Procurement FAQ
Frequently asked questions on a4 copy paper range
How many reams and cartons of A4 copy paper fit in a 20ft container?
+
A standard 20ft general purpose container (20GP) holds 8,000 reams (1,600 master cartons of 5 reams each) when floor-stowed without pallets, or 7,800 reams (1,560 master cartons) when loaded on 20 ISPM-15 fumigated export pallets.
What is the difference between 70 GSM, 75 GSM, and 80 GSM A4 copy paper?
+
80 GSM (2.50 kg/ream, 106–110 μm caliper, ≥95% opacity) is the international benchmark for two-sided duplex corporate printing. 75 GSM (2.34 kg/ream, ColorLok treated) reduces ocean container weight by 6.25% while maintaining jam-free office performance. 70 GSM (2.19 kg/ream) maximizes sheet yield per metric ton for high-volume draft copying.
Can we combine multiple brands or mix A4 and A3 sizes in a single 20GP container?
+
Yes. Importers can mix multiple basis weights (e.g., 50% 75 GSM + 50% 80 GSM) or combine A4 and A3 cartons (e.g., 800 cartons A4 + 400 cartons A3) within a single 20GP trial container.
What quality certifications and customs documents accompany each shipment?
+
Every container shipment includes a batch-tested Mill Certificate of Analysis (COA per ISO 2470 / ISO 2471), Commercial Invoice, Packing List, Ocean Bill of Lading, Certificate of Origin (CO / Form E / FTA), Phytosanitary Certificate, and optional SGS pre-shipment inspection report.
