What are the document requirements for US LDP General Ship?

If you’re a seller (like me, someone who’s been doing US LDP general ship for 8 years) trying to lock in a deal with a US buyer, you already know LDP isn’t just “drop it at the port in China” — it means you’re on the hook for every single document that keeps your shipment moving from your warehouse to the buyer’s dock in the States. Mess up even one, and your cargo could get stuck at customs, get fined, or even sent back, and trust me, no one wants to deal with that headache. US LDP General Ship

First off, let’s get clear on what “general ship” means here: it’s not bulk grain or oversized machinery — it’s the regular, everyday stuff like consumer electronics, apparel, small home goods, and non-hazardous parts that most small to mid-sized businesses move. LDP (Delivered Duty Paid) means I, as the supplier, cover everything until it’s in the buyer’s hands: shipping, insurance, US import duties, taxes, customs clearance, and all the paperwork needed to cross the border. No exceptions.

I’ve seen so many new suppliers skip a step because they thought it was trivial, so let’s break down the documents you actually need, organized by when you’ll need them — way simpler than trying to memorize a random list.

Documents You Need Before Shipping (Pre-Export)

These are the ones you get out first, to lock in a freight forwarder and make sure your export is legal.

Commercial Invoice
This isn’t just a receipt for your buyer — it’s the core document for every step. US customs uses it to calculate duties and taxes, the freight company uses it for a bill of lading, and your buyer uses it to prove ownership for their inventory. I always make sure mine has 7 key things:

Full names and addresses of both the seller (me) and buyer (no generic “company address” — exact street, city, zip, and US tax ID if the buyer has one)
Unique invoice number (tracks every shipment, so no mix-ups with 50 other orders)
Date the invoice is issued (before shipping, duh)
Detailed breakdown of each item: quantity, description (no vague “clothes” — specify “men’s cotton t-shirts, size M, 100% cotton” so customs doesn’t flag it), unit price, and total value
Terms of sale: clearly state “LDP US Port of Destination” (I add this in big bold at the top so no one misses it)
Country of origin for each item (super important — if it’s made in China, write that, not “assembled in Vietnam”)
Signature from an authorized person at my company (no stamped only — customs needs a physical or e-signature from someone who works there)

Packing List
Your commercial invoice lists values, but the packing list is all about physical details to match up with your shipment. I make this match every single item in the cartons:

Number of cartons (e.g., “12 total cartons, each marked #1/12 to #12/12”)
Net weight (per carton and total) and gross weight (which includes packaging, so add a few pounds extra for boxes)
Dimensions of each carton (length x width x height) — US freight companies use this to calculate container space and shipping costs
A quick check: I cross-reference this with the commercial invoice before sending it to the forwarder. Last year, I sent a 100-piece order with a packing list that only said “50 pcs total” — the forwarder almost loaded a container that was way too small, and I had to pay a $200 rebooking fee. Oops, don’t be me.

Shipper’s Export Declaration (SED) — Now Known as the Electronic Export Information (EEI)
This one tripped up so many of my early shipments, and I still get emails from new sellers asking what it is. If your shipment is over $2,500 in total commercial value (per item line or whole invoice) or is on a US munitions list (rare for general ship), you must file EEI through the Automated Export System (AES) before your cargo leaves the US. Wait, no — wait, you file this from your country, right? Yeah, if you’re shipping from China (where I’m based), you use China’s e-port system to file AES Direct, which then sends the info to US customs. The key tip: get the EEI number (it’s a 14-character code) and put it on your commercial invoice. If you don’t, US customs will hold your shipment at the port, and your buyer will be waiting weeks for their stuff. I always set a calendar alert for this 3 days before loading, because sometimes the AES system is slow, and I need to catch errors early.
Certificate of Origin (COO)
This is the document that proves where your product was made. For general ship, US customs requires this if the product’s origin is not obvious (but honestly, I include it for every LDP shipment just to avoid hassle). There are two types:

Non-preferential COO: This is the standard one, issued by your local chamber of commerce or a third-party agency, stating “this product is manufactured in [China]”. It’s not for preferential tariffs, but it’s required to confirm origin.
Preferential COO: Only use this if your product qualifies for a free trade agreement (FTA) between your country and the US. For example, if you’re shipping from Vietnam and your goods meet the US-Vietnam FTA rules, a Form A COO cuts down duties. But for most general consumer goods, the non-preferential one is all you need. I always keep a copy scanned and in my digital folder for every shipment, so I can pull it up in 2 seconds if customs asks.

