Sugar Grades: Compare Specifications, Origin and Packaging
For importers, distributors, food manufacturers and repackers: choose sugar against one complete purchasing specification. ICUMSA 45, Indian S30, a producer name and a bag size describe different aspects of an offer. Confirm the required product, methods, origin and packaging before deciding whether two quotations are comparable.
Understand ICUMSA 45 and Indian S30
ICUMSA 45 commonly describes refined white sugar sold against a maximum colour of 45 ICUMSA units. It does not define crystal size, packaging or every acceptance limit. ICUMSA publishes test methods; agree the method and complete purchasing specification.
Bureau of Indian Standards guidance describes Indian sugar grading by colour and crystal size. S30 is a grade designation, not a measured result of 30 ICUMSA units. Ask for the producer’s grade declaration, applicable current standard and lot analysis rather than treating the number in the name as a laboratory value.

| Description | What to confirm | What it does not establish |
|---|---|---|
| ICUMSA 45 | Contracted colour maximum and applicable measurement method | Complete composition, crystal distribution or origin. |
| Indian S30 | Producer grade declaration, grading reference and lot results | Automatic equivalence to ICUMSA 45 or a 30-IU result. |
| Producer or brand | Product identity, specification and authenticity evidence | A guaranteed grade or an authorised seller relationship. |
| 25 kg, 50 kg or bulk format | Actual pack design, net weight and handling requirements | The sugar’s analytical or application suitability. |

Compare sugar specifications and test methods
Use one acceptance sheet for all offers: specification revision, sample/lot identity, parameter, limit, method/year and unit. A COA reports results for identified material under its stated scope; it cannot replace missing requirements.
ICUMSA solution colour is a laboratory measurement, distinct from dry-crystal appearance. Have the producer and laboratory agree a method for the expected colour range; one method does not cover every sugar.

| Field | Buyer’s check |
|---|---|
| Colour | Maximum, ICUMSA units and full method reference. |
| Polarimetric sucrose content | Minimum, method and unit. ICUMSA GS2-1 reports this measurement in °Z. |
| Moisture | Maximum and method; include pack and storage requirements. |
| Conductivity ash and reducing sugars | Separate limits, methods and units when required. |
| Crystal-size distribution | Sieve results or another agreed size description for the process. |
| Other application/safety requirements | Relevant insoluble matter, sulphur dioxide or destination-specific checks, with agreed limits. |

Match crystal size, origin and packaging to the job
Select against the production brief. Crystal-size control can matter to dissolving and consistent manufacturing, as British Sugar’s screened-sugar guidance illustrates. Assess a representative sample under your own processing conditions.
Record producer, country of production, dispatch location and required origin evidence separately. A brand or loading port does not settle origin. Keep product identification consistent across the offer and shipment records.
Choose pack format around unloading, storage, repacking and label requirements. Confirm bag construction, liner where needed, closure, net-weight tolerance, pallet arrangement, lot coding and shipping marks. Producer packaging examples are not a promise that every format is available through Zenith for every enquiry.

Practical limits and common buying mistakes
A complete specification makes omissions visible. A lower colour result cannot settle a missing crystal-size requirement, unsuitable packaging or an unresolved document question.
- Do not translate “S30” into an assumed ICUMSA colour value.
- Do not compare measurements without their method, unit and sample identity.
- Do not treat a producer’s generic specification as the COA for the offered shipment.
- Do not assume “fine”, “refined” or a brand name defines identical products across sources.
- Do not accept a product substitution without technical and commercial review.
- Do not compare headline prices while pack, delivery point, inspection or document scope differ.
Hypothetical example: two sugar offers
A beverage manufacturer requires a defined colour maximum and crystal distribution. Offer A says “ICUMSA 45” but omits size results. Offer B says “S30” but omits the colour method and lot COA. The buyer asks both suppliers to complete the same acceptance sheet, then reviews a suitable sample in its process. Neither name alone resolves the missing information.
This is a buying exercise, not a Zenith order, a grade specification or an assumed approval.
Send a comparable sugar quotation request
For the agreed shipment, confirm the signed specification, sample or lot COA, invoice, packing/weight list, transport document and any required origin evidence. Health, sanitary, inspection or other records depend on the destination and contract; do not assume a universal certificate set.

Buyer questions
Is Indian S30 equivalent to ICUMSA 45?
The names use different conventions. Require measured colour, method, crystal-size information and the other agreed tests to decide whether an offer meets your specification.
Does a lower ICUMSA colour result mean the best sugar for every use?
No. Select against the application’s full requirements, including crystal size, composition, pack format and process trial where useful. Colour answers one part of that decision.
Can I accept a generic producer specification instead of a lot COA?
A producer specification describes requirements or product targets. A lot COA reports results for identified material. Agree which records and sampling evidence your purchase requires and resolve missing links before acceptance.
What should I send if I have not chosen a grade?
Describe the finished product, production or resale process, quantity, destination and packing needs. Mark uncertain technical requirements “Not sure” and share an existing specification or reference sample if available.
