What Nigeria imports to mix concrete, and which tier your job sits in

Nigeria buys concrete mixing equipment on two customs lines that have almost nothing in common. Under HS 8705.40, concrete-mixer vehicles, China declared 500 units shipped to Nigeria in 2024 worth USD 17,059,968, which is USD 34,119 each. Under HS 8474.31, concrete or mortar mixers, the same year's declaration records 2,495 units worth USD 6,331,809, or USD 2,537 each. The weights separate them further than the values do. The vehicle line carries 6,501,540 kg across its 500 units, 13,003 kg apiece; the mixer line carries 1,997,463 kg across 2,495 units, 801 kg apiece. Divide the one per-unit weight by the other and a unit on the vehicle line weighs 16.24 times what a unit on the mixer line weighs. Neither figure is a price we quote: both are customs values declared at the point of export, before freight, duty, certification and any margin.

This matters the moment an enquiry says "concrete mixer". The phrase covers a self-propelled machine with a cab that loads its own aggregate, weighs it, mixes it and discharges it, and it equally covers a drum on a frame that two men lift off a pickup. The certificate your agent files, whether vehicle rules attach, how the unit travels and what it costs to land all change completely depending on which one is meant — and the record shows Nigerian importers buying both in volume in the same year. So the first thing to settle is not who supplies the machine but which of the two lines the job sits on, and it is settled on paper by a broker rather than assumed from a product name. The Nigeria market guide on this site sets out the import sequence that follows, and every step of it assumes the heading is already fixed.

The cheaper heading is the one carrying the volume, and not only in Nigeria. In 2024 China declared 8,560 concrete or mortar mixers to four African markets — 3,213 to Tanzania, 2,495 to Nigeria, 1,500 to Kenya and 1,352 to Ghana — at country averages running from USD 1,252 to USD 2,824. That is the level this market is used to seeing attached to the words "concrete mixer". Nigeria's vehicle-heading average of USD 34,119 is 13.44 times its own mixer-heading average. A dealer quoting a self-loading machine into Nigeria is not principally competing with another self-loader; he is competing with the number already in the buyer's head from the other heading. The answer to that is a landed figure the buyer can set against his own cost of doing the job another way, which is what the CIF Lagos quotation guide on this site sets out gate by gate.

The same heading also moves year to year in a way that should stop anyone treating its average as a price. In 2023 China declared 5,103 units to Nigeria at an average of USD 915.50 and 335 kg each; in 2024, 2,495 units at USD 2,537 and 801 kg each. Half the units, nearly three times the value apiece, and more than double the weight apiece. Across the whole 2019 to 2024 sample this heading has a median of 194 kg per unit and a coefficient of variation of 207.5 per cent, which is another way of saying it is not one product. The band quoted above is therefore a fact about what was declared in one year, not a benchmark to price against, and nothing on this page uses it as one. A buyer who has been shown a figure from this heading and a figure from the vehicle heading has been shown two markets, not one price range.

There is a middle class of machine in the customs record, and it is filed under the cheaper heading. Filter China's 2024 declarations under HS 8474.31 to consignments whose declared net weight per unit falls between 4,000 and 20,000 kg — heavy enough that a portable drum mixer cannot account for it — and thirteen destinations remain, 1,375 units and USD 20.7M between them. Guinea took 297 units averaging 4,181 kg and USD 10,426 each; Ethiopia took 252 averaging 5,970 kg and USD 11,522. Across all thirteen the per-unit weight runs from 4,115 kg to 15,306 kg, which is twenty-one to seventy-nine times the 194 kg median of the heading they were filed under. Those are plainly different machines sharing six digits. The inference is ours and worth naming as one: nothing in the record says what these units are, only what they weigh.

Nigeria is not among those thirteen destinations. Pakistan, Guinea, Ethiopia, Bangladesh, Bolivia, Mali, Dominica, Burkina Faso, Sudan, São Tomé and Príncipe, the Central African Republic, Guinea-Bissau and one residual Asian grouping are; Nigeria is not. That cuts against the convenient story. On this evidence the middle tier does exist and does travel under the mortar-mixer heading, and in 2024 it did not travel to Nigeria that way. What Nigeria took that year was 500 units on the vehicle line and 2,495 on the mixer line, with nothing visible between them. Whether that reflects Nigerian classification practice, a real absence of demand in the middle, or machines filed under a heading this query never touched, the record cannot say — and the three explanations point at completely different commercial conclusions, which is why none of them is asserted here. What can be said is that the gap is in the data as well as in the market.

