Pre-shipment inspection, or PSI, is the last independent look at equipment before it leaves the factory or yard. For a foreign buyer in Indonesia, it answers a plain question: is what is about to be loaded actually the thing that was ordered, in the condition it was promised, with the paperwork to prove it?
The term causes confusion because “PSI” is used for two different things. This guide separates them, then walks through what a commercial PSI for industrial equipment really verifies, when to schedule it, and how to avoid the mistakes that turn a simple check into a costly surprise at the destination.
- Two meanings of PSI
- What a commercial PSI actually verifies
- PSI versus FAT and final inspection
- Timing: inspect before the crate is closed
- Packing and preservation in tropical sea freight

Two Meanings of PSI
The first meaning is governmental. Some countries have used private companies to check imports abroad for price, quantity and quality, mainly to protect national finances against problems such as customs duty evasion and commercial fraud. The World Trade Organization’s work on preshipment inspection exists because such programs affect exporters, and its agreement provides a review procedure for disputes between an exporter and an inspection agency.
The second meaning is commercial. A buyer, or a project owner, appoints an inspection company to check a shipment against the purchase order before it is released. This is a contractual quality control step, not a customs measure, and it is the type most industrial buyers in Indonesia mean when they ask for PSI.
The two can coexist on one shipment, and a commercial PSI does not satisfy any government requirement. Which official rules apply to your goods and route is a question for your customs broker or freight forwarder, not for the inspector.
What a Commercial PSI Actually Verifies
A commercial PSI verifies that the shipment matches the order and is ready to travel. It is not a test of design, and it does not prove performance unless it includes witnessing of a test. A typical scope includes:
- Identity and quantity: items, tag numbers, serial numbers and counts against the purchase order and packing list.
- Visual condition: damage, corrosion, missing parts, coating condition and general workmanship.
- Dimensions and configuration: key dimensions, connections and orientation where the order specifies them.
- Nameplates and markings: data on nameplates, labels and warning plates against the specification.
- Documentation: completeness of certificates, test records and manuals included with the shipment.
- Accessories and spares: loose items, commissioning spares and special tools that belong with the equipment.
- Packing, preservation and marking: suitability for the route, plus shipping marks that match the paperwork.
The scope should be written into the appointment. An inspector can only confirm what they were asked to confirm, and gaps are best discovered before the visit rather than after the equipment has arrived.
PSI Versus FAT and Final Inspection
A factory acceptance test, or FAT, proves that equipment performs as specified while it is still at the supplier. Final inspection is the supplier’s and buyer’s examination of the finished product against the order. PSI comes after both and focuses on the condition and identity of what is actually shipping.
Think of the sequence as a chain of confidence. Final inspection says the unit is built correctly, the FAT says it works, and PSI says that the unit that passed is the unit in the crate and that it will arrive intact. A weak link at any stage is hard to repair at the destination.
In practice PSI often reviews the FAT and final inspection records instead of repeating them. That is sensible, as long as the scope states which results are being accepted on the basis of records and which are being rechecked.
Timing: Inspect Before the Crate Is Closed
The best time for a PSI is after final inspection and before packing is sealed. Opening a closed crate to inspect what is inside is slow, risks damaging preservation, and usually means repacking. Checking before closure takes minutes.
Schedule the visit around the packing activity, not the shipping date. If the freight booking is fixed, work backwards from it and leave room for a failed inspection. A PSI with no schedule margin turns a finding into a missed vessel, and the pressure to waive the finding grows with every hour.
Where the equipment is large or heavy, agree in advance what can be inspected in position. Some items cannot be safely moved just to be examined, so the plan should name the viewing points and the conditions for access.
Packing and Preservation in Tropical Sea Freight
Equipment fabricated in Indonesia may travel by sea inside the archipelago or abroad, and equipment imported to Indonesia often arrives after a long sea voyage. Tropical humidity, salt air and handling at ports are the main enemies. Condensation inside a sealed crate can cause corrosion on machined surfaces long before the equipment is installed.
Preservation methods depend on the item, the route and the storage period, and they are normally specified in the order or the supplier’s procedure. A PSI checks that they were actually applied: protective coatings or films where required, openings sealed, moisture protection in place, and rotating parts secured against movement.
Marking matters as much as protection. Shipping marks, handling symbols and orientation arrows should be clear and consistent with the packing list. A crate that cannot be identified at a busy port or a remote site risks delay, damage or loss, however well it was preserved.
Reconciling Documents With the Physical Shipment
One of the most valuable parts of a PSI is the cross-check between papers and goods. The purchase order, commercial invoice, packing list, certificates and marks on the crates should all describe the same items in the same way. Discrepancies in quantities, descriptions or identification numbers are common, and they cause trouble at customs and at site receiving.
Whether a particular mismatch matters for clearance depends on the destination’s rules, so treat the inspector’s findings as input to your broker rather than as a substitute for their advice. What the inspector can do reliably is point out that the list says four items and the crate holds three, or that a serial number on the nameplate differs from the one in the data book.
Keep the report short and factual. It should list what was checked, how, against what, and what was found, with photographs where permitted. A clear record helps resolve any later dispute about whether damage occurred before or after the goods left the factory.
Sampling Versus Checking Every Unit
For one-off or low-volume equipment, such as a skid, a pump package or a switchboard, the sensible approach is to inspect every unit. There are few of them, the consequences of a defect are high, and sampling would save little.
For repetitive goods such as fittings, fasteners or valves, inspecting everything may be impractical. Attribute sampling schemes, such as the ISO 2859 series on sampling by attributes, give a structured way to decide how many pieces to check and how many defects justify rejecting a lot. The right plan depends on the item, the criticality and the supplier’s history, and it should be agreed in writing.
Whichever approach is chosen, the report should state it. A buyer reading “inspected” will assume every unit was examined unless the document says otherwise. G.I Quality Services lists pre-shipment inspection, visual inspection and documentation review among its services, and any provider should be able to describe its sampling basis as clearly.
Frequently Asked Questions
What is pre-shipment inspection?
It is an inspection carried out before goods are shipped to confirm they match the order in identity, quantity and condition, and that they are packed and documented for transport. The result is a report that supports the decision to release the shipment.
Is pre-shipment inspection mandatory in Indonesia?
A commercial PSI is normally a contractual choice made by the buyer. Whether any government requirement applies to your goods or route depends on the product and the rules in force, so confirm it with your customs broker or freight forwarder.
What is the difference between PSI and FAT?
A factory acceptance test checks that equipment performs as specified at the supplier. PSI checks that the equipment being shipped is the right item, in good condition, correctly packed and documented. They are complementary, not interchangeable.
How long before shipment should a PSI be scheduled?
After final inspection and before packing is closed, with enough margin to fix any findings before the booked sailing. Agree the notice period with the inspection provider at order stage.
Does a PSI guarantee the equipment will work?
No. It confirms identity, condition and documentation at the time of the inspection. Performance is proven by testing such as FAT and site acceptance tests, and a PSI report is not a performance guarantee.
Can PSI be done on equipment fabricated in Batam?
Yes, provided the inspection provider can attend the yard or workshop. Agree access, notice and scope with the vendor in advance so that the inspector can see the equipment before packing closes.
