Consolidating a long aircraft parts list: fewer suppliers, invoices, shipments and customs entries
A fastener and consumables list for a fleet, or the material for a heavy check, rarely comes from one supplier. Buy each line where it is best and a few hundred lines become dozens of minimum charges, invoices, wires, certificates, tracking numbers and customs entries. This guide covers the four ways to consolidate, what each one merges and what it does not, the time you pay for it, and a checklist for the RFQ and the purchase order.
How one list turns into thirty orders
A fastener and consumables list for a fleet, or the material for a heavy check, is a few hundred lines of low-value parts. No single supplier stocks all of it. So the list goes out, and the answers come back one supplier at a time, each covering a handful of lines. Buy the best answer on every line and you have not placed one order. You have placed thirty.
In supplier quotes we received between June and September 2026, a supplier's reply carried a median of one priced line, and 96% of replies carried five lines or fewer. On our own RFQs where at least 20 part numbers were answered, the single supplier that covered the most lines typically covered fewer than half of them. 57% of offer lines stated a minimum in money: per order, per line or per transaction.
Each of those thirty orders carries overhead that does not scale with the value of the parts. A box of washers takes the same purchase order, invoice approval and wire transfer as a box of valves. Here is what multiplies:
| Multiplies per | What you handle | Why it hurts on a long list |
|---|---|---|
| Supplier | Minimum order or minimum line charge | A $30 line from a seller with a minimum order charge is billed at the minimum. One manufacturer's published terms, for example, allow a $250 minimum order charge on parts orders. |
| Supplier | Vendor approval, purchase order, order acknowledgment | Each new name is a vendor file to open and an acknowledgment to chase. |
| Supplier | Invoice and payment | Thirty invoices to match and approve, thirty wires, often each with its own bank fee, and thirty sets of bank details to verify. |
| Shipment | Freight charge, tracking number, packing list | Each parcel is billed and tracked on its own. Thirty tracking numbers is thirty chances for one box to go quiet. |
| Shipment | Export filing and import entry | Customs clears shipments, not your list. Each arrival is its own entry, and often its own broker fee. |
| Line | Certificate, trace, receiving inspection | This part does not consolidate, whatever you do. See below. |
The customs row is easy to underestimate. In the United States, for example, a shipment not exceeding $2,500 in value may go through informal entry; above that it is a formal entry, and a merchandise processing fee is charged per entry within a minimum and maximum. Elsewhere the principle is usually the same: the declaration follows the shipment. Thirty parcels arriving separately can mean thirty declarations, thirty broker invoices and thirty chances for a hold.
Four ways to consolidate, and what each one actually merges
“Consolidation” means four different things, and each merges a different part of the overhead.
| Approach | What gets merged | What stays separate | Works best for |
|---|---|---|---|
| One RFQ, one seller — send the whole list to a stocking distributor who sources the lines it does not hold | RFQ, PO, invoice, payment, one point of contact | Freight may still start in several countries; lines may arrive at different times | Long lists of low-value parts, where overhead is a big share of the cost |
| Freight forwarder consolidation — suppliers deliver to the forwarder, who ships one consolidated load | International freight, the export filing and the import entry at your end | Every PO, invoice and payment to every supplier | Buyers outside the country of the suppliers, with many domestic deliveries at origin |
| Kitting — a provider assembles all material for a check or a task into a kit | Sourcing, packing and delivery: one kit, one shipment | Planning: the kit list has to be right and agreed well before the input date | Scheduled heavy checks and repeat work packages |
| Fewer approved vendors — cut the supplier base on purpose | Vendor files, audits, terms, payment runs over time | Each order still ships as the vendor ships it | A buying department with steady repeat demand |
One RFQ for the whole list
You send the complete list to one seller and let it do the sourcing. You get one quote in one format, one purchase order, one invoice and one payment. The seller's price includes its margin, so compare the quote against the full cost of buying the same lines yourself, minimums and wires included. Line prices alone will make the one-seller quote look dearer than it is. Our guide to the true cost of an aircraft part walks through what belongs in that comparison.
Ask two questions before you choose. Does the seller show, per line, where the part ships from? And does it show the cost of getting each line to its own warehouse, or fold it into the price? A seller that sourced your lines from ten places still has ten inbound shipments to manage.
Freight forwarder consolidation
If you already have your suppliers and only the freight is the problem, a forwarder near your suppliers can receive the parcels, hold them and ship them onward as one consignment. That merges freight and customs at your end. It does nothing for the paperwork of thirty purchase orders.
Two catches. First, export filing. U.S. export filing (EEI) is not required when the value under one Schedule B number, from one exporter to one consignee on one conveyance, is $2,500 or less, unless the item needs an export license or falls under another case the regulations list. The test is counted per exporter, per consignee and per conveyance, so ask the forwarder how a consolidated load will be filed, and settle who files before the first parcel arrives; on an EXW purchase that question is less obvious than it looks (see EXW, FCA or FOB on an aircraft parts quote). Second, dangerous goods. Sealants, some chemicals and batteries turn up on consumables lists, and a hazardous material offered for transport needs a shipper's certification and proper packing. Tell the forwarder which lines are regulated before they arrive, not when the consolidation is being built.
