How We Supplied 25 Tons of Fertilizer-Grade Manganese Carbonate to New Zealand

Executive Summary

• Product: Manganese Carbonate (MnCO₃, Fertilizer Grade)

• Volume: 25 Metric Tons (1 x 20ft FCL)

• Destination: Lyttelton Port, New Zealand

• Key Challenges: Strict New Zealand MPI biosecurity clearance, zero-wood packaging requirements, precise chemical declaration (CAS 598-62-9), and non-dangerous goods sea freight verification.

• Outcome: 100% compliant documentation, zero delay in customs clearance, and long-term supply agreement established.

1. Client Requirement & Background

A leading New Zealand agricultural enterprise reached out via our official website seeking a reliable supplier for fertilizer-grade manganese carbonate. The material was intended for pasture soil trace element enrichment and agricultural blending to fix local manganese deficiency.

Due to New Zealand’s stringent environmental and biosecurity import regulations enforced by the Ministry for Primary Industries (MPI), the buyer required a manufacturing partner capable of delivering both high-purity chemical quality and flawless customs documentation.

2. Key Challenges & Custom Solutions

Challenge A: Strict Biosecurity & Zero-Wood Packaging

New Zealand has some of the world’s strictest biosecurity controls regarding imported containers and packaging materials.

• Our Solution: We packed the 25 tons of Manganese Carbonate directly into 25 brand-new, clean woven jumbo bags (1,000 kg each) without using any wooden pallets, crates, or wood bracing. We completed the official Sea Container Quarantine Declaration, confirming zero restricted packaging or soil contamination.

Challenge B: Biosecurity Non-Contamination Assurance

The buyer needed absolute proof that the product contained no biological, animal, or seed contaminants.

• Our Solution: We issued a formal Manufacturer’s Declaration & Process Certificate under Btlnewmaterial. It detailed our complete 10-step chemical synthesis—from liquid reaction, precision filtration, and heavy metal removal to high-temperature drying—guaranteeing 0% organic, seed, or animal matter contamination.

Challenge C: Precise Customs Classification (CAS 598-62-9)

Declaring inorganic chemicals incorrectly as “animal feed” or general “supplements” in New Zealand leads to lengthy quarantine delays.

• Our Solution: All shipping documents—including the Commercial Invoice, Packing List, and Certificate of Analysis (COA)—explicitly classified the cargo as “Manganese Carbonate (Fertilizer Grade), CAS No. 598-62-9”.

Challenge D: Sea Freight Safety Certification

To ensure smooth booking and port handling without dangerous goods surcharges, the ocean line required official safety verification.

• Our Solution: We provided an official Certification for Transport of Goods by Sea (Report No. 212607200022) issued by NBTS. The report certified the cargo as Non-Dangerous General Goods under IMO IMDG Code (Edition 42-24).