Nigeria files a value for this heading and does not file a count. Its 2024 return under HS 8705.40 shows 285.93 units imported from the world against a CIF value of USD 18,103,780, and 275.978 units from China against USD 17,473,627 — both carrying the database's estimated-quantity flag, and neither being a whole number, which is the first sign that nobody counted anything. Divide each value by its own quantity and both land on USD 63,315 per unit. The quantity is the value divided by a constant: arithmetic performed on a declared value, not an observation of machines crossing a border. It is also the only Nigerian import quantity anywhere in the material behind this page, so there is no declared Nigerian count for this heading to publish, and this page does not manufacture one.

The two records also disagree, in a direction that differences of scope cannot explain. China declares 500 units leaving for Nigeria in 2024; Nigeria's estimate for arrivals from China is 275.978, and its estimate for arrivals from the whole world is 285.93 — smaller than one supplier country's declared outbound total. Timing across a year end, national subheadings below six digits and the valuation basis itself can all open gaps like this, and nothing in these records separates them; this site's 2024 destination map for the same heading runs the test across twelve reporting countries, and four fail it outright. One trap is worth naming: Nigeria's response returns identical numbers on four rows, split only by customs procedure and mode of transport. Summing them gives 1,143.7 units and USD 72.4M, four times the truth.

The machine that normally clears HS 8705.40 into Nigeria is heavier than any self-loading mixer we hold a confirmed weight for. China's 2024 declaration puts 6,501,540 kg across 500 units on that lane, 13,003 kg per machine, declared rather than estimated on both terms; the 2023 lane, on 230 units, sat at 13,823 kg. That is not a Nigerian peculiarity — across 308 country-years in the same dataset with twenty units or more the median is 13,617 kg per unit at a coefficient of variation of 12.5 per cent, which for customs data is a tight distribution. Three of the sixteen self-loading mixers in our specification file carry an operating weight: 5,800 kg on one and 8,500 kg on two others. The other thirteen carry none. But the customs figure is net weight declared on a shipment and ours is operating weight taken from a specification, and we have not established that the two are measured the same way.

The job this equipment is bought for gets described the same way wherever it comes up: a pour with no batching plant within useful reach, a site in an old district a full-size truck mixer cannot get into, a road where the pour front moves all day, or a self-build house where hand mixing is the alternative. What decides whether a machine can serve that job is not drum volume but width, because width is what a gate, a lane or a half-closed street measures. It is also the dimension with no remedy downstream: a height problem has answers at the port, an open top or a flat rack, and a width problem has none. So width is the first thing to establish, and it is the thing we can answer for across the range rather than for one machine at a time.

Ten of the sixteen self-loading mixers in our specification file carry a measured overall dimension. Across those ten, width runs from 1.60 m to 2.30 m and length from 4.35 m to 7.06 m. Heights are recorded between 2.45 m and 2.90 m, but only one of the ten — the SLM-18, at 7.06 m long, 2.21 m wide and 2.58 m high — comes with a drawing that separates the height of the machine travelling from the height with its drum raised. For the other nine the record does not state which posture was measured, and because the drum lifts, that gap falls on the height and not on the width. Width is therefore the number worth quoting to us and the number we can answer. If access is your constraint, put the metres in the enquiry.

The same ten records are thin in other places, and that decides how this page talks about them. Nine of them carry no rated power, no drum volume and no operating weight, and eight of those nine name an engine model without naming its maker, which is an incomplete identification rather than a full one. This site attaches a specification to a model number only where the whole required set is present, and at the moment that is one model. Everything above is therefore a range across machines rather than a line of figures against a name. Four of the six published models have no dimensioned drawing in our hands at all, so they carry no width here and no container verdict. A supplier who fills that column from a similar machine has not helped you; he has moved the risk from his quotation to your booking.

What the machine does on site is a cycle, and the specification file evidences it rather than asserting it. All sixteen self-loading mixers carry a configuration list — fifteen of them full lists of six to eleven items, the sixteenth a single item and an open query to the plant. Those lists name articulated steering, a drum that lifts and rotates through 270 degrees, a self-drawing water system with an on-board tank, a driving and mixing camera, independently replaceable mixing teeth and a reinforced frame; three of them name an eight-wheel drive chassis. The machine loads its own aggregate, mixes on the way to the pour front and discharges where it stands. How that compares with the crew you run today is arithmetic only you can do, against your wage rates and your pour sizes. This site publishes no output figure, no daily volume and no crew-equivalent number, because no plant has put any such figure in writing to us.
