Importing compressor parts from China: MOQ, packaging and lead time answered
Importing compressor parts from China? Straight answers on MOQ, sample orders, export packaging, lead time and documents before you request a quote.

Buying compressor consumables from a manufacturer in China is routine for many plants, but if it is your first import, the questions stack up quickly: how small can the order be, how is it packed, how long does it actually take, and which documents will you have to handle. Here are straight answers to the five questions that matter at the start, and how the process runs on our side in Ningbo.
How small can a first order be?
Our minimum order quantity is one piece. That is deliberate: a sample order lets you check the fitment and quality on one machine before you commit a budget line. Trial orders and mixed batches are accepted, so a first shipment can combine air filters, oil filters, and separators for different machines in your fleet on a single order instead of five separate ones.
What you should confirm about packing
Every quote we send includes packing information, which matters more in this trade than most buyers expect. Carton dimensions, units per carton, and gross weight decide your freight cost and your warehouse handling, so they belong in the comparison at the quote stage, not after the goods are produced. Export cartons are standard, and if your forwarder needs specific labeling or marking, it is easiest to agree on it while the quote is being prepared.
If this is your first shipment, forward the packing data to your freight forwarder before confirming the order. It takes one email at the quote stage and prevents most of the surprises at the freight-quote stage later.
How lead time is actually calculated
Total lead time is production time plus transit time, and the honest answer is that both depend on the order. Production depends on what is in the order and what is already in stock; transit depends on the destination port and the sailing schedule at the time of shipment. Sea freight is measured in weeks, not days, and adds port handling on both ends. What we commit to on our side is speed and clarity in the earlier stages: a quote, with packing information, usually within one working day, so the freight leg of your planning can start as early as possible.
One practical approach for urgent needs is to split the shipment: the critical items by air while the bulk of the order goes by sea, protecting the machine while the main consignment is on the water. Mention the deadline in your inquiry so packing and shipping options can be discussed with the quote.
The documents you will deal with
For a standard sea shipment, the document set is familiar to any customs broker: commercial invoice, packing list, and the transport documents for the shipment. If you work with a freight forwarder, they will tell you exactly which papers they need for clearance in your country, and we issue the standard export documents to match. The packing list generated from your order is also the document your warehouse team uses to check the goods on arrival, which is one more reason packing details are confirmed at the quote stage.
Why the supplier's location matters
Ningbo, in Zhejiang province, sits close to Ningbo Port, which keeps the inland leg of the export short and simplifies scheduling once goods are ready. Keli-Parts has been in compressor parts trading since 2002 and opened its own manufacturing plant in 2006, so the company that quotes your parts also makes them.
For maintenance consumables on a repurchase cycle, the practical benefit is consistency: we stock consumables against each customer's maintenance rhythm, typically a three-to-six-month repurchase cycle, so recurring orders are prepared rather than started from zero each time. We are also online 24/7, which matters when a machine is down and the conversation cannot wait for business hours.
Before you send your first inquiry
A strong first inquiry contains the same information as any other: compressor model, old part numbers, and expected quantities. Add your destination port and any packing requirements, and the quote you get back, usually within one working day, will already contain what your forwarder needs. Every part is covered by a 12-month warranty, and the fitment on every item is checked before quoting, which is what turns a first sample order into a dependable supply line.
