Quick answer:
Two wholesale quotes for the "same" 1.2 m aquarium can differ by more than 100%, and usually neither is wrong — one is quoting the glass tank only, the other includes cabinet, pump, and lighting. Before comparing prices, align the scope on eight lines: glass spec, sump, cabinet, pump, lighting, heating or chilling, media and plumbing, and delivery term. A complete set typically runs 2–3× a tank-only price, and that gap is legitimate — the danger is discovering it after you have ordered.
Why Two Quotes for the "Same" Tank Differ by 100%
The word "tank" means different things to different suppliers. A factory quoting a glass aquarium often stops at the glass box and overflow. Another treats "tank" as the complete ready-to-fill system. Both can be honest, and both will quote numbers that cannot be compared until the scope lines are written out.
The practical rule for wholesalers: assume nothing is included. Every component that is not written into the quote is a later add-on priced at a worse rate than it would have been in the original package.
The Three Scope Tiers
Most wholesale quotes fall into three tiers, and the price difference between them is structural, not arbitrary.
| Scope tier | What is included | Typical share of complete-set price |
|---|---|---|
| Tank only | Glass tank, overflow, sometimes sump | 35–50% |
| Tank + cabinet | Above, plus stand or cabinet | 60–75% |
| Complete set | Above, plus pump, LED, heater or chiller, media, plumbing | 100% |
A wholesaler comparing a tank-only quote from one factory against a complete-set quote from another is comparing a component with a finished product. The 2–3× gap is real money, not margin.
What a Comparable Wholesale Quote Must List
To make quotes comparable, the RFQ should force every supplier to answer the same eight scope lines. A quote that leaves any of these open is not comparable yet.
| Scope line | What to specify | Why it changes the price |
|---|---|---|
| Glass | Type (low-iron/float), thickness (mm), bracing | 30–50% of a tank-only price |
| Sump | Volume (L), included or extra | Sump alone is often 10–15% |
| Cabinet | Material (stainless/MDF/wood), finish | 20–30% when included |
| Return pump | Flow (L/h), brand, included | $40–150 depending on quality |
| Lighting | Wattage, spectrum, included | $60–300 on a 1.2 m tank |
| Heating / chilling | Heater (W) or chiller, included | Chiller can double a quote |
| Media and plumbing | Media type, pipe kit, included | Small line, constant source of re-quotes |
| Delivery term | EXW/FOB/CIF/DDP | 5–25% swings in landed price |
Incoterms matter as much as components: a DDP quote looks higher than an EXW quote and may still be cheaper once freight and customs are added. Always state the delivery term in the same line as the price.
A Worked Example
A distributor asked three factories for a price on a 1.2 m reef-ready aquarium, 20 units, delivered FOB (hypothetical, for budgeting). The replies came back at $280, $430, and $580 per unit — a 107% spread.
When the distributor asked each supplier to fill the eight scope lines, the picture changed. The $280 quote was tank only, no sump, no pump. The $430 quote added cabinet and return pump but excluded lighting. The $580 quote was a complete set with LED, heater, media, and plumbing. After aligning all three to the complete-set scope, the real price gap closed to $40 per unit. The apparent $300 difference was almost entirely missing components, not factory competitiveness.
How to Align Quotes Before Comparing
Three habits keep wholesale comparisons honest:
- Send a scope list, not a size. State "1.2 m complete set: low-iron glass, sump, stainless cabinet, return pump, LED, heater, media, plumbing, FOB." Every supplier prices the same box.
- Ask for a line-item breakdown, not a total. A single lump sum hides the very lines that will be re-quoted later.
- Anchor the spare parts and warranty in the same document. A set that needs factory-only spares costs differently over five years than one with local parts.
Ruibit quotes wholesale orders on the eight scope lines above, with a line-item breakdown and the spare parts list attached, so the number on the page is the number you can compare across factories.
Send your tank size, quantity, and target market, and we will return a complete-set quote on the eight lines — no hidden scope, no re-quote three weeks later.

FAQs
Why do wholesale quotes for the same tank differ so much?
Scope. One factory quotes glass only, another includes cabinet, pump, and lighting. A complete set typically costs 2–3× a tank-only price — and that gap is legitimate.
What scope lines should a comparable quote list?
Glass spec, sump, cabinet, return pump, lighting, heating or chilling, media and plumbing, and the delivery term. Any quote missing one of these is not comparable yet.
How do I compare tank-only and complete-set quotes?
Align them to the same scope first. Ask every supplier to price the same component list and give a line-item breakdown, not a lump sum. Then compare.
Does Incoterms affect the price?
Yes, 5–25%. A DDP quote looks higher than EXW but may be cheaper after freight and customs. State the delivery term on the same line as the price.
What should I anchor besides the price?
Spare parts and warranty. A set needing factory-only spares costs differently over five years than one with local parts. Get both in writing with the quote.
