.
Eco-Friendly Materials
We use FSC-traceable virgin kraft and recycled kraft liners. Our fluting medium is sourced from certified mills. Biodegradable, recyclable, and OEKO-TEX safe - RSC boxes from Whizzpack meet UK and EU packaging waste regulations.
Consistent Kraft GSM
Each production run is tested for bursting strength and ECT before shipment. GSM reports, test certificates, and photos ship with every order - giving importers the paperwork needed for carrier compliance.
Custom Die-Cut Sizes
Our in-house die-cutting allows non-standard inner dimensions to within 1mm tolerance. Ideal for buyers sourcing boxes for specific product SKUs, subscription boxes, or custom insert trays.
Common Use Cases
Our rsc boxes are used across a wide range of industries by importers in the USA, UK, Europe, and beyond.
Frequently Asked Questions
What is the difference between B flute and C flute RSC boxes?
B flute (3.5mm thick) is stiffer and better for stacking, making it ideal for canned goods and retail shelf display. C flute (4mm) offers better cushioning and is the most common choice for general export shipping. Both are available in RSC style from Whizzpack.
What is the minimum order quantity for RSC corrugated boxes?
Our standard MOQ is 5,000 units per size. For mixed-size orders sharing the same flute type and kraft specification, we can discuss combining quantities across SKUs.
Can you manufacture RSC boxes to exact inner dimensions I specify?
Yes. We manufacture to your exact inner dimensions (L x W x H). Our design team will calculate the correct blank size and test carton compression before finalising production.
Do your RSC boxes meet ISTA or ASTM packaging standards?
Our boxes are produced to ECT and bursting strength standards consistent with ISTA 2A and ASTM D4169 requirements. Specific test reports can be arranged for orders requiring formal certification.
What documentation do you provide with each shipment?
Every order includes a packing list, commercial invoice, GSM test report, and production photos. Certificate of Origin, phytosanitary certificate, and GST invoices are provided for all export consignments.
How long does it take to ship RSC boxes from India to the USA or UK?
Production takes 18-25 working days from approved sample. Ocean freight from Mundra or JNPT to US East Coast ports averages 20-28 days. Total lead time for first orders is typically 7-9 weeks.