Kitting
A check kit is, in one kitting provider's words, “a group of parts that satisfy your material requirements”, often a mix of rotables, expendables and consumables, delivered in one shipment from one location. It is the fullest form of consolidation, and it asks the most of you up front: the material list has to come from the work package, and it has to be frozen early enough for the kitter to source it. It suits scheduled checks. It does not suit the list you need to fill this week.
Fewer vendors
A slow structural fix rather than a tool for one list, but worth doing alongside the other three: every supplier you keep is one more set of minimums, terms and bank details to keep current.
The price of consolidating: the slowest line
Consolidation trades overhead for time. A consolidated shipment leaves when its last line is ready, so the list moves at the pace of its slowest part, and a long list almost always has one slow line. In the supplier quotes we received between June and September 2026, where lead time was written in days, the median was seven days and the 90th percentile 108. One line in ten can hold the other nine for months.
So decide in advance how the order may be split, and write it on the purchase order. Under the U.S. Uniform Commercial Code, if the contract is silent, “all goods called for by a contract for sale must be tendered in a single delivery”. Other legal systems have their own defaults, and a seller's terms may say something else again. Do not rely on any default. Say it.
| PO instruction | What you get | Use it when |
|---|---|---|
| Ship complete | One shipment, one entry, one receiving event; waits for the slowest line | Every line has a short, confirmed lead time, or nothing is needed until the whole list is |
| Partial shipments acceptable | Parts as they become available; more parcels, freight minimums and entries | Lines are needed at different times, or one line has a long lead time |
| Ship complete by group | Stock lines together now, long-lead lines together later | Most long lists. Usually the best compromise |
| Ship-by date per line | The seller ships each line so it arrives by its date | A heavy check with a known input date and a known task sequence |
Partial orders are the other half. Some lines will not be available at all, or not in a condition or quantity you can use. Decide whether the seller may accept the lines it can supply and decline the rest. A decline you can see line by line is far easier to re-source than a silence discovered at receiving.
And keep AOG out of it. An aircraft-on-ground line inside a 300-line consolidation waits for the consolidation. Send it separately, as described in our RFQ guide.
Paperwork does not consolidate
You can merge freight, invoices and payments. You cannot merge airworthiness paperwork. Every line still needs its own certificate or certificate of conformance, and its trace where you asked for one. At receiving, the Aviation Suppliers Association's advice for an 8130-3 is to correlate the form to your purchase order and make sure blocks 7–11 match the part you receive. In a mixed box of 200 lines that only works if the paper is organised for it.
- Ask for your PO line number on the packing list and, where possible, on each part's bag or tag.
- Keep each certificate with its part. A forwarder or consolidator repacking boxes must not separate them, so say so in the instructions.
- Ask for scans of the paperwork before shipment on lines where a wrong certificate would mean a return. Finding it on line 187 after the consolidation has landed is the expensive way.
Checklist: consolidating a long list
Use it on the RFQ and repeat the answers on the purchase order, so that what you asked for and what you ordered say the same thing.
On the RFQ
- Send the whole list as one file, one part number per line, with quantity and unit of measure. Mark which lines are needed first.
- State the acceptable conditions and certificate per line, including where a CoC is enough.
- Ask for these per line: lead time in days, ships-from country, minimum order, and whether freight to the seller's warehouse is included or extra.
- Ask whether the seller can quote the whole list, and whether a line it cannot supply will be marked “no quote” rather than left out.
- Name your ship-to country and delivery term, and ask which lines are dangerous goods or export-controlled.
- Pull out AOG lines and send them separately.
On the purchase order
- Shipping instruction: ship complete, partial shipments acceptable, ship complete by group, or a ship-by date per line. Write one.
- Partial acceptance: may the seller accept only some lines? Ask for the decline line by line.
- Invoicing: one invoice for the order, or one per shipment, and whether several invoices can be paid in one transfer.
- Paperwork: certificate type per line, kept with the part, PO line numbers on the packing list.
- Consolidation point, if you use a forwarder: its address, and who files the export.
- Tracking: one master tracking number per shipment, sent when it leaves.
Sending the whole list to MG AVIATION TECH
If you take the first route, you can send us the whole list. Send it as it leaves your system to [email protected], in your own file: Excel, PDF, a scan or the body of an email, five lines or five hundred. Your inquiry will be reviewed by a specialist within one business day.
Customers with an RFQ Radar account can upload the same file in the portal (Excel, CSV or PDF up to 10 MB) and follow the answer there. Every line comes back with condition, certificates, quantity, unit price in US dollars, lead time in days and minimum order. Where the supplier states it, the line also shows the country the part ships from. Prices are Ex Works our warehouse in Orlando, FL, and the cost of bringing a line to Orlando is shown separately, per line, as “Shipping / line”, so you can see what each line costs to bring in. You put the lines you want on one purchase order, and several invoices can be put on one group invoice and paid in a single transfer.
Send the whole list, not thirty RFQs
