If you already have a dehydrated onion supplier you trust and simply want an independent check before shipment, a third-party inspection firm such as SGS, Intertek or QIMA is often all you need. If you still have to find the plant, judge whether it is a real processor, set up testing to your market's limits and follow the order from sample to loading, a sourcing agent covers more of the job, and some buyers use both.
The two services overlap less than people think. Inspection answers "does this lot match the brief today?" Sourcing answers "is this the right supplier, and is the whole order under control?"
What the inspection firms do
SGS, Intertek and QIMA are large, well-known testing, inspection and certification companies, all with operations in India. For food buyers they typically offer factory audits, pre-shipment inspection, loading supervision, sampling for laboratory testing and the laboratory work itself. Their reports are widely recognised by importers, banks and authorities, and that recognition is a genuine strength.
They work to the brief you give them. An inspector will check what your checklist says: carton count, labels, weight, visible defects, moisture by a stated method, sampling for a stated test panel. If your brief is good, the result is reliable and independent. If the brief misses something, such as ethylene oxide testing or the right mesh size check for powder, the report will not catch it. Booking, scope and the availability of an inspector in a smaller town such as Mahuva are worth confirming in advance.
What a sourcing agent does
A sourcing agent starts earlier. It finds plants, checks whether a supplier is a processor or a trader, audits the site, helps you write the specification, arranges samples, gets each lot tested at an accredited laboratory against your market's limits, attends loading and checks the documents. It is involved across the order rather than on one day. A good agent can also arrange third-party inspection when a buyer, bank or customer requires a branded report; see an agent arranging third-party inspection.
Side by side
How the two compare on a dehydrated onion order:
- Supplier selection: inspection firms audit a factory you name. An agent also finds and shortlists factories.
- Scope: inspection is a defined job on a defined date. An agent's work runs from shortlist to shipped container.
- Brief: with inspection, you write the checklist. With an agent, you agree it together, drawing on what typically goes wrong with onion: salmonella, ethylene oxide, pesticide residues, moisture, caking and foreign matter.
- Recognition: inspection reports from large firms carry weight with banks and customers. An agent's report is only as credible as the agent and the accredited laboratory behind it.
- Cost drivers: inspection is priced per visit or per test. An agent usually charges an agreed fee for the order or the relationship.
- Follow-up: if a lot fails, an inspection firm reports the failure. An agent helps deal with it, from retesting to replacement lots. See what happens when goods fail inspection.
Which suits you
Inspection only suits importers with an established supplier, a well-written specification and staff who can manage the supplier themselves. It also suits buyers whose customer or letter of credit names a specific inspection body.
A sourcing agent suits buyers placing a first order in India, switching suppliers after a problem, or without someone who knows the dehydration industry. Our general article on agent inspection vs third-party inspection covers the same question across product types, and loading supervision explains what anyone at the loading should check.
Whichever route you use, make sure the laboratory is accredited and the report names the lot. Our page on whether NABL laboratory reports are accepted in the EU, US and UK explains what that means in practice.
Using both
Plenty of buyers combine the two: an agent to find, audit and manage the supplier, and an inspection firm to issue a pre-shipment certificate that a bank or a retail customer requires. That costs more, but each does what it is best at. For other comparisons, see IndiaMART or Alibaba vs a sourcing agent and sourcing agent vs freight forwarder.
