This is a neutral, research-based overview of Loongbuy and the "Loongbuy spreadsheet" that circulates among reverse-shopping communities. It aggregates verifiable public information and points you to primary sources rather than personal purchase stories. We have not placed test orders through Loongbuy, so you will find no invented order numbers, landed-cost figures, or self-assigned star ratings here. Where fees, shipping rates, or coupons matter, the only reliable figure is the one shown in your own Loongbuy cart at checkout — treat every number below as context, not a quote.

What is the Loongbuy spreadsheet?

A "spreadsheet" in this niche is a community-maintained list of product links (usually Taobao, Weidian, or 1688 listings) paired with a recommended buying agent. Loongbuy is one such agent. As Repsheet's tutorials describe the general workflow, a buying agent purchases the item from the Chinese marketplace on your behalf, receives it into a domestic warehouse, photographs it for quality control, and then forwards it internationally once you pay for shipping. Loongbuy operates this same reverse-purchasing model for Taobao, Weidian, and 1688 sources.

It is worth understanding that these agents are largely interchangeable. Aggregator sites such as JadeShip list Loongbuy alongside Kakobuy, Joyagoo, Acbuy, Mulebuy, Allchinabuy, Hoobuy, Superbuy, Cssbuy, Oopbuy, and others — and the same spreadsheet link will typically resolve through any of them. The agent you pick mostly changes the fee structure, the warehouse, and the shipping-line options, not the underlying product.

Fees, coupons and hidden costs

Loongbuy, like its peers, charges a service commission on top of the item price, plus warehouse and handling fees. Across the broader agent market, commissions tend to sit in a roughly 0–10% band: HowToTao's comparison puts Basetao around 0–5%, Cssbuy around 3–6%, and several agents at a flat 10%. Loongbuy falls inside this range, but the exact percentage, any bulk-order discount, storage grace period, repackaging charge, and return handling fee change over time and by promotion.

For that reason we do not publish a fixed Loongbuy fee or any "first-order" coupon code here — codes expire, get revoked, or differ by region, and reprinting one as "verified" would mislead you. Log into Loongbuy, add a real item to your cart, and read the itemized fee breakdown before you commit. The commission is usually the smallest line on the invoice anyway; shipping and duties dominate the total.

Shipping cost & the 2025 customs change you must know

The single biggest shift for 2026 buyers is on the import side, not the agent side. The United States has eliminated the de minimis exemption that previously let low-value parcels enter duty-free. A White House fact sheet closed the exemption for China-origin goods effective May 2, 2025 — and noted CBP was processing over 4 million de minimis shipments daily before the change. A later presidential action then suspended duty-free de minimis treatment for shipments from all countries, effective August 29, 2025, "regardless of value."

To grasp the scale, CBP data summarized by Red Stag shows roughly 1.36 billion such parcels in FY2024 at an average value near $45 — exactly the kind of small haul agent shoppers send. The practical takeaway: any older guide implying that a parcel under $800 slips into the US duty-free is now outdated. For 2026, budget for potential import duties and brokerage on top of Loongbuy's quoted line-haul shipping, and confirm your country's current rules before checkout. The agent's per-kilogram rate is only part of your landed cost now.

QC photos: what to check

Loongbuy provides QC photographs at its warehouse before you pay for international shipping. Use them deliberately rather than rubber-stamping them. A sensible inspection checklist:

  • Confirm the correct colorway, size, and variant against your original listing.
  • Look at stitching, logo alignment, and any printed text for obvious defects.
  • Check that hardware (zippers, buttons, soles) matches the photos in the listing.
  • Verify the quantity and that no item is visibly damaged or stained.
  • Note the measured weight, since it drives your shipping quote.

If something looks wrong, raise it before consolidation and shipment — that is the entire point of the QC step.

Loongbuy vs other agents

Compare agents on total landed cost, not headline commission. As NewBuyingAgent's scoring review argues, a low service fee can be erased by higher freight, worse consolidation, or slower handling. Two agents quoting the same item price can differ substantially once shipping line, volumetric weight, and now import duties are added in.

Because Loongbuy, Kakobuy, Joyagoo, Oopbuy, and the rest source from the same marketplaces, the differentiators are shipping-line selection, warehouse consolidation efficiency, customer support responsiveness, and dispute handling. The most reliable way to compare is to build an identical cart in two agents and read the full quote — including any duty estimate — side by side.

Loongbuy reputation (third-party)

For independent feedback, consult Loongbuy's third-party review profile directly: trustpilot.com/review/loongbuy.com. We are deliberately not quoting a TrustScore number, because that figure moves and we cannot verify a specific value at the moment you read this. Open the profile yourself for the current score, and read both the recent 5-star and recent 1-star reviews — the 1-star reports (typically shipping delays, lost parcels, or refund disputes) tell you how the company handles problems, which matters more than the average.

Why people use agents (market context)

Demand for reverse-buying agents rides on the broader cross-border e-commerce boom. Market.us values the cross-border e-commerce market at about USD 2.2 trillion in 2024, with projections toward USD 18.2 trillion by 2034. Agents let overseas shoppers reach Chinese marketplaces that otherwise do not ship internationally or accept foreign cards.

A frank caveat: many spreadsheet listings are replica or counterfeit goods. The OECD's 2025 report put global trade in fake goods at roughly USD 467 billion, and counterfeit-footwear statistics compiled by RunRepeat show how concentrated this is in sneakers — a staple of agent spreadsheets. Know what you are buying, and the legal and seizure risk that can come with it.

Pros and cons

Pros: access to Taobao, Weidian, and 1688 listings that do not ship abroad; warehouse consolidation to cut per-parcel shipping; QC photos before final dispatch; commission within the normal market band; an established third-party review presence.

Cons: fees and shipping rates change without notice and must be checked live; international shipping plus 2025-era import duties can dwarf the item price; dispute and refund outcomes vary, as third-party reviews show; and much of the listed inventory may be replica goods carrying legal and customs risk.

FAQ

Is Loongbuy a scam? It is an established reverse-buying agent with a public Trustpilot profile, not an anonymous storefront. Read the recent reviews there yourself and form your own view before sending money.

Will I pay import duties in 2026? Most likely yes. The US ended duty-free de minimis treatment in 2025 for all countries, so parcels that once entered duty-free can now incur duties regardless of value. Budget for them and confirm your own country's rules.

How much does Loongbuy charge? A service commission within the roughly 0–10% market band, plus warehouse, handling, and shipping fees. Check the itemized total in your own cart — that is the only accurate figure.

Can I trust the QC photos? They are a genuine and useful checkpoint, but you must actively review them for variant, defects, and quantity before paying for shipping. They confirm what arrived at the warehouse, not authenticity or legality.

Bottom line

Loongbuy is a mainstream, functional buying agent comparable to its many peers; the product you receive depends far more on the original marketplace listing than on which agent forwards it. Choose on total landed cost — commission plus freight plus 2026 import duties — rather than on the advertised fee, verify every charge in your own cart, and read Loongbuy's live Trustpilot profile before deciding. We assign no numeric rating, because a trustworthy verdict here is the one you reach from primary sources, not a number we invented.
