Buying shipping boxes wholesale in Thailand: 6 things to ask before a bulk order

A shipping box looks like a simple item, but ordering the wrong size or thickness a thousand at a time turns into cost you cannot use. Before a bulk order, ask these six things. 1. Size the box from the packed product — box size is given as width × length × height. Measure the product together with its cushioning first, then pick a box that fits. An oversized box raises shipping cost, because many couriers charge by volume (width × length × height divided by a number each courier sets) and bill that figure when it is larger than the actual weight. Ask the courier you use how it works it out. 2. Stock boxes come in numbers, but sizes are not identical everywhere — ready-made parcel boxes are usually sold by number such as 00, 0, A, AA, B, C, but each number varies slightly by maker (for example, some shops list no. 00 as 9.5 cm wide and others as 9.8 cm). Always ask the seller for the size in centimetres, and order a sample to try your product in first. 3. Number of layers and flute — in the box trade, "layers" (ชั้น) counts sheets of paper: a 3-layer box has one fluted layer, a 5-layer box has two stacked, so it is thicker and carries more. The "flute" (A, B, C, E) is the height of the corrugation: a small flute such as E has a smooth surface that prints well, a large one such as A cushions better. The thickness figures quoted by shops are approximate, not a fixed standard, so ask the factory: "how many layers, which flute, what grade of liner and fluting paper, and what weight will it carry for my product?" Then choose to match your product’s weight and how the boxes will be stacked in storage. 4. For printed or custom-size boxes, ask about minimums and tooling — many factories advertise low or no minimums, but that is advertising, so ask for the real number per size and per print design. Ask for a quotation that separates tooling (plate or die-cut charges, if any) from the price per box, and ask for tiered prices, for example 500 / 1,000 / 5,000 boxes. Ask whether changing the artwork or reordering later costs extra, and get a proof or sample approved before the full run. 5. Storage space and humidity — boxes arrive flat or already formed, and the space they need differs a lot, so ask which form, how many per bundle and bundles per carton. Paper is sensitive to moisture: keep boxes dry and off the floor, since damp boxes go soft and carry less. Work out the storage space before ordering extra to get a lower unit price. 6. Delivery, timing and damaged boxes — ask about production and delivery time, how freight is charged, and whether it is delivered or collected. On receipt, count the boxes against the quotation, check the size and print quality, and photograph any that are crushed, torn or misprinted. Agree beforehand how that is handled, and keep every chat and quotation. Browse sellers in the packaging category on Trust Gate and request a quote with the checklist above directly.
