Importing Glass Marbles from China: What Drives Landed Cost and How to Verify It
The four inputs that set your glass marble unit price, why packing moves freight more than the marble does, and the checks to agree before you release a balance payment.
Landed cost for imported glass marbles is set by four inputs: diameter band, colour or pattern complexity, packing format and order quantity. SunWard Products Co., Ltd. has manufactured glass marbles in Zibo, Shandong since 1999, and the pattern we see in quotations is consistent — buyers who fix those four inputs before comparing prices avoid the re-quote that costs a month. MOQ is 1 ton, payment is T/T, and popular sizes ship from stock.
The four inputs that decide your unit price
Diameter band, colour or pattern, packing format and volume, in that order of impact. A standard 16 mm solid colour in an export carton is the baseline; a tight tolerance band, a custom petal colour or a retail hangable card each adds cost. Volume then spreads the fixed setup across more units, which is why the 1 ton minimum exists.
Ask each supplier to quote the same four inputs in writing. A cheaper quote almost always differs on one of them — usually the packing format, which is where most of the visible price gap sits.
Packing moves your freight more than the marble does
Glass marbles are heavy, so the packing format decides the freight class, not just the unit cost. Export cartons at 20–25 kg per carton and woven bags at 10–25 kg are the bulk baseline; PVC bags at 250 g–2 kg and hangable cards at 50–500 pcs multiply the number of outer cartons for the same tonnage, which changes both carton count and palletisation. Fix weight per bag, carton dimensions and pallet configuration before booking freight.
If the marbles go straight to a retail peg, the packing has to match the shelf format — but confirm the extra carton count is priced in. Quietly switching a bulk order to retail packing at the last minute is the most common reason a shipment arrives over budget.
Quality checks to agree before production
Agree four checks in writing before the run starts: diameter band and how it is screened, colour or pattern against the approved sample, surface condition (no chips or sharp points on toy-grade stock), and packing weight tolerance per bag. SunWard's factory is BSCI audited and our marbles meet EN71, which covers the toy-channel baseline; confirm any additional market-specific standard separately.
Keep the approved sample. Colour and pattern are the two attributes most likely to drift between lots, and a retained sample settles a dispute faster than a specification document, because it is physical evidence of what both sides agreed.
What to verify before releasing the balance
Verify in this order: (1) the finished goods match the retained sample on size, colour and surface; (2) the packing matches the agreed format and weight per bag; (3) the carton count matches the order and the packing list; (4) photographs or a short video of the actual cartons before loading. For a first order, an independent inspection is worth the cost.
SunWard loads containers at our own yard, so loading photographs are straightforward to provide. Ask for them before the balance is released rather than after the container has left.
FAQ
What is the MOQ for importing glass marbles from China?
SunWard's minimum order is 1 ton, and popular sizes are held in stock so a first trial order can ship without waiting for a production slot. Minimum quantity per colour and per packing format is confirmed on the PI, since mixed-colour assortments change the effective minimum.
How is payment handled?
Payment is by T/T. The exact split and timing are stated on the PI for each order, because they depend on whether the order ships from stock or from a scheduled production run. Confirm the terms on the PI before production rather than at shipping.
Can I mix several colours or sizes in one order?
Yes. SunWard produces 9–35 mm on the same lines, so mixed sizes and colours can ship together, and mixed retail packs can be built to a ratio you specify. Agree the ratio and the packing format in writing before production, because the ratio changes both carton count and packing cost.
Do you provide inspection evidence before shipping?
Yes. We load containers at our own yard and can supply photographs or video of the packed cartons before loading. For a first order an independent third-party inspection is usually worth arranging; tell us before production so the inspection can be scheduled against the finished goods, not after loading.
