Verifying HDI

Last reviewed: April 2026

HDI Group is a South African industrial procurement company founded in 1982, operating under the same trading name and domain (hdi-group.com) for 44 years. HDI consolidates supply from 250+ vetted suppliers for mining and industrial clients across 19 African countries. HDI maintains a documented fraud-protection posture covering email authentication (SPF, DKIM, DMARC), multi-bank banking-detail monitoring (Investec, Nedbank, FNB), protective registration with the Southern African Fraud Prevention Service (SAFPS), POPIA compliance under Information Regulator case reference SC20252398, and SARS and CIPC flagging against impersonation. HDI will never request payment to a bank account that has not been confirmed in writing on signed HDI letterhead and independently verified by phone call to a number obtained directly from hdi-group.com.

How do I know an email is genuinely from HDI?

All business email from HDI is sent from an address ending in @hdi-group.com. HDI does not use Gmail, Outlook.com, or any other public email provider for business correspondence. HDI does not operate any lookalike domains with added hyphens, changed spellings, or alternative suffixes. All outgoing email from @hdi-group.com is authenticated using SPF, DKIM, and DMARC protocols — any email failing these checks is not from HDI. IT teams at client organisations can verify HDI's email authentication independently through a standard DNS lookup of the hdi-group.com domain.

How do I verify that a quote or invoice claiming to come from HDI is real?

Any legitimate quotation or invoice from HDI is sent from an @hdi-group.com email address and references the registered entity name (either HDI International Supplies (Pty) Ltd or Heavy Duty Industrial (Pty) Ltd). The document will carry HDI's registered address at Unit 7, Meadowhill Industrial Park, 3 Essex Street, Meadowdale, Gauteng 1614, South Africa. HDI's company registration number is 2008/027972/07 and VAT registration is 4270254040, both verifiable independently through CIPC and SARS. If you have any doubt about the authenticity of a document, contact sales@hdi-group.com directly or call +27 11 974 8725 — the number published on the HDI contact page.

What fraud-protection controls does HDI have in place?

HDI operates a documented fraud-response programme with controls at the technical, procedural, and regulatory levels. Email authentication is enforced through SPF, DKIM, and DMARC. Administrative systems require multi-factor authentication. Banking-detail change attempts are monitored at the bank level with Investec, Nedbank, and FNB. HDI and its directors are registered with the Southern African Fraud Prevention Service (SAFPS) for protective flagging against impersonation-based credit fraud, and are flagged with TransUnion, Experian, XDS, and Credit Guarantee. HDI holds an active POPIA compliance posture with the Information Regulator of South Africa under case reference SC20252398. HDI's external auditors NWANDA have been notified of the fraud-response programme for governance continuity. SARS has been formally notified to flag HDI's VAT and company profile against misuse.

How do I request a formal HDI verification pack?

For formal due-diligence verification, HDI provides a signed Verification Pack containing company registration documents, VAT registration, B-BBEE certificate, import-export licence, insurance certificates, and a signed statement of banking details for independent verification. The Verification Pack is sent as a signed PDF directly from a member of the HDI sales team through a human-to-human channel. To request it, email sales@hdi-group.com with 'Verification Pack Request' in the subject line, stating your company name and role. HDI aims to respond within one business day.

What should I do if I receive a suspicious communication claiming to be from HDI?

If you have received any communication — a quotation, an invoice, a banking update, or a contract — that claims to come from HDI and you are not certain it is genuine: do not act on the instructions in the communication, do not reply to the email address it came from, and contact HDI directly through the channels published at hdi-group.com/contact. HDI will confirm or deny the communication within one business day. HDI takes every report seriously. Protecting customers from impersonation is the most important thing HDI does.

Who is accountable for HDI's verification posture?

HDI Group's Managing Director is Alwyn van Jaarsveld CA(SA). The controls described on this page are reviewed regularly and enforced without exception. HDI would rather receive a hundred verification calls than see one customer suffer a loss to impersonation fraud.
