Price Ranges You Should Expect
Natural 园林鹅卵石 in common gradings typically sit at the lower end of the decorative stone price range, white 和 黑色鹅卵石 cost more because color sorting is manual, 和 抛光鹅卵石 carry the highest premium because each stone is ground 和 polished individually.
Within one 产品 class, size grading changes price too: very small or very large gradings yield less from raw stone 和 are screened more carefully, so they cost more per tonne than the popular mid-range sizes such as 2–3 cm or 3–5 cm.
Factor 1: 颜色 Sorting Is Handwork
The single biggest cost driver in pebble production is color consistency. A natural mixed pebble can be machine-graded; a uniform white pebble is sorted by hand, piece by piece. That labor is why 白色鹅卵石 cost noticeably more than natural tones 和 why very cheap 'white' quotes usually arrive mixed with cream or grey stones.
When comparing quotations, check whether the price assumes strict color sorting or a tolerance mix — the difference can be 20–30% on the same 产品 name.
Factor 2: Polishing Multiplies Processing Steps
Polished pebbles go through tumbling, grinding 和 a final polish — several extra production steps 和 days of machine time. The premium over 天然鹅卵石 is real processing cost, 不会 margin padding, 和 it is stable across suppliers because everyone pays for the same machine hours.
Polished stone also needs individual wrapping for export, which adds packing weight 和 reduces container loading slightly — both show up in landed cost.
Factor 3: Packing Choice Changes Cost per Tonne
Standard 20 kg woven bags are the cheapest packing per tonne. Jumbo bags lower bagging labor but need handling equipment at destination. Palletized bags add pallet 和 freight cost but slash unloading time for retail distribution.
Because ocean freight is charged per container rather than per tonne, packing that wastes container volume raises the freight component of every tonne you buy. Ask each supplier for bags per container 和 gross weight, 不会 just a 产品 price.
Factor 4: Freight Is Where Quotes Quietly Diverge
FOB price per tonne is only comparable when container utilization is identical. A supplier loading 24 tonnes per 20 GP 和 another loading 26 tonnes differ by roughly 8% in freight per tonne at the same ocean rate — before any 产品 discount.
For a realistic landed cost, take FOB price, divide by tonnes per container, add ocean freight per container plus destination charges, 和 divide by the same tonnage. Do this once 和 you can read any stone quotation in minutes.
How to Compare Two Quotations Fairly
Normalize everything to the same assumptions: identical grading, identical color tolerance, identical packing, identical Incoterms 和 destination port. Then compare landed cost per tonne, 不会 FOB price.
Finally weigh the soft factors: response speed, sample accuracy, 和 whether the supplier offered a loading plan without being asked. In stone trading, the supplier who documents details before the order is the one whose containers arrive as described.
常见问题
Why are 白色鹅卵石 more expensive than 天然鹅卵石?
Uniform color requires hand sorting stone by stone, which adds significant labor cost. Natural 混合鹅卵石 are graded by machine. A strict white color tolerance can add 20–30% over mixed natural tones of the same size.
What is the cheapest way to buy 景观鹅卵石 in bulk?
Buy natural or garden-grade pebbles in standard mid-range sizes (2–3 cm or 3–5 cm), packed in 20 kg woven bags without pallets, 和 consolidate several materials in one container to maximize utilization. Gravel delivered instead of pebbles also cuts cost for large areas.
How much does polishing add to pebble stone price?
Polishing adds several processing steps (tumbling, grinding, polishing) plus individual wrapping for export, so 抛光鹅卵石 typically cost substantially more than natural-finish pebbles of the same grading. Reserve polished stone for close-up design features rather than broad coverage.
Should I compare suppliers on FOB price or landed cost?
Always landed cost. Two FOB quotes can differ by 40% 和 still land within a few percent of each other once container utilization, ocean freight 和 destination charges are included. Compare cost per tonne delivered to your port.
