Quality Defined. Inspection Documented. Supply Traceable.

Each supply programme is structured around written product specifications, batch records, inspection requirements and a complete shipment-document matrix.

TSR20 technical benchmark

MJS can structure supply through established rubber-producing regions, depending on the required grade, volume, pricing, logistics and buyer compliance requirements.

Technical values shown on the website are an indicative MJS TSR20 benchmark. The final binding specification must always appear in the written quotation or supply contract.

Inspection and verification

Where required by the transaction, MJS arranges inspection through SGS, Bureau Veritas or another recognised independent inspector. The inspection scope can include quantity, packing, container condition, seals, sampling and quality testing at the port of loading or processing facility.

Typical document pack

Commercial documents

Commercial invoice, packing list and agreed payment reference.

Transport documents

Clean on-board bill of lading, container list and seal list.

Certificate of origin, certificate of analysis and independent weight / quality certificate.

Compliance positioning

MJS applies transaction-specific know-your-customer, sanctions, anti-money-laundering, source-offunds, customs and trade-document checks where required by banks, insurers, freight providers or law. Buyer and end-use information may be requested before supply is confirmed.

For traceability and deforestation-related due diligence, MJS supports producer, processor, origin, batch and production-area information to the extent legally applicable and available for the agreed supply chain