Documents You Need During Transit (Crossing US Customs)

These are the ones that are most likely to get lost, so I always send them to the forwarder twice: once electronically, and once as a physical copy with the shipment (inside a waterproof pouch on the outside of the container, so it doesn’t get ruined by rain or sea spray).

Bill of Lading (B/L)
This is the most important legal document of all — it’s your proof that the freight company has your cargo, and it’s your buyer’s proof that they own it once it’s delivered. For LDP, I always ask for a “negotiable sea waybill” (or a non-negotiable one, sometimes called a straight B/L) instead of a full negotiable B/L. It’s cheaper and faster for US imports, because you don’t have to deal with sending original physical bills via courier (which can get lost for 3+ days). The B/L needs to match your commercial invoice almost exactly: same buyer name, same port of destination, same total quantity. If it doesn’t, the forwarder will have to file a correction, which adds delays and sometimes fees. Last month, a forwarder gave me a B/L with the wrong port — they put “Los Angeles” instead of “Long Beach” for a shipment going to a warehouse in Long Beach, and I had to pay $500 to reroute it. I check every line of the B/L before signing.
Import Filings for US Customs and Border Protection (CBP)
This isn’t a paper document I send to the buyer — it’s something my freight forwarder files on my behalf, but I need to make sure I give them the right info to avoid mistakes. The main ones here are:

CBP Entry Form (Customs Form 7501): This is the official entry form that lists all shipment details, duties, and taxes. I make sure my commercial invoice has the exact HS (Harmonized System) code the forwarder needs — HS codes are 6-10 digit numbers that classify every product for duties. If I put the wrong HS code (e.g., a t-shirt is code 61091000, not a random number), customs will calculate the wrong duty, and I’ll end up paying more than I should. I always double-check HS codes with my forwarder before shipping.
Automatic Export System (AES) Confirmation: The EEI number I mentioned earlier — CBP matches this to your shipment to make sure you didn’t skip the filing requirement. If the number is missing, CBP will hold your cargo until they get it, which can add 7-10 days to delivery.

Insurance Certificate
LDP means I cover the cost of insurance for the shipment, right? So I need to give the buyer a certificate that proves the cargo is insured from my warehouse to the buyer’s dock in the US. The minimum coverage is usually 110% of the total shipment value, which is standard for ocean freight. I always make sure the certificate names the buyer as the “insured party” (or as a loss payee) so if there’s damage or loss, they can file a claim directly. No buyer wants to wait for me to handle a claim when their shipment is stuck at sea — this cuts down on headaches for everyone.

Documents You Need After Delivery (Post-Shipping, For Record-Keeping)

These are the ones you don’t have to send to the buyer, but you must keep for at least 5 years (US CBP audits importers regularly, and even as a supplier, you need to have proof of every shipment). I keep all my documents in a cloud folder labeled by shipment number, so I can pull them up in 2 minutes if an audit happens:

Delivery receipt: A signed document from the buyer’s warehouse confirming they received the shipment, with any notes about damage (if any)
Duty payment receipt: Proof that I paid all US duties, taxes, and customs fees — this is important for my own records and if the buyer ever asks for proof of LDP costs
Any correction documents: If I had to fix a B/L or HS code mid-shipment, I keep those too, because CBP might ask for them later.

Common Mistakes I See New Suppliers Make (And How To Avoid Them)

I’ve messed up almost all of these once, so I know how annoying they are:

Skipping the EEI: If your shipment is over $2,500, you have to file it. I once sent a $3,000 order without it, and CBP held it for 10 days while I scrambled to file, costing me a $1,200 late fee with the buyer.
Vague descriptions on invoices: I had a shipment once labeled “toy” on the invoice — customs thought it was a battery-powered toy and flagged it for hazardous material, even though it was just a stuffed animal. The delay cost me $800 in storage fees. Always be specific.
Using generic addresses: If your buyer has a US tax ID (they should, for import purposes), add it to the commercial invoice. Without it, customs can’t confirm their tax status, and they’ll have to pay extra taxes.

At the end of the day, US LDP general ship documents aren’t just red tape — they’re how you make sure your shipment gets to the buyer on time, no surprises. I’ve built my business on getting this right every time, and now my clients come back because I don’t cut corners on paperwork. If you’re a buyer looking to lock in a reliable LDP general ship supplier, or you’re a seller who needs help sorting out your documents, hit me up to chat through your needs — no jargon, just straight talk about what works for your shipments.
