Quality Assurance

Every shipment of Industrial Grade Sulfamic Acid undergoes multi-point analytical testing to ensure batch-to-batch consistency and prevent equipment corrosion or process variation in your facility.

Purity & Assay Verification: Tested via standard acid-base titration to guarantee active acid content consistently meets or exceeds 99.8%.

Trace Impurity Profiling: High-sensitivity ICP-OES/AAS analysis for Iron (Fe ≤0.003%) and Heavy Metals (as Pb ≤10 ppm) to prevent unwanted catalytic side reactions or metal staining in high-precision descaling formulations.

Sulfate & Moisture Control: Ion chromatography and loss-on-drying protocols ensure low sulfate content (≤0.05%) and free-flowing powder performance without clumping during automated bag-dumping operations.

Full Batch Traceability: Each pallet is labeled with a unique Lot/Batch Number linked directly to raw material origin logs, production line time, and retained lab samples (stored for 24 months).

Packaging, Storage & Shipping

Packaging
25 kg polyethylene-lined bags
500 kg jumbo bags
PP bags or kraft paper bags according to the agreed packaging specification
Customized bulk packaging available subject to order requirements
Storage
Store in a cool, dry, and well-ventilated area. Keep packaging sealed and protected from moisture and contamination. Storage conditions should also prevent contact with incompatible substances.
Shipping
Industrial Grade Sulfamic Acid can be arranged for road, sea, or rail transportation, depending on destination, order volume, and logistics requirements.

FAQ

Q: How should I choose between 25 kg bags and 500 kg jumbo bags?

A: We normally recommend selecting packaging according to your handling equipment and consumption rate. A 25 kg package is practical for manual or smaller-batch dosing, while 500 kg jumbo bags are more suitable for high-volume operations using mechanical lifting and feeding systems.

Q: What information should I provide when requesting a bulk quotation?

A: Please provide the required quantity, destination port or country, packaging preference, target specification, and expected purchasing frequency. These details allow us to evaluate the appropriate packaging and logistics arrangement rather than quoting solely on a nominal per-ton basis.

Q: Can you provide a sample before we place a bulk order?

A: Yes. We can discuss sample quantities for technical evaluation so your team can verify dissolution behavior, process compatibility, and product performance before moving to commercial-volume procurement.

Q: What certifications or compliance documents can you provide for Industrial Grade Sulfamic Acid?

A: We can provide applicable product and regulatory documents based on the destination market, including SDS, TDS, COA, and Certificate of Origin. Specific certifications or compliance documents should be confirmed according to the importing country's requirements.

Q: Can I arrange a third-party inspection before shipment?

A: Yes. Buyers may appoint an independent inspection company to inspect the goods before shipment. The inspection scope, sampling method, inspection date, and applicable standard should be agreed before production or loading.

Q: What after-sales support do you provide if we identify a quality issue after delivery?

A: We will review the reported issue against the agreed specification and shipment records. Buyers should provide the batch number, inspection results, photographs if applicable, and relevant documentation so the case can be assessed efficiently.
